New Roof Construction Manual
Cedar Shake & Shingle Bureau
History
This manual is intended for use with Western
Red Cedar and Alaskan Yellow Cedar shake
and shingle application only. Western Red
Cedar and Yellow Cedar products
manufactured by CSSB members are labeled
with the “Certi” brand name. The species is
indicated by either “Yellow” or “Red” Cedar at
the top of the label. For ease of reference this
TM
manual refers to “Certi-label Western Cedar”
and the term is understood to include both
Western Red Cedar and Alaskan Yellow Cedar
products manufactured by CSSB members.
Material for this manual has been compiled
from various authoritative sources, and many
of the construction methods shown herein
have been developed by the shake and shingle
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.
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 Certi-label™
cedar shake and shingle roofing and
siding products.

Certi-label Products
Cedar shakes and shingles manufactured by
members of the Cedar Shake & Shingle
Bureau (”CSSB”) are the only products
labeled with the ”Certi” brand name.
Certi-label cedar shakes and shingles 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).
Each bundle of product has the mill’s
distinctive Certi-label tucked under the bundle
strap. 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.
Please Note: ONLY experienced professionals
who follow proper safety and workmanship
practices should implement the information
contained herein.
Note: This manual replaces all previous
versions of the “Cedar Shake and Shingle
Bureau Design and Application Manual
for New Roof Construction.”
