Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pre-bent aluminum step flashing speeds up roof-to-wall work since each piece is ready to weave into the shingle courses. Keep the vertical leg against the wall and the horizontal leg under the overlapping shingle, with each piece lapped by the next course of shingles. On masonry, seal the vertical leg with an approved sealant rather than relying on fasteners alone.
Aluminum flashing edges can be sharp; wear gloves and eye protection while handling and cutting.
