Roof damage caused by UV rays from the sun runs deeper than you think. UV degradation happens when the protective layer of your roof is altered molecule by molecule until it completely disintegrates. Constant exposure to UV rays can break down even the most durable of materials like asphalt shingles, for instance. UV degradation is just one of the many consequences of constant exposure, however.
You can prevent your roof from the effects of the sun by applying elastomeric acrylic coatings to your roof. Allied Construction Services, a top commercial roofing contractor in the state, shows you how these coatings can protect your roof.
UV Degradation and Heat Contraction
The alteration of the chemical composition of your roof can lead to the following:
There’s another way the sun can damage your roof, however, and that’s heat contraction. When the sunlight hits the surface of your roof, it heats up and expands. As the sun sets, the surface cools down and contracts. Thermal shock, this constant cycle of expansion and contraction, eventually causes cracks to form on your roof.
Elastic and Reflective Roof Coatings
Companies specializing in commercial construction services recommend the application of elastomeric acrylic coatings to your roof to help it endure thermal shock. Roof coatings are usually white in color and have UV-blocking properties. The white color reflects up to eighty-five percent of the heat from the sun, reducing thermal shock to your roof.
Thanks to the elastic properties of roof coatings, they’ll be able to deal with the heat that doesn’t get reflected. Roof coatings’ elasticity allows them to contract and expand with your roof, making sure the protective layer doesn’t tear in the process.
Roof coatings are just one way of protecting your roof against UV degradation, however. You can hire a company specializing in roofing construction services to install a roof replacement made of UV-resistant materials, like metal.
