Albuquerque sees about 278 days of sun a year. Unfortunately, the abundant sunshine leaves roofs susceptible to heat damage. Asphalt shingles, in particular, turn inflexible and brittle when they are exposed to heat for prolonged periods of time. They also tend to curl, crack and lose their original color over time. Fortunately, you can avoid such issues by raising the reflectivity of your roof.
Reflectivity and heat damage
Reflectivity refers to the ability of a roof’s surface to redirect rays from the sun. The more reflective a roof is, the more solar energy ‘bounces’ off the surface, resulting in less heat absorbed. Experts claim that a surface must have a reflectivity rating of 65% or greater if homeowners wish to enjoy the benefits of a reflective roof.
How is this achieved? Typically, a white coating with special reflective pigments that reflect sunlight is applied to the roof’s surface. The coating is like a thick paint that can shield the roof from UV and chemical damage, among other benefits. Likewise, those who have yet to have their house built or would like to replace their existing roofing system can take advantage of roofing materials with built-in reflective qualities.
Benefits of improving roof reflectivity
Not only do reflective roofing materials divert heat away and prolong the lifespan of a roof, but they also help keep a home cool during the warmer seasons. As a result, cooling systems consume less energy, leading to lower energy bills.
New Mexico sees about the same amount of sunlight during fall as it would see during summer, making today a good time to improve the reflectivity of your roof.
