There are many options out there when it comes to roofing materials. The choice you make will impact the longevity of the roof as well as your energy costs. One of those options is silicone roofing, an option that is often forgotten. Before you start any roofing project it is important to know all your options, so here is everything you need to know about silicone roofing.

All You Need To Know About Silicone Roofing Systems

What Are Silicone Roofing Systems?

Silicone roofing is a coating applied to existing material. It essentially creates a new roof for added protection. With a silicone coating, you get a seamless membrane that protects against sun and rain, but you need to apply it with a primer for the best coverage. You cannot use silicone as a stand-alone roofing option. It must be applied over another material. Silicone roofing is a great option for older roofing to expand the lifespan or to strengthen a new roof made of another material.  Installing a silicone roofing system is pretty simple. An infrared inspection identifies saturated areas of insulation that need to be removed. The roof is then power washed and cleaned. The primer is installed and the membrane seams are reinforced. The final step is to spray on the silicone coating. It can also be rolled across the existing roof.

The Pros of Silicone Roofing

  • Save Money: Using a silicone coating saves money because you don’t have to tear off and replace a roofing system. You will pay between $2 and $4 per square foot for silicone compared to as much as $10 per square foot for complete roof removal. You just need to make sure the existing roof is stable and dry. Any areas that need to be replaced can be taken care of before the silicone is applied.
  • Roof Longevity: Adding a silicone coating can extend the life of a roof that is in fairly good condition. It adds extra protection from the elements and can fill any cracks or weak areas in your roof.
  • Lower Energy Costs: Silicone roofing is referred to as ‘cool’ roofing because it helps keep the internal building temperatures cool. The coating is white so reflects heat away from the building, reducing energy use by 35%. You will not need as much A/C so can lower your utility costs.
  • Quick Installation: One of the biggest dreads with roofing projects is the time it takes to complete and disruption to the day. With silicone roofing, you get the job done quickly with minimal disruptions and fewer labor costs.

The Cons of Silicone Roofing

  • Adherence Issues: There is a reason people say that the only thing that sticks to silicone, is silicone. Once it comes time to replace the roof again, you will need to remove the silicone before you can install a different roofing system. When you go with silicone roofing, you are making a long-term investment.
  • Eligibility: Not all roofing is eligible for silicone coating. To get silicone coating your roof must be less than 25% saturated, have decent seams, and be properly maintained every year. If there are any leaks already present, silicone roofing will not work.
  • Expertise Required: Spraying a coating seems easy and it is compared to other roofing methods. However, if not applied properly, the silicone coating will not be effective. You need to discuss with a professional if the roof should be rolled or sprayed if the primer is needed, and how thick the coating needs to be. Proper application is the difference between your roof lasting a few months or 20 years.
  • Application Smell: Silicone has a strong, unpleasant smell as it cures, so it needs to be applied in a well-ventilated area. The good news is that the smell doesn’t last long, but you may want to make sure all building tenants are out of the zone during application.
