Westlake Royal roofing is not one product. It is a five-line steep-slope roofing division of Westlake Corporation that sells clay tile (US Tile), concrete tile (Newpoint), stone coated steel (Unified Steel), and polymer composite slate and shake (DaVinci Roofscapes), plus underlayment and accessories. The short verdict: the portfolio is credible and code-heavy, with Class A fire ratings across every line and warranties that run from 50 years to the life of the building, but Westlake does not publish per-square pricing, so real cost depends on which line you pick, your region, and your roof.
This is an independent review built from published manufacturer specifications and aggregated installer sentiment, not from a Roofing Brief lab test. Where we cite a price, it is a 2026 national installed range for that material type, because Westlake Royal itself does not publish list pricing.
Who makes Westlake Royal roofing, and is it the same as Boral?
Westlake Royal roofing is made by Westlake Royal Roofing Solutions, the roofing arm of Westlake Corporation (formerly Westlake Chemical). Westlake acquired Boral Limited’s North American building products businesses for about $2.15 billion, a deal that closed October 1, 2021, then rebranded the group as Westlake Royal Building Products. So yes, the old Boral roofing tiles you may remember are now sold under the Westlake Royal name. The underlying product lines, plants, and profiles largely carried over.
The roofing portfolio spans four material families under one manufacturer. US Tile clay and Newpoint concrete are the legacy tile lines. Unified Steel is the stone coated steel system. DaVinci Roofscapes is the polymer composite brand, sold both under DaVinci and inside the Westlake Royal catalog.
Westlake Royal roofing lines compared: specs, warranty, and cost
Across the four Westlake Royal roofing lines, every product carries a Class A fire rating and a warranty of at least 50 years, but weight, impact resistance, and installed cost vary widely. Clay and concrete tile are the heaviest and most wind-proven. Unified Steel is the lightest and the only line carrying a Very Severe Hail rating. DaVinci composite splits the difference on weight while mimicking natural slate and shake.
| Line | Material | Key profiles | Approx. weight | Fire / wind / hail | Warranty (published) | Typical installed cost, material type |
|---|---|---|---|---|---|---|
| US Tile | Clay tile | 1-Piece “S”, 2-Piece Mission, ClayLite | 850 to 1,200 lb/square | Class A fire | 50-year limited | $11 to $22 per sq ft |
| Newpoint | Concrete tile | Cedarlite 600, Saxony 900 Hartford Slate | 850 to 1,200 lb/square | Class A fire, Category 5 wind rated | Limited, to the life of the building | $7 to $19 per sq ft |
| Unified Steel | Stone coated steel | Granite-Ridge Shingle, Pacific Tile | about 150 lb/square (1.5 lb/sq ft) | Class A fire, 120 mph wind, Class 4 hail, VSH rated | 50-year limited, fully transferable | Tracks stone coated steel market |
| DaVinci Roofscapes | Polymer composite | Multi-Width Slate, Multi-Width Shake | about 225 lb/square | Class A fire (with underlayment), Class 4 impact | Lifetime limited (residential); 50-year commercial; 10-year non-prorated material and labor | $17 to $30 per sq ft |
Cost columns are 2026 national installed ranges for the material category (concrete tile per HomeGuide, clay per Modernize, composite slate per RoofingCalc and Fixr), not Westlake Royal list prices. A square equals 100 square feet. Heavy tile lines can require a structural check before install, which adds cost some homes cannot avoid.
US Tile clay roofing
US Tile is Westlake Royal’s clay line and one of the few clay tiles still fired in the United States, at the Rialto, California plant. It comes in one-piece “S” tile, two-piece Mission cap-and-pan, and the lighter ClayLite profile, all Class A fire rated. Clay holds color through the body of the tile rather than a surface coat, so it fades slowly and can last 50 years or more. Westlake markets meaningful recycled raw content and Cradle to Cradle certification on the clay range.
