CGI Roofing: The Orange County Owner’s Guide
If you have a CGI roof and a failed or failing part, the fix in Orange County typically runs $400 to $1,800 for repair work and $8,000 to $20,000 for a full replacement, depending on the component and the extent of the damage. We stock a range of CGI-compatible flashing, underlayment, and edge-metal parts, and in most cases we can match the exact profile on site. What usually brings an owner to this page is a leak at a valley or a cracked tile after a Santa Ana wind event, and the specific question is always the same: can this be matched, and what will it cost to make it right. The short answer is yes on both counts, and the price is in writing before we start.
CGI is one of the heavier concrete and stone-coated steel tile products on the Southern California market, and Orange County’s mix of coastal salt air in places like Huntington Beach and Corona del Mar, dry inland heat in Anaheim Hills and Yorba Linda, and the seasonal Santa Ana gusts in the canyons puts real stress on flashings, underlayment transitions, and the tiles themselves. Most failures we see are not the tile failing from age. They are the details around the tile: a cracked pipe boot, a valley metal that has separated at the seam, or a headwall flashing that pulled loose because the original install did not use the right gauge metal for the slope.
Key Takeaways:
- CGI parts failure in Orange County is most often a flashing or underlayment issue, not the tile itself.
- Installed repair pricing runs $400 to $1,800; full replacement runs $8,000 to $20,000.
- We match CGI profiles from manufacturer specs local suppliers keep on file for Orange County homes.
- Every price is written before work starts, and every completed job carries the 365-Day Done Right Promise.
Which CGI Models This Applies To

The compatibility question matters because CGI’s product line includes stone-coated steel profiles and concrete tile profiles that do not share flashings or battens. The most common CGI concrete profiles we work on across Orange County are the low-profile flat shingle and the higher-profile “S” shape, while the stone-coated steel lines use a different underlayment spec and a different fastening pattern altogether. The fastest way to identify what you have is to check the underside of a tile or the back of a ridge cap: CGI stamps the profile name and lot number there in most production years, and that stamp tells us everything we need.
If the stamp is faded or gone, we take a measurement: the flat profiles run roughly 13 by 17 inches at the exposure, while the “S” profiles can measure closer to 13 by 17 with a taller crown. We also check the batten spacing under the tile, because CGI concrete profiles on Orange County roofs from the late 1990s through the early 2010s were often installed at 13-inch exposures, which is tighter than the code minimum and affects which replacement battens and underlayment details are correct. Getting this wrong is the single most common reason a “matched” patch fails within two seasons: the replacement tile matches in color, but the exposure is off, and water tracks sideways under the profile.
One more compatibility point worth knowing: CGI stone-coated steel is not interchangeable with CGI concrete in the details, even when the color looks close. The ridge caps, hip caps, and closure strips are sized differently. We see this confusion on single-family remodels across Anaheim, Fullerton, and Santa Ana, and the fix is always the same: identify the exact profile, then source the correct CGI vented closure from the local distributor that supplies the Orange County market. We stock the common CGI concrete closures and a set of the stone-coated steel ridge hardware on the truck, and we can order the rest same-week. Bradford Remodeling Co Orange County is an independent service provider and is not affiliated with CGI, but we use their actual profile specs, not generic substitutes.

Signs Your CGI Roofing Is Failing
- Water staining at a valley or under a headwall. This is almost always a separated valley metal or a headwall flashing that has pulled off the wall. In Orange County, the high UV exposure degrades the sealant long before the metal itself goes, so the failure looks like a small dark line at the corner of a room.
- A run of tiles that shifts underfoot or rattles in wind. On concrete profiles this usually means the underlayment has degraded and the nails have lost their hold in the substrate. Santa Ana winds find the loose tile and start working it, and once one moves, the row above it starts to migrate.
- Granite or sand collecting in the gutters after a rain. Concrete tiles shed surface grit as they age, but a heavy accumulation in one corner of the gutter tells us a specific area of roof is breaking down faster, often near a valley where water concentrates.
- Rust streaks below a vent or pipe boot. The metal components fail before the tiles do. A rust streak on the roof or the fascia means the pipe boot or the vent flashing has corroded through, and the water is getting in behind the tile, not on top of it.
- Daylight visible from the attic through the roof plane. This is the most serious sign, and it usually shows up as a pinprick of light at a nail hole or a cracked tile. If you can see sky from the attic, you have a direct water path, and it needs to be addressed before the next rain.

