Fast, Reliable Roof Installation Across Altadena
A full roof installation in Altadena typically runs between $14,500 and $32,000 for a standard single-family home, depending on square footage, tear-off layers, and the material you choose. Most Altadena projects take 3 to 7 working days once we start, and we’ll give you a written price before any work begins. If you’re dealing with an older Altadena home with multiple old roof layers, count on a full tear-off first, which changes both the timeline and the number on your invoice. Call (626) 389-1956 to schedule a free estimate.
We know Roof Installation in Altadena means working on homes that were built when Franklin Roosevelt was president. That’s not a problem. It just means the job starts with an honest look at what’s under the existing shingles before we quote you a price we both can live with.
Why Crestview Roofing Co Pasadena Is Altadena’s Preferred Roof Installation Company
We’ve spent years working on Altadena’s specific housing stock: low-slung ranch homes on Lake Avenue, Craftsman bungalows off Mendocino Lane, and mid-century boxes near Altadena Drive where the original roof framing was never sized for anything heavier than wood shake. That local knowledge matters when you’re deciding between architectural shingles and standing seam metal, because the right answer depends on your roof pitch and what your rafters can carry. We don’t guess. We inspect first, then price.
Altadena homeowners consistently tell us the same thing: they want a roofer who answers the phone, shows up when they say they will, and doesn’t change the price after the dumpster arrives. That’s exactly how Crestview Roofing Co Pasadena operates. Every installation includes a written price before work starts, before-and-after photo documentation, and a live trackable arrival time so you know when our crew pulls up. The number on your written quote is the number on your final invoice.
Dylan Pace leads our team, and he’s built the company around one simple idea: roofing estimates should not read like a mystery novel. You shouldn’t have to wait until the bill arrives to learn what the job actually cost. That’s why we work under The Relay Visibility Guarantee, a standard that covers every job we do in Altadena.
Styles & brands we work with
Shingle Roof in Altadena
A shingle roof in Altadena is the most common installation we handle, and for good reason: architectural asphalt shingles from CertainTeed or Owens Corning strike the right balance between fire rating, weight, and cost for the ranch homes and Craftsman bungalows that dominate this area. In Altadena’s market, a full architectural shingle roof installation runs $14,500 to $24,000 for a typical 1,500 to 2,200 square foot home, including tear-off and disposal of the old roof.
Here’s the part that matters for Altadena specifically. Many homes up and down Lake Avenue and around the Christmas Tree Lane corridor have original cedar shake buried under two or three layers of composition shingle. That means tear-off weight, and lots of it. We account for every layer in your quote, so there’s no surprise disposal charge halfway through the job.
Architectural Shingle Systems for Ranch Homes
Low-pitch ranch roofs are common in Altadena, and they need correct starter strips and nailing patterns or the first Santa Ana wind will peel the shingles right off. We install with six nails per shingle on high-wind zones and use ice and water shield in the valleys. That’s standard for us, not an upgrade.
Class A Fire-Rated Shingle Options
Given Altadena’s position at the base of the San Gabriel Mountains, we recommend Class A fire-rated shingles on every full replacement we quote. Brands like CertainTeed and Owens Corning make architectural shingles with fiberglass mats that meet Class A fire resistance without costing much more than standard options. We’ll show you the fire rating on the wrapper before we nail a single shingle down.
Standing Seam Metal Roof in Altadena
A standing seam metal roof in Altadena is a serious investment, running $22,000 to $38,000 on most homes here, but it’s often the smartest long-term choice given our wildfire exposure and intense high-desert sun. The vertical seams give embers almost nothing to grab, and a metal roof will typically outlast two or three shingle roofs. For a mid-century modern home near Altadena Drive with a low slope, standing seam is frequently the best-looking and best-performing option.
Older Altadena framing sometimes needs beefing up before standing seam can go down, especially if you’re on a 1940s ranch where the rafters were sized for wood shake. We check the structure before we quote, not after the old roof comes off.
Fire Resistance and Ember Protection
Metal roofing is non-combustible, which is a real advantage when you live below the Angeles National Forest. During wildfire season, a standing seam roof doesn’t burn, doesn’t smolder, and doesn’t give embers a foothold. We pair it with ember-resistant venting for full protection.
Weight Considerations on Older Homes
Standing seam metal is actually lighter than architectural shingles in most cases, which means it often works on older Altadena homes where tile would require structural work. That’s a real selling point for Craftsman bungalows with original 1920s framing. We’ll give you an honest read on whether your rafters can handle your first choice before you spend a dollar.
