If the roof still has good years left, the report tells you.
Roof replacement and free written roof inspections across Canoga Park. In ZIP code 91303 the 1950s built more homes than any other decade, yet one in three homes there dates from 2000 or later, according to the Census Bureau. A post-war ranch house and a building from the 2010s need different things from a roof.
Deck, underlayment, then shingles or tile. The underlayment keeps the water out, and you can only check it from up on the roof.
What we check on a Canoga Park roof
The age of the house decides most of the list.
Shallow attics on ranch houses
Low-pitched post-war houses have tight attics that trap summer heat and wear shingles from below. We check the vents and the airflow along with the roof covering itself.
The wood roof rule is citywide
Canoga Park sits mostly on the flat valley floor, but the 1989 city roofing ordinance applies everywhere in Los Angeles. Replace more than 10 percent of a wood roof in a year and the whole roof has to change to an approved material.
Newer roofs reaching their first re-roof
Homes built in the 2000s are coming up on the age when the original roof needs a decision. The report records flashing, vents and wear on each slope, so you know whether that time is now or later.
Before the rain in Canoga Park
The Los Angeles River starts here, behind Canoga Park High School. Storm water from the west end of the Valley runs past.
Where two creeks meet
Bell Creek from the Simi Hills and Arroyo Calabasas from the Santa Monica Mountains join here to form the Los Angeles River. In a long storm a lot of water moves through, so downspouts that empty against a foundation are worth fixing before it arrives.
Old vent boots
The rubber collars around plumbing vents dry out and crack in the Valley sun. They are a small part, and a common first leak of the season.
Garage and carport roofs
Detached garages and carports often have a low-slope roof that nobody looks at. Water that sits there finds every seam.

What the city requires on a Canoga Park roof
Owensmouth joined Los Angeles in 1917, so city permits and city fire rules apply here.
A re-roof needs a permit from the Los Angeles Department of Building and Safety, the same office that permits the rest of the Valley.
The 10 percent rule applies on the flats too. Past that point in a twelve month period the whole roof must conform, and wood shake or shingle cannot go back on.
When more than half the roof is replaced, the city calls for CRRC rated cool roof products. The report notes which options suit your roof.
We get on the roof, photograph what we find and write it up.

Plenty of post-war Canoga Park houses got their current roof decades ago. A free inspection tells you, in writing, whether it has real years left or is near the end, with dated photographs of each slope.

Roof questions in Canoga Park
Repair or replace?
Usually the underlayment decides it, and you have to get on the roof to check that. The report gives you the answer, with photos.
What does a new roof change for my insurer?
Most letters name roof age. The permit and completion papers show the new roof’s date; what the carrier does with them is its decision.
Is Canoga Park in a fire hazard zone?
Most of it is not. LAFD does not list Canoga Park among its Very High zone communities, but the state issued new maps in 2025 and the line runs parcel by parcel, so the report confirms your address in writing.
