Fast, Reliable Roofing Company Across Compton
Roofing work in Compton costs more than most homeowners expect, and the reason is written right into the streets: nearly every block in this city was built between 1948 and 1965, which means roofs are failing in waves, not one at a time. Our Roofing Company team replaces and repairs those roofs every week, and we scope each job for what’s actually up there before we ever hand you a price. If you live off Alondra, Rosecrans, or Long Beach Boulevard, you already know what a Compton roof looks like after 60 years of sun and Santa Anas. Call (743) 200-8347 and we’ll walk you through what your roof actually needs, in plain English, before you spend a dollar.
Why Mercer Roofing Is Compton’s Preferred Roofing Company
Before we send anyone to your home in Compton, you get their name and photo ahead of time. That’s non-negotiable for us, and it matters in a city where homeowners tell us they’ve had too many strangers knock unannounced. Every Mercer technician is background-checked, identity-verified, and arrives at your door wearing a clean uniform and a photo ID badge, presented before they step inside. We call this the Threshold Standard, and each independent Mercer location, including the crews serving Compton, is held to it contractually. You’ll know who’s on your property before they ring the bell.
Grant Whitlock leads Mercer Roofing, and the company has been part of the Threshold Group family since 2000. Compton homeowners call us because the warranty language is specific, not vague: every repair carries a written guarantee, and if that repair fails within 365 days, we return and make it right, including a free second visit. There’s a name behind the work, a written price before the first nail, and a phone number answered by a living person, 24/7.
Commercial Roofing in Compton
Commercial Roofing in Compton means working with the same postwar building stock, but on a different scale: small retail strips along Compton Boulevard, warehouses and auto shops on the east side near the 710, and multi-unit buildings that were never re-roofed since the 1960s and 70s. A typical commercial tear-off and replacement in Compton runs $7,500 to $18,000 depending on square footage and decking condition, while commercial repairs and coatings typically land between $950 and $4,200. Most commercial roofs here are low-slope built-up or modified bitumen systems, and many have been patched so many times the original surface is unrecognizable.
Low-Slope Commercial Systems
On flat and low-slope commercial roofs in Compton, we install modified bitumen and TPO-style systems rated for the UV load this city dishes out. The real cost driver is what’s underneath: older Compton commercial buildings often have water-damaged insulation board or rotted wood decking that only shows up once the old roof is off. We scope it before quoting, and the written price reflects what we find.
Preventative Maintenance Plans
For commercial property owners along Artesia Boulevard or in the industrial pockets near Alameda Street, small leaks become big ones fast when Santa Ana winds peel back existing patches. We offer annual inspection and maintenance agreements that catch edge lifting, failed sealant, and blistering before a full replacement becomes the only option.
Metal Roof Installation in Compton
Metal Roof Installation in Compton works well on the small ranch and bungalow roofs that dominate this city, because standing-seam and corrugated metal panels can handle the long UV season and won’t lift the way dried-out three-tab shingles do when the winds hit. A metal roof on a typical 900 to 1,200 square foot Compton home runs $14,000 to $28,000, and on small commercial buildings the range is $18,000 to $42,000 depending on panel profile, fastening system, and whether we can install over the existing roof or have to tear off first.
Standing Seam Upgrades
Homeowners on streets near Gonzales Park and Richland Farms often ask whether metal is worth the premium over architectural shingles. On a shallow-pitch Compton roof, the answer is usually yes if you plan to stay in the house: a mechanically seamed standing-seam panel doesn’t rely on adhesive strips that UV degrades, and it gives you a 2:12 or 3:12 pitch a far longer service life.
Retrofit Over Existing Shingles
We can often install metal over a single layer of existing shingles, which saves on dumpster and labor costs. But on Compton homes where two or three layers are stacked from decades of patch jobs, we’ll need a full tear-off first. That changes the price meaningfully, so we show you both options in writing before any work starts.
