Shingle Exposure

Shingle Exposure is an offline-first roof shingle course-layout card for roofers, crew leads, and serious DIY re-roofers. You work one named roof plane at a time—not a generic notes app, material catalog, or multi-job dashboard.

Cold start opens a fullscreen chalk-line surface: rafter run length, shingle exposure, starter course, field courses, and ridge course locked in one glanceable layout. Typed inputs drive live course count, leftover inches, and bundle estimates while the plane is still on the deck.

Snap every chalk line with certainty—one plane, one exposure, exact course rows and bundles without climbing down for a calculator.

WHAT YOU GET
• Fullscreen course-rows chalk-line card for the active named roof plane with oversized rafter-run and exposure fields
• Live course grid that stacks starter, numbered field courses, and ridge as discrete rows, with remaining inches on the last full course
• Exposure presets (standard 5", 5.5", 6" and metric equivalents) plus custom typed exposure in inches or millimeters
• Starter and ridge course toggles with dedicated row height and mark notes for drip-edge and ridge-cap lines
• Bundle estimator from plane area, waste factor, and courses needed—shows whole bundles and leftover shingles
• Named plane library with local persistence: eave length, pitch label, run length, exposure, waste %, and last-edited stamp
• Per-course chalk notes (valley cut, vent chase, step-flashing stop) stored on each row without leaving the card
• Quick-switch between saved planes on the same job; duplicate a plane for the opposite hip or gable mirror
• Read-only layout summary sheet for crew handoff: course count, starter/ridge flags, bundles, and waste—exportable as plain text share
• Settings for unit display (in/mm), default waste percent, and default exposure—fully offline

Built for the deck: open the plane, set exposure, read the rows, mark the lines, estimate bundles, and hand off the summary without leaving the job.
