DaVinci Single-Width Shake delivers a Class A fire rating — the only synthetic shake at 9-inch single width that hits this mark while maintaining authentic cedar appearance. Contractors get Class 4 impact rating (UL 2218) and 110 MPH wind resistance certified, solving Montana’s hail and chinook wind challenges without sacrificing the hand-split look clients want.
The product uses engineered composite polymer made of virgin resins with UV/thermal stabilizers and fire-retardant additives. This composition delivers a 50+ year lifespan compared to 15-30 years for real wood. At approximately 3 lbs per square foot, it’s light enough for efficient installation but substantial enough to handle mountain weather.
Fire and Impact Performance
The certifications matter. Class A Fire Rating (ASTM E108) means these shakes won’t fuel a wildfire — critical when 37% of Flathead County sits in WUI zones. Natural wood typically rates Class C unless treated, and those treatments don’t last. Class 4 Impact Rating (UL 2218) handles Montana’s summer hail without the dents and cracks that plague lesser products.
Wind certification up to 110 MPH exceeds what most valleys need but provides margin for exposed ridgelines and chinook corridors. For the Class A fire rating, requires Class A fire-rated underlayment — not negotiable if you want the full protection.
| Certification | Rating | Standard |
|---|---|---|
| Fire Resistance | Class A | ASTM E108 |
| Impact Resistance | Class 4 | UL 2218 |
| Wind Resistance | 110 MPH | (certified) |
| Lifespan | 50+ years | (manufacturer) |
Additional certifications include CA Title 24 (Cool Roof colors), Miami-Dade County Acceptance (NOA), and Texas Department of Insurance (TDI) — overkill for Montana but shows the product’s been torture-tested in multiple climates.
Installation Specifications
Single-width design at 9 inches wide simplifies layout compared to multi-width systems. Tiles run approximately 22 inches long with 5/8-inch thickness. Exposure options at 9-inch or 10-inch let contractors adjust coverage and appearance. Tiles lay in straight or staggered courses — staggered gives more natural variation.
Minimum slope requirement is 4:12. Anything flatter won’t shed Montana snow loads properly. Stainless steel or copper nails are recommended for optimal longevity — don’t cheap out on fasteners when the product’s engineered to last 50 years. Compatible with copper, stainless steel, and galvanized flashing.
| Specification | Value |
|---|---|
| Tile Width | 9 inches |
| Tile Length | ~22 inches |
| Thickness | 5/8 inches |
| Exposure Options | 9 or 10 inches |
| Minimum Slope | 4:12 |
| Weight | ~3 lbs/sq ft |
Works with standard synthetic or felt underlayments, though premium options required for full fire rating. Packaging comes bundled with typically 22 tiles per bundle.
Material Composition and Durability
Virgin resins with UV/thermal stabilizers and fire-retardant additives create the performance difference. Virgin material matters — recycled content can’t match the consistency and longevity. The product resists fading, rot, mold, and mildew, solving the maintenance headaches that plague natural cedar in Montana’s wet-dry cycles.
Deep grooves and authentic grain patterns mimic natural hand-split cedar. Randomized mold texturing and pigmentation deliver a highly realistic appearance. The single-width format might seem limiting, but provides a more uniform, consistent look versus multi-width options that offer a more varied, rustic appearance.
The material’s suited for all climates but especially high-humidity, high-wind, and fire-prone regions. Montana hits all three criteria. Lifetime Limited Material Warranty with 10-year non-prorated period for manufacturing defects backs the durability claims.
Accessories include starter tiles, two-piece hip & ridge caps, 6-inch hip & ridge tiles, valley flashing, and solid tiles for custom cuts — everything needed for a complete installation without mixing product lines.
FAQ
How does DaVinci Single-Width compare to Bellaforte shake?
Bellaforté is more cost-effective and easier to install due to its 12-inch width and interlocking system. DaVinci Single-Width focuses on authentic appearance and maximum fire/impact ratings rather than installation speed.
What makes this product worth the premium over standard architectural shingles?
Class A fire rating versus typical Class C for natural wood, plus Class 4 impact resistance that architectural shingles can’t match. 50+ year lifespan compared to 15-30 for cedar changes the math on lifecycle cost.
Does the single-width design limit aesthetic options?
Single-width provides a more uniform, consistent look while multi-width creates a more varied, rustic appearance. Straight or staggered coursing options add variation within the single-width format.
What’s required for the Class A fire rating?
Class A fire-rated underlayment is mandatory for the Class A rating. Standard underlayment drops the assembly’s fire resistance.
How does installation differ from natural cedar shake?
Same basic process but stainless steel or copper nails recommended instead of standard roofing nails. 4:12 minimum slope requirement matches cedar. At 3 lbs per square foot, it’s lighter than cedar, making handling easier.
