Fast, Reliable Roof Replacement Across South Whittier
Roof replacement in South Whittier runs between $11,000 and $22,000 for most of the 1950s-60s tract homes we see here, with flat roof work on the low end and full tear-offs with decking repair on the higher side. We’re in South Whittier regularly, working on the post-war bungalows off Telegraph Road and the ranch homes near the 605. Ruben Calloway leads our crews, and he’ll tell you straight whether a repair is enough or a full replacement actually makes sense. Call (855) 382-1073 for an honest look at your roof.
Why Barnwood Roofing Is South Whittier’s Preferred Roof Replacement Company
We’ve torn off enough old built-up roofs along Lambert Road and Gunn Avenue to know exactly what’s underneath them: original sheathing, failed flashing at carport tie-ins, and layers that were never meant to last sixty years. South Whittier homeowners call us because we don’t start with a sales pitch. We start with an inspection, then a recommendation. If your roof has five more years in it, we’ll say so.
Our Roof Replacement team handles the full job: tear-off, decking assessment, underlayment to county wind-load standards, and the new roof system itself. We pull permits through LA County Public Works and get every inspection passed before we call the job done. No handoffs, no subcontractor roulette. Ruben Calloway built Barnwood Roofing around full-cycle capability, so the same crew that inspects your roof is the one that replaces it.
South Whittier’s unincorporated status means county permitting, not city. We handle that process weekly for homeowners across 90605, so we know what the county wants to see on wind-load documentation and final inspection day. That’s local knowledge you don’t get from a roofing company based forty miles away.
Styles & brands we work with
Asphalt Shingle Roof Replacement in South Whittier
Asphalt Shingle Roof Replacement in South Whittier means more than swapping shingles. On the low-slope tract homes built here in the 1950s and 60s, the original 3-tab shingles were often installed right at the manufacturer’s minimum slope, sometimes below it, without the membrane underlayment modern code requires. We tear off to the deck, check for rot and failed flashing, then install a system that actually matches the pitch.
A full asphalt shingle replacement on a standard South Whittier ranch runs $11,000 to $16,000 depending on square footage and whether the decking needs patching. Architectural shingles add $1,500 to $3,000 over 3-tab. You get more years, better wind resistance, and a cleaner look on those low-slung stucco exteriors.
What We Check Before Replacing Shingles
We look at the slope, the underlayment condition, the flashing at every penetration, and whether the attic ventilation can handle inland SoCal heat. A roof that’s overheating from the inside will cook new shingles from below, shortening their life. We fix the system, not just the surface.
Decking Replacement on South Whittier Homes
Roof decking replacement is often necessary on 1950s-60s homes where original plywood or skip sheathing has water damage around failed flashing. We’ll quote the decking work separately so you see exactly what you’re paying for, per sheet. No lump sum that hides surprise change orders later.
New Roof Installation in South Whittier
New Roof Installation in South Whittier often means a flat or low-slope membrane system, not shingle work. The post-war bungalows and small ranch homes here lean flat, with built-up roofs that have been baking under inland sun for decades. When they go, they go in stages: hairline membrane cracks, then ponding, then a ceiling stain after the first big December rain.
A new flat roof membrane for a typical South Whittier home runs $9,000 to $14,000 before any structural correction. If we’re adding a cricket to fix ponding or replacing rotted decking at a carport tie-in, that pushes the number up. We’ll show you the line items.
Flat and Low-Slope Membrane Systems
We install SBS-modified membranes like GAF Liberty and comparable systems from IKO and Tamko. The key is installation quality: proper overlap, correct adhesive coverage at seams, and drainage that actually drains. Most flat roof failures we see in South Whittier aren’t material failures. They’re installation failures from decades ago.
Why County Wind-Load Documentation Matters
LA County Public Works requires wind-load documentation for roof replacements on these low-slope tract homes. A compliant quote includes the engineering letter and the specific product ratings. A cheap quote often leaves that out, and you find out at inspection time when the county stops the job.
Trusted Brands We Service in South Whittier
We work with seven manufacturer lines, including IKO, Atlas, and Tamko, so the recommendation you get from us is the product that fits your South Whittier roof, not whatever one brand we happen to be tied to. For flat and low-slope systems we lean on GAF and CertainTeed membranes rated for the wind loads the county requires. For shingle roofs, we’ll show you apples-to-apples comparisons across three or four brands at your price point. Seven brands, one honest recommendation.
Common Roof Replacement Problems We See in South Whittier Homes
- Ponding at rear additions and carport tie-ins: The original flashing on these 1950s-60s additions pulls away over decades, and water finds the gap. By the time you see a ceiling stain, the decking underneath is usually already compromised.
- Shingle blow-off on low-slope installations: 3-tab shingles installed at or below minimum slope without proper membrane underlayment lift in Santa Ana wind events. We see this on streets throughout 90605 every year after the first big blow.
- Premature membrane cracking on flat roofs: Inland UV bakes exposed built-up roofs and torch-down membranes until they fissure. Without reflective coating or adequate ventilation, the heat cycle just accelerates the cracking.
- Failed flashing at converted garage and addition rooflines: South Whittier has a lot of converted garages and lean-to additions, and the flashing at those tie-ins was rarely done to modern standard. That’s a recurring leak point we correct on nearly every tear-off.

FAQs About Roof Replacement in South Whittier
LA County Public Works requires wind-load documentation showing the roof system meets the design wind speed for the area, typically in the 85 to 95 mph range for Exposure B sites in South Whittier. Your permit package needs the engineering letter and product data sheets. We include this documentation with every South Whittier roof replacement permit application, so there’s no stop-work order waiting on paperwork. Call (855) 382-1073 and we’ll explain exactly what your specific roof requires.
Yes. South Whittier is unincorporated LA County, so permits go through LA County Public Works, not a city building department. Same permit, different counter. We pull the permit, schedule the inspections, and make sure the final sign-off happens before you pay the final invoice. Working without one creates a problem whenever you sell the house or file an insurance claim.
Documented compliance is your proof in a claim. If wind damages a shingle roof that was installed with county-approved wind-load documentation, the insurer has a clear record that the roof met code at installation. That makes claims faster and reduces the chance of denial based on “pre-existing condition” arguments. If a cheap roofer skips the documentation, you’re fighting your own insurer from day one. We give you the paperwork with the roof.
A square is 100 square feet of roof area. Every quote you’ll see from any roofer, including ours, prices material and labor per square. South Whittier homes typically run between 14 and 22 squares. Knowing your square count lets you compare quotes honestly, apples to apples. We’ll show you the square count on your estimate so you can verify what you’re paying for. Call (855) 382-1073 for a measured quote, not a guess.
We correct it structurally, not cosmetically. Ponding means the drainage isn’t working. On a 1958 flat-roof bungalow off Lambert Road, our crew found the rear addition ponding because the original flashing had pulled away from the carport tie-in. We tore off the old built-up roof, installed a GAF Liberty SBS membrane with a 2-inch overlap and new ice and water shield at the low spots, then added a cricket to divert water to the existing drain. The homeowner had a dry ceiling through the first December rain and passed the county inspection without a single correction. That’s how you fix ponding: give the water somewhere to go.
