Why Gable Roof Repair Is Commerce’s Preferred Roof Replacement Company
Homeowners in Commerce call us because we show up, climb the roof, and tell you what we actually found. That’s the whole model. Neil Drummond started Gable Roof Repair around a repair-first philosophy, and it holds on every replacement job we quote. If a roof can be repaired safely and honestly, we’ll say so. When replacement is the right call, we’ll explain why with photos, measurements, and specific pricing.
We know the housing stock here: post-WWII stucco tract homes with low-slope or shallow-pitch roofs, plus a heavy share of flat-roofed warehouses and machine shops tied to the rail and freight economy. That split means our crews understand both steep-slope shingle systems and TPO or modified-bitumen flat roofing. We don’t hand residential work to one crew and commercial to another and pretend it’s seamless. The same foreman who checks your neighbor’s shingle roof near Commerce Way can assess a flat roof off Slauson Avenue.
Response time matters. Commerce is minutes from our Los Angeles County service routes, and we typically schedule initial inspections within a few business days. For a roof that’s actively leaking after one of those rare winter downpours, we prioritize you. Call (866) 650-8319 and we’ll get someone out to look.
Roof Installation in Commerce
Roof installation in Commerce is not a one-size job. The 1950s-70s tract homes scattered through the residential pockets off Eastern Avenue and near Bandini Park have shallow-pitch roofs that bake under inland Los Angeles Basin sun. When we install a new roof on those homes, we’re tearing off heat-aged asphalt shingles, inspecting the decking, replacing rotted or soft plywood, and laying new underlayment before the shingles go down. A full tear-off and new installation on a 1,200-square-foot Commerce home typically runs $11,000 to $19,000 for architectural shingles.
Working With Seven Brands, Not One
We’re certified to install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral shingles. That matters because your roof’s slope, exposure, and budget should dictate the product, not a single-brand sales agreement. If a homeowner off Atlantic Boulevard wants IKO’s Cambridge line because it matches the neighbor’s roof and carries a strong warranty, we install it correctly. If a warehouse off 710 wants Tamko’s commercial TPO, we know the heat-welding requirements.
Permits and Paperwork Handled
Roof replacement in Commerce requires a permit through the city’s Building and Safety Division, and the permit process is where surprises surface. When walls are open or decking is exposed, inspectors may flag undersized rafter spacing or outdated wiring. We handle the permit application, schedule inspections, and price any code-driven upgrades in writing before we start. No verbal handshakes on scope changes.
Roof Replacement Contractor in Commerce
A roof replacement contractor in Commerce has to understand that most local homes weren’t built for modern roofing systems. The original shake or three-tab shingles on a 1960s tract home near Bristow Park went over spaced board sheathing, not plywood. When we replace those roofs, the decking often needs to be overlaid or replaced entirely. A full replacement including new plywood decking on a 1,500-square-foot Commerce home lands between $16,000 and $24,000, depending on framing repairs and access.
What a Full Tear-Off Involves Here
We recently replaced a low-slope roof on a 1960s stucco tract home near Bristow Park. The original decking was soft around the pipe penetrations, and the fascia had dry rot from decades of heat cycling. After tearing off the old shingles, we found outdated wiring running through the attic that had to be rerouted before we could install new underlayment and ice and water shield in the valleys. Neil Drummond’s crew priced the additional framing and electrical work in writing, got approval, and finished with GAF architectural shingles and a ridge vent. That sequence, inspection first, allowances written in, change orders approved before work proceeds, is how we handle every Commerce replacement.
Flat Roof Replacement for Commerce’s Commercial Stock
Commerce has more flat-roofed light-industrial buildings per square mile than almost any city in Los Angeles County. Warehouses, machine shops, and truck yards along the 5/710 corridor rely on TPO or modified-bitumen membranes that get hammered by UV and diesel soot. A flat commercial re-roof in Commerce typically runs $18,000 to $45,000 depending on square footage, insulation requirements, and drain replacement. We tear off the failed membrane, inspect the underlying structure, repair or replace deteriorated decking, and install a new fully adhered system.
Trusted Brands We Service in Commerce
We stock and install roofing materials from seven major manufacturers, and that matters in Commerce because roof types vary so sharply from street to street. Atlas and IKO architectural shingles hold up well on the shallow-pitch tract homes that dominate the residential blocks. Boral’s tile and stone-coated systems make sense for some of the newer or custom homes near Bristow Park. On the commercial side, Tamko’s TPO and modified-bitumen lines handle flat warehouse roofs. We don’t push a brand. We spec the material that fits your roof’s structure, slope, and exposure, then install it to the manufacturer’s exact requirements. Your roof’s job is to protect everything underneath it, and the material choice has to serve that job.

AfterCommon Roof Replacement Problems We See in Commerce Homes
- Heat-aged shingle failure: Inland Basin sun bakes roofs year-round. By the time a Commerce homeowner sees curling or granule loss, the shingles have usually lost most of their flexibility, and the underlayment beneath them is often cracked or deteriorating too.
- Diesel soot clogging flat-roof drains: Constant truck and rail traffic settles a fine black grit on roofs. It washes toward drains and scuppers, clogs them, and causes ponding that accelerates membrane failure. This is a Commerce-specific problem that inland homeowners a few miles away never deal with.
- Undersized framing in 1950s-70s tract homes: Original rafter spacing was often built to minimum code from 60 years ago. When we open the ceiling or decking, inspectors may require structural upgrades before new roofing materials go on.
- Failed waterproofing at penetrations: Pipe boots, vents, and skylight curbs break down from UV exposure. We routinely find soft decking and water staining around these spots on Commerce homes, even when the shingles themselves look salvageable.

FAQs About Roof Replacement in Commerce
Diesel soot and road grit settle on flat roofs and wash into drains and scuppers with any rain or dew. Over months, that accumulation clogs the drainage system and causes ponding, which breaks down TPO or modified-bitumen membranes far faster than UV alone. If you have a flat roof in Commerce, schedule drain cleaning and inspection at least twice a year. Call (866) 650-8319 and we’ll add you to our maintenance rotation.
Soft or rotted plywood decking around penetrations, undersized rafters that no longer meet code, and outdated wiring running through the attic are the three most common surprises. We build allowances into every replacement quote for these possibilities, and we price any discovered damage in writing before we proceed. You’ll never get a surprise invoice.
Yes, Commerce requires a building permit for roof replacement work. The inspection process can trigger code upgrades if the inspector finds undersized framing, degraded sheathing, or electrical work that doesn’t meet current standards. We handle permits, schedule inspections, and give you a written change order for any required work before we touch it.
We spec materials that hold up under prolonged inland heat: Atlas and IKO architectural shingles with high UV resistance for steep-slope sections, and fully adhered TPO or modified-bitumen for flat areas. We also install ridge and eave ventilation where the original home had none, because attic heat is what cooks shingles from underneath and shortens roof life. The material choice and ventilation plan are part of every quote we write.
Ask for the exact square count and the waste factor. A square is 100 square feet. A 1,500-square-foot home with a 4/12 pitch might actually have 18 to 22 squares of roof surface once you include overhangs and hips. If a contractor quotes by the square without telling you the count, push for it. Our quotes show square count, material type, and waste factor line by line. Call (866) 650-8319 for an estimate you can actually read.
