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.

"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."
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.
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.

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.
