DaVinci Province Slate delivers composite polymer roofing tiles with Class 4 impact and Class A fire ratings in a self-aligning design that installs faster than natural slate. The 12” x 11.5” single-width tiles create an 8” exposure and handle Montana’s freeze-thaw cycles through virgin resin construction with UV and thermal stabilizers. For contractors facing short building seasons and extreme weather, Province Slate offers durability certifications that matter while cutting installation time compared to traditional slate.
Performance Ratings and Material Specifications
Province Slate earns Class A fire rating (ASTM E108) and Class 4 impact rating (UL 2218), plus hurricane wind performance rating for high-velocity zones. The composite polymer construction uses virgin resins, UV and thermal stabilizers, and fire retardant throughout. That’s the engineering that survives Montana’s temperature swings and hailstorms.
Each tile measures 12 inches wide by 11.5 inches long, creating an 8-inch exposure. The butt thickness of 5/8 inch tapers to 3/8 inch at the tip. Installation requires a minimum 3:12 pitch with APA-approved plywood (at least 15/32”) or OSB (at least 7/16”).

Cool Roof options meet California Title 24 compliance for energy efficiency. The material resists mold, algae, fire, pests, and salt air – won’t curl, cup, or split like natural materials. Manufacturing happens in Lenexa, Kansas.
Installation Efficiency and Requirements
The self-aligning ledge on tile backs speeds placement, maintaining the required 3-inch side-lap. Standard installation uses 2 nails per tile, increasing to 4 nails in high-wind areas. Fasteners must be hot-dip galvanized, copper, or stainless steel roofing nails that penetrate the deck by at least 3/16 inch.
Pitch between 3:12 and 4:12 requires full self-adhered membrane underlayment. Above 4:12 pitch, standard approved underlayment works. Starter tiles need 3/8” to 1/2” spacing for thermal movement. Pre-collated bundles come sorted by color for authentic blending.
The system includes field tiles, starter tiles, one-piece hip and ridge tiles in multiple pitches, rake tiles for gable ends, and transition tiles for flashings and valleys. This complete accessory lineup eliminates jobsite fabrication.
Some contractors note the material’s surface can be scratched with a fingernail, raising concerns about surface hardness during installation. Handle with care during placement. The color-through technology means color penetrates the entire tile – minor surface marks won’t expose different-colored substrate.
Weight Considerations and Structural Planning
Province Slate weighs less than natural slate but potentially more than standard asphalt shingles – structural review advised for older buildings. The spec sheet doesn’t provide exact psf loading, so contractors need to verify existing roof structure capacity before bidding retrofits.
The product handles freeze-thaw conditions and salt-air environments. It’s 100% recyclable virgin resin construction. An optional ‘Renaissance’ finish adds Kynar UV protection for projects demanding maximum fade resistance.
Province Slate suits contractors who need proven impact and fire ratings without natural slate’s weight and fragility. The self-aligning installation saves labor hours during Montana’s compressed building season. Just verify the structure can handle the load – this isn’t a direct shingle swap.
Frequently Asked Questions
Q: What warranty coverage comes with DaVinci Province Slate?
Province Slate includes a Lifetime Limited Material Warranty with 10-year non-prorated coverage against manufacturing defects that includes both material and labor. The warranty is transferable subject to manufacturer terms.
Q: Can Province Slate handle Montana’s temperature extremes?
The composite polymer includes thermal stabilizers specifically for temperature resistance. The material is engineered for freeze-thaw resistance and performs in all climates, including extreme cold. The Class 4 impact rating handles hailstorms that destroy standard shingles.
Q: How does Province Slate compare to natural slate for installation time?
The single-width, self-aligning tiles with the ledge on back facilitate rapid and consistent installation. The cost-effective design allows faster installation, reducing labor costs. Contractors report significant time savings versus sizing and placing natural slate pieces.
Q: What roof pitches work with Province Slate?
Province Slate requires minimum 3:12 pitch. Roofs from 3:12 to 4:12 need full self-adhered membrane underlayment, while pitches above 4:12 use standard approved underlayment. The system works on gable, hip, valley, and transition roofs.
Q: Does the surface scratch easily during installation?
Yes, contractors report the material’s surface can be scratched with a fingernail. Careful handling during installation prevents surface damage. The color-through technology means scratches won’t expose different-colored material underneath.
