Why Mercer Roofing Co Los Angeles Is North Hollywood’s Preferred Roof Installation Company
We’ve spent years on roofs across North Hollywood, and the housing stock here tells a story. The 1950s ranch homes and 1920s bungalows that line streets near Magnolia Boulevard and Lankershim weren’t built with the San Fernando Valley’s UV load in mind. Their original roofs are aging out, and homeowners want a company that understands exactly what they’re looking at before they sign anything.
That’s why our process starts with a written price. Not a ballpark, not a verbal “we’ll figure it out later.” A line-item, written quote for the full scope of work, delivered before the first nail gets driven. If the project changes, the price doesn’t change with it unless you approve a written change order first.
Mercer Roofing was founded in 2000 and operates as part of the Threshold Group family of home-service companies. Each location is independently owned and operated, and every technician is held to the Threshold Verified standard: background-checked, identity-verified, and badged. When we schedule your roof installation in North Hollywood, you’ll know exactly who is coming. That’s not a nice-to-have. For homeowners who are often alone or have young kids at home, it’s the whole point.
Styles & brands we work with






Shingle Roof in North Hollywood
Shingle roof installation in North Hollywood means tearing off the old composition shingles on your ranch or bungalow, inspecting the decking beneath, and laying down new underlayment and architectural shingles rated for the Valley’s heat. Most homes here were built between the 1920s and 1960s, and many still have their original shingle layers deteriorating under 90°F-plus summer sun. Granule loss, curling at the edges, and cracking are the signs we see most often.
A full shingle roof replacement in North Hollywood typically runs $9,800 – $16,200 for a single-family home under 2,000 square feet. Homes with steeper pitches, multiple roof planes, or rotted decking sections will land toward the higher end. We work with GAF, CertainTeed, and Owens Corning architectural shingles, and we can walk you through the wind ratings and color lines that hold up best on North Hollywood streets where afternoon sun exposure is relentless.
Decking and Ventilation Checks Before Shingle Install
Before we lay a single shingle, we check decking integrity and attic airflow. Ranch homes in North Hollywood often lack ridge vents, which means trapped heat bakes the underside of the roof and shortens shingle life. We’ll tell you if your existing ventilation is inadequate and include the fix in the written quote. You won’t get a surprise call about decking rot after the tear-off because we scope it before we start.
Our Preferred Shingle Brands for Valley Heat
North Hollywood summers sit above 90°F for weeks at a time. That’s why we lean toward architectural shingles from GAF and CertainTeed with higher solar reflectance ratings. They don’t just last longer under UV load; they keep your attic cooler and reduce strain on your AC. We’ll show you spec sheets, not just samples.
Standing Seam Metal Roof in North Hollywood
Standing seam metal roof installation in North Hollywood is an increasingly common choice for homeowners who want a roof that won’t fail the way torch-down and composition shingles do here. The heat in the eastern Arts District and around Valley Glen accelerates damage on asphalt-based systems, but standing seam metal carries a 30- to 50-year lifespan in this climate when installed correctly. The panels reflect UV rather than absorbing it, and seams are raised above the water line so wind-driven rain doesn’t wick into the roof.
Expect to pay $18,000 – $28,500 for standing seam metal on a typical North Hollywood ranch home, depending on roof square footage, panel gauge, and whether you choose Kynar-coated finishes. It’s a bigger upfront investment than shingles, but for homeowners planning to stay in the home for 15-plus years, it often ends up cheaper per year than replacing an asphalt roof twice in that same window.
What We Use on Valley Homes
For North Hollywood installations, we recommend 24-gauge steel panels with a Kynar 500 finish. That coating holds up against years of direct sun without chalking or fading the way thinner coatings do. We also install a high-temperature underlayment beneath the panels to protect the decking from both rain and radiated heat.
When Metal Makes Sense Over a Low-Slope Ranch
If your home has a low-slope roof of 2:12 pitch or less, we’ll talk through what standing seam can and can’t do. Some older North Hollywood ranch roofs are too shallow for exposed-fastener metal, and we’ll tell you that honestly. Where metal works, it changes the calculus on maintenance: no granule loss, no alligatoring, no torch-down patch cycles every few years.
Trusted Brands We Service in North Hollywood
We install and repair roofs using manufacturer-recognized shingle and metal brands, including GAF, Atlas, and Boral systems. For North Hollywood homeowners, we keep common flashing profiles, ridge caps, and underlayment rolls stocked locally so we’re not waiting on a warehouse shipment when your roof is torn off and the weather window closes. If you have a preference for a specific brand, tell us during the estimate and we’ll spec the job around it. Our written quote always names the exact products we’ll use, not just “comparable materials.”

