What is EPDM Roofing?
EPDM (Ethylene Propylene Diene Monomer) is a high-performance synthetic rubber roofing membrane that has been protecting commercial and residential buildings for over 50 years. Often called "rubber roofing," EPDM is one of the most trusted and widely-used flat roofing systems in the United States, with billions of square feet installed on buildings ranging from small residential additions to massive industrial facilities.
The EPDM membrane is manufactured from a combination of ethylene and propylene (derived from oil and natural gas) along with a small amount of diene monomer that enables cross-linking during the curing process. This creates an extremely durable, flexible, and weather-resistant material that outperforms many other roofing options in terms of longevity and reliability.
For Myrtle Beach property owners with flat or low-slope roofs, EPDM offers an exceptional combination of proven performance, affordability, and ease of maintenance. Whether you manage a commercial building, own a home with a flat-roof section, or need to protect an addition, garage, or porch, EPDM rubber roofing delivers reliable protection against South Carolina's challenging coastal climate.
Key Characteristics of EPDM Roofing
- 1.Exceptional Flexibility: EPDM remains flexible across a wide temperature range (-40F to +300F), allowing it to expand and contract with building movement without cracking or splitting.
- 2.UV and Ozone Resistance: The rubber compound naturally resists degradation from ultraviolet radiation and atmospheric ozone, two factors that destroy many other roofing materials.
- 3.Waterproof Membrane: EPDM is inherently waterproof and, when properly installed, creates a seamless barrier against water infiltration.
- 4.Chemical Stability: Unlike PVC or some thermoplastic membranes, EPDM contains no plasticizers that can leach out over time, ensuring consistent performance throughout its lifespan.
- 5.Proven Track Record: With over five decades of real-world performance data, EPDM has the longest track record of any single-ply roofing membrane.
Benefits of EPDM Roofing for Myrtle Beach Climate
Myrtle Beach presents unique roofing challenges that EPDM is specifically equipped to handle. Our coastal environment tests roofing materials with intense UV exposure, high humidity, salt air, and severe weather events.
Superior UV Resistance
Myrtle Beach receives approximately 215 sunny days per year, subjecting roofs to intense ultraviolet radiation. EPDM's molecular structure naturally resists UV degradation without requiring additional coatings or treatments. While other roofing materials become brittle and crack under constant sun exposure, EPDM maintains its flexibility and integrity for decades.
Humidity & Moisture Performance
With average humidity levels of 70-80% along the Grand Strand, moisture management is critical. EPDM is completely waterproof and does not absorb water. Unlike organic-based materials that can support mold and mildew growth, EPDM's synthetic rubber composition resists biological growth, keeping your roof clean and functional in our humid environment.
Salt Air Tolerance
Properties near the ocean face constant exposure to salt-laden air that corrodes metal and degrades many roofing materials. EPDM rubber is chemically inert to salt and does not corrode or deteriorate from salt exposure. This makes it an excellent choice for oceanfront commercial properties and beach homes in Cherry Grove, Surfside Beach, and Garden City.
Temperature Flexibility
South Carolina experiences temperature swings from freezing winter nights to 100F+ summer days. EPDM remains flexible across this entire range, expanding and contracting with the building without splitting or developing stress cracks. Materials that become rigid in cold weather often fail at seams and edges; EPDM does not.
Storm & Wind Resistance
Hurricane season brings high winds and driving rain to the Myrtle Beach area. Fully-adhered EPDM systems bond directly to the roof deck, creating a monolithic membrane that resists wind uplift. When properly installed with FM-approved adhesives, EPDM withstands sustained winds exceeding 120 mph, providing reliable protection during coastal storms.
Ponding Water Tolerance
Flat roofs may experience temporary water ponding after heavy rains, common during Myrtle Beach's summer thunderstorms. EPDM tolerates ponding water better than many roofing materials, maintaining its waterproof integrity even when water sits on the surface for extended periods. This gives property owners peace of mind during intense rainfall events.
