Asphalt shingles are found in a typical residential sloped roof. As these shingles age, they become increasingly susceptible to wear from UV rays. How can sun rays cause damage? More importantly, what can you do as a Mill Creek homeowner to offset the wear?
How Do UV Rays Damage Asphalt Shingles?
UV rays cause the shingles’ outermost layer to dry up. As time goes by, this can lead to cracking, fractures, and warping. UV light can alter the material’s chemical structure. The elevated heat also causes the asphalt’s oil to evaporate, leading to brittleness.
Moreover, shingles are also more susceptible to thermal shock when it’s sunny. This stems from the continuous flux between the daytime heat and nighttime cooler temperatures. This causes a back-and-forth expansion and contraction, leading to the shingles pulling away.
How to Minimize UV Ray Damage
Many contemporary asphalt shingles come with a solar reflective coating to offset degradation. However, even with this additional protection, the coated granules may still separate after long-term exposure to precipitation.
This is why yearly roofing surveys are recommended. This is especially so if you spot traces of granules in the gutters or downspouts. This is an indicator the coating is coming off, leading to exposed asphalt.
Other prevention measures may include incorporating more attic insulation. Without sufficient insulation, the heat accumulated in the home interior can pass through the attic and impact the shingles. The same applies to the ventilation. Adequate ventilation keeps humid air from accruing in the attic.
