Commercial roofs, for the most part, are built with durability and dependability in mind. However, that isn’t to say that they are completely infallible and prone to issues. With flat commercial roofing systems, in particular, blistering is a common problem. In today’s article, the experts over at Pritchett Bros explain what causes flat roofs to blister and share a few tips on how to prevent it from happening in the first place.
What Is a Roof Blister?
Roof blistering is a common issue faced by commercial property owners with roofs that have field-applied exterior coatings, such as paints as well as those with built-up roofing (BUR) systems. In a BUR roof, blisters are raised surfaces over voids which contain air or moisture and sometimes both. When your roof heats up, the pressure inside these blisters rises, and the adhesion of asphalt weakens.
Blisters, in general, are most noticeable on hot days. They can range from small, spongy areas to large, more noticeable areas. As mentioned before, blisters usually develop from voids built into the roof caused by skips in bitumen mopping and entrapped debris as well as uneven gasses and bitumen bubbling.
How to Prevent Roof Blisters
As with most roofing issues, prevention is the best cure. When you get a new commercial roof, make sure that you are working with a reputable and experienced company. You should also keep foot traffic at a minimum and have your roof cleaned and maintained regularly to prevent moss and algae growth which could expedite and add to the problem.
