What this calculator estimates

This calculator gives you a line-by-line installed 2026 US price for a composite (synthetic slate, shake, or tile) roof, whether you are speccing DaVinci Roofscapes (the market leader), EcoStar by Carlisle SynTec (LEED choice), Brava Roof Tile (lightest), Inspire by Boral (West Coast architect favorite), or F-Wave REVIA (budget). The calculator follows the line-item structure that NRCA composite-certified contractors use on real quotes:

  • Composite material — selected by profile (synthetic slate, shake, or tile), brand, and thickness/pattern
  • Tear-off — removing the existing roof down to the deck
  • Synthetic underlay — full-deck polypropylene underlay, plus high-temperature ice-and-water shield at the eaves and valleys in cold climates
  • Hip and ridge cap — matched composite cap per linear foot
  • Metal valley flashing — pre-painted aluminum or copper open valley per linear foot (preferred treatment for composite slate)
  • Pipe and skylight penetrations — per-unit prefabricated flashing kits
  • Permit, disposal, and weekend premium

A $580 minimum service-call floor applies in most US composite markets — even small composite repairs need a manufacturer-certified installer, a courier on the bundle, 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 profile — synthetic slate (most common), shake (cedar look), or tile (Spanish/barrel).
  3. Pick brand — DaVinci (default), EcoStar, Brava, Inspire, F-Wave, or generic value-tier.
  4. Pick thickness/pattern — single-thickness, multi-width staggered (default), or premium thick.
  5. Set scope — spot repair (15% of area), partial replace (45%), or full reroof (100%).
  6. Set storey count — single-storey 1.0x, two-storey 1.2x, three-storey 1.45x.
  7. Set access difficulty — easy (drive-up) is 1.0x, moderate (rear garden) 1.1x, hard (lift required) 1.3x.
  8. Enter hip and ridge cap and metal valley in linear feet, and pipe/skylight penetrations count.
  9. Toggle tear-off, underlay, permit, disposal, and weekend premium, plus any extra labour hours.

Cost drivers

Brand premium. DaVinci sets the ceiling and the standard. EcoStar tracks 8 percent below DaVinci with 80 percent post-industrial recycled content. Brava and Inspire track within 5 percent of EcoStar. F-Wave REVIA undercuts DaVinci by about 22 percent. Generic value-tier polymer can be 30 to 45 percent below DaVinci but typically carries a 30-year warranty instead of 50.

Profile premium. Synthetic slate (the default) is the baseline. Shake profile is about 8 percent cheaper because the masters are less complex. Spanish/barrel tile is 5 percent more expensive because of double-curve moulding tolerances — Brava is the price leader in this profile.

Thickness/pattern. Multi-Width Staggered Slate (the default) gives the most realistic slate look at the baseline price. Single-Width Thick Slate adds 15 to 20 percent for a premium dimensional appearance preferred on heritage and high-end custom homes. Single-thickness uniform is the value option, 10 to 14 percent cheaper.

Hail rating. All major brands carry UL 2218 Class 4 (the highest). In TX, OK, KS, NE, CO, MO, IA, and AR this triggers 15 to 35 percent annual insurance premium discount — typically pays back the premium over architectural asphalt within 8 to 12 years.

Roof complexity. A simple 6/12 to 8/12 gable installs fast. Cut-up roofs with multiple dormers, valleys, hip-and-ridge transitions, and chimneys add 20 to 40 percent vs simple gable because every transition needs metal flashing in linear feet.

US code, standards, and certifications

  • IRC 2024 R905.16 — Synthetic slate and shake provisions (minimum pitch 4/12, double underlay below 4/12, ice-and-water shield in cold climates).
  • UL 790 / ASTM E108 — Fire test of roof coverings (Class A, B, or C). All major composites carry Class A.
  • UL 2218 — Impact resistance test for prepared roof covering materials (Class 1 to Class 4). All major composites carry Class 4.
  • ASTM D3161 — Wind resistance test for roof shingles (Class A, D, F). DaVinci is rated Class F (110 mph).
  • ICC-ES Evaluation Reports — DaVinci ESR-2119, EcoStar ESR-4023, Inspire ESR-1791, F-Wave ESR-4283.
  • ASTM F1667 — Driven fasteners standard (composite uses standard hot-dipped galvanized roofing nails or 1-1/4 in stainless ring-shank).
  • OSHA 29 CFR 1926.501 — Fall protection above 6 ft.

