Common Problems With Flat Roofing

If you own a commercial building with a flat roof that uses asphalt or gravel, you are probably familiar with the problems that come with it. At The Duerson Corporation, we use exclusively Duro-Last products to eliminate that majority of issues that come with maintaining a flat roof. If you are considering buying a commercial space with a flat roof that is not installed with a Duro-Last roof by The Duerson Corporation, here are some common issues you could be facing.


This is a term that is associated with roofs that use an asphalt membrane. As the weather breaks down the asphalt over time, it will lose its elasticity and start to dry out. This creates an effect that causes the asphalt to crack and bubble, resembling the dry skin of an alligator. If this were to happen, roof repair may not be an option. You may have to invest in a new roof made of sustainable materials.

Flat Roof Flashing

Buildings all around the Midwest experience the highest of highs and the lowest of lows for temperature changes throughout the year. This constant stress can cause the flashing on the roof to loosen its hold around the edges. In turn, this can lead to water and moisture getting under the surface, ultimately leading to more problems.

Pooling Water

Going back to the strain of weather on Midwest commercial roofs, water may begin to pool on your flat roof over time. As the heat and cold causes the roof to contract, the roof may start to slowly take a different shape over time. A flat roof building actually has a slight curvature to it so that water can escape to drain holes. However, the roof warping over time can cause water to puddle in places where it can no longer escape to the drain holes.

Roof Buckling

Since an asphalt roof is a single piece membrane, it is not that flexible of a material. As the roof, walls, and foundations of the building swell and contract over time, the membrane can sometimes buckle under its own weight. In the event of this happening, schedule an immediate roof replacement as soon as possible. It is not worth trying to repair a single-ply asphalt membrane that has buckled.
