Roof Shingle Blisters and How to Prevent Them

A roofing maintenance plan from trusted roof install service providers is important to keep your roof in working order. With weather changes, roof blisters may pop up on your commercial or residential flat roof. While roof blisters may not need immediate attention, if left unmonitored, they could lead to saturated insulation and a damaged membrane.

Roof systems with membranes are more prone to blistering because blisters are formed by gaps between the membrane plies or between the underlying substrate and the membrane.

A Look at Roof Blisters

According to siding and roofing pros, a roof blister is a raised area where there is a loss of adhesion under the layers of roofing. This area can fill up with air or water to form a blister – which looks like a bubble on your roof. It often occurs in asphalt-based roofing systems like built-up roofing (BUR) or asphalt shingles.

Some blisters are small, harmless and inevitable, but in other cases, these weakened areas allow more damage to your roof, eventually leaking, and even complete roof failure. A common cause is lack of moisture, poor installation and poor ventilation.

How to Prevent Roof Blisters

If popped, roof blisters could lead to further damage to your roof, which means a higher overall cost for repairs. The best way to avoid costly repairs is to regularly maintain your gutters to avoid excessive moisture that can cause roof blisters.  M&A Exterior Home Improvement can assist you with unclogging and cleaning out your gutter system to keep it functioning properly through every season.

Proper Installation

The common cause of blisters is improper roof installation, often from cutting corners and/or not following instructions and specifications provided by the material manufacturer. Make sure your materials have firm contact between them for the adhesion to work properly. Ensure you hire the right roofing contractor and talk to them about installing your roof to the manufacturer’s specifications.

Maintenance Plan

Having a maintenance roofing plan is a must! Keep your roof free of moss and algae and regularly remove debris from the valleys. Keep a gutter cleaning schedule and check other areas where debris may accumulate on the roof and trap moisture. A regular maintenance contract with a roofing professional is a great way to ensure your roof stays healthy for as long as possible. Supporting with a regular inspection.
