With nearly two decades of experience, we would venture to say that we have seen about every time of commercial roof damage you could imagine. In today’s blog post, we would like to share with you some of the most common types of leaks that affect a commercial roof.

As is the case with all roof leaks and damage, commercial roofing leaks require prompt repairs. Leaks will not just sort themselves out with time. In fact, they will do the opposite — over time they will get worse and worse, necessitating more damage and more costly repairs.

One of the biggest threats to a flat commercial roof is pooling water. If your flat roof isn’t able to drain properly, it will start to look like a swimming pool. Roughly one square foot of pooling water weighs five pounds per inch of water. This is quite the burden on your roof, and before no time at all, this water will begin seeping into the interior of your commercial property. The good news is that a lot of times the cause of the ponding water may just be a problem with the drainage system. It could even be as simple as a clogged drain.


Almost all roofs have a number of pipes, drains, and other items that puncture the roof membrane. This is not uncommon and it’s a necessary part of nearly all commercial properties. However, these protrusions or penetrations are especially prone to leaks and should be carefully inspected regularly. When performing an inspection, pay particularly close attention to the flashing, field wraps, rain collars, pipe boots, pitch pans, and any other areas that may be susceptible to leaks. These special areas include drains, pipes, gas lines, HVAC units, and any other objects that are routed through your roofing membrane.


Nothing lasts forever. This includes your commercial roof. No matter how well-built your roof is, there will come a time when it can no longer be patched up and needs a replacement. If you refuse to accept this, your roof will be susceptible to leaks. Most flat roofing systems last anywhere between 15 – 20 years. This being said, roofs can last longer, and with proper roof maintenance and prompt repairs, you can drastically improve the life of your roof.


As your roofing membrane ages, the materials begin to break down and deteriorate. This may take the form of cracking, splitting, blistering, shrinking, and puncturing. Naturally, when this type of deterioration occurs, the vulnerable part of your roof under the membrane becomes exposed to water. This is, of course, problematic because the primary function of your roofing membrane is to prevent water from reaching the interior of your commercial space. If your roofing membrane is visibly damaged, your commercial roofing system is overdue for repairs. Ignoring this problem will only lead to more damage. For roofing systems that are not that old, prompt repairs could be the difference between a few repairs and an entire roof replacement.
