Chimney Flashing

Posted by Robert Evans on Oct 13, 2014 2:59:00 PM

Chimney flashing

Chimney Flashing is a vital part of your roof. Robert Evans Jr. Contracting Inc. gets more calls about leaks around chimneys than about any other problem. And more often than not, the culprit is the flashing, the metal that keeps the intersection between the chimney and roof watertight.

Proper flashing around chimney includeds 2 layers. The first is called step flashing: L-shaped aluminum are woven into the shingle courses and lapped up the side of the chimney. Next comes the counterflashing: A second layer of metal usaully consisting of either Lead or Copper. {Most commonly used is Lead} It is embedded in the chimney mortar joints and folded down to cover the top of the step flashing

The corners are especially vulnerable. We usaully cut and bend the lead around the corner. Even with a good quality installation, this leaves one small spot that should be sealed with a high-quality Caulking such as Geocel.

The type of metal used for flashing depends on where you live. Aluminum and galvanized steel are sometimes used. Copper is the longest lived, but because its so expensive, we see it only on higher end jobs. Another advantage to copper is that the corners can be soldered for a watertight connection.

When a chimney is located at the bottom of a roof slope, a cricket should always be installed, a small diversion roof that prevents water from pooling and ponding behind chimney and eventually leading to seeping through roof into your house.

Because chimneys are such a potential trouble spot, inspect them once a year or two for loose or missing flashing and cracks in the masonry, or call on Robert Evans Jr. Contracting at 508-877-3500 and have one of our professionals do the inspection for you.  We also recommend that our customers waterproof their brick chimneys every few years with a brick sealer that can be applied with a garden sprayer. This is a great way to keep water from seeping into the brick.
