Roofers in Altadena, CA
Roof inspection in Altadena is where every honest roofing decision starts, and it’s how owner-led Marquis Roof Repair has served this town since 2014. Altadena’s 1920s-to-1960s ranches and bungalows hide problems that newer tract homes don’t: original board sheathing, decades of oak litter packed into valleys, and flashing that’s been baked by 1,000-foot-plus sun exposure. We investigate before we recommend. If you’ve noticed a stain on the ceiling or shingles in the yard after the last Santa Ana, call (866) 705-2978 and we’ll start with the roof, not a sales script.
Why Altadena Homes Are Different
Altadena sits at 1,000 to 1,400 feet at the foot of the San Gabriels, which means hotter summer days and stronger UV than Pasadena just down the hill. Roof surfaces here swing hard, day to night. Asphalt shingles shrink and crack. Rigid tile and flashing fasteners fatigue. Then the Santa Ana winds come through and tear off whatever was already failing. We see the pattern repeat across 91001 and 91003: lifted ridge caps and dried-out fascia on the south-facing pitches, almost always on homes where the oak litter has sat in the valleys for years.
The housing stock adds another layer. Most Altadena homes are wood-frame California ranches and bungalows built before the 1960s, with original board sheathing and low-slope porch roofs. A large share have had unpermitted additions and patio covers over the decades. When a re-roof reaches the decking, we often find skipped framing or rotted sheathing that no one touched since the original build. And because Altadena is unincorporated Los Angeles County rather than a chartered city, which code applies to a 60-year-old roof is not always obvious. We figure that out before we price anything, so the estimate you get matches the work the county will actually inspect.
Styles & brands we work with
Our Main Altadena Services
Most Altadena homeowners call us for one of two reasons: a targeted fix they need done right the first time, or a full roof that has finally reached the end of its life. Both start with the same honest diagnosis.
Roof Repair in Altadena
Repair work here is usually about the roof’s weak points, not the field shingles. The valleys under big deodar cedars and live oaks collect leaf litter that holds moisture against the shingles. The porch roofs on 1940s and 1950s bungalows have low slopes that many original installers under-flashed. And the south-facing pitches overlooking the San Gabriels take decades of direct sun that turns ridge caps brittle. When we repair in Altadena, we match the existing material where possible and tell you plainly if a patch is a patch or if you are throwing money at a roof that is already gone. See Roof Repair in Altadena for the full scope of what we handle.
Roof Replacement in Altadena
Replacement in Altadena is rarely just a tear-off and lay-down. At least half our full replacements involve rebuilding or reframing skipped decking before new material goes on. Older homes often have two or three layers of old shingles, and the original board sheathing underneath is frequently spongy in the valleys and along the eaves. Because Marquis works across seven manufacturer lines, the right material for your roof is available whether you want the most budget-sensible asphalt or a heavier architectural or tile profile. We pull permits, schedule county inspections, and keep the job moving until final sign-off. The full picture is on our Roof Replacement in Altadena page.

Roof Inspection in Altadena
In Altadena, a roof inspection is the difference between fixing a small problem for a few hundred dollars and discovering it as a five-figure surprise after a winter storm. Homes here are mostly 1920s-to-1960s wood-frame ranches with original board sheathing, low-slope porch roofs, and decades of exposure to mountain sun and Santa Ana wind. Our Roof Inspection starts with the roof’s history, then works from the attic to the ridge, and ends with a written line-item report you can act on, whether that means a two-hour repair or a planned replacement.
Roof Inspection Services

You have a water stain on the ceiling, your home is over 20 years old, or the last Santa Ana dropped tree branches on the roof.

