Why Barrett & Sons Construction Is San Marcos’s Preferred Roofing Company
Tom Barrett started this company in 1998, and his sons run the crews. When you call, you talk to a person who knows San Marcos, not an out-of-state call center. Dispatch and scheduling are coordinated from our San Diego office; crews serve San Marcos locally, which means the person who shows up to look at your roof is the same person whose name is on the truck.
We pull permits on every eligible job in San Marcos. That matters here more than most places. The City of San Marcos building department sees a lot of out-of-area crews who get caught off guard by soils-report conditions tied to original mass-grading approvals. We don’t get caught off guard. We expect the unexpected, write it down, and put a price on it before we touch anything.
Homeowners in San Marcos have called us for everything from a missing barrel tile after a Santa Ana blow to a full reroof on a 2004 stucco tract home off Twin Oaks Valley Road in 92078. What they tell us they want is a straight price, a permit pulled, and a roof that passes inspection. That’s what we give them. Every job is backed by our written 90-Day Done Right Promise. If it’s not done right, Tom comes back and makes it right, one call.
Our Roofing Services in San Marcos
Roof Repair
Roof repair in San Marcos usually falls in the $400-$1,800 range. The most common call we get from homeowners in 92069 and 92078 is a leak that shows up as stucco staining on an interior ceiling. By the time the stain appears, water has usually been working its way through cracked underlayment or lifted flashing for weeks. Inland temperature swings of 30°F or more between day and night chew through caulk joints and flashing faster than the stable coastal air in Carlsbad or Encinitas. Roofing repairs on San Marcos hillside homes need to be diagnosed by someone who knows what inland thermal cycling does to tile underlayment.
Roof Replacement & Installation
A full roof replacement in San Marcos runs $8,000-$20,000. What drives that number up is what we find once the old roof comes off: failed waterproofing, undersized or damaged framing, and code upgrades a permit triggers. In the WUI zones, those upgrades are not optional. Much of the hillside in 92069 and 92078 is designated Wildland Urban Interface, and the City enforces CAL FIRE Chapter 7A requirements for Class A roof assemblies, ember-resistant vents, and noncombustible gutters on any permitted reroof or repair over 50% of the roof surface. A coastal Carlsbad crew might never have filed that paperwork. We file it, install it, and get the inspector to sign it.
Metal Roofing
Metal roof installation in San Marcos runs $15,000-$40,000. A standing seam metal roof makes a lot of sense on hillside lots where Santa Ana winds send sparks and debris across the chaparral. Class A fire ratings come standard with metal, which satisfies the WUI compliance requirements without needing a separate assembly rating. The catch is that metal on a settling graded pad shows movement more visibly than tile, so we check fascia alignment before we ever order material.
Tile Roofing
Barrel tile roofs on early-2000s tract homes are the single most common roofing system we see in San Marcos. The tile itself lasts decades. The underlayment under it does not. Cracked underlayment and lifted flashing from diurnal temperature swings let water in where nobody can see it until the ceiling stains. Tile roof repair in San Marcos runs $600-$2,500. When we do a full tile reroof, we use a modified bitumen underlayment rated for inland thermal cycling. The cheap felt that went on those 2004 homes was not.
Gutters & Accessories
Gutters on San Marcos hillside lots clog with chaparral debris faster than flatland neighborhoods. Overflow saturates the expansive clay subsoil around the foundation and puts pressure on retaining walls. We install oversized downspouts and leaf guards that handle chaparral debris, not just the occasional oak leaf. And in WUI zones, we install noncombustible gutter material that meets Chapter 7A, not the cheap vinyl that melts in a brush fire’s radiant heat.

Trusted Brands We Service in San Marcos
We install what we can stand behind. On a San Marcos barrel tile reroof, we’ve used GAF modified bitumen underlayments under original tiles because it handles the inland temperature swings better than anything else we’ve tested. For metal roofs, standing seam systems from the major manufacturers hold up to Santa Ana debris impact without denting the way cheap exposed-fastener panels do. If your existing roof carries a manufacturer warranty, we match accredited installation standards so that warranty doesn’t get voided by a careless tear-off.
