Skylight Leak Repair by ARCM Roofing
Expert skylight leak repair that seals your roof, protects your interior, and restores natural light without the water damage.
5 Highlights on Skylight Leak Repair
Natural Light, Minus the Water
We stop water intrusion around skylight curbs, flashing, and glazing on asphalt shingle, metal, tile, and flat roof systems — residential and commercial.
Complete Flashing Repair and Replacement
We flash skylight curbs with step flashing, saddle flashing, and continuous head flashing to redirect water away from the opening.
Glazing and Seal Restoration
Our crews reseal failed gaskets, cracked acrylic domes, and fogged insulated glass units before moisture reaches your drywall.
Curb and Deck Waterproofing
We waterproof the skylight curb with ice and water shield membrane, then integrate it with your existing underlayment.
Leak Diagnostics With Moisture Detection
Technicians trace water paths using moisture meters and infrared inspection, so we repair the actual source instead of the visible stain.
Full Replacement When Repair Falls Short
We install new deck-mounted and curb-mounted units from trusted manufacturers when the existing frame has failed.
If water returns through our repair, we come back and fix it at no charge.
Why Choose Us
We Quote the Repair, Not the Panic
Many customers call us after another contractor recommended a full roof replacement for what turned out to be a $400 flashing repair. We tell you what the skylight actually needs, back it with photos, and let you decide.
Our licensed, insured, factory-trained crews hold manufacturer certifications for major skylight brands, which means your repair follows installation specs that keep warranties intact. And we don't guess: we inspect the flashing kit, probe the curb, test the weep holes, and check the interior condensation channel before we recommend anything.
Every repair carries our written 1-year repair warranty, with a detailed estimate before work begins, photo documentation during, and a final walkthrough when we finish. Same-week scheduling rounds it out.
Moisture meters and infrared inspection find the actual source — we repair the entry point, not just the visible stain.
Warning Signs
Signs You Need Skylight Leak Repair
Warning signs usually appear before major damage sets in. Catch them early and repair stays affordable; ignore them and you're facing rotted sheathing, mold remediation, and interior restoration.
Water Stains Around the Skylight Shaft
Brown or yellow rings on the light well or ceiling below the unit indicate active water intrusion. Stains that grow after rainfall point to failed step flashing or a compromised curb seal rather than condensation.
Dripping During or After Rainstorms
Active drips from the skylight frame corners signal a breach in the head flashing or a deteriorated gasket. Water often travels along rafters before it drops, so the leak source may sit several feet upslope from the drip point.
Fogging Between Glass Panes
Condensation trapped inside an insulated glass unit means the hermetic seal has failed. A fogged IGU won't leak immediately, but the failed seal invites water infiltration and reduces thermal performance until we reseal or replace the glazing.
Cracked or Discolored Acrylic Domes
Older dome skylights turn yellow, become brittle, and craze under UV exposure. Hairline cracks in the dome let wind-driven rain enter the curb cavity, where it soaks the insulation and rots the framing.
Deteriorated Roofing Around the Skylight
Curling shingles, rusted flashing, exposed nail heads, or cracked sealant beads at the perimeter all channel water beneath the roof deck. Granule loss concentrated around the curb often reveals where water has pooled against poorly integrated flashing.
First stain, drip, or fog? Call now — small leaks rot decking within months.
How We Work
Our Skylight Leak Repair Process
01
Inspection and Diagnosis
A technician examines the skylight inside and out — glazing, gaskets, weep system, flashing kit, curb, and surrounding roofing. Moisture meters and water testing confirm the entry point.
02
Written Estimate
You receive a detailed scope of work with photos of the damage, the recommended repair, and a firm price. No surprises, no pressure.
03
Repair Execution
Crews remove the roofing around the skylight, strip the failed flashing, and inspect the deck for rot. We replace damaged sheathing, apply ice and water shield around the full perimeter, then install new flashing in the correct shingle-lapped sequence.
04
Sealing and Glazing Work
We reseal glazing gaskets, replace failed IGUs or domes, and clear the condensation weep channels so the unit sheds water the way the manufacturer designed it.
05
Water Test and Cleanup
We flood test the repair with a hose, verify the interior stays dry, photograph the finished work, and haul away all debris. You get the photos, the warranty paperwork, and a dry skylight.
Most residential skylight leak repairs finish in a single day.

FAQs
FAQs About Skylight Leak Repair
›What is skylight leak repair?
Skylight leak repair is the process of diagnosing and sealing water intrusion points around a skylight, including the flashing, curb, glazing, and gaskets. Repairs range from resealing a gasket to replacing the full flashing kit.
›When should I schedule skylight leak repair?
Call at the first water stain, drip, or fog between panes. Small leaks rot roof decking within months, and early repairs cost a fraction of structural restoration.
›Why does my skylight leak even though the glass isn't broken?
Most skylight leaks start at the flashing, not the glass. Failed step flashing, cracked sealant, or a deteriorated curb lets water in around the unit while the glazing stays intact.
›How does skylight leak repair work?
We inspect and water test the unit, strip the surrounding roofing, replace the flashing and waterproofing membrane, reseal the glazing, then flood test the repair before we leave.
›Can you repair a skylight without replacing it?
Yes, in most cases. Flashing repairs, gasket resealing, and dome replacement solve the majority of leaks. We recommend full replacement only when the frame or curb has failed beyond repair.
›Does homeowners insurance cover skylight leak repair?
Policies often cover sudden damage from storms or falling debris but exclude wear and age related seal failure. We document every repair with photos to support your claim.
›How much does skylight leak repair cost?
Simple reseals start in the low hundreds. Flashing replacement runs higher, and full unit replacement varies by size and brand. ARCM Roofing provides free written estimates before any work begins.
