Fast, Reliable Roofing Across Half Moon Bay
A new roof or a roof repair in Half Moon Bay runs $400 to $40,000 depending on the job, and the single biggest variable here isn’t shingle choice, it’s whether your project triggers a California Coastal Commission permit review. Most of Half Moon Bay sits inside the coastal zone, which means reroofing that would be a one-day over-the-counter permit in Burlingame or Millbrae can add months of review time here. We know that, we plan for it, and we write every scope and every allowance on paper before we lift a shingle. Call (877) 610-1318 for a free estimate, and you’ll talk to a live person who knows Half Moon Bay’s permit path cold.
Why Barrett & Sons Construction Is Half Moon Bay’s Preferred Roofing Company
We’ve been at this since 1998, and Tom Barrett has been the name on the truck since day one. When you call about a roof in Half Moon Bay, you reach a live person, not a voicemail box, and the crew that shows up carries Barrett & Sons on their uniforms and their work. Our Roofing team answers for every job with a written change order before any scope shift touches your project. That matters on older Half Moon Bay homes, where the eaves can hide rot no inspector saw coming.
Half Moon Bay customers ask us about reviews, and we tell them the same thing we’ll tell you: Tom Barrett publishes his name, his address, and his license number, and you can look all of it up before you sign anything.
Every eligible job gets permits pulled and inspections signed, because the permit inspector works for you, not for me, and that’s why I like him. Ask anyone on your street, or check the license number yourself.
When a Half Moon Bay homeowner calls about a leak, we show up quickly, because the marine layer doesn’t wait and neither does a wet ceiling. We’re a San Francisco Bay Area company with local crews serving Half Moon Bay and the coastside, and we carry the standing seam metal, tile, and underlayment materials that half of San Mateo County doesn’t stock on the truck. That’s the difference between a quote and a schedule: parts on hand, not a backorder notice.
Our Roofing Services in Half Moon Bay
Roof Repair
Roof repair in Half Moon Bay runs $400 to $1,800 for most jobs, and the majority start as a drip near a chimney flashing, a skylight curb, or a rusted valley. Salt-laden marine air corrodes galvanized flashing and fasteners within five to eight years here, faster than inland homes ever see. We replace damaged sections with hot-dipped stainless fasteners and heavier-gauge flashing so the fix doesn’t come back in three years. Call (877) 610-1318 and we’ll send a crew to inspect, photograph the damage, and hand you a written line-item quote before any work starts.

Roof Replacement & Installation
A full roof replacement in Half Moon Bay typically runs $8,000 to $20,000, and the spread comes down to roof pitch, deck condition, and whether the Coastal Commission wants plan review. Most reroofs here are not simple tear-offs: the older wood-framed cottages and ranches from the 1950s and 60s hide rot in the sheathing, sill plates, and rafter tails that salt air and fog drip have been eating for decades. We inspect the deck first, then write an allowance for any remediation into the contract. If the rot we find exceeds that allowance, you get a written change order before one extra nail moves. That’s how we keep a roof job honest. You can browse our full Roofing in Half Moon Bay service area to see coverage details.

Standing Seam Metal Roof
Standing seam metal roofs are the better long-term choice for much of Half Moon Bay, and they run $15,000 to $40,000 installed. The reason is simple: a properly detailed standing seam roof with stainless fasteners and marine-grade trim resists salt corrosion and fog drip far longer than the best architectural shingle. On a 1950s ranch near Miramar, our crew opened the eaves for a simple reroof and found salt-rotted sheathing and sill plates that had turned to sponge from decades of fog drip. We wrote a change order, swapped in pressure-treated lumber and hot-dipped stainless fasteners, and finished the standing seam roof before the Coastal Commission’s review clock expired. That’s the kind of job Half Moon Bay throws at you, and it’s why we keep a standing seam crew on the coast regularly.

