Is it worth sealing your roof?

What Does Sealing a Roof Mean? – Roof sealants are added to your roof to extend its life expectancy. Sealing a roof provides an extra layer of protective coating that can help prolong damage from extreme climates and other hazards, including sun, rain and ice.

The idea is to let the roof coating take a beating, instead of a roof’s tiles or shingles. Roof coatings are especially useful for roof types that collect water and debris, such as flat roofs. They can also be used on other angled roof types as they age to protect from long term damage. Roof sealants can make your roof a little more fire-resistant, and prevent the growth of mold and algae.

Roof sealants and coatings need to be applied by experienced, professional roof contractors. For instance, a novice roofer may leave pinhole-sized openings in the coating which, believe it or not, are often enough to cause leaks and other issues. So, in a word, hiring a quality roof installer is vital.