AfterReplacement Cost & What’s Included

For Orange County homes, a targeted CGI repair, swap out a cracked tile, replace a pipe boot, re-secure a 10-foot run of valley metal, runs $400 to $1,800 installed. The spread depends on access: a one-story run in Irvine or a walkable low-slope section in Mission Viejo is faster and cheaper than a two-story cut-up in Anaheim Hills where the crew needs full fall protection and a tie-off point. Tile repair for concrete profiles runs $600 to $2,500 when multiple tiles and the underlayment beneath them need to come off and be rebuilt.
A full CGI roof replacement in Orange County runs $8,000 to $20,000, and the spread is driven by roof size, tear-off depth, the condition of the substrate, and whether we are doing a full tear-off or laying over existing felt that still has life in it. Every line on that number is written down: materials, labor, disposal, and the days the job will occupy. If the scope does not change, the number does not change. That is the Garrison Standard, and it applies to every Orange County roof we touch. All completed work carries the 365-Day Done Right Promise: if the repair or replacement fails inside a year, we come back and correct it at no charge.
For homeowners weighing a repair against a replacement, the honest read is this: if your CGI roof is under 20 years old and the failure is in the details, flashing, pipe boot, a few broken tiles, repair it. If the underlayment has failed across a large section and you are chasing leaks season after season, the per-year cost of patching starts to look worse than doing the roof once, correctly, with the full warranty in writing.
DIY or Call Us?
Some things are safe to check yourself. From the ground or a ladder, look for shifted tiles, rusted flashing, and cracks you can see without walking the roof. Clean the gutters and note where the granule accumulation is worst. Those observations help us price the job faster, and they cost you nothing. What you should not do is walk the roof and start lifting tiles. Tile roofs in Orange County see some of the highest foot-traffic damage of any roof type, from broken tiles to punctured underlayment. If you hear a tile crack underfoot, you have just created the leak you were trying to find. Working on a roof is inherently dangerous, especially on slopes, and the risk is not worth saving a service call.
What we recommend instead: call us at (562) 262-2907 and describe what you are seeing. We will ask a few questions, give you a straight price range over the phone, and set a time for one of our background-checked, uniformed technicians to come out and confirm the scope in writing. Straight number, clear scope, no surprises at final invoice.
FAQs

CGI concrete profiles in Orange County typically last 40 to 50 years on the tile itself, but the underlayment and flashings usually need attention between years 20 and 30. Coastal properties in Corona del Mar and Newport Beach may need flashing work sooner because of salt air. If your underlayment has failed, call us at (562) 262-2907 and we will give you an exact inspection read.
Yes, individual tiles can be replaced, and most of our Orange County CGI work is exactly that. The right fix is to remove the broken tile, inspect and repair the underlayment underneath, and set a matching profile in its place. If you are chasing multiple broken tiles after every wind season, call (562) 262-2907 and we will tell you whether replacement is the better use of your money.
A single-tile swap or pipe boot replacement usually takes one to two hours on site. A valley re-flash or a section of headwall work can take half a day, and a full Orange County roof replacement typically runs three to five working days depending on the roof size and tear-off depth. We will put the schedule in writing before we start.
We stock common CGI concrete closures, pipe boots, valley metal, and a set of stone-coated steel ridge hardware on the truck. For full-tile replacements in a discontinued color or profile, we source from the local CGI distributor that supplies the Orange County market, which usually takes under a week. Call (562) 262-2907 and tell us your profile, and we will confirm the lead time in one call.
