How old your roof really is, from permit records
How many years it has left, checked from the roof itself
Whether your address is in a fire hazard zone
Dated photos and notes, in writing for your insurance agent

If the roof still has good years left, the report tells you.

Roof repair, roof replacement and a free written roof inspection in Hidden Hills, for houses, condos, HOA and apartment buildings. Any roof change goes to the Architectural Committee before the city will issue a permit, and the association’s published standards limit which materials are on the table. Find out where your roof stands before you file anything.

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 look at in Hidden Hills

Approval first, permit second

The city will not issue a roof permit without the committee’s stamped approval, and the committee meets twice a month. The packet goes in before any material is ordered.

The 50 square foot rule

The association’s published standards say repairs that add up to more than 50 square feet in twelve months bring the whole roof up to the current standard. Patching can turn into replacing.

Big roofs, old houses

Over half of the city’s homes were built before 1970, on large lots. Pierce College, the nearest official station, recorded 121 degrees in September 2020.

Before the rain in Hidden Hills

Large tile and slate roofs, open hillsides and canyon wind.

Big roofs, many valleys

Large custom roofs have long valleys and many intersections. Valleys carry the most water in a storm and are where debris collects.

Wind before water

Santa Ana events across the open hills loosen ridge tiles and edges. The winter storms then work into whatever moved.

Drainage on large lots

With big roof areas, the volume of water in an atmospheric river is large. Gutters, downspouts and where they discharge deserve a real check.

Before the first big storm: book the free roof check, or read our winter storm roof guide.

What decides a Hidden Hills roof

From the association’s published architectural standards and the city. Ask for the current edition before you decide.

MATERIALS
Class A only

Faux wood shake, slate, faux slate and two-piece clay tile are the listed primary materials. Composition shingle and wood shake are not on the list.

APPROVAL
Committee first

The Architectural Committee meets on the first and third Monday. No stamped approval, no city permit.

FIRE ZONE
Mixed

The state’s 2025 map puts parts of the city in Moderate, High and Very High zones. The report tells you which applies to your lot.

We get on the roof, photograph what we find and write it up.

Roof questions in Hidden Hills

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.

Can I re-roof without the Architectural Committee?

No. The city will not issue a permit without the committee’s stamped approval, so approval comes first. Our report tells you what condition the roof is really in, which decides whether you are asking for a repair or a replacement.

Know what the roof needs before you go to the committee.

The report gives you the roof’s age, remaining life and the fire zone answer in writing, so the request you make to the association is for the right job.

“Joseph was very clear about the process, the costs, the recommendations. … His team was very professional, on time, fast, and respectful, but most importantly, they were good!”
