If you are currently looking for an efficient and affordable way to protect your commercial roof made from metal, EPDM, PVC, polyurethane, membrane, bitumen or some other type of BUR material to enhance its performance and to increase its longevity, you have probably come across roof coating products already. If you wish to know more about these great, modern roof protection solutions, here are some details from experienced commercial roofing contractors San Antonio TX has about the types they are available in and the purposes each of the types serves so that you can pick the product that best serves your goals.
Asphalt Coatings
These coating products contain asphalt particles and fillers to give the material its strength and they use clay as an agent for emulsification. Asphalt coating is available in a wide color palette that spans from dark shades, such as brown and black to white, making the material suitable not only for weatherproofing the roof surface, but also for enhancing the roof’s thermal performance – darker hues absorb solar heat, therefore they are more suitable for cold regions, while lighter shades, especially white, reflect the sun’s rays, keeping the entire roof cooler and reducing the energy necessary for cooling the rooms in the building.
Silicone Coatings
Considered by many experts to be the best coating type available today, silicone roof coatings are somewhat more expensive than other materials used for roof protection, but they are strong, durable, they offer a comprehensive solution and they are also biodegradable. What makes silicone stand out is its resistance to water, making it the best solution for roofs where ponding water is a problem. Like asphalt coatings, silicone coats are also available in many different colors, even white and translucent. The material can be applied from spray cans or rolled onto the roof without having to prime the surface first.
Polyurethane Roof Coating
Available in a wide range of colors, polyurethane coating is a popular choice for its affordability and durability. These coating systems usually consist of two layers, one that is durable and resistant to water, but sensitive to UV radiation and a top layer that is UV resistant.
Acrylic Roof Coating
These are the most affordable roof coating solutions, products that are easy to apply and provide efficient protection against solar radiation, but are not able to handle ponding water very well, therefore they are suitable for roofs in dry climate regions or for roofs that are not affected by the accumulation of water.
Butyl Coating
The features of the elastomeric material include high tensile strength and superior elongation capacities. It is a great choice for roofs in very cold as well as in very hot climate areas, its superior resistance to water and to UV rays (it is able to absorb as much as 80-90% of the sun’s rays) provides great, overall protection and it helps with the reduction of heating and cooling-related energy costs as well. The material forms an efficient vapor retardant barrier as well, making it suitable for being used on freezers and on other cold storage applications.
