If you own or manage a commercial building, you likely have a flat roof system. While these roofing systems are very versatile, they require special care and maintenance. How do you know if your commercial building's flat roof is on the verge of leaking? It's difficult to tell by looking, but a commercial roofer can reveal emerging problems with regular inspections. What are some of these problems?

1. Membrane Tears, Splits, and Punctures 

If you notice tears, splits, or punctures in an otherwise brand-new structure, they often indicate problems with how a flat roof was installed to begin with, and could point to faulty materials or poor craftsmanship. The roofer will make plans to rectify these problems.

2. Ponding Water 

The relatively flat pitch of a flat roof makes it prone to ponding problems. This is more so if the roof's surface is not leveled properly for water to flow downwards. Ponding water poses a risk to a flat roof. 

It can lead to leaks, mold growth, and even structural damage over time. If the inspection reveals your flat roof has been damaged by ponding water, ask the roofer to make plans for proper leveling. 

3. Organic Growth 

Flat roofs are vulnerable to organic growth because soil and debris can collect on the roof. Humidity quickens the growth process. Organic growth includes fungi, moss, and algae.

If possible, organic growth is something that you want to avoid, as it will make repairs more difficult later on down the road. The commercial roofer's inspection can reveal the extent of the infestation. The roofer can make plans for removal and disinfection. 

4. Blistering or Alligatoring 

By definition, a blister is a small bubble caused by trapped air on a roof surface, while alligatoring is caused by trapped water that gets in between roofing materials. Both conditions cause buckling and peeling of the roof membrane. Luckily both conditions are easily identified and corrected during a commercial roof inspection.

5. Roof shrinkage 

Flat roofs are vulnerable to shrinkage over time, especially in areas with high humidity. These materials become more brittle and susceptible to cracks or breaks as they age. These broken pieces can then detach and be blown away by strong winds. An inspection will reveal this problem and enable a fast remedy.
