Fast, Reliable Roof Replacement Across Altadena
Roof replacement in Altadena, CA typically runs $14,000 – $28,000 for a standard architectural shingle roof, depending on square footage, tear-off layers, and whether WUI fire-rated upgrades are triggered. We complete most Altadena re-roofs in 3 – 7 working days once permits clear. If you’re weighing a full replacement on a foothill home, call (833) 589-7971 and we’ll walk the roof with you before quoting anything.
Hollywood Roofing Co has been working Altadena’s streets long enough to know what sits above those 1920s Craftsman ceilings. We’re not driving up from the coast guessing at foothill wind patterns. We know Lake Avenue, we know the neighborhoods north of Altadena Drive, and we know that a roof here isn’t a commodity: it’s the first line of defense against Santa Ana embers and mountain weather. Roland Vega runs our crews, and he holds every Altadena job to the same standard he’d want on his own roof: documented, permitted, and built to the fire code this town now lives by.
Why Hollywood Roofing Co Is Altadena’s Preferred Roof Replacement Company
We’re brand-agnostic across seven manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – which means when we recommend a roof for your Altadena home, it’s matched to your house, not to a supplier contract. For a 1930s bungalow with exposed rafter tails, that might mean a Class A Tamko assembly. For a mid-century ranch in the flats, a CertainTeed architectural shingle. The point is we carry the full range, so the recommendation fits the roofline and your budget.
Homeowners across Altadena call us because we inspect honestly and quote line by line. If a roof can be repaired for another five years, we’ll say so. If it needs full replacement, we document why – with photos, measurements, and a written scope. We don’t run “free inspection” promos that turn into sales pressure. A Roof Replacement from our team starts with a real condition report you can take your time reviewing.
Response time to Altadena matters right now. With Eaton rebuild permits moving through the county backlog, roofers who can’t show up for six weeks are a liability. We schedule Altadena estimates within the week and, once a contract is signed and permits are in hand, we hold your start date. You won’t lose a dry season waiting on a crew.
Styles & brands we work with






Asphalt Shingle Roof Replacement in Altadena
Asphalt Shingle Roof Replacement in Altadena is the most common full-roof job we install here, and it typically runs $14,000 – $22,000 for a standard single-story foothill home with two tear-off layers. On steep Craftsman rooflines with multiple hips, valleys, and penetrations, expect the higher end of that range. The job means full tear-off to decking, inspection of the sheathing beneath, replacement of any compromised boards, new underlayment, and architectural shingles installed to manufacturer wind and fire specs.
WUI Class A Assemblies
Since the Eaton Fire, Altadena’s building department now requires new roof assemblies in most foothill zones to meet WUI Class A fire ratings. That means ember-resistant ridge and eave vents, non-combustible drip edges, and underlayment rated to the current code. We handle the paperwork as part of the permit package, so your assembly passes inspection the first time.
Tear-Off Reality on Older Homes
Altadena’s pre-1950 homes often hide two or three layers of original wood shingle under that top layer of asphalt. That adds labor and disposal cost, and it’s exactly why we quote tear-off by the layer, not by a flat guess. We’ll tell you what’s up there before we start, so the number on your contract matches the number on your invoice.
New Roof Installation in Altadena
New Roof Installation in Altadena starts around $16,000 for a modest Craftsman bungalow and climbs to $30,000+ for larger foothill properties with complex rooflines and Class A assemblies. This is the right scope for homes where the existing decking is too far gone to save, or for Eaton rebuilds going up from new framing. We price new construction separately from re-roof because the labor sequence is different: no tear-off, but a full decking, underlayment, and shingle install from bare trusses up.
Decking Replacement and Structural Repair
On a new build or rebuild, we install 7/16 OSB or 1×6 tongue-and-groove decking depending on the rafter spacing and the engineering spec. If existing framing was charred or rotted, we document it, quote the repair as a written change order, and get your signature before we proceed. No surprises, no “we found it and fixed it, here’s the bill.”
Matching the Craftsman Look
Many Altadena homeowners ask whether architectural shingles can emulate the original wood-shake look. They can. GAF Timberline HDZ and CertainTeed Presidential Shake both offer dimensional profiles that read as hand-split wood from the street, without the fire hazard of the originals. We’ll bring samples to your door in Altadena and walk you through the profiles side by side.
Trusted Brands We Service in Altadena
Hollywood Roofing Co installs GAF, CertainTeed, and Tamko regularly across Altadena, along with the rest of our seven-brand line. That matters here because fire-rated assemblies and wind warranties vary by manufacturer, and the right product for a flatlands ranch isn’t the right product for a canyon-facing Craftsman. We stock local parts for Altadena jobs at our Hollywood yard and order material to arrive days before your crew starts, so we’re not waiting on a distributor during a Santa Ana window. Seven leading brands. One honest recommendation. Matched to your home.

