Expert Verdict — Reviewed by the SuperArbor Pro Desk
Install transition flashing so the lip laps over the field and the up-leg is protected by the wall covering, keeping water out of the joint. Use compatible fasteners and sealant per the shingle manufacturer's detail to avoid galvanic issues with galvanized steel. Order mill finish where the metal will be concealed or painted, black finishes where exposed.
Cut metal flashing edges are sharp; wear cut-resistant gloves and eye protection when handling or trimming flashing.
Order the TopShield mill-finish 4 in. x 4 in. 30 GA galvanized angle flashing with lip for clean transition detailing.