Best for: Spanish, Mediterranean, and Southwest homes where authentic fired-clay color and a 50-year horizon justify the weight and the higher installed cost.
Newpoint concrete roof tile
Newpoint is the concrete tile line, engineered for high-wind coastal markets and rated to withstand Category 5 hurricane-force winds when installed to spec. Flagship profiles include Cedarlite 600, a shake look, and Saxony 900 Hartford Slate, a slate look. Concrete tile gives you the tile silhouette and thermal mass of clay at a lower material price, and Westlake warrants the tile against manufacturing defects for the life of the building, a stronger term than the 50-year clay warranty.
Best for: Florida and Gulf Coast homes, and any buyer who wants a tile roof and hurricane-grade wind performance without paying clay prices.
Unified Steel stone coated roofing
Unified Steel is Westlake Royal’s stone coated steel system and the lightest line in the portfolio at roughly 1.5 pounds per square foot, about one-eighth the weight of tile. It is the first stone coated steel roof in the US to earn a Very Severe Hail (VSH) rating, and it carries a Class 4 hail rating and a 120 mph wind rating across five profiles. The warranty is a 50-year limited, fully transferable product warranty, which helps at resale.
Best for: re-roofs over framing that cannot carry tile, hail-belt states, and owners who want the tile or shake look at a fraction of the structural load. For the wider category, see our stone coated steel roofing guide.
DaVinci Roofscapes composite
DaVinci Roofscapes is the polymer composite line, molded from virgin resin to copy natural slate and cedar shake in Multi-Width Slate and Multi-Width Shake profiles. It carries a Class 4 impact rating and, with the correct underlayment, a Class A fire rating, at roughly 225 pounds per square, far below real slate. The warranty is among the strongest in the catalog: a lifetime limited materials warranty on residences, 50 years on commercial, with a 10-year non-prorated material and labor period.
Best for: buyers who want the look of slate or shake without the weight or the maintenance. We break the brand down in depth in our DaVinci Roofscapes review, and compare the category in our composite roofing guide.
Westlake Royal roofing components
Beyond the finished roofs, Westlake Royal sells a components line: synthetic underlayment (marketed as SwiftGuard), battens, ventilation, and flashing accessories meant to be installed with any of its steep-slope systems. These parts matter for warranty compliance, because tile and composite warranties generally assume manufacturer-approved underlayment and fastening. Treat the components as part of the system quote, not an afterthought.
Which Westlake Royal roof is best for you?
The right Westlake Royal line depends on your climate, your framing, and your budget, not on brand loyalty, since all four share the same manufacturer and Class A fire rating. Use this quick guide:
- Hurricane coast, want tile: Newpoint concrete tile, rated to Category 5 wind, with a life-of-building tile warranty.
- Authentic fired-clay look: US Tile, US-made clay with a 50-year warranty.
- Hail country or weak framing: Unified Steel, the lightest line and the only one with a VSH rating.
- Slate or shake look, no weight penalty: DaVinci composite, with a lifetime limited residential warranty.
- Lowest tile entry price: Newpoint concrete generally undercuts clay per square foot.
Pros and cons of Westlake Royal roofing
Westlake Royal’s main strength is breadth: four durable material families under one warranty administrator, all Class A fire rated, covering most steep-slope aesthetics. The main friction is pricing opacity and the structural demands of the tile lines.
Pros:
- Four material families (clay, concrete, stone coated steel, composite) from one manufacturer.
- Class A fire on every line; Category 5 wind on Newpoint; VSH and Class 4 hail on Unified Steel.
- Warranties from 50 years to life-of-building, and Unified Steel’s is fully transferable.
- US-made clay (Rialto, CA) and recycled content plus Cradle to Cradle certification on clay.
Cons:
- No published per-square pricing, so you must get a local quote to know real cost.
- Clay and concrete tile weigh 850 to 1,200 pounds per square and can require a structural evaluation.
