Proper installation of this flashing is absolutely vital to any home with a chimney. This can be easily overlooked if you rarely use your fireplace. If you are experiencing water leakage in your home and have already replaced the roof and/or siding, chimney flashing is the likely culprit.
A chimney, though usually made of concrete, is one of the most delicate parts of your home. A seal around the base called “flashing” protects your home from any water coming between your roof and chimney.
