AfterFast, Reliable Roof Replacement Across Half Moon Bay
Roof replacement in Half Moon Bay runs $14,000-$28,000 for a typical asphalt shingle roof on a 1,500-2,200 square foot home, with architectural shingles on the upper end of that range. Full tear-off and reroof usually takes four to seven working days once materials land. If you call (945) 303-9821, a live person answers, and we’ll schedule a walkthrough at your home in Half Moon Bay to give you a written price before any work starts. Tilehurst Roofing is a Kingswell family company, and our crews know the marine layer here better than most because we’re on these roofs every week.
We work throughout Half Moon Bay, from the Old Town historic district to the tract neighborhoods east of Highway 1, from Miramar to Frenchmans Creek. When a homeowner calls us about a failing roof, the first thing we check is whether the flashing, drip edge, and underlayment are still doing their jobs. In this town, they often aren’t, even when the shingles on top still look presentable. That is the Half Moon Bay difference, and we’ll explain it in plain language when we walk your roof.
Why Tilehurst Roofing Is Half Moon Bay’s Preferred Roof Replacement Company
A roof replacement here is not the same job as it is 15 miles inland in Burlingame or Millbrae. The daily marine layer keeps roof decks damp for weeks at a stretch, and onshore Pacific wind drives salt spray up the roof pitch. Standard galvanized drip edge and flashing rust through within a few years of that exposure. We see it on nearly every tear-off we do in Half Moon Bay. Greg Holloway, who leads our team, has walked enough of these roofs to know that the real decision is not just which shingle goes on top. It is which components go underneath.
Our crews serving Half Moon Bay are background-checked, uniformed, and trained on the coastal failure modes specific to this fog belt. We stock stainless steel and aluminum flashing as standard for jobs here, not as an upgrade. We carry material options from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so you choose the product that fits your home and your budget, not whatever happens to be on the truck. And every call to Tilehurst Roofing is answered by a live person, 24 hours a day, seven days a week. No voicemail tree, no waiting until Monday.
New Roof Installation in Half Moon Bay
New roof installation in Half Moon Bay is the full replacement of your existing roofing system: tear-off down to the deck, inspection of the wood underneath, new underlayment, new flashing and drip edge, and new shingles or another roofing material installed over it. Most Half Moon Bay homeowners need this when their current roof is beyond patchwork, when the underlayment has failed, or when an original wood shake roof from the 1980s or earlier has finally given out. A new asphalt shingle roof in Half Moon Bay typically runs $14,000-$22,000, while architectural shingles land closer to $18,000-$28,000 depending on roof size, pitch, and decking condition.
Decking Inspection and Replacement
When we tear off an old roof in Half Moon Bay, what we find underneath often changes the plan. Chronic fog and moss growth mean decking is soft or rotten more often here than inland. We inspect every sheet, and if portions need replacing, that cost is priced in writing with a signed change order before we proceed. No surprises at the end.
Stainless and Aluminum Components as Standard
In Half Moon Bay, we do not install galvanized drip edge or flashing on a new roof. Salt-laden marine air eats through it in a few years. We quote stainless steel or aluminum as the baseline, because replacing rusted flashing five years into a new roof is a repair you should never have to pay for.
Reroofing in Half Moon Bay
Reroofing in Half Moon Bay often means laying a new roofing system over an existing one, or tearing off only the failed layers. The difference from a full replacement is scope: a reroof usually leaves the decking in place when it is still sound. A reroof in Half Moon Bay runs $10,000-$20,000 for asphalt shingles, depending on whether we do a single-layer overlay or a partial tear-off. The marine layer makes single-layer overlays risky here. Trapped moisture between layers will rot the deck from the top down, so we recommend tear-off whenever the existing roof is a wood shake or has moss damage.
Wood Shake Tear-Off
Half Moon Bay still has a lot of wood shake roofs from the 1970s and 1980s, and in this climate they fail at the underlayment first. The shakes can look dry on the surface while the paper underneath is saturated and the deck below is soft. A proper reroof starts with full shake removal, deck inspection, and a new underlayment system.
Moss Removal Before Reroofing
If moss has lifted shingle edges and trapped moisture under your current roof, we clean the roof surface and inspect for hidden rot before any new material goes down. Reroofing over moss-damaged decking is a waste of money. We will not do it, and we will show you exactly what we found.
