How to install flashing on a roof edge.

Step flashing on roof peak. Lift the shingles and slide the top flange of the drip edge underneath. Drive the nail through the drip edge into the roof surface not through the fascia. After you ve correctly installed the valley flashing you can install the drip edge which is corner shaped and will be attached with nails along the edge of the roof.

Roof shingle over step flashing. Measure the length of the eave you need to cover with drip edge using a tape measure. The remaining siding on the sidewall will overlap the step flashing and nail. The drip edge should be nailed beneath the builder s felt but over the fascia board.

Select enough lengths of. If you do not wish to form your own corner flashing you can buy pre bent pieces and cut them to size or use a piece of corrugated aluminum which is easier to bend. Bend the corner flashing tightly around the corner. Install the step flashing when the siding is installed it should be tucked behind this piece and then consecutive courses lapped over it.

Start the installation at the lower edge of the roof and work your way up toward the peak.
