Skylight Leak Repair in Sunny Hills from $350. Forty-year-old curbs, and the sealant that was never meant to last this long. Free inspection and a written quote.
Under a mature canopy the skylight problem is debris rather than sun. Leaf litter builds against the upslope side of the curb, holds water there permanently, and rots the flashing from above while the sealant elsewhere on the same unit is still sound. Clearing above the curb is genuinely preventative here.
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. Tree work is a real line here and it is not padding. Limbs that need protecting or trimming, and whether a conveyor can reach the roof at all, both change the price. So does the extra outlet capacity a canopy-loaded roof genuinely needs.
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.
The trees are the roofing story. Mature canopy over a roof means leaf litter in the valleys and gutters holding water against the covering long after the rain stops, and limbs abrading the surface every time the wind gets up. On tile that debris packs under the courses and rots the felt while the tile above still looks new.
Sunny Hills is one of the city's oldest established neighborhoods, on larger lots under a mature canopy that most of Fullerton does not have.
Including ours. There are enough door-knockers working this county that the checks are worth making on anybody.
Roofing in California is C-39 work. The number is public, the CSLB register answers in under a minute, and the check is worth making on anybody who knocks -- including us.
A fire-rated assembly, a tear-off versus an overlay, and a sheathing allowance each move the price by thousands. A cheaper quote is sometimes a lesser roof rather than a better price.
A number produced in the driveway is a guess with a decimal point on it. Nobody can price a skylight curb, a valley or a wall flashing without getting to it, or judge the ceiling below without looking at it. We do not price at the curb and we do not price from a photograph you send us.
Under this much mature canopy the leak is nearly always organic.
Concrete tile and forty-year-old skylights.
Above the golf course. Wind finds the upslope face.
The newest stock here. Usually one failed detail.
1920s to 1970s on one street. Check the deck.
Backs onto the park. Debris and brush exposure.
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.
No, but it is a useful symptom. A roof that only leaks in driving rain is usually failing at an upstand, a skylight curb or a lap that is perfectly watertight under vertical water. That narrows the search a long way before anyone gets on the roof, so it is worth telling us.
Sometimes, and it is often a false economy. Roofing work in California requires a CSLB C-39 license above a small dollar threshold, and the reason most leaks get fixed twice is that the first attempt sealed the stain rather than the entry point. Ask whoever you use how they intend to find it.
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.
