Flat roofs are common in commercial buildings but can also be found on garages, sheds and other structures at home. These roofing types provide many benefits for homeowners, including easier access and more cost-effective construction than a pitched roof. When properly maintained, they are durable and long-lasting. But it’s important to choose the right material for your flat roof, as a variety of factors can affect its longevity and performance, such as weather conditions, building use, and installation methods.
Several options are available for flat roofs, from traditional built-up roofing and Modified Bitumen to more modern single-ply membranes like EPDM or PVC. These products are lightweight, offer reflective options for energy savings and easy installation, and are highly durable and resistant to extreme weather conditions.
One key element that makes a flat roof more resistant to leaks is proper drainage. Water pooling on a flat roof can damage the materials underneath, so engineers build in gentle slopes that guide water into drains or scuppers (outlets in walls) or over the edge of the roof into gutters. These slopes can be created by taping insulation or incorporating structural slopes into the framing of the building.
Another issue that can arise is puddling, where dirt, debris or other obstructions block a drainage system. This can cause water to back up, creating a pressure head that forces the water into the smallest hole or crack in the barrier cover. If not addressed promptly, this can eat through the flat roof and enter the building. A skilled roofer will ensure that the proper slope and drainage are in place before installing any materials on a flat roof.
The flat shape of a roof is also a prime location for unique applications, such as solar panels, a garden, a rooftop patio or even a green roof. These applications can reduce your energy bills, but they require proper design and reinforcement to ensure safety and longevity. They also require barriers to protect people from falling debris and snow accumulation.
Whether your flat roof is an existing structure or new construction, waterproofing is a critical part of any installation. It’s the unsung hero that keeps water from seeping into the building and causing damage or leaks. Flat roof waterproofing is made up of a combination of layers and sealants, and it’s critical to install them correctly to ensure long-term protection.
When choosing a flat roofing contractor, it’s essential to find a company with experience in all types of flat roof construction and maintenance.
