Among all the chemistry-type materials used in roof renovations, a silicone roof coating is considered as one of the most durable and prominent options. 

You can apply this coating to a diverse range of commercial buildings such as in modified bitumen or metal roofs, roof decks, EPDM, single plywood, and many more.

Before you decide to apply this coating on your roof, you should have a brief idea about this material. Henc, you have to know silicone roof coating pros and cons and decide whether it is a good decision for your roof.

Let’s briefly discuss the pros and cons of this coating and its impacts.

What is Silicone Roof coating?

Silicone roof coating is a coating of single or multiple layers of rolled silicone or a coating of liquid silicone being sprayed on the roof. It provides an additional layer of protection to your roof along with covering it from cracks, damage, or blisters.

Silicone Roof Coating Pros and Cons

As a homeowner or worker, it is very important for you to decide the right coating for your roof that satisfies the purpose of it, protects the roof, and is also durable.

Like any other coating, silicone coating also has some pros and cons associated with it. 

Pros of Silicone Coating

UV protection:

During the daytime, silicone roof coating provides protection from the ultraviolet rays ( UVA and UVB) of the sun. Research shows that almost 80 to 90% of the sun’s UV rays are reflected by this coating. So, it is indeed a very good side of silicone coating that protects that roof as well as the whole house.

Reduction of Energy Expenses:

The reflective capability of the coating also helps to reduce the energy and maintenance cost. As many sun rays are reflected, the thermal energy is not trapped inside the house which eventually reduces the consumption of air conditioning on hot summer days. It is said almost 35% of energy costs can be saved in this way. 

Water resistance:

The most amazing benefits of silicone roof coating lies in its resistance to ponding or puddling water. 

The coatings are mainly moisture cure materials which means after the whole curing process, silicone coatings will not absorb any water. So, they can handle ponding water damages. It basically works as a sealant and prevents water leakage to damage the roof.

Extending the lifespan of your roof:

As the product is applied in liquid form, it can create maximum coverage on your roof. All the cracks, blisters, and seams receive an extra layer of protection from water, snow, and other weather conditions. And this will increase the lifespan of your roof.


The internal components of silicone coatings are almost all organic and environmentally friendly compounds. So, the coatings are approved by all the safety standards. The coatings are solvent-free and also do not degrade to any material that can harm the environment.

Cons of Silicone Coating

Tendency to get dirty

Silicone roof coating easily gets dirty and attracts other dirt particles. Over time, the layer gets thicker. It reduces the efficiency of your roof and the reflectivity property of the coats. Normally, washing with pressurized water can solve the dirt problem.

Challenging to apply

The applying technique of liquid silicone is by spraying. Now While spraying, you have to make sure that you wear a proper mask, gloves, boots, and other safety equipment. Lack of experience can cause uneven layering of coats as well as accidents. So, be careful when applying the coating.

Slippery when wet

Coatings can be extremely slippery when wet. If you walk on a wet surface, it is most likely to slip. So, try to avoid that. If you need to do urgent maintenance work, make sure to wear boots or heavy gripped shoes. Otherwise, you may fall on or can cause serious injuries.

Final Words

Although there are some disadvantages of silicone roof coatings, the probabilities where they can be used are also endless. Before taking any decision, analyze your roofing condition, budget, durability, and other factors and then make the choice.

In case of any confusion, consult a professional who can help you in this context.

Hopefully, this article has helped you have an overall idea about silicone roof coating pros and cons. And now, you can make your choice to use it on your roof or not.
