Fast, Reliable Roofing Across San Dimas
Roof replacement in San Dimas typically runs $8,000 to $20,000, while roof repair work stays between $400 and $1,800 depending on scope. Most San Dimas homes we see were built between the 1950s and 1980s, and plenty of them are now on their second or third roof. If you’re in the 91773 ZIP, you already know the foothills keep life interesting. Wind-driven embers, summer heat, and an aging stock of ranch-style tract homes mean a roof here earns its keep. Call Barrett & Sons Construction at (877) 610-1318 and Tom’s crew will give you a straight answer.
Why Barrett & Sons Construction Is San Dimas’s Preferred Roofing Company
Tom Barrett founded this company in 1998, and his sons run crews on most San Dimas jobs. You won’t get a national franchise dispatching strangers to your door. You’ll get Tom’s name, his address, and his license number, all published and verifiable. Ask anyone on your street, or look up the license number yourself. If a roof isn’t done right, the 90-Day Done Right Promise means Tom comes back and makes it right, one call. No fine print, no runaround.
We pull permits and get inspections signed on every eligible roofing job in San Dimas. Tom likes the inspector. The inspector works for you, not for him, and that’s exactly why he wants them on the property. A lot of San Dimas homeowners have been burned by contractors who said permits were optional. They aren’t, especially up in the hills where Chapter 7A fire code applies. Our office coordinates a local Los Angeles team that serves San Dimas, and when you call (877) 610-1318, a live person answers, not a voicemail box.
What to Look For in a San Dimas Roofer
You’ve probably already learned the hard way, or watched a neighbor learn it. A phone quote is a suggestion. A written scope is a commitment. Ask any contractor bidding your San Dimas roof these three questions, and you’ll split the pros from the sales teams fast.
First, ask who shows up. If it’s a rotating cast of subs, that’s a red flag. Our crews are Tom’s sons and their teams. You’ll see the same faces from tear-off to final inspection. That matters when you’re six months out and need a gutter tweak or a loose flashing sealed.
Second, ask what happens when the price moves. It happens. A rotted deck board, a cracked fascia, a vent that needs replacing. The difference is whether you hear about it after the fact or before. Barrett & Sons runs every single scope change as a written change order before work proceeds. An allowance that isn’t on paper is a surprise waiting for a date.
Third, ask if Chapter 7A means anything to them. If a roofer looks blank at that phrase, they don’t know San Dimas. Large portions of this city sit in California’s Very High Fire Hazard Severity Zone. The San Gabriel Mountain foothills meet developed neighborhoods here, which means any significant remodel or roof replacement must meet CBC Chapter 7A standards. Class A roofing, ember-resistant vents, ignition-resistant assemblies. Those requirements don’t exist a few miles south in Covina or West Covina, and a contractor who doesn’t know the difference will happily sell you the wrong roof.
Our Roofing Services in San Dimas
Here’s what we handle most often for homeowners in San Dimas. Every job starts with a free estimate and a written scope. No allowances hiding in the fine print.
Roof Repair
Roof repair in San Dimas runs $400 to $1,800 for most jobs. The typical call is a leak around a vent boot or a lifted section of flashing after a Santa Ana event. We also see a lot of cracked tiles on the hillside homes north of Bonita Avenue, where the wind funnels through the foothill corridors. Repair work here often means matching existing materials on a 40-year-old roof, and Tom’s crew carries GAF underlayment and matching supplies to keep the patch from looking like a patch.
Roof Replacement & Installation
A full roof replacement in San Dimas runs $8,000 to $20,000. The ranch tract homes off Arrow Highway and around Lone Hill Avenue tend to land on the lower end. The custom-graded hillside parcels up toward San Dimas Canyon Park run higher, mostly because of access difficulty and steeper roof pitches. Every replacement quote includes tear-off, disposal, underlayment, and a written line item for any deck repair we find. Nothing gets added to the final bill that wasn’t on a change order first.
