AfterFast, Reliable Roof Installation Across North Hollywood
A full roof installation in North Hollywood typically runs $11,500 – $22,000 for a standard single-family home, with most jobs completed in 3 – 6 working days once the permit clears. The single biggest variable here isn’t the shingle you pick; it’s what’s hiding under the old roof and how tight the site access is off streets like Lankershim, Cahuenga, or Vineland. Our Roof Installation team has torn off enough North Hollywood roofs to know that behind the third layer of patch work, there’s usually a structural question waiting. Call (743) 200-8347 and we’ll put a real number on your roof, in writing, before any material gets ordered.
Why Mercer Roofing Is North Hollywood’s Preferred Roof Installation Company
North Hollywood homeowners keep our number close for one reason that has nothing to do with shingle brands: they know exactly who is walking onto their property. Every Mercer Roofing technician is background-checked and identity-verified under the Threshold Verified standard, and every one of them arrives in a clean, marked uniform with a photo ID badge. Before the visit, you get the technician’s name and photo sent to you. That matters on a street where your neighbor’s roofer showed up in an unmarked truck and didn’t speak English. Grant Whitlock, who leads our Roofing Company in North Hollywood, built the company around a simple idea: the person at the door should never be a stranger, and the price should never shift after the handshake.
The second reason is the paper trail. Every Mercer Roofing project begins with a written price before any work starts. Not a verbal estimate, not a ballpark. A written line-item price. Every repair carries a written 365-Day Done Right Promise: if it’s not right within a year, we make it right, and a failed repair gets a free second visit. No fine print, no conditions. That’s the same standard we bring to full roof installations across North Hollywood.
Our experience on North Hollywood’s specific housing stock matters too. This isn’t a city of uniform California ranches. It’s a mix of 1940s – 1960s post-war wood-frame stucco tract homes, tight-lot builds pressed against each other, and a dense band of 1960s – 70s dingbat apartments with flat or low-slope roofs. A roofer who only does single-family homes in Valencia will get lost here. We know what to expect on a Cahuenga corridor tear-off before we even set the ladder.
TPO Roofing Installation in North Hollywood
TPO Roofing Installation in North Hollywood is a flat and low-slope roofing system we install regularly on the area’s dingbat-style apartment buildings, garage additions, and post-war homes with nearly flat roof sections. A TPO install on a typical North Hollywood low-slope residential roof runs $9,800 – $16,500, with the bigger spread driven by decking condition and whether the existing roof has multiple patched layers that need full tear-off. TPO is single-ply thermoplastic membrane, heat-welded at the seams, and it handles Valley heat far better than older built-up roofing. Given interior San Fernando Valley summer highs that routinely hit 105 – 110°F, a white TPO membrane reflects heat instead of absorbing it, which also drops attic and cooling loads during July and August.
When TPO Is the Right Call
If your North Hollywood roof is flat or slopes under 2:12, shingles won’t shed water properly and asphalt-based systems will bake and split. TPO is the answer on those sections. We commonly spec it on dingbat apartment roofs along Burbank Boulevard and Magnolia where ponding water at the parapet has killed the original built-up roof. Before any membrane goes down, we walk the deck with the owner and flag any structural questions.
What the TPO Install Includes
The job means full tear-off of the old system down to decking, a deck inspection, and replacement of any compromised sections. Then we install insulation board, mechanically fasten the TPO membrane, heat-weld the seams, and build new flashings at parapets, penetrations, and the shared party wall. Every installation gets the same written 365-Day Done Right Promise as a shingle roof, and the price is in writing before we start.
Shingle Roof in North Hollywood
Shingle Roof installation in North Hollywood is still the standard for the area’s 1940s – 1960s post-war tract homes and stucco-fronted ranches, and a full architectural shingle replacement typically costs $11,500 – $22,000 depending on square footage, decking condition, and how many old layers need to come off. We install GAF, CertainTeed, and Owens Corning architectural shingles most often on North Hollywood pitched roofs, and we stock common colors locally so a homeowner isn’t waiting on a truck from Riverside. Given how hot the San Fernando Valley gets, granule retention and UV resistance are the two things we look at first when recommending a shingle line.
Full Tear-Off, Not a Cover-Over
On North Hollywood homes, we almost always recommend a full tear-off. Too many of these roofs have two or three layers of post-earthquake patch work stacked on original 1950s decking, and layering a fourth shingle system on top is both a code problem and a structural risk. A full tear-off lets us inspect the decking, replace bad wood, and get the weight back within current LA city code load limits. It also means the new roof can be installed to manufacturer spec, which keeps the warranty valid.
New Decking and Ventilation
Half the shingle installs we do in North Hollywood include at least some decking replacement. The 1994 Northridge Earthquake didn’t just shake shingles loose; it cracked rafters and loosened decking that got covered over rather than fixed in the rush of 1994 – 1996 emergency repairs. We also add proper ridge and soffit ventilation on every install because Valley heat cooks attic air, and a roof without airflow will cook the shingles from underneath. That’s a failure mode we see on runs of identical 1950s homes between Victory and Oxnard.
