Can I install roof flashing around a chimney?

You can install roof flashing around a chimney. Newly built houses have foundations of the house and the chimney set in different directions, thus creating a gap between the chimney and the roof. It is through this gap that water leaks sometimes occur. There are 2 types of flashing that are usually installed around the chimney’s slope: step flashing, which is the first line of defense from rain and snow, and the cap flashing, which is built on top of the step flashing to protect the step flashing. It works as the second layer of protection.
