Most
masonry materials are porous and will absorb large amounts of water.
Common brick is like a sponge, absorbing water and wicking moisture
to the chimney interior. Defective mortar joints or the use of improper
mortar or brick can greatly increase the tendency to absorb and
convey water to the interior of the masonry chimney.
Preventing Water Damage
Chimney caps, also called rain covers, are probably the
most inexpensive preventive measure that a homeowner can employ
to prevent water penetration and damage to the chimney. Caps have long been recognized as an important safety and
damage prevention component.

Proper
Flashing
Flashing is the sheet metal that seals out water where
your chimney meets or passes through the roof. It is a critical
seal in making certain your chimney is weather tight. Proper flashing
will be embedded into the masonry and consist of both step
and counter flashing along with an ice and water shield membrane
underlayment.
Flashings are custom made at the job site to insure a proper tight
fitting seal between your roof and chimney. When done properly by
our experts, this flashing will keep water out of your house for
many years.
