UV radiation is known to damage the skin, but did you know it can damage your roof too? Most of your roof, if not all of it, is exposed to the sun all day and this can change the components of the roofing material.

UV Radiation and Your Roof: What You Need To Know

The Effects of UV Rays

Shingles are durable and look great, but this will not be the case after overexposure to the sun. Deep within the shingle, the UV light alters the chemical makeup. Typically shingles have a protective coating but the hydrocarbons in this coating deteriorate as they contact the air. The heat from the sun accelerates this deterioration. The result over time is cracking and peeling. You may not always see the long term damage but it will be there. As cracking expands, any water and moisture from other seasons will only make the situation worse. The heat is just as damaging as the light because it increases expansion. When the asphalt cools at night, even more cracking can occur. This thermal shock is the number one cause of shingle destruction. Even though asphalt is more susceptible to sun damage, all types of roofing can be damaged by excessive sun exposure.

Prevention

So what can you do? Regular inspections of your roofing can help to prevent serious damage. Hire an expert to check your roofing at least once a year. Remember that rain and wind can loosen shingles leaving the roof more exposed to the sun. If your shingles are in good shape, applying a protective coating can help preserve them. By reflecting the sun’s light and heat away, you can give a little more life to your shingles. You can also install a metal roof that is better able to withstand expansion and contraction and does not get changed at the molecular level. Rubber roofing is also impervious to UV rays.
