Common Issues With Flat Roofs
While a flat roof might appear level, most are set at a 10° angle or less to allow rainwater to run off on the lower side. Flat roofs are ideal for various reasons, but there are a few disadvantages to keep an eye out for:
Pooling Water
Even though most flat roofs are made with a slight slope for drainage, water can begin to pool after heavy rain or snow. This can lead to leaks or damage to the exterior of the roof if not addressed promptly.
Debris BuildUp
Flat roofs lack the natural slope found in other roof types, making it easier for leaves, branches and other debris to collect on the roof and potentially clog the drainage.
Alligatoring
This term is used to describe cracking and bubbling on flat roofs that resembles alligator skin. It is caused by prolonged sun exposure and can lead to potential roof failure if left untreated.
Longevity
Flat roofs face significant damage from elements such as sun, weather, and pollutants, leading to damage and common issues like sun damage, lightning, frost, and wind damage.
