In this article, we will present you a few examples of flashing in use.

Chimney flashing

Around a chimney, one must use continuous flashing across the bottom, as well as step flashing to cover the sides of the chimney walls. This will prevent water from pooling between the chimney bricks and the roof. Often, professional San Jose roofing contractors can also add cap flashing over the other flashings, for extra-protection.

Dormer flashing

Dormer windows must be protected with flashing squares, inserted between the rows of the roofing material, or flashing strips used under the roof and around the dormer.

Skylights flashing

Although in many cases skylights are designed with a built in flashing, you can add extra protection. There are three flashing shapes to be used in the case of skylights: continuous flashing (at the base of the window), step flashing (up the sides) and saddle flashing (on the top).

Vent pipe flashing

It has a conic shape, with a flange at the base to be worked into the shingles.
