San Martin isn’t Morgan Hill. It isn’t Gilroy. It’s unincorporated Santa Clara County, with one-acre-plus parcels, barns, arena covers, and ranch homes that were built decades ago and haven’t had their roofs touched since. That changes how a roofing job should be scoped, priced, and scheduled. We scope it differently from the start.
Key Takeaways:
- Every San Martin roofing permit runs through Santa Clara County Building and Planning, not a city desk. We handle the paperwork.
- Most asphalt shingle repairs in San Martin run $450-$1,800. Full replacements on ranch homes run $14,000-$32,000 depending on square and pitch.
- Barn and outbuilding re-panels in corrugated metal run $4.50-$9.00 per square foot installed, and they almost always cost more than the ground-level quote.
- We answer the phone 24/7. A live person picks up. No voicemail, no callback queue.
Why Tilehurst Roofing Is San Martin‘s Preferred Roofing Company
Tilehurst Roofing is part of the Kingswell family of roofing companies, founded in 2000. Greg Holloway leads our local team, and he built our process around something most contractors in the South Valley ignore: putting the price in writing before the first nail goes in. San Martin homeowners have told us the same story again and again. A contractor quotes one number over the phone, sends a different one at the door, and the crew never comes back when the patch fails. We do the opposite.
Every job starts with a written price. Every repair comes with a written guarantee. If that repair fails inside the guarantee period, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it covers every job we do in San Martin, from full replacements on Llagas Avenue ranches to re-panels on hay barns off Foothill Avenue.
Our crews know the roads out here. We’ve brought material trucks down Oak Glen Avenue access drives, through stock gates on Fitzgerald Avenue parcels, and around gravel turnarounds on two-acre lots north of San Martin Avenue. Background-checked, uniformed technicians show up in the window we give. The estimate is free, and it’s a real number, not a teaser.
Roof Maintenance in San Martin
Roof maintenance in San Martin means more than cleaning leaves out of gutters. Because this valley sits near the Hecker Pass corridor, marine layer and coastal fog push in from the Salinas Valley more often than the inland map suggests. The result is damp roofs, long into spring, and moss, lichen, and algae growth on north slopes of asphalt and wood shake roofs across San Martin. A routine maintenance visit runs $250-$550 for most ranch homes, and it can add years to an aging roof.
Moss and Algae Control on North Slopes
The north slope of a 1960s ranch on the Llagas Avenue corridor is where the moss takes hold. When we do maintenance out here, we check the north-facing planes first. We remove moss and lichen manually, never pressure-blast shake or shingles, and we examine flashing, drip edge, and vent boot seals while we’re up there.
Fastener and Flashing Checks on Outbuildings
A barn roof that looks fine from the ground can be rusting through at every fastener. Routine maintenance on an agricultural building includes walking the whole panel run and checking each seam. If we catch degradation early, we can reseal or replace fasteners before the panel fails and the hay inside gets wet.
Roof Coating in San Martin
Roof coating in San Martin is a cost-effective way to extend the life of flat, low-slope, and metal roofs on ranch homes and outbuildings. Where summer temperatures hit the high 90s and winter fog keeps surfaces damp, a reflective coating reduces surface heat, slows thermal expansion, and seals small leaks before they open up. On low-slope sections of older San Martin ranch construction, coating runs $1.50-$3.50 per square foot depending on surface condition, prep time, and coating system.
Reflective Coatings for Low-Slope Ranch Sections
Older ranch homes in San Martin often have a low-slope section over an addition or carport. That’s where coatings earn their cost. The Hecker Pass moisture cycling stresses membrane seams, and a silicone or acrylic coating absorbs that movement while reflecting heat in summer. We inspect the decking for soft spots first. A coating over rotted wood is wasted money.
Coatings on Corrugated Metal Barns and Arena Covers
When a barn panel is still sound but the fasteners are starting to weep, we can coat the panel seams and fastener heads before a full re-panel is required. Coatings can buy three to five years on a roof that might otherwise fail the next winter. It’s a stopgap, not a cure. If the metal is thin or the structure is sagging, a re-panel is the honest answer, and we’ll tell you that before we sell you a coating.
