Measure the area to be flashed

Measuring the area to be flashed is a crucial first step to install flashing onto an old roof. It is important to know the measurements of the space to be flashed, so that you are able to purchase the right quantity of flashing material. Additionally measuring the size of the area will give you more understanding of the roof structure and how the flashing will need to be installed.

Cut flashings to the size you need

Start in cutting off the flashing to size. If you’re using a pre-formed pan it’s just necessary to cut it long enough to extend 6 inches beyond the roof’s edge. In the case of roll roofing make the flashing cut twice the length of the length of your roof. Then, cut the flashing horizontally in half to create two pieces that are the same length as the length of the roof.

Remove any old shingles and nails

For installing flashing on an existing roof, first, you’ll have to remove the old shingles and nails. After that then you can put in the flashing. Make sure that you overlap the flashing with at least 2 inches, and use corrosion-resistant nails or screws to secure it into place.

Make sure that flashing is secured to the roof

If your house has an roofing system that is in place, you’ll need to be careful in putting up flashing. First, take off any shingles and other materials that might be in the way. When the roof is clean then you’ll have be able to cut and measure the flashing to fit. Be sure to leave enough for an overlap so that the flashing is secure attached to the roof. Once the flashing is installed, you are able to install the new shingles , or any other roofing materials.

Nail flashing in the right place

1. Make sure the surface is free of any debris.

2. Find the area that needs to be covered, then cut the flashing according to the area.

3. Apply a good amount of adhesive to the side of the flashing.

4. Press the flashing into place and hold it there for a couple of minutes to let the adhesive become firm.

5. Fix the flashing with roofing nails.

6. Apply a small amount of sealant around the perimeter of the flashing to seal it in position.

Cover the seams using roofing cement

After you have cut the strips of flashing to length, spread them on the roof, so that they are overlapping the joint in the roofing material by at least 2 inches. Once you have the flashing set, apply a continuous bead of roofing cement to the surface of the overlap. Use a putty knife to smooth out the cement and remove any excess.

Apply caulk all over the flashing

To install the flashing onto an already-existing roof you’ll have to put caulk on the flashing. Start by cleaning any old caulk and other debris off the surface. Then, apply a large amount of caulk to the underside of the flashing. Make sure to smooth it out so that it’s even and level. After that press the flashing into the desired position, and seal it using more caulk.

Install additional shingles if needed

If you are installing flashing on an existing roof, you might require additional shingles in order to create a solid surface for the flashing to stick to. Start by removing any damaged or loose shingles. Then, apply the new shingles into the appropriate spot. Be sure to cover the shingles so that the flashing is completely covered.

If you’re considering installing flashing on your current roof there are some things to be aware of. First, make sure you’ve got the proper equipment and materials. Then, take your time and make sure you don’t harm your roof. And third, if you’re not sure which direction to take you should employ a professional. With just a little planning and attention you can put flashing on your roof to ensure that your home is in good shape for decades to be.
