5 Important Things You Need to Know about Silicone Coatings on Metal Roofs

Metal roofs can be found on all types of buildings including industrial or commercial buildings through Los Angeles and Orange County. One standout reason is because metal roofs have remarkable longevity; they can endure for up to 70 years! However they do not last forever and in many cases they can be restored rather than replaced.

Enter the world of metal roof restoration, where acrylic and silicone cool roof coatings take the spotlight. While both coatings are praised for their compatibility with various roofing substrates, the effectiveness of silicone coatings on metal roofs has received mixed reviews.

So to help sort this out here are 5 things you need to know about silicone coatings on metal roofs.


1. Waterproofing and Sealing on metal roofs:


Silicone coatings create a seamless, waterproof membrane when applied to a metal roof. This helps to prevent leaks and water damage, which is essential for flat roofs that are more prone to ponding water.


2. Reflective and UV Resistant:


Silicone coatings are typically reflective and UV-resistant, which can help reduce the roof’s temperature and energy costs. The reflective properties can also extend the life of the roof by reducing the effects of thermal expansion and contraction.


3. Durability:


Silicone coatings are known for their durability and long lifespan. They are resistant to extreme temperature fluctuations, UV rays, and other environmental stressors. This can significantly extend the life of a metal flat roof.


4. Easy Maintenance:


Silicone-coated metal roofs are relatively low maintenance. They require periodic inspections and cleaning, but the coating itself is resistant to dirt and debris buildup. Any necessary repairs or recoating can be done fairly easily.


5. Professional Installation:


Proper installation is crucial for the effectiveness of a silicone coating. It’s advisable to hire a professional roofing contractor with experience in silicone roof coatings. They will ensure that the surface is adequately prepared and the coating is applied correctly for the best results.




The key to determining the effectiveness of a coating on a metal roof ultimately falls to the preparation. So doing your due diligence when hiring a commercial roofer can go a long way into protecting your investment.
