Roof rejuvenation in Scottsdale
Scottsdale is known for tile roofs, but about 20,700 of its homes have asphalt shingles, most of them in the established neighborhoods of south and central Scottsdale. ShingleGuard’s bio-based treatment is designed to replace the oils those shingles lose to the desert sun, so a qualifying roof can keep doing its job instead of being torn off early.
One city, two kinds of roofs
North Scottsdale is almost all tile. The shingle roofs are on homes to the south and in the middle of the city, and nearly all of them have been through decades of Arizona summers.

Built in the ’50s and ’60s, re-roofed since
More than half of Scottsdale’s shingle-roof homes went up in the 1950s and 1960s, as the young city spread out from Old Town into the ranch-home neighborhoods of south Scottsdale. Most of the rest came in the 1970s and 1980s, including the shingle homes of McCormick Ranch. Almost all of them (96%) are single-story.
Asphalt shingles don’t last 60 years, so most of these homes are on their second or third roof, and plenty of mid-century Scottsdale homes have been remodeled and re-roofed more recently than that. That’s why the year on the deed doesn’t tell us much. A free assessment looks at the shingles you have now: how flexible they are, how well the granules are holding, and whether the roof is still sound.

What Scottsdale does to asphalt shingles
Every asphalt roof ages. Here, it happens faster.
Long Valley summers
Scottsdale shares the Phoenix area’s summers, with more than 100 days at 100°F or hotter in a typical year. Heat drives the oils out of asphalt shingles, and the longer the summer, the faster they dry out and stiffen.
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 Scottsdale home before we visit.
Usually a good fit
- An asphalt shingle roof on a single-family home, common in south and central Scottsdale
- 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 north Scottsdale), 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 Scottsdale
A typical Scottsdale shingle-roof home has about 2,400 sq ft of roof, so replacing it runs roughly $9,500 to $17,000 in 2026.
Scottsdale’s shingle-roof homes are the biggest of the Valley cities we cover: a median of about 1,800 sq ft of living space, and one in eight has 2,500 sq ft or more. More house means more roof, so a typical replacement here runs about $1,500 to $3,000 more than in Phoenix.
If your roof is aging but still sound, rejuvenating it runs about $2,400 to $3,000, 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.

No. Rejuvenation is made for asphalt shingles only. Tile roofs age differently: the tiles themselves last a long time, and it’s the underlayment beneath them that wears out, which a surface treatment can’t reach. If your home is one of the few shingle roofs up north, we’re glad to come take a look.
Probably not, because the roof is almost certainly younger than the house. Shingles don’t last 70 years, so a home that age has been re-roofed at least once and often twice. What decides it is the shingles on it today. Our free assessment checks their flexibility, granule coverage and overall soundness, and if the roof is past the point where treatment makes sense, we’ll tell you.
More than half of Scottsdale’s shingle-roof homes have a pool, so we hear this a lot. The treatment is water-based and designed for safe use around homes, and in independent testing, rain runoff from treated shingles showed no detectable PAHs or PCBs. We’ll walk the property with you before we start, and we ask that people and pets stay clear until the roof 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.
Many Scottsdale neighborhoods, including McCormick Ranch, have HOAs with design guidelines for roofs. Rejuvenation doesn’t change your roof’s materials, style or color scheme the way a replacement or coating might, but some associations still like to be told about roof work. Check your guidelines, and if your HOA asks, we’re happy to provide product details.
Yes. We serve the whole city, from Old Town and south Scottsdale to McCormick Ranch, the Shea Corridor and north Scottsdale, plus the rest of the Phoenix Valley. Call or text 480-283-4560 to schedule a free assessment.
