Roofing Repair Q&A in Hancock County, WV
Rubber roofing has blisters and is swelling. Is it serious enough to have a roofing contractor take a look at it?
Absolutely! Swelling or blistering is a sign of moisture infiltrating the roofing membrane.
Any type of soft flat roof, such as rubber roofing or asphalt, is susceptible to blistering or swelling. It’s not a normal occurrence, so it’s an issue you should address right away. Swelling and blistering will worsen if not fixed, and the longer you wait, the more expensive the repair will be.
There are multiple reasons a flat roof would start to blister or swell. Here are a few of the most common causes:
- Moisture collects beneath the rubber membrane either from a crack in the membrane, at a seam or near chimneys/vents/flashing.
- Plywood sheathing may have expanded because of water damage and/or changing weather conditions. Plywood sheets are supposed to be spaced about 1/8 inch apart to allow for expansion/contraction, but sometimes it is improperly installed.
- Certain types of rubber roofing, namely EPDM, can 'bubble up' when exposed to certain chemicals, such as refrigerants, grease and oils.
No matter what the cause, it’s important to address the issue as soon as possible, so that a small roof repair doesn't turn into a major expense, like a full roof replacement.
