Most roofing companies will give you a rough estimate of how long a roof will last. Unfortunately, in hot climates, roofs may only last half as long as they would in cooler climates. Here’s what you need to know about how heat and sun affect your roof.

Thermal Shock
Thermal shock happens when the roof is heated to extreme temperatures throughout the day and then it cools down quickly when the sun sets. This heating and cooling process causes constant contraction, which weakens the metal components of the roof as well as the shingles. The shingles will begin to warp and crack, which compromises the integrity of your roof because leaks will begin to form when the protective barrier created by shingles deteriorates.

UV Ray Exposure
Ultraviolet rays from constant sun exposure are another danger to your roof. This is especially true during the summer when the earth is closer to the sun. Just as UV rays damage and age skin, shingles age more quickly from UV exposure. They’ll begin to peel and cup, which allows them to lift from the underlying decking and be exposed to moisture.

Storms
Areas with both heat and humidity are exposed to the dangers of severe storms as well. Hail and high winds are common in these climates, so shingles will break or pull away from the roof.

If you suspect your roof is damaged by sun and heat, CM Roofing Pros can inspect your roof and determine the next course of action.
