Cracked sealant around the skylight curb
We strip the old sealant, clean the curb, and reseal with UV-rated polyurethane. If the curb itself is cracked, we rebuild it and reset the skylight so the seal has a solid base.

About this service
What Skylight Leak Repair Whittier CA Actually Involves
Skylight Leak Repair Whittier CA is the trade of finding and sealing the exact point where water gets past a skylight assembly, then restoring the roof around it so the leak does not return. Most skylights do not fail in the glass. They fail at the curb, the flashing, or the sealant bead that has baked in the sun for years. We open the assembly, inspect the framing, and rebuild the waterproofing layer by layer.
Whittier sits in Los Angeles County where summer heat pushes past 100 degrees and winter rain arrives in short, heavy bursts. That swing cracks old sealant and pulls flashing away from the curb. If you have watched a ceiling water stain grow after a storm, you are looking at flashing failure, not a bad pane. We also handle skylight sealing Whittier homeowners call about after the first rain, and we can usually get there the same day.

What's included
What Our Skylight Leak Repair Service Includes
Every skylight leak repair starts with a full inspection and water test, then moves into the repair itself. Here is what is covered on a standard Whittier job and what we handle as an add-on when the damage goes deeper.
✓
Full Leak Inspection
Roof-side inspection of the skylight curb, flashing, and surrounding roof, plus an attic check with a moisture meter and infrared thermal camera. We confirm the skylight is the source before quoting the repair.
✓
Controlled Water Test
We run a staged hose test over the skylight to reproduce the leak and pinpoint the entry. This is how we avoid sealing the wrong spot and having you call back next rain.
✓
Flashing and Sealant Repair
Removal of failed sealant and damaged flashing, replacement with new flashing bent to fit, and sealing with Tremco or Sika polyurethane rated for Southern California UV and heat.
✓
Underlayment Replacement
Where the underlayment around the skylight has failed, we cut it back and install new Grace or equivalent underlayment so the waterproofing layer is continuous again.
✓
Final Water Test and Cleanup
A second water test confirms the repair holds, and we clear the roof and gutter line of debris. You get a written summary of the failure and the fix, plus warranty paperwork.
How it works
How Our Skylight Leak Repair Process Works
01
Phone Intake
You call (562) 443-3829 and describe what you are seeing: where the drip lands, when it started, and whether it follows a storm. We ask about your skylight type and roof material so the right tech and parts show up. Most Whittier calls get a same-day or next-morning window.
02
Roof and Attic Inspection
We climb the roof ladder and inspect the skylight curb, flashing, and surrounding shingles or tile. Inside, we check the attic decking with a moisture meter and scan the ceiling with an infrared thermal camera. This takes 30 to 45 minutes and tells us exactly where water is entering.
03
Water Test
We run a controlled hose test over the skylight in stages, starting low and working up. If water shows up inside, we know the entry point is confirmed. If it does not, we keep testing the flashing and curb until we reproduce the leak. No guessing, no sealing blind.
04
Repair and Reseal
We remove failed sealant, replace damaged flashing or underlayment, and reset the skylight with fresh sealant and a skylight seal kit where needed. On tile roofs we lift and reset the surrounding tile. This stage usually runs two to four hours depending on access and damage.
05
Final Test and Cleanup
We re-run the water test to confirm the leak is gone, then clear the roof of debris and check your ceiling for any new moisture. You get a written summary of what failed, what we fixed, and what to watch. If the skylight needs replacement instead of repair, we tell you straight.
Tools & methods
Tools and Methods We Use on Skylight Leaks
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Moisture Meter
Reads water content in sheathing, drywall, and framing so we can confirm the leak source and check how far moisture has spread.
Infrared Thermal Camera
Shows temperature differences from evaporating moisture, letting us trace hidden water paths across a ceiling without cutting into drywall.
Flashing Bender
Forms new metal flashing to match your skylight curb and roof pitch, so the repair fits the assembly instead of being forced into place.
Caulking Gun and Skylight Seal Kit
Applies controlled beads of Tremco or Sika sealant and installs manufacturer seal kits for a clean, uniform waterproofing layer.
Roof Ladder and Fall Protection
Gets our OSHA-certified techs safely onto tile, shingle, and flat roofs, including steep Whittier pitches and two-story homes.
Drone for Roof Inspection
Captures high-resolution images of hard-to-reach skylights and roof sections so we can document conditions before and after the repair.
Real results
Before and after.
Uptown Whittier Skylight Flashing Rebuild
Before
A 1970s tile roof skylight leaked every winter for three years. Previous handymen had smeared roof cement around the frame, which cracked within months. The ceiling stain had spread to roughly two square feet and the sheathing read wet on the moisture meter.
After
We lifted the surrounding tile, replaced the failed flashing and underlayment, and reset the skylight with new sealant. A staged water test held dry. The attic decking read normal moisture within a week, and the leak has not returned through two rainy seasons.
Friendly Hills Emergency Storm Leak
Before
A homeowner called during a February storm with water pouring through a skylight onto a hardwood floor. The ceiling was bulging and the bucket was filling every 20 minutes. We dispatched a crew within two hours of the call.
After
We tarped the skylight that night to stop the water, then returned the next morning to replace the flashing and reseal the assembly. Total repair time was about three hours. The floor dried without warping and the ceiling was patched and painted.
East Whittier Shingle Roof Skylight Reseal
Before
An asphalt shingle roof skylight leaked a small but steady drip after every rain. The homeowner had searched for affordable skylight repair near me Whittier and tried a hardware-store sealant, which failed in one summer. The sealant around the curb was cracked and lifting.
After
We stripped the failed sealant, replaced the damaged shingles around the skylight, and installed new flashing and a skylight seal kit. The final water test held dry. The repair came in under $600 and carries a workmanship warranty.
Problems we solve
Skylight Leak Problems We Solve in Whittier
Most skylight leaks trace back to one of a handful of failures. Here are the ones we see most often on Whittier roofs, and what happens if you let them ride.
Ask a pro →↗
Flashing pulled away from the skylight
We remove the failed flashing, bend new flashing to fit the curb, and tie it into the surrounding roof plane. Fasteners are set and sealed so the flashing cannot lift again.
Failed underlayment under tile or shingle
We lift the surrounding tile or shingles, replace the failed underlayment with new material, and reset the covering. The skylight flashing ties into the new underlayment so the whole assembly drains correctly.
Condensation mistaken for a leak
Our moisture meter and thermal camera readings tell the difference between a roof leak and condensation. If it is humidity, we tell you straight and point you to ventilation fixes instead of charging for roof work.
Transparent pricing
What Skylight Leak Repair Costs in Whittier
$350 - $950 depending on scope
Typical 2026 pricing for skylight leak repair in Whittier runs $350 to $950, with most single-skylight repairs landing between $450 and $700. The price depends on roof access, tile versus shingle, and whether the flashing or the skylight itself failed. A simple reseal costs less. A full curb rebuild or skylight replacement costs more. We inspect first, water-test the leak, and quote the repair before we start. No hidden add-ons, no pressure to replace a skylight that only needs new flashing.
Paying for a proper repair once beats patching the same leak every season. Our work carries a workmanship warranty, and we use materials rated for Whittier heat and UV so the fix lasts.
01Roof type and access
Tile roofs take longer because surrounding tile must be lifted and reset without cracking. Steep pitches and two-story homes also add labor time. Shingle roofs with easy access sit at the lower end of the range.
02Extent of flashing damage
A cracked sealant bead is a quick fix. Flashing that has pulled away or rusted through requires new metal formed to fit the curb, which adds material and labor. This is the single biggest price driver.
03Underlayment condition
If the underlayment around the skylight has failed, we cut it back and replace it. That means lifting more of the roof covering and adds time. Skipping it would just move the leak a few feet over.
04Skylight condition
Most skylights can be repaired. If the frame, glass, or curb is cracked beyond sealing, replacement is the honest answer. We tell you which one you are looking at before quoting.

