Stone coated steel pricing calculator
Split field cartons (squares per bundle + high waste) from hip/ridge accessory counts—how granular tile-look steel kits are actually ordered.
Stone-coated field + hip/ridge
Granular profiles ship as interlocking kits. Field cartons cover a published fraction of a square; hip and ridge pieces scale with lineal feet. Expect higher waste on cut-up plans than plain panels.
Kit-style takeoff
Splits field bundles from hip/ridge pieces—not plain corrugated sheet counts.
How to Calculate Stone Coated Steel Pricing Calculator Manually
Step 1: Pin Down the Verified Roof Area
Never price from house sq ft. Get sloped roof surface from a plane-by-plane takeoff, aerial measurement, or pitch-corrected footprint. Wrong area is the #1 budget error.
Step 2: Choose Unit Rates from Current Quotes
Material cost per square (100 ft²) and labor cost per square change with markets and material types. Asphalt labor often runs $50–$120/sq; premium materials like slate or metal can be $200–$400+/sq installed.
Step 3: Add Accessory and Fixed Line Items
Drip edge, ice & water shield, underlayment, ridge cap, step flashing, and pipe boots are separate costs. A rough allowance is 10–20% on top of field shingles for accessories on a basic gable.
Step 4: Include Tear-Off, Disposal, and Permits
Single-layer shingle tear-off typically runs $1.00–$2.50/ft². Tile or layered tear-offs run $3–$5+/ft². Dumpster rental often adds $300–$600. Building permit fees range $50–$500 depending on jurisdiction.
Step 5: Apply Waste Before Finalizing Bundle Count
Add 5–8% waste for simple gables, 10–15% for cut-up hip or valley roofs, before converting ft² to bundle count. Always round up to whole bundles.
Stone Coated Steel Pricing Calculator Formulas
- Sloped roof area = Plan footprint ft² × Slope factor (e.g. 1.118 for 6/12 pitch)
- Field shingle material = (Sloped ft² × waste factor) ÷ Coverage per bundle × Price per bundle
- Project total = Field material + Accessories + Tear-off labor + Disposal + Permit fees

Stone-Coated Steel: Field Cartons and Hip-Ridge Accessories Must Be Estimated Together
Field bundles are not the whole PO
Most stone-coated systems publish field coverage by fractional squares per carton, while hips and ridges are sold by dedicated accessory pieces. Keeping both quantities visible avoids the common mistake of pricing only field cartons.
Modular metal shingles differ slightly
When a brand is sold as straightforward pieces-per-square without kit-style accessory logic, use the metal shingles estimator for cleaner modular counts.
Do not use corrugated sheet division
Sheet width x length division is for ribbed sheet systems, not interlocking tile-look profiles. Mixing these methods typically undercounts accessory-heavy roofs.
Dollar rollups
After carton and accessory counts are stable, apply supplier pricing and labor assumptions in the metal roof cost calculator to produce a quote-ready rollup.
Frequently Asked Questions — Stone Coated Steel Pricing Calculator
Field waste, squares per bundle, hip/ridge pieces, and kit vs shingle workflows.
How do you estimate stone coated steel roofing?+
Apply a higher field waste % than smooth panels, divide adjusted squares by squares per field bundle, then add hip/ridge pieces from lineal feet × pieces per foot. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site.
Why is waste higher on stone-coated profiles?+
Tile-look layouts and interlocks burn more cuts on hips and valleys—teens to twenties percent is common on complex plans. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
What is squares per bundle on this page?+
Enter how many roofing squares one field carton covers per the brand chart—brands publish fractional squares per bundle. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
How are hip and ridge pieces counted?+
Measure hip plus ridge lineal feet, multiply by accessory pieces per foot from the kit guide, round up. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
Is this the same as metal shingles pieces per square?+
Similar mindset, but stone-coated kits often sell field cartons by fractional squares with separate hip SKUs—use this split model. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
Do I include underlayment in bundles?+
Often sold separately—price rolls on the metal cost scope tool after quantities firm up. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
Can I use corrugated math here?+
No—corrugated uses sheet rectangles; stone-coated uses cartons plus accessory counts. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions. Recheck dimensions, product coverage, and install requirements before purchase.
Where does sloped ft² come from?+
Main roofing calculator or plane takeoffs—tile-look steel still needs true deck area. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
Does color lot matter for counts?+
Not for math, but order enough extras up front so you do not chase lots mid-job. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
Does this satisfy wind warranty nailing?+
No—fastening patterns are in the manual; this page only brackets bundle and accessory counts. For better estimating accuracy, cross-check material pricing, labor rates, and waste contingency with your project notes, then confirm scope validation before final ordering. This keeps your final estimate aligned with real site conditions and reduces costly quantity revisions.
