Water-managed envelope: continuous drainage plane behind cladding, kick-out flashing at all roof-wall intersections, pan flashing at all windows + doors
ENERGY STAR SFNH §Rater Field Checklist — Section 4 (Water Management)Description
ENERGY STAR water-management requirements: capillary break above foundation (sill seal or rigid foam); flashing at all wall penetrations (window pan + head + jamb; deck ledger flashing; exhaust duct sleeve); kick-out (diverter) flashing at every roof-meets-wall intersection that terminates above a wall (where water would otherwise pour over the cladding); ice + water shield at eaves in climates with freezing; properly-sized gutters discharging ≥ 5 ft from foundation OR to a drain.
Why this exists
ENERGY STAR's water-management checklist is the architect's envelope-detail playbook. The kick-out flashing is the most-missed item — a small piece of bent metal saves thousands of dollars in water damage. Architects should show the kick-out detail in the roof-wall intersection callout on every plan.
