Coating

While the terms are sometimes used interchangeably, they’re not necessarily the same. A roof sealant is a protective barrier applied to an existing roofing system to enhance the roof’s protection and seal cracks around chimneys, vents, flashing, and roofing materials themselves. A roof coating is a liquid barrier that becomes a new roof barrier membrane itself rather than enhancing the existing roofing system.

Roof coatings are designed to become a waterproof membrane that completely protects the building. If there are leaks, the damage should be repaired but the new membrane will prevent water penetration.

Generally speaking, elastomeric roof coatings are excellent at protecting buildings, but they do have some drawbacks. They’re generally not the most aesthetically pleasing roofing options, and they don’t always adhere evenly to the material below them. To ensure a perfect application, they require an expert’s touch like that of the pros at Nations Roof.

Yes, roof coatings are certainly worth it. They create waterproof barriers between the elements and the building, and they can help keep the building cool by reflecting the sun’s UV rays.

The expected lifespan of a roof coating is between 5 and 20 years, but it depends on the material type. Acrylic roof coating can last 5 to 10 years. Silicone roof coatings can last 10 to 20 years. Polyurethane coating can last 15 years or so. Elastomeric coatings have lifespans of 5 to 20 years.

Yes, roof coatings are walkable. However, acrylic coatings are better suited for light traffic while silicone and polyurethane can handle more traffic.

It depends on the material in question, but roof coatings can last 5 to 20 years before needing to be recoated. Stringent maintenance can help, but intense UV rays, harsh weather, and ponding water can lessen the roof’s potential lifespan.

Roof coating maintenance requires regular inspections including those by property owners and roofing professionals. Also, regular cleaning and prompt repairs are key to ensuring the roof coating lasts as long as possible.
