An increasing number of homes and commercial buildings are being built with flat roofs. These roofs are easy to install, take up much less space than traditionally sloped roofs, can lower energy costs, and offer a sleek and modern appearance for both homes and businesses.

Though flat roofs can be a good investment due to their array of benefits, it is still essential that home and business owners keep an eye out for common flat roofing problems.

If you are experiencing flat roof problems contact Polaris Roofing Systems of Flagstaff, AZ for residential and commercial roofing services.

Flat Roof Problems

Here’s a brief list of some of the problems you should be aware of if you have or are considering flat roofing for your business or home in Flagstaff, AZ:

Debris Pile Up

Because the roof is flat, it is much easier for it to collect debris compared than a roof with a standard slope. Branches, twigs, and leaves can pile up over time, and if left untreated, can cause damage to the structure of the roof.

It’s crucial that you check for debris regularly and have it removed safely when possible.

Pond on The Roof

Flat roofs also collect water, which can lead to pooling. While flat roofs are generally sloped very slightly to allow for water drainage, rain can sometimes still accumulate.

If puddles of water freeze on your roof or remain stagnant for long periods, it can ultimately lead to cracks, which can then allow moisture into your home. Moisture causes mold and other damage that could require significant repairs if not caught in time.

Ensuring that your roof is draining correctly is an absolute must, especially with a flat roof.


Another common problem with flat roofs is that the extended exposure to the sun can cause areas to bubble. The bubbling process is known as “alligatoring” because it resembles the skin of an alligator.

To ensure your roof is well-maintained, it’s crucial to mend the bubbles as soon as possible; if left untreated, they can cause further damage to your roof and home.

Wind Damage

While not as common of an issue as some of the problems listed above, flat roofs can be susceptible to increased damage from strong winds because it is made of one piece rather than hundreds of shingles. The good news is that this type of damage will likely only occur as a result of very powerful winds.

Not as Durable as Some Other Roofs

While flat roofs can easily last 10-15 years with regular maintenance and proper care, they do generally have a shorter lifespan than wood or metal roofs. That said, many roofs don’t last a long time due to improper care.

If you have flat roofing on your home or business, it would be best if you stay on the lookout for these common problems so you can stop any lasting damage from occurring.
