Flashing Problems Around Your Chimney

Having a working fireplace in your home can create an ambiance and provide you with an additional source of heat. In order to allow for the safe exit of smoke, a hole must be cut in your roof to accommodate the chimney attached to your fireplace.

This hole is sealed with a metal product known as flashing to help create a waterproof seal that prevents moisture from seeping into your roof through the chimney hole. Here are three signs that indicate flashing problems around your chimney that you need to be watching for in the future.

1. Improper Contact

The first thing you need to do when trying to determine if the flashing around your home's chimney is in good repair is conduct a visual inspection of the areas where the flashing meets the chimney.

The metal should be in continuous contact with the chimney to eliminate any small openings where water can seep underneath the flashing and into your home's roof decking. If you see any bubbling or bends that break the line of continuous contact, you should replace the damaged flashing with new metal flashing to eliminate moisture-related roof damage in the future.

2. Rust

Since flashing is made from metal, there is always the possibility that the flashing surrounding your home's chimney will begin to oxidize. Contact with moisture and the elements can lead to the formation of rust on the surface of the flashing.

As this rust spreads, it compromises the structural integrity of the flashing. Eventually, the rust will render the flashing unable to perform properly. A quick visual inspection for signs of discoloration on the surface of your chimney flashing allows you to replace flashing that has started to rust before it becomes a serious problem.

3. Improper Installation

Taking the time to learn how flashing should be installed will allow you to determine if the flashing surrounding your chimney shows signs of improper installation. The metal base of the flashing that comes into contact with your home's roof should be sealed with shingles.

If you don't see any shingles covering the area where the flashing meets your roof, this improper installation could be allowing water to seep into the seam between the flashing and the shingles. Having a contractor correct the installation issue will ensure that flashing problems don't cause your home's roof to leak in the future.

By learning to identify some potential problems with the flashing surrounding your home's chimney, you will be able to ensure that damaged flashing doesn't cause your roof to leak. To learn more, contact a company like All American Roofing Incorporated
