Your Trusted Flat Roofing Contractor in Myrtle Beach

Finding a qualified flat roofing contractor near you is essential for protecting your commercial or residential investment. Flat roofs require specialized expertise that differs significantly from traditional pitched roofing. Weather Shield Roofing has served the Myrtle Beach area as a trusted flat roofing contractor, delivering expert installation, repair, and maintenance services for all flat and low-slope roofing systems.

Flat roofing systems demand precise installation techniques, proper drainage design, and materials specifically engineered for low-slope applications. Unlike pitched roofs that shed water by gravity, flat roofs rely on membrane waterproofing and properly designed drainage systems. A single installation error at a seam, flashing, or penetration can lead to persistent leaks and costly interior damage. That's why choosing an experienced flat roofing contractor matters.

Our flat roofing contractors are certified installers for industry-leading manufacturers including GAF, Carlisle, Firestone, and Johns Manville. This certification means we've undergone rigorous training, demonstrated proficiency in proper installation techniques, and meet ongoing quality standards. For you, it means access to the strongest material warranties and confidence that your flat roof is installed to manufacturer specifications.

Why Choose Weather Shield as Your Flat Roofing Contractor?

  • All Systems: TPO, EPDM, PVC, Mod Bit, BUR
  • Commercial & Residential: Projects of all sizes
  • Hurricane Rated: Coastal-grade installations
  • Free Inspections: No-obligation assessments
  • Local Expertise: Myrtle Beach climate specialists

Myrtle Beach's coastal environment presents unique challenges for flat roofing systems. High humidity promotes biological growth, salt air can degrade certain materials, intense UV radiation accelerates aging, and hurricane-force winds test every seam and connection. Our flat roofing contractors understand these local conditions and specify materials and installation methods proven to perform in coastal South Carolina.

Types of Flat Roofing Systems We Install

As a full-service flat roofing contractor, we install and maintain all major flat roofing systems. Each material offers distinct advantages depending on your building type, budget, and performance requirements.

TPO Roofing

Thermoplastic Polyolefin

20-30 years

The most popular commercial flat roofing material today. TPO white membranes reflect up to 90% of solar radiation, dramatically reducing cooling costs. Heat-welded seams create bonds stronger than the membrane itself, providing exceptional waterproofing and hurricane resistance. Available in 45, 60, and 80 mil thicknesses.

Best For: Commercial buildings, energy-conscious projects, hurricane zones

Modified Bitumen

Polymer-Modified Asphalt

15-20 years

Multi-layer asphalt system with polymer modifiers for enhanced flexibility and durability. Installed by torch application or self-adhesive sheets. The granulated cap sheet provides UV protection and slip resistance. More puncture-resistant than single-ply membranes.

Best For: Traditional commercial roofing, high-traffic areas, roof recovers

Residential Flat Roofing Contractor Services

Many Myrtle Beach homes include flat roof sections that require specialized expertise. Sunrooms, carports, garages, additions, and modern architectural designs all benefit from professional flat roofing installation.

While most homes feature pitched roofs, many Myrtle Beach properties include flat or low-slope sections that standard roofing contractors aren't equipped to handle properly. These areas often develop persistent leaks when covered with materials designed for steeper slopes. As a residential flat roofing contractor, we bring commercial-grade expertise to homeowner projects.

Common Residential Flat Roof Applications:

Sunrooms & Florida Rooms

TPO white membrane keeps sunrooms cooler while providing watertight protection. Ideal for temperature-sensitive spaces.

Carports & Porte-Cocheres

Protect vehicles from sun damage and rain with properly waterproofed flat roof coverings.

Garage Roof Sections

Many attached garages include flat sections that leak when covered with standard shingles. Membrane roofing solves the problem.

Home Additions

Kitchen extensions, master suite additions, and bonus rooms often require flat roofing for practical construction.

Porch & Patio Covers

Extend outdoor living with covered areas protected by durable flat roofing membranes.

Pool Houses & Outbuildings

Accessory structures benefit from flat roofing that handles humidity and direct sun exposure.

Modern Architectural Homes

Contemporary designs featuring flat roof elements require proper membrane installation for reliable performance.

Roof Decks & Terraces

Walkable flat roof areas require specialized membrane systems and proper drainage design.

Residential flat roof projects typically use TPO or EPDM membranes depending on visibility, energy efficiency priorities, and budget. Our residential flat roofing contractors treat every home project with the same attention to detail as commercial work, ensuring your flat roof sections perform reliably for decades.

