Chimney Flashings

Also known as tuck point chimney flashing, chimney wall flashing, metal chimney flashing or roof flashing.

A chimney flashing is used to seal and protects joints in a building from water penetration. It is highly recommended to replaced the chimney flashing when ever you have a new roof installed. This insures that your chimney flashing will last the life of your roof.

The joints created by the intersection of the roof and roof mounted structures, such as parapets, hatches, skylights, chimneys, vent stacks, or towers, are among the most vulnerable areas of roofing systems. They constantly expand and contract in response to changes in humidity and temperature. The greater the number of such projections, the greater the potential for serious leaks. Flashing is used at these intersections to keep rainwater from leaking into the building. It makes joints at these junctions watertight, while at the same time allowing the natural expansion and contraction of materials to continue. It operates on the principle that, in order to penetrate a joint, water must work itself upward against the force of gravity, or in the case of wind-driven rain, would have to follow a tortuous path during which the force of the wind would be dissipated.
