Installation Guide

Manufacturers’ product lines continued to
broaden and, in 1988, the members changed
the organization’s name to the Cedar Shake &
Shingle Bureau. In the late 1980s, mill quality
control inspections were subcontracted to
independent, third party quality control
agencies.
Each year the Cedar Shake & Shingle
Bureau’s staff answer thousands of technical
questions and product selection queries. Our
proud history, quality reputation and
dedicated members provide excellent
TM
Certi-label cedar shingle and shake siding
and roofing products.
Certi-label Western Cedar shingles and
shakes manufactured by members of the
Cedar Shake & Shingle Bureau (“CSSB”) are
the only products labeled with the “Certi”
brand name. Certi-label Western Cedar
shingles and shakes are made by
experienced craftsmen who take pride in
their trade and the quality of their product.
Despite their varying sizes and sometimes
remote locations, member mills are bound
together by a rigid quality code.
Unannounced independent inspections
conducted by accredited third party agencies
ensure that product quality is maintained.
Products are inspected to conform with
various local, national and international
codes and standards (contact the CSSB for
specific details).
All CSSB member product has the mill's
distinctive Certi-label tucked under the
bundle strap or printed on the carton. Asking
for “the blue label” or “number one blue
label” is not specific enough: CSSB
members' products are the only ones with
the Certi brand name on the label.
Good workmanship is crucial to the integrity
of any sidewall system. Installers should
read this manual carefully and ensure that
they follow proper workmanship practices.
Certi-label Western Cedar shingles and
shakes are applied on walls in a different
manner than on roofs. The major point of
difference is in permissible weather
exposures - on walls the maximum weather
exposure is greater than it is on roofs.
A given area of wall, therefore, will require
less material than the same area of roof.

Application Notes
Note: This manual replaces all previous
versions of the “Cedar Shake and Shingle
Bureau Design and Application Manual
for Exterior and Interior Walls”
This manual is intended for use with Western
Red Cedar and Alaskan Yellow Cedar shingle
and shake applications only. Western Red
Cedar products manufactured by CSSB
members are labeled with the “Certi” brand
name. Alaskan Yellow Cedar products
manufactured by CSSB members are labeled
with “Yellow Cedar” at the top of their label.
For ease of reference this manual refers to
TM

understood to include both Western Red
Cedar and Alaskan Yellow Cedar products
manufactured by CSSB members.

Certi-label Western Cedar shingles and
shakes are the ideal exterior wall cladding
for new construction and remodeling. They
bring life in the form of beauty, texture,
durability, insulative quality, and low
maintenance to any building. Restyling with
Certi-label Western Cedar shingles or shakes
is easily accomplished, whether replacing
the previous wall material (re-walling) or
applying right over the existing wall (over-
walling).
Material for this manual has been compiled
from various authoritative sources, and
many of the construction methods shown
herein have been developed by the shingle
and shake specialists in both the United
States and Canada. The design and
application details and methods of
construction reflect current good building
practice. Other options are possible but
ensure that you check with your local code
jurisdiction for approval.
The information in this manual is
not intended to supercede local
building codes.
On June 9, 1915, at a meeting of the Trustees
of the West Coast Lumber Manufacturers
Association, it was agreed to establish a
branch of the association to serve those
members who manufactured shingles. Our
influence grew, and as we survived both the
Great Depression and World War II,
manufacturers continued their quality
commitment. In 1963 the organization
merged with the Handsplit Shake Bureau to
become the Red Cedar Shingle & Handsplit
Shake Bureau.
