Fast, Reliable Roof Replacement Across Arcadia
Roof replacement in Arcadia typically costs between $9,500 and $22,000 for a standard single-story ranch, with architectural shingle work on a 1,600-square-foot roof landing around $13,500 to $16,000. The job usually takes three to five working days once materials arrive, and permitting here runs through Los Angeles County rather than a city building department. If you’re looking at water damage, curling shingles, or a roof past its useful life, call (833) 589-7850 and we’ll give you a straight answer about whether you actually need a full replacement or a targeted repair.
We work across Arcadia every week, from the 91006 flats near Baldwin Avenue to the 91007 foothill streets climbing toward Chantry Flat Road. Our crew knows this housing stock well: post-war ranches with original shake, mid-century bungalows with aging composition shingle, and the newer custom builds hugging the 210 corridor. That local familiarity means we scope the job correctly the first time, not from a satellite image.
Why Bedrock Roof Repair Is Arcadia’s Preferred Roof Replacement Company
Our name says the sequence: repair when possible, replace when necessary, inspect before either. Alan Cofield built Bedrock Roof Repair around that principle, and it’s the reason Arcadia homeowners call us after another contractor already told them a full tear-off was the only option. Sometimes the roof genuinely needs replacement. More often than people expect, a valley flashing or a few lifting shingle tabs can be fixed for a fraction of the quote.
We’re not tied to a single manufacturer’s product line. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means our material recommendation follows what your roof actually needs, not a supplier incentive. Seven leading brands. One honest recommendation. That flexibility matters in Arcadia, where one street might hold a 1958 ranch that needs a careful overlay-compatible repair and a 2019 custom build that needs a fully warranted replacement to county standards.
When you call about roof replacement in Arcadia, you’ll get Alan or a senior crew lead on the line, not a call center. We schedule inspections around your availability, and we show up with a ladder, a moisture meter, and a camera, not a sales script. If the roof has five more years in it, we’ll tell you that and document what to watch. If it has to come off, we’ll explain exactly why, line-item by line-item.

Flat Roof Replacement in Arcadia
Flat roof replacement in Arcadia shows up most often on the mid-century bungalows and 1960s ranches in 91006 and 91077, where original built-up or torch-down roofs have finally exhausted their service life. Arcadia’s long dry summers bake these membranes until they crack and alligator, and when a winter atmospheric river arrives, those cracks open into leaks that track straight into the ceiling. The job involves stripping the old membrane, inspecting the sheathing beneath, repairing any water-damaged decking, and laying a new membrane system, typically a modified bitumen or TPO depending on the slope and roof access.
A flat roof replacement in Arcadia runs $8,000 to $15,000 for a typical 1,200 to 1,800 square foot roof, with the higher end reflecting tear-off of multiple old layers, new tapered insulation, or rerouting roof penetrations. If you have a flat section on the back of a ranch that ties into a pitched front roof, that transition point is where we spend the most time scoping, because it is the leak source on nine out of ten Arcadia flat roofs we replace.
Roof Decking Replacement
On older Arcadia bungalows, the decking under a flat roof is often 3/8-inch plywood or even spaced boards that have rotted at the seams where the old membrane failed. We replace rotted or delaminated decking panels before the new membrane goes down, because a new roof over bad decking is a callback in waiting. County inspectors in Arcadia require the decking to be sound before final inspection, so we never skip this step to save a few dollars.
Flat-to-Pitch Conversions
Some Arcadia homeowners with flat roofs near the foothills ask about converting to a pitched roof to solve recurring ponding and leak problems. We can do that. The permit path goes through Los Angeles County for structural changes, and we handle the plan notes, shear calculations, and inspection scheduling. It costs more than a flat roof replacement, but for a 91007 home that has leaked every winter for a decade, it often ends the cycle permanently.
Roof Installation in Arcadia
Roof installation in Arcadia covers two situations: new construction on the larger custom rebuilds going up along the 210 corridor, and full tear-off-and-replace work where we remove everything down to the rafters and build the roof system back up. On new builds, we work from engineered drawings, install the decking with shear-approved nailing patterns, and coordinate with the general contractor’s framing and stucco schedule. On a full replacement, roof installation means the entire assembly: decking, underlayment, flashing, shingles or tile, vents, and edge metal.
New roof installation on a custom Arcadia build typically runs $18,000 to $45,000 depending on material choice, roof geometry, and the number of penetrations. The big cost drivers on hillside lots are crane access, steeper slopes that require additional fall protection, and heavier material choices like clay tile or standing seam metal that meet fire-hardening requirements in the foothill interface zones.
Architectural Shingles
Architectural shingles are the standard choice for most Arcadia replacements because they carry a 130 mph wind rating when installed with a six-nail pattern, which matters during fall Santa Ana events at the base of the San Gabriels. We install them from GAF, CertainTeed, and Owens Corning, and we can show you physical samples before you commit. The laminated construction holds up better to UV degradation than three-tab, which makes a real difference in a rain-shadow climate with 280-plus sunny days a year.
Asphalt Shingles
For tighter budgets on the older 91006 rental stock, basic asphalt shingle systems still work, provided the underlayment and flashing are done correctly. We use the same ice and water shield in the valleys and the same drip edge on a basic asphalt roof as we do on a premium architectural job. The materials cost less. The critical details do not change.
Trusted Brands We Service in Arcadia
We install and service roofs from GAF, CertainTeed, and Owens Corning, plus IKO, Atlas, Tamko, and Boral when the job calls for a specific profile or a tile that matches an existing Arcadia home. Because we stock common flashing, drip edge, and underlayment locally, we aren’t waiting on a supply house delivery to start your roof replacement. If you need a warranty claim on an existing roof, we can assess it against the manufacturer’s installation requirements and tell you honestly whether it’s a material issue or an installation issue. For Arcadia homeowners, that often saves a second trip from a manufacturer’s rep.

