DaVinci Single-Width Shake delivers Class A fire rating (ASTM E108) and Class 4 impact rating (UL 2218) — critical specs for Montana’s wildfire zones and hail-prone regions. Each 9-inch wide tile runs approximately 22 inches long with 5/8-inch thickness, creating the uniform appearance many architects prefer over multi-width options.
The tiles carry 110 MPH wind resistance certification, suitable for Montana’s chinook wind events. At approximately 3 pounds per square foot, they’re light enough for standard roof structures while heavy enough to resist uplift.
Performance Specifications That Matter
The performance numbers separate DaVinci from traditional cedar shake. Natural wood typically rates Class C for fire resistance unless chemically treated. DaVinci’s Class A rating means embers won’t ignite the roof — no chemical treatments needed, no reapplication required.
The composite material consists of pure virgin resins, UV and thermal stabilizers, and specialized fire retardants. This isn’t recycled plastic masquerading as roofing. The virgin resin construction resists fading, rotting, cracking, and pest damage.
| Specification | Value | Source |
|---|---|---|
| Fire Rating | Class A (ASTM E108) | Tested |
| Impact Rating | Class 4 (UL 2218) | Tested |
| Wind Rating | 110 MPH | Certified |
| Tile Width | 9 inches | Manufacturer |
| Tile Length | ~22 inches | Manufacturer |
| Thickness | 5/8 inches | Manufacturer |
| Weight | ~3 lbs/sq ft | Manufacturer |
| Warranty | Lifetime Limited | Manufacturer |
The warranty includes a 10-year non-prorated period for manufacturing defects. After that, coverage continues but with prorated replacement costs.
Installation and Exposure Options
Contractors can install at either 9-inch or 10-inch exposure, depending on the look they’re after. The 9-inch exposure creates tighter coursing for a more refined appearance. The 10-inch stretches coverage slightly while maintaining weather protection.
Minimum roof slope sits at 4:12 — standard for most residential applications. Tiles lay in either straight or staggered courses. Straight coursing delivers clean horizontal lines. Staggered creates more visual texture without the randomness of multi-width products.
Each bundle contains 22 tiles, simplifying job site math. DaVinci recommends stainless steel or copper nails for optimal longevity — galvanized fasteners work but won’t match the roof’s lifespan.
The Class A fire rating requires Class A fire-rated underlayment. Standard synthetic underlayment drops the assembly to Class B or C. In Montana’s wildfire zones, that distinction matters for insurance and code compliance.
Comparison to Other DaVinci Shake Lines
Single-Width provides a uniform, consistent look while Multi-Width delivers a varied, rustic appearance with multiple tile widths. The Single-Width’s 9-inch consistency appeals to contemporary designs where clean lines matter. Multi-Width suits traditional styles seeking that hand-split randomness.
Bellaforté proves more cost-effective and easier to install due to its 12-inch width and interlocking system. Wider tiles mean fewer pieces per square, cutting installation time. The interlocking design eliminates some of the alignment challenges inherent in individual shake installation.
Single-Width targets sleek, modern aesthetics with its uniform 9-inch width ensuring a refined appearance suitable for contemporary or transitional homes, while featuring randomized mold texturing and pigmentation for a realistic hand-split cedar look.
For Montana contractors, the choice often comes down to fire rating needs and installation speed. All three lines deliver the Class A fire protection. Installation efficiency varies significantly — Bellaforté’s 12-inch interlocking system installs fastest, Multi-Width takes longest with its varied sizing, and Single-Width falls in the middle.
The real advantage shows in Montana’s short construction season. Every day saved on roofing means another project completed before October snow flies. Single-Width balances authentic appearance with reasonable installation time — neither the fastest nor the slowest option, but delivering consistent results.
