When installing a skylight on a sloped roof, the head and side flashing should be integrated with the roofing so that:
a.Water sheds over the flashing and down the roof, with step/counter flashing lapped shingle-style
b.The flashing sits on top of the finished roofing at the head
c.Only sealant seals the skylight to the deck
d.The curb is set directly on the roofing felt with no flashing
Giải thích
Skylight flashing must be woven into the roofing shingle-style, with head flashing under the upper courses and step/side flashing lapped so water always runs over the flashing and down-slope. Flashing over the head roofing, sealant only, or a bare curb all invite leaks.
