Comparing Metal Roof Coating Options in BuffaloNov 05, 2018
Installing a Buffalo metal roof involves more than just metal. To create long-lasting, energy-efficient roofs, the experts at Erie Metal Roofs apply several types of materials to a roof’s surface for protection, impact resistance, style, and more. There are several kinds of metal roof coatings on the market, with each providing different benefits to the roof, and the home as a whole.
What Are Metal Roof Coatings?
Metal roofs contain three layers: the metal substrate, the metallic layer, and the exterior coating. Before the metal forms the roof profile, roofers apply the exterior coating for protection, color, and effective installation. Roof coatings comprise three components:
· Pigment, which is color for the exterior coating, changing the color and aesthetic of your home.
· Solvent, the liquid component of the exterior coating, provides resistance to sun, rain, snow, and other natural conditions that can wear down your metal roof.
· Resin, which acts as the glue that adheres the coating to the roof surface, and binds the pigment and solvent together to create the final coating. It provides chemical resistance and strength.
Thanks to the pigment in exterior coating, metal roofs can have versatile designs and come in a variety of colors. In addition, exterior metal roof coatings provide waterproof protection, energy efficiency, and element protection. Since metal alone traps heat so easily, a good exterior metal coating should offer heat resistance and low thermal conductivity.
Acrylic Roof Coatings
Acrylic roof coatings are water-based. Metal roofers will apply two separate coats of an acrylic roof coating due to its relative thinness when compared to other options. Acrylic coatings are the cheapest option available, but they do fade the fastest, requiring more maintenance. Agricultural buildings with metal roofs typically opt for acrylic coatings.
Polyester Roof Coatings
Polyester roof coatings are much higher quality than acrylic-based coatings. Unlike acrylic coatings, the metal only needs a single coat before roof installation. While polyester roof coatings last longer than acrylic coatings, they also tend to fade quickly. Polyester roof coatings are common on some agricultural metal roofs and on commercial metal roofs.
PVDF Roof Coatings
PVDF stands for polyvinylidene fluoride, and PVDF-based coatings are considered to be the best roof coating option in the metal roofing industry. PVDF coatings provide protection against UV rays, sun damage, water, humidity, high temperatures, rain, and oxidation, among other benefits.
These coatings last the longest, sometimes up to 30 years, and require little maintenance after application. They are lightweight and significantly heat-resistant, which is important for metal surfaces. Residential metal roofs tend to opt for PVDF-based coatings due to their long-lasting nature and simple maintenance.
