Ask A Boston Roofing Contractor: Flat Roof Repairs

One of the biggest issues you're going to run into with a flat roof is blisters. Blisters can form because of heat and sun exposure, but here in the Boston area we also need to take into account the fact there's significant moisture in our environment throughout the winter and spring. If that moisture can sneak in around the flashing or seep in through a hole, it can become trapped, and as we all know, water expands when it's hot. When you have expanding water between your roof and your roof surface, blisters happen.

Flat roof repairs look deceptively simple. As a roofing contractor, I can promise you that appearances can be deceiving. You never truly know what's going on with a roof until you have the chance to inspect it and examine the condition of the roofing surface as well as the boards beneath and potentially the roof rafters. It's a good idea to have your roof repaired as soon as you know there's a problem, but sometimes people let stuff slide. This can result in the damage getting worse as moisture continues to deteriorate the structure.

In the Boston area, it's relatively rare to see a truly flat roof on a residential building. However, many roofs have flat areas, such as the connection point where the roof joins the chimney, or where wings of the house come together. Flat roofs that are covered with asphalt shingles and roll roofing are the most vulnerable to blistering. The blistering also dislodges the gravel that's part of the shingles, loosening it and removing some of your home's essential protection.

If you see blisters on your roof, call your Boston roofing contractor right away. A reputable roofing contractor is going to make an appointment to see you and the condition of your roof. That will help them provide an accurate estimate to aid you in your decision making process.
