Characteristics
Renowned for the quality of our products, we manufacture natural, KD (kiln-dried) and factory-stained shingles
in our own facilities. With its numerous properties (e.g. decay resistance, high insulation, lightness, etc.), white
cedar (thuya occidentalis) is the ideal choice for roofing or exterior siding. Its natural oils protect against
mold, moisture and insects, thereby ensuring a longer life. Cedar shingles age beautifully, even when left
untreated. They enhance the beauty of a home while blending perfectly with other natural materials such as stone
and brick.

Choice of Shingles
Resquared and Rebutted (R&R) Shingles
Our Extra ‘’A’’ and Clear ‘’B’’ grade (also available in 2nd Clear ‘’C’’) shingles are R&R.
They are distinguished by their perfectly straight butt, perpendicularly square with the
shingles’ two fully parallel sides. As a result, SBC R&R shingles ensure enhanced beauty
and substantial savings in installation time and costs.
Kiln-Dried (KD) Shingles
Our dehumidification kiln enables us to manufacture shingles (grades A, B and C)
having superior stability. When selected for the kiln, the shingles are prepared to
ensure uniform dryness (approx. 12% humidity) and to prevent cracking. A 30 years
warranty against wood decay is available on our KD and pre-stained shingles. For
optimal protection, all of our KD shingles are boxed.
Weathering Stained Shingles
SBC uses PPG/Olympic’s Weathering Stain in order to offer silvery gray ready-
to-install shingles. In fact, this product accelerates the wood’s natural weathering
process while ensuring an attractive, uniform, low-maintenance finish. Our KD
shingles are individually dipped in the stain for maximum protection. The stain’s
unique water-repellent formula provides improved wood stability and resistance to
cracking, blistering and peeling.
Factory-Stained Shingles
To complete our product line, we also offer shingles
that have been factory-stained with Olympic Machinecoat™,
a 100% acrylic coating. Available in an unlimited range of solid or
semi-transparent colors, these shingles are suitable for virtually all climates. Our
factory-coating technology ensures full coverage of all surfaces of the shingle,
producing an attractive, even finish, and minimizing shrinking and cupping.
In collaboration with PPG/Olympic®, we offer a long-term warranty program
against cracking, flaking and peeling: 10 years, for 1 coat; and 25 years for
2 coats. Our factory-stained shingles offer the best of both worlds: the natural beauty
of real wood and the durability of a pre-stained product.
