A Quick Guide on Protecting Your Chimney from Water Damage

According to theChimney Safety Institute of America(CSIA), water is the worst enemy of a masonry chimney because of how much damage it can cause. Preventing chimney leaks is one of the most important chimney maintenance tasks for homeowners to do, and All American Chimney Service is here to help the residents in the Louisville area protect their chimneys from water damage. We want to share this quick guide on how you can best keep water from damaging your chimney this year.

Chimney Cap

Called the most inexpensive way of preventing water penetration of your chimney by the CSIA, a chimney cap sits on the top of your chimney where it keeps water from rain and melted snow from getting inside. A good quality chimney cap has other important functions, including keeping birds, squirrels, raccoons, and other wild animals from moving into your chimney, stopping hot sparks and embers from jumping out of the top of the chimney, and directing wind flow to improve your chimney’s draft. All American Chimney Service can help you find the perfect cap for your chimney and professionally install it to best protect your chimney.

A Quick Guide On Protecting Your Chimney From Water Damage Louisville Ky All American Chimney


To protect the most vulnerable area for chimney water leaks, which is where your chimney meets the roof, flashing provides a watertight seal to keep leaks from occurring. Consisting of layers of metal sheets, flashing wraps around your chimney and is also attached to shingles on the roof. Over time, flashing can get damaged by weather elements, and damaged flashing can allow water to directly enter your chimney. All American Chimney Service can repair damaged flashing to restore its seal, and we can also customize a new flashing system if you do not already have one installed on your chimney.


Masonry materials are naturally porous, which means the bricks and mortar of your chimney easily absorb water. During the winter, the water can freeze and thaw inside your bricks and mortar repeatedly, and this leads to the masonry materials cracking and breaking apart. This type of damage can worsen if left unrepaired, and you could end up with some very expensive repairs that are necessary to be able to use your fireplace. The best way to reduce this kind of damage is to have your chimney professionally waterproofed. All American Chimney Service provide this service, and you can trust us to only use a waterproofing formula that is 100% vapor permeable. This means while water cannot penetrate into the bricks and mortar, any vapors can easily escape. If the vapors are trapped, it results in further deterioration.
