How do I Install a Edge Flashing on a Patio Roof?

Your roof is one of the most important parts of your home. Whether it is your patio roof or your house's roof, unprotected edges of a roof can lead to rot and decay, undermining the efficiency and integrity of the structure. Therefore, it is important to make sure that all edges of your roof are protected. The simplest way to do this is to cover them with metal edge flashing; a small investment of time and money that can save your roof and your pocketbook thousands of dollars in the long run.

Protect your roof by installing metal flashing.
  1. Prepare the patio roof by clearing away all dirt and debris with a hand brush. Measure the edges of the patio roof to determine how much edge flashing you need.

  2. Cut the edge flashing using metal snips. If the measurements of the patio roof are longer than the pieces of the edge flashing, lay whole pieces of edge flashing end to end, and cut a smaller piece to fit the remaining space.

  3. Lay the edge flashing by beginning at one corner of the roof. Place the pieces of edge flashing on the front lower edge of the roof. Hammer in 1 1/4-inch electrified iron nails, spacing the nails at 2-inch increments.

  4. Create a butt joint on the corner of the roof by overlapping the two pieces of edge flashing. Push together the pieces of flashing, making sure the corner is tight and secure. Hammer a nail into the flashing to the butt to secure it.

  5. Continue to lay the edge flashing until all of the edges and corners of the lower edge of the roof are covered.
