In the realm of commercial roofing, coatings are often applied to extend the lifespan of roofs, improve their appearance, and enhance their energy efficiency. This article will delve into the various prevalent types of roof coatings used in commercial settings.
Acrylic Roof Coatings
Acrylic roof coatings are highly favored due to their durability and cost-effectiveness. These coatings are water-based and, thus, environmentally friendly. Ultraviolet rays from the sun are effectively reflected away by these coatings. This results in a reduction in energy costs. However, it should be noted that acrylic roof coatings are more susceptible to wear and tear in areas with heavy rainfall or high humidity.
Silicone Roof Coatings
Silicone roof coatings are known for their superior weather resistance. Unaffected by the sun's ultraviolet rays, these coatings remain flexible and do not become brittle over time. Ponding water, a common issue on flat roofs, is well-tolerated by silicone coatings. Despite the higher initial cost of silicone roof coatings, their longevity and durability often offset the expense.
Polyurethane Roof Coatings
Two types of polyurethane coatings are commonly used: aromatic and aliphatic. Aromatic coatings, which are less expensive but not as UV stable, are usually used as a base coat. Aliphatic coatings, on the other hand, are UV stable, hold color well, and resist dirt pick-up. They are often used as a topcoat due to these properties. Polyurethane coatings are known for their high tensile strength and ability to withstand foot traffic, making them an excellent choice for roofs with heavy equipment.
Asphalt Roof Coatings
Asphalt roof coatings, also known as cutback coatings, are made of asphalt dissolved in a solvent. This allows easier application. They are available in black or an aluminum-finish reflective coating. It must be highlighted that while asphalt coatings are easy to apply and economical, they do not offer the same level of UV protection as other coatings.
Elastomeric Roof Coatings
Elastomeric roof coatings are renowned for their flexibility and elasticity. These coatings can expand and contract without damage, making them ideal for climates with significant temperature fluctuations. Elastomeric coatings provide excellent waterproofing and UV protection. This contributes to their popularity.
In conclusion, a variety of commercial roof coatings are available, each with advantages and potential drawbacks. When selecting a coating, it is important to consider various factors, including the climate in your area, the type of roof, and the unique requirements of your building. By understanding the different types of coatings and their properties, informed decisions can be made, ensuring that the most suitable commercial roof coating is selected for the specific situation.
Roofers have a tough job. They work at heights, carrying heavy shingles and nailing them to the roof's surface. In addition to working hard, roofers are also very knowledgeable.