EPDM vs Other Flat Roofing Materials
Understanding how EPDM compares to alternative flat roofing systems helps property owners make informed decisions. Each material has strengths for specific applications.
| Feature | EPDM | TPO | PVC | Modified Bitumen |
|---|---|---|---|---|
| Track Record | 50+ years | 25 years | 40 years | 40 years |
| Expected Lifespan | 25-30+ years | 15-25 years | 20-30 years | 15-20 years |
| Installation Cost | Lower | Moderate | Higher | Moderate |
| UV Resistance | Excellent | Good | Good | Moderate |
| Flexibility in Cold | Excellent | Moderate | Good | Poor |
| Chemical Resistance | Moderate | Good | Excellent | Good |
| Energy Efficiency | Moderate (black) | Excellent (white) | Excellent (white) | Poor |
| Repair Ease | Very Easy | Moderate | Moderate | Easy |
EPDM vs TPO Roofing
TPO (Thermoplastic Polyolefin) is a newer membrane that has gained popularity for its white reflective surface and heat-welded seams. However, TPO has only about 25 years of field experience compared to EPDM's 50+ years. Early TPO formulations had durability issues, and while manufacturers have improved the product, its long-term coastal performance remains less proven than EPDM.
Choose EPDM over TPO when: You prioritize proven longevity, lower installation cost, easier repairs, and flexibility in temperature extremes. Choose TPO when maximum energy efficiency (cool roof) is the primary concern.
EPDM vs PVC Roofing
PVC (Polyvinyl Chloride) roofing offers excellent chemical resistance and energy efficiency with its white surface. However, PVC typically costs 20-30% more than EPDM and requires heat-welded seams that demand specialized equipment and training. PVC membranes also contain plasticizers that can leach out over time, potentially reducing flexibility.
Choose EPDM over PVC when: Budget is a concern, the roof won't be exposed to grease or chemicals (like restaurant ventilation), and you want a material with stable long-term properties.
EPDM vs Modified Bitumen
Modified bitumen (mod-bit) is an asphalt-based multi-layer system that provides good waterproofing and puncture resistance. However, mod-bit requires torch application or hot asphalt (fire risk), has a shorter lifespan (15-20 years), and performs poorly in extreme cold. The black surface absorbs significant heat, increasing cooling costs.
Choose EPDM over Modified Bitumen when: You want longer lifespan, safer installation (no open flame), better flexibility, and easier repairs.
When to Choose EPDM
EPDM is typically the best choice for Myrtle Beach properties when:
- ✓ Long-term durability is the priority
- ✓ Budget optimization matters
- ✓ The roof requires periodic access/foot traffic
- ✓ Easy future repairs are important
- ✓ The building experiences temperature fluctuations
- ✓ A proven track record provides peace of mind
Commercial EPDM Roofing Applications
EPDM is the workhorse of commercial flat roofing, protecting millions of square feet of business, industrial, and institutional buildings across the Grand Strand.
Retail & Shopping Centers
Strip malls, shopping plazas, and big-box retailers throughout Myrtle Beach rely on EPDM for cost-effective, long-lasting roof protection. Large roof areas benefit from EPDM's quick installation and minimal maintenance requirements.
Office Buildings
Professional office spaces need reliable roofing that won't disrupt business operations. EPDM provides decades of leak-free performance with minimal maintenance, protecting valuable equipment and creating comfortable work environments.

Commercial buyer guide
When EPDM is the Right Rubber Roof for a Myrtle Beach Business
A commercial EPDM roof is not won by membrane choice alone. The right decision comes from the building use, drainage, rooftop equipment, storm exposure, access, insulation condition, and how much disruption the business can tolerate during the work.
Choose EPDM when
- The roof is a retail, office, warehouse, condo, medical, or storage building with ordinary rooftop exposure.
- Long service life, easier repairs, and a proven membrane are more important than a highly reflective white surface.
- The roof has many penetrations that need reliable flashing and future service access.
- The owner wants a clear repair-versus-replacement decision before committing capital.
Compare another system when
- The roof sits over a restaurant kitchen or heavy grease exhaust path where PVC may be a better chemical-resistance fit.
- The main goal is reducing summer cooling load with a white reflective membrane.
- Drainage is so poor that water management must be redesigned before any membrane decision matters.
- The roof is a candidate for coating, restoration, or targeted repair instead of full replacement.
Do not approve a thin bid
- Membrane thickness and attachment method should be named.
- Wet insulation and deck repair assumptions should be clear.
- Drains, scuppers, edge metal, curbs, and pipe penetrations should be scoped.
- Staging, access, work hours, warranty, and cleanup should be written.