Trusted Brands We Service in San Martin
Tilehurst Roofing installs and services materials from seven major manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters for San Martin homes because a wood shake replacement on a 1970s ranch has different requirements than an architectural shingle on a newer home off Foothill Avenue. We don’t sell what’s on the truck. We spec the product that fits the home, the pitch, and the budget. For barn and outbuilding work, we source corrugated panels locally and keep common GAF and CertainTeed accessories in our South Bay materials yard so turnaround on San Martin repairs stays fast.
Common Roofing Company Problems We See in San Martin Homes
- Original wood shake and three-tab shingles at end of life: Homes built from the 1950s through the 1980s across San Martin frequently still have their original roof. On the Llagas Avenue corridor especially, the north slopes hold moisture from the marine layer, and 40-year-old shake doesn’t get better with fog.
- Corroded fasteners on corrugated metal barns: Barns and arena covers installed in the 1960s through 1980s used basic fasteners with minimal sealing. Decades of ag dust and dew cycling on the valley floor have rusted those holes beyond what anyone can see from the ground. What looks like a patch job is usually a full re-panel.
- Flashing failures on low-slope ranch sections: The original flashing on a 1970s ranch addition sees extreme moisture-to-heat cycles every year. We find cracked sealant and separated step flashing at walls and chimneys more often in San Martin than in drier inland markets.
- Grading and drainage sending water back toward the slab: On one-acre parcels, the land slopes, and the water follows it. A roofer who treats San Martin like a dry tract-home market misses the way grade sends roof runoff back toward walkways and foundations, and we scope drainage with every quote.

FAQs About Roofing Company in San Martin
Santa Clara County Building and Planning issues all roofing permits in San Martin because the community is unincorporated. There’s no city building desk to walk into. We pull the permit, schedule inspections, and manage the paperwork as part of every full replacement and most repairs. On ag-exempt re-roofs for barns and arena covers, we confirm the exemption with the County before work starts so there are no surprises. Call (945) 303-9821 if you’re unsure whether your project needs a permit and want us to check.
Because the fasteners that looked fine from the ground are usually not fine up close. On San Martin barns built in the 1960s through 1980s, the original fasteners were often installed with minimal sealing, and decades of ag dust and dew cycling on the valley floor have rusted the holes well beyond what’s visible from below. We were called out to a ranch off the Llagas Avenue corridor where the client expected a patch on the hay barn. Our crew found nearly every fastener hole rusted beyond resealing. The job moved from a patch to a full re-panel within the first hour on the structure. We quote re-panels honestly before work starts, and we’ll show you the condition we found before we touch anything. Call (945) 303-9821 to get a barn roof assessment.
Yes. The Hecker Pass corridor funnels Pacific marine layer and fog from the Salinas Valley into the South Santa Clara Valley, and San Martin sits right in that path. Your roof stays damp longer in winter and spring than a roof ten miles inland. That means more moss, lichen, and algae on asphalt and wood shake, plus more stress on flashings and low-slope membrane sections. When we scope a San Martin roof, we treat it as a moisture-cycling environment, not a dry inland one. Call (945) 303-9821 for a maintenance check that accounts for the pass and what it does to a north slope.
We start with the house, then we walk every outbuilding, and then we look at access: gravel drives, stock gates, turnaround space, and where a material truck can park without wrecking the landscape or blocking a horse trailer. A one-acre San Martin parcel is not a tract homesite with a paved street and a 20-foot frontage. Long hauls from the staging area to the roof add cost, and that cost belongs in the quote before the first square lands. We also check grading and drainage so roof runoff isn’t directed back toward your slab or your stable. The estimate is free and it includes all of this. Call (945) 303-9821.
Look for cracked or separated sealant at flashing points, damp staining on the ceiling inside the addition, and any ponding water that doesn’t drain within 48 hours after rain. Low-slope sections on 1970s and 1980s ranches here see extreme moisture-to-heat cycling from the Hecker Pass fog and summer heat, and that’s where membrane seams fail first. If you spot any of these conditions, call us. We’ll inspect the decking, check the membrane seams, and give you a written price for repair or coating before you spend a dollar. Call (945) 303-9821 for a free estimate.
