AfterFast, Reliable Roof Installation Across Broadmoor
A full roof installation in Broadmoor typically runs $11,000 to $24,000, depending on whether you choose architectural composition shingles or a standing seam metal system. Homes built in the late 1940s and 1950s here often need decking repairs and framing reinforcement once the old layers come off, and those costs get approved in writing before we touch anything. If you’re wondering what a new roof should cost on your street off Broadmoor Drive or along Camaritas Avenue, call us at (743) 200-8347 for a free estimate with real numbers, not ballparks.
We know Broadmoor. We know the fog that sits on your roof for days in July, the composition shingles that never fully dry, and the county permit process that trips up out-of-town contractors. Our Roof Installation team works on Broadmoor homes year-round, and we coordinate every job through Grant Whitlock, who makes sure the price you’re quoted is the price you pay, with any change documented and approved before work begins.
Key Takeaways for Broadmoor Homeowners
- Roof installation in Broadmoor runs $11,000 to $24,000 for most homes, including tear-off, materials, and labor.
- Broadmoor is unincorporated, which means permits come from San Mateo County, not Daly City, and filing with the wrong jurisdiction is the most common delay we see.
- Most Broadmoor roofs were framed between 1946 and 1958, and the rafter sizing often won’t carry heavier systems without reinforcement.
- Every Mercer Roofing technician arrives in uniform with a photo ID badge, and their name and photo are sent to you before the visit.
- Written price before work starts, every single time, with no surprises on the invoice.
Why Mercer Roofing Is Broadmoor’s Preferred Roof Installation Company
Homeowners in Broadmoor call us because we treat a roofing job as something different from a door-to-door estimate and a handshake. The person who shows up at your door is someone you already know by name and face. Before any technician arrives, we send the name and photo of the person coming to your home. They badge in with a photo ID, in a clean, marked uniform. That’s the Threshold Standard, and every one of our technicians is background-checked and identity-verified under the Threshold Verified framework. It matters in a community like Broadmoor, where many of our customers are parents with young kids, older homeowners, or people who are home alone during the day and want to know exactly who’s walking up the driveway.
We work throughout Broadmoor, from the blocks off 87th Street to the homes near the Broadmoor Village shopping center. Our customers here tell us the same thing: the written price, the written guarantee, and the face at the door are the reasons they chose us over the cheaper bid. So we lead with those three things on every visit. It’s not a pitch. It’s just how we’ve done it since 2000, when Mercer Roofing was founded as part of the Threshold Group family of home-service companies.
Calls are answered by a live person, 24/7. Not a voicemail. Not a call-back request. When you call about a roof installation in Broadmoor, a real human picks up, takes down your address, and schedules a day that works for you. Dispatch and scheduling run through our Los Angeles office, but the crews who serve Broadmoor are local to the area and familiar with every street and alley in the village.
Shingle Roof in Broadmoor
A shingle roof in Broadmoor means tearing off the old composition layers that have been holding fog moisture for fifty or sixty years, inspecting the decking underneath, and installing a new architectural shingle system that actually has a chance to shed water and dry out. Most Broadmoor homes were built between 1946 and 1958, and the original roofs were designed for lightweight composition shingles with low-slope gable lines. When we install shingles here, we typically work with GAF Timberline or CertainTeed Landmark products, because they hold up better to persistent marine-layer moisture than the old three-tab shingles did. A standard shingle re-roof on a Broadmoor home runs $11,000 to $18,000, depending on decking condition and whether structural work is needed.
Decking and Underlayment Conditions We Find
On most Broadmoor homes, the old roof comes off and we find decking that’s been wet for a long time. The fog off the Pacific keeps the north and west planes damp for days after a rain, and we regularly replace sections of plywood or skip sheathing that look fine from the top but crumble the moment the old shingles are pulled. We write that decking allowance into the estimate before work starts, so the number you approve is the number that covers reality.
Ventilation and Moisture Control
Low-slope gable roofs with undersized soffit vents trap moisture under the new shingles, and that’s why we return to re-roof in Broadmoor sooner than the shingle warranty suggests. On every shingle job here, we evaluate the ridge vent and soffit intake, and we write a recommendation into the quote if the house needs more air moving through the attic. If you skip that step in this climate, the new roof can fail in ten years instead of twenty-five.
Standing Seam Metal Roof in Broadmoor
A standing seam metal roof in Broadmoor is one of the smarter upgrades you can make to a 1950s tract home, because the panels shed fog moisture and don’t hold the organic film that feeds moss and lichen the way composition shingles do. The catch is that most of these older Broadmoor homes weren’t framed to carry the weight of a metal system, and the rafter sizing frequently fails load checks once the decking is exposed. Expect a standing seam roof on a Broadmoor home to run $18,000 to $24,000, with structural reinforcement billed separately and approved in writing before a single panel is laid.
