When does a North Bay roof need replacing?

Short answerNorth Bay warning signs depend on where you live: cracked, bald shingles on sunny Santa Rosa and Napa slopes, moss lifting shingles under west-county redwoods, split or cupped wood shakes on older homes, and attic stains after the first storms. When the wear is roof-wide, plan a replacement.

Checklist by roof type

Composition shingles: granules in gutters, curling, cracks, bare spots.

Wood shake: splitting, cupping, missing shakes, moss mats. Shake isn't Class A, which matters for insurance.

Tile and metal: slipped tiles, rusted fasteners, loose panel seams.

Local patterns

North Bay roofers commonly see moss and debris damage under trees in Mill Valley, Fairfax and the west county, sun-cracked shingles on south-facing inland slopes, and older wood shake roofs that raise fire-rating questions before anyone replaces them in kind.

Fire season check

Before summer, look for debris in gutters and valleys and gaps at vents. Embers find those first.

Time to call

When a stain grows after each storm, when an insurer flags the roof, or before you list the house.

Frequently asked questions

Is my shake roof a problem for insurance?

Wood shake isn't Class A, so it won't count toward Safer from Wildfires discounts and may draw underwriting questions.

Moss on my Sebastopol roof: replace?

Not automatically. If shingles are lifted or brittle across the roof, replacement is often the better fix.

What should I check before fire season?

Gutters, valleys and vents for leaves and needles.
