Skylight Leak Repair in SeaTac, Burien, WA
Skylight leaks are rarely the skylight's fault — they're almost always a flashing or curb problem. Roof Leak Repair Specialists is the local licensed expert for skylight leak repair in SeaTac, Burien, WA. Commercial flat roofs around the airport face constant HVAC traffic and puncture risks.
Skylight leak repair starts with determining whether water is entering around the unit or condensing inside it. We inspect the flashing kit, curb, and seals, then re-flash or reseal as needed — replacing the skylight itself only when the unit has genuinely failed. Residential streets under the flight path have 1950s–70s homes with aging roof systems.
Why Skylights Leak in SeaTac Homes
The skylight is a hole in your roof by design, and every edge of that hole is a flashing detail. In SeaTac we find aged step-flashing kits, cracked curb seals, and skylights installed without proper head flashing. SeaTac is the adjacent airport city of hotels, commercial buildings, and mid-century residential streets.
Re-roofs are a repeat offender: new shingles get woven around the old flashing kit, which then fails within a couple of years. We re-flash with a new kit matched to the unit.
- Cracked seals at the curb
- Low curbs buried by re-roof layers
- Missing head flashing above the unit
- Condensation mistaken for leaks
Repair vs. Replace: Your Skylight in Burien
A sound skylight with failed flashing gets a re-flash — typically a few hundred dollars and a permanent fix. A fogged, cracked, or 25-year-old unit with obsolete flashing gets our recommendation for full replacement.
Replacement also lets you upgrade: modern units with better glazing cut heat gain and UV damage to interiors. Residential streets under the flight path have 1950s–70s homes with aging roof systems. Either way, the quote is upfront and the work is water-tested.
- Replace when glass or frame has failed
- Upgrade options for energy efficiency
- Upfront pricing for both paths
- Re-flash when the unit is sound
What Skylight Repair Costs in SeaTac
Re-flashing a standard curb-mount skylight is one of the more affordable leak repairs; full unit replacement with a quality modern skylight costs more but adds decades of service and energy performance.
Multiple skylights with the same aged flashing kit can often be done together at a better per-unit price. Commercial flat roofs around the airport face constant HVAC traffic and puncture risks. Call (888) 974-0663 for a free estimate.

Skylight Leak Repair in SeaTac FAQs
How long does a skylight re-flash take?
Most single-skylight re-flashes are completed in half a day, including water testing. Full unit replacements typically take a full day.
Can you upgrade my old skylight to a modern one?
Yes. Replacement is a good time to upgrade to low-E glazing that cuts heat and UV. We carry and install current major-brand units.
Is my skylight leaking, or is it condensation?
That's the first thing we determine. True leaks worsen with rain and show staining around the curb; condensation appears in cold weather regardless of rain. Our diagnosis tells you which before any work is quoted.