Metal Roofing
Metal roof installation in San Dimas runs $15,000 to $40,000. Standing seam metal is the right call for homeowners in the Very High Fire Hazard Severity Zone, and we install plenty of it in the northern foothill neighborhoods. A Class A-rated standing seam roof with ember-resistant vents is simply a better fit for this geography than anything combustible. It also shrugs off the wind that roars through the canyon in October. If you’re pricing metal for a hillside home, plan for the permit review to include Chapter 7A compliance, and know that Barrett & Sons pulls those permits and walks them through to sign-off.
Tile Roofing
Tile roof repair in San Dimas runs $600 to $2,500, and barrel tile is everywhere here. The 1970s and 1980s builds favored it heavily, and those roofs are now hitting the age where sarking felt rots out underneath intact tiles. We see it constantly on streets around Foothill Boulevard and the older subdivisions near downtown. Tile repair is not a job for a handyman. Walking a tile roof wrong breaks more tiles than it saves, and the hillside homes add a fall hazard you don’t want to mess with. Let a trained crew handle it.
Trusted Brands We Install in San Dimas
We carry real brands you can look up. GAF shingles and underlayment on most replacement roofs. CertainTeed on select jobs. We don’t show up with mystery materials off a van. For San Dimas customers, we keep common GAF components locally available so a repair doesn’t wait a week on a distributor. That matters when a leak shows up in the middle of a wet December and you need it handled. We also handle Windows & Doors in San Dimas and Fence Installation in San Dimas if your project runs past the roofline.
Common Roofing Problems We See in San Dimas Homes
- Santa Ana wind damage. The foothill position channels wind-driven embers from the San Gabriel Mountains straight through residential zones during fire season. We regularly see lifted ridge shingles, torn flashing, and dislodged tiles after a strong Santa Ana event.
- Felt rot under intact barrel tile. The 1970s and 1980s tile roofs across town look fine from the street, but the sarking felt underneath has aged out. By the time water shows up on a dining room ceiling, the deck underneath has been wet for months.
- Ember-vulnerable vents and gaps. Homes in the Very High Fire Hazard Severity Zone need ember-resistant vents and sealed eaves. A surprising number of older San Dimas roofs still have open gable vents or unprotected mesh that a code inspector will flag immediately on any remodel.
- Hillside access complications. The custom-graded parcels in the northern foothills often have steep driveways, tight access, and roofs that require staging on slopes. It changes the labor math, and a flatland roofer who doesn’t know hillside work will underbid it and then struggle to finish it.
Pricing for Roofing in San Dimas, CA

Yes. We work the flatland ranch tracts off Arrow Highway and Lone Hill Avenue, the hillside parcels north of Bonita Avenue, and everything in between. The hillside work takes longer to quote because of access and grade considerations, but it’s work we do regularly in San Dimas. If your parcel falls under unincorporated LA County jurisdiction rather than City of San Dimas, we handle that dual-jurisdiction paperwork too.
It can. If your home sits in the Very High Fire Hazard Severity Zone, your roof project may need Class A roofing material, ember-resistant vents, and specific underlayment types to pass inspection. Those materials don’t add a lot on a straightforward repair, but on a full replacement they can move the number. We’ll tell you upfront whether your parcel triggers Chapter 7A requirements, because the city and county don’t always agree on enforcement, and it’s better to know before the plan-check process stalls. Call (877) 610-1318 for an exact quote, and we’ll verify your parcel’s zoning and fire code status for free.
San Dimas runs about the same as the neighboring foothill cities for flatland work, but the hillside parcels here can run higher because of access and Chapter 7A compliance. La Verne and Glendora have their own hillside pockets, but San Dimas has a higher concentration of Very High Fire Hazard Severity Zone homes, which means more of our quotes here include ember-resistant vents and Class A materials as standard, not add-ons.
Every completed Barrett & Sons roofing job is backed by the 90-Day Done Right Promise, written on the contract. If it’s not done right, Tom comes back and makes it right, one call. Manufacturer warranties on GAF materials apply as they would anywhere else, and we walk you through the paperwork at the end of the job. The permit record also stays with the property, which matters when you sell your San Dimas home.
