Easy-to-install and Durable Step Flashing

Protect your home from unwanted moisture and leaks by installing step flashing. This durable material is bent at 90 degrees and installed where the roof lines meet at an angle. Layering step flashing while installing your roof and other exterior finishes creates a necessary barrier to channel water runoff from shingles into gutters — preventing water from getting trapped and weakening the roof support.


Step flashing is available in a range of weather-resistant materials like plastic, aluminum and galvanized steel. Available in brown, white, black, blue, green and silver, your choice of step flashing will seamlessly blend in with your roof and siding. Explore sidewall flashing to install where the side of the roof lines up against an adjacent wall between levels of a house.


Step flashing is also necessary for installing skylights, chimneys, decks, doors, vents, windows and other structural features on your house. Feel secure about protecting your home from any interior or exterior damage by installing it yourself or hiring a professional.
