What should I ask a Berkeley roofing company before replacing my roof?

What's under a Berkeley roof?

Often more than you'd expect. Berkeley's median home was built in 1944, the oldest of any East Bay city we track (ACS 2024 5-year). Brown-shingle and Craftsman houses in North Berkeley, Elmwood and South Berkeley can have two or three coverings, sometimes over original wood shingles, on spaced boards rather than plywood. Ask how the roofer prices solid sheathing over spaced boards, and get a unit price in writing so the change order isn't a surprise.

How do I vet a roofer for my Berkeley home?

Start with the state record: the CSLB lookup shows whether the license is active, whether it includes C-39 roofing (classification), and any public complaints or disciplinary actions. CSLB's hiring checklist adds the basics: written bids, no cash-only deals, and no large payment before work starts.

Does Berkeley's fire code apply to my roof?

If you're in one of the city's fire zones, likely yes. Berkeley adopted a Wildland-Urban Interface code chapter in 2025 (Berkeley WUI ordinance), which sets requirements for roofing and other exterior parts in those zones. Check your address with the city and on CAL FIRE's map, and ask bidders to confirm the full assembly meets it. Our ember-resistant vents guide covers the details around the roof.

Questions for every Berkeley bidder

1. How many layers will you remove, and what's the sheathing unit price?
2. Will you rebuild chimney flashing, or reuse it?
3. Is your proposed roof Class A as an assembly, and does it meet the WUI chapter if it applies?
4. Who pulls the permit through the city's online permit system?
5. How will you protect old wood siding and gardens during tear-off?

What about cost?

We keep prices on a separate page: what drives a new roof's price in Berkeley. The short version is that roof size, pitch, material, tear-off layers, decking and access decide it, so the free written estimate is where your actual number comes from.

Which local conditions should a Berkeley reroof plan for?

At the Berkeley station, the 1991-2020 normals show 26.1 inches a year, with 58% in the three winter months and roughly 6 days at 90 degrees or more (NOAA). Parts of Berkeley are rated Very High on CAL FIRE's 2025 recommended map; inside those areas, Class A is mandatory once more than half the roof is replaced (HSC 13132.7). The Hayward fault runs through Berkeley (USGS), so a switch to heavy tile deserves a structural check. Look up your own parcel on CAL FIRE's map.