Tile Roofing
Barrel tile roofs are common here, and tile roof repair in Half Moon Bay runs $600 to $2,500 depending on how many tiles are cracked, how much underlayment has failed, and whether the valley metal has rusted through. Fog drip saturates tile underlayment year-round, and when the felt rots, leaks can travel ten feet before they show up as a stain inside the house. We walk the roof, map the water path, and quote the repair scope in writing. If the deck underneath is gone, you’ll know before you sign, not after. No surprises, no allowances that aren’t on paper.

Trusted Brands We Service in Half Moon Bay
We install and repair premium materials from GAF, CertainTeed, and other name brands you can look up, not mystery stock off a van. For tile roofs we work with the manufacturers whose profiles hold up to coastal weather, and for metal we specify standing seam systems with marine-grade coatings. Because we serve Half Moon Bay regularly, we keep common flashing profiles, fasteners, and underlayment on the truck and in local supply lines, so a leak repair near El Granada doesn’t wait a week on a shipping label. The material you see on the quote is the material that shows up on the job.
Common Roofing Problems We See in Half Moon Bay Homes
- Rusted flashing and hidden chimney leaks. The same salt air that pits your car’s chrome eats galvanized roof flashings within five to eight years. By the time a leak shows on the ceiling, the flashing has been rusted through for a season or more. We replace it with heavier-gauge or stainless stock, not the same thin stuff that failed.
- Fog drip rot at the eaves and drip edges. Cypress and eucalyptus along the coast keep rooflines damp even with no rain in the forecast. Standard underlayment rots early and allows water into the deck at the very edge of the roof. If your roof looks wet every morning from June through August, that’s fog drip, and it’s cutting years off the roof’s life.
- Coastal Development Permit stop-work orders. Roofers who skip the coastal zone check get a red tag mid-job, leaving exposed sheathing during the dampest months and a frozen draw schedule. We verify the Coastal Commission status before we tear anything off. Every eligible job gets the permits and inspections, so you never eat a stop-work order from someone else’s shortcut.
- Salt-corroded fasteners under the shingles. The nails and screws holding your roof together rust invisibly from the underside. When a re-roof pulls back shingles, we routinely find fasteners reduced to powder along the coastal exposure. That’s why we specify hot-dipped or stainless fasteners on every Half Moon Bay job, not just the fancy ones.

FAQs - Roofing in Half Moon Bay
Most of Half Moon Bay’s developed area sits inside the California Coastal Commission’s coastal zone, so reroofing often triggers a Coastal Development Permit on top of standard city permits, and nearly every project needs an exemption determination before work starts. We check the property’s coastal zone status and the specific Coastal Act trigger before we tear anything off. Call (877) 610-1318 if you want us to pull your parcel and check the permit path, free.
Roof repair in Half Moon Bay costs $400 to $1,800 while a comparable inland repair may run lower, because salt air and fog drip have usually done deeper damage under the surface, and the Coastal Development Permit review adds planning time. We’d rather show you a honest local number than a cheap one that won’t survive one coastside winter. Call (877) 610-1318 for a written line-item quote and you’ll see exactly where the money goes.
Sometimes yes, and we’d need to inspect the deck before we promise it, but in Half Moon Bay it’s common to find rotting sheathing, sill plates, or rafter tails under shingles that looked fine from the outside. If the deck is sound, we quote the reroof at the replacement price. If it’s not, you’ll get a written allowance and a change order before the work, not a surprise bill at the end. Call (877) 610-1318 and we’ll inspect before you commit.
We write a rot allowance into the original contract so you know what remediation may cost, and if the actual damage exceeds that allowance, we stop and hand you a written change order before we spend another dollar. You approve it in writing, or we don’t do it. That’s how we handle every surprise on a Half Moon Bay roof, and it’s why the final number is never a mystery. Call (877) 610-1318 if you want to see how this works on your roof.
Standing seam metal with stainless fasteners and marine-grade trim holds up longer than anything else we install on the coastside, followed by properly detailed tile roofs with upgraded underlayment. Fog drip and salt air eat standard shingles and galvanized flashings years before their warranty would suggest. We’ll quote you metal, tile, and composition options with real numbers so you can decide based on lifespan, look, and what the Coastal Commission will approve. Call (877) 610-1318 for a free estimate.
