Mesa, Arizona
Roof rejuvenation in Mesa
Outside Phoenix itself, no city in the Valley has more asphalt shingle roofs than Mesa: about 55,600 single-family homes, most of them built in the 1970s and 1980s. 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.

Tens of thousands of aging shingle roofs
West and central Mesa are mostly shingle. The newer neighborhoods to the east are mostly tile. Across the city, county records show a huge number of shingle roofs that have been through decades of Arizona summers.

Most of Mesa’s shingle roofs came with the boom years
Seven in ten of Mesa’s shingle-roof homes were built in the 1970s and 1980s, as the city grew out from downtown in every direction. In west and central ZIP codes like 85202, 85204 and 85210, more than 80% of single-family homes have shingles. In 85207, on the city’s east side, fewer than 1 in 4 do.
A home built in 1978 has been through more than 45 Arizona summers, so it’s almost certainly on its second roof or later, and the shingles on it may be much younger than the house. That’s why we judge the shingles, not the house. A free assessment checks how flexible they are, how well the granules are holding, and whether the roof is still sound.

What Mesa 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 Mesa home before we visit.
Usually a good fit
- An asphalt shingle roof on a single-family home, common across west and central Mesa
- 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 newer homes in east Mesa), 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 Mesa
A typical Mesa shingle-roof home has about 2,100 sq ft of roof, so replacing it runs roughly $8,500 to $14,500 in 2026.
Mesa sits right at the Valley middle. The typical shingle-roof home has about 1,550 sq ft of living space and a garage or carport, and only 5% are two stories. Single-story roofs are faster and safer to work on, which helps keep labor costs down.
If your roof is aging but still sound, rejuvenating it runs about $2,100 to $2,650, 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.

Share of homes = single-family homes in the ZIP code with an asphalt shingle roof. Maricopa County Assessor, Oct 2026.
Almost certainly not. Asphalt shingles don’t last 50 years in the Arizona sun, so most Mesa homes from that era have been re-roofed at least once, and some twice. Your shingles could be 5 years old or 25. The free assessment tells us which, and whether they’re a good candidate for treatment.
It’s designed to. In independent lab testing on 13-year-old shingles, untreated shingles lost nearly twice as many granules as treated ones. It can’t put back granules that are already gone, so the sooner a drying roof is treated, the more of its protection it keeps. If there are bare patches, we’ll tell you during the assessment.
No. Rejuvenation is made for asphalt shingles only. If your home is one of the shingle roofs on the east side, though, we’re glad to come take a look.
Yes. We serve all of Mesa, from downtown and Dobson Ranch to Red Mountain and Eastmark, plus the rest of the Phoenix Valley. Call or text 480-283-4560 to schedule a free assessment.
