Skylight Leak Repair in Coyote Hills from $350. Forty-year-old curbs, and the sealant that was never meant to last this long. Free inspection and a written quote.
Debris off the open ground collects on the upslope side of a skylight curb exactly the way it collects in a valley, and with the same result. A skylight that leaks only in heavy rain here is usually telling you the run above it is dammed rather than that the unit has failed.
Orange County tract housing from the 1960s through the 1980s is full of original skylights, and they are the single most common leak point we find in Fullerton. The unit itself is usually not the problem. The curb it sits on, the flashing around that curb, and the sealant bedding it are.



Re-flashing and re-bedding a skylight curb runs $350 to $1,200 depending on access and what the flashing is bedded into. Replacing the unit with a modern deck-mounted skylight and an integral flashing kit starts around $900 fitted and is frequently the better value on a forty-year-old curb. One cost specific to this edge of the city: if the parcel sits in a Very High Fire Hazard Severity Zone, a Chapter 7A Class A assembly adds roughly $1 to $5 per square foot, about 22%. Worth establishing before comparing two quotes that are not specifying the same roof.
A sound curb, sound framing and one failed face. That is a contained repair and it should be priced as one.
A site-built curb on a 1960s-80s tract roof, where another bead of sealant buys a couple of seasons and an integral kit buys decades.
Rotten opening framing, a shaft that has to be re-lined, or a tile roof where the surrounding field has to come up to reach the flashing.
Open ground on one side changes what lands on a roof. Wind-driven debris off the hills collects in valleys and behind chimneys, and the brush interface makes the fire-zone question worth asking rather than assuming -- inside a Very High Fire Hazard Severity Zone a re-roof is a Class A assembly under Chapter 7A. Check your own parcel on the state map; we will not tell you what it is.
Coyote Hills backs onto the nature park and the golf course, so debris load and brush exposure are ordinary considerations here rather than exceptional ones.
This is the most expensive mistake a homeowner makes in this market, and it is usually made on someone else's advice.
A skylight curb that has let go, a split upstand, a cracked vent boot: each is a repair costing hundreds, and each gets produced as evidence that the covering around it is finished. The two claims are not connected.
A tile roof quoted at $30,000 to $60,000 is very often an $8,000 to $22,000 lift and relay, because the tile is fine and only the felt beneath it has failed.
Sometimes the answer really is a replacement, and saying so is the same job as saying the opposite. What you should not accept is either answer without being shown why.
Backing onto open ground changes what lands on a roof.
Concrete tile and forty-year-old skylights.
Above the golf course. Wind finds the upslope face.
Big lots, old trees, and litter in every valley.
The newest stock here. Usually one failed detail.
1920s to 1970s on one street. Check the deck.
Oldest stock, parapets, and nowhere to park a truck.
A different city, with its own building department.
The questions this job turns on, answered up front.
Often not. The glass and the frame usually outlast the curb they sit on, and on a 1960s-80s Fullerton roof it is almost always the curb flashing and the sealant that failed. We price re-flashing and replacement side by side so you can see the difference.
A great deal. Water at the top corner of the shaft points at the head flashing; down one inside face points at that side of the curb; at the bottom edge often means the sill. It is one of the few roof leaks that can be narrowed down before anyone goes up.
Composition shingle, twenty to twenty-five years. Concrete tile, fifty or more -- but the felt underneath it, twenty to thirty, which is why tile roofs leak with the tile still perfect. Skylight sealant is the shortest-lived part of most roofs here at ten to fifteen years.
Because most online figures are national. Asphalt shingle is about $8.50 per square foot across this market against roughly $4 nationally. A quote that matches a national average is usually missing something -- most often the tear-off or the sheathing allowance.
Most land between $350 and $1,500, and small ones caught early start around $200. Orange County runs at or above the wider Los Angeles market. What moves it is whether the deck is already wet: a leak caught at the first stain is a flashing job, and one left for two winters is a carpentry job.
