What the survey says about San Diego
Nothing for San Diego itself. San Diego homes are in the Census Bureau's housing survey, but its public data doesn't show the San Diego area on its own. In the five Pacific states, owners paid a median of $15,000 for a new roof (jobs from 2021 to mid-2023). That is a whole region, not San Diego.

San Diego roof permits
In San Diego, a plain roof re-covering on a home doesn't need a permit. So most roof jobs never show up in city records, and we don't use the few that do. This page has no San Diego permit numbers — only the city's rules and homeowner reports.
When San Diego does need a permit
You need one when the deck or roof structure is replaced, when switching to a much heavier roof such as tile (over 6 lb per sq ft), when replacing spaced boards with solid sheathing, or on any historic building. Source: City of San Diego, Information Bulletin 123 ↗
The permit fee barely depends on the job price: the city charges for plan review by the hour, plus a flat inspection fee of $264.25 for re-sheathing a house and some other set fees. Source: City of San Diego, Information Bulletin 501 ↗

What the numbers say about San Diego roof costs
Questions people ask, answered from City of San Diego rules, NOAA's storm records and the Census survey for the region.
Why are there so few San Diego numbers?
Two reasons. The Census Bureau's public survey data doesn't show the San Diego area on its own. And most roof jobs in San Diego need no permit, so they leave no public record. Homeowner reports are the only way to fill this in.

Do I need a permit for a new roof in San Diego?
Usually not. Replacing the covering like for like needs no permit. The deck, a heavier roof (tile), replacing spaced boards, or a historic home — those do.

Is hail a problem in San Diego?

What can't this page tell you about San Diego yet?
A typical price, roof size and roof material. Homeowner reports will fill this in.
Why: no separate survey numbers and few permits
Questions people ask
Is $30,000 too much for a roof?
We don't have a San Diego number yet. In the five Pacific states, owners paid a median of $15,000 for a new roof (jobs from 2021 to mid-2023), so $30,000 is about twice that. But that's a whole region, not San Diego. Tile, a bigger roof, or new deck boards push the price up. Add your estimate to start San Diego's own number.
Will insurance cover a 20-year-old roof in California?
We can't tell. It depends on your policy and on what damaged the roof, so ask your insurer before you sign an estimate. In the survey for the five Pacific states, only a few new roofs were paid mainly by insurance, too few for a reliable share.
What is the 25% rule for roofing?
In San Diego, it's a permit exemption: on a house, duplex or townhouse, you can replace damaged deck boards with the same kind without a permit, as long as it's no more than 25% of the roof surface. Source: City of San Diego, Information Bulletin 123 ↗. In some other states, like Florida, the "25% rule" means something else. There, if more than 25% of a roof section is repaired or replaced within 12 months, the whole section may have to meet today's building code. Since 2022, Florida applies this only to older roofs, not to roofs built to the 2007 code or later. Source: J.S. Held, "Florida Building Code 25% rule" ↗
How much does a 1500 sq ft roof cost in California?
We can't say by roof size for San Diego yet. In the five Pacific states, owners of homes from 1,500 to 2,499 sq ft paid a median of $15,000, and of smaller homes $12,000 (jobs from 2021 to mid-2023). That's the size of the house, not the roof, and a whole region, not San Diego. Homeowner reports will fill this in.
How much does a new roof cost in San Diego?
We don't have a San Diego number yet. In the five Pacific states, owners paid a median of $15,000 for a new roof (jobs from 2021 to mid-2023), but that is a whole region, not San Diego. Add your estimate or bill to start San Diego's own number.
Do I need a permit to replace a roof in San Diego?
Usually not. A plain re-covering needs no permit. You need one when the deck or roof structure is replaced, when switching to a roof heavier than 6 lb per sq ft (like tile), when replacing spaced boards with solid sheathing, or on a historic building. Source: City of San Diego, Information Bulletin 123 ↗
Why doesn't this page use San Diego's permit data?
Two reasons: most roof jobs need no permit, so the data covers only a few special cases (historic homes, new decks); and the city's data terms ask users to take on legal costs for the city, which we don't accept. We only show what we can stand behind.
Where do these numbers come from?
For San Diego, only reports from homeowners like you. The region number is from the American Housing Survey 2023 (U.S. Census Bureau and HUD). We review every homeowner report before it shows.
Why do cost guides show a lower number?
Most cost guides give one average for a typical shingle roof, worked out from national prices or from their own customers, then adjusted for your area. They rarely say how many jobs are behind the number or which years it covers. We show the government survey number for the five Pacific states, marked as a region, and what San Diego homeowners report, with the count of jobs behind each number. A bigger roof, a flat roof, or rotten deck boards push a real job well above a guide's average.
