Why Birchbark Roofing Is Half Moon Bay’s Preferred Roof Replacement Company

Half Moon Bay homeowners keep telling us the same thing: they don’t want surprises. They want a crew that shows up when promised, keeps the yard clean enough that the kids and dog can still use it after we’re gone, and puts the price on paper before a single shingle comes off. That’s how we run every job. Shoe covers go on at the door. Drop cloths run through the hallway to whatever room we need access to. And before the crew pulls out of the driveway, you get a photo of the completed clean-up. Erik Lindgren set that standard, and every tech on a Birchbark roof in Half Moon Bay follows it.

We’re part of the Cedarwell family of roofing companies, which has been holding independent local crews to the same Care Promise since 2000. For Half Moon Bay families, that means background-checked, uniformed technicians who introduce themselves by name. It means a live person answers when you call, day or night, even on weekends. And it means the 365-Day Done Right Promise sits behind every roof we replace – if something isn’t right, we make it right. We also carry a Roof Replacement line of work that covers full tear-offs, new construction, asphalt and architectural shingles, decking replacement, and flat roofing. Whatever your home needs, it starts with a written price, not a handshake.

Roof Replacement Contractor in Half Moon Bay

A Roof Replacement Contractor in Half Moon Bay does more than swap shingles – the job means knowing what this marine climate does to a roof over 20 years and specifying materials that hold up to it. A full replacement here typically involves a complete tear-off down to the decking, inspection and replacement of any rotted or water-damaged sheathing, new underlayment rated for high moisture exposure, new flashing, and new shingles installed to meet wind-uplift requirements for exposed coastal planes. For an average Half Moon Bay home, you’re looking at $18,000 to $45,000 depending on roof size, pitch, and how much decking needs replacing. The written price you get from us includes every line item – no change orders later.

Decking and underlayment upgrades

Older homes in Half Moon Bay’s historic district often hide water damage under three layers of old roofing. We inspect every inch of decking once the old roof comes off and replace what’s compromised. On coastal jobs we upgrade to a synthetic underlayment or double-layer felt in high-exposure areas, because the fog drip here will find any weakness.

Marine-grade hardware throughout

We standardize on stainless-steel flashing and hot-dipped galvanized ring-shank fasteners for any Half Moon Bay roof within reach of salt air. Standard galvanized hardware fails in 5 to 8 years here. Stainless is spec’d to last decades. It’s a small line item that separates a roof that lasts from one that leaks early.

Asphalt Shingle Roof Replacement in Half Moon Bay

Asphalt Shingle Roof Replacement in Half Moon Bay is the most common project we take on, and the material choice matters more here than it does inland. Architectural asphalt shingles from CertainTeed or GAF dominate this market because they carry higher wind ratings – typically 110 to 130 mph – which matters on northwest-facing planes near Pillar Point where winter gusts hit hard. A typical asphalt shingle replacement runs $14,000 to $32,000 in Half Moon Bay, depending on roof complexity and whether you’re in the flatlands or up on an exposed ridge. You’ll see your exact number in writing before we start.

Salt air and shingle longevity

The same fog that feeds Half Moon Bay’s pumpkins also feeds moss and algae on roof planes that stay shaded and damp. We recommend algae-resistant shingles for most coastal homes here, and we’ll talk through which profiles have actually performed well in this specific microclimate. CertainTeed’s Landmark line and GAF’s Timberline series both hold up better than budget three-tab options.

Fasteners and flashing choices

An asphalt shingle roof is only as good as what holds it down. On every Half Moon Bay job we use ring-shank stainless fasteners and stainless drip edge instead of standard galvanized. The prior roof on a Victorian we replaced near Main Street had corroded galvanized flashing failing within five years; our stainless specs push that timeline out decades, even this close to the water.

Trusted Brands We Service in Half Moon Bay

We work with a focused set of manufacturers because Half Moon Bay’s damp, saline conditions punish cheap materials. On most local replacements we install GAF, CertainTeed, and Atlas architectural shingles, plus Boral products when a homeowner wants a synthetic shake look that suits the historic districts. For flat and low-slope sections on older coastal homes, we lean on Tamko and GAF low-slope systems. Because we order directly through established supplier relationships, we can get Half Moon Bay customers the specific product they want with shorter lead times than a generalist roofer who orders one-off. If you’re deciding between two shingle grades, call us and we’ll show you what each one looks like on a house three blocks from yours – because we’ve probably roofed it.

Common Roof Replacement Problems We See in Half Moon Bay Homes

• Corroded flashing and fasteners: Salt-laden air eats standard galvanized hardware. We routinely see flashing that’s lost its bond in under a decade, which is why we spec stainless on every coastal job.
• Moss and algae lifting shingle edges: Chronic fog drip keeps north-facing and shaded roof planes damp for most of the year. Moss colonies push under shingle edges and trap moisture against the decking, accelerating rot.
• Ponding on low-slope historic roofs: Victorian and Craftsman homes near Main Street often have roof sections with drainage pitch that wasn’t designed for modern underlayment. Ponding water finds its way through, especially during concentrated winter storms.
• Multiple layers of old roofing hiding damage: Decades of patch jobs on older Half Moon Bay homes mean we often find two or three layers of composition shingles over rotted decking. A full tear-off is the only way to see what’s actually happening underneath.
