What this calculator estimates

This calculator gives you a line-by-line installed 2026 US price for a cedar shake or cedar shingle roof, whether you are choosing Western Red Cedar (the default), Alaskan Yellow Cedar (premium dense), or Eastern White Cedar (budget). The calculator follows the line-item structure that Cedar Shake & Shingle Bureau (CSSB) member contractors use on real quotes:

  • Cedar material — selected by species, grade (Blue / Red / Black Label), and cut (hand-split, taper-sawn, sawn shingle)
  • Tear-off — removing the existing roof down to the deck
  • Underlay — synthetic or felt underlay (not standard felt under cedar — high-temperature self-adhered preferred)
  • Stainless or hot-dipped galvanized nails — corrosion-resistant fasteners (cedar tannins eat regular galvanized)
  • Cedar Breather elevated mat — ventilated airspace so cedar dries from below
  • Treated timber batten + counter-batten — alternative to Cedar Breather (some installs)
  • Ridge cap — cedar or metal ridge cap per linear foot
  • Open copper or painted-metal valley — preferred treatment for cedar per linear foot
  • Fire-retardant treatment uplift — Class B (+18 to 22%) or Class A (+28 to 35%) factory-treated bundles
  • Permit, disposal, and weekend premium

A $520 minimum service-call floor applies in most US cedar markets — Boston, Minneapolis, Chicago, Portland OR, and Seattle — even small cedar repairs require a two-person crew with stainless nails, cedar hooks, and proper safety equipment.

How to use it

  1. Enter roof area in square feet. For a typical home this is 1.10x to 1.40x your living-area footprint due to pitch.
  2. Pick species — Western Red Cedar (default), Alaskan Yellow Cedar (premium), or Eastern White Cedar (budget).
  3. Pick grade — #1 Blue Label is the only grade approved for primary residential roofs in most codes.
  4. Pick cut — hand-split & re-sawn (textured), taper-sawn (uniform), or sawn shingles (finer, layered).
  5. Set fire treatment — none (BAL-LOW areas only), Class B, or Class A (WUI zones).
  6. Set scope — spot repair (15% of area), partial replace (45%), or full reroof (100%).
  7. Set storey count — single-storey 1.0x, two-storey 1.2x, three-storey 1.45x.
  8. Set access difficulty — easy (drive-up) is 1.0x, moderate (rear garden) 1.1x, hard (lift required) 1.3x.
  9. Enter ridge cap and copper valley in linear feet.
  10. Toggle tear-off, underlay, stainless nails, breather mat, batten, permit, disposal, weekend premium and any extra labour hours.

Cost drivers

Grade premium. #1 Blue Label is the only grade most building codes accept for primary residential roofs. #2 Red Label is 20 percent cheaper but is for outbuildings and sidewall only. Non-graded cedar from box stores at 30 to 45 percent below Blue Label typically contains sapwood and fails within 8 to 12 years — no warranty covers it.

Cut style. Hand-split & re-sawn shakes give the most visible texture and command 10 to 14 percent over taper-sawn. Sawn shingles (perfections) cost 22 to 28 percent less than hand-split shakes but require a steeper minimum pitch of 4/12 and give a finer, Cape Cod appearance.

Fire-retardant treatment. Class B factory pressure-treatment (CCA) adds 18 to 22 percent and is acceptable outside WUI zones. Class A treatment (NCFR or Hi-Char) is required in California Chapter 7A WUI zones, Oregon, Washington, and Colorado WUI; it adds 28 to 35 percent. Both require factory bundles with UL stamp — field-spray retardants void the rating.

Ventilation under cedar. Cedar Breather mat at $0.85 to $1.05 per sq ft is non-negotiable on solid-sheathed roofs. Skipping it drops service life from 30+ years to 12 to 18 years and voids manufacturer warranty.

Time of year. Cedar installs best in dry weather above 40°F and below 90°F. Schedule cedar work for late spring through early fall in northern climates; year-round in coastal CA, NC, FL, and HI is fine.

Roof complexity. A simple 4/12 to 8/12 gable installs fast. Cut-up roofs with multiple dormers, valleys, hip-and-ridge transitions, and chimneys add 25 to 45 percent vs simple gable because every transition needs copper flashing in linear feet and slows the crew.