Trusted Brands We Service in Compton
We install and repair roofing systems from GAF, Atlas, and Tamko, and we keep the most common profiles for Compton homes stocked locally so replacements don’t wait on a distributor run from across the county. Whether you need a full architectural shingle field in a specific color for a Richland Farms property or a specific Tamko modified bitumen roll for a flat-roof commercial repair near the Compton Airport, we can pull it fast. We won’t push a brand that doesn’t fit your roof’s pitch and exposure; we’ll tell you what works and what won’t on a 2:12 Compton roof, then put that choice in writing.
Common Roofing Company Problems We See in Compton Homes
- Stacked shingle layers from decades of patch-repair: Tear-offs on Compton ranches routinely reveal two or three layers of old three-tab shingles, which doubles dumpster loads and exposes failed felt underneath. Homeowners are often surprised by the square count change, but it’s the single biggest driver of cost differences between Compton and neighboring cities.
- Low-slope pitch failures during Santa Ana events: At a 2:12 to 3:12 pitch, aged shingles have almost no mechanical interlock once the sealant strip dries out. When the winds come down the San Gabriel Mountains, whole fields of shingles roll back like carpet on these homes, a failure mode we rarely see on steeper pitches in Cerritos or Torrance.
- UV-dried plank and early-plywood sheathing: Sixty or more years of inland LA sun dries out the original decking until it delaminates and splits. Fasteners won’t seat into that surface, and underlayment telegraphs through, so we end up replacing sheathing on a large share of Compton tear-offs.
- Failed felt and ice-and-water shield gaps: Compton gets about 13 inches of rain a year, but it arrives in a short winter window. Roofs that look fine all summer fail all at once during the first real storm, and the underlying felt is often the culprit because it was never properly lapped or was reused during earlier patch jobs.
Pricing for Roofing Company in Compton, CA
Roof repair in Compton typically runs $450 to $1,800 for isolated leak fixes, flashing replacement, or shingle repair, while a full tear-off and architectural shingle replacement on a 900 to 1,200 square foot ranch home runs $9,500 to $16,500. If we find multiple shingle layers, rotted plank decking, or a failed low-slope underlayment system, that range adjusts upward; we document every discovery with photos and a line-item change before proceeding.

FAQs About Roofing Company in Compton
Compton roofs cost more because the city’s ranch tracts were built in a concentrated burst from the late 1940s through the mid-1960s, so nearly every home in a given neighborhood hits end-of-life at once and has been patched, not replaced, for decades. That means tear-offs routinely uncover multiple shingle layers, failed felt, and rotted plank decking that must be replaced before new roofing goes on. Call (743) 200-8347 and we’ll scope your roof specifically before quoting.
Yes, it does. Most Compton ranch homes sit at a 2:12 to 3:12 pitch, which is at or below the minimum for standard three-tab shingles, so we upgrade to architectural shingles with enhanced underlayment or switch to a low-slope modified bitumen system. Installing standard three-tab on that pitch is exactly how we see whole shingle fields fail during Santa Ana wind events. A written quote will specify the right material for your pitch.
We address Santa Ana wind risk by specifying architectural shingles with a reinforced starter strip, six-nail fastening patterns where the manufacturer allows, and properly lapped ice-and-water shield across the eaves and low-slope field. We also replace drip edge and check that the decking can actually hold fasteners before we start. On a 2:12 roof, the details at the edges and starter course make the difference between a roof that holds and one that peels back.
A roofing square is 100 square feet of roof area, and most Compton homes are between 9 and 14 squares. Your quote is driven by the number of squares, plus what we find when we tear off: hidden shingle layers, rotten sheathing, and failed felt all add square count and labor to the final written price. We walk you through the measurements on site so you see the math for yourself.
Yes, we install standing-seam and corrugated metal systems on both homes and small commercial buildings throughout Compton, including low-slope applications where metal often outperforms shingles long term. A typical Compton home metal roof runs $14,000 to $28,000, and we’ll show you panel profiles and fastening options in writing before you commit. Call (743) 200-8347 for a free estimate on metal roofing.
