## Description

Estimate sloped roof area from supplied plan dimensions and pitch. Add a separate
row for each rectangular section.

Add the SlopeQuill Roof Area Estimator block or [roof_area_estimator] shortcode.
Labelled keyboard controls, isolated repeat instances and a responsive layout inherit
your site’s font and text colour. Download a plain-text summary or use Print summary.
No account, API, analytics, cookies, lead capture or visitor-data storage. All inputs
stay in the current page until you download them. The tool sends nothing to a provider.

Plan area is length × width. Sloped area is plan area ÷ cos(pitch). The allowance
is applied once to the total sloped area. This rectangular approximation excludes
complex shapes, overlaps, ridges and penetrations; it is not a material order, quote
or structural assessment. Use dimensions and pitch from existing plans or a professional;
no access to a roof is needed to use this tool.

Site-wide settings:
 * Default area allowance (%): 10.

All functionality works without attribution.
