Roof Repair in Hidden Hills, from Association Review to City Permit
Roof repair in Hidden Hills takes place inside a gated city where the Hidden Hills Community Association, not the City, sets architectural standards, and where a full reroof also needs a City building permit. Fire rules count for more than they used to: CAL FIRE’s March 2025 map expanded the city’s Very High Fire Hazard Severity Zone from 305 acres to 748 acres, about 69% of the city.
Licensed, bonded and insured, CSLB #1119699
Hidden Hills incorporated on October 19, 1961, covers 1.69 square miles, and has just 738 housing units, all of them single-family homes or accessory dwelling units (ADUs). Here is what a reroof involves, from the Association’s review to the City’s inspections.
The City describes the split this way: HHCA oversees gate access, all infrastructure within the gates, and architectural standards, including architectural review, while the City handles building code enforcement and building and grading permits. The Association also owns and maintains nearly all of the streets, so plan crew and delivery access with HHCA before the tear-off date.
The City’s 2021-2029 Housing Element says nearly all projects need Association review, which the City does not control, and that projects with Association approval are exempt from City Site Plan Review. Eighteen sets of deed restrictions have been recorded since 1950, and the Association’s CC&Rs are designed to protect the community’s equestrian character. Ask HHCA for its current roofing standards, including allowed materials, colors, and review time, before you choose a product.
The Association’s sign-off normally comes first, because the City’s online Permit Center lists Homeowners Association (HOA) approval documents among the uploads for a permit application.
The City permit, run under contract by Transtech
Transtech provides building and safety and planning services under contract with the City, at City Hall, 6165 Spring Valley Road. The counter and phone line, (818) 888-9281, are open 9 to 11 a.m. on weekdays, and applications go through the City’s online Permit Center with plans, calculations, Title 24 documents, and soils reports as a project requires. When plans are reviewed, the Housing Element puts plan check at one to two weeks. Inspection requests are taken from 9 a.m. to 5 p.m. and must be made 24 hours ahead, and inspections happen after 11 a.m.
Hidden Hills is in inland climate zone 9, not the coastal zone 6 that covers Malibu. Under the 2025 Energy Code, replacing more than 50% of a residential roof in zone 9 triggers the rated cool roof requirement on both pitched and low-slope roofs, with some exceptions such as area-weighted alternatives. If the Association’s standards limit colors, check that the color you pick comes in a cool-rated version before you submit.
748 Very High acres on the 2025 map, up from 305
CAL FIRE’s March 24, 2025 map lists 748 acres of Hidden Hills as Very High, up from 305 acres on the 2011 map, plus 166 acres High and 99 acres Moderate. The city borders the Upper Las Virgenes Canyon Open Space Preserve. During the 2018 Woolsey Fire, LA County Fire listed Hidden Hills as both an incident location and a mandatory evacuation area, and in January 2025 the Kenneth Fire started in neighboring West Hills and burned 1,052 acres.
Most homes here were built long before the new map. The Census median year built is 1970, 63.4% of units predate 1980, and the community was laid out in the 1950s by landscape architect A. E. Hanson. The City’s residential plan checklist tells applicants to specify a minimum Class A roofing material on new construction plans, and we recommend Class A on every reroof in the Very High zone. Ask Building and Safety whether your parcel’s new mapping adds other requirements.
Two other checklist items matter if a reroof changes the roof’s shape or vents: finished ridge height may not exceed the plot-plan elevation and must be verified by a licensed surveyor, and attic ventilation must be at least 1/150 of the roof area.
Most parcels in Hidden Hills are at least one acre, under the General Plan’s RA-1 and RA-2 designations, so a main house and an ADU on the same lot may both need roof work. Overhead Roofing is a licensed roofing contractor (CSLB #1119699, C-39 Roofing), bonded and insured, and our team brings 25+ years of roofing experience. Our work here includes:
- Roof repair: leaks at valleys, chimneys, skylights, and roof-to-wall flashing, along with cracked or slipped tile and wind-lifted shingles.
- Roof replacement in Hidden Hills: tear-off, deck repair, and a new Class A, cool-rated roof, with product details ready for the Association submittal.
- Attic and ventilation checks: an attic inspection during a reroof to confirm the intake and exhaust vents are working.
- 24/7 emergency repair: tarping and temporary sealing, with fast response and same-day visits when crews are available.
Estimates are free, and our work carries a workmanship warranty. After storm or fire damage, we photograph the roof and write an estimate you can send to your insurer; we do not file or negotiate claims. Call (877) 557-7778.
HHCA approval, City permits, and cool roofs: Hidden Hills FAQ
Do I need Community Association approval before a roof replacement in Hidden Hills?
In most cases, you do. The City’s Housing Element says nearly all projects need Association review, and HHCA, not the City, sets architectural standards inside the gates. The City’s Permit Center lists HOA approval documents among the permit uploads, so get the Association’s sign-off first and ask for its current roofing standards before choosing a material or color.
Who issues the reroof permit in Hidden Hills?
The City of Hidden Hills does, through building and safety staff provided under contract by Transtech. Applications, including any HOA approval documents, go through the online Permit Center at hiddenhills.cts.city. For questions, the City Hall counter and phone line, (818) 888-9281, are open 9 to 11 a.m. on weekdays.
Is my Hidden Hills home in the Very High fire zone now?
There is a good chance it is. CAL FIRE’s March 24, 2025 map raised the city’s Very High acreage from 305 to 748 acres, about 69% of Hidden Hills, with another 166 acres mapped High and 99 acres Moderate. Look up your parcel on CAL FIRE’s map before ordering roofing, and plan on a Class A roof either way.
Does a new roof in Hidden Hills have to be a cool roof?
A full replacement usually does. Hidden Hills is in climate zone 9, where the 2025 Energy Code requires a rated cool roof when more than 50% of a residential roof is replaced, on pitched and low-slope roofs alike. Some exceptions apply, such as area-weighted alternatives. Pick a cool-rated product in a color the Association will accept, and include the Title 24 documents with the permit.
How far ahead does a roofer in Hidden Hills have to book inspections?
Inspection requests need at least 24 hours’ notice, and inspections happen after 11 a.m. On a reroof, we request each inspection the day before the crew reaches that stage, so an open roof does not sit waiting for the inspector. The Association’s review comes earlier, before the permit application goes in.
