Since your chimney extends from your roof, it is exposed to all of the elements of weather, including rain and snow. While masonry chimneys are built to last the lifetime of a house, this constant exposure to water from rain and melted snow can cause damage and deterioration to a chimney, especially if it is neglected. The Chimney Safety Institute of America (CSIA) claims that water is the biggest enemy of a masonry chimney and recommends regular maintenance to prevent expensive repairs due to water penetration damage and deterioration. Hudson Chimney would like to tell you more about how water damages your chimney and how we can help prevent this damage and deterioration.
How can water damage my chimney?
According to the CSIA, all of the masonry materials that are used to build a chimney can suffer from accelerated damage after being exposed to water for a long period of time. Water causes the bricks and mortar to erode, and during the winter when the temperature drops below freezing, any water that has been absorbed into the bricks and mortar will freeze and expand. When the weather warms up, this water will thaw and cause the masonry materials to crack and break apart. This type of damage is also known as spalling, and if left unrepaired, it can lead to bricks and pieces of mortar falling from the chimney as well as the collapse of the entire structure. If water leaks into a chimney, it can also cause rusting damage to the liner, damper, and other metal components, and it can even damage the interior of your home by staining ceilings and walls.
How can Hudson Chimney protect my chimney from water damage?
Our CSIA-certified chimney technicians have several ways to prevent water penetration of your chimney: chimney caps, flashing, and waterproofing.
Called the least expensive way to prevent water penetration of a chimney, a chimney cap keeps water from even entering into your chimney. We have several different types of caps, and our chimney experts can help you find the perfect cap for your chimney and install the cap to completely cover the opening. Chimney caps have other benefits as well, including keeping birds and animals out of the chimney and preventing hot embers and sparks from jumping out of the chimney to ignite an accidental fire. We also have chimney caps that can help improve the draft in your chimney if you have problems with backdrafting.
Consisting of pieces of metal, flashing wraps around your chimney where it meets the roof to keep water from getting in at that point. In our years of working on chimneys, we have seen inadequate flashing systems that are coming apart and actually let water enter into the chimney. We construct customized flashing systems to completely protect your chimney from water penetration. We also work with state-licensed roofers to ensure the flashing fits correctly along the roof.
Using a 100% vapor permeable formula, our chimney technicians can waterproof your chimney by applying a coat of this formula to your entire chimney. We use ChimneySaver products that are designed especially for chimneys. This formula provides a barrier on your masonry chimney that keeps water from leaking into the bricks and mortar but allows fumes and vapors to easily escape so that they do not become trapped to cause further damage.
