Cedar Roofing and Sidewall Products
The Cedar Shake and Shingle Bureau® is a non-profit organization that promotes the use of Certi-label® cedar roofing and sidewall products. The Cedar Shake and Shingle Bureau® provides technical publications on the specification and installation of Certi-label® shakes & shingles in addition to providing free technical assistance for Certi-label® shakes & shingles.
These shakes have split faces and sawn backs. Cedar logs are first cut into desired lengths. Blanks or boards of proper thickness are split and then run diagonally through a bandsaw to produce two tapered shakes from each blank. Available in Premium Grade (100% edge grain) or Number 1 Grade (Up to 20% flat grain allowed in each bundle).
These shakes are sawn both sides. Premium and Number 1 Grades are the most common. Premium Grade is 100% edge grain, 100% clear and 100% heartwood. Number 1 Grade allows up to 20% flat grain in each bundle. Number 2 and 3 Grades are also available.
Produced by machine or in the same manner as tapersplit shakes except that by splitting from the same end of the block, the shakes acquire the same thickness throughout. Premium Grade only. (100% edge grain).
Produced by hand, using a sharp bladed steel froe and a mallet. The natural shingle-like taper is achieved by reversing the block, end-for-end, with each split. Premium Grade only. (100% edge grain).
The premium grade of shingles for roofs and sidewalls. These top-grade shingles are 100% heartwood, 100% clear and 100% edge grain. Available in 16" or 18" or 24" lengths.
Shake or shingle product used to cap the peak of a roof. The appropriate hip and ridge unit should be selected to match the adjacent shakes or shingles. However, in many areas, a tapersawn hip and ridge unit is used on both shake and shingle applications. Hip and ridge product type selection should be performed in accordance with the aesthetic look desired.
Also known as R&R products, these materials have the same specifications as Number 1 and Number 2 Certigrade® shingles, but they are machine re-trimmed for parallel edges and with smooth butts sawn at right angles where a uniform appearance is desired. They are primarily used for sidewall applications. Rebutted & rejointed shingles are also available with a smooth sanded face, with the length of the sanded face at a length greater than the maximum exposure.They are manufactured from 16", 18" and 24" lengths. R&R products are for sidewall applications only.
Machine grooved shingles are manufactured as a rebutted & rejointed shingle with one face striated for a length greater than the maximum exposure. Machine grooved products are for sidewall applications only, and are remanufactured from 16", 18" and 24" shingles.
These shingles are 5" wide and are manufactured from 16" and 18" lengths. An 18" length, 96-piece carton will cover 25 square feet at 7 1/2" exposure. Certi-Cut® shingles can also be custom produced to meet individual design specifications.
Historical Applications Accuracy
It is of prime importance to replicate the original building. A challenge comes with finding historically accurate products and meeting current building codes. Years ago, people did not use products such as plastic shakes, vinyl siding, and concrete tiles, Wood was the building material of choice, and wise project leaders are still specifying wood. The CSSB can help with period-correct specification of cedar shakes or shingles, assist with application information, and source the proper finishing products relevant to the era of specific historical projects. The CSSB also has contacts in the building official community and highly recommends you contact them for project approval guidelines, possibly including variances for specific historical projects.
Custom Dimensions Available
CSSB member manufacturers offer specialty products to meet the needs of historic project managers. Dimensions that exceed “stock" sizes can be sourced through the CSSB's extensive member network. Key historical products that are available: Tapersplit shakes, in various lengths up to 36″ and beyond. Straight Split shakes, in various lengths up to 36″ and beyond (Straight Split shakes are also known as Barn shakes). Shingles are available in various thicknesses upon request.
Roofing and sidewall system integrity depends upon the quality of the product used. Ensure your cedar shakes and shingles meet grading rule requirements, as required by building codes. Certi-label® products undergo third party inspections and each bundle is clearly labeled with the appropriate product grading information.

Ashford, Connecticut is home to a very special 5-acre parcel of land. Originally part of a larger 60-acre estate, the property contains a house once used for 19th Century summer parties. Playing horseshoes and enjoying family gatherings were popular pastimes, proven by antiques, historical documents and photos found on site. From 1929 -1979, the home stood vacant, boarded up and quite forgotten, likely to avoid inheritance taxes. As the years passed, sheep were raised on the surrounding land. It seemed inevitable that the home was destined to eventually fall prey to a bulldozer.
Ardent fans of the traditional English cottage will no doubt appreciate this gem of a home located just outside Minneapolis, Minnesota. In the midst of a professional community, 10 minutes from the city center, sits this Cotswolds-inspired home. Built to replicate one of the famous English yellow fieldstone cottages, tough Minneapolis winters required a roofing product a bit more weather resistant than traditional thatch. Certi-label® cedar, long known for its weather resistance, was the perfect choice for the design and protection of this lovely home.
An exceptionally busy set of homeowners decided that their residence needed a fresh decor plus a new roof. This Chicago suburban home was originally roofed with 24" x 1/2" medium shakes.

It was on a sun-drenched day in 2012 when CSSB District Manager Tony Bonura and Director of Operations Lynne Christensen paid a visit to the magnificent Lawson Tower. On approaching the town of Scituate, the structure looms ahead, dwarfing everything in sight. Lawson Tower is a project that really defies the ordinary. 153 feet tall at the tip of the wind-vane pole, it has 123 narrow, winding stairs, 240 squares of Certigrade® Western Red Cedar (WRC) shingles and 108 years of history. What once shielded a wealthy woman from an eyesore, is now listed on the National Register of Historic Places.

This historic home and accompanying carriage house are listed on the United States National Register of Historic Places, owned by the State of Washington, and operated by the Eastern Washington State Historical Society (EWSHS). Both buildings were reroofed in the summer of 2016 and the Cedar Shake and Shingle Bureau (CSSB) was part of the project right from the start.
Set deep in the heart of Lancaster County,Pennsylvania, is a project that rapidly attained the title Celebration of Wood. True to the 140 acre farmland property's roots, this project was designed from the start to showcase the natural beauty of forest products.
This has been an intensive project with a large team of craftsmen and skilled trades persons, all organized to complete the work on a “fast-track" schedule. Even with such a demanding work pace, dedication to exhibiting the beauty of wood provided a common bond that brought out the best in each of the crew members. Top quality Certi-label® roofing products were used. Premium Grade Certi-Sawn® Yellow Cedar, 18" x 5/8" tapersawn shakes were manufactured by Waldun Forest Products Partnership. Certi-Ridge® hip and ridge units were manufactured by G & R Cedar Ltd. Certi-Last® preservative treatment was provided by Western Wood Preservers, Ltd.

The town of Hull, Massachusetts, is situated on an arrow peninsula just South of Boston Harbor. Locals are determined to preserve Hull's heritage as the founder of seafarer lifesaving efforts. The Hull Lifesaving Museum, former US Coast Guard Point Allerton Station, is a prime example of a character building with precious ties to the past. From 1880-1969, this building housed lifesaving crews who chanced their own lives to save mariners at risk from the sea's jagged rocks.
Pursuing History with a Passion. At the street, bordered by a forest and a colonial-era, stone wall made about 1740, stands a saltbox design home currently undergoing a complete exterior and interior makeover. The homeowners are clearly fascinated with United States history, and wanted their remodel project to be an authentic recreation of a circa 1750 home. The Cedar Shake and Shingle Bureau (“CSSB") was privileged to have the opportunity to visit this jewel of a project. Of all the projects the CSSB team has seen over the years, this one stands out due to the homeowners' relentless drive for quality and historical accuracy.
