Changes in the weather may result in roof blisters. Causes of roofing blisters may vary, and for Arizona residents with new flat roofing systems and annual storms, knowing how to fix blisters, ways for preventing roof blistering on commercial flat roofs, and why roof blisters happen is an important part of regular roof maintenance that keeps their homes protected in this harsh climate. They may not require immediate attention, but failing to address the problem of roof blisters could damage the membrane and expose the underlying substrate to moisture. Don’t ever leave obvious roof system damage unaddressed.
Why Do Roofs Blister?
If you’ve ever wondered why roof blisters happen, we have complied a list of causes of roofing blisters, tips for preventing roof blistering, and how to fix blisters on flat roofing if you have started noticing some. Understanding what they are, what they will mean for your blistering roof, and the best ways to respond them can be an important part of roof maintenance for your home, especially if you are an Arizona resident with a flat roof.
About Causes of Roofing Blisters
Blisters on flat roofing occur on any type of flat roof system materials (such as bitumen), whether it is a membrane roof or a built-up one. You’ll need guidance on how to fix blisters on flat roofing and methods for preventing roof blistering to deal with a blister area early.
Adhesion between Layers of Materials
Blisters are raised surfaces that occur in areas where there is a loss of adhesion between layers like bitumen. Generally, causes of roofing blisters have to do with trapped air or water within a flat roof membrane or built-up roof. Air or water fill up the gaps between the membrane system layers, resulting in bubble-like protrusions.
Trapped air or water bubbles in the membrane will expand in warm or hot weather while dry or cooler temperatures at night will cause it to contract. Apart from moisture in the membrane, they also happen because of poor installation and ventilation. Unless the bubbles burst, blisters can grow larger inside the membrane.
Ways for Preventing Roof Blistering
The surest way is having a proper, quality flat roof installation in the first place, and a skilled roofer handling your maintenance afterwards. When you are looking to install a new roofing system for your commercial property, you need to choose the best professional contractor who can do the project according to the manufacturer’s specifications. This small step helps for preventing roof blistering, and catching them early.
More Blister Prevention
Otherwise, it is important to keep foot traffic on the surface limited, especially in warmer weather. Walking over a blister area can break it open, exposing the surface to the elements that could cause further damage. Of course, be sure to keep your roof cleaned and maintained to prevent moss or algae growth. Since moisture and air are the major causes of roofing blisters, keeping bubbles and pools of water out and not allowing growth of life forms in the membrane area which could produce air will help.

If Blistering Roof Worsens
A blister is one example, but many types of roofing issues occur that start small and insignificant. Yet they grow and develop further problems (sometimes gradually, sometimes more suddenly) until a roof is experiencing serious problems. If a homeowner has not taken time for the condition of their roof, they can find themselves paying a lot of money for roof and home repairs, having to deal with roof problems at an inconvenient time, and many other possibilities. Make sure to get your new roof clean, dry, and inspected for repairs regularly after it is installed, maintaining it as needed.
