Neither cedar shake nor wood shingle is universally better: cedar shakes win on a thick, hand-split textured plane and last 20-40 years, while wood shingles lay flat, formal, and last 30-50 years, per the Cedar Shake & Shingle Bureau. Architecture and slope orientation decide.
Both are western red cedar, so the choice turns on three things: how each cuts and wears, what each costs to keep, and which one your Essex County roofline and NJ code path call for.
How Do Cedar Shakes and Wood Shingles Differ in Cut, Thickness, and Face?
Cedar shake is a thick western red cedar unit hand-split or taper-sawn into an irregular, textured face, while a wood shingle is the thinner same-species unit machine-sawn to a uniform thickness, per the Cedar Shake & Shingle Bureau.
Cedar shake reads as a rough plane with deep shadow lines and sells as hand-split-and-resawn or taper-sawn product, with the top grades cut from all-heartwood, edge-grain stock and graded against the standards the Cedar Shake & Shingle Bureau publishes. Each course sets over an air-spaced deck so the underside dries after rainfall, which is why a cedar roof reads as a series of shadowed, textured rows rather than a flat surface. The split-versus-sawn face is the defining difference between the two, not the species, since both are western red cedar prized for natural decay resistance.
Wood shingle is machine-sawn to even thickness so it lays smooth and flat across the roof plane for a tailored, formal roofline, the same species as cedar shake but distinguished by its sawn rather than split face. On a contributing historic structure, a wood-shingle replacement matches the original size, shape, texture, and exposure rather than an aged appearance, per NPS Preservation Brief 19, since historic shingles were themselves handsplit or sawn. That matching standard is why the choice between a split and a sawn face often follows the house rather than the homeowner's preference alone.
Which Cedar Roof Lasts Longer and Costs More to Maintain in NJ?
Wood shingles carry the longer rated life at 30-50 years and cedar shakes the shorter at 20-40 years, per the Cedar Shake & Shingle Bureau, against the InterNACHI life-expectancy chart's single 25-year 'Wood' row covering both.
Cedar shakes at 20-40 years degrade through moisture-driven cupping, edge splitting, and rot beneath cupped shakes, and the units need at least 1.5 inches of air space beneath them for drying, per the Cedar Shake & Shingle Bureau and NPS Preservation Brief 19. Wood shingles at 30-50 years lose service life fastest on north-facing, shaded slopes where moss and algae accumulate as prolonged moisture drives biological growth, per the Cedar Shake & Shingle Bureau. Both products share that moss and algae accumulation on shaded slopes, not just one, per the InterNACHI chart and NPS Preservation Brief 19.
Maintenance is the same for both: periodic fungicide and algaecide treatment at $0.15-$0.60 per square foot every few years, per HomeGuide, plus prompt replacement of cupped or split units. A flex test settles a cedar unit's condition, since a unit that cracks under light bending shows advanced degradation regardless of surface, per the InterNACHI chart.
Cost tracks closely between the two products. A NJ premium-material install runs $10-$20+ per square foot for either cedar shakes or wood shingles, and wood-roof repairs run $400-$1,800, averaging $750, per Angi, with small repairs at $100-$400 and larger repairs above $1,000, per HomeGuide. Because the install and repair ranges match, the longer 30-50-year shingle range against the 20-40-year shake range is what separates lifetime value, not a difference in price per square foot.
Which Cedar Roof Fits Your Essex County Home and NJ Code?
Cedar shakes suit textured, handcrafted facades such as Craftsman bungalows and rustic colonials, while wood shingles suit the formal, uniform rooflines of formal colonials and Cape Cods, per the Cedar Shake & Shingle Bureau and NPS Preservation Brief 19.
Cedar shakes read as handcrafted, their hand-split-and-resawn and taper-sawn grades casting deep shadow lines across the plane, while wood shingles lay flat for an orderly roofline. One more fastener rule applies to both: red cedar takes hot-dipped zinc-coated, aluminum, or stainless-steel nails, not copper, because a chemical reaction between cedar and copper shortens the roof's life, per NPS Preservation Brief 19.
The NJ Uniform Construction Code treats a full red-cedar re-roof, shakes or wood shingles, as ordinary maintenance on a detached 1- or 2-family dwelling, with no permit, inspection, or notice, per N.J.A.C. 5:23-2.7. On a commercial building, cedar work crosses out of that exemption once it exceeds 25% of roof area in 12 months, since the exemption covers only detached 1- and 2-family dwellings, per N.J.A.C. 5:23-2.7(c).
A local historic district adds one gate: cedar shakes or wood shingles in such a district need a Certificate of Appropriateness from the municipal Historic Preservation Commission before a reroof, per N.J.S.A. 40:55D-107. Glen Ridge's ordinance covers over 90% of the borough and Montclair codifies its review at section 347-136, though National or NJ Register listing alone places no restriction on a private roof replacement, per the National Park Service.
The decision comes down to fit, not a single winner: cedar shakes for a thick, textured 20-40-year plane on a handcrafted facade, wood shingles for a flat, formal 30-50-year roofline, both per the Cedar Shake & Shingle Bureau. Maintenance, install cost, and the NJ code path are the same for either.