- Individual tiles can crack under severe hail and need piece-by-piece replacement.
- Warranty terms are prorated or conditional in parts; read the coverage schedule, not just the headline year.
Westlake Royal roofing vs rivals
Against single-material specialists, Westlake Royal competes on breadth rather than on any one category crown. Eagle Roofing and Boral’s former peers dominate concrete tile; Ludowici and Santafe hold the high end of clay; Brava and Inspire chase DaVinci in composite; DECRA is the best-known stone coated steel name.
| Need | Westlake Royal line | Common alternative |
|---|---|---|
| Concrete tile | Newpoint | Eagle Roofing Products |
| Clay tile | US Tile | Ludowici, Santafe |
| Composite slate/shake | DaVinci Roofscapes | Brava, Inspire (see our composite roofing guide) |
| Stone coated steel | Unified Steel | DECRA |
The practical edge of buying inside one Westlake Royal portfolio is a single warranty administrator and one components ecosystem across whichever look you choose. To compare warranty language line by line against other brands, see our roofing warranty comparison database.
How we assessed Westlake Royal roofing
This review aggregates published Westlake Royal and DaVinci product specifications, the 2021 Boral acquisition record, and 2026 national installed-cost ranges by material type from HomeGuide, Modernize, RoofingCalc, and Fixr. We did not physically test these roofs. Figures are current as of publication and may change; verify warranty coverage and pricing with an authorized Westlake Royal contractor before you buy. Cost varies by region, roof pitch, tear-off, and framing.
Frequently asked questions
Is Westlake Royal roofing the same as Boral?
Effectively yes. Westlake Corporation bought Boral Limited’s North American building products businesses for about $2.15 billion in a deal that closed October 1, 2021, then rebranded them as Westlake Royal Building Products. The former Boral concrete and clay roofing tiles, along with US Tile, Newpoint, Unified Steel, and DaVinci, now sell under the Westlake Royal name, with the same underlying profiles and plants.
How much does a Westlake Royal roof cost?
Westlake Royal does not publish per-square pricing, so cost depends on the line and your region. As 2026 national installed ranges by material type, concrete tile runs about $7 to $19 per square foot, clay tile about $11 to $22, and composite slate about $17 to $30. Heavy tile may add a structural evaluation. Always get a local quote from an authorized contractor.
What warranty comes with Westlake Royal roofing?
It varies by line. Newpoint concrete tile is warranted against manufacturing defects for the life of the building. US Tile clay carries a 50-year limited warranty. Unified Steel stone coated steel has a 50-year limited, fully transferable warranty. DaVinci composite carries a lifetime limited materials warranty on homes, 50 years commercial, with a 10-year non-prorated material and labor window. Read the coverage schedule, since parts are prorated.
Is Westlake Royal roofing any good?
By published specs, it is a credible, code-heavy portfolio. Every line is Class A fire rated, Newpoint is rated to Category 5 winds, and Unified Steel is the first US stone coated steel with a Very Severe Hail rating. The main drawbacks are pricing opacity and the weight of the tile lines, which can require structural reinforcement on some homes.
Is DaVinci part of Westlake Royal?
Yes. DaVinci Roofscapes is the polymer composite brand within Westlake Royal Roofing Solutions, sold both under the DaVinci name and inside the Westlake Royal catalog. It makes Multi-Width Slate and Multi-Width Shake composite tiles with a Class 4 impact rating and a lifetime limited residential materials warranty, weighing roughly 225 pounds per square, far less than natural slate.
How long does a Westlake Royal tile roof last?
Clay and concrete tile from Westlake Royal are engineered for 50-year-plus service lives, and the tile bodies themselves often outlast that. The Newpoint concrete warranty runs to the life of the building against manufacturing defects, and US Tile clay carries a 50-year limited warranty. Underlayment and flashing usually wear out first, which is why matching Westlake Royal components matter for the full service life.
