Fascia Flashing
The purpose of fascia ashing is to support the shingle edge and to provide a drip edge to prevent water from
running back underneath the roong shingles and down along the fascia and soft.
Preformed eaves ashing/drip edge should be installed under the starter course of the shingle roong. The
extension of ashing supports the edge of shingles. If eavestroughs (rain gutters) are used, the ashing edge also
helps to direct the water into troughs. Fascia ashing protects both the soft and the fascia board, and provides a
drip edge at the bottom edge to direct water away from the building.
2. CAULKING
Use high-performance acrylic-latex, acrylic, acrylic-silicone, polyurethane,
polysulde or terpolymer rubber caulks or sealants to seal gaps around
windows, doors, corners, and other exterior joints that are exposed to
potential water intrusion. Pure silicone and clear caulks do not work
well on Western Red Cedar and are not recommended. Caulking is not
a permanent solution and as such requires regular maintenance. If not
inspected and maintained, caulking may fail and trap water, creating
severe moisture problems. Do not rely on it as the only barrier to
moisture penetration. Do not caulk areas that will prevent moisture
from escaping the wall cavity (e.g., under windows and around ashing).
3. ROOF AND GROUND CLEARANCE
Siding and Trim that extends down to a roof (dormers, second oors, etc.) and decks requires a minimum of a
2-inch gap to avoid wicking. Trim, such as water table or skirt boards must be a minimum of 6 inches above the
grade.
