Chimney Roof Leaks

Chimneys are often an overlooked part of the roof and many assume they’ll have no issues with them, but like everything they deteriorate over time and can cause chimney roof leaks. Chimney Leaks can occur for numerous reasons and can lead to major inconveniences in your home. Melbourne is no stranger to severe weather conditions, and masonry chimneys can be prone to water damage. Water damage can cause blockages to the chimney flue, damage the lining, and result in problems with bricks becoming loose and broken. Chimneys with water damage can not only be inconvenient, but also dangerous and impact the health of those who reside in your household.

A leaking chimney can cause damp within your house which can lead to both health problems and a lot of expense. It is thus important to keep not only your roof but your chimney well maintained. If any leaks or issues arise it is important to get it fixed as soon as possible to avoid costly fixes and ill health. There are multiple reasons your chimney may be causing roof leaks, all of which are preventable or fixable. Here are 4 reasons why you may experience roof leaks from your chimney:

  • Rain entering the chimney
  • Damage to the bricks and mortar
  • Broken or damaged chimney flashings
  • Cracked chimney crowns

Rain entering the chimney

Considering that a chimney is an opening in your roof, it may be obvious to state that sometimes water and debris may enter the chimney and cause issues. If rain enters the chimney it can seep into the bricks and mortar and cause damp and leaks. It is therefore important to have a chimney cover that protects your home from these risks. A cover can not only protect your chimney from rain but also from other debris and even animals. Debris and animals may cause a blockage in your chimney. A blockage may not only cause issues with chimney roof leaks and damp but can also cause a buildup of CO2 which can be very dangerous to you and your families wellbeing.

Damage to bricks and mortar can cause damp and leaks 

Bricks, while a solid and reliable building resource, are not immune to the effects of water damage. Masonry can be made of a variety of materials that can vary from provider to provider. Although Masonry is still strong, it can at times, depending on the materials, result in cracks in the bricks. These cracks can easily become filled with water and can cause damage to the structure, which may eventuate to a damp wet area. Even if the bricks and mortar are very solid, they will still break down over time. Cracks in the bricks that make up your chimney are a haven for water to sit and cause damage. Getting damaged bricks and mortar replaced to avoid damp and leaks is an investment worth considering, as it will save you time, money and health issues.

Damaged flashing may cause chimney roof leaks

Flashing tends to be applied to the base of the chimney where it connects to the roof. The purpose of flashing on your chimney and other areas of the roof is to make the area waterproof and sealed. If there are any gaps between your roof and chimney, or if flashing is not installed correctly, roof leaks can occur around this area. These leaks have the capacity to cause a decent amount of damage and should be attended to quickly. While well installed flashing is strong and should last for quite a long time, it will eventually deteriorate.

If your flashing deteriorates due to the weather or it being struck by debris, it could result in parts of the masonry becoming exposed and damaged. Keeping the flashing maintained could result in the avoidance of these issues. If you think your flashing may need replacing you can contact us for a quote today here, or call us on 0435 695 466.

Cracked chimney crowns can cause roof leaks

The purpose of the chimney crown is to protect the chimney from the rain, hail and snow. The chimney crown is the top part of the chimney, usually made out of cement. If the chimney crown is subjected to constant changes in hot and cold temperatures and a high volume or rain, it may result in it shrinking and expanding. Over time this can lead to small cracks in the crown. If these small cracks are detected early they can be treated and sealed, protecting you from leaks and damage. However, small cracks can lead to big cracks over time, and this can make the crowns purpose no longer possible.

Rain and other elements can enter the chimney and damage the bricks and mortar resulting in serious costly damage. Therefore, if you ever have a maintenance check on your roof or if any other issues are being attended to, make sure that the chimney is also checked over for these various issues so they can be fixed before they become more serious. 

What to do if you have chimney roof leaks

As you can see, your chimney may be susceptible to multiple issues, and it is important to keep these in check. A chimney is perhaps the riskiest part of a roof when it comes to roof leaks. It is therefore equally, or even more important, to check on your chimney regularly to avoid any issues. If you are experiencing any issues with roof leaks or dampness, it could be due to damage in your chimney. If you think your chimney may be damaged in any of the above ways, or want to get a professional roofer to take a look and put preventative measures in place, contact us here or call us on 0435 695 466 to get a quote and consultation today.

    I live in a single story Victorian house in Brunswick. The house has a brick chimney with an ornamental concrete surround at its’ top.
    Recently, one side of the surround broke off, damaging 7 tiles, which I have had replaced.
    The remaining 3 sides of the chimney surround will fall off in the none too distant future.
    Are you able to assist by removing the remains aspects of the surround & generally making safe the chimney please?
