Roof rejuvenation in Gilbert
Gilbert is a tile town: 94% of its single-family homes have tile roofs. About 3,900 have asphalt shingles, and two-thirds of those are in north Gilbert, in ZIP codes 85233 and 85234. 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.

A tile town with a few thousand shingle roofs
Nine in ten Gilbert homes were built in 1990 or later, almost all with tile. The shingle roofs are on the town’s earlier homes, mostly in north Gilbert.

Gilbert’s shingle roofs came before the boom
Most of Gilbert was built after 1990, and those neighborhoods are almost all tile. Its shingle roofs are on the earlier homes: three in four were built in the 1970s and 1980s, mostly in north Gilbert near the Mesa border.
Homes that age have usually been re-roofed at least once, so the shingles may be much younger than the house. A free assessment checks the shingles themselves for flexibility, granule coverage and soundness.

What Gilbert 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 Gilbert home before we visit.
Usually a good fit
- An asphalt shingle roof on a single-family home, most common in north Gilbert
- 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 Gilbert homes), 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 Gilbert
A typical Gilbert shingle-roof home has about 2,200 sq ft of roof, so replacing it runs roughly $9,000 to $15,500 in 2026.
Gilbert’s shingle-roof homes vary more in size than most. The median is about 1,650 sq ft of living space, but one in seven has 2,500 sq ft or more, the highest share of the cities we cover. On a larger home, the cost of a new roof can climb well past the typical range.
If your roof is aging but still sound, rejuvenating it runs about $2,200 to $2,750, tune-up included, and can put that bill off.

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 the way a replacement or coating would. It doesn’t change your roof’s materials, style or color scheme, though faded shingles often look richer and less weathered afterward. If your HOA asks about roof work, we’re happy to provide product details.
Not necessarily. Most homes from that era have been re-roofed, so the shingles may be much younger than the house. What matters is their condition today, and our free assessment checks flexibility, granule coverage and soundness before we recommend anything.
No. Rejuvenation is made for asphalt shingles only. If your home is one of Gilbert’s shingle roofs, we’re glad to come take a look.
Yes. We serve all of Gilbert, from the Heritage District and Val Vista Lakes to Power Ranch and Seville, plus the rest of the Phoenix Valley. Call or text 480-283-4560 to schedule a free assessment.
