How to Identify Possible Chimney Damage

‘How do I know if my chimney is on fire?’ This might seem like a dumb question, but yet it happens so often! The reason why it is a common occurrence is because the soot and embers from the fireplace build up in your chimney flue. They get mixed together with the smoke and pushed up and against the inner sides of the chimney, which is called the flue. If the built up soot ends up catching fire in the flue, it rises upwards to the roof, where it then can quickly spread to the rest of the house. A lot of chumney roof fires occur with homes that have a chimney without a cap. While the cap is completely optional, it is an inexpensive add on that helps to reduce house fires as it prevents embers from being able to rise up and escape out of the open top.

The Two Types of Chimney Fires

Having a Protective Cap Helps To Properly Filter Our Smoke and Reduce the Risk of Chimney Fires

There are two types of chimney fires- slow burning and fast burning. You can notice that you have a fast burning chimney fire if you hear the sounds of a bonfire coming from inside the chimney, such as loud cracking and popping noises like those of embers bursting. Lots of thick black smoke will either be coming out of the top of your chimney or entering your home through the fireplace.

Slow burning chimney fires often damage more the sides of your chimney and can cause fire to escape from the side instead of the top. This is dangerous as it can result in the home next door being easily able to catch fire, too since the fire is low and slightly shifted sideways. Or it could easily spread across your property to your fencing and beyond, requiring you to get fence maintenance, as well. Look for heat damage on the top of your roof, such as warped metal fixtures like flashing, vents, or TV antenna. This indicates that the structures have constantly been damaged by intense heat over a prolonged period of time. If you notice that structures on the roof are black, this is the result of creosote, which is smoke and ash have combined with moisture to form an almost sap-like substance that clings to things.

Common Chimney Issues

  • The mortar around the chimney can crumble from water damage. This is dangerous because the brick or flue tiles that surround the chimney base can fall inside and get stuck, which creates a fire hazard.
  • The flashing around the chimney base often tend to come loose over time from water damage and can result in leaks.
  • A brown crown of the chimney can allow for rainwater to enter the chimney. Signs that the crown are broken are that the sheetrock or wallpaper near your fireplace have water damage.
  • A lot of chimneys can experience obstruction, whether it is from animals building nests inside, overhanging trees, or improper height requirements.
  • If the chimney does not have the proper ventilation to allow all the smoke to be released, it can build up and circle back into the house, resulting in carbon monoxide poisoning.

Can Chimneys Leak?

If the brick mortar or metal flashing at the base of your chimney has come loose, then yes, your chimney can leak. What causes chimney leaks? This is because the caulk and flashing sealant around the base starts to wear loose over time, allowing water to seep underneath the uplifted portions and through the roofing. The crown can also cause leaks, especially if it freezes and then thaws, allowing the melting water to drip into the house.

How Much Does it Cost to Replace a Chimney?

Small repairs to chimneys only cost around $200. If a complete replacement is required, prices can range from $1,000 to $10,000 depending if the fireplace has to be replaced as well. Does homeowners insurance cover chimney repair? Small and common repairs like fixes to the masonry and cover replacement are not covered by your homeowners insurance as they are viewed as normal wear and tear.

Your insurance will only maybe cover your chimney repair or replacement if catastrophic events like fire or collapse are involved. Even then, they may deny you as they could say that there was too much soot build up due to neglect of cleaning, or that the collapse could have been avoided from better maintenance. If a sudden Act of God like a tree falling on the roof or high winds blowing a lit ember up your chimney and starting a fire happen, only then will they usually over cover it.

Should You Clean Your Own Chimney?

While you can clean your own chimney to reduce the risk of soot building up, it is a dangerous job. Leave it to professional chimney sweeps who are trained to handle walking on roofs and thoroughly cleaning out the system without breathing in all the noxious fumes.