Trusted Brands We Service in Half Moon Bay
Tilehurst Roofing is not locked into one manufacturer. We install and service roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so your material choice is driven by your home’s architecture and your budget. For Half Moon Bay’s salt-air environment, we often recommend GAF architectural shingles for their wind rating and moisture resistance, and Atlas or Tamko for homeowners who want a heavier dimensional look with good coastal performance. We keep common replacement parts and accessories stocked for fast turnaround on Half Moon Bay jobs, so a missing ridge cap or drip edge piece does not stall your project for a week.
Common Roof Replacement Problems We See in Half Moon Bay Homes
- Rusted galvanized drip edge and flashing: Direct onshore salt spray corrodes galvanized metal within a few years. Water wicks behind the fascia and into the roof deck, causing rot even when the shingles look fine.
- Moss and lichen colonies lifting shingles: The perpetual damp feeds moss that grows under shingle edges and traps moisture against the deck. This accelerates rot and shortens the life of standard asphalt shingles.
- Aging wood shake roofs failing at the underlayment: Many Half Moon Bay homes built before 1990 still carry wood shakes. The shakes wear slowly, but the old underlayment underneath fails first, leaking into the attic long before the shakes look bad.
- Soft fascia and soffit boards: Years of damp marine air and moss growth leave many Half Moon Bay fascia boards spongy. A proper roof replacement includes inspecting and repairing these, not just laying new shingles over the rot.
Pricing for Roof Replacement in Half Moon Bay, CA
A full roof replacement in Half Moon Bay runs $14,000-$28,000 for asphalt shingles on a typical home. Architectural shingles land on the higher end, as do complex roofs with steep pitches or multiple valleys. A reroof without full deck replacement runs $10,000-$20,000. What moves the number: roof size and pitch, whether the deck needs replacement, and whether we are tearing off wood shakes or asphalt. We write every price in a line-item quote before any work starts, and that is the price you pay unless you approve a written change order.

FAQs About Roof Replacement in Half Moon Bay
Galvanized steel corrodes rapidly in Half Moon Bay because the daily marine layer keeps roof surfaces wet, and onshore wind drives salt spray directly onto the metal. In our experience, galvanized drip edge and flashing rust through within three to seven years here, which is well inside the lifespan of any new shingle. That is why we quote stainless steel or aluminum flashing as the baseline for every roof replacement in Half Moon Bay. If you want an exact assessment of your current flashing, call (945) 303-9821 for a free roof walkthrough.
The coastal fog means any shingle installed in Half Moon Bay must handle prolonged dampness and resist moss and algae growth better than a product spec’d for an inland roof. We recommend architectural shingles from manufacturers like GAF, CertainTeed, or Owens Corning, which have denser construction and better moisture resistance than basic three-tab shingles. A lighter-colored shingle also helps, since it holds less heat and dries faster after the morning fog burns off. Call (945) 303-9821 and we’ll show you material samples and explain which hold up best on your specific roof.
Half Moon Bay’s housing stock from the 1970s through the early 1990s included a lot of wood shake roofs, and many are still there. In this climate, wood shakes hold moisture for weeks at a time and the old underlayment underneath fails long before the shakes themselves look bad. By the time a homeowner sees leaks, the decking is often already soft. A proper replacement means full tear-off, deck inspection, and a modern underlayment system. For a written assessment of your wood shake roof, call (945) 303-9821.
Your quote should include full tear-off, decking inspection, replacement of any rotted decking at a stated per-sheet price, new underlayment, stainless or aluminum flashing and drip edge, shingle installation, and cleanup. Tilehurst Roofing writes all of this as a line item before any work starts. If we find rotted decking during tear-off, that cost is already priced per sheet in your contract, and you approve the final number in writing before we cut anything. Call (945) 303-9821 for a free written quote on your Half Moon Bay home.
Moss on a Half Moon Bay roof is structural damage in slow motion. Moss holds water against the shingle surface, lifts the shingle edges, and traps moisture underneath where it rots the deck. On a wood shake roof, moss accelerates underlayment failure. We remove moss as part of the reroofing process, not as a separate upsell, and we inspect the deck underneath before any new roofing goes on. To find out how much moss damage your roof has already sustained, call (945) 303-9821 and we’ll do a free inspection.
