Roofing in Corona, CA: Repairs and Reroofs on 1980s and 1990s Homes
Roofing in Corona, CA, often means working on houses from one building boom: 25,564 of the city’s 50,799 homes went up between 1980 and 1999, and the median home dates to 1991. Overhead Roofing handles reroofing and roof repair projects in Corona, with inspection visits scheduled directly with property owners in advance.
Licensed, bonded and insured, CSLB #1119699
Two other conditions shape the work: Santa Ana winds in the Santa Ana River canyon, and a 2025 fire map that extends wildfire building rules into High zones.
Half of Corona's homes went up between 1980 and 1999
Census Bureau estimates (ACS 2020 to 2024) show how much of Corona went up in two decades: 12,150 homes in the 1980s and 13,414 in the 1990s, or 50.3% of all housing. Most units (65.6%) are single-family detached, and 20.6% are in buildings of five or more units, where the owner or association decides on the roof.

House age and roof age can differ, since some homes have been reroofed. Where an older roof is still on, the layers under the covering usually decide the job. Underlayment, flashing at walls and valleys, and pipe-vent boots wear out first, and a leak often starts there while the tile or shingles still look sound.
So roof repair in Corona, CA, on a 1990s house starts with those layers. A tile roof can sometimes be relaid, with sound tile reused over new underlayment and flashing. A shingle roof that age is usually replaced in full, as our reroofing page explains.
Santa Ana winds in the river canyon and Ordinance 3418
Corona’s Local Hazard Mitigation Plan describes Santa Ana, or foehn, winds of 40 to 50 miles per hour that move from the eastern deserts into the Santa Ana River canyon, often with temperatures above 90 degrees and humidity of 20% or less. Those gusts work on a roof’s edges first: shingle tabs at eaves and rakes, ridge and hip pieces, and perimeter tile. The dry heat also hardens sealant at vents and flashing.
Wind carries embers, too. Through Ordinance 3418 (Municipal Code section 15.16.010), Corona adopted the State Fire Marshal’s map dated March 24, 2025, as published, with Moderate, High, and Very High zones. Corona Fire says the wildland standards in California Building Code Chapter 7A, once limited to the Very High zone, now apply in the High zone as well.
Corona Fire counts about 3,000 structures in the Very High zone and just over 14,000 more within half a mile of it. The City’s hazard plan places the wildfire-prone edges at the Santa Ana River Canyon along SR-91, the Prado Basin, the Corona Hills, Eagle Valley, and the Cleveland National Forest boundary. Chapter 7A calls for ignition-resistant construction, including a Class A roof, so we check each address on the City’s map first.
Permits, scope, and scheduling for roofing in Corona, CA
Reroof permits come from the City of Corona Building Division at 400 S. Vicentia Ave., Suite 120, open Monday through Thursday, 7 a.m. to 6 p.m., and closed Fridays. Applications, inspection requests, and permit history go through the City’s eTRAKiT portal.
Corona is in Climate Zone 10. Once a reroof replaces more than half of a home’s roof, the 2025 California Energy Code (in force since January 1, 2026) requires a cool roof: a product rated by the Cool Roof Rating Council (CRRC) on steep-slope roofs, with a separate path for low-slope roofs. Repairs below that line don’t trigger it, so our estimates give the share of the roof being replaced.
The Corona work we take on:
- Repairs: wind-lifted shingles, cracked or slipped tile, worn flashing, and split vent boots
- Tile relays: new underlayment and flashing beneath tile that can be reused
- Full reroofs: tear-off to the deck, decking repairs, and a Class A, CRRC-rated covering where the rules call for one
- Low-slope roofs: patio covers, additions, and apartment buildings

Corona roof questions on permits, fire zones, and 1990s roofs
Is the Corona Building Division open on Fridays for reroof permits?
No. The Building Division at 400 S. Vicentia Ave., Suite 120, is open Monday through Thursday from 7 a.m. to 6 p.m. and closed Fridays. You can still apply, request inspections, and check permit history online through eTRAKiT. The division’s phone number is 951-736-2250.
My Corona house is in a High fire zone. Do the wildfire rules apply to a reroof?
Under the 2025 map, yes. Corona adopted the State Fire Marshal’s map by Ordinance 3418, and Corona Fire says the Chapter 7A wildland building standards that once covered only Very High zones now cover High zones too. Those standards include a Class A roof, so check your address on the City’s map before choosing a covering.
What should a roofing contractor in Corona, CA, check on a 1990s roof?
Start with what sits under the covering. On a 1990s house, original underlayment, flashing, and vent boots can be 27 to 36 years old even when the tile or shingles look fine. The inspection should also cover eaves and ridges that take the canyon winds, the deck as seen from the attic, and how much of the roof needs work, since replacing over half brings in the Zone 10 cool roof rule.
Should I check my Corona roof after a Santa Ana wind event?
Yes, and you can start from the ground. The City’s hazard plan describes 40 to 50 mph Santa Ana winds moving into the Santa Ana River canyon, often with heat above 90 degrees. Look for lifted or missing shingle tabs, loose ridge pieces, and tile out of line at the edges. If you see any, book an inspection before the rainy season.
