The Cedar Shake & Shingle Bureau is very involved in building code work. Certi-label™ cedar products are manufactured to CSSB-97 grading rules, which have been adopted by the US International Building Code (IBC) and the US International Residential Code (IRC) and the National Building Code (NBC) in Canada. The CSSB is active in the Canadian Standards Association committee and is involved in the code change process prior to any changes being formalized. Certi-label™ shakes and shingles meet all national standards for shakes and shingles.

The following code bodies and manufacturing standards in the United States and Canada govern shake and shingle manufacturing and application:
  • American Society for Testing and Material (ASTM)
  • California State Fire Marshall (CSFM)
  • Canadian Standards Association (CSA)
  • Cedar Shake and Shingle Bureau
  • International Accreditation Service (IAS)
  • International Building Code (IBC)
  • International Residential Code (IRC)
  • National Fire Protection Association (NFPA)
  • Uniform Building Code (UBC)
All construction projects in the United States must meet at minimum IBC and IRC standards. Prior to beginning construction, homeowners and contractors should check with the local building official in their area to ensure that their project meets all code requirements and adheres to any local ordinances in place when applying roof or sidewall product.
