Every year we get phone calls from customers who have a leak around their chimney.
Why is this the case?
The main reason is that typically, the chimney is the most technical portion of the roof.
Anyone can slap shingles down, but it takes a trained professional to properly flash a chimney in a way that will withstand the test of time and Michigan weather.
A properly flashed chimney will have the following components:
- Ice and Water underlayments
- Step Flashing
- Head Flashing (or a saddle)
- Apron Flashing
- Counter Flashing
If any one of these is missing or improperly installed, you will be subjected to leaks at or around your chimney.
This must be what they were thinking when they do that. There are a couple problems with this method:
- Tar shrinks over time and will separate
- Adhering the chimney to the shingles will cause a premature failure because the framing/shingles need to move independently from the masonry.
A properly install chimney flashing system will have step flashing that is attached to the roof deck and counter flashing that is independent and attached to the masonry chimney. This allows the two to move against each other while maintaining a water barrier.
Caulk is not the answer.
Often when we inspect roofs we see attempted repairs around chimneys where someone added gobs of goop in an attempt to stop a leak. Stop and go no further! Caulk is a Band-Aid and not a permanent solution. Although a properly installed chimney flashing system will consist of some joint and termination sealant (not tar!) it is placed in specific locations, mainly where the counter flashing meets the masonry. The metal is what flashes your chimney, not a tar that will shrink and split.
