IMPORTANT ESTIMATING DISCLAIMER
This calculator provides preliminary planning estimates only. Results are based on user-entered measurements and selected assumptions; they are not a quote, guaranteed material list, installation plan, or recommendation that a product is suitable for your roof. Actual quantities and costs may vary with roof geometry, pitch, overlaps, cuts, waste, product coverage, installation requirements and site conditions. Metal panel estimates assume rectangular roof planes and continuous panels without end laps; complex roofs require a detailed takeoff.

Unless expressly included in the results, estimates exclude accessories, underlayment, flashing, trim, fasteners, ventilation, tear-off, disposal, decking or structural repairs, delivery and taxes. Any entered pricing is a user-supplied allowance, not a Home Lumber price or offer.

Before purchasing, cutting or installing materials, have a qualified roofing professional verify all measurements, quantities, panel lengths, product suitability, manufacturer instructions and applicable code requirements. This tool does not evaluate structural capacity or roof condition. Home Lumber & Supply does not guarantee the accuracy or completeness of calculator results. Final quantities, availability and pricing must be confirmed with your Home Lumber store. Do not order materials solely from this estimate.
