New Flashing

Chimney flashing is a sheet of metal installed around the area where the chimney meets the roof. Flashing ensures that the connection between the chimney and roof is watertight. Though these metals last for some time, they do have an expiration date that varies by wear.

• Step Flashing. Step flashing is the flashing that is incorporated into the shingle
• Counter Flashing
• Smaller crickets may be installed that are covered with metal flashing materials
• Rubber

There are several parts that make up the chimney flashing. The first part is the base, which is right under your roof’s shingles and bends upward against your chimney’s exterior.

The counter flashing is on top of the base.  The purpose of this is to seal off the top part of the base flashing.

For chimneys wider than 30 inches, most people use a saddle flashing. The reason for this is because it creates a peak that will allow water and snow to run off and away from the chimney. It also prevents damage to the chimney and your roof overall.

There are many materials that can use for flashing; the important thing is that they do not degrade from coming into contact with incompatible materials and that they are impermeable to water. The most common flashing materials are metal, plastic, or rubber.

Your home will stay protected from moisture and water damage, making your loved ones safe as well.

Other materials that can use as metal flashings include aluminum which is also durable and relatively inexpensive. However, aluminum will corrode if left in contact with pressure-treated wood, and also wet mortar and plaster.

Today the flashing is on top of the siding. That is fine but it must still look like the flashing is behind the siding. This flashing should not be seen for it disrupts the architectural balance of the house.
