Skylight replacement
Skylight Replacement in Greater Seattle
Replacing old or leaking skylights and the flashing that ties them into your roof, with an inspection first to find out whether replacement or a flashing repair is the right fix.


How Skylight Replacement works
A skylight is a hole in the roof that has to be sealed well. When a skylight leaks, fogs between panes, or has cracked glass or a failing frame, replacing it together with new flashing is often the lasting fix.
Many leaks around skylights come from the flashing or the roof around it rather than the unit itself. We check both before recommending a replacement, and we explain if a flashing repair is enough.
Skylight replacement, explained
Replacement versus flashing repair
If the skylight unit is sound and the leak comes from failed flashing, a flashing repair may be enough. If the glass, seals or frame have failed, or the skylight is old, replacement is usually more practical.
How a skylight ties into the roof
The skylight is set on the roof opening and sealed with flashing and underlayment that work with the surrounding roofing to shed water around it. The specific flashing depends on the skylight and the roofing material.
What affects skylight replacement cost
The skylight size and type, whether it is fixed or opening, the roofing material, roof pitch and access, any framing changes, and interior finish work.
Replacing skylights during a reroof
During a roof replacement the roofing around the skylight is removed anyway, so it is often a good time to replace an aging skylight.
