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.

Bitumen is a good waterproofing material due to its nature. It is easy to apply and economical. Bitumen-based liquid membrane and bitumen-based roll membrane materials are the most well-known, economical, and high-performance materials used for roof insulation.
In order to complete the waterproofing of the roof perfectly, it is necessary to use bitumen-based waterproofing membranes, as well as chamfer tapes for corner leaks, drainage systems to prevent water accumulation, coating materials to protect the top layer, and various cement-based waterproofing materials to make the concrete waterproof.

Which is better silicone or elastomeric roof coating?
Longevity – Many factors can affect the longevity of an elastomeric coating, but mil for mil, silicones last longer than acrylics. This is mostly due to the inherently superior UV and moisture resistance of silicone materials.
What kind of sealant do roofers use?
Polyurethane – Polyurethane sealants have some resistance to sunlight, though not as much as acrylic sealants. The greatest strength of polyurethane sealants is their high degree of resistance to water. This makes them a popular option for anyone needing a sealant for a roof in an area subject to significant amounts of rain and snow.
