What is roof alligatoring? This is one of the most common questions we have received from property managers.

Commercial roofs are exposed to the sun the whole year, which can be affected by UV rays.

Plus, during the yearly rainy season, precipitation can cause ponding water and hail damage. 

However, these are only some of the factors involved in roof alligatoring. 

Your roof maintenance program and your property location also play a fundamental role.

Roof Alligatoring: What is it?

It is roof damage that commonly happens in flat, aging roofs. 

In most cases, exposure to UV rays is the main reason because it can dry out the top coat membrane, causing it to crack. 

Other factors such as ponding water, dirt, hail damage, snow, and extreme temperature changes can cause cracks too. 

It usually starts in a tiny part of the roof and gradually expands as cracks widen and extend.

The older your roof gets, the greater your chances of having it will be.

Nevertheless, if you have identified cracks, call a roofing contractor immediately.

The worst you can do is leave it to its own luck, as it will only get worse.

How to Prevent Roof Alligatoring?

Start by including regular roof inspections.

Inspections will help you identify roof damages before it is too late, making it easier to repair cracks as they occur. 

In addition to inspections, consider adding an IPP Silicone-based restoration system. This will keep you safe from roof alligatoring for up to 25 years or more.

Lastly, please keep in mind that if you do not identify roof alligatoring on time, you might need to replace the entire roof.
