Editorial Policy

Editorial Standards

RoofingCalculatorUSA publishes independent, research-driven roofing content. Calculators, reports, and statistics are built to be transparent, reproducible, and educational. We disclose commercial relationships that could influence editorial decisions.

Fact Checking

Every published number is traced to a source — government data, industry reports, manufacturer pricing, or contractor/homeowner surveys. Numbers are reviewed on every publication and re-validated during periodic refresh cycles.

Source Verification

We prioritize primary sources (government, manufacturer, public filings) over secondary aggregators. All sources we routinely cite are listed in our Sources Library.

Content Updates

Cost data, statistics, and reports are reviewed at least quarterly. Pages reflecting time-sensitive data display a "last updated" date. Material changes to pricing or claim trends are documented when published.

Corrections Policy

If we identify or are notified of a factual error, we correct the page promptly and note the correction. To request a correction, contact our editorial team via the contact page.

Research Process

Our research process follows four steps: (1) define the question, (2) collect data from primary sources, (3) cross-check against secondary references, (4) publish with methodology and source attribution. Internal review precedes every publication.
