Fast, Reliable Roof Installation Across Maywood
A new roof in Maywood typically runs $9,800 to $18,500 for a full tear-off and architectural shingle install on the bungalows and small apartment buildings that fill this city. That price reflects something most Maywood homeowners discover early: your roof isn’t just a roof. It’s decades of layered shingles stacked on a 3-to-4-foot side yard that no dumpster can reach. We’ve worked those tight lots on Slauson, 41st Street, and throughout the 90270 ZIP long enough to know exactly how the job changes when you can’t roll equipment beside the house. Call (743) 200-8347 for a written, line-item estimate before any work starts.
Why Mercer Roofing Is Maywood’s Preferred Roof Installation Company
Maywood homeowners don’t ask us for a sales pitch. They ask two things: who is coming to my door, and exactly what will this cost. We answer both before the first nail is driven. Every technician’s name and photo is sent to you before the visit. When they arrive, they carry a photo ID badge and wear a clean, marked uniform. That’s the Threshold Verified standard each Mercer Roofing location is held to, and it’s built for the person home alone with young kids or a parent who wants proof at the door.
Local reviews from Maywood customers consistently point to the same thing: the written price held. No change orders slipped in. No “we found more damage once we opened it up” phone call with a vague new number. Maywood’s housing stock hides surprises, and we tell you that upfront. What we also tell you is that when those surprises appear, we price them in writing and get your approval before we touch anything. Crews are dispatched from the brand’s Los Angeles office, so we’re close when you need us, and response time to Maywood is usually within one to two business days for the written estimate.
Roof Ventilation in Maywood
Roof Ventilation in Maywood matters more than in most of the Los Angeles Basin because of how tightly the homes sit and how long the sun beats on them. A poorly vented roof on a 1940s bungalow off King Avenue traps heat in the attic, cooking the underside of your shingles and shortening their life even when the top looks fine. Proper intake and exhaust airflow – usually soffit vents combined with a ridge vent – pulls that hot air out before it bakes your decking.
What we check first
We look at the existing soffits, the attic access, and whether the roofline even has a ridge long enough for a continuous vent. Many Maywood homes have hip roofs with very short ridges, which means we adjust the system rather than forcing a product that won’t move air. We also check for bathrooms or kitchen fans venting into the attic, which is common in older Maywood homes and quietly rots the decking from below.
Typical Maywood cost
Roof ventilation upgrades on a Maywood re-roof run $450 to $1,300, depending on whether we’re adding ridge vent, soffit ventilation, or both. If the old roof is already off, the marginal cost drops because the crew is already on the roof. It’s the one upgrade we recommend on nearly every job here because Maywood summers above 90°F are brutal on trapped attic heat.
Roof Flashing Installation in Maywood
Roof Flashing Installation in Maywood is the difference between a roof that leaks next Santa Ana season and one that holds. Flashing is the metal that seals the joints where your roof meets a wall, a chimney, a skylight, or a valley. On Maywood’s low-pitch gable and hip roofs, valley flashing does a disproportionate share of the work because rain funnels hard into those shallow angles during the November-to-March rainy season. Failed flashing is often the first point of failure on a roof whose shingles still look acceptable.
Where we find failures
The usual suspects are the sidewall flashings where a bungalow addition meets the original roof, and the plumbing vent penetrations that haven’t been re-detailed since the roof was first installed. We strip the old flashing, inspect the wood beneath for rot, and set new step flashing and counter-flashing with proper sealant. This is not a patch job. It’s a re-detail of every penetration on the roof.
What flashing work costs here
On a Maywood re-roof, flashing is usually part of the full scope and priced into the estimate. If you’re doing a targeted flashing repair without a full roof, expect $650 to $1,800 depending on how many valleys, walls, and penetrations require re-flashing. We write the number down before we touch the roof, and it doesn’t change unless you approve a specific change in writing.
Trusted Brands We Service in Maywood
We install and service roofs using manufacturer-recognized shingle brands including GAF, Owens Corning, and CertainTeed. We also work with Atlas and Tamko when a specific line fits the project. For Maywood customers, that means you’re getting a shingle product with a real manufacturer’s warranty behind it, not a white-label knockoff. We keep common flashings, underlayment, and starter strips stocked for the Maywood area, which keeps turnaround tight when your estimate turns into a signed contract.
