We know Florence-Graham’s streets, its alleys, its tight lots, and its aging roofs. Our crews work along Compton Avenue, Hooper Avenue, and the side streets between Firestone Boulevard and Florence Avenue every month. When you call, a real person answers. When we show up, the technician’s name and photo arrive on your phone first, and they badge in with a photo ID at the door. That’s how we work here.
Why Mercer Roofing Co Torrance Is Florence-Graham’s Preferred Roof Installation Company
Founded in 2000 and part of the Threshold Group family, Mercer Roofing has built its Florence-Graham reputation one roof at a time. Homeowners here deal with a specific set of problems: layered shingles, hidden wood shake, party walls, low-slope rear additions, and county permit rules that trip up out-of-town crews. We deal with those problems every week.
Every Mercer technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard. That means a clean, marked uniform and a photo ID badge at your door, every time. Grant Whitlock leads our team, and he holds every job to one standard: a written price before any work starts, and a written 365-Day Done Right Promise on every repair and install. If it’s not right within a year, we make it right.
We answer the phone 24/7. Not a voicemail, not a callback form. A live person. When a Florence-Graham homeowner calls about a leak on a Sunday evening, they get a human voice and a plan, not a machine.
Styles & brands we work with
Tile Roof in Florence-Graham
Tile Roof installation in Florence-Graham is the most common upgrade we quote for the area’s 1920s to 1960s bungalows, especially where investors and rental property owners want a low-maintenance roof that survives the inland sun without warping or curling. A standard tile roof on a Florence-Graham single-story home runs $14,000 to $22,000 depending on the tile profile, underlayment system, and what we find under the old roofing.
Tile handles Florence-Graham’s UV exposure better than asphalt, but only if the underlayment is right. Semi-arid heat degrades cheap underlayment in a decade. We install reinforced synthetic underlayment under every tile roof we put on in this area.
Concrete and Clay Tile Systems
We install concrete tile for homeowners who want a 40-to-50-year roof without clay’s price tag, and clay tile when the home’s architecture calls for it. Both require a structural check first. Some Florence-Graham homes were never framed for the extra weight, and we inspect the rafters and decking before we quote.
Santa Ana Wind and Tile Uplift
Florence-Graham sits in a wind path that catches Santa Ana gusts. Loose or cracked tiles become projectiles. We use mechanical fastening on the perimeter courses and around hips and ridges, and we inspect field tiles for thermal movement cracks that let water reach the decking.
Roof Ventilation in Florence-Graham
Roof Ventilation in Florence-Graham is the quiet fix that extends the life of every roof we install. Attic temperatures here hit 130 degrees and higher in July and August, which bakes shingles from underneath and shortens their life by years. A properly vented roof on a Florence-Graham home costs $450 to $1,800 depending on the system, and we handle it during every install.
Most older Florence-Graham bungalows have one or two box vents and not much else. That’s not enough for a home with a low-slope rear addition and a south-facing gable. We calculate intake and exhaust balance and size the ventilation to the attic’s actual cubic footage.
Intake and Exhaust Balance
You need air coming in low (soffit vents or edge vents) and air going out high (ridge vents, turbines, or powered fans). Skip the intake and the exhaust vents pull from the living space instead. That raises cooling bills and pulls conditioned air out of the house.
Flat Roof and Low-Slope Venting
Florence-Graham’s flat rear additions trap heat differently than a pitched gable. We often install low-profile powered vents or cross-vented soffit-to-ridge paths on these sections, because a hot flat roof cooks the built-up roofing membrane from below and cracks the seams faster.
Trusted Brands We Service in Florence-Graham
We install and repair roofs using manufacturer-recognized shingle and tile brands, including GAF and Owens Corning for asphalt systems, and IKO and Atlas where the job calls for a specific profile. For tile, we work with Boral concrete and clay tile. We keep common flashing profiles, underlayment rolls, and ridge cap stock staged for Florence-Graham jobs, which means we don’t lose days waiting on materials from a distributor across town. When you call about a full replacement, we can usually start the permitting process the same week.
Common Roof Installation Problems We See in Florence-Graham Homes
- Layered composition over original wood shake. Many homes along Compton Avenue and nearby streets still carry two or three layers of composition shingles over the original 1930s wood shake. Tearing that off often exposes decking rot that changes the scope, the permit, and the price. We quote for what we can verify, and we explain what we might find before the tear-off starts.
- Improper flashing at shared walls. Florence-Graham homes sit close, and some share party walls with inches of clearance. Handymen skip step flashing or reuse old metal, and the first winter rain leaks into both units. We cut new step flashing, inspect the shared wall sheathing, and notify the adjacent property manager before opening anything.
- Low-slope built-up roofs with failed seams. Flat rear additions fail at the seams after heavy winter downpours, and years of tar patchwork traps moisture against the plywood. We remove the old built-up roof, check the decking, and install a proper membrane system with positive drainage.
- Tile roofs with weak underlayment. Tile systems installed over old or missing underlayment crack under Santa Ana uplift and thermal expansion. The tile looks fine from the street, but the underlayment below it is shot. We always inspect what’s under the tile, not just what’s on top.

Three things move the price in Florence-Graham more than anything else: how many layers we’re tearing off, what we find under them, and whether the lot gives us a place to stage materials or forces a portable dump trailer in the alley. We give you a written price before any work starts, and that price doesn’t change unless we find something structural that requires a permit amendment, which we document and explain before touching it. Call (424) 435-5428 for a free estimate.
How We Work on Florence-Graham’s Tight Lots
Florence-Graham’s pre-1960 bungalows sit on compact lots with narrow driveways, shared side yards, and alley access. A roof replacement here is not the same job as a suburban cul-de-sac reroof. Staging matters. We stage materials on the driveway when we can, use a portable dump trailer in the alley when we can’t, and keep the shared side yard clear. If we’re working on a home with a shared wall, we notify the adjacent property manager before opening the party wall for new step flashing. Access affects the quote, and we walk every Florence-Graham job before we price it. Read more about our Roof Installation approach and what to expect.
On a 1950s bungalow off Compton Avenue, our crew stripped back three layers of composition to find the original wood shake roof so rotted that half the decking had to be replaced before we could lay down GAF underlayment and architectural shingles. We staged materials on the narrow driveway and used a portable dump trailer parked in the alley, keeping the shared side yard clear and notifying the adjacent rental’s property manager before we opened the party wall for new step flashing. That’s the job: solve the roof, respect the neighbors, and leave the site clean.

FAQs About Roof Installation in Florence-Graham
Yes. Los Angeles County requires a reroofing permit even for like-for-like shingle replacement in Florence-Graham. If your home has layered composition over original wood shake, the tear-off count changes the permit scope. Call (424) 435-5428 and we’ll explain what applies to your specific house before you file anything.
We use the driveway, the alley, or a portable dump trailer as the situation allows. We never block a neighbor’s access or park materials across a shared walkway. We walk the lot before quoting and make the access plan part of the written estimate.
Many Florence-Graham homes built between the 1920s and 1950s still have their original wood shake roofs under two or three layers of composition shingles. The shake is often rotted, and the decking under it needs replacement before new roofing goes on. We quote for what’s visible and document what we find at tear-off.
If your home shares a party wall in Florence-Graham, yes, we recommend notifying the adjacent property owner or manager before we open the shared wall for flashing work. We make that call ourselves when you give us the property manager’s contact. It prevents disputes and keeps the job moving.
We need enough room to stage tile pallets and a dump trailer. On a typical Florence-Graham lot, that means the driveway plus alley access, or curbside permission for a short staging window. If access is too tight for tile, we’ll tell you before you spend on it, not after.