Our Flat Roofing Installation Process

Quality flat roofing starts with proper planning and follows established procedures throughout installation.

1

Free Inspection & Assessment

Our flat roofing contractor inspects your existing roof, documents condition, identifies problem areas, and assesses structural adequacy. We measure the roof accurately and note all penetrations, drainage points, and access considerations.

2

System Design & Recommendation

Based on your building type, budget, and performance requirements, we recommend the optimal flat roofing system. Our proposal includes material specifications, installation method, insulation requirements, and warranty details.

3

Surface Preparation

Proper preparation ensures long-term performance. We remove existing materials (if required), repair deck damage, verify structural adequacy, and prepare a clean, smooth substrate for new membrane installation.

4

Insulation Installation

Rigid insulation boards provide thermal performance and create proper drainage slopes. Tapered insulation systems direct water toward drains, eliminating ponding. We achieve specified R-values while ensuring positive drainage.

5

Membrane Application

Our certified installers apply the selected membrane system following manufacturer specifications. For TPO and PVC, seams are heat-welded to create bonds stronger than the membrane itself. EPDM seams are adhered or taped per specifications.

6

Flashing & Detail Work

All edges, penetrations, curbs, and transitions receive proper flashing treatment. This detail work is where most flat roof failures occur, so we take extra care to ensure watertight connections at every point.

7

Quality Control & Final Inspection

Every installation includes seam testing, visual inspection, and drainage verification. We document the completed installation with photographs and provide maintenance guidelines and warranty information.

Why Myrtle Beach Needs Specialized Flat Roofing Contractors

Coastal South Carolina presents unique challenges that require flat roofing contractors with specific local expertise. Generic flat roofing approaches that work inland may fail prematurely in our demanding environment.

Hurricane Wind Resistance

Flat roofs face significant wind uplift during hurricanes. We install fully adhered systems and enhanced fastening patterns that meet coastal building codes and withstand 120+ mph winds.

Intense UV Exposure

Myrtle Beach averages 210+ sunny days annually. We specify membranes with advanced UV stabilizers and recommend white reflective surfaces that resist degradation and reduce cooling costs.

High Humidity & Rainfall

70-80% average humidity promotes biological growth. Our membrane selections resist mold and mildew. Proper drainage design handles heavy tropical rainfall without ponding.

Salt Air Corrosion

Proximity to the Atlantic means constant salt exposure. We use corrosion-resistant materials for all metal components and specify membranes proven in coastal environments.

Flat Roof Repair Contractor Services

Not every flat roof problem requires full replacement. As an experienced flat roof repair contractor, we diagnose issues accurately and provide cost-effective repair solutions when appropriate. Our goal is honest assessment and the most practical solution for your situation.

Common Flat Roof Repairs We Handle:

Seam Separation

Heat re-welding (TPO/PVC) or re-adhesion (EPDM) restores watertight seams.

Punctures & Tears

Membrane patches seal damage from foot traffic, falling debris, or equipment.

Flashing Failures

Re-flashing penetrations and edges eliminates leak points at details.

Ponding Water Correction

Tapered insulation additions or drainage improvements eliminate standing water.

Blistering & Bubbling

Addressing membrane separation prevents larger problems from developing.

Storm Damage Repair

Post-hurricane assessment and repair restores roof integrity quickly.

Repair vs. Replacement: Our Honest Assessment

We provide honest recommendations based on roof condition, age, and repair costs relative to replacement. General guidelines:

  • Repair:Localized damage on otherwise sound roofs, minor seam issues, single-point flashing failures, roofs with significant remaining lifespan.
  • Replace:Widespread membrane deterioration, multiple leak points, repair costs exceeding 30% of replacement cost, roofs past their expected lifespan.

During your free inspection, we document roof condition with photographs and provide clear recommendations with supporting rationale. You'll understand exactly why we recommend repair or replacement before making any decisions.

Flat Roofing Contractor FAQs

Get answers to common questions about flat roofing services in Myrtle Beach.

