Frequently Asked Questions

Everything you need to know about embedding the calculator.

Is this really free? Are there any hidden costs?
Yes — completely free, forever. There are no subscription fees, no watermarks, no usage limits, and no hidden costs. We provide this tool free to roofing companies and home improvement websites as a community resource.
Will the calculator slow down my website?
No. The widget uses lazy loading and loads asynchronously, so it does not block your page from rendering. The script is lightweight (<5KB) and the iframe only loads when it enters the viewport.
Can I customize the colors to match my brand?
Yes. Use the data-color attribute on the widget div to set any hex color as the accent. For example: <div id="rrc-widget" data-color="#ff6b35"></div>.
Does the widget work on WordPress, Wix, and Squarespace?
Yes. The JavaScript embed works on WordPress (Gutenberg HTML block, Elementor HTML widget, Divi Code Module), Wix (Custom HTML element), Squarespace (Code Block), Webflow (Embed element), and any custom HTML site.
How accurate are the cost estimates?
The calculator uses 2025–2026 contractor pricing data aggregated from across the US, adjusted by region, material type, roof pitch, and complexity. Estimates are accurate within ±15–20% of actual contractor quotes, which is typical for pre-quote estimating tools.
Do I need to attribute or link back to your site?
The widget automatically includes a small "Free tool by ReplacementRoofCalculator.com" attribution link below the calculator. This is required as part of the free license. It's small, tasteful, and actually helps your visitors — they can visit our site for more detailed state and city breakdowns.
