The importance of home maintenance is something every homeowner realizes at some point of time or the other. The roof is an important part of your house, and it should be quickly attended to if you suspect it needs urgent repairs. Now, if you ever notice damage to your roof or ceiling, one of the problems could be a leaky chimney. Accumulated moisture in the chimney system leads to problems like mold growth, deteriorating bricks and mortar and also wood rot.
If it’s not fixed, it could lead to improper functioning of the chimney that can further escalate into serious issues in the future.
What Causes the Chimney Leaking Problems?
Whenever there is an issue with the roof because of a leaky chimney, it is necessary to identify the source of the issue. Here are some of the most common issues:
With time, the roof shingles and the flashings cracks, require replacement. Initially, there is only a small leak but the problem aggravates when the weather conditions get extreme.
Faulty Flashing: The use of wrong techniques during flashing installation is another cause of leaking chimneys. Step flashing is important because it creates a robust barrier, preventing the water to get through. Now, step flashing must be nailed onto the roof instead of against the wall. On the other hand, counter flashing is what needs to be attached to the wall. When this process is not followed as it should be, problems might show up.
Dried Up Sealant: There might be a crack in the sheet metal installed for the purpose of ensuring that the connection between the chimney and roof is watertight. Also, the sealant dries up over time and when they are damaged, water starts seeping through into your home. You should reach out to a professional roof repair company to get the sealant reapplied.
Waterlogging is yet another problem that leads to the chimney leaking issue. This happens when the shingles are not placed on the roof in the way they should which leads to the water build up right behind the chimney.
Chimney Flashing: a Solution to Leaking Chimneys
So, while the causes of leaking chimneys can be one or many among the ones mentioned before, the best solution to the problem is chimney flashing. Chimney flashing is made out of any of these materials: galvanized steel, stainless steel, lead, copper or lead-coated copper. The choice of material used will depend on where you live, the roofing material of your home, the size and shape of your chimney and the weather that your area is regularly used to.
The purpose of chimney flashing is to act as a seal at the very point where the roof and the chimney meets. The installation takes place in three steps:
- A base or step flashing, which is an L-shaped flashing extending under the shingles and bending up against the chimney sides
- Counter flashing, which involves a metal piece covering the vertical part of the base flashing. It is embedded into the chimney mortar joints and seals the upper part of the base flashing
- Cricket or saddle is triangular in shape and it is required to be installed to deflect snow or water around the chimney