What types of flat roofing systems do you install?
Weather Shield Roofing installs all major flat roofing systems including TPO (Thermoplastic Polyolefin), EPDM (rubber membrane), Modified Bitumen, PVC membrane, and Built-Up Roofing (BUR). Each system has specific advantages depending on your building type, budget, and performance requirements. During your free consultation, we assess your property and recommend the optimal flat roofing system for your specific needs, whether commercial or residential.
How long does a flat roof last in Myrtle Beach?
Flat roof lifespan varies by material and maintenance. TPO roofing lasts 20-30 years, EPDM rubber roofing 20-25 years, Modified Bitumen 15-20 years, PVC membrane 25-30 years, and Built-Up Roofing 15-25 years. Myrtle Beach coastal conditions including salt air, high humidity, and hurricane exposure can affect longevity. Proper installation by a qualified flat roofing contractor and regular maintenance are essential to achieving maximum lifespan. We recommend semi-annual inspections and prompt repairs to extend your flat roof service life.
Do you work on both commercial and residential flat roofs?
Yes, Weather Shield Roofing serves both commercial and residential customers throughout the Myrtle Beach area. Commercial flat roofing projects include office buildings, retail centers, warehouses, restaurants, hotels, and industrial facilities. Residential flat roofing includes sunrooms, carports, garages, home additions, porches, modern architectural homes, and pool houses. We have the equipment, expertise, and crew size to handle projects ranging from small residential repairs to large commercial installations.
What is the best flat roofing material for Myrtle Beach climate?
For most Myrtle Beach applications, we recommend TPO (Thermoplastic Polyolefin) as the optimal flat roofing choice. TPO white membranes reflect up to 90% of solar radiation, reducing cooling costs significantly in our hot climate. Heat-welded seams provide superior waterproofing and hurricane resistance. For budget-conscious projects or shaded areas, EPDM rubber roofing offers excellent value. PVC is ideal for commercial kitchens and restaurants due to superior chemical resistance. Our flat roofing contractors will recommend the best material based on your specific building use and requirements.
How much does flat roof installation cost?
Flat roofing costs in Myrtle Beach typically range from $4-12 per square foot installed, depending on material selection, installation method, insulation requirements, and project complexity. EPDM is generally the most affordable option, while PVC and fully-adhered TPO systems cost more but offer superior performance. A 2,000 square foot commercial flat roof might range from $8,000 to $24,000 depending on specifications. Contact us for a free assessment and detailed estimate for your specific project. We provide transparent pricing with no hidden fees.
Can you repair my existing flat roof or does it need replacement?
Many flat roof issues can be repaired rather than requiring full replacement. Common flat roof repairs include seam separation, punctures, flashing failures, and ponding water correction. During our free inspection, we assess your flat roof condition, identify the root cause of any problems, and provide honest recommendations. If repairs will cost more than 30% of replacement value or the roof is beyond its useful life, we recommend replacement. We never recommend unnecessary work and will help you make an informed decision.
Do flat roofs leak more than pitched roofs?
Properly installed and maintained flat roofs do not leak more than pitched roofs. The key differences are that flat roofs rely on membrane waterproofing and drainage systems rather than gravity shedding. When a flat roofing contractor follows proper installation procedures including adequate slope (minimum 1/4 inch per foot), quality membrane application, proper flashing at all penetrations, and functional drainage, flat roofs perform reliably for decades. Most flat roof failures result from poor installation or deferred maintenance rather than inherent design flaws.
How do you prevent ponding water on flat roofs?
Ponding water (standing water that remains 48+ hours after rain) is the primary enemy of flat roofs. Prevention strategies include: installing tapered insulation systems to create positive drainage slopes, ensuring minimum 1/4 inch per foot slope toward drains, properly sizing and positioning roof drains and scuppers, installing overflow drainage as backup, keeping drains clear of debris, and addressing any structural sagging immediately. Our flat roofing contractors design drainage systems to eliminate ponding and extend roof lifespan.
Are flat roofs good for solar panel installation?
Yes, flat roofs are excellent for solar panel installation. The flat surface allows optimal panel positioning for maximum sun exposure, and panels can be oriented without concern for roof pitch limitations. TPO and PVC membranes are particularly compatible with ballasted (weighted) solar racking systems that avoid roof penetrations. We coordinate with solar installers to ensure membrane compatibility and proper flashing around any penetrations. Many commercial buildings choose flat roofs specifically because they simplify solar installation and maximize energy production.
What is the warranty on flat roof installation?
Flat roof warranties vary by material and manufacturer. TPO and PVC manufacturers offer 15-30 year material warranties depending on membrane thickness and system specifications. EPDM typically carries 15-25 year warranties. Modified Bitumen warranties range from 10-20 years. In addition to manufacturer warranties, Weather Shield Roofing provides our own workmanship warranty covering installation quality. We are certified installers for major manufacturers including GAF, Carlisle, Firestone, and Johns Manville, providing access to the strongest warranty programs available.
