Fast, Reliable Roof Replacement Across Alhambra
Roof replacement in Alhambra typically runs between $11,000 and $28,000 depending on material choice, square footage, and what the tear-off uncovers on these older homes. That last part matters more in Alhambra than almost anywhere else we work. Most roofs here sit on 1920s to 1950s Spanish Revival and Craftsman bungalows with original clay tile or wood shingle, and what’s underneath often changes the scope once we open things up. We plan for that. Call (866) 282-5070 for a free estimate and we’ll walk the roof with you before quoting, so you know exactly what you’re dealing with.

We know the streets. We know the 91801 and 91803 neighborhoods where mature Chinese elms and camphor trees shade the north slopes and hold moisture against the roof. We know the alleys off North Almansor where staging a tear-off takes real planning because the lots are tight and the garage is right up against the house. That local knowledge keeps the job moving and keeps surprises visible before they become change orders.
Why Buena Park Roof Repair Is Alhambra’s Preferred Roof Replacement Company
We work with seven major roofing manufacturers – not one. That matters in Alhambra because so many homes here have mixed-material roofs: asphalt shingle fields with original clay tile porches or accents that are no longer manufactured. A roofer tied to a single brand will struggle to match what you’ve got. We’ll pull from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, or Boral to find the closest possible match for your existing tile and shingle profile.
Our Roof Replacement crew is focused on one trade. We don’t do gutters. We don’t do siding. We do repair, replacement, and inspection. That focus means we’ve seen enough Alhambra tear-offs to know that a quote on a 1940s bungalow needs an allowance for hidden decking rot and framing repair before it’s honest. We build those allowances into the contract up front, in writing.
Rick Dunnigan leads our team, and his repair-first approach is the reason people in Alhambra call us before committing to a full replacement. If the roof can be repaired at a fraction of the cost, that’s what we’ll tell you. We’d rather give you an honest condition report than sell you a roof you don’t need.
Styles & brands we work with






Roof Replacement Contractor in Alhambra
A Roof Replacement Contractor in Alhambra has to handle more than tearing off old shingles and nailing up new ones. On the 1920s to 1950s housing stock here, full replacement frequently exposes rotted sheathing, undersized framing, and outdated wiring that the county inspector will flag once the roof is opened. The job becomes a structural repair as much as a roofing job. We plan for this before the first tile comes off.
What the Tear-Off Usually Reveals
North-facing slopes in the 91801 and 91803 ZIP codes stay damp for weeks after winter rain. Chinese elms and camphor trees shade those slopes and drop seeds that clog the valleys, so water sits against the eaves and the decking rots. From the street, the roof looks fine. Open it up, and you’ll often find water-logged planks under the original clay tile, failed underlayment, and framing that needs sistering or full replacement. We photograph everything and walk you through it before we change the scope.
Allowances Written In, Not Added On
A replacement quote should never be a best-case fantasy. On Alhambra homes, we write a written allowance for decking replacement and framing repair into the contract. If the tear-off reveals less damage than expected, you pay less. If it reveals more, we review the photos with you, price the added squares and framing in writing, and get your approval before we proceed. You’ll never get a surprise invoice at the end.
Asphalt Shingle Roof Replacement in Alhambra
Asphalt Shingle Roof Replacement in Alhambra generally runs $12,000 to $22,000 on a typical 1,400 to 2,000 square foot home, with architectural shingles at the higher end and three-tab at the lower. The shingles themselves are the least of the cost driver here. What moves the number is what we find under the old roof, and on homes with original tile over skip-sheathing, that can mean a full decking replacement before a single shingle goes down.
Matching What the Street Sees
Many Alhambra homes have already been re-roofed with asphalt shingles on the field but kept original clay tile on the porch and accents. When we re-shingle the field, we match the color and profile as closely as possible to the surviving tile so the house reads the same from the curb. Having seven manufacturers to pull from means we’re not forcing one brand’s limited palette onto your roof.

