Over time, the commercial roofing systems tend to get damaged and worn out. That’s why it is important for building owners and facility managers to anticipate roof problems before they can even occur. With enough planning, these problems can be easily handled at first sight.

In this guide, we will be looking at the most common problems a commercial roof may experience throughout its lifetime along with how they should be handled.


A leaking roof is always a problem, no matter how you look at it. If you see signs of a roof leak, take action as soon as possible. Roof leaks, no matter how small they may appear, can definitely ruin not just your roof but other parts of the building as well.

What you can do is to arrange a preventive commercial roof maintenance program so the leaks can be fixed in no time and avoid other potential problems to occur.

A Quick Guide on Fixing a Leaking Roof


Shrinkage often occurs in single-ply roofing systems. You may notice flashings pulling away from the wall and cracks on uncured membrane.

Regular roof inspection is highly advisable. It is best for building owners to have their roofs inspected twice a year, ideally.

Billowing, Tenting and Blow-Offs

If your roof is not properly attached to the substrate, the seams can get exposed to the elements causing parts of the roof or the entire roof to blow off. These problems are be typically found in single-ply roofing systems.

To avoid these problems, your roof must be able to withstand winds. Hire highly experienced roofers to fix these issues.

Poor Installation

A poorly installed roof is considered a problem to cause many other problems. Unsatisfactory workmanship may result to minor and major costly roof repairs.

Don’t ever settle with an unreliable roofing contractor just because they may offer unbelievably low priced roofing services.
