Fast, Reliable Roof Replacement Across Altadena
Roof replacement in Altadena typically costs between $14,000 and $28,000 for a standard 1,400 to 2,000 square foot home, with tear-off, decking repairs, and architectural shingles factored in. Most jobs take 3 to 5 working days once permits clear. We know that range holds up across 91001 and 91003, because we work these foothill streets every week. If your roof is leaking or you’re seeing granule loss in the gutters, call (877) 752-3460 and we’ll give you a straight answer on whether repair will hold or replacement is the smarter call. Ruben Acosta runs every Altadena job personally, from the first site walk to the final fastener check.

Why Sunrise Roof Repair Is Altadena’s Preferred Roof Replacement Company
Altadena homeowners keep calling us back for one reason: we inspect before we recommend. When a Pasadena-area contractor tells you a repair will hold, but our crew finds rot under two layers of old shakes near Lake Avenue, we tell you the truth. That honesty matters when a replacement costs real money. We carry GAF, CertainTeed, Boral, and Owens Corning products, so the conversation never starts with “this is the only brand we install.” It starts with your roof, your lot, and your budget.
Working in Altadena means navigating permit counters at the County level and, in some neighborhoods, historic overlay review. We handle that paperwork. It also means knowing that a home on a shaded lot off Mariposa Street will hold moisture longer than one on a sunny corner near Farnsworth Park. Those details shape the quote. Our customers in the Meadows and along Mendocino Lane tell us the same thing: the crew showed up at 7 a.m., kept the street clean, and finished when we said they would.
Response time to Altadena from our East Los Angeles yard is 35 to 45 minutes for assessments. When a storm rolls through the San Gabriels and your ceiling starts staining, that gap matters. Call us before the next rain hits.
Styles & brands we work with






New Roof Installation in Altadena
New Roof Installation in Altadena usually means a full tear-off down to the framing, followed by new decking where needed, underlayment, flashing, and the shingle or tile system of your choice. We do this for homes where the existing roof has failed beyond economic repair, and for additions or new builds on the rare open lot in 91001. Expect to pay $15,500 to $30,000 depending on square footage, pitch, and the number of roof penetrations like chimneys and skylights. On a 1920s Craftsman near Altadena Drive, the decking is often the wildcard: original 1×6 boards spaced apart, not solid plywood, which changes both the labor and the material cost.
Decking First, Then Shingles
Half the Altadena homes we strip reveal decking that cannot support a modern roof on its own. We hand-nail new plywood or OSB over the spaced boards to create a solid nailing surface. This step adds $2 to $4 per square foot, but skipping it voids manufacturer warranties and leaves you with a wavy roof line.
Why We Pull Permits Every Time
Los Angeles County requires a building permit for roof replacement in Altadena. We pull it, schedule the inspection, and make sure the work passes the first time. In historic districts, we also submit the design review package so the project doesn’t stall mid-tear-off.
Reroofing in Altadena
Reroofing in Altadena is the right move when the shingles are near the end of their service life but the underlying decking is still sound. We remove the old shingle layer, inspect the sheathing, repair any soft spots, and install new underlayment and shingles. On a typical 1,600 square foot bungalow, reroofing runs $12,000 to $19,000. On the upper end, if we find two layers to tear off or hidden rot in a shaded valley near Rubio Canyon, the price climbs because the crew has to work slower and replace more wood.
Hand-Nailing Skip Sheathing
Many Altadena homes built between 1900 and 1940 have 1×6 skip sheathing with gaps. We hand-nail shingles on those roofs because a nail gun cannot reliably find solid wood through the gaps. It’s slower work, but it’s what keeps a roof flat and watertight on a 100-year-old house.
Flashing and Valley Detail Work
Altadena’s steep rooflines and multiple gables create long valleys where water concentrates. We use ice-and-water shield in those valleys and custom-bent flashing at every wall intersection. It’s the difference between a roof that looks good from the curb and one that stays dry for 25 years.

Trusted Brands We Service in Altadena
Seven brands, one contractor. We install GAF, CertainTeed, Boral, and Owens Corning systems in Altadena, and we stock the accessories, ridge caps, and flashing that match each product line locally. That means a homeowner near Lake Avenue gets a genuine GAF system with the correct hip and ridge components, not a mixed-brand assembly that voids the warranty. Whether you want a heavyweight architectural shingle from CertainTeed with a 130 mph wind rating or an entry-level three-tab from Owens Corning, we’ll give you an honest comparison of cost, lifespan, and curb appeal. No brand loyalty pushing you one direction. The right material for your roof, not the only brand we carry.
Common Roof Replacement Problems We See in Altadena Homes
- Rot under shaded slopes. The deodar cedars and live oaks that make Altadena beautiful also keep north-facing roof planes damp. We routinely find soft decking under these slopes that requires full replacement before the new roof goes on.
- Mixed roof layers from partial updates. A 1920s bungalow may have original shakes, a 1970s composition shingle layer, and a 1990s patch job all stacked up. Tear-off takes longer, and hidden damage is common. This is why our quotes include a worst-case redeck contingency, not a surprise change order later.
- Steep pitches and narrow driveways. Many Altadena lots slope sharply, and the driveway is often just wide enough for one vehicle. We plan material lifts and dumpster placement carefully so your neighbors aren’t blocked and the street stays passable.
- Historic overlay review delays. If your home falls within a designated historic district, the County may require design review before we can pull the building permit. We handle this paperwork on your behalf so shingle color and material choices don’t stall the project after demolition starts.

FAQs About Roof Replacement in Altadena
Yes, Los Angeles County requires a building permit for roof replacement in Altadena, and if your home is in a designated historic district, you may also need design review approval before the permit is issued. The design review covers visible materials, shingle color, and sometimes roof profile. We prepare both the permit application and the design review package, and we schedule the required inspections after the job. If the historic review is skipped, the project can be halted mid-installation. Call (877) 752-3460 and we’ll check your address against the overlay maps before you commit to anything.
We inspect the site first and plan exactly where the dumpster, material lift, and crew vehicles will sit. On narrow streets like those in Janes Village, we stage materials in the driveway and coordinate with neighbors before blocking any access. Our crews keep the work zone clean daily, and we use hand-carry or a small lift when a truck-mounted crane won’t fit. It adds time, but it prevents disputes and keeps the job moving.
Skip sheathing is the spaced 1×6 board decking common on homes built in the 1900s to 1940s. The gaps between boards mean nail guns can’t reliably fasten shingles, so we hand-nail and often add a new layer of plywood or OSB over the top. If your home still has skip sheathing, expect the decking portion of your quote to run higher than a modern home where the decking is already solid. This is one of the most common reasons an Altadena roof replacement costs more than a comparable job in a 1970s tract neighborhood.
The dense canopy keeps shaded roof planes damp longer, which promotes moss, algae, and deck rot. For homes under heavy tree cover we often recommend algae-resistant shingles, and in shaded valleys we install zinc strips or treat the area to reduce regrowth. We also factor in debris accumulation: if your roof is under live oaks, you’ll want a 50-year architectural shingle with a strong granule bond, not a thin three-tab that will erode under falling branches. Call (877) 752-3460 for a roof-specific recommendation.
Roofing work in unincorporated Altadena is generally permitted from 7:00 a.m. to 7:00 p.m. on weekdays, with more restrictive hours on weekends, and we follow County noise rules for tear-off equipment. We start at 7:00 a.m. sharp, which is part of the Sunrise service identity, but we don’t fire up generators or nail guns before the allowed window. For exact hour restrictions on your street, we confirm with the County during the permit phase and share those times with your neighbors so there are no surprises.
