Roof repair, roof replacement and a free written roof inspection in Simi Valley, for houses, condos, HOA and apartment buildings. Two in three homes in ZIP codes 93063 and 93065 went up between 1960 and 1989, according to the Census Bureau. Many of those roofs are on their second or third covering.
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 Simi Valley roof
Tract houses from three decades, with the hills on every side.
Layers and decking
A tract house from the seventies has usually been re-roofed once. We check whether an older layer was left in place and what shape the sheathing is in under it.
Flashing and vents
Chimney, wall and vent flashing is often older than the shingles around it. Cracked vent boots and lifted flashing are the usual first leaks.
Ember entry points near the hills
The Easy Fire started at the west end of the city in 2019. On hillside streets the report notes open vents, gaps at the eaves and debris in the gutters.
Before the rain in Simi Valley
Tract roofs from the sixties to the eighties, and hillside lots that shed water fast.
Vent boots and flashing
The rubber collars around plumbing vents crack after years of valley sun. They are a small part and a common first leak of the season.
Gutters below the hills
Lots near the open space collect leaves, grit and ash. A full gutter backs rain up under the roof edge in the first long storm.
Low-slope patio and garage roofs
Patio covers and garage additions often run at a shallow pitch. Water sits longer there, so we check them with the main roof.
Before the first big storm: book the free roof check, or read our winter storm roof guide.

Roof questions in Simi Valley
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 my Simi Valley house in a fire hazard zone?
Parts of the city along the hills are, and the line runs parcel by parcel. The state issued new maps in 2025, so the report states your address’s status in writing.
