Flat roofs are notoriously leak-prone. That’s why, as a general rule, they should be inspected at least twice a year. Through routine inspections, commercial roofers can detect the warning signs of damage and fix roofing issues before roofing damage affects other parts of your building. The sooner a roof leak is found and fixed, the better. 

In addition to keeping track of their roof’s maintenance routine, it’s also important for building owners to at least have a basic understanding of the causes of commercial roofing damage. 

The usual suspects behind commercial roof damage are: 

1. Clogged Drains

The term flat roof is actually a misnomer: the surface of the roof is slightly elevated to make sure water flows to the drains. However, if leaves and other debris are clogging the drains, water will start to pond on the roof’s surface. 

2. Standing Water

As a general rule, you shouldn’t leave standing water on your commercial roof for more than 48 hours. Standing water not only adds to the weight load your roof has to support but also magnifies damaging ultraviolet rays, which can prematurely age your roof. 

Here’s a pro-tip: To strengthen your roof’s defenses against UV rays, we recommend adding roof coatings. Keep in mind that not all roof coatings can provide the same level of protection. That’s why it’s highly recommended that you consult a professional contractor before choosing a roof coating. 

3. Wear and Tear

Routine maintenance can extend your roof’s lifespan, but it can only do so much. At a certain point, you’ll need to install a commercial roof replacement. 

How can you tell if it’s time to replace your roof? By keeping an eye out for warning signs like water stains in the building and bubbling roof membranes. And if you’re still not sure if a roof replacement is needed, you can have an experienced inspect your roof.
