Fast, Reliable Roofing Company Across San Marcos
If you own a home in San Marcos built between 1985 and 2010, there’s a good chance your concrete tile roof is hiding a problem you can’t see from the ground. The tiles look fine. The underlayment beneath them is not. Most of the work we do in San Marcos right now is underlayment-only replacement, not full tear-offs. That changes the price, the timeline, and the questions you should ask any Roofing Company that walks your property. Call (945) 303-9821 for a straight answer before you sign anything.
Why Tilehurst Roofing Is San Marcos’s Preferred Roofing Company
We work in San Marcos every week, and we know exactly what the same-vintage tract homes in San Elijo Hills, Twin Oaks, and the neighborhoods around Cal State San Marcos are dealing with: failed felt underlayment hiding under visually intact concrete tile. Greg Holloway, who leads our crews, has walked enough of these roofs to know that lifting tile on a 1998 or 2004 build in San Marcos almost always reveals the same thing: cracked, dried-out 30-year felt that is leaching and no longer shedding water. Homeowners call us because they saw a stain, not because their tiles look bad.
Every job starts with a written price before any work starts. That is not a selling point we negotiate. It is how we operate. If we find underlayment failure during a repair, we document it, show you the photos, and quote the underlayment-only replacement separately. You will know the number before we order material. And every repair carries a written guarantee, handed to you before the crew leaves.
Free Roof Estimate in San Marcos
A Free Roof Estimate in San Marcos means we come out, walk the roof, and give you a written, line-item price for the actual scope your home needs. For most San Marcos homes right now, that scope is underlayment-only replacement: the tile is sound, the felt is not. We will not push a full tear-off just because it is a bigger ticket. If the tile can be re-set and re-fastened, we say so.
For reference, underlayment-only replacement on a typical 2,200-square-foot San Marcos tract home generally runs $7,500 to $14,000, depending on ridge footage, valley count, and how much tile re-fastening the current code requires. A smaller repair, like replacing a broken valley or re-sealing a chimney chase, usually lands between $400 and $1,200. We will give you the exact number in writing before anything is ordered.
What We Check During the Estimate
We lift tile in at least three locations, usually at the eaves, a valley, and a penetration. We document underlayment condition with photos. We check ridge cap fastening because Santa Ana winds channel hard through the San Marcos inland valleys and rip loose ridge caps every season.
What You Get After We Leave
A written estimate with the scope broken out line by line. No verbal ballparks. No price that changes at the door. If you decide to move forward, the contract price matches the estimate price. Period.
Roofing Contractor in San Marcos
A Roofing Contractor in San Marcos who knows this city will ask about your home’s vintage before quoting anything. The 1985-2010 master-planned buildout means entire neighborhoods of San Marcos are aging on the same schedule, and that changes how we scope work. It also explains why we often recommend underlayment replacement while the tile stays put, which is not the default conversation older North County cities get.
When your roof is leaking at a valley or a wall flashing on a same-vintage tile roof, the leak is almost always the felt, not the tile. We will open the affected area, confirm what failed, and replace the felt, ice and water shield, and fasteners in that section. If the failure is widespread, we will tell you that. We will not sell you a full tear-off because it is easier to bid.
Builder Warranty Navigation
Some San Marcos homes, particularly 2005-2010 builds, sit under builder warranties that may still have teeth. We will document the failure and advise you whether to file through the builder or warranty channel first. Tearing into a roof under warranty without documentation can void what you are owed. We will not do that to you.
HOA and Architectural Committee Rules
San Marcos HOAs, especially in master-planned communities like San Elijo Hills, often enforce specific tile profiles and color ranges. Before any material is ordered, we confirm the product meets the community’s standards. You should not have to fight your HOA after the fact. We check first.
Trusted Brands We Service in San Marcos
We install and repair tile, asphalt shingle, metal, and flat roof systems from manufacturers we trust, including GAF, CertainTeed, and Owens Corning. For San Marcos homeowners, that means genuine material choice, not whatever is on the truck. If you live in a community with strict architectural guidelines, we can match the existing tile profile with the right manufacturer spec. Local parts for common San Marcos roof profiles are stocked at our San Diego dispatch and scheduling office, which keeps turnaround tight for San Marcos service calls.
Common Roofing Company Problems We See in San Marcos Homes
- Failed felt underlayment under intact concrete tile. The tile looks fine from the street, but the 30-year felt beneath has dried, cracked, and is no longer shedding water. This is the single most common call we get from San Marcos homeowners.
- Ridge cap mortar failure from Santa Ana wind events. Inland valley winds channel through San Marcos and work ridge caps loose season after season. We fast-check uplift fastening on every inspection because of this.
- Over-scoped estimates that push full tear-offs. A sound tile roof with bad underlayment does not need a tear-off. It needs underlayment-only replacement. We see San Marcos homeowners quoted full tear-offs daily.
- Builder warranty issues mishandled by other contractors. Opening a roof under warranty without documentation can void coverage. We document first, advise on the warranty channel, then proceed with your written go-ahead.

FAQs About Roofing Company in San Marcos
San Marcos grew in a compressed wave between 1985 and 2010, with master-planned neighborhoods like San Elijo Hills and Twin Oaks built almost entirely with concrete tile over 30-year felt underlayment. That means thousands of homes are hitting the 25-35 year mark on that felt at the same time. The tile is still sound, but the underlayment has failed. Underlayment-only replacement is the default correct scope here because the tile does not need replacing, the felt does. Nearby older cities developed incrementally, so their roof failures are spread across decades and mixed materials. Call (945) 303-9821 if you suspect your felt is failing.
It can, if the work is not documented or if materials are installed that conflict with the original builder spec. We photograph everything, document the failure point, and advise you whether to file through the builder or warranty channel before we open anything up. On 2005-2010 San Marcos builds, this step matters. We will not tear into your roof blind and leave you holding a voided warranty.
Upgrading the underlayment is the one that pays off most. When we replace failed felt, we install a modern synthetic underlayment rated for high-heat inland exposure, not another layer of the same 30-year felt that failed. Adding ice and water shield at valleys and penetrations also pays off, since those are the first failure points on San Marcos tract homes. Skip the tile replacement if your tile is sound. Spend on the waterproofing layer, not the pretty top layer. For an exact scope and price, call (945) 303-9821.
Most of the master-planned communities in San Marcos do require approval for material changes, and some require approval even for like-for-like replacement. We will confirm the community’s requirements and make sure the tile profile and color meet them before material is ordered. The last thing you want is a finished roof your HOA tells you to redo. We check first, every time.
Compare the scope line by line, not the bottom line. Look at whether the bid includes underlayment replacement or just patch work. Ask if the price is written and fixed before work starts. Ask if the crew fast-checks ridge caps for wind uplift. Ask what happens if the repair fails in six months. If the other company will not put the guarantee in writing before the crew leaves, that is your answer. We put every number and every guarantee in writing before any San Marcos roof is touched. Call (945) 303-9821 and we will walk your roof and show you exactly what your home needs.
