Three Common Flat Roof Problems


Although pitched roofs and flat roofs can have some of the same repair problems, flat roofs can have issues that are unique to them. Whether you have a business or a home with a flat roof, proper maintenance will eliminate most issues. Here are three repair issues unique to flat roofs.

Pooling Water

Pooling water isn’t uncommon on flat roofs since water doesn’t run off them as it does from peaked roofs. However, pooling water that is more than 2.5cm deep is a problem as it can cause further damage to the roof. Pooling water is usually the result of compressed insulation due to walking on the roof or placing heavy equipment on it. Since water adds more weight onto the roof, further compression can take place if the roof isn’t repaired.

Heat Blisters

If a flat roof isn’t vented correctly, then the material will blister when the roof gets overheated. The blisters in the material resembles small bubbles and can allow water to get underneath the material, causing further damage. However, roofers in Kellington can replace the damaged material and properly vent the roof so the problem does not reoccur.

Roof Shrinkage

Flat roofs covered with EDPM rubber have a tendency to shrink, which can cause tenting, the seams can come apart, or the roofing can lift. When it rains, the water can get under the rubber and cause the roof to leak. Fortunately, a roofing company can make repairs so the roofing is tight again, which will stop the leaks.

It is important for flat roofs to receive the proper maintenance to prevent damage and leaks. Minor issues that can be easily fixed can become major problems if they are ignored. To prevent costly repairs or replacements, contact a roofing company to inspect your roof at least once a year.