Common Roofing Problems We See in San Marcos Homes
- Cracked underlayment on barrel tile roofs: Early-2000s tract homes across San Marcos were built fast, and the felt underlayment under those barrel tiles has a service life measured in decades, not forever. Thermal swings of 30°F+ open hairline cracks that let water in silently.
- Lifted flashing at roof-to-wall transitions: The same diurnal temperature cycling that cracks stucco also works flashing loose. Homes on mass-graded hillside pads move slightly, and flashing that was tight in 2004 is often gapped and leaking now.
- Chaparral-clogged gutters on hillside lots: Downspouts fill with dried brush in weeks during fire season. When they overflow, water saturates expansive clay subsoil, which shifts and puts pressure on retaining walls. That’s a roof problem that becomes a foundation problem.
- Lost Class A compliance from patch jobs: A common DIY fix in San Marcos is patching a small roof section with whatever shingle matches the color. What homeowners don’t realize is they’ve now voided their WUI Class A compliance. When the house goes up for sale, or a remodel pulls a permit, the inspector notices.
Pricing for Roofing in San Marcos, CA
Here’s what we quote San Marcos homeowners, in writing, before any work begins:
| Service | Price Range in San Marcos |
|---|---|
| Roof Replacement | $8,000-$20,000 |
| Roof Repair | $400-$1,800 |
| Tile Roof Repair | $600-$2,500 |
| Metal Roof Installation | $15,000-$40,000 |
What moves a San Marcos roof quote is what’s under the roof, not what’s on top of it. A house on a settled graded pad may need a soils engineer to sign off on foundation loading before the City issues a roof permit. A WUI reroof needs Class A components and ember-rated vents. Those things cost money, and they’re written into your allowance before we start. No surprise invoices at the end, because the allowance that isn’t on paper is a surprise waiting for a date. Call (877) 610-1318 for your free estimate, and we’ll put the numbers on paper.
We Also Serve Cities Near San Marcos
Beyond San Marcos, Barrett & Sons Construction works regularly in Escondido, Vista, Carlsbad, and Encinitas. The coastal marine layer protects Carlsbad and Encinitas from the inland thermal cycling we see in San Marcos, which means what’s true for a barrel tile roof here is not always what a coastal crew assumes. We know the difference.

FAQs - Roofing in San Marcos
Sometimes. If your home sits on a mass-graded pad, the City of San Marcos may tie the roof permit to the original grading approval, which can require a geotechnical engineer to verify compaction under the affected eave before the permit is issued. Out-of-area crews miss this. We plan for it. Call (877) 610-1318 and we’ll tell you if your lot is flagged.
A Class A roof is a fire-rated assembly, not just a shingle. In San Marcos’s WUI zones, your reroof must use an assembly that passes CAL FIRE Chapter 7A, which means the shingle, the underlayment, the vents, and the gutters all have to meet the standard. A standard composition shingle roof in a coastal city without WUI requirements may not. We pull the WUI checklist from the City before we write your scope.
They share a cause: San Marcos sits inland and sees 30°F+ temperature swings between day and night. The same expansion and contraction that cracks stucco also cracks roof underlayment and works flashing loose. A stucco crack and a roof leak often show up in the same wall section, and fixing one without checking the other leaves the real problem in place.
Expect us to tarp first and fix second. Santa Ana winds lift barrel tiles and tear flashing in minutes, and the leak gets worse in the dry heat afterward as cracks widen. We’ll get a tarp on the damaged section, document the damage for your insurance, and write the repair scope. Emergency storm damage repairs in San Marcos typically start around $400 and go up from there depending on how many tiles the wind took.
Because San Marcos swings 30°F or more between day and night while Carlsbad sits under the marine layer and barely moves. Constant thermal expansion and contraction crack standard felt underlayment in a decade or two inland. We use modified bitumen underlayment rated for that movement. It costs more upfront and leaks far less over time. Call (877) 610-1318 for an exact quote for your roof.