Use a manufacturer-certified installer for any composite project. DaVinci Masterpiece Contractor, EcoStar Premium Contractor, Brava Certified Installer, Inspire Premier Contractor, and F-Wave Authorized Installer are the formal programs — without certification, the 50-year manufacturer warranty can be reduced to 30 years or voided.

Diagnostic step-by-step before quoting

  1. Verify the deck is sound — open soft spots from the attic side. Reroof projects often turn into partial deck-replacement projects ($60 to $90 per 4x8 sheet of OSB or plywood installed).
  2. Check hail history — search your address on hailtrace.com or the NOAA Storm Events Database. Repeat hail history (3+ Class 2+ events in 10 years) makes the Class 4 insurance discount compelling.
  3. Confirm the spec matches the warranty — insist on the manufacturer’s certified installer registration number and the UL 2218 Class 4 / UL 790 Class A certificates with the bundle delivery.
  4. Get three certified-installer bids that itemize composite brand and profile, underlay (synthetic + ice-and-water shield), metal flashings, hip & ridge cap, pipe and skylight penetrations, and permit as separate line items. Lump-sum bids hide cost drivers.
  5. Confirm warranty transfer terms — DaVinci, EcoStar, Inspire, F-Wave, and Brava all transfer to next homeowner; some require a small re-registration fee at year 30. This is a measurable resale-value asset.

Avoiding scams and overcharging

Door-knocker roofers occasionally push composite replacement when only spot repair is needed after a hailstorm — Class 4 composite shingles are designed to survive most hailstorms intact even when adjacent gutters and screens are dented. Red flags include claims that “the entire roof needs replacement” when only the south and west elevations show legitimate strike marks, refusal to identify which composite brand they propose, refusal to commit to the manufacturer’s certified installer program, no proof of $1M+ general liability insurance, and cash-only or wire-transfer demands. Reputable composite roofers in 2026 carry $2M general liability, $1M auto, $500K worker compensation, are certified by at least one major composite manufacturer, and provide the certificate number and a workmanship warranty in writing. Verify certification directly at davinciroofscapes.com, ecostarroofs.com, bravarooftile.com, inspireroofing.com, or fwaverevia.com.

Frequently asked questions

How much does a composite roof cost in 2026 in the US?
Most US homeowners pay $7.50 to $13.50 per sq ft installed for a synthetic slate or shake composite roof in 2026, all-in with tear-off, synthetic underlay, hip and ridge cap, metal valley flashing, pipe and skylight penetrations, and a permit. A 2,000 sq ft single-storey home with DaVinci Bellaforte Slate Multi-Width lands around $22,000 to $30,000. EcoStar Majestic Slate is about 8 percent cheaper; Brava is 10 to 12 percent cheaper; F-Wave REVIA is roughly 22 percent cheaper. Premium thick profiles (DaVinci Single-Width Slate, Inspire Aledora) add 15 to 20 percent. Generic value-tier composite undercuts DaVinci by 30 to 35 percent but typically has a 30-year warranty instead of 50.

