What is TPO Roofing? Understanding Thermoplastic Polyolefin Membranes

TPO (Thermoplastic Polyolefin) roofing has emerged as the most popular single-ply roofing membrane in North America, accounting for over 40% of the commercial roofing market. This remarkable growth reflects TPO's unique combination of affordability, durability, and energy efficiency that makes it ideal for South Carolina's demanding coastal climate.

At its core, TPO is a single-ply roofing membrane composed of polypropylene and ethylene-propylene rubber polymerized together. This creates a flexible yet durable sheet that can be manufactured in various thicknesses (typically 45, 60, or 80 mil) and widths (10, 12, or 20 feet). The white or light gray surface contains reflective pigments and UV stabilizers that enable TPO to reflect up to 90% of solar radiation—a critical advantage in Myrtle Beach where cooling costs dominate energy bills for 7+ months each year.

What sets TPO apart from older flat roofing materials is its heat-welded seam technology. Unlike EPDM rubber roofing that relies on adhesives or tape for seam connections, TPO seams are fused together using specialized hot-air welding equipment operating at 900-1200 degrees Fahrenheit. This process creates molecular bonds stronger than the membrane itself, resulting in a monolithic, watertight surface with no weak points at the seams. In a region prone to heavy tropical rainfall and hurricane-driven wind and water, this seam integrity provides essential protection.

Our certified installers undergo continuous training to ensure every TPO roof we install meets or exceeds both manufacturer specifications and South Carolina coastal building codes.

Why TPO Roofing is the Smart Choice for Myrtle Beach Properties

Myrtle Beach presents unique roofing challenges that TPO is specifically engineered to handle. From salt air corrosion to hurricane-force winds to intense summer heat, our coastal environment demands roofing materials that can perform under extreme conditions. Here's why property owners throughout the Grand Strand are increasingly choosing TPO for their flat and low-slope roofing needs.

Extreme Heat Reflection

Myrtle Beach averages over 210 sunny days annually with summer temperatures regularly exceeding 90 degrees Fahrenheit. Traditional dark roofing materials absorb this heat, raising roof surface temperatures above 160 degrees and forcing air conditioning systems to work overtime. White TPO membranes reflect up to 90% of solar radiation, keeping roof surface temperatures 50-60 degrees cooler. This translates to 25-40% reduction in cooling costs—a significant savings when cooling season extends from April through October.

Hurricane Resistance

Living in coastal South Carolina means preparing for hurricane season every year. TPO roofing systems can achieve wind uplift ratings exceeding 120 mph when properly installed using mechanically fastened or fully adhered methods. The heat-welded seams create a continuous membrane with no gaps for wind-driven rain to penetrate. During hurricanes Florence and Dorian, properly installed TPO roofs in our service area demonstrated superior performance compared to traditional roofing systems, with minimal documented failures.

Salt Air Performance

Properties within miles of the Atlantic Ocean face constant exposure to salt-laden air that accelerates corrosion of metal components and degrades many roofing materials. TPO is inherently resistant to salt air corrosion—the membrane itself contains no metal components that can rust or corrode. All flashings and penetrations can be fabricated from TPO or stainless steel to eliminate corrosion points. This makes TPO ideal for oceanfront hotels, beach condominiums, and commercial properties throughout the Grand Strand.

Humidity Resistance

Myrtle Beach experiences average humidity levels of 70-80%, creating conditions that promote mold, mildew, and algae growth on many roofing surfaces. TPO membranes are naturally resistant to these biological growths—the smooth, non-porous surface provides no foothold for organisms to establish. Unlike built-up roofing or modified bitumen that can trap moisture, TPO sheds water completely and dries quickly after rain, preventing the moisture accumulation that leads to premature roof failure.

UV Stability

Intense UV radiation in coastal South Carolina causes many roofing materials to degrade prematurely—asphalt shingles lose granules, rubber membranes crack, and coatings fade. TPO membranes contain advanced UV stabilizers that maintain membrane integrity and reflectivity throughout the roof's lifespan. Quality TPO maintains its bright white appearance and reflective properties for 15-20+ years without significant degradation, ensuring long-term energy efficiency benefits.

