Asphalt shingle roof repair and replacement
Shingles are a cost-effective, good-looking roof for many Valley homes. We repair wind and heat damage and install new shingle roofs built to handle the Arizona sun.

The short answer
Asphalt shingle roofs typically last about 15–25 years in Arizona, where heat and UV wear them faster than in cooler climates. Signs of a failing shingle roof include curling or cracked shingles, bald spots, heavy granule loss in gutters, and wind-lifted or missing tabs.
Shingle repairs
Monsoon winds can lift and tear shingles, and summer heat can make them brittle. We replace damaged shingles, reseal lifted ones, and repair flashing and vents so water stays out.

Shingle roof replacement
When your shingles are worn out, we tear the old roof off, inspect and repair the deck, and install a new shingle system with new underlayment, flashing and ridge caps. Lighter colors and good attic ventilation help shingles last longer in Arizona.
How an asphalt shingle works
A modern shingle is a fiberglass mat soaked in asphalt and topped with ceramic-coated mineral granules. The asphalt sheds water, and the granules shield the asphalt from UV and give the roof its color. A strip of sealant on each shingle bonds it to the one below once the sun warms it.
Underneath, an underlayment adds a second line of defense, and flashing seals the edges, valleys, walls and vents. A shingle roof is only as good as those details.
Heat, UV and granule loss
Arizona sun slowly cooks the oils out of the asphalt. As it hardens, shingles get brittle, curl at the edges and crack. Granules loosen and wash into gutters, and once bare asphalt is exposed, UV speeds the damage even more.
That's why shingle roofs here often fall toward the shorter end of their rated life. A balanced attic ventilation system and a lighter color both help slow the process.
Ventilation and attic heat
A hot, poorly vented attic heats shingles from below while the sun heats them from above. Good ventilation pairs intake vents low on the roof, usually at the soffits, with exhaust vents near the ridge, so hot air keeps moving out.
During a replacement we check that intake and exhaust are balanced and that vents aren't blocked by insulation. It's one of the simplest ways to help a new shingle roof last.
Three-tab vs architectural shingles
Three-tab shingles are a single flat layer with a uniform pattern. Architectural (dimensional) shingles are made of laminated layers, so they're thicker, have a more textured look and generally hold up better to wind. Most new shingle roofs today use architectural shingles, and many HOAs prefer or require them.
Shingle maintenance checklist
A few simple habits help a shingle roof reach its full life.
- Check from the ground for lifted, creased or missing shingles after monsoon storms
- Look for granules piling up at downspouts
- Keep gutters and valleys clear of leaves and debris
- Trim tree limbs that rub or drop debris on the roof
- Watch ceilings and the attic for stains after heavy rain
- Schedule a roof inspection as the roof passes 15 years
Frequently asked questions
Still have a question? Call the office at 602-548-3770, Monday to Friday, 7 am to 5 pm.
How long do asphalt shingles last in Arizona?
Typically about 15–25 years, depending on the shingle quality, color, attic ventilation and exposure. Heat and UV shorten shingle life compared with milder climates.
What are signs my shingle roof needs replacing?
Curling, cracking or brittle shingles, bald spots, granules piling up in gutters, multiple leaks, and a roof that's near the end of its expected life.
Can a few shingles be replaced after a storm?
Yes. Wind damage to a handful of shingles is usually a simple repair, as long as the surrounding shingles are still in good condition.
Are dark shingles bad in Arizona?
Darker shingles absorb more heat, which can raise attic temperatures and speed up aging. Lighter colors reflect more sunlight. Many homeowners balance appearance with heat performance.
Why are there granules in my gutters?
Some granule loss is normal on new shingles. Heavy, ongoing loss on an older roof means the shingles are wearing out and losing their UV protection.
Can new shingles go over my old ones?
Building codes generally allow a limited number of layers, but we recommend a full tear-off. Removing the old roof lets us inspect and repair the deck, replace the underlayment and flashing, and avoid trapping heat and extra weight.
Should I choose three-tab or architectural shingles?
Architectural shingles are thicker, more wind-resistant and have a more textured look, so they're the usual choice today. Three-tab shingles are thinner and less common on new roofs.
How does monsoon wind damage shingles?
Strong gusts can break the sealant bond and fold shingles back, leaving a crease or tearing them off. Creased shingles may look flat afterward but no longer seal properly, so they should be checked and replaced.
Can a shingle roof be replaced with tile?
Sometimes. Tile is much heavier, so the framing must be able to carry it, and an engineering review may be required. We can explain what's involved for your home.
How much does a shingle roof cost?
Every roof is different. Size, pitch, shingle type, layers to remove and deck repairs all affect the price. Our Roofing Cost Guide at /resources/roofing-cost-guide/ explains the main factors.
Can solar panels go on a shingle roof?
Yes. Shingle roofs are one of the simpler roofs for solar mounts, which are flashed into the shingles. If the roof is past its middle years, consider replacing it before panels go on.
