Chimney Flashing 101
Chimney flashing is the material that is fitted around the base of a chimney, sealing off the gap between it and the roof.
Flashing is typically installed in two sections: an L-shaped piece, which lies against the chimney and the roof; and a flat piece, which covers the top of the L-shaped section.
When installed and secured correctly, chimney flashing will prevent a lot of problems.
Issues with Damaged Flashing
Over the years, flashing can become damaged. Some of the causes include:
- Lightning strikes
- Powerful winds
- Old age
When flashing is compromised and proper chimney flashing repair work is neglected, the following three serious problems can occur.
Masonry damage below the roof line
Water pouring down through damaged flashing can begin a cycle of deterioration in your “hidden” chimney masonry.This is a big problem, because you can’t see what’s going on with your chimney’s internal bricks and mortar. If the problem isn’t addressed, mortar joints that hold the bricks together can begin to crumble. The bricks themselves can begin to crack and spall.
The end result is a chimney that will need to be rebuilt, either partially or completely. This is an expensive job that you want to avoid if at all possible.
Building material damage
Free-moving water below your roof can affect your ceiling, attic, wall boards, rafters and other parts of your home, creating destructive force when it’s allowed to sit in contact with certain materials.
As with chimney masonry damage, building-material rot isn’t something the average homeowner will be aware of until serious damage has occurred, which is how chimney flashing repair/replacement can help.
Mold / Moss growth
Damp, unventilated spaces are ideal for mold growth. Some mold is harmless; other molds can cause significant health risks for humans and animals.
As with the other two flashing-related issues above, mold growth in the interior spaces of your home won’t be noticed right away. The longer mold grows, the larger the outbreak will be.
Black mold is a species of this fungus that has been shown to cause major upper-respiratory problems and even cancer and death. You do not want any kind of mold growing in your home.
