We’ve worked on 1950s ranch houses off Foothill Boulevard and custom hillside homes in 91741 where the driveway won’t hold a lift. We know the difference between a flatland reroof and a Chapter 7A fire-zone replacement. That distinction matters here more than almost anywhere else in the San Gabriel Valley.
Barrett & Sons Construction is owner-operated. Tom Barrett’s sons run the crews. When you call about a roof in Glendora, you’re not getting a dispatcher in another state. You’re getting the people who will actually stand on your roof.
Why Barrett & Sons Construction Is Glendora’s Preferred Roofing Company
We’ve been pulling permits in Glendora’s building department long enough to know what the plan checker will flag before she flags it. North of Baseline Road, that usually means Chapter 7A Wildland-Urban Interface requirements. South of the 210, it’s more often structural questions on 1960s rafter tails. Either way, we walk into the permit office knowing which conversation we’re about to have. That saves you weeks.
Our Glendora customers call us back because we do what we said we’d do at the price we said we’d do it. Every scope change comes as a written change order before work happens. The allowance that isn’t on paper is a surprise waiting for a date. Tom’s been running jobs this way since 1998, and the 90-Day Done Right Promise is written on every contract. If something’s not right, Tom comes back and makes it right. One call.
We also know Glendora’s lots. Some of these hillside properties have 30-foot slopes and no street frontage for staging. Some flatland homes share a driveway with a neighbor who’s already had one bad contractor experience. We plan access before we quote, because access drives cost. That’s the honest conversation most roofers never have with you.
You can verify everything we claim. Tom Barrett publishes his name, his address, and his license number. Look it up before you sign anything. Ask anyone on your street.
Our Roofing Services in Glendora
We are a full-service Roofing contractor serving Glendora’s flatland tract homes and foothill custom properties. Here’s what we handle most often in this city:
Roof Repair
Roof repair in Glendora runs $400-$1,800 for most jobs. We see a lot of lifted shingles and flashing failures after Santa Ana wind events, especially in the hillside corridors where winds funnel through the canyons. Repair scoping here is different than in Covina or West Covina. In fire-zone areas, a small repair may still need to match the existing Class A assembly. We’ll tell you before the permit gets pulled whether that’s the case.
Never ignore a small leak on a Glendora hillside home. Water against a slope foundation causes erosion problems that go well beyond the roof.

Roof Replacement & Installation
A full roof replacement in Glendora costs $8,000-$20,000 depending on slope, layers, deck condition, and whether the home sits north or south of Baseline Road. The fire-zone homes carry extra requirements: Class A assemblies, ember-resistant vents, and often ignition-resistant fascia. Those are real costs, and we put them in writing on the front end. Not as a surprise at the final invoice.
Flatland ranch homes from the 1950s and 1960s often have original skip sheathing that needs attention before the new roof goes down. We check before we quote, because guessing is how change orders turn into arguments.

Metal Roofing
Metal roofing is a serious option in the 91741 hillside neighborhoods. It meets Class A fire ratings, it stands up to Santa Ana winds, and insurers across the San Gabriel foothills are increasingly requiring it as a condition of policy renewal. Metal roof installation in Glendora runs $15,000-$40,000.
We install standing seam systems that last decades, and we coordinate the CalFire ember-resistant vent inspections that Glendora’s building department wants before final sign-off. That coordination alone is worth the price of working with a local contractor who’s done it before.

Tile Roofing
Barrel tile roofing is common throughout Glendora, particularly on the ranch-style homes that dominate the flatlands. Tile heats up slowly, holds up well under intense summer sun, and fits the neighborhood aesthetic. Tile roof repair runs $600-$2,500 depending on whether we’re replacing broken tiles, re-bedding ridge caps, or addressing flashing failures underneath.
One thing we tell every Glendora homeowner with tile: don’t walk on it. Tile cracks under foot traffic even when it looks solid. We use ladder hooks and walk boards, and we check the underlayment because tile roofs fail underneath long before they fail on top.

