If your home has asphalt shingles, you will most likely have roof flashing around any areas where the roofing material meets a vertical surface, such as at the top of a chimney. Over time, the flashing can become cracked or brittle and will need to be replaced. This is a relatively easy repair that can be done in a few steps.

There is no one-size-fits-all answer to this question, as the type of roof flashing and the size and shape of the roof will dictate the best way to replace it. However, in general, the process of replacing roof flashing involves removing the old flashing and measuring and cutting new pieces to fit in its place. Once the new flashing is in place, it should be sealed with caulk or waterproof tape to prevent leaks.

Should you replace flashing on existing roof?

If your flashing is in good condition, you may be able to salvage it. However, if there are any holes or rust, it is always best to replace it. Metal flashing should be replaced at the same time as your roof to ensure the integrity of your roof.

Next, cut a section of flashing that is roughly six inches larger than the damaged piece that was removed. Be sure to use a sharp knife or metal shears to avoid damaging the flashing. Once the new piece is cut, gently bend it into place and use a hammer to lightly tap it into place. Finally, use a caulk gun to apply a bead of silicone caulk around the perimeter of the new flashing to seal it in place.
