Single Ply Roofing & Resealing: A Practical Guide for Gainesville Homeowners

If your home or building in Gainesville or the surrounding areas uses a single ply roofing system—like TPO, EPDM, or PVC—it’s vital to understand how it works and when it needs resealing. At L&L Roofing & Construction, we help property owners protect their investment through honest inspections, quality craftsmanship, and faith-driven service.

Here’s what you need to know.

What Is Single Ply Roofing?

Single ply roofing is a flat or low-slope roofing system made from durable, flexible membranes—usually TPO (thermoplastic polyolefin), EPDM (ethylene propylene diene terpolymer), or PVC (polyvinyl chloride).

These materials are commonly used on:

• Commercial buildings

• Garages

• Workshops

• Residential additions with low-slope roofs

Key Benefits:

• Lightweight and energy-efficient

• UV- and chemical-resistant

• Fast installation and cost-effective

• Reflective surfaces help lower cooling bills

But like any roofing material, single ply systems need regular maintenance—and eventually, resealing.

What Is Single Ply Resealing?

Over time, seams, flashings, and penetrations on a single ply roof can begin to degrade. Resealing involves applying a specialized coating or membrane sealant to restore waterproofing and extend roof life.

Why Reseal?

• Prevent leaks before they start

• Extend roof life by 5–15 years

• Avoid full roof replacement when unnecessary

• Improve energy efficiency by restoring reflectivity

Not all systems qualify for resealing, which is why a trustworthy inspection is step one.

When Should You Reseal a Single Ply Roof?

Our rule of thumb: reseal every 5–10 years, or whenever you see the following:

• Pooling water that takes more than 48 hours to drain

• Shrinkage or exposed seams

• Punctures, tears, or cracking near penetrations

• Loss of reflectivity (roof turns gray instead of bright white)

• Water stains inside your home or building

What Kind of Sealants Are Used?

At L&L Roofing, we only use commercial-grade products tested and approved by manufacturers like GAF, Mule-Hide, and Carlisle.

Options include:

• Acrylic-based coatings: Budget-friendly and UV-resistant

• Silicone coatings: Best for ponding water areas

• Polyurethane coatings: Durable and impact-resistant

We choose the right material for your roof type and weather exposure.

FAQs

How long does single ply resealing take?
Most resealing projects can be completed in 1–2 days, depending on size and weather.

Can I reseal a roof that already had a coating?
Yes, in many cases, we can recoat or repair the existing membrane—if it’s still structurally sound.

How much does resealing cost?
Costs vary based on material and square footage, but it’s significantly cheaper than full replacement. We'll give you a straightforward quote after inspection.

Is resealing covered by insurance?
If damage is due to hail or storms, resealing may be part of an approved insurance claim. We’ll help guide you through that process.
