Chandler, Arizona
Roof rejuvenation in Chandler
Most of Chandler’s homes have tile roofs, but about 16,400 have asphalt shingles, nearly all of them in north and west Chandler. ShingleGuard’s bio-based treatment is designed to replace the oils those shingles lose to the sun, so a qualifying roof can keep doing its job instead of being torn off early.
Shingle roofs in the north, tile in the south
Chandler’s shingle roofs sit on its older homes, north of the newer, mostly tile neighborhoods to the south. Nearly all of them have been through more than 30 Arizona summers.

Chandler’s shingle roofs date from its first big boom
Six in ten of Chandler’s shingle-roof homes were built in the 1980s, as the city grew out from its downtown, and another fifth in the 1970s. In south Chandler ZIP codes 85248, 85249 and 85286, fewer than 1 home in 20 has shingles.
A roof from the 1980s has been through some 40 Arizona summers, so most homes from that era have been re-roofed at least once. The shingles you have now may be much younger than the house. A free assessment checks how flexible they are, how well the granules are holding, and whether the roof is still sound.

What Chandler does to asphalt shingles
Every asphalt roof ages. Here, it happens faster.
More than 100 days a year at 100°F or hotter
A typical Valley summer brings more than 100 days at 100°F or above. Heat drives the oils out of asphalt shingles, so they dry out, stiffen and start to shed granules.
Strong sun, winter included
Sunlight breaks down asphalt at the surface, and in the desert it shines nearly every day of the year. The granules on a shingle are its sunscreen. As they wear away, the asphalt underneath ages faster.
Monsoon season, June 15 to September 30
Summer storms bring sudden wind, dust and heavy rain. Shingles that have gone brittle are the ones most likely to crack, lift or shed granules when a storm comes through.
Rejuvenation fits some roofs, not all
We’ll tell you honestly after a free assessment. Here’s a quick way to gauge your Chandler home before we visit.
Usually a good fit
- An asphalt shingle roof on a single-family home, common in north and west Chandler
- Shingles that look faded, dry or chalky, or granules collecting in gutters and at downspouts
- A roof that is aging but still sound, with no active leaks
- You want to put off the cost and hassle of a full replacement
Usually not a fit
- Tile roofs (most of south Chandler), metal, foam or flat roofs
- Active leaks, soft decking or water stains on the ceiling
- Many missing, torn or badly curled shingles
What a new roof costs in Chandler
A typical Chandler shingle-roof home has about 2,000 sq ft of roof, so replacing it runs roughly $8,000 to $14,000 in 2026.
Chandler’s shingle-roof homes are the smallest of the Valley cities we cover, with a median of about 1,450 sq ft of living space. Only 2% have 2,500 sq ft or more, so most replacement bids here land in the lower half of the Valley range.
If your roof is aging but still sound, rejuvenating it runs about $2,000 to $2,500, tune-up included, and can put that bill off.

A simple, three-step process

Free roof assessment
We inspect your shingles up close, checking flexibility, granule coverage and any damage, then tell you honestly whether rejuvenation makes sense.

Protect & tune up
On treatment day we protect landscaping, pools and surfaces, then tune up the roof: Perma-Boot covers on the vent pipes, a few replacement shingles, resealed vents and flashing, and clean gutters.

Rejuvenate
We apply our bio-based treatment evenly across the shingles, where it is absorbed into the asphalt to replace oils lost to age, sun and heat. It's typically dry within about an hour.
A treatment with real credentials
We chose our rejuvenation treatment because it's backed by certification, independent testing and published research, not just marketing.
USDA Certified Biobased
Certified through the USDA BioPreferred program, with 96% biobased content from renewable sources rather than petroleum.
Patented formula
Protected by a U.S. patent issued in 2025 for treatments that improve aged, brittle asphalt binders.
Independently lab-tested
Tested by an independent asphalt testing laboratory in 2020, 2021 and 2024, showing improved shingle flexibility and better granule adhesion.
Untreated shingles shed nearly 2x the granules
In independent lab testing on 13-year-old shingles, untreated shingles lost 13.2% of their granules, nearly twice the 7–8% lost by treated shingles.
Class A fire rating maintained
In independent ASTM E108 fire testing, treated roofs kept their Class A fire rating, and flame spread was slightly reduced.
University research, peer-reviewed
Developed from Iowa State University research, with results published in a peer-reviewed asphalt technology journal in 2025.
Bonds with aged asphalt
University lab analysis showed the treatment chemically reacts with aged asphalt, rather than just softening it the way a plain oil does.
Flexibility restored to nearly new
In Iowa State University testing, treatment brought shingles from roofs more than 15 years old back to nearly new flexibility.
Clean runoff, near-zero VOCs
Water-based with no odor. Independent testing measured just 0.02% VOCs and found no detectable PAHs or PCBs in rain runoff from treated shingles.
Results on any individual roof vary with its age and condition.

Not with rejuvenation. It’s made for asphalt shingles only, and tile roofs wear out in a different way. If your home is one of the shingle roofs in south Chandler, we’re glad to take a look.
Not necessarily. Most homes from that era have been re-roofed, so the shingles may be much younger than the house. What decides it is the condition of the shingles today: flexibility, granule coverage and soundness. The free assessment checks all three, and if the roof is past the point where treatment helps, we’ll tell you.
Soon. We ask that people and pets stay clear of the roof and the area right below it until the treatment is dry. In warm, dry weather it is typically dry to the touch in about 30 minutes, ready for foot traffic in about an hour, and fully cured within 1 to 2 hours in warm, dry weather. The treatment is water-based with no odor and designed for safe use around homes.
Yes. We serve all of Chandler, from downtown and west Chandler to Ocotillo and Chandler Heights, plus the rest of the Phoenix Valley. Call or text 480-283-4560 to schedule a free assessment.
