Service overview
What Skylight Leak Repair Campbell CA Really Involves
Skylight leak repair Campbell CA is the process of locating and sealing the exact point where water enters around a roof window, then restoring the surrounding roof assembly so it sheds water the way it was designed to. Most skylight leaks are not the glass itself. They come from failed flashing, dried-out sealant, cracked curb joints, or underlayment that has worn through after years of UV exposure. We open the area, inspect the curb and deck, and rebuild the waterproofing layers from the deck up.
Campbell homes take a beating from hot, dry summers followed by wet winters. That swing cracks old sealant and shrinks butyl tape around skylight curbs. Add a clogged gutter or a low-slope section that holds ponding water, and you get a slow leak that stains drywall for months before you notice it. If you have been searching for skylight leak repair near me Campbell, the fix is usually a flashing and seal rebuild, not a full skylight replacement.

Practical benefits
Why Campbell Homeowners Fix Skylight Leaks Early
A small skylight leak becomes a big repair fast. Here is what you get when you call us before the damage spreads.
Stop Water Damage Cold
A single skylight leak can soak insulation, rot the roof deck, and stain ceilings within one rainy season. We seal the entry point and dry out the area so the damage stops where it started. Most repairs take two to four hours, and you get a dry ceiling instead of a growing brown ring.
Protect Your Insulation
Wet attic insulation loses its R-value and stays damp for weeks. We check the surrounding batt or blown-in insulation with a moisture meter, replace what is saturated, and confirm the deck is dry before we close up. That keeps your energy bills from creeping up after the repair.
Keep Your Skylight Working
You do not need a new skylight to stop a leak. In most cases we reseal the curb, replace the flashing, and re-set the unit so it keeps delivering daylight for years. Fixing the leak protects the glass, the frame, and the interior trim you already paid for.
Avoid Mold and Mildew
Damp drywall and framing create the conditions for mold within 48 to 72 hours. We dry the cavity, treat any affected wood, and seal the leak so moisture stops feeding the problem. That is the difference between a repair and a remediation bill.
How service works
Our Skylight Leak Repair Process
We follow the same five steps on every skylight leak fix Campbell job, from the first call to the final water test.
Phone Intake
You call or book online, and we ask where the stain is, when it appears, and whether the skylight is on a pitched or flat section. That tells us whether to bring a hose test kit or plan for a drone inspection. We schedule a same-week visit, and most Campbell calls get a technician out within 24 to 48 hours.
Tools and methods
Tools and Methods We Use on Skylight Leaks
Moisture Meter
Reads moisture levels in drywall, insulation, and roof decking so we know how far water has traveled from the skylight. It tells us whether the damage is surface-level or deeper in the assembly.
Infrared Camera
Shows temperature differences that reveal hidden moisture behind walls and ceilings. We use it to trace the leak path when the stain is not directly under the skylight.
Hose Test Kit
Lets us apply controlled water to the skylight and surrounding roof while watching from inside. This confirms the exact entry point before we start the repair.
Pry Bar and Caulking Gun
Used to lift flashing and shingles without breaking them, and to apply sealant precisely along the curb. Clean edges are what make a seal last.
Drones for Roof Inspection
We use drones to inspect steep or multi-story roofs safely before sending a technician up. That gives us a clear look at the skylight and flashing from every angle.
Roofing Nailer
Re-secures shingles and underlayment around the skylight after the repair. Proper nailing keeps the surrounding roof tight so water cannot get back under the flashing.
NRCA Flashing Standards
We follow National Roofing Contractors Association flashing details on every skylight curb. That means proper layering of underlayment, step flashing, and counter-flashing so water sheds the way it is supposed to.
GAF and Owens Corning Systems
When we replace underlayment or shingles around a skylight, we use GAF or Owens Corning materials matched to your roof. That keeps the repair compatible with the rest of the assembly and protects any existing warranty.
Controlled Hose Testing
We do not guess. After the repair cures, we run water over the skylight for 15 to 20 minutes and watch from inside. If moisture shows up, we keep working until the test is dry.
Moisture Mapping
Using the moisture meter and infrared camera together, we map how far water has spread from the skylight. That tells us what to replace and what can stay, so you do not pay for work you do not need.

Where this service fits
When to Call for Skylight Leak Repair
You notice a brown water ring on the ceiling under your skylight after the first big winter storm.
We inspect the skylight curb and flashing, run a hose test to confirm the entry point, and repair the failed seal or flashing. Most jobs are done in one visit. The ring stops growing, the leak is sealed, and you have photos and a warranty to show for it.
Your skylight drips only when the wind blows rain sideways against that side of the roof.
Wind-driven leaks often come from a gap in the counter-flashing or a lifted shingle near the curb. We check both, reseal the gap, and re-secure the surrounding roofing. The skylight stays dry even in the wind-driven storms that used to soak your ceiling.
You are selling your Campbell home and the inspection report flags a skylight leak.
We diagnose the leak, repair it, and provide documentation with photos and a warranty. That gives the buyer confidence and keeps the sale on track. The repair is documented, the leak is fixed, and the inspection item is cleared.
Your flat-roof commercial building has a skylight leaking into a tenant space.
We work around business hours, repair the membrane and curb flashing, and clear the drain path so ponding stops. We keep the disruption to a minimum. The tenant space stays dry and the roof drains properly after the next rain.

