Silicone for Commercial Buildings
If you own a commercial building with a flat roof, you may want to consider a silicone roof coating. While these coatings are optional, they can help you end up with fewer roofing costs in the long run. However, they are usually best for certain situations. Here is more information about silicone roof coatings, their benefits, and their downsides.
What Is a Silicone Roof Coating?
Silicone coating is a highly flexible polymer roof material. You can find several different mixtures on the market. It starts as a liquid, and the roofer rolls it out or sprays it onto the roof. The silicone fills cracks and makes a tight seal. Some brands of silicone roof coating may require multiple coatings. Eventually, the silicone material cures and becomes a barrier to water and debris.
What Are the Benefits of Silicone Roof Coatings?
Silicone coatings provide a tough and protective barrier. Here are some of the benefits of a silicone coating on your commercial roof.
They Are Erosion-Resistant
Silicone roof coatings do not wear down with the elements. You won’t have concerns about premature roof wear and early replacement.
They Can Reduce Cooling Costs
Flat commercial roofs often get full sun exposure that could cause indoor temperatures to rise. Properly applied, the silicone coating will insulate your roof from the sun and keep indoor temperatures low.
They Are Environmentally Friendly
Silicone roof coatings are environmentally friendly in general. If you want to go further, then high-solid coatings are the best in this regard. These tend to have fewer volatile organic compounds and solvents.
They Are Resistant to Ponding Water
Once the material cures, you will find that it works well to protect your roof from water ponds on the flat surface. The roof can handle the water without the coating getting soft. However, this does not take the place of good roof drainage.
They Resist Mold and Mildew
Organic materials, like molds, mildew, and algae, don’t grow on the silicone material. You will spend less time with roof maintenance since you will not need to worry about organic materials degrading the roof.
They Apply Easily
Silicone roof coatings are easy to apply and don’t require a lot of time and labor to do it. You won’t have to worry about workers on your roof for long periods.
What Situations Are Not Ideal for Silicone Roof Coatings?
While silicone roof coatings have many benefits, they are not perfect for all roof situations. However, if you work with an expert roof contractor, they can minimize many of these issues. Here are some examples of the challenges of silicone roof coatings.
They Are Not Good For Slope Roofs
Silicone coatings don’t work well if you have a slanted roof such as those on most homes. If your roof has a steep slope, you may want to try a different coating like acrylic.
They Tend to Accumulate Dirt
Silicone coatings tend to accumulate the daily dirt and dust that settles on them. Over time, the dirt and dust will cause your roof to absorb more and more of the sun’s rays and will negate the coating’s reflective properties. Regular cleaning will keep this problem to a minimum.
They Aren’t Good for People to Walk On
If you regularly have people walk on your roof, you will need a modified version of the coating. Silicone coatings are slippery, especially when wet. However, you can mitigate this problem with a special silicone used to create a path for walking.
