Cedar shakes and shingles manufactured by Cedar Shake & Shingle Bureau (CSSB) members are the only products labelled with the Certi brand — each bundle carries the mill's distinctive label as a mark of certified quality.
Premium shingles are 100% heartwood, 100% clear, and 100% edge grain — available in 406mm, 457mm, and 610mm lengths in Western Red Cedar, Alaskan Yellow Cedar, and tapersawn and handsplit shake profiles.
Fully compliant with New Zealand building requirements — backed by BPIR Class 1, PASS certification, CertiGrade Bureau certification, Harrison Grierson compliance, and CCA treatment documentation.
Cedar Shingles & Shakes Overview
The Building Agency provides the premium grade of cedar shingles and shakes for roofs, gable ends, and sidewalls — 100% heartwood, 100% clear, and 100% edge grain. Architects don't merely engineer a building; they envision its complete form in all its visual splendour. When only a cedar roof will deliver the desired look, Certi-branded shingles are the specification to reach for.
Timber shakes imbue many of the attractive qualities of shingles but with a more rustic and natural appeal — a hand-cut appearance that truly reflects nature's random design. Available in Western Red Cedar and Alaskan Yellow Cedar across handsplit, tapersawn, and shingle profiles.
Colour Range
Cedar shingles and shakes are available in Pine, Western Red Cedar, and Alaskan Yellow Cedar — in handsplit, tapersawn, and shingle profiles.
