Arizona is well-known for its hot summers. With multiple months averaging over 100 degrees Fahrenheit, the sun’s ultraviolet rays can be intense for people and buildings alike. When it comes to your home’s roofing, the combination of high temperatures and constant sun can really do some damage. Take a look at just a few kinds of damage your roof can sustain this summer.

3 Ways Heat Can Damage Roofing

1. Decay

Especially in older roofs, sunlight can speed up the decaying process. In general, asphalt shingles have a lifespan of approximately 20 years. Shingles naturally begin to break down and deteriorate with age, and this is exacerbated by the damaging effects of UV rays. If your roof is older than 15 years, you may begin to notice missing pieces or warping. 

roofing2. Thermal Shock

Because Arizona is a desert environment, it is extremely hot in the sun and cool during the nighttime. These shifts in temperature can cause roofing materials to expand and contract rapidly. Over time, this movement weakens the structure. Metal, in particular, is at risk of this form of damage. 

3. Cracking & Leaking

High heat levels can quickly dry out roofing materials and cause shingles to become brittle, hard, and inflexible. This inflexibility has a much harder time holding up to winds, storms, or flying debris, making the materials far more likely to crack or break when faced with force. Replace dried-out shingles as needed to prevent this type of damage from happening.
