If the roof still has good years left, the report tells you.
Roof replacement and free written roof inspections across Glendale. Under the state’s 2025 maps, the city’s Very High Fire Hazard Severity Zone grew from roughly 8,973 parcels to about 16,383. The median Glendale home was built in 1966, and one in five dates from before 1940.
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 Glendale roof
Hills on two sides, period revival streets in between.
Newly inside the line
About 7,400 parcels joined the Very High zone with the 2025 maps. If yours is one of them, the next roof has to be a Class A assembly. The report states whether your address is in or out.
Tile on period revival homes
Rossmoyne, the city’s largest historic district, has 503 homes, many in Spanish Colonial and Tudor Revival styles. On a tile roof the tile usually outlasts the underlayment beneath it, and that layer is what we check.
Pre-war framing
One in five Glendale homes was built before 1940, according to the Census Bureau. On a house that age, the sheathing, the chimney flashing and past patch jobs tell us more than the surface does.
Before the rain in Glendale
Canyon streets, hillside lots and older homes in the flats.
Canyon streets
In Chevy Chase Canyon and on the streets below the Verdugos, runoff comes off the hill as well as the roof. Gutters and downspouts need to carry it well clear of the house.
Valleys on tile roofs
On period revival tile roofs, the metal valleys and the underlayment below them carry most of the water. That is where a long storm finds a tired roof.
Chimneys on pre-war homes
Brick chimneys on older homes often have flashing that has been patched more than once. We check it, along with the chimney crown, before the wet months.
Before the first big storm: book the free roof check, or read our winter storm roof guide.

The rules that apply to a Glendale roof
Glendale is its own city, with its own building officials and its own fire department.
Re-roofs are permitted by the City of Glendale, not by Los Angeles or the county.
In a historic district, roof repairs of 100 square feet or less in matching material count as routine maintenance. A change of roof material or form goes to the city to decide on design review.
Glendale Fire inspects parcels in the Very High zone annually, and a replacement roof there must be Class A.
We get on the roof, photograph what we find and write it up.

A roof in Rossmoyne or another Glendale district can need design review if the material or profile changes. The report records what is on the roof now, with dated photographs, so the conversation with the city starts from facts.

Roof questions in Glendale
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.
Did the 2025 maps put my house in the fire zone?
Possibly. The zone follows the Verdugos and the hills around Chevy Chase, and about 7,400 parcels were added in 2025. The report checks your address against the adopted map and says so in writing.
Know where your roof stands with the city.
A free written report with roof age, remaining life, fire zone status and any historic district notes. If a repair is the right call, the report says so.
“Mamos did a beautiful job renovating my new kitchen. They were patient, passionate, and attentive. They listened to my all of my personal preferences and installed beautiful new cabinets and granite countertops. Couldn’t be happier.”
