Why Commercial Roofs Fail...


As a property manager or building owner, it’s often easy to take the roof for granted, especially if there are no obvious leaks or failures. This is one of the top reasons that we offer our Commercial Roof Reports. These reports not only check the health and condition of every inch of your roof, but they also give you estimates on any future needs or repairs so you can avoid surprises and plan accordingly. While others charge upwards of $500 for a Commercial Roof Report, we give it to you for free.


There are several things that we look for when doing inspections. Below are some common issues that we see. If you have these types of roofs and don’t have a report, call or email us today so we can get you some peace of mind.

If you have a Modified Bitumen roof, then the greatest opportunity for failure is due to seam failures and penetrations. There are lots of vertical and horizontal seams - which means more opportunities for issues. In a perfect environment, these failures are unlikely. Unfortunately, the vast majority of the work for this type of roof is done in the field, where lots of variables can affect the quality of the install. Because of this, getting back on the roof to track potential problem areas is extremely important. One seam failure can wreck whole sections, or worse.

TPO, which stands for thermoplastic polyolefin, and PVC (Polyvinyl Chloride) come in huge sheets. If you have this type of roof and it was installed properly, you will have fewer seams and possible failure points. In addition, most of the work is done in the manufacturer’s facility which minimizes the variables that can affect install quality. If and when TPO fails, it typically happens in the field, which means it’s easier to find and repair.

Built-Up Roofing Systems is made up of several layers of felts or fabrics that then are saturated. When installed properly, these are typically low maintenance. Because of the materials in play though, they can be susceptible to wind and water damage. It often requires a trained eye to spot potential problems BEFORE damage occurs below.

Liquid or Foam Coatings are by far the most problematic when it comes to protecting the building below. The reason for this is that the application process is very labor intensive and very susceptible to mistakes that often lead to expensive repairs. If you have a roof with this material and don’t have a roof inspection report, we strongly encourage you to call or email us today.
