A flat roof membrane is a modern roofing option commonly recommended for commercial buildings with almost level flat-roof slopes. The traditional route of asphalt coverage is now outdated, thanks to developments in roofing technology, with a flat roof membrane at the forefront of changing product options. Learn about this system and the specific advantages it has to offer.
What Is a Flat Roof Membrane?
A roofing membrane is a sheet made of a variety of compound materials, but most likely either synthetic rubber, thermoplastic or modified bitumen. Sheets of material are laid across the roof and bonded together with a specialized liquid adhesive, depending upon the specific material. Some types have the seams bonded using heat techniques or manufacturer-produced bonding tape. Roofing membranes must be installed by a professional contractor licensed to complete the work in order to maintain the warranty on most products. While they are most commonly used for commercial properties, their residential use is growing.
A membrane for a flat roof is more desirable than an asphalt coating partly because of the product’s longevity, but primarily because of its resistance to UV rays and extreme temperatures. Asphalt degrades quickly under UV exposure because the fluctuating temperatures cause the material to expand and contract. Synthetic flat roof membranes have a much higher level of flexibility. For this reason, the material is proven to last longer than asphalt coatings, without requiring reapplication on a regular basis. Install the membrane and schedule regular maintenance, but do not concern yourself with any other upkeep on it for 20 to 50 years, depending on the product selected.
Seamless Leak Protection
When the membrane sections are installed, the bonding process causes all of the seams to disappear on a chemical level. The membrane has no breaks in coverage like in asphalt roofing systems. It is difficult to find the exact location of a leak in an asphalt roofing system, and more difficult to fully repair, but this is not the case with a roofing membrane. If the membrane does spring a leak, a professional can quickly bond the material, eliminating the problem.
Purge Excess Weight
While older roofing systems require the use of heavy gravel to weigh down the material, hold them in place and guard against sunlight, roofing membranes are lightweight and sturdy all on their own. Additional weight on the top of the building to detract UV rays or keep the system in formation is not needed.