EPDM Fit Matrix for Myrtle Beach Commercial Buildings
Competitor pages often list EPDM, TPO, and PVC without helping the owner decide. WeatherShield makes the recommendation from the roof use first: where the building sits, how water leaves the roof, what equipment is on top, and what the business cannot afford to interrupt.
Strong EPDM candidate
Warehouse, storage, office, or inland retail
Large roof area, normal rooftop exposure, lower grease risk, and a need for a proven repairable membrane make EPDM a practical commercial option.
Compare PVC before choosing EPDM
Restaurant, commercial kitchen, or heavy exhaust path
Grease, oils, and chemical exposure can change the best membrane. These roofs need curb, exhaust, and cleaning details reviewed before EPDM is approved.
Scope disruption before membrane
Hotel, resort, condo, or tenant-occupied property
Guest access, tenant parking, rooftop equipment, noise, odor, staging, and phased work can matter as much as membrane selection.
Attachment and edge details decide the roof
Oceanfront or high-wind exposed property
Fully adhered membrane, perimeter fastening, edge metal, parapet terminations, drains, scuppers, and storm inspection plans must be written into the scope.
Better commercial comparison path
If the roof is not an obvious EPDM fit, compare the full commercial system before signing a thin bid: membrane choice, attachment, wind-uplift detailing, insulation, drainage, deck repair allowances, access, warranty, and storm maintenance.
What WeatherShield checks before recommending EPDM
The inspection should protect the owner from buying the wrong roof. On commercial properties, the costly surprises are often hidden under old membrane, around drains, at parapet walls, and below rooftop units.
Roof slope, ponding water, drains, scuppers, and overflow paths
Open seams, punctures, shrinkage, edge pullback, and failed termination bars
HVAC curbs, pipe boots, restaurant exhaust curbs, skylights, and parapet flashing
Wet insulation, soft decking, fastener backing-out, and prior patch quality
Access for lifts, dumpsters, delivery, guest parking, and after-hours work
Warranty path, maintenance needs, and whether repair, coating, or replacement wins
Use the supporting WeatherShield hubs
EPDM decisions connect to the larger flat-roof and commercial roofing system. These pages help owners compare scope before requesting a written inspection.
Residential EPDM Roofing Applications
While often associated with commercial buildings, EPDM is an excellent solution for many residential flat roof applications in Myrtle Beach homes.
Home Additions & Extensions
Many Myrtle Beach homeowners add rooms, sunrooms, or living space with flat or low-slope roofs that don't match the main roof pitch. EPDM provides reliable waterproofing for these additions at a fraction of the cost of custom sloped roofing solutions.
Common applications: Family room additions, master suite extensions, home office spaces, attached workshops.
Porches & Covered Patios
Screened porches and covered patios are essential for enjoying Myrtle Beach's outdoor lifestyle while escaping the sun and rain. EPDM roofing protects these outdoor living spaces effectively, handling the transition between indoor and outdoor environments.
Common applications: Three-season rooms, screened porches, covered decks, outdoor kitchens.
Garages & Carports
Detached garages, workshop buildings, and carports often feature flat or low-slope roofs. EPDM provides durable, affordable protection for these structures, keeping vehicles and equipment dry without requiring expensive roofing systems.
Common applications: Detached garages, carports, boat storage, RV covers, workshops.
Modern & Contemporary Homes
Modern architectural designs often incorporate flat roof sections for aesthetic appeal. EPDM provides the waterproofing these designs require while maintaining clean, minimalist lines. The membrane is virtually invisible from ground level.
Common applications: Architectural flat roofs, rooftop decks (with proper walkway systems), modern beach homes.
Why Homeowners Choose EPDM
Affordable Quality
EPDM costs less than most alternatives while providing excellent long-term performance. Budget-conscious homeowners get professional-grade protection without premium pricing.
DIY-Friendly Repairs
Small EPDM repairs can be handled by handy homeowners using readily available patch kits. This reduces long-term maintenance costs and provides peace of mind.
Quiet Performance
Unlike metal roofing, EPDM produces virtually no noise during rain or hail. This makes it ideal for living spaces where sound transfer would be disruptive.
EPDM Lifespan in Coastal South Carolina
One of the most common questions property owners ask is "How long will an EPDM roof last in Myrtle Beach?" The answer depends on several factors, but properly installed and maintained EPDM roofing typically provides 25-30 years of reliable service in our coastal environment, with many roofs exceeding 40 years.
