Fast, Reliable Roof Repair Across North Hollywood
Roof repairs in North Hollywood usually run between $350 and $1,400 depending on what’s going on, and most jobs are done in a single day once we get eyes on the roof. That’s the honest range we quote over the phone before we ever send a tech out. The reason it’s a range and not a fixed number is simple: a vent boot replacement is a small job, a rotted decking section isn’t. If you call (743) 200-8347, a live person answers, asks a few questions about the leak or missing shingles, and schedules an inspection at a time that works for you. We serve North Hollywood daily, from the Valley Glen edge to the NoHo Arts District, and we know what these roofs look like once we get up there.
Why Mercer Roofing Is North Hollywood’s Preferred Roof Repair Company
North Hollywood homes have a reputation among roofers, and it’s not because they’re easy. We’ve worked on enough of them to know what’s waiting under the shingles before we lift the first one. That’s the kind of local knowledge that matters when a homeowner near Lankershim calls about a ceiling stain and you already suspect why it’s there.
Every tech we send to North Hollywood is background-checked and identity-verified under the Threshold Verified standard. Before they ring your doorbell, we send their name and photo to your phone. They show up in a clean, marked uniform and badged with a photo ID. That’s not a perk. It’s the baseline, and we put it in writing.
Grant Whitlock, who leads our team, built Mercer Roofing around one belief: a homeowner should never wonder who’s on the other side of the door. That’s why we write the price before we work, include a written guarantee on every repair, and back the whole thing with our 365-Day Done Right Promise. If it’s not right within a year, we make it right.
Commercial Roof Repair in North Hollywood
Commercial roof repair in North Hollywood means working on a very different animal than a single-family home. Think 1960s and 70s dingbat-style apartment buildings along Magnolia and Burbank Boulevard, low-slope built-up roofs, scuppers, parapet walls, and membranes that have been baking under San Fernando Valley heat for decades. A commercial repair here typically costs $800 to $3,500 depending on the membrane type and how much patching has already been done. We’re not bidding a handyman patch. We’re bidding the repair that stops the leak for good, with a written price before we start.
Built-Up Roof Patching and Membrane Repair
Most North Hollywood apartment buildings from that era have built-up roofs, layers of asphalt and felt that eventually crack and split. When water pools near a clogged drain or a parapet wall, it works into those splits and shows up as a ceiling stain two floors down. We patch the membrane, but we also check the flashing at the parapet, because that’s where the real leaks usually start.
If we find multiple old patch layers, we’ll tell you what that means before we quote. Sometimes the right call is a full re-cover. Sometimes it’s a repair. Either way, you’ll see numbers on paper before we touch anything.
Parapet Flashing and Uplift Repairs
Santa Ana winds don’t hit coastal LA the way they hit North Hollywood. When the wind comes down the 170 and across the Valley, it pulls at parapet wall flashing and can lift it right off the membrane. We resecure and reseal those flashings with proper materials, not caulk slapped over the old seam. That’s a $450 to $900 repair on most Valley apartment buildings, and it’s one of the most common calls we get in November and December.
Roof Leak Repair in North Hollywood
Roof leak repair in North Hollywood starts at about $350 for straightforward vent boot or pipe flashing replacements and climbs to $1,200 or more when we have to open up decking or reset chimney flashing. The frustrating truth is that leaks here are rarely where they look. A stain on the bedroom ceiling might be coming from a nail pop thirty feet away, water traveling along a rafter before it drips down. That’s why we trace the leak, we don’t just caulk the spot.
Finding Leaks on Older Tract Homes
North Hollywood’s post-WWII wood-frame stucco homes, the ones built in the late 1940s through the 1960s, share a few leak-prone features. Low-pitch roof sections hold water longer. Original flashing at the chimney and walls has been through 60 summers of expansion and contraction. And in some cases, two or three old patch jobs from the post-Northridge repair wave are hiding the real problem underneath.
We inspect from the attic side first when we can, because the underside of the decking tells the true story. Then we go up top. Two angles, one diagnosis, one written price.
