Fast, Reliable Roof Replacement Across Altadena
Roof replacement in Altadena typically runs $14,000 – $32,000 for a standard single-family home, with most jobs finishing in 3 – 7 working days once permits clear LA County Building & Safety. We’re at home on Altadena’s tight bungalow lots off Lake Avenue and Lincoln Avenue, where staging a dumpster and material drops takes real planning. Call (833) 467-4901 and Neil Stratton will walk you through what your specific roof needs, starting with an inspection that tells you straight whether repair or replacement actually makes sense.
Why Altadena Homeowners Call Us for Roof Replacement
We inspect first, recommend second. That’s not a slogan; it’s how we keep Altadena homeowners from paying for a full tear-off when a targeted repair would buy another five years. Neil Stratton built this company around that diagnostic-first approach, and it’s why so many of our Altadena calls now come from referrals off Altadena Drive, Mendocino Lane, and the President Streets corridors.
One contractor handles the whole job. The crew that inspects your roof is the same crew that replaces it. No subcontracted assessment, no hand-off between an inspector who’s never met the install team and a crew that never saw the original photos. For Altadena’s older homes, where heat damage and dry rot hide under old shingles, that continuity matters.
Seven brands. One contractor. We carry GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means the material recommendation follows your roof’s needs and your budget, not whatever happens to be in our yard this week. If Atlas is backordered or a specific GAF line doesn’t suit the pitch of your bungalow, we have immediate alternatives.

Asphalt Shingle Roof Replacement in Altadena
Asphalt shingle roof replacement is the most common job we do in Altadena, and the right choice for most of the 1920s – 1950s bungalows and ranch homes that survived the Eaton Fire. A typical tear-off and re-shingle here runs $14,000 – $24,000 depending on square footage, pitch, and how much decking needs replacement once we strip the old layers.
Tear-Off vs. Overlay
On Altadena’s older homes, we almost always recommend a full tear-off. The original 3-tab shingles on a 1948 ranch often hide heat-burned underlayment or dry-rotted decking, and overlaying new shingles on that is a short-term fix that traps moisture. A tear-off lets us inspect the decking, replace what’s compromised, and start clean.
Class A Fire-Rated Assemblies
After the Eaton Fire, LA County now expects Class A roof coverings and ember-resistant detailing on almost every replacement in Altadena, even like-for-like tear-offs. That means closed valleys, ember-resistant vents at the roof-to-wall intersection, and gutter guards where the deodar canopy drops needles. We build those into the quote from day one, not as a change order mid-job.
New Roof Installation in Altadena
New roof installation in Altadena covers two situations: a burned lot being rebuilt under current WUI code, or a homeowner replacing an original roof so far gone that the decking and framing need attention too. New construction roofing here typically runs $20,000 – $32,000 and includes the full assembly: decking, underlayment, shingles, flashing, venting, and ember-resistant details.
New Construction and Rebuilds
For lots that burned in 2025, the County permit path now includes WUI roofing requirements that didn’t exist when the original 1940s roof went on. That means the roof assembly gets reviewed for fire rating as part of the building permit, not as a cosmetic afterthought. We coordinate with the County review so the roof passes inspection the first time.
Replacement Down to the Decking
When decking replacement is unavoidable, the cost moves toward the higher end of the range because we’re installing new plywood or OSB, not just covering what’s there. On Altadena’s steep-pitched bungalows, that work is slower and requires careful staging. Our quotes on Roof Replacement always show decking replacement as a line item so you see exactly what’s covered.
Trusted Brands We Service in Altadena
We stock and install Atlas, Tamko, Boral, and GAF among our seven-brand portfolio, which means an Altadena homeowner can choose from entry-level 3-tab up to premium architectural shingles with a manufacturer warranty that varies by product line. If you’re filing an insurance claim for Eaton Fire damage and your policy specifies a particular brand, we can match it. That multi-brand capability also keeps a replacement moving when one manufacturer has a supply delay. Call (833) 467-4901 and we’ll tell you which brand fits your roof, your pitch, and your budget.

AfterCommon Roof Replacement Problems We See in Altadena Homes
- Narrow driveway staging. Many Altadena lots, especially off Altadena Drive, have one narrow driveway and mature deodar cedars overhanging the ridge. That leaves no room for both a dumpster and material drops, and a crew that doesn’t plan staging blocks the neighbor’s shared drive or ladders against canopy limbs.
- Heat-burned decking under old shingles. Homes that survived the fire often have decking that baked in radiant heat, or dry rot from years of needles and twigs sitting in the valleys. A quote that doesn’t account for decking replacement after tear-off surprises the homeowner with a mid-job change order.
- Ember entry at roof-to-wall intersections. We regularly find gaps at the roof-to-wall intersection and unrated attic vents on Altadena homes that look fine from the street. These are exactly where embers entered during the fire. County now reviews this junction on permitted replacements, and retrofitting it is standard in our quotes.
- Original 3-tab shingles on steep pitches. The 1940s and 1950s bungalows off Lake and Lincoln often have steep roofs with original 3-tab shingles that have failed at the nail lines. Replacing these means careful staging and often new fascia where water has wicked behind the old shingle edges.
Pricing for Roof Replacement in Altadena, CA
Expect to budget $14,000 – $32,000 for a full roof replacement in Altadena. A straightforward tear-off and re-shingle on a 1,400-square-foot ranch runs $14,000 – $18,000. A larger two-story home with steep pitch, decking replacement, and a Class A fire-rated assembly runs $22,000 – $32,000. New construction roofing on rebuild lots starts around $20,000 and rises with complexity and material tier. The biggest cost drivers in Altadena specifically are access staging, decking replacement after tear-off, and the WUI ember-resistant detailing the County now expects.

FAQs About Roof Replacement in Altadena
Narrow driveways and dense cedar canopy add real cost to an Altadena roof replacement, typically $1,000 – $3,000 depending on how severely staging is constrained. That figure covers canopy protection, manual material handling when a boom truck can’t reach, and possibly shorter dumpster windows. We quote access costs as a separate line item so you can compare bids apples to apples. Call (833) 467-4901 for an exact figure on your lot.
Many surviving roofs do, even when they look intact from the street. Radiant heat can bake underlayment until it fails months later, and embers may have entered at the roof-to-wall intersection or attic vents without leaving visible damage. A standalone inspection is the only honest way to know. We inspect first and recommend replacement only if heat damage, water intrusion, or age justify it. Call (833) 467-4901 to schedule an inspection.
Yes. Altadena is unincorporated LA County, so roof replacement permits go through County Building & Safety rather than a city hall. Post-Eaton-Fire, the permit review includes fire-rated assembly and ember-resistant vent compliance even for like-for-like tear-offs. We pull the permit and coordinate the inspections as part of the job. Call (833) 467-4901 and we’ll tell you what your specific roof needs.
We tarp canopy limbs overhanging the ridge, give written notice to adjoining homeowners before tear-off, stage in the driveway so shared drives stay clear, and sweep the gutter line every evening. If there’s a shared party wall, we cover it and clean it daily. That discipline costs nothing in contract terms but saves a neighbor complaint that can stall a job. Call (833) 467-4901 and we’ll walk your specific lot.
Put them side by side on five line items: decking replacement allowance, underlayment and ice and water shield details, ember-resistant vent and valley treatment, dumpster and staging access, and whether the permit includes the WUI review. On a surviving bungalow, a lower bid that omits decking replacement or ember-resistant detailing will cost more once the work starts. Call (833) 467-4901 and we’ll help you read the other quote before you decide.
