Silicone roof coating is a substance, which is directly sprayed onto an existing roof system. This type of coating is also known as silicone restoration membrane as it forms a protective layer on the roof. The best thing about silicone roof coating is that it fills in seams, cracks, and blisters on commercial roofs. This system ultimately enhances the durability of the building’s roof as it guards against climate and elements like UVA and UVB. It is also able to withstand hails, rain, winds, snow, etc. Silicone roof coatings ensure to offer maximum protection if it is installed properly.
There is no denying that it is the best solution to restore and protect the commercial roof, but it has its own pros and cons. Let us discuss them one by one so that you can make a wise decision.
Many people count on silicone roof coating as it has several benefits, which are as follows:
Pros of Silicone Roof Coatings
1. Reduced energy expenses
Silicone roof coating has reflective capabilities and reflects maximum ultraviolet rays. Because it is installed in a bright white color, it is referred to as a cool roof. This system keeps the building at a comfortable temperature. The building can then save up to 35% in energy costs in the warmer months by reducing air conditioning usage.
2. High flexibility
This type of roof coating can endure thermal movement (natural expansion and contraction) over different temperatures for a long period of time. It has a high tolerance to thermal differences. This feature makes silicone roof coatings highly flexible. Meaning, the coating creates an impermeable membrane that can withstand oxidation and extreme temperatures, which take place in big roof areas. The key part is, it does not become brittle.
3. Extends the roof lifespan
Silicone coating extends the life of the roof if it is applied to a roof that is in relatively good condition. It is applied as a liquid, and therefore, it can fill in any vulnerable areas such as cracks, seams without the need for any extensive labor. This coating helps keep the water away as it offers extra layers of protection on the problematic area.
4. Savings on preparation and installation
The preparation and installation of silicone roof coating require minimal expense if it is sprayed on the roof that is dry. That means you can experience a substantial level of cost savings as it can be installed swiftly and does not involve the removal of the existing roof. Also, installing a new silicon coating can make your roof sturdy and waterproof as well. The bonus you get is-it does not interrupt the regular functions of the business.
5. Cures naturally outdoors
It does not require any special arrangements as it cures naturally when exposed to moisture. It is usually installed in the hot season when the humidity is high. In fact, at such times, this coating does not require a primer in some cases.
Cons of Silicone Roof Coatings
Now, let’s discuss some of the common issues with silicone roof coatings.
1. Replacing it is hard
You would need to remove the complete surface when you wish to replace it. It would be the hardest and challenging part. You will have two options- either you employ the products that work well with the present roof surface or remove the last silicone roof coating completely. In both cases, you’ll have to pay more. Removing the silicone coating is a labor-intensive process, which makes it expensive.
2. Loses its reflectivity over time
It attracts dirt and dust, which build up on the surface and cause it to lose its reflective property. Due to this, the roof becomes prone to thermal heat, which drastically impacts the internal building temperatures. Apart from dirt, rain also washes away the layer. Therefore, it will lose reflectivity over time. Clearly, these factors will lead to a rise in cooling and heating bills, and the bills will keep rising once the silicone coating loses its reflectivity.
3. Slippery surface
Silicone is not at all durable, and it lacks abrasion, which makes it easy to tear. Moreover, the roof tends to be more slippery when it becomes wet. So, the areas that have high foot traffic need proper maintenance. A professional roofing contractor can add sand during application as it will provide strength and more stability as well as a safe area for walking.
4. Difficult to spray
The equipment used for the application has to be cleaned properly; otherwise, issues will pop in during the installation process. This type of roof coating can be challenging to spray as they are tough on hydraulic spray equipment.
5. Requires proper installation
Silicone roof coating application should be done by an expert professional. This type of solvent-based coatings is not easily applied with spraying tools. So the roofing contractor has to use clean and well-maintained equipment to ease the application process. Some contractors may use rollers as they provide an efficient application.
