Reseal the Flashing
If you determine the water is indeed coming from the flashing, the next step is to go on the roof with a caulk gun and the appropriate sealant. Hill recommends sealant designed specifically for roof flashing, such as Loctite Roof & Flashing Sealant. Butyl and silicone sealants are not recommended for this project.
You May Need to Reinstall the Flashing
Quality skylights come with flashing, which Hill says is leakproof when installed correctly. Without knowing it, however, a DIY or inexperienced pro installer could damage the flashing by nailing it to the roof, which Hill says you should never do.
