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.

How long should roof flashing last?
Flashing repairs are expensive, so we recommend replacing all flashings when getting a new roof. Life expectancy of roof flashing is 40 years when installed properly. Repairing flashing costs 4-5x more than it does to replace it during a new roof installation.
The cost of repairing or replacing flashing will depend on the material used, the size and location of the damage, and the type of structure. Generally, the cost of fixing flashing is anywhere between $15 to $25 per linear foot, which includes both the price of the new flashing itself and the caulking used to seal it in place (which is about $10 on its own or sometimes more). A total flashing replacement might cost anywhere between $300 to $600.

What is damaged flashing on roof
Flashing is one of the most important parts of your roof, as it protects the most vulnerable areas from water damage. Any damage to flashing, such as cracks or bent edges, can allow moisture to seep inside and cause problems, especially during heavy rains. If you notice any damage to your roof flashing, it’s important to have it repaired as soon as possible to avoid costly repairs down the road.
Most homeowners insurance policies will cover roof leaks that are caused by sudden, accidental events, such as storms or fallen trees.
