Arizona roof protection
The desert is tough on asphalt shingles
Arizona's heat, sun and monsoon storms put asphalt shingle roofs through more than most climates. Here's what that means for your roof, and how maintenance and rejuvenation may help protect your investment.
Four forces that age Arizona roofs
Every asphalt roof ages. In the desert, several factors work together to speed that process up.
Intense UV exposure
Arizona sees some of the strongest, most consistent sunshine in the country, with summer UV index readings that regularly reach the "extreme" range. UV breaks down the asphalt in shingles over time, especially where granules have worn thin.
Extreme roof temperatures
The Phoenix area averages more than 100 days a year at or above 100°F. On sunny days, a dark roof surface can get far hotter than the air, and the U.S. Department of Energy notes that conventional roofs can reach 150°F or more. Heat accelerates the loss of oils from the asphalt.
Daily heating and cooling
Desert temperatures can swing widely between afternoon and night. Each cycle makes shingles expand and contract. Flexible shingles handle this movement well; brittle ones are more likely to crack.
Monsoon season
From mid-June through September, monsoon storms bring sudden high winds, heavy downpours and blowing dust. Dry, brittle shingles are more vulnerable to lifting, cracking and granule loss when storms hit.
A simple roof care checklist for Arizona homeowners
- Look for granules collecting in gutters and at downspouts
- Check for faded, dry-looking or cracked shingles from the ground
- Keep gutters and roof valleys clear of debris before monsoon season
- Make sure attic ventilation is working, since trapped heat ages shingles from below
- Trim branches that rub against or overhang the roof
- Have your roof assessed every few years, and after major storms
Maintenance keeps roofs clean. Rejuvenation addresses what the sun takes.
Routine maintenance can't put back the oils your shingles have lost. For a qualifying roof, rejuvenation is designed to replenish them, which may help your shingles stay flexible through Arizona's heat and storms and extend the roof's useful life.
