Why the hills are different
The 1991 Oakland hills fire made roof fire ratings a local priority. Today, the state's fire hazard severity zone map (revised 2025) and Berkeley's Chapter 19.49 shape what goes on a hill home's roof.
What qualifies as Class A?
Per the Department of Insurance, asphalt shingles, concrete, brick or masonry tiles, and metal shingles or sheets usually qualify; wood shakes don't (Safer from Wildfires).
Beyond the roof covering
| Detail | Why it matters in the hills |
|---|---|
| Vents | Ember-resistant vents keep embers out of the attic |
| Gutters | Leaf-filled gutters catch embers along the roof edge |
| Roof-to-wall joints | Gaps let embers lodge against siding |
| Skylights | Check fire ratings when reroofing |
The state fire marshal's building in the wildland page explains the wider WUI rules.
Insurance
A Class A roof is one of the Safer from Wildfires steps insurers recognize with discounts. In the hills, it can also be the first thing an underwriter asks about.
Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.
