Repair or replace a roof in wine country and Marin?

Short answerIn the North Bay, replace when the roof is wood shake you'd have to swap for Class A anyway, when inland Sonoma or Napa sun has left shingles cracked and bald, or when the roof already has two layers. Repair when damage is limited to a storm-hit patch, a valley or flashing on an otherwise sound roof.

Wood shake roofs

Wood shake shingles aren't Class A (Safer from Wildfires). In unincorporated Sonoma County, re-roofing more than half the roof requires a Class A assembly (B-07). Small repairs to a shake roof buy time, but a full replacement will change the material.

Inland vs. coastal wear

Area Typical failure Lean toward
Santa Rosa, Napa, Sonoma Valley Heat-cracked, bald shingles Replace if widespread
West county, Russian River Moss, debris, damp decks Clean and repair if young; replace if lifted
Marin hills Tree litter, wind at ridges Repair isolated damage

When the code decides

No new layer over two existing layers, over water-soaked roofing, or over tile or slate (CRC R908).

Age as a guide

InterNACHI lists architectural shingles at about 30 years and wood shake at about 25 (InterNACHI).

Frequently asked questions

Can I patch my shake roof instead of replacing it?

For small areas, yes. A full or majority replacement in unincorporated Sonoma County must be a Class A assembly.

My Santa Rosa roof is 25 years old. Replace?

Have it inspected. Inland heat often wears shingles out near that age.

Does a repair need a permit?

Small repairs often don't; reroofs do. Ask your building department.
