Pre-Installation Checklist for Flashing Works

Check that penetrations are fully wrapped and that seams are positioned to reduce exposure to wind-driven rain. Verify fasteners are secured properly without overdriving, which can distort the metal. Inspect transitions at valleys, eaves, verges, and wall junctions for consistent geometry, and confirm sealant is applied where required, with no smearing or thin spots. After finishing, perform a visual sweep for misalignment, lifted edges, or gaps, then confirm the drainage paths are unobstructed.
