What is Roof Seal

A roof is one of the most important components of a house to protect it from the elements and environment. Being exposed to the weather all day, you need a strong, sealed roof. This is why a roof seal is extremely important. Understanding the types, application and significance of roof seal can help you prolong the life of your precious home.

Roof seal, also known as roof sealant, is a protective coating that is applied to roofs to strengthen their durability and weather resistance. It acts as a barrier stopping roof penetrations such as water, UV rays and other harmful elements. Roof sealants can be applied to a range of roof material types such as colorbond metal, asphalt or a tiled roof roof.
