Flat Roof Blistering: Causes and Prevention

Roof blisters are extremely common problems for roofing systems. These are most commonly noticeable during hot and sunny days, and they range from small spots to large areas. However, before you get up your roof to check on your flat roof blisters, think about calling a professional roofer first. Roofers will be able to identify the main cause of the problem and address them. 

Why Is Your Flat Roof Blistering?

Blisters can form in three ways:

• Moisture
• Poor installation
• Poor ventilation

When air or water gets trapped in your roofing, it will form a blister. These blisters will look like bubbles on your roof. Eventually, small blisters can grow bigger and allow more moisture inside. This can be the cause of big water and structural damage to your home. This is why it’s important to have your home regularly inspected and maintained by professional roofers. They will check the problem and address them before they become bigger.

How to Prevent Blisters

There are three ways you can prevent these blisters from appearing:

• Keep the roof dry. With no moisture or trapped water in your roof, there is no way your roof will blister. Make sure to dry out your roof especially after a strong storm. Also, you may check for leaks before and after extreme weather conditions. Another important aspect of a flat roof is that it should have a proper drainage system. This will make sure that water is drained regularly and not stuck on your roof to create leaks and blisters.

• Ensure proper installation. When having your flat roof installed, make sure to hire the correct professionals for the job. Professional roofers will make sure that your materials have firm contact between them so that the adhesion will work properly. Your roofers will also install an insulation board, clean their work area, and create a proper ventilation for the new roof system.

• Schedule regular Inspections. Make sure your flat roof undergoes routine maintenance carried out by qualified roofing professionals. They will make sure to detect problems that may not be visible to the untrained eye.
