Take a look at the area to be illuminated
Measurement of the area that will be flashed is an important first step in the process of installing flashing on an existing roof. It is important to know the dimensions of the area to be flashed in order that you can buy the correct amount of flashing materials. Also taking measurements of the size of the area will provide you with an understanding of the roof structure and how the flashing will be placed.
Cut flashing to size
Start in cutting off the flashing to size. If you’re using a pan that’s already formed it’s just necessary to cut it long enough to extend 6 inches past the edge of the roof. For roll roofs you’ll need to cut it twice the length of the width of the roof. Then cut the flashing horizontally in half to create two pieces with the same length as the length of the roof.
Remove any old shingles and nails
To install flashing on an existing roof first you’ll need to take off any old shingles and nails. Once that’s done then you can put in your new flashing. Be sure to cover the new flashing by at least 2 inches and use corrosion-resistant nails and screws to secure it in place.

The first step is to remove any shingles or other materials that may be blocking the path. When the roof is clean it’s time be able to cut and measure the flashing to suit. Make sure you leave plenty of an overlap so that the flashing can be securely fixed on the roof. Once the flashing has been put in place, you can install the new shingles or other types of roofing material.
Nail flashing in place

Cover the seams using roofing cement
After you have cut the flashing strips to size, lay them out on the roof so that they are overlapping the joint in the roofing material by minimum 2 inches. Once the flashing is set, apply a continuous bead of roofing cement on the surface of the overlap. Utilize a putty blade for smoothing the cement, and then take off any excess.
Apply caulk all over the flashing
For installing roofing flashing you’ll need to apply caulk to the flashing. Begin by removing any old caulk and other debris from the area. Then, apply a large amount of caulk to the side of the flashing that is below it. Make sure you smooth it out until it’s even and level. Then, press the flashing into position and seal it with more caulk.
Install additional shingles if necessary.
If you are installing flashing on your old roof structure, it might require the installation of additional shingles to create an even surface for the flashing to stick to. Begin by removing any damaged or missing shingles. Then, apply the new shingles into the appropriate spot. Make sure you overlap the shingles in order that the flashing will be completely protected.
