Will Your Commercial Roof Benefit from Roof Coating?

An economical compromise between tolerating a leaky commercial roof and paying for a whole new roof is an application of roof coating, expertly applied by your trusted local commercial roofer.

What is Roof Coating?

Roof coating is an additional layer of protection added to your existing roof. Suppose you have a concealed fastener (CF) standing seam metal roof on a 3-in-12 slope. Give it a roof coating to extend the metal roof’s service life. Tough, acrylic or silicone-based coatings can be sprayed on under pressure, so the liquid finds its way wherever water may have traveled. Your roof is sealed against water infiltration, while the metal gets additional rust prevention.

Many kinds of durable roof coatings are available, but at Jewett Roofing we prefer the class of coatings known as polymer-based roof coatings. We specialize in acrylic and silicone coatings.

What is in Roof Coating?

Five ingredients make up a typical commercial roof coating that St. Louis industry and commercial properties might use:

  • Binder—The substance that bonds all the other components of the roof coating together, such as acrylic and silicone
  • Pigments—These give the coating its characteristic color; titanium dioxide is commonly used to enhance UV resistance
  • Fillers—Materials that provide bulk and weathering surface to the coating
  • Modifiers—Materials or chemicals added to the roof coating to give the roof coating specific properties, like enhanced adhesion, viscosity or durability
  • Carrier—The liquid portion of the coating that evaporates from the coating once applied to the roof, leaving behind the solid roof coating

Benefits of Roof Coating

Roof coatings target the existing roof that is a little long in wear, but still has plenty of life in it. Roof coatings can seal a worn surface, prevent water infiltration ,and stop chemical breakdown of roofing plies. Coatings can add years of life. Roof coating is less expensive than a new roof. It is usually less expensive than a single-ply membrane laid over existing felts.

An added benefit of roof coatings is that it is reflective. A dark roof absorbs tremendous amounts of heat. That heat is conducted right through your roof deck into your building, making your cooling costs climb. The reflective coating can cut your energy bill.
