Silicone roof coatings are a type of elastomeric roof coating that are made from silicone polymer. They are known for their exceptional durability and resistance to extreme weather conditions, making them a popular choice for protecting commercial and industrial roofs.

One of the main benefits of silicone roof coatings is their ability to withstand high temperatures. Unlike other roof coatings that can become brittle and crack in extreme heat, silicone coatings remain flexible and can expand and contract with the roof without cracking. This makes them an ideal solution for buildings located in hot climates, such as desert regions.


Silicone roof coatings are also highly resistant to water and moisture. They form a seamless barrier against leaks and water penetration, which can help to prevent costly repairs and extend the life of the roof. In addition, they are also resistant to mold and mildew growth, which can be a common problem in humid environments.

Another benefit of silicone roof coatings is their energy efficiency. They have high reflectivity which can help to reduce the amount of heat absorbed by the roof, which can lower cooling costs and improve the overall energy efficiency of the building.


Silicone roof coatings are also easy to apply and maintain. They can be applied using a roller or brush, and typically only require one or two coats for optimal protection. They also do not require any additional primer or sealer to be applied before coating and once applied they can last up to 25 years.

Silicone roof coatings are also environmentally friendly. They are made from non-toxic materials and do not contain any harmful chemicals or volatile organic compounds (VOCs). This makes them a safe choice for both the environment and the people who use the building.

If you're in need of a robust and efficient roof coating solution, silicone coatings are a great option to consider.



  • I recently used Grandmark Service Company for a roofing repair project and new ductwork for my central air and heat unit. Two new solar light tubes and two exterior roofing vents for my whole house fan. First Grandmark was quick in sending out a Technologist to assess my roofing repair. The repair was done in a very professional manner with special attention paid to a down spout. I can't thank that tech enough for the excellent work and attention to detail. I then decided upon inspection of my existing ductwork to have it replaced. Again, the crew removed all the old ductwork out the top of the attic where the new exterior vents would be placed saving me a ton of clean up. Throughout this process they provided tarps on the floor and did a thorough clean up at the end of the day's work. All crew member's were professional and friendly and answered any questions. If I could I would give them ten stars. But for this review five stars will have to do. Again, thank you Grandmark service company. I won't hesitate to use you again should the need arrive.

    Recently moved to the central valley, got 3 quotes from other companies that were way over priced. They finished the job in less than two weeks. Highly recommend this crew..will be using them for solar install in the future