How Skylight Leak Repair Runs in Campbell
Campbell sits in Santa Clara County with hot, dry summers and wet winters, and that swing is hard on skylight seals. Summer UV bakes the sealant around the curb until it cracks, then the first heavy rain finds the gap. Many Campbell homes were built in the 1950s through 1970s with skylights added later, so the flashing details vary from house to house. We see a lot of older butyl tape that has dried out and step flashing that was never layered correctly. If you need a skylight leak fix in Downtown Campbell, we check the curb, the flashing, and the surrounding underlayment before we quote the repair. We also look at gutters and valleys, because a clogged gutter can push water sideways under a skylight and make it look like the skylight itself failed. For homeowners near San Tomas, we can often schedule skylight leak repair open now Campbell visits when a storm is coming and you need the roof sealed fast.
Downtown Campbell
Older homes with mature trees mean more debris in gutters, which pushes water toward skylights. We check the gutter path on every Downtown Campbell repair.
Willow Glen
Many homes here have pitched shingle roofs with skylights added during remodels. We see flashing that was installed without proper step layering, which leaks within a few seasons.
Pruneyard
Commercial and mixed-use buildings with flat roofs and skylights. Ponding water near curbs is the most common leak cause we find here.
San Tomas
A mix of older and newer roofs. We often find dried butyl tape and cracked sealant around skylight curbs on homes near San Tomas.
Campbell Village
Residential roofs with skylights over kitchens and hallways. Ceiling stains here usually trace back to curb flashing that has pulled loose.
Hot summer UV exposure cracking sealant
Sealant around skylight curbs dries and cracks faster here than in cooler climates. We use UV-rated roof cement and butyl tape so the new seal lasts through multiple summers.
Winter rain finding failed flashing
Once the sealant cracks, the first heavy rain gets behind the flashing. We schedule extra availability in fall and winter so Campbell homeowners can get a repair before the ceiling stains.
Clogged gutters pushing water sideways
Debris-filled gutters overflow and send water under skylight flashing. We clear the gutter path as part of the repair so the leak does not come back from the same cause.
Low-slope sections with ponding water
Flat and low-slope roofs hold water against skylight curbs. We repair the membrane and improve drainage so water moves off the roof instead of sitting against the skylight.
Problems we solve
Skylight Leak Problems We Solve in Campbell
If you are dealing with any of these, we can help. We see the same skylight failures over and over in Campbell, and we know how to fix them.
Ceiling stain that grows after every storm
We trace the water to the skylight flashing or curb, repair the entry point, and check the cavity for moisture. Once the source is sealed, the stain stops growing and the drywall can be repaired. The stain means water is already in the drywall and insulation. Left alone, it spreads, softens the drywall, and can reach the framing within a few wet seasons.
Drip that only shows up in heavy rain
We use a hose test kit to recreate heavy rain on demand. That lets us find the exact gap, even when the leak will not show up on a dry day, and fix it before the next storm. Intermittent leaks are the hardest to diagnose and the easiest to ignore. They still rot the deck and insulation a little more each time it rains.
Skylight sealant cracked and peeling
We remove the old sealant, clean the curb, and re-seal with roof cement and butyl tape rated for UV exposure. We also check the flashing while we are up there so the new seal is not hiding a bigger problem. Campbell summers bake the sealant around skylight curbs until it cracks. Once it fails, water gets behind the flashing and the leak starts.
Water pooling around a flat-roof skylight
We repair the membrane around the curb, re-flash the skylight, and improve the drain path so water moves off the roof. That stops the ponding that caused the leak in the first place. Ponding water sits against the skylight curb and works its way under the membrane. Over time, it can rot the curb and the deck around the opening.
A practical standard for every visit.

Where we work
One local team. A lot of ground covered.
Most skylight leak repairs in Campbell run $350 to $900 in 2026, depending on whether we are resealing a curb or rebuilding flashing and underlayment. A simple seal replacement sits at the low end. If the deck is rotted or the skylight needs to be re-set, expect the higher end. We give you the price before we start, and the water test is included.
Yes, in most cases we can. The skylight glass and frame usually outlast the flashing and sealant around them. We rebuild the curb flashing, replace the butyl tape and underlayment, and re-seal the unit. You keep the skylight you have and stop the leak. Full replacement is only needed when the frame itself is cracked or the glass seal has failed.
The three most common causes we see in Campbell are failed flashing at the curb, dried-out sealant from summer UV exposure, and clogged gutters that push water sideways under the skylight. Ponding water on low-slope sections is another culprit. A moisture meter and hose test tell us which one you have, usually within 45 minutes of arriving.
A standard skylight leak fix in Campbell takes two to four hours on site. That includes diagnosis, the repair itself, and a 15 to 20 minute water test. If we find rotted decking or have to order a matching shingle, we may need to schedule a return visit. We tell you the timeline before we start.
