The community is unincorporated, so Los Angeles County handles permits, and the January 2025 Eaton Fire means checking for ember damage and fire-rated materials first.

Altadena foothill homes after the Eaton Fire
CAL FIRE reports the January 2025 Eaton Fire destroyed 9,419 structures, and much of that loss was in and around Altadena. A roof on a house that survived is not automatically fine because the structure stood. Embers can lodge in vents and under tabs, and heat can age shingles early.
For these homes, we inspect, photograph and document what we find, then write a repair estimate you can share with your insurer. Negotiating with the insurer belongs to the policyholder or a licensed public adjuster.
Altadena rain, Santa Ana wind and debris on the foothill side
Altadena gets more rain than Los Angeles does because moist air lifts over the San Gabriel Mountains. The 21-inch average hides big swings, with a record of 48.47 inches in 1983 and 7.70 inches in a single day in 1938. Falls bring warm, windy weather that packs gutters with oak leaves and needles.
Both problems land on the same spots: valleys, eaves and the joint where roof meets chimney or wall. Our roof repair work starts there.
Median home built 1946 and what that means up top
Altadena's housing is among the older sets we cover. With 77% owner-occupied and a median build year of 1946, many families have lived under the same roof layers for decades. Older homes may have spaced boards, multiple roof layers or materials that may contain asbestos. Signs of asbestos in old material call for lab testing before it comes off.
Christmas Tree Lane, Lake Avenue and the streets below the mountains
Altadena stands at about 1,358 feet, with the Angeles National Forest rising directly behind it and Eaton Canyon along its eastern edge. Lake Avenue climbs toward the Cobb Estate and Farnsworth Park, and Fair Oaks Avenue and Altadena Drive cross the community east and west. Christmas Tree Lane, a 0.7-mile stretch of Santa Rosa Avenue, has 110 giant deodar cedars, and trees that size drop needles and limbs onto the roofs beneath them.
The older housing varies by block. Elisha Paul Janes built 160 homes here in 1924 to 1926, with steep roofs and multiple gables, and the neighborhood was designated a heritage area in 2002. That means more valleys to flash and more height to work at than on a ranch roof. If you own in a designated area, ask the county what review applies before you choose a material or color.
Los Angeles County permits and rebuild roofing in Altadena
Altadena is unincorporated, so Los Angeles County handles its permits and plan review. A rebuild has to meet the fire code that applies to your parcel. The Wildland-Urban Interface Code, Part 7 of California's building code, became effective on January 1, 2026.
Los Angeles County has set up a permit center in Altadena on West Woodbury Road for rebuild questions, along with a Unified Permitting Authority for residential rebuilds. Rules for post-fire work have changed over the past year, so confirm today's requirements with the county for your parcel.
Ask for the covering rating in writing, check the county's current requirements, and see our Class A fire-rated roofing page for the options we would discuss.

Roofing questions from Altadena
Who issues roofing permits in Altadena?
Los Angeles County does. Altadena is unincorporated, with no city building office and no LADBS. Decide in the contract who files and who calls for the inspection. A Van Nuys customer credits us with taking care of the permit process, and for an Altadena parcel we would check the county's current requirements, including any rebuild guidance, before work starts.
Should I replace my Altadena roof if the house survived the Eaton Fire?
Not always, but get it checked. Embers, heat and ash can damage vents, flashing and shingles in ways you cannot see from the ground. We can inspect, photograph and document the damage and write a repair estimate. Talking terms with your insurer is for you or a licensed public adjuster.
Do I need a Class A roof in Altadena?
It depends on your address. Class A is the highest fire rating a roof covering can carry, and Very High Fire Hazard Severity Zones require it. The state revised its fire hazard maps in 2025, so check your address on CAL FIRE's viewer, then ask the county what applies before choosing a material.
Where do Altadena owners take roofing and rebuild questions in person?
Los Angeles County runs a permit center in Altadena on West Woodbury Road, set up for fire rebuilds and repairs in the community. Confirm hours and current requirements with the county before you go, since rules for post-fire work have been changing. Bring photos of the roof, which we can supply after an inspection.
Do the 1920s gabled Altadena houses need a different roofing approach?
Steep, multi-gable roofs have more valleys, hips and wall joints than a simple ranch roof, and every one is a place water can enter. They also take more labor and fall protection. Altadena has a heritage-designated 1920s tract of such homes, so we price each valley and flashing run on its own line.
How does Altadena's foothill rain change what a roof needs?
Altadena gets about 21 inches in an average year, far more than the valley floor, and single storms have dropped several inches in a day. That raises the stakes for valleys, step flashing and gutters compared with a dry-side roof. We look at where water is meant to go before we talk material.
Services in Altadena
- Class A Fire-Rated Roofing
Altadena sits at the foothill edge where the Eaton Fire burned. A Class A rated assembly is a sensible choice to discuss for any new roof, and may be required depending on your address.
- Roof Replacement
At a median build year of 1946, plenty of Altadena roofs wear a second or third covering. Tear-off lets us inspect the boards and ember-prone details before new material goes on.
- Emergency Roof Repair
Damaged homes that are still standing may need a tarp before the next rain. We will set the earliest visit we can, then photograph what we find for your records.
- Roof Repair
Altadena's heavy foothill rain, over 21 inches in an average year, tests flashing and valleys on older roofs. Repair starts by finding where the water is entering.
- Gutters
Oak leaves, pine needles and ash-laden debris fill foothill gutters quickly. Clean runs reduce trapped debris along the roof edge and carry storm water away from older foundations.
- Roof Insurance Claims
Eaton Fire homes that stood may still carry ember and smoke damage. We inspect, photograph and write the repair estimate, while the policyholder or a licensed public adjuster deals with the insurer.
- Older Home Roof Replacement
Altadena's 1920s gabled houses and 1940s bungalows can carry spaced boards, stacked layers and old vents. We plan decking repair and ember-resistant detailing before the first shingle goes down.
- Roof Inspection
Altadena owners who are unsure whether fire, smoke or age is the problem can start with an inspection of vents, eaves, flashing and the attic, with photographs of what we find.
- Commercial Roof Replacement