AfterCommon Roof Installation Problems We See in North Hollywood Homes
After years of roofing in this area, certain failure modes show up again and again. Here’s what we watch for:
- Alligatoring on 1950s – 60s torch-down roofs: The eastern Arts District still has original torch-down layers that buckle and crack in July heat waves, creating alligator-skin patterns. These split along seams and let water reach the decking at the first winter storm.
- Granule loss and cracking on low-slope ranch roofs: Original composition shingles on Minimal Traditional homes lose granules prematurely under Valley UV, exposing the underlayment. Leaks often appear around swamp cooler mounts and plumbing vents first.
- No drip edge and minimal overhangs: Older bungalows in North Hollywood were built with narrow eave lines. Without drip edge, wind-driven rain wicks under the starter strip and rots the fascia boards. We see this frequently on homes near Tujunga Avenue and the blocks west of the 170 Freeway.
- Spongy decking from decades of trapped heat: On a 1958 ranch in the Arts District, one of our techs lifted a curling torch-down layer and found the original decking soft from trapped heat and winter seepage. We stripped to the joists, replaced the decking, and laid ice and water shield at the eaves before installing a new GAF built-up system with a white reflective cap sheet. That roof is now rated for Valley UV load and the occasional heavy rain event, but the underlying damage never would have been caught without a full tear-off.

FAQs About Roof Installation in North Hollywood
Yes, a roof replacement on a single-family home in North Hollywood requires a permit through the Los Angeles Department of Building and Safety. The permit is pulled by the contractor, not the homeowner, and it covers the structural scope: tear-off, underlayment, and the new roof system. We pull permits on every installation and schedule inspections when the work is complete. Call (213) 521-8272 and we’ll walk you through what your specific home needs before you commit to anything.
Detached garages, workshops, and ADUs add square footage to the project and are often roofed with different materials than the main house. In North Hollywood, many older lots have detached garages with the same failing torch-down or composition shingle roofs as the main structure. Each structure gets its own scope line in our written quote, so you don’t pay a blended price that hides what each roof actually costs. We include all structures in the free estimate; you’ll see a breakdown, not a bundle.
Heat waves above 90°F accelerate granule loss on asphalt shingles and cause torch-down membranes to alligator, so material choice here isn’t cosmetic. Architectural shingles from GAF or CertainTeed with high solar reflectance are the practical upgrade for budget-conscious homeowners. Standing seam metal costs more upfront but won’t crack, buckle, or lose granules. We’ll show you the comparative cost per year of each option based on your home’s specific sun exposure, then let you choose without pressure.
Alligatoring means the torch-down membrane has dried out from Valley heat and started cracking in a pattern that looks like reptile skin. If you can see those cracks running along seams or around roof penetrations, the membrane can no longer keep water out during winter rains. Urgent replacement is indicated when you also notice blistering, exposed felts, or water stains on interior ceilings. If you’re in the Arts District and see these signs, call (213) 521-8272 for an estimate on replacement before the first storm hits.
Yes, Los Angeles County and the city of Los Angeles require shingle fasteners to meet manufacturer specifications, which for architectural shingles typically means six nails per shingle in high-wind zones and four nails in standard zones. The exact pattern depends on the shingle brand and your home’s wind exposure rating. We follow the manufacturer’s printed installation instructions on every job, which is what inspectors verify. If you want to see the spec sheet for your chosen shingle, we’ll include it with your written quote.
