Chimney Waterproofing and Flashing Repair


Most homeowners don’t think about their chimney on a daily basis, especially not their chimney roof flashing. It is just another structure, sitting outside, strong and steady. It weathers the blistering heat of St. Louis summers and the blustery cold. It stands exposed in rain, and snow and hail; all of which can have deteriorating effects on the structure.

A chimney can be made up of a variety of materials including stone, mortar, concrete, brick, flue tile, steel, cast iron and sheet metal. Water penetration is the single most damaging factor to your chimney, which makes chimney waterproofing crucial to the longevity of your home!

Some of the damage that water can cause includes:

In order to prevent these types of damages it is important to ensure your chimney roof flashing is in proper working order with yearly inspections. It is also a good idea to have these spots inspected after a major wind or hail storm, which can cause additional damage outside of regular wear and tear. An inspection will ensure that all of the joints, caps and flashings are properly waterproofed in addition to an inspection of the chimney structure itself.
