Why Your Chimney Needs a Cap

The seasons finally transitioned, and autumn is in full force. Chilly winds have started stripping trees of their colorful leaves, and everyone is digging up their cold weather clothes. In New York, the cold weather sets in fast, so many people have already started to think about heating their homes. For the homeowners who use fireplaces or stoves to heat the house, a little extra work is in order to keep the heating appliance functioning safely. Every year, the fireplace and chimney need to be professionally swept and inspected. This should cover most of the bases to keep your home and family safe. One little piece that sometimes goes forgotten though – the chimney cap and it deserves a bit more attention.

The chimney cap sits on the very top of the chimney and serves as a cover for the inside of the chimney. They are relatively inexpensive, usually made of copper or steel, and are too often forgotten about, especially considering how important they are. Chimney caps have the simple yet vital purpose of preventing objects that do not belong in the chimney from entering in the first place.

Common but troublesome chimney visitors are little animals looking for a warm place to stay. A recently used fireplace creates a warm chimney that attracts birds and squirrels. These critters only want a cozy place to weather the upcoming winter, but this can cause some serious problems for you. Any kind of obstruction in your chimney prevents the smoke and other toxic gases from properly venting. As a result, these gases backtrack right into your home, which can have potentially deadly consequences like carbon monoxide poisoning. You can easily prevent this issue by having a well-fitted chimney cap installed.

Another purpose of the chimney cap is to keep water from leaking inside. It surprises some homeowners that water can actually cause extensive damage to your chimney. The water will rust the steel flue lining, causing it to deteriorate. This then exposes the interior of the chimney structure to water. If you have a masonry chimney, the water will absorb right into the structure and degrade the materials throughout the freeze and thaw cycles of winter. The chimney may eventually crack or even collapse. Water can also seep all the way into your fireplace and rust your damper assembly. You may even see water damage on the walls and ceiling surrounding your fireplace. All of this damage can add up to a lot of money in repairs, so spending a little upfront for a chimney cap does not seem like such a bad idea after all.

When your mason stops out to sweep and inspect your chimney, ask him or her to look at the chimney cap. It may be damaged or even missing completely, but your mason can give you the best advice on how to proceed.

Seal Your Chimney Flashing Before It’s Too Late

Summer has officially come to an end, and now it is time to look ahead to the exciting change of seasons. The colorful leaves and chilly weather has everyone in the season spirit. The upcoming holidays are also on a lot of people’s minds as the end of the year approaches. This is usually a happy time of year, and no one wants to think about keeping their roofs from leaking, or even about a roof that is already leaking. However, now is the best time to take care of any roof leaks because the frigid winters in the Hudson Valley make roof conditions too dangerous to work on until spring comes around again.

Chimneys are responsible for a surprising number of water leaks into the house. Without a chimney cap, water can enter directly through the top of the chimney. If the masonry is improperly sealed, water can travel through the brick and mortar, right into the house. While these issues deserve a column of their own, leaky flashing is the topic of today.

Flashing is a covering used to stop water from leaking beneath the roof shingles. It can be found anywhere the line of the roof ends, such as around dormers or sky lights. Chimney flashing prevents water from leaking in where the chimney protrudes from the roof. Generally made of aluminum, the flashing on a chimney is much more complex than flashing on other areas of the roof. It consists of four woven layers of flashing all sealed with mortar to prevent premature decay.

While the mortar that holds the flashing together holds up longer than other materials some nonprofessionals use on their flashing, it is not indestructible. If not maintained properly, mortar will eventually deteriorate. It is a porous material, so when exposed to water, the mortar absorbs it readily. Then, around winter time, the saturated mortar expands and contracts during the freeze and thaw cycle. This inevitably results in cracks, and in turn, a leaky roof. In order to prevent a leaky roof and to maintain the integrity of the flashing, you can have your mason seal the flashing around the chimney.

Applying a sealant to your flashing keeps the aluminum and the mortar out of direct contact with the elements. The waterproof sealant prevents water from seeping into the mortar or even into your home. For the ambitious do-it-yourself types, be aware that poorly serviced flashing will not last as long as properly maintained flashing, and it could even cost you thousands of dollars in water damage repairs.