Underlayment and Ice and Water Shield
Because Alhambra’s winter rains concentrate runoff into valleys that are frequently clogged with leaf and seed debris, we’ll upgrade the underlayment at those valleys and add ice and water shield where the eave overhang is tight. It’s a modest material cost that prevents the exact failure mode these older roofs are known for.
Trusted Brands We Service in Alhambra
We install and warranty products from seven major manufacturers, which means you choose the material, not us. On Alhambra homes we’re often pulling from Atlas and Tamko for architectural shingles that match original tile colors, and IKO for lower-cost three-tab replacements where the homeowner wants a budget-conscious fix without sacrificing a 25-year warranty. Because we work directly with these manufacturers, turnaround on special-order colors is fast for Alhambra customers – typically a week or less from order to delivery at our Buena Park yard. You’ll never be told “this is what we have on the truck” unless it actually fits your roof and your budget.

AfterCommon Roof Replacement Problems We See in Alhambra Homes
- Rotted sheathing hidden under original clay tile. The tile looks fine from the street, but underneath, water that pooled in leaf-dammed valleys has rotted the planks. This only becomes visible after tear-off, which is why our quotes include a written allowance for exactly this.
- Mixed-material roofs with discontinued tile. A shingle field with a tile porch or accent creates a matching problem when the original tile is no longer manufactured. We work across seven brands to get the closest visual match and preserve the home’s curb appeal.
- Undersized or fire-damaged framing on 1920s to 1950s homes. Once the decking comes up, the inspector will check the framing. Old 2×4 rafters or previous fire damage often trigger a code upgrade that changes the scope. We price it in writing before proceeding.
- North-facing slope failure from tree shade and debris. On streets lined with Chinese elms and camphor trees, the north slope gets no sun, stays damp, and rots at the eaves. This is the most common reason a roof replacement on a 91801 or 91803 home turns out bigger than the homeowner expected.
Pricing for Roof Replacement in Alhambra, CA
A full Roof Replacement in Alhambra on a standard 1,200 to 1,600 square foot bungalow ranges from $11,000 to $19,000 for architectural asphalt shingles, and $14,000 to $28,000 when the scope includes full decking replacement and framing repair that the older housing stock here frequently requires. Flat roofing on the few mid-century modern homes in town runs $10,000 to $18,000 depending on the membrane system. The single biggest variable is the tear-off. A roof with original clay tile over skip-sheathing will cost more to open up than a roof that’s already been re-shingled with asphalt. We give free estimates with a written, line-item breakdown, and we never start a change order without your sign-off. Call (866) 282-5070 to schedule a walk-through.

FAQs About Roof Replacement in Alhambra
Because the original tile on many 1920s to 1950s Alhambra homes hides rotted sheathing underneath, especially on north-facing slopes where trees shade the roof and clog valleys with debris. The damage is invisible until the old covering comes off. That’s why we write a decking and framing allowance into the contract up front, and if the tear-off reveals more or less than expected, we adjust with photos and written approval before any added work starts. Call (866) 282-5070 and we’ll explain exactly what to expect on your roof.
We match it as closely as possible using field shingles from one of our seven manufacturers, choosing the color and profile that reads best against your surviving original tile. Alhambra is full of homes with asphalt fields and tile porches, so we do this constantly. We’ll show you physical samples on the roof before ordering. Call (866) 282-5070 to schedule a free sample-match visit.
A permit inspection on an older Alhambra home can trigger framing upgrades, fire code corrections, and in some cases electrical repairs once the decking is off and the structure is visible. We expect this on 1920s to 1950s bungalows and price for it in the original quote, with written allowances. We pull the permit, schedule the inspection, and walk you through whatever the inspector flags before any added cost is authorized.
Because the mature Chinese elms and camphor trees on many Alhambra streets shade the north slope and drop leaves and seeds into the valleys, holding moisture against the roof surface for weeks after winter rain. The street-facing side gets sun and stays dry. The north side rots at the eaves and is where we most frequently find failed decking once the roof is opened. We’ll photograph it and show you exactly what’s happening during the estimate.
Yes, we stage tear-offs and material deliveries from the alley or driveway rather than the street, which keeps the job moving on tight lots where the garage sits close to the house. We’ve done this on bungalows throughout 91801 and 91803, and we’ll plan the staging before we drop the first load. Call (866) 282-5070 to schedule a free site walk and we’ll map it out with you.