Cost-Effectiveness

TPO offers the best value proposition in the single-ply roofing market. At $5-10 per square foot installed, TPO costs 10-20% less than PVC while providing comparable performance for most applications. When combined with energy savings of 25-40% on cooling costs, many building owners see complete return on investment within 5-7 years. Add in the 20-30 year lifespan and minimal maintenance requirements, and TPO delivers the lowest total cost of ownership among flat roofing options.

Our Recommendation for Myrtle Beach

For most commercial and residential flat roofing applications in Myrtle Beach, we recommend TPO as the optimal choice. The combination of heat-welded seam strength, superior energy efficiency, and competitive pricing makes TPO the best value for Grand Strand property owners. The white reflective surface is particularly valuable in our hot, sunny climate where cooling costs can dominate utility bills.

We recommend PVC over TPO in specific situations: restaurants with rooftop grease exhausts, manufacturing facilities with chemical exposure, and buildings requiring the absolute highest chemical resistance. For shaded flat roof areas where energy efficiency is less critical and budget is the primary concern, EPDM remains a viable option.

During your free consultation, our roofing specialists will assess your specific property needs, building use, and budget constraints to recommend the optimal membrane system. We install all three single-ply types and will always recommend what's best for your situation rather than pushing a single solution. Learn more about all our flat roofing options.

Commercial TPO Roofing Applications

TPO has become the dominant roofing choice for commercial buildings throughout the Myrtle Beach area. From oceanfront hotels to inland shopping centers, TPO delivers the performance commercial property owners and managers demand.

Hotels and Hospitality

The Grand Strand's hospitality industry relies on TPO roofing to protect their significant investments. Hotels and resorts benefit from TPO's energy efficiency (reducing cooling costs in rooms and common areas), hurricane resistance (minimizing storm-related closures), salt air durability (eliminating corrosion concerns), and clean white appearance (maintaining property aesthetics). We have installed TPO systems on hotels ranging from boutique properties to large resort complexes throughout Myrtle Beach, North Myrtle Beach, and Surfside Beach.

Retail and Shopping Centers

Retail properties with large flat roof areas achieve substantial energy savings with TPO. A typical 50,000 square foot shopping center can save $15,000-25,000 annually in cooling costs compared to dark roofing materials. TPO's quick installation minimizes business disruption, and the 20-30 year lifespan reduces long-term maintenance costs. We work with property management companies throughout Horry and Georgetown counties to maintain and replace retail roofing systems.

Office Buildings

Professional office buildings benefit from TPO's combination of durability and energy efficiency. The white membrane keeps interior spaces comfortable while reducing HVAC loads, and the watertight seams protect sensitive office equipment and documents from water damage. Many office buildings along Myrtle Beach's business corridors feature TPO roofing systems we installed and maintain.

Industrial and Warehouse

Large industrial facilities with extensive flat roof areas represent ideal candidates for TPO. The cost per square foot decreases with project size, and energy savings scale proportionally with roof area. TPO handles the foot traffic associated with rooftop HVAC maintenance and accommodates solar panel installations. We have completed TPO installations on warehouses and manufacturing facilities exceeding 100,000 square feet throughout the region.

Multi-Family Housing

Apartment complexes and condominium buildings rely on TPO for flat roof sections, breezeways, and common area structures. The energy efficiency benefits reduce utility costs for both building owners and tenants, while the durability ensures long-term protection without frequent maintenance requirements. We work with HOAs and property management companies to maintain multi-family TPO roofing systems throughout the Grand Strand.

Residential TPO Roofing Applications

Most roofing companies overlook residential TPO applications. At Weather Shield Roofing, we recognize that many Myrtle Beach homes have flat roof sections that benefit enormously from TPO membrane systems.

While TPO is primarily known as a commercial roofing material, it provides exceptional value for numerous residential applications. Many Myrtle Beach homes include flat or low-slope roof sections that traditional shingles cannot properly protect. TPO offers homeowners the same benefits commercial buildings enjoy—superior waterproofing, energy efficiency, and longevity.

