One of the most common problems that local roofing contractors like us get called in for are blisters on commercial roofs. Even if you haven’t had blister problems on your own commercial roof, being familiar with them and how to address them is important. Carney Roofing Company can give you a closer look at what you can do if you find roof blisters.
What Causes Roof Blisters?
Blisters develop from pockets of air or moisture trapped between the layers of roofing material. Most roofing materials stretch when heated by sunlight, which makes the pockets expand, resulting in blisters. The blisters shrink back when the temperature becomes lower, but the expansion sometimes affect the adhesive underneath and makes the blisters permanent. In some cases, the material cracks from the pressure, allowing air and water infiltration that increases the chances of developing blisters over time.
Fortunately, blisters are entirely repairable. Some property owners puncture the blisters to purge the air and water underneath, but this is merely one step in the repair process. Leaving them alone would be no better than waiting for the blisters to break open. It is best that you contact your roof maintenance company to address the blisters.
The repair process depends on the roofing material. For roofing material attached using adhesives, the entire blistered area will have to be cut out, as the adhesive may already be contaminated. The area will then be cleaned, and a fresh layer of adhesive followed by a patch of the same material as the original roof. Ballasted or heat-welded materials will only require a patch or sealant to fix the issue.
Investing in quality installation is still the best way to prevent blistering. A lot of instances of blistering is caused by improper installation. For example, untrained installers skip on using the proper tools and procedures to smooth out bubbles while the adhesive is wet. Hiring the right contractor who specializes in commercial roofing can save you from a lot of future repair work.
