Flashing chimneys

When flashing your chimney make sure you seal the corners as you run your step flashing. if you forget a corner your probably going to have a leak. Make your step flashing 8"x7" and break it to be 3" up the chimney and 4" out on the roof and you want a piece of flashing on every shingle to insure that you have the best protection. don't use one straight piece of flashing the water could run back under your roof and cause leaks
