may be used in either manner if adequate nailing
areas are provided. Figure 6-52 shows a method
of vertical siding application.
Masonry veneers are used effectively with
wood sidings in various exterior finishes to
enhance the aesthetic appearance of the structure.
Other non-wood materials, such as stucco or a
cement plaster finish, are favored for an exterior
cover because they require a minimum of mainte-
nance. Plastic films on wood sidings or plywood
are also used because little or no refinishing is
necessary for the life of the building.
Flashing
FLASHING is specially constructed pieces of
corrosion-resistant metal or other materials used
to protect buildings from water seepage. Flashing
should be installed to prevent penetration of water
and other moisture in the form of rain or melted
snow at the junction of material changes,
chimneys, and roof-wall intersection. Flashing
should also be used over exposed doors, windows,
and roof ridges. Figures 6-53 through 6-57 show
areas or locations in which some type of flashing
is required.
Flashing materials used on roofs may be
asphalt-saturated felt, metal, or plastic. Felt
flashing is generally used at ridges, hips, and
valleys. However, metal flashing made of
aluminum, galvanized steel, or copper, is con-
sidered superior to felt.