Trusted Brands We Service in Altadena
We install and service roofs using materials from CertainTeed, Owens Corning, IKO, and Atlas. That means you’re never stuck waiting on a specialty part when your Altadena roof needs attention. Our relationship with these manufacturers means we can source exact-match shingles quickly when repairs call for it, and we carry the most common colors and profiles for Altadena’s older neighborhoods. If you’ve got a CertainTeed roof from a previous owner and need a section matched after storm damage, we can usually make that happen without a six-week wait. Material quality is never the question on our jobs. The brand names are on the invoice, and we’ll show you the manufacturer warranty documentation before you sign anything.

AfterCommon Roof Installation Problems We See in Altadena Homes
- Hidden dry rot in original decking. Multiple composition layers trap moisture, and by the time we tear off, the decking underneath can be rotten in patches around chimneys, valleys, and skylights. We find it, we show you a photo of it, and we price the replacement before we proceed.
- Santa Ana wind damage from skipped starter strips. Low-pitch ranch roofs are unforgiving when installers skip starter strips or use too few nails. After a big wind event, we see shingles lifted and folded back on homes all over Altadena. We install to manufacturer high-wind specs every time.
- Ember intrusion through unscreened soffit vents. During wildfire season, embers can enter through old vents and flashings and ignite dried-out cedar shake remnants under the roof. We recommend and install ember-resistant venting on every full replacement in Altadena.
- Undersized rafters from original 1920s construction. In neighborhoods like Christmas Tree Lane, we regularly find original rafters that were never engineered for modern roofing loads. We address structural concerns before new materials go on, not after.
Pricing for Roof Installation in Altadena, CA
Here are honest ranges for Altadena’s market. A standard architectural shingle roof on a 1,500 to 2,200 square foot home runs $14,500 to $24,000. Standing seam metal runs $22,000 to $38,000 depending on gauge, seam profile, and whether we need to do structural reinforcement first.

FAQs About Roof Installation in Altadena
We add a tear-off allowance to your written quote before we start. That covers the extra labor and disposal of the original cedar shake layer, which is heavier and bulkier than composition shingle. On a 1940s ranch near Christmas Tree Lane, our crew removed three layers of composition shingle to expose the original cedar shake, then found rotted decking around the valleys and undersized rafters never meant for modern loads. We replaced the decking, installed ice and water shield in the valleys, and reframed the eaves before laying a full GAF architectural shingle system with a new ridge vent. We’ll do the same kind of careful work on your home, and the price for it will be in writing before we touch the first layer. Call (626) 389-1956 for an exact quote.
Altadena’s location in a very high fire hazard severity zone means Class A roofing is required on any full replacement. A Class A roof assembly includes the roofing material itself plus underlayment and venting that meet fire resistance standards. We install Class A systems by default in Altadena using CertainTeed, Owens Corning, IKO, or Atlas products paired with ember-resistant vents. We’ll pull the permit, and we’ll make sure the roof assembly passes inspection the first time. Call (626) 389-1956 and ask us about fire-rated options for your specific roof.
No. The original cedar shake underlayment on a 1920s Altadena home is almost never reusable. After a century of heat cycles, it’s brittle, dry, and often rotten in spots. Reusing it would compromise the new roof and void most manufacturer warranties. We remove it, inspect the decking underneath, and install fresh underlayment that meets current code before the new roof goes on. You’ll get a photo of the cleaned decking before we lay the first underlayment sheet. Call (626) 389-1956 to schedule your free estimate.
Most Altadena ranch homes have a 3:12 to 5:12 pitch, which is low enough that standing seam metal needs careful panel layout and sealing at the seams. Low-pitch roofs are more exposed to the sun, so panel expansion and contraction are bigger factors here than on steeper roofs. We use standing seam profiles rated for low-slope applications and install them with the right clip systems for thermal movement. Your roof’s specific pitch is one of the first things we measure when we come out for the estimate. Call (626) 389-1956 and we’ll bring a measuring wheel and give you an honest read.
Altadena homes need ember-resistant venting because wind-driven embers from the San Gabriel Mountain foothills can enter through standard roof vents and ignite dried-out wood shake remnants or framing. Ember-resistant vents have a finer mesh that blocks burning debris while still letting the attic breathe. We install them on every full roof replacement in Altadena and we’ll include them as a line item on your written quote so you know exactly what you’re paying for. Call (626) 389-1956 for a free estimate on your Altadena roof.
