Frequently Asked Questions: Single-Ply Roofing

You may already have encountered single-ply membrane as one of several potential commercial roofing systems. If you’re unfamiliar with this increasingly popular roofing option, Harmony Home Improvement answers frequently asked questions about it.

QUESTION: What Are the Types of Single-Ply Roofing?

There are several options available today, the most popular of which are TPO (thermoplastic polyolefin), PVC (polyvinyl chloride) and EPDM (ethylene propylene diene monomer). The latter is often referred to as rubber roofing, while the others are known as plastic roofing. Unlike traditional built-up roofing systems, these single-ply materials are installed as a single layer of material on the substrate.

QUESTION: How Are These Materials Installed on a Commercial Roof?

Commercial roofing contractors can install single-ply roofing in several ways, depending on factors such as cost, timeframe and purpose. It can be fully adhered, using a combination of heat-welding and adhesive, which results in a rigid installation that is best against high winds and foot traffic. This takes the longest to finish as adhesives need time to cure. Mechanically fastened roofing uses manufacturer-approved fasteners and is ready for use right after installation. The loose-laid method is secured only at the roofing perimeters and penetrations, while the rest of the roof area is weighted down.

QUESTION: What’s the Typical Life Span of Single-Ply Roofing?

Several factors affect roof life span, such as wind conditions, foot traffic and installation quality. Having said that, single-ply roofing usually lasts for 20 years or so with proper care and maintenance.

QUESTION: Can Single-Ply Roofing Be Repaired?

Just like every modern roofing system, yes. The methods differ depending on your chosen system, but punctures can be effectively repaired using manufacturer-approved patches or sealants. It’s important to have punctured or torn parts repaired as soon as possible to avoid rainwater intrusion or getting torn off by wind.

QUESTION: Is Single-Ply Roofing Energy-Efficient?

Most single-ply roofing systems are available in white, so, yes. Basically, white roofing reflects sunlight, which reduces the amount of heat absorbed through the roof. This helps reduce your commercial property’s indoor cooling requirements, resulting in energy savings.
