Height Requirements for Chimney Installations in Ham Lake

Tuesday, May 29th, 2012

When contemplating the look of your chimney installation in Ham Lake it is important to follow the specific height requirements set by the NFPA (National Fire Protection Association).  These height requirements were established to distance the top of your flue from your home’s roof to reduce the amount of heat that your roof is exposed to.  The obvious reason for these requirements is if the top of the flue is too close to the top of your home, the heat could catch your roof on fire.  A not so obvious reason for these height requirements is if the fireplace does not have a sufficient distance from the fire pit to the top of the chimney flue, the smoke will not be sucked up towards the chimney.

The height requirements for a typical chimney, otherwise known as a masonry chimney, is the top of the flue must be 10 feet horizontally from any portion of the roof, and the top of the chimney must extend 3 feet from the roof, where the chimney protrudes.  Typically a chimney inspection professional from 2nd Generation Chimneys should check these distances, but the best way to check if your chimney clears the 10 foot distance between the top of the flue and your roof is by placing a tape measurer on top of your chimney, extend the tape straight out to 10 feet, and make sure you can not touch any portion of your home with this extended length.  You can also measure 3 feet from the top of your flue down to the roof, where your chimney emerges, to see if that height requirement is fulfilled.

If you find out that your chimney flue does not meet the height requirements for the safety of your home please contact 2nd Generation Chimney.  We will be able to fit your flue with a chimney height extension.

Common Chimney Repairs in Plymouth

Wednesday, March 7th, 2012

Your chimney in Plymouth may seem like a simple component of your house, but it needs a lot of maintenance and even with regular checkups, you might find yourself in need of one of these common chimney repairs.

Cracking or Falling Bricks

During the colder winter months, your chimney absorbs water and then freezes, holding that water inside, causing the mortar and bricks to expand. The water then thaws and the bricks are weakened. Enough cycles like this and the bricks will start to crumble and fall out of the chimney. To stop this from happening, a contractor will place water sealant on the bricks in your chimney to keep them from succumbing to water damage. If properly done, this stops 99% of all moisture from entering your chimney.

Crown Problems

The crown on your chimney can be insufficient or not sealed properly, resulting in water coming through onto your fireplace or mantel or leakage in the firebox. If you notice any moisture inside your home, either along the chimney structure itself or on the firebox or mantel, it is most likely an issue with the crown.

Flashing

When the roof is done on your home, flashing is placed around the chimney to seal the joints between masonry and shingles. This keeps any water from getting between the two and leaking into your home. If you notice water on your ceiling or on any walls adjoining the chimney, this may be the problem and can be fixed relatively easily by a roofer.

Flue Damage

Even with the right flue lining installed, damage can occur over time from regular use. The flue liner can crack or break or it can become blocked by creosote or other debris over time, especially if you don’t have a chimney cap to block things from entering on top of your house. Regular flue liner cleaning should take care of these problems.

If you are concerned about your chimney or the chimney liner, make sure to call 2nd Generation Chimneys to inspect it for these or other possible problems. Most chimneys will have small, easily repaired problems over their lifespan – no need to let them get any bigger.