Trusted Brands We Service in North Hollywood
We install and repair all major shingle brands, including GAF, CertainTeed, Owens Corning, Atlas, Tamko, IKO, and Boral. For North Hollywood’s climate and housing stock, GAF architectural shingles and Tamko’s high-wind lines come up most often because they hold granules better under prolonged Valley heat and resist uplift during Santa Ana events. We keep common colors in the local pipeline, which means faster turnaround when a North Hollywood homeowner needs a roof started on schedule around an escrow closing or an HOA deadline.
Common Roof Installation Problems We See in North Hollywood Homes
- Stacked patch layers over original decking. Along the Lankershim and Cahuenga corridors, a roof that looks like a single layer from the curb is often two or three generations of post-Northridge patch jobs stacked on original 1950s decking. The combined weight can push past current LA city code load limits, and we won’t install over it without a full structural deck assessment.
- Blistered and split low-slope membranes. The interior Valley heat sink is brutal on flat and low-slope sections, especially on dingbat apartments. Modified bitumen and old built-up roofs blister, split, and pool at parapet flashings years before their rated lifespan, which is why we see “young” roofs failing at 12 – 15 years.
- Flashings worked loose at shared walls and parapets. Repeated thermal expansion and contraction from 100°F-plus summer days works metal flashings loose at party walls and parapet junctures. On shared-wall stucco homes, that’s where water gets in and where Santa Ana winds find their uplift point.
- Tight-lot access constraints. Many North Hollywood post-war lots are narrow, with fences a few feet from the wall line and no side yard access. Getting material to the roof and staging the tear-off requires planning around neighbors’ parking, shared driveways, and sometimes the city’s work-hour noise ordinance. We scope the site before we quote.
Pricing for Roof Installation in North Hollywood, CA
Here’s what North Hollywood homeowners can expect, in real dollars, as of early 2026:
| Roof Installation Type | North Hollywood Price Range |
|---|---|
| Architectural shingle roof (full tear-off) | $11,500 – $22,000 |
| TPO flat/low-slope roof (tear-off + membrane) | $9,800 – $16,500 |
| Decking replacement (per 4×8 sheet) | $70 – $110 |
| Full structural deck assessment | Included with written quote |
What moves the number: square footage, roof pitch, number of existing layers, decking condition, and site access. A roof on a tight lot off Lankershim where materials have to be hand-carried through a narrow side gate costs more to stage than one with a wide driveway. Every quote we write in North Hollywood is a fixed price in writing before any work starts, and the number doesn’t move unless we open the roof and find structural damage you need to see for yourself. Call (743) 200-8347 and we’ll schedule a free estimate.

FAQs About Roof Installation in North Hollywood
Because so many North Hollywood lots are narrow post-war builds with a fence line a few feet from the wall and no side access. If our crew has to hand-carry tear-off debris through a side gate or stage materials on the street with a parking permit, that labor shows up in the quote. We walk the site before we write the number, so you see the real cost, not a plug figure. Call (743) 200-8347 and we’ll scope it with you.
It requires a notice to the neighbor before the tear-off starts, and usually a conversation about debris falling onto their side, noise timing, and the shared flashing at the wall line. On a mixed-use or attached building in North Hollywood, LA Department of Building and Safety often requires that the new roofing system extend over and properly flash at the party wall rather than stop at the wall line. Our installs include rebuilding that shared-wall flashing correctly, in writing.
Because the 1994 Northridge Earthquake shook loose thousands of roofs, and the 1994 – 1996 emergency repair wave in North Hollywood often added a new layer over the damaged old one instead of doing a full tear-off. Repeated patch jobs in the decades since have buried the original 1950s decking under two or three generations of material. It’s not a corner-cutting story; it’s what a rushed post-quake repair cycle left behind. We open the roof, show you what’s there, and write the fix at a fixed price.
North Hollywood sits in the heat sink of the San Fernando Valley, with summer highs routinely 10 – 15°F above coastal LA and sustained 105 – 110°F stretches. That heat accelerates granule loss on shingles and blisters low-slope membranes. We spec shingles with strong granule retention and UV resistance, and on flat sections we lean toward white TPO membrane that reflects solar heat rather than absorbing it. The climate here doesn’t just shorten a roof’s life; it dictates the product choice from the first meeting.
Yes, in some pockets of North Hollywood, a Historic Preservation Overlay Zone or a specific plan overlay can trigger a review before the permit is issued. The review itself isn’t a month-long process, but it can add a week to two to the permitting timeline. We handle the application, flag the overlay early in the quote, and schedule your install around the review so the roof doesn’t sit open. Call us and we’ll check your address against the overlay map before the first visit.