Reviews From Whittier Skylight Repairs
★★★★★
“Water was dripping through our skylight every time it rained and the ceiling stain kept getting bigger. The crew found the flashing had pulled away from the curb and rebuilt it the same visit. They water-tested it twice before leaving. Two storms later, still dry. Fair price and no upsell on a new skylight.”

“Our tile roof skylight had been leaking for months and two other guys just smeared caulk on it. These techs lifted the tile, replaced the underlayment, and reset the flashing properly. Took about four hours. They showed me photos of the failed sealant and explained everything. Worth every dollar.”

“Called on a Sunday during a storm and they actually picked up. Tech arrived a couple hours later, tarped the area, and came back Monday to do the repair. The moisture meter found the leak was at the skylight and not the chimney like I thought. Honest diagnosis and a written warranty.”

Priya S.Homeowner, East Whittier
✓ VerifiedMost skylight leak repairs in Whittier run $350 to $950 in 2026, depending on roof access, tile versus shingle, and whether the flashing or the skylight itself failed. A simple reseal and flashing repair sits at the low end. Full curb rebuild or skylight replacement pushes higher. We quote before we start, and the inspection is free.
The sealant or flashing around the skylight curb has failed, not usually the glass. Whittier summers bake sealant past 100 degrees, then winter rain finds the crack. Flashing failure, loose fasteners, and cracked curb sealant cause most leaks we see. A moisture meter and water test confirm the exact entry point before we repair anything.
Yes, if the skylight is the source. We water-test the skylight first, and if the ceiling stain tracks back to it, sealing the flashing and curb stops the drip. If the water is coming from a chimney, valley, or pipe boot instead, we find that too. One visit, one diagnosis, one repair plan.
We do, and we are local to Whittier. Our crews cover Uptown, Friendly Hills, East Whittier, and surrounding areas like La Mirada and Santa Fe Springs. Call (562) 443-3829 and we will schedule an inspection, usually same day for active leaks. You get a licensed, insured crew and a written workmanship warranty.
