The Advantages of Silicone Roof Coatings


NATIONAL REPORT—Silicone roof coating, also referred to as silicone restoration membrane, is an element that is applied directly on a roof using a special roof coating spray equipment made of silicone. The substance in the spray fills any cracks, seams, and blisters, thus extending the lifespan of a roof. But is silicone roof coating any good? How long does silicone roof coating last? Does roof coating stop any leaks? What are the advantages of silicone roof coating? This coating process is not for underlayment, but it is an excellent additional layer against the elements and climate.

Is Silicone Roof Coating good?

Yes, Silicone Roof coating is the best. It is good on buildings or apartments where ponding water can exist, which withstands better than other roof coatings. No erosion can occur when a roof has a silicone coat and won’t get hard or brittle.

Advantages of Silicone Roof Coating

One of the most significant features of silicone roof coating is the ability to suppress bonding water. The silicone coatings were formulated with solid substances that cannot absorb water after curing, enabling the roof to hold water for an extended period without breaking down its quality.

Flexibility: Roofs often get exposed to cold and hot temperatures, and they suffer contraction and expansion due to these climate changes. Roofs coated with silicone have a flexible membrane that enables them to maintain their quality and strength despite expanding and contracting due to climate change. The coating also allows it to withstand dirt particles blown to the roof.

Weather Resistant: Silicone roof coating can also resist extreme weather conditions such as heavy storms, downpours and snow and still be in good condition. This feature makes it an excellent choice when choosing a roofing material type.

Cost-Effective: Due to the white color of the silicone roof, sun rays are reflected, thus preventing the roof and the interior from being overheated. Due to this, the amount of energy consumed by air during warm seasons reduces the amount of money you pay for your energy bill.

Environmentally Friendly: Silicone roof coating is solvent-free and contains a high solid content and low Volatile Organic Compounds (VOCs). These compounds are known to be not inflammable and also, they are unstable; thus, these substances cannot harm the environment.

Highly Reflective and UV Resistant: The ability of the roof coating to reflect the UV rays enables a long-life span of the roof. It is also resistant to sun rays and cannot interfere with the quality, crack, or become so hard due to the prolonged exposure of sun rays. Most roof coating cannot overtake this ability of silicone roof coating.

High Solid Composition: The modern silicone coating roofs are intensely concentrated with solids. It results in less coating but achieves the thickness that you will desire to protect your roof. The maximum layer should be two, and this can provide a high level of protection your roof needs. The application procedure also will not require a lot of labor and is fast.

What to Do Before Applying Silicone Roof Coating

Power Washing: A roof must be thoroughly cleaned before coating it with silicone. Dirt accumulating on the roof surface can affect the quality and adhesiveness of the coating material. These are the following types of roof power washing: traditional power washer and reclamation washing.

Seam Reinforcement: Professionals always recommend seam fortification of the room before applying the coat. It helps the coating to last longer and adhere to the surface of a roof for a long time. Seam reinforcement is mainly done using coated polyester mesh and self-adhesive tape reinforcement.

Roof Repair: Most people refer to using silicone roof coating when the roof is leaking or aging. Therefore, roof repairs are considered before going on with the coating.

Strengths of Silicone

Silicone can stand against UV rays. It can reflect around 90 percent of the sun’s rays, which helps in reducing the burden of cooling the roofs thus lowering the electricity bill.

Silicone also contains solids that are highly concentrated, thus making them flexible and durable. It makes sure that with only a single coating, it will save both time, labor and money.

Does Roof Coating stop leaks?

A roof coating will possibly stop minor leaks but is not worth applying to identify the leaks. Identification of the leaks is important to repair before coating the roof.

Can You Paint Over Silicone Roof Coating?

Silicone caulk is designed to last longer and strong for areas that are exposed to water. The Silicone caulk is less prone to degrade than latex caulk or acrylic caulk and it resists mildew. It also adheres well while drying transparent.

How Long Does Silicone Roof Coating Last?

Silicon lasts for a long time. With the correct thickness of roof coating, good maintenance and annual inspection, a silicone roof coating can last for a decade.

Maintaining Silicone Roof Coating

Roofing maintenance begins with a visual inspection and reporting—looking for things that can damage the roof. Debris, wind, or access to foot traffic on the roof can cause damage to the roof.

Areas like drains, scuppers, and gutters should be maintained. A roofing contractor must make sure that the water is moving its designated way on the roof.


When applying a silicone coat to a roof, make sure that the roof is dry because any moisture on the roof will compromise the adhesion to the roof. If the previous roof was a dry cap sheet, it is good to apply two layers, the first one being a base coat of silicone following by a second coat.
