Redwood shade and the moss it feeds
Fairfax sits at the head of Ross Valley, against a watershed (Wikipedia, Fairfax). Tall trees and canyon shade keep roofs wet. Moss builds on shingle edges, lifts tabs and holds water against the roof, and the damage often runs deeper than the surface shows.

We check the shaded slopes first, then the fascia and gutter line. Soft wood at the eaves tells us more than a surface glance. If a slope has years left we say so; if not, we say that too.
Fairfax had 3,470 housing units in the 2020 census, and 35.2% of households rented (Wikipedia, Fairfax). Many roofs here therefore belong to landlords as well as owner-occupants, and a landlord needs a dated photo record and a clear scope more than a sales pitch. The town sits in the valleys of San Anselmo Creek and Fairfax Creek and climbs the hills around them, mostly on Tocaloma soils formed from sandstone and shale, often on slopes steeper than 15 percent. Steep ground adds to ladder placement, staging and debris handling, and we plan for each before the crew arrives.
Narrow streets and small lots
Access can be half the job in a compact canyon town. A ladder, a dumpster and a delivery truck all need room, and we plan where each goes before the day starts.

San Anselmo Creek, Pastori's and the hillside lanes
San Anselmo borders Fairfax to the east and the unincorporated community of Sleepy Hollow lies to the north (Wikipedia, Fairfax). The town's first post office opened in 1910 and it incorporated on March 2, 1931. Pastori's Hotel, once Bird's Nest Glen and later the Marin Town & Country Club, is one of the older landmarks.
To the south lies the Mount Tamalpais watershed, managed by the Marin Municipal Water District. Tall trees, steep lots and creek valleys decide how a roof ages here, and they decide how we plan access. We ask about overhanging limbs and gutter slope before we price a single square.
Wildfire awareness at the watershed edge
The watershed on the south side is a reminder that wildfire is a concern in Marin's wooded towns. We do not guess your fire status: check the CAL FIRE map for your parcel and ask the Town of Fairfax what it requires for a roof assembly.
Zone 2 and the Town of Fairfax
Fairfax is in Climate Zone 2, so a cool-roof product is optional for a single-family reroof. The Town of Fairfax issues permits for homes inside its limits; the estimate names the applicant.
Roof work in Fairfax
- Roof Repair
Shaded wood-sided cottages hold moisture, so repairs start with moss, soft fascia and failed flashing. We check the lowest courses and the wall where roof and siding meet, since water hides there first.
- Roof Replacement
Narrow streets shape staging and debris plans, and Zone 2 leaves product color your choice. With 35.2% of households renting, we also give landlords a written scope they can pass to tenants and managers.
- Gutters
Tall trees overhead fill gutters with needles and leaves through the wet months. On homes tucked into steep hillsides, we make sure downspouts discharge away from the slope instead of undercutting the foundation.
- Emergency Roof Repair
Phone triage and tarp advice first; arrival depends on crew availability and the bridge. If a limb is on the roof, photograph it and keep clear until you hear back from us.
- Roof Inspection
A walk of the shaded slopes, fascia line and gutters, with dated photos, shows how much of the damage is surface moss and how much is soft wood underneath, so you decide with the facts.
- Roof Maintenance
Where redwood shade keeps shingles wet most of the year, scheduled moss removal, gutter clean-outs and a flashing check before the rains can extend the life of a roof that would otherwise age early.
Crossing the bridge from Alameda
Call the Alameda office. A written estimate follows the inspection. We schedule off-peak when we can and call ahead if traffic changes the plan.
