THE following photograph shows a skylight properly flashed ready to receive the felt strip over the joint. The roof shown is felted and ready for the final coat of pitch and slag, after the flashing flange has been covered with the pitch and felt strip.

While the foregoing photographs show copper flashings in one piece of metal, in the best practice against brick walls where the roof is laid over wooden beams the flashing metal is used in two strips, base and cap. The cap should be built in the wall not less than 2 inches with a downward flange of about four inches as shown in the following illustration.

   The base piece which turns out four inches on the flat stands up against the wall 6 to 10 inches and under the cap about 2 or 3 inches, thus fully providing for the shrinkage of the roof beams and boards.