DaVinci vs EcoStar vs Brava vs Inspire vs F-Wave — which composite brand is best?
DaVinci Roofscapes (Lenexa, Kansas) is the price-and-quality leader — 50-year material warranty, Class 4 impact, Class A fire, made from 100 percent virgin polymer with the most realistic slate replication. EcoStar (owned by Carlisle SynTec) uses 80 percent post-industrial recycled rubber and plastic with a 50-year warranty and is the leading green-build choice — most LEED projects specify EcoStar. Brava Roof Tile (Iowa) has a lifetime limited warranty, is the lightest composite (140 to 180 lb per square), and pioneered the synthetic Spanish/barrel tile profile. Inspire by Boral (now part of Westlake Royal) competes head-to-head with DaVinci and is preferred by some West Coast architects. F-Wave REVIA is the budget play — 50-year warranty, Class 4 impact, but slightly less dimensional appearance and fewer color options. For most homeowners wanting the closest visual match to natural slate, DaVinci Bellaforte or Multi-Width Slate is the default. For LEED or recycled-content projects, EcoStar. For Spanish tile profile, Brava.
Composite vs real slate vs cedar shake — when does composite make sense?
Composite makes sense when you want the look of slate or cedar shake without the structural and cost burden. Real slate weighs 800 to 1,500 lb per square and typically requires structural framing reinforcement that can add $8,000 to $25,000; composite slate weighs 150 to 250 lb per square — the same as architectural asphalt — and installs on existing framing. Real slate costs $18 to $35 per sq ft installed; composite slate is $7.50 to $13.50. Cedar shake costs $9 to $15 installed but needs treatment in WUI zones and has a 25 to 40-year service life vs composite's 50 years. Composite is also Class 4 impact rated (the highest hail rating, qualifies for 15 to 35 percent insurance discounts in TX, OK, KS, NE, CO, MO) — real slate and cedar are not. The downside: composite is a polymer product, not a natural one — purists notice up close, and resale-value premium in heritage neighborhoods favors real slate.
Is Class 4 impact really worth it and how much will my insurance discount be?
Yes in hail-prone regions. Class 4 impact rating (UL 2218) is the highest hail rating — a 2-inch steel ball dropped from 20 ft does not crack the shingle. All major composite roofing brands carry Class 4. Insurance discounts vary by carrier and state: State Farm and Allstate offer 15 to 28 percent premium discounts in TX, OK, KS, NE, CO, MO, IA, and AR; Travelers and Farmers offer 20 to 35 percent in hail alleys. On a $3,500 annual policy that is $525 to $1,225 per year — composite roofs typically pay back the premium over architectural asphalt within 8 to 12 years through insurance savings alone, before counting the longer service life. Get a written declaration page reference from your agent before signing for composite, and submit the manufacturer's UL 2218 Class 4 certificate and installation invoice to claim the discount.
How long does composite installation take and what is the warranty?
A 2,000 sq ft single-storey full reroof with DaVinci Multi-Width Slate takes 5 to 8 working days with a 3-person crew, weather permitting — about 30 percent faster than real slate (which needs slate hooks and copper nails) and 15 percent faster than cedar (which needs Cedar Breather). The standard manufacturer warranty is 50 years material on DaVinci, EcoStar, Inspire and F-Wave REVIA; Brava has a lifetime limited material warranty. All four major brands transfer the warranty to subsequent homeowners (sometimes with a small re-registration fee at year 30) — this is a measurable resale-value asset. Installer workmanship warranty should be at least 10 years for a certified installer. Insist on the manufacturer's certified installer registration — DaVinci Masterpiece Contractor, EcoStar Premium Contractor, Brava Certified Installer — without it, the manufacturer warranty may be reduced from 50 years to 30 or void entirely.
What is the minimum and maximum roof pitch for composite shingles?
Composite slate and shake require a minimum pitch of 4/12 (about 18 degrees) per IRC R905.16 and manufacturer specs. Below 4/12, water sits in the keyways. Some manufacturers (DaVinci, Brava) approve installation down to 3/12 with double underlay (typically two layers of high-temp ice-and-water shield) and reduced warranty. There is no practical maximum pitch — composite is regularly used on church steeples and Victorian turrets at 18/12 (about 60 degrees). The traditional optimum is 6/12 to 12/12. Composite tile profile (Spanish/barrel) requires 4/12 minimum but installs best at 5/12 or steeper. Cold-climate installs in MN, ND, WI, MI, ME require high-temperature ice-and-water shield to the warm wall, not just 3 ft past the eave.
Does composite need underlayment, ice-and-water shield, and starter strip?
Yes to all three. Synthetic underlay (one layer of 30-pound or upgraded polypropylene like GAF Tiger Paw or Owens Corning Pro Armor) is required on the full deck. High-temperature ice-and-water shield (GAF StormGuard HT, Grace Ice & Water Shield HT, or equivalent) is required at the eave to the warm wall + 24 inches in cold climates (IRC R905.1.2), at all valleys, at penetrations, and at any roof-to-wall transition. Starter strip is a continuous course of matched composite or a metal drip-edge starter at the eave — required for wind warranty. Skipping any of these voids the manufacturer warranty on most brands. Cost is built into the calculator as the underlay line item; metal valley and pipe flashings are separate line items.
What is the difference between Multi-Width, Single-Width, Bellaforte, and Aledora?
These are the major composite slate profiles. DaVinci Multi-Width Slate (default) mimics 5-inch, 7-inch, 9-inch, and 12-inch real slate widths stacked randomly — most realistic. DaVinci Single-Width Slate is uniform 12-inch width, premium thick, 25 percent more expensive. DaVinci Bellaforte Slate is a hybrid panel system (locking) that installs 30 percent faster than Multi-Width with the same visual but slightly less random pattern — popular with installers, growing in spec. EcoStar Majestic Slate, Brava Old World Slate, Inspire Classic Slate, and F-Wave REVIA Slate are competing equivalents to Multi-Width. For shake profile: DaVinci Single-Width Shake, EcoStar Seneca Shake, Brava Cedar Shake, and Inspire Aledora Shake are the equivalents to hand-split cedar.