We walk the roof, open the attic access where possible, check flashings and valleys, run water on suspect areas when needed, then hand you a written report with photos and a prioritized repair list.
Roof Estimate
Signs you need it
You are weighing repair against replacement and want firm numbers for each option before making a decision.
What it costs in Altadena
A roof estimate in Altadena runs $0 to $300; detailed replacement estimates are free with an inspection, while repair-only quotes are free to prepare and good for 30 days.
How we do it
We take roof measurements, note the decking condition, identify the material on your home, and price the repair and replacement paths separately so you can compare them honestly.
Free Roof Inspection

You have a leak but you are not sure how severe it is, and you want a professional look before you commit to anything.

How we do it
We locate the leak source from the attic side first, then confirm on the roof surface, and give you a straight answer on whether you need a small patch, a section repair, or a full replacement.
Roof Inspection Companies
Signs you need it
You are buying or selling a home in Altadena and need a documented inspection from a roofing specialist, not a general home inspector.
What it costs in Altadena
Roof inspection companies in Altadena charge $195 to $400 for a standard single-family roof, with pre-purchase inspections at the higher end because they include an extra layer of attic and flashing documentation.
How we do it
We photograph every finding, date it, note the remaining service life of each roof component, and give the report to you same-day, formatted for either closing or an insurance claim.
What Roof Inspection Costs in Altadena
| Item | Typical range in Altadena |
|---|---|
| Standard residential roof inspection | $195 – $400 |
| Free leak or storm-damage inspection | Free – credited toward work |
| Detailed replacement estimate | Free with inspection |
How long does a roof inspection take in Altadena?
Most inspections run 45 to 90 minutes depending on roof size and how many attic access points the home has. You get the report the same day, not a callback next week.
Do you climb the roof or just look from the ladder?
We walk the roof when it is safe to do so and inspect from the attic side as well. The problems that matter in Altadena, like valley rot and lifted ridge caps, are often invisible from the ground. Call (866) 705-2978 to schedule yours.
Brands We Service in Altadena
Marquis Roof Repair is authorized to install products from seven major manufacturers, including GAF, CertainTeed, Tamko, and Boral. That breadth matters in Altadena, where the right material changes based on slope, oak cover, and how much afternoon UV the roof takes. We keep common components in local supply, so most repairs do not wait on a regional order. See our brands for the full line card.

In Altadena, the two biggest price drivers are decking condition and access. Older homes with original board sheathing frequently need $2,000 to $6,000 in reframing and decking work before new material goes down, and steep mountain-adjacent lots add time and safety cost. Every estimate we give is a written line-item price, and the number does not change once we start unless the decking rot was hidden under layers we could not have seen before tear-off. We tell you the worst case up front, not after you are committed.

FAQs About Roofers in Altadena
Yes. Altadena is unincorporated Los Angeles County, so roof replacements require a county building permit and a final inspection. Marquis Roof Repair pulls the permit for you, schedules the inspection, and stays on site until sign-off. Repairs that do not alter the roof structure or change the material type usually do not require a permit, but we confirm case by case before touching anything.
After a wind event, we prioritize active leaks and exposed decking over cosmetic repairs. Most Altadena homeowners get an inspection within 2 to 3 business days, and emergency tarping can often be routed sooner. If water is coming in, we treat it as urgent regardless of where you are on the schedule.
We will. We document damage with dated photos, write the repair scope in insurance-ready language, and meet your adjuster on site if you want us there. You still deal directly with your insurer on coverage and payment, but we make sure the technical details in the claim are accurate and complete.
Marquis Roof Repair serves Altadena from first inspection to final shingle, with seven manufacturer lines and one point of contact. Call (866) 705-2978 to schedule your free estimate.

What Altadena Customers Say
"Added a ridge vent and cleared the blocked soffit vents. Attic temperature in the summer dropped noticeably and the upstairs is livable now."
— Grace Kim"Flashing where the roof meets the chimney had never been done right by the original builder. He rebuilt it properly with step flashing instead of just running a bead of caulk over it like the last two people did."
— Miguel Vargas"Storm took part of the ridge off at night. They tarped it the same evening so the rain didn't get in, and did the real repair the following week."
— Ernesto Rodriguez
