Revitalizing Roof Flashing Revitalizing Roof Flashing

Roof flashing needs periodic maintenance in order to be effective in preventing water damage. Roof flashing is installed along chimneys, vents and roof pipes where these openings meet the roof line.

Resealing
At least once a year, the roof should be inspected. The best time of year for this project is at the end of summer, before the weather becomes cooler and winter rain and snow begins. Often, at the end of summer, roof flashing needs to be recaulked because the heat of the summer has resulted in the caulk material being damaged or peeling away.

Remove any damaged or peeling caulk and using a 100 percent water proof silicone caulk, apply a bead of caulk along roof shingles where they meet flashing materials. Also apply another layer of caulk where the flashing meets chimney masonry or other materials. This will completely seal the flashing and prevent water from entering between the flashing and the roof materials.

Roof Cleaning
Another way to revitalize your roof flashing is to make sure that there is no accumulated dirt and debris on the roof. Each season you should climb up on the roof and remove leaves, twigs, branches and anything else that has accumulated on the roof over the past several months. Very often, if these items are allowed to pile up, they will result in the roof flashing becoming ineffective because water is allowed to build up against the debris instead of being diverted by the flashing.
