What Is The Best Material For A Flat Roof?

Flat roofs are becoming predominant in high-end residential homes, thanks to the emerging roofing materials which offer both aesthetics and durability. To help you make an informed decision about the best flat roofing material for your home, here are a few options to consider.

1. Single-Ply Membranes

Single-Ply Membranes are sheets of synthetic materials or rubber which can be chemically adhered or ballasted to insulation to create a solid layer of protection for your property. There are two common types of single-ply roofing membranes: Ethylene Propylene Diene Terpolymer (EPDM) and Thermoplastic Polyolefin (TPO). They differ slightly in their chemical makeup, energy efficiency, and mode of application.

Overall, single-ply membrane roofing is highly regarded in terms of performance. TPO is fast growing in popularity since its generally manufactured white, which provides better UV reflection properties. EPDM, on the other hand, is a darker color membrane. However, this high-performance rubber compound offers excellent weather resistance and heat retention properties. Single-ply membrane roofing is also lightweight, which relieves the stress on your building’s structure. 

The only notable downside of single-ply membranes roofing is it can easily get punctured since it lacks a hard layer which protects the synthetic rubber from gravel, loose screws, or dropped tools. Seams may also be vulnerable to leaks when the roof is exposed to harsh UV rays for several years.

2. PVC Roofing

If you’re looking for a flat roofing material with unmatched durability, PVC tops the list. Known as Polyvinyl Chloride, PVC is a hard plastic material designed to withstand a lot. It’s also very reflective of sunlight which helps keep your building cool during the warmer months of the year.

The only downside of PVC roofing is the high price tag. While PVC is generally more expensive than EPDM and TPO, most roofing contractors will offer a lifetime warranty for the roofing system. The prefabrication of it offsite also helps to reduce the installation time, meaning lower labor costs and less interruption with your living arrangements.

3. Copolymer Alloy (CPA) 

Copolymer Alloy (CPA) is a thermoplastic material manufactured with no chemical crosslinking. This versatile roofing material can be repeatedly softened by applying heat or by hardened through cooling. Due to its chemical nature, CPA membranes are typically seamed through heat welding using hot air or solvent welding.
