Bay Area Roofing Pros Discuss Flat Roofs

Flat roofing systems have a lot going for them, including affordability and versatility, which is why Bay Area roofing contractors like us often recommend them for commercial and apartment buildings. Still, when it comes to flat roofing, you should be on the lookout for these 10 problems. Spotting them early can save you headaches down the road.

Damage from the Elements

Many Bay Area reroofing projects become necessary simply because the roof has been exposed to the elements for a long time. Inevitably, sun, wind, rain, and other natural forces will wear a roof out, though maintenance can drastically slow the process.


Blistering is one of the most telltale signs of sun damage on a flat roof. As the name suggests, blistering occurs when a flat roof’s material appears to bubble up.

Lack of a Maintenance Plan

If you’ve recently purchased a flat-roofed property, or are about to, it’s worth investigating whether its roof has been enrolled in a maintenance plan. If it hasn’t, it’s more likely to suffer from the other problems on this list.

Pooling Water

If water is pooling on the roof, our Bay Area reroofing company urges you to take prompt action. Pooling water may eventually cause leaks or larger roof failures.


Plants and algae look perfectly at home in nature, but they’re a bad sign on a flat roof. They point to improper drainage or dirt buildup on the roof.

Debris Buildup

Debris is another sign of a dirty or poorly draining roof. Additionally, once debris starts to build up because of drainage problems, it can cause additional clogs, exacerbating the issue.


If your flat roof springs a leak, it’s important not to shrug this issue off: Small leaks can become big ones in a hurry.

Shrinking Materials

Certain flat-roofing materials are prone to shrinkage, which manifests as small holes in the surface of the roof as the material pulls apart.

Puncture Marks

Punctures in the roof can result from forces like hail or falling tree branches, but repairs may alleviate the problem.

Flashing Issues

Flat roofs contract and expand as the temperature changes, and the flashing around the edges of these roofs can sometimes suffer damage as a result.
