Flashing around the chimney may be the most difficult and important parts of the whole shingling process. Bend several 7-inch pieces of flashing, one each for each row of shingles that will butt up against the chimney. Have these ready; as you shingle up from the bottom interlace them between each layer from bottom to top. Prepare an apron as shown in the illustration made of sheet metal to surround the top side of the chimney where it meets the roof. This is placed just before installing the row of shingles that passes over the upper side.



You're not done with the chimney yet. Make another apron similar to the one at the top. Placing it over the shingles that were laid in front of the chimney, butt it up against the chimney, putting the corners under the side flashing. Now on the sides prepare a counterflashing which is a long sheet cut in a stair step pattern. Make sure the counterflashing is placed inside the top apron but wrapped around the outside of the corner of the lower apron. Cut and arrange your flashing so that water flowing off the chimney will not be channeled beneath the shingles. Tar the sides of the chimney where they meet the flashing.
