Brick Chimney Required New Flashing and Wood Sheathing
Older homes may need additional repairs done during the roof replacement process. In this project we repaired a large chimney that had that two major issues:
- The wood sheathing was rotting and
- The chimney flashings were worn out.
The first thing we did was replace the rotten roof sheathing because they can no longer support the weight of a roof, nor can it hold nails.
In addition, a cricket (wood saddle) was installed to redirect water from the high point of a roof in order to prevent pooling. A cricket is required when a chimney is wider than 24” and the roof pitch is 6/12 or greater.
To keep the entire area dry, we installed a layer of waterproof, self-sticking ice & water membrane around the base of the chimney.
The last step was to install the new flashings. In order to form a watertight seal, we used several types of flashings: V-shaped metal flashings, step flashings, cap flashings, and corner step flashings.
