Can the Galvanized Steel Roll Valley Flashing be cut with tin snips?

Cutting metal roofing panels needs to be done with utmost care.

Cutting metal roofing panels needs to be done with utmost care. Due to the galvanized zinc coating on the panels scratched or cut edges are prone to rusting, so cutting these panels should be done with minimal risk of damaging them. Professional contractors use a tool known as a nibbler but if you only have a few cuts to make this can be accomplished with tin snips or a Metal Carbide tip blade. Panels should be cut from the underneath side, being careful to remove any of the burrs. Always wear gloves and protective eye wear.
