Flashing, Skylight & Chimney Leak Repair in California starts with finding the exact entry point, not guessing. We handle chimney leak repair, skylight flashing repair, and vent pipe leak repair for homeowners, property managers, and commercial buildings from the coast to the Central Valley. When rain hits and water shows up on your ceiling, we get a tarp on it and a permanent fix scheduled fast.
Flashing, Skylight & Chimney Leak Repair in California means sealing the joints where your roof meets something that isn't shingle: chimneys, skylights, vent pipes, and sidewalls. Those transitions rely on metal flashing, roofing underlayment, and sealant to shed water. When the metal rusts, lifts, or was installed without proper step flashing, water runs straight into the attic. We remove the failed material, rebuild the layers, and set new flashing so the roof drains the way it should.
California roofs take a beating from both ends: dry, baking summers that crack sealant, then winter storms that push water sideways under lifted metal. That cycle is why skylight leaking when it rains is so common here. If you need skylight leak repair services in California, we start with a moisture meter and infrared camera scan to confirm the path, then repair the flashing, not just the stain on your ceiling.
Every job starts with a full leak inspection and ends with a water test and written warranty. The scope below covers standard repairs. If we find rotted decking or a failed skylight unit, we will show you and price it before we proceed.
We inspect the chimney, skylight, vent pipes, and all flashing transitions using a moisture meter and infrared camera. You get a written report with photos showing the entry point and the water path. This step takes 30 to 45 minutes.
We remove failed step flashing, counter-flashing, and sealant, then install new metal with proper overlap. Materials are matched to your roof type, whether asphalt shingles, tiles, or a flat membrane. This is the core of the repair.
New roofing underlayment goes under the flashing, and we seal all joints with Henry Company roof cement or a compatible sealant. We do not rely on caulk alone. The layers work together to shed water.
Before we leave, we run water over the repaired area and re-scan with the moisture meter. If any moisture shows up, we keep working. You see the test results and get photos of the finished repair.
We haul away all old flashing, sealant tubes, and debris. You receive a written two-year workmanship warranty and a photo record of the repair. That documentation helps with insurance claims and future home sales.
You call (877) 299-0450 and describe what you see: a stain, a drip, a wet chimney chase. We ask the right questions to gauge urgency and dispatch a technician, usually within hours for active leaks. If water is flowing, we walk you through shutting off the source.
A technician inspects the chimney, skylight, and vent penetrations using a moisture meter and infrared camera. We check flashing seams, step flashing, counter-flashing, and sealant joints. You get a written scope with photos before any work starts, so you know exactly what we found.
If rain is in the forecast, we tarp the affected area right away. That stops further water intrusion and protects your interior while we stage materials. Tarps stay in place until the permanent repair is complete, and we remove them on the final visit.
We remove failed flashing, underlayment, and sealant, then rebuild the detail with new metal, roofing underlayment, and code-compliant materials. Depending on scope, this takes two to six hours. We use a roofing nail gun, pry bar, and caulking gun to set everything cleanly.
Before we leave, we run a water test over the repaired area and re-scan with the moisture meter. You get a written warranty and photos of the finished work. We haul away all debris and leave your roof and gutters clean.

Detects temperature differences caused by moisture behind drywall and sheathing. We use it to trace the water path before we open anything up, so we repair the actual entry point.
Confirms the presence and extent of moisture in framing, decking, and insulation. We take readings before and after the repair to prove the leak is sealed.
Fastens new flashing, underlayment, and shingles securely. We adjust pressure to avoid over-driving nails, which can create new leak points.
Removes old flashing and sealant without damaging surrounding shingles or tiles. Clean removal is the first step to a lasting repair.
Applies Henry Company roof cement and compatible sealants in controlled beads. We use the right sealant for the material, not a one-size-fits-all caulk.
Keeps our technicians safe on steep pitches and wet surfaces. OSHA-compliant tie-offs are standard on every job.
A homeowner had a recurring ceiling stain for two years. Two roofers had patched the shingles with no result. The chimney step flashing was rusted through, and water was running down the chase into the attic.
After: We removed the old flashing, replaced a 3-foot section of rotted sheathing, and installed new step and counter-flashing. A water test showed no leaks. The ceiling stain stopped spreading, and the repair passed a follow-up moisture check.

A commercial building had water dripping from a skylight onto office equipment every time it rained. The building owner assumed the skylight needed replacement. The actual problem was failed flashing at the curb.
After: We rebuilt the skylight flashing and resealed the curb with Henry Company sealant. The repair took four hours. A water test confirmed no leaks, and the owner avoided a $3,500 skylight replacement.

After a windstorm, a homeowner noticed water dripping around a vent pipe in the attic. The rubber boot was cracked and the flashing collar had lifted. The leak was small but constant during rain.
After: We replaced the vent boot with a UV-rated unit and resealed the flashing collar. The repair took under two hours. A moisture meter reading confirmed the attic framing was dry, and the leak has not returned.

We inspect the skylight flashing, curb, and sealant. Most repairs involve rebuilding the flashing and resealing the curb. If the unit itself has failed, we tell you and price a replacement separately.
We remove the old flashing, repair any rotted wood, and install new step and counter-flashing with proper overlap. We also seal the chimney chase and crown if needed. The repair is water-tested before we leave.
We replace the boot with a new, UV-rated unit and reseal the flashing collar. This is a fast repair, usually under two hours, and it stops the leak immediately. We check all other penetrations while we are on the roof.
Most skylight leak repairs run $350 to $900 in 2026, depending on access, roof pitch, and whether the flashing or the skylight unit itself has failed. A simple flashing reseal is on the low end. Replacing the skylight or rebuilding the curb pushes it higher. We give you a written scope with the price before we start.
You fix it by removing the old flashing, repairing any rusted or rotted step flashing, and installing new metal with proper overlap and sealant. Caulk alone will not hold. We also check the counter-flashing and chimney chase for cracks. The repair usually takes three to five hours and includes a water test.
Skylight leaking when it rains in California is almost always a flashing or seal failure, not the glass. UV exposure cracks the sealant, and thermal expansion lifts the metal over time. Debris and pine needles can also dam water at the curb. We inspect the flashing, curb, and unit, then repair the actual failure point.
Yes. Sealing a flashing leak early stops water from reaching sheathing, insulation, and framing. Left alone, a small leak can rot a 4-foot section of decking in one wet season. Repair costs a fraction of structural replacement. We also document the repair so you have proof for insurance or a future sale.
