We recommend regular chimney maintenance. Have a fireplace professionally
examined and clean the flue to keep this critical system in check. Chimney spark
arrestors, also called rain covers, are recommended to prevent water penetration
and prevent sparks from landing on the roof or other nearby combustible
material.
Chimney cap (or crown)
The chimney cap is the top element of a masonry chimney. This mortar will not
withstand years of weather abuse without cracking, chipping or deteriorating,
these situations allow water to penetrate the chimney. See
an example of a failed crown here.
Flashing
Flashing is the seal between the roofing material and the chimney. Flashing
prevents rain water from running down the chimney into living spaces. The most
effective flashing is made up of two elements, the flashing and the counter
flashing. This two element flashing allows both the roof and the chimney to
expand or contract at their own rates without breaking the waterproof seal in
either area. See an
example of a failed flashing here.
