WESTERN LOCK® STANDING SEAM METAL ROOFING

Transition Flashing - Low To High - Detail - Part #WS-437

Transition flashing is used when you have a roof that has two different pitches. The transition trim is located where the two different pitches meet so the metal roof does not leak. Transition flashing is also referred to as pitch break trim and comes high to low or low to high.