US code, standards, and certifications

  • IRC 2024 R905.7 — Wood shingle and shake requirements (minimum pitch, head-lap, fastening, underlayment, ventilation).
  • CSSB Installation Manual — Cedar Shake & Shingle Bureau is the industry reference; 2024 edition.
  • UL 790 / ASTM E108 — Fire test of roof coverings (Class A, B, or C rating).
  • California Building Code Chapter 7A — WUI zone mandates Class A roof assemblies.
  • ASTM F1667 — Driven fasteners standard (covers stainless and hot-dipped galvanized nails).
  • OSHA 29 CFR 1926.501 — Fall protection above 6 ft.

Use a CSSB-member contractor for any cedar project — the trade body operates the only formal cedar-roofing certification in North America and offers workmanship-warranty mediation.

Diagnostic step-by-step before quoting

  1. Verify the deck is sound — open soft spots from the attic side. Cedar projects often turn into partial deck-replacement projects ($60 to $90 per 4x8 sheet of OSB or plywood installed).
  2. Check WUI status — search your address on Cal Fire FHSZ Viewer (California), Oregon Department of Forestry WUI Map, or your state equivalent. WUI status drives Class A vs Class B requirement.
  3. Insist on the CSSB Blue Label stamp — visible on every bundle delivered. Non-stamped cedar has no warranty.
  4. Get three CSSB-member bids that itemize cedar grade, cut, fire treatment, underlay, Cedar Breather, copper flashings, and permit as separate line items. Lump-sum bids hide cost drivers.
  5. Confirm warranty terms — manufacturer material warranty is typically 30 years on #1 Blue Label WRC untreated, 50 years on Class B treated, 50 years on Class A treated. Installer workmanship warranty should be at least 10 years.

Avoiding scams and overcharging

Door-knocker roofers occasionally push cedar replacement when only individual shakes need replacement or a few stainless nails need driving. Red flags include claims that “the entire cedar roof needs replacement” when only the south and west elevations are degraded (sun-bleached but structurally sound), refusal to itemize fire treatment grade, no CSSB membership, no proof of $1M+ general liability insurance, and cash-only or wire-transfer demands. Reputable cedar roofers in 2026 carry $2M general liability, $1M auto, $500K worker compensation, and are CSSB members. Ask for the CSSB member number and verify it directly at cedarbureau.org.

Frequently asked questions

How much does a cedar shake roof cost in 2026 in the US?
Most US homeowners pay $8 to $15 per sq ft installed for a Western Red Cedar shake roof in 2026, all-in with tear-off, synthetic underlay, stainless or hot-dipped galvanized nails, Cedar Breather mat, treated battens, ridge cap, open copper or pre-painted metal valley, and a permit. A 2,000 sq ft single-storey home with #1 Blue Label hand-split & re-sawn shakes lands around $28,000 to $38,000. Taper-sawn shakes save 10 to 14 percent, sawn shingles save 22 to 28 percent. Alaskan Yellow Cedar runs 25 to 30 percent more; Eastern White Cedar is 18 to 24 percent cheaper. Class A fire-retardant treatment adds 28 to 35 percent.