No warehouse lag, no excuses.
Common Roofing Problems We See in Glendora Homes
- Santa Ana wind damage on hillside exposures. The same wind patterns that produced the Colby Fire in 2014 rip shingles and flashing off north-facing slopes every fall. We see more wind-related repair calls from Glendora’s 91741 than from anywhere else in our service area.
- Dry-rot on rafter tails and fascia. Homes built in the 1950s and 1960s across Glendora’s flatlands are now sixty to seventy years old. Exposed rafter tails get sun-baked and cracked, then winter rains get in. Hidden rot changes a reroof scope from a cap sheet to structural carpentry.
- Underlayment failure on tile roofs. That old barrel tile looks great from the street, but the felt underneath from the original build is often disintegrating. Water gets through, travels along the deck, and stains ceilings far from the actual leak. We find this on ranch houses all over Glendora.
- Chapter 7A compliance gaps on older hillside roofs. A lot of homes north of Baseline Road still have materials that predate the current fire codes. Homeowners often find out during the inspection process that the roof they thought was fine doesn’t meet minimum requirements. We walk you through exactly what Glendora’s building department expects before you spend a dollar.
Staging and Access on a Tight Glendora Lot
This is the part most roofing quotes in Glendora gloss over, and it’s the single biggest variable between a clean job and a nightmare. Many flatland homes in Glendora sit on narrow lots with shared driveways. Many hillside homes have no real street frontage at all. If materials can’t be staged on your property, that changes the labor plan. If a lift can’t reach the roof line, panels and tiles get hand-carried. That changes the schedule and the price.
We replaced a 1960s wood-shake roof on a tight 91741 hillside lot near the Colby Fire scar with a standing-seam metal system rated Class A. Our crew hand-carried panels up a 30-foot slope because the driveway couldn’t hold a material lift. We coordinated a CalFire ember-resistant vent inspection before the city would sign off. The owner’s insurer required the metal roofing as a condition of policy renewal, and we documented every change order in writing when hidden rot in two rafter tails pushed the scope beyond the original bid. That’s how jobs go in the foothills.
Blocking a neighbor’s narrow driveway is how stop-work orders happen. We don’t do it. We stage materials on your property when possible, use hand-carry methods when necessary, and talk to your neighbors before a single bundle gets delivered. It’s basic respect, and it keeps the job moving.
Noise matters too. Glendora has work-hour ordinances, and we stick to them. Your neighbor works nights? We’ll let you know the schedule up front so everyone’s on the same page. The permit inspector works for you, not for me. That’s why we like him.

We put all of that in a written line-item quote before you agree to anything. Every permit pulled, every inspection signed, every change order in writing.

FAQs - Roofing in Glendora
Yes, in most cases any repair north of Baseline Road that touches the roof assembly will trigger Chapter 7A review for the affected area. The city requires Class A materials and ember-resistant vents in the Very High Fire Hazard Severity Zone, and a partial repair that introduces non-compliant materials will fail plan check. We verify before we quote so you don’t pay for a design that won’t pass. Call (877) 610-1318 and we’ll check your specific property.
We plan access before the quote. On flatland homes with shared driveways, we coordinate staging times with neighbors and keep materials on your property. On hillside lots, we hand-carry when a lift can’t reach. Blocking a neighbor’s driveway is never an option. It’s how work stops.
North of Baseline Road, expect a geotechnical report requirement for grading and often a WUI materials sign-off involving CalFire for ember-resistant venting. These are above and beyond a standard reroof permit. We pull all of it, get the inspections signed, and line-item the costs in writing before work starts.
Fall wind events bring new damage calls. If your home falls in the hillside corridors, our schedule tightens that season. We’ll give you honest sequencing. Emergency tarping and repair work takes precedence. The phone is answered live 24/7 at (877) 610-1318.
Not automatically. Flatland ranch homes south of the 210 can often use a standard asphalt composition shingle. Hillside homes in 91741 must meet Chapter 7A Class A assembly requirements, which narrows the material list. We’ll tell you which materials pass on your street before you spend a dollar.
