Roof rejuvenation in Sun City
Three in four Sun City homes have asphalt shingle roofs, about 13,600 in all, and every one of them is single-story. 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.
Three in four Sun City homes have shingles
No community in the Valley has a higher share of shingle roofs. Nearly all of them are on homes built in the 1960s and 1970s, and all of them are on single-story homes.

Sun City went up in the ’60s and ’70s
Sun City opened in 1960 as one of the country’s first planned retirement communities and was built out over the next twenty years. Of today’s shingle-roof homes, 36% date from the 1960s and 64% from the 1970s. In ZIP code 85351, 86% of single-family homes have shingles.
After 45 to 65 Arizona summers, these homes have all been re-roofed at least once, so the shingles may be much younger than the house. A free assessment checks the shingles you have now: how flexible they are, how well the granules are holding, and whether the roof is still sound.

What Sun City 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 Sun City home before we visit.
Usually a good fit
- An asphalt shingle roof on a single-family home, the most common kind in Sun City
- 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 (about 1 in 10 Sun City 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 Sun City
A typical Sun City shingle-roof home has about 2,100 sq ft of roof, so replacing it runs roughly $8,500 to $14,500 in 2026.
Every shingle-roof home in Sun City is single-story, and the typical one has about 1,500 sq ft of living space plus a garage or carport. Low, 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.

Where Sun City’s shingle roofs are
Sun City’s two ZIP codes and how many single-family homes in each have an asphalt shingle roof.
| ZIP code | Homes with shingle roofs | Share of homes |
|---|---|---|
| 85351 | 10,800 | 86% |
| 85373 | 2,900 | 51% |
Share of homes = single-family homes in the ZIP code with an asphalt shingle roof. Maricopa County Assessor, Oct 2026.
Yes. We serve all of Sun City, in 85351 and 85373, along with Sun City West, Youngtown and the rest of the West Valley, plus the rest of the Phoenix Valley. Call or text 480-283-4560 to schedule a free assessment.
Probably not, because the roof is much younger than the house. Shingles don’t last 50 years, so every Sun City home has been re-roofed at least once. What matters is the shingles on it today, and our free assessment checks their flexibility, granule coverage and overall soundness before we recommend anything.
No. The work happens on the roof, so you don’t need to be inside. We’ll set the timing with you and arrange access to the yard, whether that’s with you, a neighbor or someone who looks after the house while you’re gone.
If your roof qualifies, a treatment runs about $2,100 to $2,650 for a typical Sun City home, a fraction of a new roof, and puts off the cost and disruption of a tear-off. Every treatment comes with our 5-year warranty, with terms given to you in writing before work begins. If your roof is too far gone for treatment to help, we’ll tell you that instead.
