Common Problems with Flat Roofs

While flat roofs are commonly seen on commercial buildings, they are are also used for homes. Some homes even have a combination of pitched roofs and flat roofs. Flat roofs, while not completely flat, are designed differently and they have their own set of unique problems you’ll want to be aware of compared to pitched roofs.

1. Standing Water
   While called, “flat,” flat roofs are still slightly angled to allow proper water drainage, but not as easily as pitched roofs so snow, ice, and water can accumulate on them. It’s important not to let water sit on your roof for too long because moisture can seep into your roof and cause fungus and mold growth. It could also lead to roof leaks and sagging.
2. Blistering
   Flat roofs begin to blister when they are reaching the end of their lifespan. In the roofing industry, this is commonly called, “alligatoring,” because it looks similar to an alligator’s skin. If your flat roof is blistering, this is a sure sign it’s time for a roof replacement.
3. Cracking
   Flat roofs undertake more pressure than slanted or pitched roofs so they may crack over time. If your flat roof is showing signs of cracking, it’s important that you have those areas repaired before it leads to further damage.
4. Buckling
   If your flat roof was sealed with an asphalt membrane, it’s important to understand that it may begin to buckle over time as your home settles and shifts. If you’re noticing buckling asphalt on your flat roof, it may be time for a roof replacement.