Load Paths and Structural Reinforcement
When we pulled the old composition layers off a 1951 stucco home off Broadmoor Drive this year, the rafters wouldn’t carry the new load without sistering and a partial ridge beam upgrade. The county inspector flagged it because the permit was already open, and we documented the reinforcement and had the homeowner sign the change order before we laid a single square of new material. That’s how it should work on every Broadmoor metal roof, not just the ones where the problem is obvious from the first inspection.
Panel Selection and Fog Performance
Standing seam panels hold up better here than shingles in one specific way: they dry fast. Broadmoor sits right in the fog belt, and the marine layer gets into granule surfaces and underlayment joints and stays there. Metal doesn’t absorb that moisture. We typically install Atlas or Tamko standing seam systems for Broadmoor homes, with high-temperature ice and water shield in the valleys and a ventilated ridge detail sized to the low-slope gable.
Trusted Brands We Service in Broadmoor
We install and repair roofs from the manufacturers that have proven themselves in coastal fog conditions: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Broadmoor homes, we stock local parts and commonly used profiles from GAF and Atlas, which means when you need a matching ridge cap or a specific flashing detail, we don’t wait a week for a warehouse order. That speeds up a re-roof on Broadmoor’s older homes, where a delayed material delivery can leave exposed decking sitting under fog for days. If you want a specific brand, we’ll quote it. If you want our recommendation for your street and your roof pitch, we’ll give you that instead, with the reasons written down.
Common Roof Installation Problems We See in Broadmoor Homes
- Fog-fed deck rot on north and west roof planes. Composition shingles on those surfaces rarely fully dry between fog events, so by the time a re-roof starts, the decking underneath is already failing. We write decking replacement into the estimate up front, because we find it on nearly every Broadmoor tear-off.
- Undersized 1946-1958 rafter framing. The post-WWII tract homes that make up Broadmoor were framed for lightweight shingles, not for heavier modern systems. If the framing won’t carry the load, we sister the rafters or add a ridge beam, document it in writing, and get your approval before we proceed.
- County permit confusion stalling the job. Broadmoor is unincorporated, so permits run through San Mateo County’s Building and Planning Department. Contractors who file with Daly City or assume no permit is needed for a re-roof of this size cause delays that can leave a torn-off roof exposed through several fog cycles. We file with the correct jurisdiction the first time.
- Poor ventilation trapping moisture under the new roof. Low-slope gable designs with inadequate soffit and ridge venting trap moisture under the new material, and the same failures come back years before the warranty would suggest. We address ventilation on every Broadmoor roof installation, even when the homeowner didn’t ask about it.
Pricing for Roof Installation in Broadmoor, CA
A full tear-off and re-roof on a Broadmoor home typically runs $11,000 to $18,000 for architectural composition shingles, and $18,000 to $24,000 for standing seam metal. The things that move the number here are decking replacement, structural reinforcement for heavier systems, and ventilation upgrades, all of which we write into the original estimate as line-item allowances.

FAQs About Roof Installation in Broadmoor
Yes, every roof installation in Broadmoor requires a permit, and it’s issued by San Mateo County’s Building and Planning Department, not by Daly City or any city hall, because Broadmoor is an unincorporated community. We pull that permit ourselves, and we file it with the correct jurisdiction the first time, so your job doesn’t stall mid-install when a county inspector arrives. Call (743) 200-8347 if you want us to check the current permit status for your specific address.
Sometimes, yes. Once the old roofing layers are off and the inspector sees open framing, current code may require structural upgrades like rafter sistering or a ridge beam, especially if you’re moving to a heavier system. We document every code-triggered change in writing and get your approval before we proceed, so the price never moves without your signature. The earlier you call, the faster we can get an inspector out and give you a real number.
Broadmoor sits in a coastal fog belt where the marine layer keeps roofs damp for days at a stretch, even in summer, and the north- and west-facing planes almost never fully dry out. That persistent moisture drives aggressive moss and lichen growth and accelerates granule loss on composition shingles, which means underlayment and decking degradation happen much faster here than in fog-shadowed inland cities like San Mateo or Redwood City.
Many Broadmoor homes built between 1946 and 1958 were framed for lightweight composition shingles only, and the rafter sizing often won’t carry a heavier modern system without reinforcement. We evaluate the existing framing before recommending materials, and if structural work is needed, we price it in writing and get your approval before we order a single panel.
It should include a line-item tear-off price, material costs for the specific shingle or metal system, decking replacement allowance, ventilation work, county permit fees, and a written workmanship guarantee that covers any installation defect for a full 365 days. If a quote doesn’t spell those out, you’re going to get change orders. Call (743) 200-8347 for a free estimate that shows every one of those numbers on paper before you commit to anything.
We started Mercer Roofing in 2000, and we’ve built the company around the idea that a roof is only as good as the trust you have in the person installing it.
