Flat roofing has a lot of benefits, but it does require different kinds of maintenance than a standard sloped roof. Flat roofs require more maintenance and when there is a problem, it can grow exponentially very quickly. However, if you know the challenges of a flat roof, you can work against them.
Issues With Flat Roofs
You have a higher chance of developing water damage when you do not have a sloped roof. The flat roof does not promote water to run off and instead, pooling may occur. When water pools, it has the potential to damage the underlying roof. Pooling water can lead to mold and structural problems.
In addition, some traditional materials do not make good materials for flat roofing. For instance, you may not be able to get a seal between rooflines or chimneys with a flat roof. Sealing breaks are more difficult because metal flashing is not adequate.
Solutions for Flat Roof Issues
Roofers tend to use rubber or plastic to prevent water from penetrating the roof. Even if you have a flat roof with asphalt shingles, odds are there are plastic and rubber layers under the roof. One of the most common ways to install flat roofing is to interchange levels of tar and water-resistant fabrics. Then, the contractors cover the material with gravel. The gravel allows the water to drain but also prevents any pooling. Next, the tar level keeps the water from penetrating the structure.
Contractors may also choose to lay a bitumen layer on top. The layer reflects heat and keeps the roof more energy-efficient. Another method is to install a rubber membrane to prevent water penetration.
Flat roofing does not have to be more complicated than a traditional roof, as long as you understand the challenges and the solutions. Trusting your installation to a qualified contractor can help reduce future problems.