Factors Affecting EPDM Lifespan
1. Membrane Thickness
EPDM is available in 45-mil and 60-mil thicknesses. For Myrtle Beach applications, we strongly recommend 60-mil membrane. The thicker material provides significantly better puncture resistance, durability, and longevity. While 45-mil costs less initially, 60-mil offers better long-term value, especially in coastal environments with storm debris exposure.
2. Installation Quality
The most critical factor in EPDM longevity is installation quality. Properly prepared surfaces, correct adhesive application, appropriate seam treatment, and attention to flashing details determine whether an EPDM roof lasts 15 years or 35+ years. This is why choosing an experienced, certified EPDM installer matters tremendously.
3. Installation Method
Three primary EPDM installation methods exist: fully-adhered, mechanically-attached, and ballasted. For coastal South Carolina, fully-adhered systems provide the best hurricane resistance and longest lifespan. Mechanically-attached systems work well for large commercial roofs. Ballasted systems (held down with gravel) are not recommended for hurricane-prone areas due to wind-blown gravel risk.
4. Maintenance Practices
Regular maintenance extends EPDM lifespan significantly. Annual inspections, keeping drains clear, removing debris accumulation, and addressing minor issues before they become major problems all contribute to longevity. Neglected EPDM roofs fail prematurely; well-maintained roofs exceed expectations.
5. Foot Traffic Exposure
Roofs that experience regular foot traffic (HVAC maintenance, solar panel service, etc.) need appropriate walkway protection. Unprotected EPDM can be damaged by repeated foot traffic. Walk pads or designated walkways extend membrane life in high-traffic areas.
EPDM Lifespan Expectations by Application
Commercial buildings with regular maintenance
Residential applications with minimal foot traffic
Well-maintained roofs with optimal conditions
EPDM Roofing Installation Process
Professional EPDM installation follows a proven process that ensures long-term performance. Here's what to expect when WeatherShield Roofing installs your EPDM roof.
Inspection & Assessment
We thoroughly inspect the existing roof structure, identify any deck damage or deterioration, assess drainage, and determine the optimal installation method for your specific building. This evaluation informs material selection and project planning.
Surface Preparation
Old roofing materials are removed if necessary. The deck is cleaned, dried, and repaired. Any deteriorated decking is replaced. For recover applications, existing roofing may be left in place if conditions permit.
Insulation Installation
If required, new insulation board is installed to improve energy efficiency. Insulation also creates a smooth, stable surface for the EPDM membrane and helps control condensation. Tapered insulation can improve drainage.
Membrane Positioning
Large EPDM sheets (up to 50 feet wide) are carefully positioned on the roof. Factory-fabricated membranes minimize field seams. The membrane is loosely laid and adjusted to ensure proper coverage and positioning before attachment.
Adhesion/Attachment
For fully-adhered systems, bonding adhesive is applied to both the membrane and substrate. The membrane is then carefully rolled into the adhesive, ensuring full contact without air pockets. Mechanically-attached systems use fasteners at designated intervals.
Seam Treatment
Where membrane sheets overlap, seams are treated with seam primer and covered with 6-inch seam tape, creating a watertight bond. Proper seam treatment is critical; most EPDM failures occur at inadequately sealed seams.
Flashing Installation
All penetrations (pipes, vents, HVAC curbs) and terminations (walls, parapets, edges) receive custom flashing using EPDM flashing material. Pipe boots, inside/outside corners, and edge details are carefully sealed.
Edge Termination
Roof edges receive appropriate termination treatment using drip edge, coping, or termination bars depending on edge type. Proper edge detail prevents wind uplift and water infiltration at the roof perimeter.
Final Inspection
Every seam, flashing, and termination is inspected for proper installation. Water testing may be performed on critical areas. We walk through the completed project with you, explain maintenance requirements, and provide warranty documentation.
EPDM Repair and Maintenance
One of EPDM's greatest advantages is its ease of repair. Unlike some roofing systems that require specialized equipment for repairs, most EPDM issues can be resolved quickly and cost-effectively.
Common EPDM Repairs
Puncture Repair
Small punctures from debris or foot traffic can be patched with EPDM patch tape or liquid rubber sealant. Most puncture repairs take minutes and cost very little.
Seam Re-adhesion
If seams begin to separate (usually due to original installation issues), they can be cleaned, primed, and re-sealed with seam tape or adhesive.
