4.9/5 — Trusted by North Bay homeowners
"We had quotes for $18,000 to replace the roof. After the inspection they showed us why rejuvenation was the right call first. Saved us a fortune."
"Done in a few hours. Roof looks completely different. Couldn't believe how quick and clean the whole thing was."
"They walked us through everything — the science, why it works, what to expect. Very trustworthy company."
THE REAL PROBLEM
Your Roof Isn't Failing — It's Drying Out.
Asphalt shingles don't fail from age. They fail from oil depletion.
Every shingle is manufactured with natural oils that keep it flexible, adhesive, and UV-resistant. In Northern California, long dry summers with intense direct UV — combined with wet Pacific winters — create a cycle that strips those oils faster than most climates. Once gone, shingles become brittle, lose granules, crack, and curl.
Traditional roofing diagnoses this as "end of life" and recommends a $14,000–$22,000+ replacement. But the shingle structure is often still sound. Only the oils are missing.
Relentless NorCal UV
Months of cloudless California summers strip shingle oils season after season.
Wet-Dry Cycling
The North Bay's dry summers and wet winters accelerate oil evaporation and surface cracking.
Wildfire Particulates
Ash and smoke residue from NorCal wildfire seasons accelerate surface degradation.
THE SOLUTION
GreenSoy™ Rejuvenation — Not a Coating. A Restoration.
NorCal Fresh Roof uses GreenSoy™ technology — a bio-based, soy-derived treatment that penetrates deep into asphalt shingles, chemically replenishing the oils that UV and weather have stripped away.
It doesn't sit on the surface. It revives from within.
Restores Lost Oils
Soy-derived polymers bond with asphalt, restoring flexibility and adhesion.
Re-Seals Granules
Reactivates the tar layer, locking protective granules back in place.
Improves Fire Resistance
Independent testing shows 30% reduction in flame spread.
USDA Certified Bio-Based
Plant-based, zero-waste alternative to full tear-off.
Eligibility note: Not all roofs qualify for rejuvenation. Our free inspection evaluates your shingle condition, age, and existing damage before any recommendation is made.
