As a roofing contractor in Fullerton, CA, we split our time between some of north Orange County's oldest homes and some of its newer hillside ones. The neighborhoods around the historic downtown and Hillcrest Park hold 1920s Spanish Revival houses under clay tile, while the north end climbs into the Coyote Hills. Fullerton is a city of 143,617 people and home to Cal State Fullerton and Fullerton College, and it sits about 21 miles, roughly 45 minutes, from our base on Rosemead Blvd. The same process we use for roofing in Rosemead applies here.
Clay tile on 1920s Spanish Revival homes near Harbor Blvd
Fullerton's older core, roughly the blocks near Harbor Blvd, Commonwealth Ave and Chapman Ave, has many Spanish Revival and Mediterranean homes with clay S-tile or barrel tile, flat roof sections behind parapets and stucco chimneys. The tile itself can last a very long time. The underlayment beneath it does not, and leaks on these houses usually trace to dried felt, cracked tiles at hips and ridges, or flat sections where parapet flashing has pulled loose.
George and Edward Amerige laid out Fullerton in 1887, and it incorporated on February 15, 1904, decades before most of the cities we serve. Valencia orange groves and the Brea-Olinda oil field drove its early growth, so the older core holds houses from the 1910s and 1920s, while groves farther out later became post-war tracts. A house that old has usually been reroofed several times, and a tear-off can uncover board sheathing, old flashing buried under newer layers and chimneys that have settled away from the roof.
If your house is a local landmark or sits in a designated historic area, ask the city's planning staff before changing roof material or color. Replacing clay tile with clay tile is usually the simplest path.
Repairs and reroofs from the Coyote Hills to Cal State Fullerton
North of the older neighborhoods, post-war tracts and later hillside homes carry composition shingle and concrete tile. Their common needs differ from the downtown blocks:
- Roof repair for leaks at valleys, flashing and skylights, plus lifted shingles after wind.
- Roof replacement when shingles are worn out across the roof or tile underlayment has failed throughout.
- Emergency roof repair for tarping when a branch or wind opens the roof during the November to March rains.
- Gutter and drainage work on hillside lots, where runoff from an upper roof can overwhelm the roof or yard below.
The West Coyote Hills ridge in north Fullerton holds some 510 acres described as the largest remaining undeveloped tract in north Orange County, and homes on the slopes around it face open ground and stronger wind. Cal State Fullerton, with its 26-acre Fullerton Arboretum, sits in the northeast, and Fullerton College is close to downtown. Downtown, the Fullerton Transportation Center serves Metrolink and Amtrak, and the surrounding commercial blocks carry flat roofs behind parapets, much like the flat sections on the older homes.
Roofing services for Fullerton, CA properties
Tile Roof Repair
Clay tile on Fullerton's 1920s Spanish Revival homes cracks at hips and ridges, and brittle century-old pieces need careful handling and matched salvage tile for replacements.
Tile Underlayment Replacement
Old clay tile near Harbor Blvd and Chapman Ave usually outlasts its felt, so the roof can be stripped, re-underlaid over sound or new decking and relaid with its original tile.
Roof Repair
Valley, flashing and skylight leaks are common on Fullerton's post-war tracts and hillside homes, along with shingle tabs lifted by Santa Ana wind events each fall and winter.
Roof Replacement
Worn shingle roofs on the tracts built over former orange groves need a full tear-off and deck inspection, and the new color may need to meet Title 24 cool-roof rules.
Emergency Roof Repair
Winter storms and branches from mature street trees can open a roof between November and March, and a tarp has to go on before the next band of rain arrives.
Flat Roofing
Small flat roofs behind stucco parapets on Spanish Revival homes drain through scuppers that clog, and water then backs up into walls unless the flashing and roofing are renewed.
Downspouts & Roof Drainage
On Coyote Hills lots, runoff from an upper roof or slope can overwhelm the roof and yard below, so downspouts and drainage get planned together with the roof itself.
Santa Ana wind and Title 24 choices for north Orange County roofs
Fullerton sits in the path of the Santa Ana winds that peak between October and March, and exposed ridges in the Coyote Hills take the strongest gusts. Wind lifts shingle tabs that have lost their seal and slides loose ridge tile, so we check fastening and ridge attachment on every inspection.
On a reroof that replaces half the roof or more, Title 24 cool-roof rules may apply depending on the climate zone, and the city confirms which ones. Clay and concrete tile heavy enough to weigh 25 lb/ft² are exempt, while a shingle roof may need a lighter, CRRC-rated color. We sort this out before you pick a product.

How does a roofer from Rosemead handle a Fullerton job?
We book Fullerton visits same-day or next-day when crews are free and plan the drive around traffic on the 60 and 57. On site, a roofer inspects the roof and attic, then you get labeled photos and a written quote with each item priced separately, including permits and any deck replacement. Fullerton is incorporated, so its building division handles reroof permits; confirm requirements with the city, and we file and schedule the inspection when one is needed.

Roofing questions from Fullerton
Can my original clay tile be reused on a Fullerton Spanish Revival home?
Usually much of it can. We remove the tile carefully, replace the underlayment and any damaged decking, and relay the sound tiles. Older clay tile can be brittle, so we plan for some breakage and look for salvaged or matching tile to fill in. The quote lists the expected replacement count.
Do flat roof sections behind parapets need special attention?
Yes. On many older Fullerton homes, small flat roofs sit behind stucco parapets and drain through a scupper. When the scupper clogs or the parapet flashing cracks, water backs up and finds its way into walls. We clear the drainage, reflash the parapet and replace the flat roofing if it is worn.
Is it worth repairing an older shingle roof in Fullerton, or should I replace it?
It depends on what the photos show. A single failed pipe boot or flashing joint on a roof with good shingles is worth repairing. If granules are gone across the roof, tabs crack when lifted or there are already two layers, the money is better spent on replacement, and we explain that reasoning in writing.