Common Roof Installation Problems We See in Maywood Homes
- Multi-layer shingle stacks: Decades of successive re-roofs mean many Maywood homes have three or even four layers of composition shingles stacked on the decking. LA County code requires full tear-off, not another overlay, and what’s underneath is often rotted decking and failed flashing nobody knew existed.
- 3-to-4-foot side yards: No dumpster trailer fits. No shingle conveyor reaches. Stripped shingles get hand-carried out through narrow gates or passed over shared fence lines, which adds real labor hours to every job. Any Maywood quote that doesn’t account for this is probably missing it.
- Santa Ana wind damage: The brittle, under-nailed shingles on Maywood’s 1920s-to-1950s bungalows lift first at the eaves and gable ends when the wind kicks up in the fall. What starts as a few lifted tabs quickly exposes the old drip edge and penetrations that were never re-detailed.
- Failing flat roofs on apartments: The small 2-to-4-unit buildings throughout Maywood often have flat built-up tar-and-gravel roofs running past their service life. The seams and flashings fail first, usually during the rainy season, long after the UV cracking and granule loss gave their warning.
Pricing for Roof Installation in Maywood, CA
A full tear-off and architectural shingle install on a Maywood bungalow runs $9,800 to $14,500. Larger homes or small apartment buildings run $14,000 to $18,500. The two biggest factors are roof size and access: a roof that can’t be reached by conveyor means hand-carry labor, and that’s often $1,200 to $2,500 of line-item cost on its own. Decking replacement, if rot is found after tear-off, runs $2.50 to $3.75 per square foot removed and replaced. We write every number down before work starts, and each line item has a fixed price.

FAQs About Roof Installation in Maywood
Because Maywood’s aging bungalows and small apartments hide rotted decking and failed flashing under multiple shingle layers, and LA County code requires full tear-off, not another overlay. The shingles themselves are a known cost. The decking and flashing underneath are only visible once the roof is open. At Mercer Roofing, we don’t treat that as a profit opportunity. We include a written allowance in the contract for likely decking replacement, and any additional work is priced in writing and approved by you before we touch it. Call (743) 200-8347 for an estimate that explains both the known and the likely.
Usually not. Maywood lots are among the tightest in California, with side yards commonly 3 to 4 feet wide. A standard dumpster trailer needs 8 to 10 feet of clearance, and a shingle conveyor needs a straight run from the truck to the roof edge. On most Maywood homes, stripped shingles are hand-carried through a narrow gate or passed over a shared fence line. We factor that labor into your quote honestly, so you’re not surprised later. It’s also why our Maywood estimates sometimes run higher than quotes you might see from a contractor who hasn’t visited the lot.
For Maywood’s low-pitch bungalow roofs, we recommend architectural asphalt shingles from GAF, CertainTeed, or Owens Corning with a full underlayment system including ice-and-water shield through the valleys. The shingles chosen should have a strong wind rating and UV resistance. Equally important is the installation itself: proper nailing pattern, starter strip, drip edge, and ridge vent. A premium shingle installed with the wrong nailing schedule will fail in the first big Santa Ana. Maywood’s heat demands ventilation, not just good shingles, and the valleys need real flashing re-detailing, not tar patches. For an exact system recommendation, call (743) 200-8347 and we’ll walk your roof with you.
Flat roof work on Maywood’s 2-to-4-unit apartment buildings involves a tear-off of the old built-up roof, inspection of the underlying substrate, and typically a modern membrane system such as modified bitumen or a single-ply membrane, depending on the building’s structure and drainage. The seams and flashings get the most attention, because that’s where Maywood’s rainy season finds the failures. Cost runs $9 to $14 per square foot depending on access and substrate condition. We’ll provide a written line-item quote before any work begins. Call (743) 200-8347 to schedule a free estimate.
Line them up by scope, not just by bottom line. Both quotes should state the number of shingle layers being removed, the underlayment system, the flashing scope, the ventilation changes, the decking allowance, and the permit fees. A Maywood bid that skips the tear-off logistics or skips the decking allowance will undercut a real quote by thousands and then come back later with a change order. Ask each contractor to show you the written allowance for decking replacement and the fixed price for hand-carry labor. Our quote includes both, and it’s yours to keep. Call (743) 200-8347 for a free, written, line-by-line estimate.