Sunrooms and Florida Rooms

Sunrooms are extremely popular in Myrtle Beach, providing additional living space that connects indoor and outdoor environments. Most sunrooms feature flat or low-slope roofs that are poorly suited for shingles. TPO is the ideal sunroom roofing solution because the white membrane reflects heat, keeping sunrooms comfortable without excessive AC; heat-welded seams prevent leaks that damage interior finishes; the material handles thermal expansion from temperature swings; and it's compatible with skylights and glass panel installations. We have re-roofed hundreds of sunrooms throughout the Grand Strand, replacing failed shingles and built-up roofing with durable TPO membranes.

Carports and Porte-Cocheres

Attached carports protect vehicles from sun damage and rain, but their flat roofs require appropriate roofing materials. TPO provides watertight protection that prevents rust damage to vehicles below, reflects heat to keep covered areas cooler, handles foot traffic if access is needed, and lasts 20-30 years with minimal maintenance. Detached carports and garage additions with flat roof sections also benefit from TPO installation.

Garage Roof Sections

Many Myrtle Beach homes feature attached garages with flat roof sections, either as original construction or later additions. These areas often develop leaks when conventional roofing materials fail on low slopes. TPO provides proper waterproofing for slopes as low as 0.25:12 (essentially flat), eliminating the persistent leaks that plague garage roof sections. The energy efficiency also helps keep garage spaces cooler in summer.

Home Additions and Extensions

When adding space to existing homes, flat roofs often provide the most practical construction approach. Whether extending a kitchen, adding a master suite, or creating a bonus room, TPO roofing ensures the new space remains dry and energy-efficient. We coordinate with general contractors throughout the Myrtle Beach area on home addition projects requiring flat roofing expertise.

Porch and Patio Roof Covers

Covered porches and patios extend outdoor living seasons, but require roofing that handles direct sun exposure and heavy rain. TPO keeps covered areas cooler while providing watertight protection. The clean white appearance complements modern architectural styles, and the material resists mold and mildew growth common in shaded, humid areas.

Pool Houses and Outdoor Structures

Pool houses, outdoor kitchens, and accessory structures often feature flat roofs that benefit from TPO installation. The material resists pool chemical exposure, handles constant humidity, and maintains appearance despite direct sun exposure. Many Myrtle Beach waterfront properties include multiple structures that we protect with coordinated TPO roofing systems.

Modern Architectural Homes

Contemporary home designs increasingly feature flat roof sections as architectural elements. These modern aesthetic choices require roofing materials that perform reliably while maintaining clean visual lines. TPO provides the watertight performance these designs demand while complementing modern architecture with its sleek white appearance. We work with architects and builders throughout Myrtle Beach on new construction projects featuring flat roof designs.

TPO Energy Efficiency: Reducing Cooling Costs in Myrtle Beach

Energy efficiency represents one of TPO roofing's most compelling advantages for Myrtle Beach property owners. In a region where air conditioning accounts for 40-50% of commercial energy costs and runs 7+ months annually, the cooling cost reductions from TPO can total thousands of dollars each year.

The science is straightforward: white TPO membranes reflect 70-90% of solar radiation, compared to just 5-15% for dark asphalt shingles or black EPDM rubber roofing. This reflectivity keeps roof surface temperatures 50-60 degrees Fahrenheit cooler on hot summer days. Since roof temperature directly affects heat transfer into the building below, cooler roofs mean dramatically reduced air conditioning loads.

Typical Energy ROI Period

Building owners typically see 25-40% reduction in cooling costs after installing TPO roofing, with the exact savings depending on insulation levels, building use, and HVAC efficiency. For a typical 10,000 square foot commercial building in Myrtle Beach spending $15,000 annually on cooling, TPO can save $4,000-6,000 per year. Over a 25-year roof lifespan, that totals $100,000-150,000 in energy savings alone.

TPO roofing qualifies for ENERGY STAR certification as a cool roofing material, and may be eligible for utility company rebates and federal tax incentives. The Inflation Reduction Act of 2022 extended and expanded tax credits for energy-efficient commercial building improvements, potentially including qualifying TPO roofing installations. We recommend consulting with your tax advisor regarding specific eligibility.