Flashing Repair
Deteriorated or damaged flashing around penetrations and edges can be replaced or reinforced with new EPDM flashing material and appropriate sealants.
Section Replacement
Larger damaged areas can have sections cut out and replaced with new EPDM, welded to the existing membrane. This is far less expensive than full replacement.
Maintenance Best Practices
Annual Inspections
Schedule professional inspections annually, ideally in spring after winter weather and before hurricane season. Early detection of issues prevents costly repairs.
Clear Drains Regularly
Keep roof drains, scuppers, and gutters clear of debris. Standing water from blocked drains accelerates membrane degradation and adds structural load.
Remove Debris
Remove leaves, branches, and accumulated debris promptly. Debris holds moisture against the membrane and can puncture EPDM during wind events.
Post-Storm Inspection
After significant storms or hurricanes, inspect for wind-blown debris damage, lifted edges, or flashing issues. Address problems promptly to prevent leaks.
WeatherShield EPDM Maintenance Program
We offer annual maintenance programs for commercial EPDM roofs that include comprehensive inspection, drain clearing, minor repairs, and detailed condition reporting. Proactive maintenance extends roof life and reduces emergency repair costs.
EPDM Roofing Cost Factors
EPDM roofing costs vary based on several project-specific factors. Understanding these variables helps property owners budget appropriately and compare quotes effectively.
We provide free, detailed estimates for EPDM repair, restoration, and replacement projects. For planning math before a site visit, use WeatherShield's roofing calculators and roof replacement cost estimator, then request a written commercial inspection for the real scope.
Roof Size & Complexity
Larger roofs benefit from economies of scale, reducing per-square-foot costs. Complex roofs with many penetrations, corners, and level changes require more labor and material for proper flashing.
Membrane Thickness
60-mil EPDM costs more than 45-mil but provides significantly better durability and longevity. For most applications, 60-mil offers better lifetime value despite higher upfront cost.
Installation Method
Fully-adhered systems cost more than mechanically-attached but provide superior wind resistance. For coastal Myrtle Beach, fully-adhered is often worth the additional investment.
Existing Roof Condition
Tear-off and disposal of existing roofing adds cost. If conditions permit, installing over existing roofing (recover) reduces expense. Deck repairs add to project cost.
Insulation Requirements
Adding or upgrading insulation improves energy efficiency but increases project cost. Building code requirements may mandate specific insulation R-values for commercial projects.
Access & Location
Difficult access (height, obstacles, limited staging area) increases labor costs. Urban locations with parking/delivery challenges may incur additional logistics costs.

EPDM Hurricane and Wind Resistance
Living in coastal South Carolina means preparing for hurricanes. EPDM roofing provides excellent wind resistance when properly installed using hurricane-rated systems and techniques.
Wind Resistance Features
- -Fully-Adhered Systems: EPDM bonded directly to the substrate creates a monolithic membrane with no loose edges for wind to catch. FM-approved adhesives withstand 120+ mph sustained winds.
- -Flexibility Under Stress: Unlike rigid materials that crack under wind stress, EPDM's flexibility allows it to absorb and distribute wind forces without failure.
- -Seamless Coverage: Large EPDM sheets (up to 50 ft wide) mean fewer seams where wind could cause lifting. Factory seams are stronger than field seams.
- -Debris Impact Resistance: 60-mil EPDM resists punctures from wind-blown debris better than thinner membranes or brittle materials.
Hurricane Preparation Tips
- -Pre-Season Inspection: Have your EPDM roof inspected before hurricane season begins. Address any seam issues, edge lifting, or flashing problems while conditions permit.
- -Clear Roof Debris: Remove any loose items from the roof that could become projectiles. Secure or remove rooftop equipment that isn't permanently anchored.
- -Check Drains: Ensure all roof drains are clear. Blocked drains during heavy hurricane rainfall can create dangerous ponding loads.
- -Post-Storm Assessment: After any hurricane or tropical storm, have your roof professionally inspected for damage that may not be visible from the ground.

Call WeatherShield for Emergency ServiceEPDM Roofing FAQs - Myrtle Beach
What is EPDM roofing and why is it good for Myrtle Beach?
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane roofing system ideal for flat and low-slope roofs. It excels in Myrtle Beach due to its exceptional UV resistance, waterproofing capability, and ability to handle temperature extremes. EPDM remains flexible in cold weather and resists heat degradation, making it perfect for South Carolina's variable climate.
