Roof coatings are great for commercial properties. They help protect commercial roofs from UV and water damage, prolonging their lifespan. What’s more, certain roof coatings help lower energy costs and minimize the need for repairs.
There are various types of roof coatings available, each with strengths and weaknesses. As a trusted roof installation contractor, Affordable Roof Care is here to help you choose the right material for your needs. Here’s a quick guide.
Acrylic is a cost-effective coating material that may be water or solvent based. It is relatively affordable compared to other materials, while still being highly reflective and UV resistant. In addition, it can stand up to a variety of weather conditions.
Acrylic doesn’t do well against ponding water, however, and tends to lose its thickness with weathering.
There are two types of polyurethane coatings: aromatic, usually used as base coating, and aliphatic, used atop aromatic coating. Aromatic coatings don’t do well on their own and require aliphatic coatings to form a strong barrier that can handle impact and foot traffic .
Combining the two polyurethane coatings results in a durable coating, but also results in a higher cost compared to acrylic coatings.
Asphalt roof coatings are good against various weather conditions, are reflective and are UV-stable. They usually come in black or aluminized emulsions, and are best used on asphalt-based or bitumen roofs.
Asphalt emulsions are water based and are sensitive to moisture and need to cure before being exposed to water. Exposure to moisture can affect reflectiveness and waterproofing. It is best to install this type of coating during warm to hot weather conditions.
Unlike asphalt, silicone coatings are moisture cured and can be applied even in humid weather conditions, as humidity can promote curing. Silicone is good against water ponding and doesn’t become brittle.
Over time, however, silicone loses its ability to reflect sunlight. Roofers might also need to replace the whole coating entirely as silicone is hard to adhere.
