Your Tulare Roof Isn't Worn Out.
It's Dried Out.
Central Valley sun bakes the oils out of asphalt shingles years early. CenCal Roof Restore replenishes them — restoring flexibility and UV protection across Tulare, Visalia, Hanford and the surrounding Valley — for a fraction of replacement.
Performance figures based on independent PRI laboratory testing. Results depend on shingle condition and eligibility.
5 stars from Central Valley homeowners
"Sergio walked our whole roof, showed us the granule loss, and gave us an honest assessment. Two years in and our shingles still look flexible and dark."
"We were quoted $14k for a full replacement. CenCal treated it in an afternoon and it looks brand new. Wish we'd known this was an option sooner."
"Straightforward, no pressure, and they left the property spotless. Warranty paperwork was in my inbox by the time they packed up."
"Our roof was 14 years old and curling at the edges. Sergio explained the oil-replenishment side of it in plain English and didn't try to sell us a roof we didn't need."
"Booked the free inspection on a Tuesday, treatment was done that Friday. Crew was harnessed, careful around the landscaping, and cleaned up completely."
"We had solar going in and Sergio recommended spraying first so we'd never have to pull panels for a re-roof. Smartest money we spent on the whole project."
Your Roof Isn't Failing — It's Drying Out.
The Central Valley sun is relentless — it bakes the oils out of shingles faster than almost any climate in America. Hundred-degree summers and cold, foggy winters swing your shingles from expansion to contraction until they crack, curl and shed granules.
Most Valley roofs don't need replacing. They need their oils restored — before the damage becomes permanent.
"A roof is like skin — once the natural oils leave, it dries, cracks, and loses its ability to protect what's underneath."
Relentless UV & 100°+ Heat
Long, cloudless summers concentrate UV directly onto asphalt shingles day after day, breaking down the oils that keep them flexible.
Extreme Day-Night Temp Swings
Valley shingles expand in the afternoon and contract at night. That constant cycle micro-cracks the mat until granules start falling off.
Low Humidity + Winter Fog
Dry Valley air pulls moisture and flexibility out of shingles. Dense Tule fog then saturates the brittle surface — a punishing combination.
Six Signs Your Shingles Are Drying Out.
You don't need a ladder to spot most of these. If two or more sound like your home, your roof is likely still a rejuvenation candidate — but that window doesn't stay open forever.
Granules in the gutters
Sandy grit collecting at downspouts means the protective surface layer is shedding — the first measurable sign the shingle's oils have baked out.
Faded, chalky color
A roof that used to be charcoal and now looks washed-out grey is losing the asphalt binder that gives shingles both color and waterproofing.
Curling or cupping edges
Once shingles dry out they shrink and lift at the corners. Caught early, rejuvenation restores flexibility; left alone, the mat cracks for good.
Roof age 8–20 years
This is the rejuvenation window. Valley heat ages shingles roughly 30–40% faster than the national average, so a 10-year Tulare roof often behaves like a 15-year roof.
Brittle to the touch
A healthy shingle flexes. A dried-out one snaps. We test flexibility by hand during every free inspection so you can see it yourself.
Insurance or solar deadline
Carriers asking questions about roof age, or an installer about to cover your slopes with panels — both are reasons to treat now rather than later.
Boots on the roof, harness on, spray wand in hand — Sergio and his crew treat every home themselves.
GreenSoy™ Rejuvenation — Not a Coating. A Restoration.
Roof coatings sit on top of shingles and eventually peel. GreenSoy™ does the opposite — it penetrates the shingle mat and replaces the natural oils that heat and UV pulled out. The result is a shingle that behaves like new: flexible, adhesive and UV-protected from the inside.
Restores Lost Oils
Replenishes the maltenes that keep asphalt shingles flexible and waterproof.
Renews UV & Weather Protection
Restores the shingle's ability to shed water and reflect UV — inside out, not surface coating.
Improves Fire & Hail Resilience
Lab testing shows 0% granule loss in impact tests after treatment.
Bio-Based & USDA Certified
Soy-derived formula — safe for landscaping, pets and Valley waterways.
Eligibility matters. Rejuvenation is for shingle roofs that still have life left in them. If your roof doesn't qualify, we'll tell you honestly — no upsell.

GreenSoy™, Explained Without the Sales Pitch.
An asphalt shingle is a fiberglass mat saturated in asphalt and topped with ceramic granules. The asphalt is held together by light oils called maltenes. Those oils — not the granules, not the mat — are what Valley sun destroys first. GreenSoy™ is a bio-based, USDA certified soy oil engineered to put them back.
Penetration
GreenSoy™ is sprayed at a controlled rate and wicks down into the asphalt matrix rather than sitting on top of it. This is why it isn't a coating — coatings peel, rejuvenators absorb.
Oil Replenishment
The soy-derived maltenes bond with the aged asphalt binder, replacing the light oils that UV and 100°+ heat drove out of the shingle over the years.
Restored Performance
As the binder re-softens, the shingle regains flexibility, grips its granules again, and reclaims its ability to shed water and reflect UV — measured in lab testing, not estimated.
| Approach | How it works |
|---|---|
| Rejuvenation | Absorbs into the shingle and restores the binder from within. No added weight, no film to peel. |
| Roof coating | Sits on the surface as a film. Hides the symptom, adds weight, and can trap moisture as it ages. |
| Full replacement | Tears the roof off entirely. The right answer for failed roofs — overkill for one that's simply dried out. |
Performance claims reflect independent PRI laboratory testing of the GreenSoy™ formula. Results on any individual roof depend on shingle condition and eligibility.
Rejuvenate Your Roof Before the Panels Go On.
Solar systems last 25–30 years. Your shingles need to last just as long — and removing panels later to replace a tired roof costs thousands. Spraying GreenSoy™ before installation extends shingle life so your roof and your solar array age together.
- Adds years of shingle life under the array
- Avoids costly panel removal for future re-roofs
- Ideal for homes 8–20 years into their roof
- Documented maintenance record for your installer
Backed by a 6-Year Transferable Warranty.
Every completed treatment includes a written 6-year warranty. If you sell your home, the warranty transfers to the next owner — documented, verifiable proof of proactive roof maintenance that adds value to your home.
Proof That Your Roof Is Being Maintained.
California insurers are increasingly scrutinizing roof age and condition. Homeowners across the Valley are being non-renewed or seeing premiums jump on roofs that still have years left. A completion report and before-and-after photo package from CenCal give you documented evidence of proactive maintenance — the kind of paperwork insurers actually want to see.
Insurance policies vary — always confirm specifics directly with your carrier.