Water Pooling on Flat and Low-Slope Sections
Lots of North Hollywood homes have flat or nearly flat roof sections, either original or added later. When water pools and sits for days after a storm, the membrane eventually fails. We patch those with materials matched to your existing roof, but we also mark the low spots and tell you whether a longer-term fix makes more sense than repeated patches. You’ll get that recommendation in writing, with numbers, before we proceed.
Trusted Brands We Service in North Hollywood
We install and repair shingle roof systems from brands that hold up under Valley heat: GAF, Atlas, and CertainTeed are the ones we quote most often in this area. That matters in North Hollywood because sustained 105° to 110°F summers are brutal on asphalt shingles. Cheap off-brand shingles lose granules fast here, and a ten-year-old “budget” roof can look like it’s twenty. Whatever brand is on your roof now, we can match the shingle, the color, and the profile close enough that the repair won’t look like a patch job. Parts are stocked locally, and most repairs don’t wait on shipping.
Common Roof Repair Problems We See in North Hollywood Homes
- Post-earthquake patch layers hiding rotted decking. Torn off what looked like a single-layer roof near Lankershim and found three generations of patch jobs stacked on original 1950s decking. That’s not rare here. That’s standard.
- Granule loss and shingle blistering from Valley heat. Shingles bake at 110°F for weeks straight, shed granules into the gutters, and start to fail years before their warranty says they should. A roof that’s ten years old here may perform like one that’s twenty in coastal LA.
- Flashing failures at parapet walls and chimneys. Thermal expansion works nails loose and separates sealant at the exact spots where your roof meets a wall. Santa Ana winds do the rest.
- Pooling water on low-pitch and flat roof sections. Whether it’s a 1950s tract home or a 1970s apartment building, standing water is roof cancer. We find it, fix the leak, and tell you why it pooled in the first place.

FAQs About Roof Repair in North Hollywood
Because the 1994 Northridge earthquake sparked a wave of emergency patching that left many homes with multiple shingle layers over original 1940s – 1960s decking. Once we open the roof and find compromised decking or code-violating load weights, a replacement is often the only responsible path. The key is that we write an allowance into the contract for that possibility, and you approve any surprise cost in writing before we proceed. Call (743) 200-8347 for an inspection that tells you what’s actually under your shingles.
North Hollywood sits in the Valley’s heat sink and endures sustained summer highs of 105° to 110°F, up to 15°F hotter than Santa Monica or Redondo Beach in the same week. That heat accelerates granule loss on asphalt shingles, blisters and splits low-slope membranes, and causes repeated thermal expansion that loosens flashing. A roof here ages faster, so repairs and replacements come sooner. We factor that into every repair recommendation, because patching sun-damaged shingles that will fail again next summer isn’t a repair, it’s a Band-Aid.
Expect a full tear-off. LA city code limits how many roofing layers can sit on a structure, and post-earthquake patch jobs in North Hollywood often push homes past that limit. Once we pull back the layers and see what we’re dealing with, we’ll write a change order for any additional work. You approve it before we proceed. You’re never surprised by a bill. Call (743) 200-8347 and we’ll inspect your roof and tell you upfront what a permit-triggering repair would involve.
Yes. We work on built-up roofs, modified bitumen, and single-ply membranes on the 1960s and 70s dingbat-style apartment buildings common throughout North Hollywood, especially along Burbank Boulevard and Magnolia. Pooling water, membrane splits, and parapet flashing failures are the usual suspects. We’ll diagnose the leak, quote the repair in writing, and tell you whether a full restore makes more financial sense than another patch.
Look past the bottom-line number and compare three things: whether the quote includes a written price before work starts, whether the repair carries a written guarantee, and whether the contractor will show you photos of the damage before and after. Some bids look cheaper because they skip the decking assessment or reuse old flashing. Our quotes include all of it, in writing, with a 365-day guarantee. If our number is higher, that’s what it’s paying for. Call (743) 200-8347 for a detailed written quote and we’ll walk you through it line by line.
