Metal roofs are at the top when it comes to sheer durability and resilience. They can even outlast tile, a roofing material with a 100-year lifespan, as metal is more resistant to heat, rain and inclement weather.
These roofs last long as the metals used during construction are naturally durable. That said, the added coatings that are used as a finishing for the metal roof also play a key role in keeping the system as durable as possible. Renovation Team, your roof and vinyl siding installation experts, lists the three types of metal roof coatings.
Acrylic Emulsions
This is one of the three types of paints used to coat metal roofs and is the most popular. They are water-based and environmentally friendly, applied using a primer and top coat. Acrylic emulsions give the metal a textured look. While purely for aesthetics, this paint helps the metal roof resist heat from the sun.
Barrier Coatings
These deprive the new roofing system of the catalyst it needs to corrode and is essentially a rust preventing coating. The aforementioned acrylic emulsion is a standard barrier coating, but you aren’t restricted to just that.
Polyesters and fluoropolymers are good alternatives that act as a durable and long-lasting barrier coating for the metal roof. While they are subject to eventual fading and chalking, they are easy to apply.
Granular and Reflective Pigments
Granular coatings are made from crushed stone and give the metal roof an asphalt shingle appearance. It also enhances the material’s innate durability and helps make a metal roof more resistant to dents and bruises. Reflective pigments, on the other hand, are a recent development and are often used in conjunction with granular coatings. They help make the roof even cooler by reflecting heat from the sun.
