Common commercial flat roof problems

Here are common flat roofing problems and how to deal with them.

Leaks & Moisture

Because of the flat surface, water can go straight down the roof when it rains or snows. Over time, your roof can slightly shift, which means it might not be as level as it was after installation. This can cause water to settle in the divots and dips of the roof.

Immediately drain these pools, and make sure the water didn’t get through the lower layers of the roof. Moisture that seeps into the roofing material can result in mold or fungus, and shorten the lifespan of the system. Makes sure your roof is regularly inspected and maintained to avoid this issue.


Alligatoring occurs when the asphalt used to build your flat roof has reached the end of its life. The asphalt loses elasticity, causing the surface to crack, bubble and look like an alligator’s skin. A roof replacement is the only way to remedy this problem.


Usually, flat roofs are made up of a membrane submerged in asphalt and then laid across the top of a structure. Excessive movement can cause buckles in the asphalt membrane, which indicates you need to replace your roof. It’s not safe to occupy a building with a roof that’s buckling.
