Roof rejuvenation in Phoenix
More than half of Phoenix’s single-family homes have asphalt shingle roofs, and the desert sun is hard on every one of them. ShingleGuard’s bio-based treatment is designed to replace the oils your shingles lose, so a qualifying roof can keep doing its job instead of being torn off early.
Phoenix is a shingle-roof city
Most of these roofs sit on homes that have been through decades of Arizona summers. County records show how many homes could benefit from keeping their shingles flexible longer.

Your house’s age isn’t your roof’s age
Most of Phoenix’s shingle-roof homes went up between the 1950s and the 1980s, from the ranch homes of North Central Phoenix and Maryvale to the subdivisions of North Phoenix and Paradise Valley Village. Nearly all of them are single-story.
Asphalt shingles don’t last 60 or 70 years, so most of these homes have been re-roofed at least once, and the shingles on them may be anywhere from a few years to a few decades old. That’s why we never judge a roof by the year the house was built. A free assessment looks at the shingles themselves: how flexible they are, how well the granules are holding, and whether the roof is still sound.

What Phoenix does to asphalt shingles
Every asphalt roof ages. Here, it happens faster.
More than 100 days a year at 100°F or hotter
Heat drives the oils out of asphalt shingles. The longer and hotter the summer, the faster shingles dry out, stiffen and start to shed granules.
Warm nights in the city
Pavement and buildings hold heat, so central Phoenix often stays warm well into the night. Roofs get less time to cool off between hot days.
Monsoon season, June 15 to September 30
Sudden wind, dust and heavy rain test every shingle on the roof. Dry, brittle shingles are more likely to crack, lift or lose granules when storms roll through.
Rejuvenation fits some roofs, not all
We’ll tell you honestly after a free assessment. Here’s a quick way to gauge your Phoenix home before we visit.
Usually a good fit
- An asphalt shingle roof on a single-family home
- Shingles that look faded, dry or chalky, or granules collecting at the 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, metal, foam or flat roofs (common on many Phoenix homes)
- Active leaks, soft decking or water stains on the ceiling
- Many missing, torn or badly curled shingles
What a new roof costs in Phoenix
A typical Phoenix shingle-roof home has about 2,000 sq ft of roof, so replacing it runs roughly $8,000 to $14,000 in 2026.
Phoenix homes run small. The typical shingle-roof home has about 1,500 sq ft of living space, and one in three parks under a carport rather than in a garage, so roofs here are often a little smaller than the Valley norm. The catch is age: many central Phoenix homes date to the 1950s or earlier, and older homes sometimes have a second layer of shingles to tear off or decking to repair once the old roof comes off. Both add to the bill.
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.

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 necessarily. Asphalt shingles don’t last 70 years, so a home that age has been re-roofed at least once, and the shingles on it now may be much younger than the house. What matters is the condition of the shingles today. Our free assessment checks their flexibility, granule coverage and overall soundness before we recommend anything.
Many older Phoenix homes combine a pitched shingle roof with a flat or low-slope section over an addition, porch or carport. Rejuvenation is only for the asphalt shingle part of the roof. Flat, foam and built-up sections need different maintenance, and we’ll point out anything we notice on them during the assessment.
The treatment needs a dry roof and dry weather, which Phoenix has most of the year. During monsoon season, June 15 to September 30, we watch the forecast closely and reschedule if storms are expected. Many homeowners like to treat in fall, winter or spring, before the next summer of heat and storms. In warm, dry weather the treatment 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.
$1.00 to $1.25 per square foot of roof, about $2,000 to $2,500 for a typical Phoenix shingle home, with a roof tune-up included. A new roof for the same home runs about $8,000 to $14,000. You get the exact price in writing after your free assessment, before you decide anything. Every treatment comes with our 5-year warranty, with terms given to you in writing before work begins.
