We’ve been climbing Kentfield roofs since 1984. Our crews know the difference between a ranch on a Kent Woodlands hillside and a craftsman near College Avenue, and we know how the valley’s funnel geography channels rain and fog straight into these neighborhoods. That local knowledge changes what materials we recommend and how we detail the flashing. When you’re replacing a roof in one of the rainiest spots in the Bay Area, you want a crew that understands why standard specs often fall short here.

Our Roof Replacement & Installation Services in Kentfield
Full Roof Replacement
Most Kentfield homes we see are due for replacement. Mid-century ranches and split-levels built in the 1950s-1970s carry original roofs that have endured 50-60+ inches of annual rainfall year after year. The redwood and oak canopy that makes Kentfield beautiful also deposits organic debris that traps moisture against shingles or shakes, accelerating decay. We remove to decking, assess for rot (common in Kent Woodlands homes where duff has sat for decades), and install systems designed for this microclimate - algae-resistant underlayments, stainless fasteners, and proper ventilation to combat the near-constant humidity.
New Construction Roofing
New builds in Kentfield, whether in the hillside neighborhoods or closer to the Kentfield Post Office on College Avenue, must meet Marin County’s evolving fire-resistant roofing requirements for the wildland-urban interface. We install Class A rated systems from the start, with proper ridge venting specified for the cooler, foggier summers that limit drying cycles. Our Roof Replacement & Installation team works directly with local builders and homeowners to specify materials that satisfy code and perform for decades in this rainfall environment.
Asphalt Shingle Roofing
Asphalt shingles are the workhorse for Kentfield’s ranch and split-level housing stock. We install GAF Timberline HDZ and CertainTeed Landmark lines with StainGuard algae resistance - critical here, where the orographic lift off Mount Tamalpais sustains humidity that feeds moss and black streaks on standard shingles. Granule loss accelerates under Kentfield’s tree canopy; we specify heavier-weight laminates and install them with full synthetic underlayment, not felt, because this much annual rainfall will find any shortcut. A typical 2,500-square-foot asphalt replacement in Kentfield runs $18,000-$28,000.
Metal Roofing
Metal roofing handles Kentfield’s rainfall with minimal maintenance and sheds debris better than shingle or tile. Standing seam systems in aluminum or galvanized steel resist the moss colonization that plagues other materials here, and they perform well on low-slope sections where standing water from winter rains destroys conventional membranes. We install Atlas and Tamko metal product lines with proper underlayment and thermal breaks for the cooler summer temperatures. Expect $35,000-$55,000 for a typical Kentfield home. The payoff is 40-70 years of service with biennial debris clearing rather than constant moss treatment.
Flat Roofing
Flat and low-slope sections on Kentfield hillside homes are failure points. The heavy winter rains pool on inadequate drainage, and the valley’s sustained humidity prevents proper drying. We install TPO and modified bitumen systems with tapered insulation to move water, and we always recommend integrating these sections into a broader roof maintenance plan. Without it, we’ve seen three-year membrane failures in Kent Woodlands - not from defective material, from water that had nowhere to go.
Tile Roofing
Clay and concrete tile suits the colonial-revival homes near College Avenue and some custom builds in the hills. The weight requires structural verification, especially on older homes not originally designed for tile. We install Boral and Eagle Roofing products with proper battens and underlayment rated for prolonged moisture exposure. In Kentfield’s climate, the underlayment is the critical layer - it does the waterproofing for the life of the roof, while the tile provides protection and aesthetic.

Common Roof Replacement & Installation Problems We See in Kentfield Homes
- Moss and lichen colonization destroys asphalt shingles from the top down. Kentfield’s orographic microclimate sustains growth rates double or triple the regional average. Granules wash away, exposing mat, and moisture penetrates. We see this pattern repeat on shaded slopes throughout Kent Woodlands and the hillside neighborhoods above Sir Francis Drake Boulevard.
- Organic debris traps moisture against wood shake and asphalt surfaces year-round. Redwood needles, oak leaves, and bay laurel duff form a sponge that never fully dries in this humidity. Wood shakes saturate and rot through. Asphalt shingles delaminate. Without biennial clearing and moss treatment, a new roof in Kentfield faces premature failure in three to four years.
- Standing water on low-slope sections accelerates membrane and decking deterioration. The 50-60+ inches of annual rainfall finds every inadequate pitch. We’ve replaced decking on hillside homes where the low-slope garage roof was originally framed with minimal fall, and decades of ponding had rotted the structure below.
- Original wood shake roofs are past service life and increasingly non-compliant with fire codes. Many Kentfield homes built in the 1950s-1970s still carry these shakes. They’re a ignition risk in the wildland-urban interface, and most insurers now require replacement with Class A rated materials. We handle the permit process with Marin County and ensure compliance.
Pricing for Roof Replacement & Installation in Kentfield, CA
Roof replacement costs in Kentfield reflect the complexity of hillside access, the need for moisture-specific materials, and Marin County permit requirements. Here are typical ranges we quote for Roof Replacement & Installation in Kentfield:

| Decking replacement (per sq ft) | $4 - $8 | Common in Kent Woodlands homes with decades of moisture damage |

FAQs - Roof Replacement & Installation in Kentfield
Kentfield receives 50-60+ inches of annual rainfall versus 25-30 inches in San Rafael, and the orographic lift at the base of Mount Tamalpais creates sustained humidity that feeds moss, algae, and lichen at rates double or triple the regional average. The surrounding redwood and oak canopy deposits organic debris that traps moisture against roof surfaces year-round. For a roof inspection that accounts for these local conditions, call (877) 367-1429 - estimates are free.
Yes. Marin County enforces fire-resistant roofing requirements in the wildland-urban interface, which includes most of Kentfield and especially the Kent Woodlands hillside areas. Original wood shake roofs are increasingly non-compliant, and many insurers now mandate Class A rated replacement materials. We handle permit compliance and install GAF, CertainTeed, and Atlas Class A systems. Call us to verify your current roof’s rating and discuss replacement options.
Twice yearly, minimum - late fall after leaf drop and early spring before the heavy rain season. In Kent Woodlands specifically, the combination of coast redwoods and California bay laurels produces duff that holds moisture against shingles or shakes continuously. Without biennial clearing and moss treatment, we’ve seen new roofs require callbacks within three to four years. We offer an $89 Seasonal Tune-Up that includes debris removal, Gutters & Accessories - Kentfield clearing, and moss inspection.
Yes. Metal roofing sheds water and debris more effectively than shingle or tile, and its smooth surface resists the moss colonization that plagues other materials in Kentfield’s humidity. Standing seam systems perform particularly well on low-slope sections where standing water destroys conventional membranes. We install Atlas and Tamko metal lines with proper underlayment for the cooler, foggier summers. Typical cost is $35,000-$55,000 for a Kentfield home. Call for a specific quote.
We specify synthetic underlayment with algae-resistant properties, never organic felt, for all Kentfield installations. On asphalt shingle jobs, we use GAF FeltBuster or CertainTeed DiamondDeck with enhanced moisture resistance. For tile and metal, we install premium self-adhering membranes at valleys, eaves, and penetrations - the failure points where Kentfield’s 50-60+ inches of annual rainfall concentrates. The underlayment is your last line of defense; in this climate, we don’t cut corners. Call (877) 367-1429 to discuss specifications for your roof.