AfterCommon Roof Replacement Problems We See in Arcadia Homes
- Santa Ana wind stripping on aging shake roofs. In the 91006 and 91007 foothill blocks, every fall the dry winds pull tabs off old wood-shake and lift the edges of worn composition shingle, exposing underlayment right before the first winter storm. We front-load our Arcadia replacement schedules between October and December to catch this before leaks start.
- Missing or inadequate ice and water shield in valleys. Many original ranch roofs in Arcadia were built before ice and water shield was code, so heavy winter rain drives water up and under the valley flashing, into the soffit, and down the fascia. We see it constantly on 1950s and 1960s homes where the roof hasn’t been touched since construction.
- Hillside rebuilds reusing old decking. Some Arcadia hillside custom homes sit on older framing where the original decking doesn’t meet current shear or nailing requirements. When strong winds hit those slopes, shingles blow off in sheets because the decking beneath was never rated for uplift. We verify decking condition and nailing pattern before we quote.
- Chimney and skylight flashing failures on mid-century bungalows. Arcadia’s stock of post-war bungalows often has original masonry chimneys and old curb-mounted skylights where the flashing has corroded or separated. Those are the first leak points in a heavy rain, and they get re-flashed properly as part of any roof replacement we do.
Pricing for Roof Replacement in Arcadia, CA
Here are the numbers we quote most often in Arcadia. A basic asphalt shingle replacement on a 1,500-square-foot ranch runs $9,500 to $13,000. Architectural shingles on the same home land at $13,500 to $16,500. A flat roof replacement on the mid-century stock runs $8,000 to $15,000 by size and membrane. A full tear-off with decking repair on a hillside 91007 home with clay tile or Class A materials runs $20,000 to $35,000 and up depending on access and geometry. These are installed prices including tear-off, underlayment, flashing, permits, and haul-away. What moves the number: the square count, the number of roof planes and penetrations, whether the decking is sound, and whether the lot requires crane work or hand-carrying materials up a slope.

FAQs About Roof Replacement in Arcadia
Santa Ana winds in Arcadia’s foothill blocks routinely strip aging wood-shake tabs and lift shingle edges between October and December, so we recommend homeowners schedule roof replacement before the wind season starts, and we install all shingles with a six-nail high-wind pattern and reinforced flashing at the eaves and rakes to meet 130 mph uplift standards. If your roof has already lost tabs, we can usually repair the damaged sections and defer a full replacement if the underlayment is still intact. Call (833) 589-7850 to schedule an inspection before the next wind event.
Yes, because the long dry summers and intense UV exposure in the San Gabriel Valley degrade asphalt shingles faster than in coastal microclimates, which means we lean toward architectural shingles over three-tab for most Arcadia replacements, and we pay extra attention to UV-stable underlayment and metal flashing details. In the 91007 foothill interface zones, fire-hardened Class A assemblies with tile or standing seam metal are often the better choice for both safety and longevity. The rain-shadow also means the roof spends most of its life in dry heat, so we use sealants and adhesives rated for high thermal cycling. Call (833) 589-7850 and we’ll walk you through what makes sense for your specific roof.
Roof replacement in Arcadia goes through Los Angeles County building and safety, not a city permit office, and we pull the permit, schedule the inspections, and stand with you through final sign-off. The county requires a permit for any roof replacement, and the inspector will check decking condition, underlayment, nail pattern, and flashing details before the roof is closed up. We have done this in Arcadia for years and know exactly what the inspectors look for, which keeps the job moving. The permit cost is included in our written quote.
A square is 100 square feet of roof surface, and roof replacement quotes in Arcadia are priced per square because that’s how shingles, underlayment, and decking are sold and how labor is calculated. A 1,600-square-foot ranch has roughly 16 squares of roof area, though roof pitch and overhangs can change that number. When you get a quote from us, the number of squares is listed on the line-item sheet along with the per-square material and labor rate, so you can see exactly where the money goes. Call (833) 589-7850 if you want us to walk the roof and count your squares, which we’ll do for free.
Yes, we do flat-to-pitch conversions in Arcadia, usually on mid-century bungalows where a flat section at the back has leaked repeatedly or where the homeowner wants attic space and better drainage. The job involves removing the flat membrane, reinforcing or replacing the decking, adding a structural slope and trusses, and then installing the new pitched roof system, all permitted through Los Angeles County. It costs more than a flat roof replacement because it changes the structure, but it permanently eliminates the ponding and leak problem. Call (833) 589-7850 and we’ll tell you whether your specific lot and framing can support the change.
