The Main Causes Behind Commercial Roof Bubbling and Cracking

Flat roof bubbling can be a significant issue for building owners, often caused by two common problems: blistering and alligatoring. Blistering leads to the formation of small bubbles under the roof’s surface, which can ultimately result in cracks that weaken the entire structure.

The causes of flat roof bubbling and cracking are diverse, but they all point to issues with the installation or maintenance of the roof. Therefore, addressing these issues early on is essential to prevent further damage. This article will explore these causes in detail.

What Are the Causes of Commercial Roof Bubbling and Cracking?

Here are the main causes of commercial roof bubbling and cracking:

1. Poor Installation

If the commercial roof is not installed correctly, it can lead to bubbling and cracking. For example, if the roof is not installed with the correct amount of adhesive, it can cause the roof membrane to buckle and form bubbles. 

2. Lack of Maintenance

Lack of proper maintenance can also cause commercial roofs to bubble and crack. For example, if debris accumulates on the top, it can cause water to pool, eventually leading to cracking and bubbling.

3. Weather Conditions

Extreme weather conditions such as heavy rainfall, high winds, and extreme temperatures can cause commercial roofs to bubble and crack. For instance, if the temperature fluctuates rapidly, it can cause the roof to expand and contract, leading to cracking.

It’s essential to choose a commercial roof that is designed to withstand the local climate conditions. Additionally, routine maintenance and inspections can help identify and address any damage caused by extreme weather conditions before it becomes a more significant problem.

4. Age

Over time, commercial roofs may begin to deteriorate and become less flexible. It can cause them to crack and bubble.

It’s essential to have your commercial roof inspected regularly and to replace it when it reaches the end of its lifespan. A reputable commercial roofing contractor can help you determine when it’s time to replace your roof and can recommend a suitable replacement option.