AfterCommon Roof Replacement Problems We See in Altadena Homes
- Ember traps in valleys and behind chimneys. Decades of pine needles and oak leaf litter build up where two roofs meet or where a chimney interrupts the slope. In a wind-driven fire event, that debris ignites from below and burns into the decking. We clear it, inspect the wood beneath, and install ember-resistant venting as standard practice on Altadena tear-offs.
- Original wood shingle hidden under asphalt. Many Altadena owners don’t realize their “asphalt” roof has a full layer of 1920s wood shingle underneath. That hidden layer often hides rotted skip sheathing and compromises the new roof’s wind warranty. We find it during tear-off and price its removal accordingly.
- Failed flashing at exposed rafter tails and penetrations. Foothill Craftsman homes have dozens of pipe boots, dormer intersections, and drip edges that tract crews shortcut. Every one of those is a leak point and, in a wind event, an ignition point. Our flashing details get photographed and inspected before shingles go on.
- Insufficient attic ventilation under WUI code. Older Altadena attics were built for looks, not for the heat and moisture loads of a modern sealed roof. We calculate intake and exhaust ventilation for your new assembly and replace old box vents with ember-resistant models that meet current code.
Pricing for Roof Replacement in Altadena, CA
A full tear-off and architectural shingle replacement on a standard 1,500 – 2,000 sq ft Altadena home runs $14,000 – $22,000.

Every quote is a written line item: tear-off by layer, decking replacement by the sheet, underlayment, vents, flashing, shingles, permits.

FAQs About Roof Replacement in Altadena
Yes, in most foothill zones north of Altadena Drive, the county now requires Class A fire-rated assemblies with ember-resistant vents on any roof replacement, regardless of whether the home predates the code. We document your existing assembly before tear-off, pull the correct permit scope, and schedule the inspection so you’re not caught in the post-Eaton backlog. Call (833) 589-7971 and we’ll tell you what your specific address triggers before you sign anything.
We write a change order. Before we remove a single compromised sheet, we photograph the damage, measure the affected area, and give you a written price per sheet or per linear foot for framing repair. You approve it in writing, we do the work, and nothing appears on your final bill that wasn’t itemized and signed. No verbal “we found rot, trust us” moments on an Altadena roof.
We spec a synthetic underlayment rated for high wind exposure, plus ice and water shield in all valleys, around chimneys, and along eave edges. The foothill freeze-thaw cycle and the Santa Ana-driven rain that hits Altadena sideways mean standard felt is not enough. The material is listed on your quote by brand and square footage.
Yes. GAF Timberline HDZ and CertainTeed Presidential Shake both give you a dimensional, hand-cut look that keeps the character of a 1920s Altadena bungalow without the fire hazard of original wood shingles. We’ll bring full-size samples to your home so you can see them against your siding and roof pitch before you choose.
The honest answer is that no roof sheds every needle, but we reduce the problem by installing valley metal with a smooth, non-stick profile and flashing details that don’t create debris traps. We also recommend ember-resistant gutter guards and, on steep foothill lots, an annual inspection each fall. It’s the one maintenance habit that keeps an Altadena roof out of the ember path. Call (833) 589-7971 to schedule your post-replacement inspection or a free estimate on a full re-roof.