Beyond individual building benefits, TPO's reflectivity helps reduce the urban heat island effect that raises temperatures throughout developed areas. By reflecting solar radiation rather than absorbing and re-radiating it as heat, TPO roofs contribute to cooler communities and reduced regional cooling demand.

Hurricane and Wind Uplift Resistance for Coastal South Carolina

Hurricane preparedness is non-negotiable for Myrtle Beach property owners. With major hurricane strikes occurring regularly along the South Carolina coast, roofing systems must withstand extreme wind conditions. TPO roofing, when properly installed, provides exceptional hurricane resistance that protects buildings and their contents.

Understanding Wind Uplift

Wind damage to roofing occurs primarily through uplift—negative pressure created as wind flows over a building causes suction that can pull roofing materials off the deck. Flat roofs are particularly susceptible to wind uplift at edges, corners, and perimeters where pressure differentials are greatest. Proper TPO installation accounts for these high-stress zones through increased fastening density and enhanced attachment methods.

TPO Installation Methods for Hurricane Zones

Weather Shield Roofing employs installation methods specifically designed for coastal South Carolina's high-velocity hurricane zone requirements:

Fully Adhered Systems

The membrane is bonded directly to the insulation or substrate using specialized adhesives. This creates the highest wind uplift resistance as the entire roof surface resists wind forces, not just fastener points. Fully adhered TPO is recommended for high-rise buildings, oceanfront properties, and anywhere maximum wind resistance is required.

Mechanically Attached Systems

The membrane is secured to the deck using plates and fasteners, with heat-welded seams covering the attachment points. Fastener spacing is calculated based on building height, location, and specific wind zone requirements. Enhanced fastening patterns at edges and corners provide additional protection where wind forces are strongest.

Proven Hurricane Performance

During Hurricane Florence (2018), which made landfall near Wrightsville Beach as a Category 1 storm with sustained winds of 90 mph, properly installed TPO roofs throughout our service area sustained minimal damage. Similarly, Hurricane Dorian (2019) passed offshore as a Category 2 storm, producing tropical storm conditions along the Grand Strand. TPO roofs we had installed and maintained came through these events without significant failures, while many traditional roofing systems in the same areas experienced substantial damage.

These real-world results validate the laboratory testing and wind uplift ratings that TPO systems achieve. Factory Mutual (FM) and Underwriters Laboratories (UL) provide independent certification of wind uplift resistance, and we only install systems meeting or exceeding South Carolina coastal building code requirements.

Heat-Welded Seam Advantage

TPO's heat-welded seams provide critical protection during hurricanes. Unlike mechanically fastened seams or adhesive connections that can separate under wind stress, properly welded TPO seams create molecular bonds stronger than the membrane itself. Wind-driven rain cannot penetrate these continuous surfaces, protecting building interiors from water damage even in extreme conditions. After a storm passes, intact TPO roofs require only inspection and minor debris removal, allowing rapid return to normal operations.

TPO Roofing Lifespan in Coastal South Carolina

Quality TPO roofing systems provide 20-30 years of reliable service in Myrtle Beach when properly installed and maintained. Understanding the factors that affect TPO longevity helps property owners make informed decisions and maximize their roofing investment.

Factors Affecting TPO Lifespan

1

Membrane Thickness

TPO membranes are available in 45, 60, and 80 mil thicknesses. For coastal South Carolina applications, we recommend minimum 60 mil thickness, with 80 mil preferred for high-traffic areas and maximum longevity. Thicker membranes resist punctures, handle foot traffic better, and provide more material for UV exposure to degrade over time.

2

Installation Quality

Proper installation is the single most important factor in TPO longevity. Heat-welded seams must achieve complete fusion without overheating (which weakens the membrane) or underheating (which creates weak bonds). Flashing details around penetrations and edges require precision to prevent water infiltration. Weather Shield Roofing's certified installers undergo continuous training and quality control measures ensure every installation meets manufacturer specifications.

3

Maintenance Practices

Regular maintenance extends TPO lifespan significantly. Semi-annual inspections identify developing issues before they cause failures. Debris removal prevents punctures and drainage problems. Addressing minor repairs promptly prevents water infiltration that can compromise the roof system. Our maintenance programs document roof condition over time and ensure warranty requirements are met.

