Roof Repair & Replacement Calculator
Give your roofing company website a competitive advantage with an interactive cost calculator. This template helps homeowners estimate costs for roof repairs, partial replacements, overlays, or full tear-off and replacement. Factors include roofing material (asphalt, metal, tile, slate), roof pitch, number of stories, current condition, and additional work like gutter replacement or skylight repair. Visitors who see transparent pricing are more likely to request an inspection - capture their details and convert browsers into booked jobs.

Frequently Asked Questions
Can I customize the pricing for my local market?
Absolutely. All material costs, labor rates, pitch multipliers, and add-on pricing are fully customizable. You can adjust everything to match your actual costs and profit margins.
Does this work for both repair and replacement estimates?
Yes. The calculator supports multiple service types including simple repairs, partial replacements, overlays, and full tear-off replacements. Each has different pricing multipliers you can customize.
Can I add my own roofing materials?
Yes. You can add or remove roofing material options, add specialty materials like synthetic slate or architectural shingles, and set custom pricing for each.
How does this help generate roofing leads?
Homeowners researching roof costs are high-intent leads. The calculator engages them with instant estimates, and the submit button collects their contact information for follow-up inspections. Studies show interactive tools increase conversion rates by 2-3x.
Can I capture customer information for follow-up?
Yes. The submit button can be configured to collect name, email, phone, and address before showing the final estimate. You can also connect it to your CRM via webhooks.
