DaVinci Roofscapes manufactures polymer slate and shake roofing systems that look like natural materials but perform better in harsh weather. They’re not trying to be the cheapest synthetic option. They build high-performance composite roofing and siding as maintenance-free alternatives to natural slate and cedar.
Worth it for contractors dealing with wildfire zones, heavy snow loads, or customers who want the slate look without the weight. Skip it if you’re competing on price alone — their products run 20-30% less than natural slate or cedar, but they’re still premium-priced compared to asphalt.
Multi-Width Slate: The Workhorse for Variable Patterns
DaVinci’s Multi-Width Slate comes in five widths (6”, 7”, 9”, 10”, 12”) with a consistent 1/2” butt thickness. That variety matters when you’re trying to avoid the cookie-cutter look of uniform synthetic tiles. Mix the widths randomly and you get something that passes for real slate from the street.
The weight varies with exposure:
| Specification | Value |
|---|---|
| Weight at 8” exposure | 266 lbs/square |
| Weight at 7.5” exposure | 283 lbs/square |
| Weight at 7” exposure | 304 lbs/square |
| Weight at 6” exposure | 354 lbs/square |
That’s heavy for synthetic but still lighter than real slate. More importantly for Montana conditions:
| Performance Rating | Value |
|---|---|
| Fire test (ASTM E 108) | Class A |
| Impact test (UL 2218) | Class 4 |
| Wind test (ASTM D 3161) | Certified to 110 mph |
| High velocity hurricane zone (TAS 125) | Up to 180 mph |
Class 4 impact rating means it’ll handle hail that would crack real slate. Class A fire rating meets wildfire zone requirements. And 110-180 mph wind ratings cover anything Montana can throw at it, including those mountain ridge exposures.
Select Shake: When Cedar Look Matters More Than Cedar Problems
Select Shake comes in 8” and 10” widths, both 22” long, with 5/8” butt thickness tapering to 1/4” at the top. The 10” pieces have a simulated keyway that makes them look like 4” and 6” pieces — smart way to get multi-width appearance without sorting multiple sizes.
Weight runs approximately 2.8 lbs per square foot, which translates to:
| Specification | Value |
|---|---|
| Weight at 10” exposure | 300 lbs/square |
| Weight at 9” exposure | 333 lbs/square |
Performance matches the Multi-Width Slate:
| Performance Rating | Value |
|---|---|
| Fire rating | Class A |
| Impact rating | Class 4 |
| Wind resistance | Certified up to 110 mph |
| Hail resistance | Resistant to 90 mph simulated hail |
Minimum pitch is 15 degrees (3:12), maximum 70 degrees. Installation temperature flexibility is a Montana advantage — can be installed below 45°F, though they recommend warmer storage.
Authentic wood-profile molds taken from actual cedar shakes give realistic texture. Unlike real cedar that’ll split, cup, and feed the woodpeckers after a few freeze-thaw cycles, this resists water absorption, splitting, warping, rotting, and pests.
Hip & Ridge: Complete System Thinking
DaVinci offers both one-piece and two-piece hip and ridge options. The dimensions vary by product:
Two-Piece System:
| Specification | Value |
|---|---|
| Dimensions | 7” x 18” |
| Linear coverage per bundle | 5 linear feet (at 6” exposure) |
| Bundle quantity | 20 pieces |
One-Piece System:
| Specification | Value |
|---|---|
| Slate width | 12” |
| Linear coverage per bundle | 10 linear feet |
| Pieces per bundle | 10 |
Hip starter pieces cover 3/4” to 2” of the first hip tile, available in both 7” and 12” widths — details that separate a professional installation from amateur hour. All mechanically fixed with pre-drilled nail holes, so no guessing about fastener placement.
Montana Climate Performance: Built for the Worst
The composite blend uses virgin resins (polyethylene), UV and thermal stabilizers, and specialized fire retardant additives. That’s not marketing fluff — it translates to real performance advantages in Montana conditions:
Freeze-Thaw Resistance: The engineered composite polymer handles all climates, especially high-humidity and high-wind regions. Unlike clay or concrete tiles that crack when water freezes in their pores, or cedar that splits along the grain, these polymers flex without failing.
Fire Performance: Class A fire rating isn’t negotiable in Montana’s WUI zones. Cedar shakes might look nice, but they’re kindling in a wildfire. DaVinci’s fire retardants are mixed throughout the material, not just surface-applied.
Wind Ratings: 110 mph standard certification, up to 180 mph for high-velocity zones. That covers everything from valley installations to exposed mountain ridges where chinook winds rip standard shingles apart.
Low Temperature Installation: Can be installed below 45°F — crucial when your building season runs May through October and September mornings already drop below that threshold.
Weight Advantage: At 266-367 lbs/square depending on product and exposure, it’s heavy compared to asphalt but light compared to real slate (800-1500 lbs/square). That matters on older structures or long-span trusses designed for lighter loads.
The Professional Verdict
Professional contractors view DaVinci as high-quality, durable, and aesthetically appealing, with realistic appearance that mimics natural materials, Class 4 impact rating, Class A fire rating, and wind resistance up to 110 mph. Contractors appreciate the lightweight design that reduces structural stress and simplifies installation.
The higher initial cost compared to natural wood is the main drawback, but contractors appreciate the long-lasting performance and low maintenance compared to traditional cedar. For projects where authentic aesthetics with enhanced durability matter, especially in areas prone to impact, fire, or high winds, DaVinci delivers.
Products come with a Lifetime Limited Material Warranty. That’s manufacturer confidence, not contractor liability. When you’re selling a roof that costs more upfront, that warranty helps close the deal.
Frequently Asked Questions
Q: How much heavier is DaVinci than standard architectural shingles?
DaVinci products weigh 266-367 lbs/square depending on the specific product and exposure. That’s roughly double the weight of architectural shingles (200-250 lbs/square) but still far lighter than natural slate.
Q: Can DaVinci products handle Montana’s temperature swings?
Yes — they can be installed at temperatures below 45°F, and the composite blend includes thermal stabilizers specifically to handle temperature extremes. The material resists splitting, warping, and degradation from freeze-thaw cycles.
Q: What’s the real advantage over cedar shake in fire zones?
DaVinci has a Class A fire rating compared to cedar’s Class B or C (often untreated). Fire retardant additives are mixed throughout the material, not just surface-applied, so the protection doesn’t wear off.
Q: Do these products require special installation techniques?
Products come with pre-drilled nail holes and pre-sorted, factory-collated bundles for faster installation. Minimum roof pitch is 15 degrees (3:12). Standard roofing practices apply, but the consistent dimensions and pre-sorting actually make installation faster than natural materials.