4

Environmental Exposure

Myrtle Beach's climate presents specific challenges: intense UV radiation degrades roofing materials over time; salt air can affect exposed metal components; high humidity promotes biological growth on surfaces; and hurricane impacts can cause physical damage. Quality TPO contains UV stabilizers and resists biological growth, but environmental exposure does affect long-term performance. Properties closest to the ocean may see slightly shorter lifespans than inland properties.

Warranty Coverage

Major TPO manufacturers offer warranties ranging from 15 to 30 years depending on system specifications and installation certification level. These warranties typically cover material defects and workmanship failures, with specific terms varying by manufacturer and product line. Weather Shield Roofing installs premium TPO systems from GAF, Carlisle, Firestone, and Johns Manville, providing access to their most comprehensive warranty programs.

In addition to manufacturer warranties, we provide our own workmanship warranty covering installation quality. Our warranty program ensures any issues arising from installation are addressed promptly at no cost to the property owner. Combined with manufacturer material warranties, this provides comprehensive protection for your TPO roofing investment.

TPO Roofing Installation Process

Understanding the installation process helps property owners prepare for their TPO roofing project and recognize quality workmanship.

1

Roof Assessment and Design

Every TPO installation begins with comprehensive assessment of the existing roof condition, deck structure, drainage patterns, and penetrations. We measure the roof accurately, identify any structural issues requiring repair, and design the TPO system including membrane layout, insulation specifications, and attachment methods. For re-roofing projects, we determine whether existing materials can remain or must be removed.

2

Surface Preparation

Proper surface preparation ensures TPO membrane adheres properly and performs as designed. For new construction, we verify deck condition and install appropriate substrate. For re-roofing, we remove existing materials if necessary, repair deck damage, and prepare a clean, smooth surface. Any structural repairs, drainage improvements, or penetration modifications occur during this phase.

3

Insulation Installation

Rigid insulation boards (typically polyisocyanurate or expanded polystyrene) are installed to achieve desired thermal performance. Insulation may be mechanically fastened or adhered depending on the overall system design. Board layout is staggered to eliminate thermal bridging at joints. For coastal applications, we typically recommend R-25 or higher insulation values to maximize energy efficiency benefits.

4

Membrane Installation

TPO membrane sheets are rolled out and positioned according to the installation plan. Sheets overlap by 6 inches minimum to allow for heat welding. For mechanically attached systems, membrane is secured with plates and fasteners at calculated intervals. For fully adhered systems, specialized adhesive is applied and membrane is rolled into place. All penetrations are wrapped with prefabricated or field-fabricated TPO flashing.

5

Heat Welding Seams

The critical step that distinguishes TPO from other single-ply membranes. Using specialized hot-air welding equipment operating at 900-1200 degrees Fahrenheit, installers fuse overlapping membrane edges into continuous, watertight seams. Proper welding technique creates bonds stronger than the membrane itself. Weld quality depends on temperature, speed, and pressure—factors our certified installers control precisely.

6

Flashing and Detail Work

All roof edges, penetrations, drains, and transitions receive appropriate flashing treatment. Prefabricated TPO accessories (pipe boots, inside/outside corners, scupper boxes) are heat-welded to create seamless waterproofing. Perimeter edges are secured with termination bars and sealant. This detail work requires precision—most roof failures occur at flashing points rather than field areas.

7

Quality Control and Final Inspection

Every installation includes comprehensive quality control. Seam probe testing verifies weld integrity throughout the roof. Visual inspection confirms proper flashing installation and membrane condition. Drainage testing ensures water flows to drains and scuppers as designed. We document the completed installation with photographs and provide property owners with maintenance guidelines and warranty information.

TPO Roofing Maintenance Requirements

TPO roofing requires significantly less maintenance than many traditional roofing systems, but regular care extends lifespan and ensures warranty compliance. Our recommended maintenance program keeps your TPO roof performing optimally throughout its service life.

Semi-Annual Inspections

Professional inspections in spring and fall identify developing issues before they cause failures. We check seam condition, flashing integrity, membrane surface, drainage function, and all penetration details. Inspection reports document roof condition over time and identify maintenance needs.

