Types of Metal Roof Coatings and Their Purposes

Metal roofs are already strong and durable, but roof coatings can take their performance to the next level. Roof coatings can protect a metal roof from moisture, improve its appearance and increase its energy efficiency. Many roof coatings are factory applied, but some coatings can be applied after roof installation. YES Contracting Services, an experienced residential roofing contractor, talks about the various roof coatings used on metal roofs:

Reflective Pigments

Reflective pigments were first developed by the military to camouflage their tanks. Now this technology is used to make metal roofs more energy-efficient. Reflective pigments reflect a larger spectrum of sunlight than conventional pigments. A properly coated metal roof can reflect the sun’s heat away from the building. This can reduce the workload on the building’s HVAC systems, which can help reduce cooling costs.

Granular Coatings

Granular coatings or stone coatings look similar to asphalt shingle granules. They are used by metal roofs that have slate, tile and shake profiles. The stone coatings improve a metal roof’s appearance and allow it to match more kinds of home styles. Stone coatings can develop the same moisture-related microbial problems because they are similar to the surface of asphalt shingles. You should ask an expert in new roof installation and maintenance, like YES Contracting Services, to take care of your stone coated metal roof.

Barrier Coatings

Like stone coatings, barrier coatings are factory-applied. Their purpose is to protect metal from the catalyst that causes it to corrode, which is moisture. Paints are a barrier coating. There are three main paint-type coatings used in our metal roofing industry. Fluoropolymers are highly resistant to solvents and acids. They are similar to Teflon®. Polyesters are affordable and acrylic emulsions are environmentally friendly.
