Different Types of Commercial Roof Coatings

Roof coatings are applied as a liquid layer over the finished roof and come in various colors. However, their key role is not simply to make a commercial building look its best. There are various types of commercial roof coatings and each of them has a precise functional role.

 

The Most Frequently Used Types of Commercial Roof Coatings

 

1. Reflective Coatings

This type of roof coating is light colored. Its main role is to reflect the sunlight from the roof and keep it cooler. How does it work? As you know, dark colors attract and absorb sunlight and heat. Light colors do the opposite (this is why, during the summer, it is recommended to wear white clothes).

 

A cool roof is a roof protected from temperature variations leading to cracks in the joints. Also, it can help reduce the costs with air conditioning in areas with a hot climate all year round.

 

2. Functional Coatings

These coatings are made of materials that are chemically compatible with the roof system (asphalt, concrete, metal, etc.). Their primary role is to protect the roof from the effect of UV rays and from weather conditions (hail, snow, high winds).

 

Functional coatings are easy to apply even by the regular maintenance crew. They need refreshing every once in a while, as they take the brunt of the elements.
