OUR STORY
Built for the North Bay. Backed by Science.
NorCal Fresh Roof was founded with a simple belief: most Northern California homeowners are replacing roofs years before they need to. With the right treatment — applied by trained technicians, backed by lab data, and protected by warranty — a tired-looking asphalt shingle roof can be brought back to a strong, protected condition.
We work exclusively in the North Bay because we know this climate. The summer UV punishment. The wet-dry winter cycling. The wildfire seasons. Our process is built around what your roof actually faces.
THE SCIENCE
Independent PRI Laboratory Testing
Our GreenSoy™ treatment has been tested by independent third-party laboratories across the most important shingle performance categories.
| Performance Metric | Result | What It Means |
|---|---|---|
| Flexibility Restored | 50% | Asphalt shingles regained half their original flexibility. |
| Stiffness Reduction | 85% | Brittle shingles softened back toward new condition. |
| Flexural Modulus | −61% | Resistance to bending stress significantly improved. |
| Granule Loss in Hail Test | 0% | Treated shingles retained 100% of granules under impact. |
| Fire Spread Reduction | 30% | Independent testing showed reduced flame spread. |