Western Red, Alaskan Yellow, or Eastern White cedar — which should I choose?
Western Red Cedar (WRC, Thuja plicata) is the default. Sourced from coastal British Columbia and the Pacific Northwest, it is naturally rot-resistant (heartwood) and has a 30 to 50 year service life untreated. Alaskan Yellow Cedar (AYC, Callitropsis nootkatensis) is the densest and most durable, with 50 to 70 year service life and the highest resistance to splitting under heavy snow load — it is the heritage-correct choice in the Pacific Northwest and Alaska. Eastern White Cedar (EWC, Thuja occidentalis) is sourced from Quebec, Maine, and the Great Lakes, costs 18 to 24 percent less than WRC, and has a 25 to 40 year service life — it is the value choice for inland markets where moisture pressure is lower. For 90 percent of US homeowners, #1 Blue Label WRC hand-split & re-sawn is the right combination of cost, availability, and curb appeal.
What is the difference between #1 Blue Label, #2 Red Label, and #3 Black Label cedar?
These are the Cedar Shake & Shingle Bureau (CSSB) grading certifications. #1 Blue Label is 100 percent clear heartwood, 100 percent edge grain, no knots, no sapwood — the only grade approved for primary residential roofing under most building codes. #2 Red Label allows 10 inches clear (a small amount of flat grain and minor defects above the 10 inch line) and is acceptable for sidewall and outbuilding roofs but not most residential primary roofs. #3 Black Label is undercoursing and utility grade — sheds, barns, and starter courses only. Insist on the CSSB Blue Label stamp visible on every bundle; pricing for non-graded cedar is typically 30 to 45 percent below Blue Label but has no warranty and may contain sapwood that fails within 8 to 12 years.
Hand-split & re-sawn shakes vs taper-sawn vs sawn shingles — what is the difference?
Hand-split & re-sawn shakes have a textured split face (split with a froe) and a sawn back. They are 1/2 to 3/4 inch at the butt and give the most rustic, dimensional appearance. Taper-sawn shakes are sawn smooth on both sides, 1/2 inch at the butt, and look more uniform — they cost about 10 to 14 percent less and install slightly faster. Sawn shingles (perfections) are 3/8 inch at the butt, smooth both sides, and used on steeper Victorian and Cape Cod homes for a finer, layered look — they cost 22 to 28 percent less than hand-split shakes but require a steeper minimum pitch of 4/12. For most modern American homes wanting visible texture, hand-split & re-sawn Western Red Cedar #1 Blue Label is the default.
Does my house need a Class A or Class B fire-retardant cedar roof?
Yes if your home is in a Wildland-Urban Interface (WUI) zone in California, Oregon, Colorado, Arizona, Texas, or Nevada. California Building Code Chapter 7A mandates Class A roof assemblies on new construction and major reroofs in WUI zones; Oregon and Washington have similar state codes. Class B (pressure-treated with CCA at the factory, 50-year exposure rated) is acceptable in most non-WUI areas and adds 18 to 22 percent. Class A treatment (NCFR or Hi-Char factory pressure-treatment) is required in WUI zones and adds 28 to 35 percent. Both treatments require re-application of preservative to all field-cut edges and require factory replacement, not field-applied spray retardants which void the rating. Always specify factory-treated bundles with the UL Class A or B stamp and a 30 to 50 year warranty.
Why does cedar need a Cedar Breather or elevated batten under it?
Cedar must dry from both faces. If laid directly on solid sheathing with synthetic underlay between, moisture trapped against the underside causes rot from below — a documented failure mode that drops cedar service life from 30 plus years to 12 to 18 years. The 2024 IRC R905.7 (cedar shingle and shake provisions) and the CSSB Installation Manual both require a ventilated airspace under cedar on solid-sheathed roofs. Solutions are Cedar Breather (Benjamin Obdyke 1/4 inch nylon mesh, $0.85 to $1.05 per sq ft installed) or 1x batten on 2x counter-batten over the underlay. Open skip-sheathing (1x4 spaced) is the traditional method that achieves the same drying. Skipping this step is the most common cause of premature cedar failure and is excluded by virtually every cedar manufacturer warranty.
How long does a cedar shake roof installation take?
A 2,000 sq ft single-storey full reroof with hand-split & re-sawn Western Red Cedar Blue Label shakes takes 7 to 11 working days with a 3-person crew, weather permitting. Taper-sawn or sawn shingles are about 15 percent faster because the bundles are dimensionally consistent. Multi-storey homes with valleys, dormers, hips, and chimneys add 30 to 50 percent. Fire-treated Class A bundles install at the same rate but require additional sealant on field cuts. Cedar should be installed in dry weather above 40°F and below 90°F; very dry weather can cause initial cup-and-curl that subsides within 4 to 6 weeks of natural humidity cycling.
What is the minimum and maximum roof pitch for cedar?
Cedar shakes require a minimum pitch of 4/12 (about 18 degrees) per 2024 IRC R905.7. Below 4/12, water sits in the keyways between shakes and accelerates rot. Sawn shingles can go down to 3/12 with double underlay but most contractors will refuse below 4/12. There is no maximum pitch — cedar is used on church steeples and Victorian turrets at pitches over 18/12 (60 degrees). The traditional optimum is 8/12 to 12/12, which sheds water and snow quickly and is the look most homeowners associate with classic cedar roofs.