Debris Removal

Accumulated debris (leaves, branches, trash) can puncture membranes, block drains, and retain moisture. Regular clearing—especially after storms—prevents these issues. Avoid using sharp tools that could damage the membrane surface.

Drain Maintenance

Drains, scuppers, and gutters must remain clear for proper water removal. Clogged drainage causes ponding water that accelerates membrane degradation and increases structural load. Pre-hurricane season drain clearing is especially important in Myrtle Beach.

Post-Storm Inspection

After significant weather events (hurricanes, severe thunderstorms, hail), professional inspection identifies storm damage requiring repair. Prompt attention to storm damage prevents secondary water damage and maintains warranty coverage.

What to Avoid

  • xExcessive foot traffic - Walk only on designated paths or walk pads
  • xSharp objects - Never drag equipment across the membrane
  • xHarsh chemicals - Avoid petroleum-based solvents and cleaners
  • xPressure washing - High pressure can damage membrane surface
  • xUnauthorized modifications - New penetrations require professional installation

Frequently Asked Questions About TPO Roofing

Get answers to common questions about TPO roofing in Myrtle Beach.

What is TPO roofing and how does it work?
TPO (Thermoplastic Polyolefin) is a single-ply roofing membrane made from polypropylene and ethylene-propylene rubber polymerized together. The material comes in large sheets (typically 10, 12, or 20 feet wide) that are rolled onto the roof substrate and heat-welded at the seams using specialized hot-air welding equipment. This heat-welding process creates seams stronger than the membrane itself, making TPO exceptionally leak-resistant. The white reflective surface reflects up to 90% of solar radiation, dramatically reducing cooling costs. TPO has become the fastest-growing commercial roofing material in America due to its combination of affordability, durability, and energy efficiency.
How long does TPO roofing last in Myrtle Beach coastal climate?
Quality TPO roofing systems typically last 20-30 years in Myrtle Beach when properly installed and maintained. The coastal climate presents unique challenges including salt air, high humidity, intense UV exposure, and hurricane-force winds. However, TPO is specifically engineered to handle these conditions. The membrane contains UV stabilizers that prevent degradation from sun exposure, and heat-welded seams create watertight connections that withstand heavy coastal rain. With our recommended semi-annual inspections and maintenance program, many TPO roofs exceed their expected lifespan. The key factors affecting longevity are membrane thickness (we recommend 60-80 mil for coastal installations), proper installation techniques, and regular maintenance.
Is TPO roofing good for residential homes in South Carolina?
Yes, TPO is excellent for specific residential applications in South Carolina, though it is primarily designed for flat or low-slope roofs (0.25:12 to 3:12 pitch). TPO is ideal for: sunrooms and Florida room additions, attached and detached carports, garage roofs with flat sections, modern architectural homes with flat roof designs, porch and patio roof coverings, pool houses and outdoor structures, and home additions requiring flat roofing. While most Myrtle Beach homes have pitched roofs using shingles or metal, TPO provides superior protection for flat-roofed sections at a lower cost than other flat roofing options. The energy efficiency benefits are particularly valuable for sunrooms and enclosed porches.
What is the difference between TPO and EPDM rubber roofing?
TPO and EPDM are both single-ply membranes, but they differ significantly in composition, appearance, and performance. TPO is a thermoplastic with heat-welded seams, typically white or light gray, reflecting 70-90% of solar radiation. EPDM is synthetic rubber with glued or taped seams, black in color, absorbing heat. TPO seams are stronger than the membrane itself due to heat welding, while EPDM seams can separate over time. TPO costs slightly more ($5-8/sq ft vs $4-7/sq ft for EPDM) but offers better energy efficiency, reducing cooling costs 25-40% in hot climates. For Myrtle Beach, we generally recommend TPO for its superior heat reflection and seam strength, though EPDM remains viable for shaded areas or budget-conscious projects.
How does TPO compare to PVC roofing?
