Help When Flashing Fails

Help When Flashing Fails

Have you noticed water stains on the ceiling or walls around your chimney? If your roof isn’t damaged, chances are your chimney flashing may be to blame.
Flashing is the sheet metal installed around the part of the chimney that comes through the roof. This helps keep it watertight. Failure of this metal component is a common cause of leaks. If it is damaged or corroded due to the elements or if it is improperly installed, moisture can find its way into your home. If not taken care of promptly it can result in damage to your ceiling, walls, and may even make it necessary for you to replace your whole chimney!

If you have access to an extension ladder, take a look at the flashing around your chimney. There should be flashing installed where the chimney meets the roof. Step flashing is the metal that is bent up against the base of the chimney. Counter flashing is the metal that’s bent down over the step flashing. If there are parts that are corroded, missing or bent out of shape then a chimney expert should be called in to repair it. If the flashing is in good condition, caulking may take care of the problem. You can use a tube of polyurethane flashing sealant to fill gaps.
Once sealant is applied and set, spraying the area with a hose can determine if the gaps have been properly sealed. If it continues to leak, more applications of sealant will be necessary. If you are unable to seal the gaps, calling in an expert like North American Chimney & Gutter, Corp. may be necessary.
