Canyon shade and a roof that stays wet
The valley sits under Mount Tamalpais, and many roofs get little direct sun. Moss grows on shaded shingles, needles sit in valleys, and the first course at the gutter takes the most water. That wear is slower than a storm, but it ends in the same place, a leak.

We look for soft spots at the eave, lifted tabs and flashing that has pulled loose. Often a repair buys time. Sometimes the honest answer is replacement, and we say so in writing with photos.
- Roof Repair
Shade keeps shingles damp, so repair work here starts with moss and soft spots. We probe the eave deck and the first course with a flat bar, then photograph anything that gives.
- Roof Replacement
A reroof on a wildfire-aware parcel can bring material and vent decisions, so we price those first. The estimate lists the covering's fire class and each vent by type.
- Gutters
Canyon trees drop debris into gutters, and clean runs keep water off the fascia. Where gutters sit under heavy canopy, a guard or a deeper profile is worth pricing beside plain cleaning.
- Emergency Roof Repair
Storm leaks get a tarp-first approach, subject to crew availability from Alameda. Tell us where water is entering and whether you can reach the attic, and we will say what is realistic.
- Attic Venting Repair
Vents are a common path for embers into an attic. Old vents can be swapped for fine-mesh, ember-resistant units during a reroof or on their own, and the estimate lists each vent location.
- Roof Maintenance
Moss, needles and wet shade work against these roofs all year. A yearly visit clears valleys and gutters and flags lifted tabs before the first heavy rain.
Fire rules that follow the parcel
Marin's wooded slopes are fire country. California's building code uses Class A roofing and ember-resistant vents in mapped hazard areas, per local reroof handouts for Chapter 7A. Whether your house is covered turns on the parcel and on how much roof is being replaced.
Ask the county before you choose a material. Underlayment and deck condition affect whether a Class A shingle actually earns the rating, so a rotten deck is a code issue as well as a leak issue.

Highway 1, the parks and the edge of the woods
State Route 1 runs through the valley as the main road into western Marin, per Wikipedia. Muir Woods National Monument, Mount Tamalpais State Park, Tennessee Valley and the Golden Gate National Recreation Area lie close by, so many homes back onto wooded land with no buffer. That is why the fire-rated covering and clean vents matter more here than the same shingle on a city street. The valley covers about 4.7 square miles and holds 4,678 homes, so we ask about truck and dumpster parking on the first call.
What a visit involves
The office schedules an inspection from Webster St, often with Wayne or Pedro. You receive a written estimate, plus photos of problem areas. Alameda customers have reported estimates by the next day, though that is an Alameda experience, not a promise for Marin.
Highway 1 runs through the valley, and the bridge approach can add time to any trip. For an urgent leak, call and ask what the crews can do that day.
Nearby, we also cover Strawberry, Mill Valley and Sausalito.