How long does EPDM roofing last in coastal South Carolina?
EPDM roofing typically lasts 25-30 years in coastal South Carolina with proper installation and maintenance. Some well-maintained EPDM roofs have exceeded 40 years. The membrane's resistance to UV radiation, ozone, and weathering makes it particularly durable in our coastal environment.
Is EPDM roofing hurricane-resistant?
Yes, properly installed EPDM roofing offers excellent hurricane resistance. Fully-adhered EPDM systems with FM-approved adhesives can withstand winds exceeding 120 mph. The membrane's flexibility allows it to absorb wind stress without cracking or tearing, unlike rigid roofing materials.
Can EPDM be installed on residential homes in Myrtle Beach?
Absolutely. While EPDM is popular for commercial buildings, it's an excellent choice for residential flat roofs, porches, additions, garages, and sunrooms. Many Myrtle Beach homes with flat or low-slope sections benefit from EPDM's durability and cost-effectiveness.
How does EPDM compare to TPO and PVC roofing?
EPDM offers a longer track record (50+ years) and typically lower installation costs than TPO or PVC. TPO provides better energy efficiency with white reflective surfaces. PVC offers superior chemical resistance. For most Myrtle Beach applications, EPDM provides the best balance of cost, durability, and proven performance.
What maintenance does EPDM roofing require?
EPDM requires minimal maintenance: annual inspections, keeping drains clear, removing debris, and checking seams every 2-3 years. After major storms, inspect for punctures or lifted edges. With proper care, EPDM provides decades of trouble-free protection.
Can EPDM roofing be repaired if damaged?
Yes, EPDM is highly repairable. Small punctures and tears can be patched using EPDM repair tape or liquid rubber sealant. Larger damage may require patch pieces bonded with EPDM adhesive. Seam failures can be re-adhered or covered with seam tape. Most repairs can be completed in hours, not days.
Does EPDM roofing work with solar panels?
Yes, EPDM is compatible with solar panel installations. The membrane can accommodate penetrations when properly flashed, and ballasted solar systems work well on EPDM surfaces. Many Myrtle Beach commercial buildings combine EPDM roofing with solar arrays for energy efficiency.
What thickness of EPDM is best for Myrtle Beach?
For Myrtle Beach's coastal climate, we recommend 60-mil EPDM membrane for optimal durability and puncture resistance. While 45-mil works for budget applications, 60-mil provides significantly better longevity and is more resistant to foot traffic and debris impact during storms.
What should a commercial EPDM quote include?
A commercial EPDM quote should separate roof size, tear-off or recover plan, wet insulation, deck repairs, membrane thickness, attachment method, drainage corrections, rooftop equipment flashing, edge metal, warranty level, staging, and business-hour restrictions. If those line items are not clear, the proposal is hard to compare.
When is EPDM not the best commercial flat roof choice?
EPDM is not always the best choice for roofs with heavy grease exposure, frequent chemical exposure, poor drainage that cannot be corrected, or buildings where a highly reflective white membrane is the top energy priority. In those cases, PVC, TPO, coatings, or a different flat roof assembly may be a better fit.
Is EPDM better than TPO or PVC for a Myrtle Beach commercial roof?
EPDM can be the better fit for inland offices, warehouses, storage buildings, and budget-sensitive commercial roofs where proven service life and repairability matter most. TPO is often stronger when cooling load and a reflective white surface are the priority. PVC is usually stronger for restaurants, grease exposure, and some oceanfront chemical or salt-air conditions. WeatherShield compares building use, distance from the ocean, drainage, rooftop equipment, wind exposure, and repair history before recommending the membrane.
Can an EPDM roof be restored instead of replaced?
Sometimes. If the membrane is still bonded, seams and flashing can be repaired, wet insulation is limited, and drainage can be corrected, restoration or targeted repair may make sense. If the roof has widespread wet insulation, open seams, failing edges, structural deck damage, or repeated leaks, replacement is usually the safer business decision.
Is EPDM roofing environmentally friendly?
EPDM is one of the more environmentally friendly roofing options. It's 100% recyclable at end of life, contains no chlorine or plasticizers, and its long lifespan reduces landfill waste. Black EPDM can also absorb heat in winter, reducing heating costs during cooler months.