TPO and PVC are both white, heat-welded thermoplastic membranes with similar installation methods, but they have key differences. PVC contains plasticizers and chlorine, providing superior chemical resistance ideal for restaurants, industrial facilities, and buildings with rooftop grease exhausts. TPO does not contain chlorine, making it more environmentally friendly and typically 10-20% less expensive. PVC has a longer track record (50+ years) while TPO is newer (30+ years). Both perform excellently in coastal South Carolina. We recommend PVC for commercial kitchens, manufacturing plants, and buildings with chemical exposure. TPO is ideal for most other applications where cost-effectiveness and environmental considerations are priorities.
Can TPO roofing withstand hurricanes in Myrtle Beach?
Yes, properly installed TPO roofing systems provide excellent hurricane resistance. TPO membranes can be mechanically fastened or fully adhered, both methods achieving wind uplift ratings exceeding 120 mph when installed to manufacturer specifications. Fully adhered systems offer the highest wind resistance, suitable for South Carolina coastal high-velocity hurricane zones. Heat-welded seams create continuous membrane surfaces with no gaps for wind to penetrate. During Hurricane Florence (2018) and Hurricane Dorian (2019), properly installed TPO roofs in our service area sustained minimal damage while many shingle roofs failed. We follow Factory Mutual (FM) and UL wind uplift standards, ensuring your TPO roof meets or exceeds South Carolina coastal building codes.
How much does TPO roofing installation cost in Myrtle Beach?
TPO roofing in Myrtle Beach typically costs $5-10 per square foot installed, depending on project complexity, membrane thickness, and installation method. For a 2,000 square foot commercial building, expect $10,000-$20,000 total cost. For a residential sunroom or carport (200-500 sq ft), costs range from $1,500-$5,000. Factors affecting price include: membrane thickness (50, 60, or 80 mil), installation method (mechanically attached vs fully adhered), insulation requirements and R-value needs, existing roof removal and disposal, flashings, penetrations, and detail work, and accessibility and building height. We provide detailed written estimates with itemized costs. While TPO costs more than some alternatives upfront, the energy savings (25-40% reduction in cooling costs) often offset the initial investment within 5-7 years.
What maintenance does a TPO roof require?
TPO roofing requires minimal maintenance compared to other roofing systems, but regular care extends its lifespan significantly. We recommend: semi-annual inspections (spring and fall) to check seams, flashings, and membrane condition; debris removal to prevent punctures and drainage issues; clearing drains and scuppers before hurricane season; inspecting after major storms for damage; and professional cleaning every 2-3 years to maintain reflectivity. Avoid walking on TPO roofs unnecessarily, place walk pads in high-traffic areas, and never use harsh chemicals or pressure washers. Our preventive maintenance program includes documented inspections, minor repairs, and emergency priority service, typically costing $200-400 annually depending on roof size.
Is TPO roofing energy efficient?
TPO is one of the most energy-efficient roofing materials available. White TPO membranes reflect up to 90% of solar radiation (compared to 5-15% for dark asphalt shingles), reducing roof surface temperatures by 50-60 degrees Fahrenheit on hot summer days. This dramatically reduces heat transfer into the building, cutting air conditioning costs by 25-40% depending on insulation levels and building design. TPO roofing qualifies for ENERGY STAR certification and may be eligible for utility rebates and federal tax incentives. In Myrtle Beach with 7+ months of cooling season, a TPO roof on a commercial building can save thousands of dollars annually in energy costs. The reflective properties also reduce the urban heat island effect, benefiting the broader community.
How is TPO roofing installed?
TPO installation follows a precise multi-step process: First, the existing roof is assessed and removed if necessary, then the deck is inspected and repaired. A vapor retarder may be installed depending on building use. Rigid insulation boards (polyiso or EPS) are mechanically fastened or adhered to achieve desired R-value. TPO membrane sheets are rolled out and positioned with proper overlaps (typically 6 inches). Seams are heat-welded using hot-air welding guns at temperatures between 900-1200 degrees Fahrenheit, creating bonds stronger than the membrane itself. All penetrations (vents, pipes, HVAC units) receive custom-fabricated flashing. Perimeter edges are secured with termination bars and sealant. Quality control includes seam probing to verify weld integrity. A professional installation typically takes 1-3 days for residential applications and 1-2 weeks for commercial buildings.
