Roof blistering can occur in almost any type of roofing system, but it is most common in asphalt shingle roofing and flat roof membranes. The blisters can be caused by a number of factors such as moisture problems, poor ventilation and improper roof installation. Blistering occurs when the roof adhesives fail, resulting in bubbles that can fill up with water or air. Fluctuating temperatures further affect these bubbles by making them expand when it is hot and contract when it is cold.
Although roof blisters aren’t usually a serious problem, they can be unsightly and, if left unaddressed, can eventually cause further damage to your roof. That’s why it’s important to invest in regular inspections and maintenance for your roof. Here are a few tips from our experts at Thomas Roofing Company, Inc. on how to prevent this common problem.
How Serious Are Roof Blisters?
One or two blisters or bubbles in isolated areas are generally not serious and you won’t need to contact your local roofing company for a full replacement. However, if the blisters are a foot in diameter or larger, they could expose the vulnerable underlayment and roof deck underneath the shingles. At this point, the roof will need to be repaired or potentially replaced.
Can You Prevent Blisters?
Unfortunately, roofing blisters are a symptom of an aging roof. Towards the end of a roof’s lifespan, it’s likely that fluctuations in temperature may cause blisters to develop on the surface. If blisters are already present, avoid foot traffic on your roof as much as possible, even if you’re tempted to take a closer look. Stepping on the roof can pop the bubbles and cause worse problems.
Hire a certified roofing contractor to perform regular inspections and maintenance on your roof. A professional inspection is the only way to identify potential blistering problems early on and prevent any further damage to the roof.
