What is Roof Membrane Replacement?

Roof membrane replacement involves removing your existing flat or low-slope roofing system and installing a new, high-quality single-ply membrane. Unlike traditional shingle roofs, membrane roofing creates a continuous waterproof barrier that's specifically engineered for flat and low-slope applications.

Modern membrane systems—including TPO, PVC, and EPDM—offer superior waterproofing, energy efficiency, and longevity compared to older built-up or modified bitumen systems. When properly installed by certified professionals, these membranes provide 20-30 years of reliable protection.

Quality Matters: The difference between a 15-year roof and a 30-year roof often comes down to membrane quality and installation expertise. We only install premium-grade membranes with proper heat-welded seams and manufacturer-certified techniques.

Membrane Replacement FAQs

Answers to the most common questions about high-quality roof membrane replacement.

What makes a roof membrane "high quality"?

High quality roof membranes are characterized by superior thickness (60 mil+ for TPO/PVC, 60-90 mil for EPDM), reinforced construction with polyester or fiberglass scrim, heat-welded seams rather than adhesive tape, UV-resistant formulations, and manufacturer warranties of 20+ years. We only install premium membranes from trusted manufacturers like GAF, Carlisle, Firestone, and Johns Manville that meet these standards.

How long does roof membrane replacement take?

Most residential flat roof membrane replacements take 2-4 days. Commercial projects typically range from 1-3 weeks depending on size. A 10,000 sq ft commercial building usually completes in 5-10 working days. We minimize business disruption with flexible scheduling and can work weekends if needed.

Which membrane type is best for coastal areas like Myrtle Beach?

For coastal South Carolina, we typically recommend TPO or PVC membranes. Both resist salt-air corrosion, provide excellent UV resistance, and can be installed with enhanced wind uplift ratings for hurricane zones. White reflective surfaces also significantly reduce cooling costs in our hot climate. PVC is ideal if your building has rooftop equipment with grease or chemical exposure.

How do membrane roofs perform in hurricanes?

Modern membrane roofing systems can meet Miami-Dade hurricane requirements when properly installed. We use mechanically attached or fully adhered installation methods with enhanced fastener patterns for high-wind zones. Our systems are rated for 150+ mph winds. Proper edge termination and seam strength are critical—areas where our certified installers excel.

Can you install a new membrane over my existing roof?

Sometimes yes—this is called a "recover" or "overlay" and saves 20-30% by avoiding tear-off costs. However, recover is only appropriate when: the existing roof has one layer, no moisture damage exists, structural capacity permits additional weight, and local codes allow it. We take core samples to determine if recover is viable for your specific roof.

What warranties come with membrane replacement?

Quality membrane replacement includes two warranties: The manufacturer warranty covers material defects (typically 20-30 years for premium systems). Our workmanship warranty covers installation quality—Weather Shield Roofing provides a lifetime workmanship warranty. As GAF Preferred Contractors, we can offer NDL (No Dollar Limit) warranties that provide the most comprehensive coverage available.

How do I know if I need replacement vs. repair?

Consider replacement when: repairs exceed 30% of replacement cost, the membrane is beyond 80% of expected lifespan, you have multiple leaks despite repairs, significant ponding water exists, or widespread membrane shrinkage is present. Repair makes sense for localized damage on newer roofs, minor seam issues, or single penetration leaks. Our free inspection helps you make the most cost-effective decision.

Do white membrane roofs really save energy?

Absolutely. White TPO and PVC roofs reflect 70-85% of solar energy compared to 5-15% for dark roofs. This reduces rooftop surface temperatures by 50-80°F, translating to 25-40% cooling cost reduction for buildings with significant flat roof area. ENERGY STAR certified systems may qualify for utility rebates. In Myrtle Beach's hot climate, reflective membranes typically pay for themselves through energy savings within 5-10 years.
