Roofing QC App Development

I want a simple, field-friendly mobile app that lets our roof-tile installers record every aspect of a job and automatically email the finished report—complete with photos—to our office the moment they hit “submit.” The form shown here is the exact workflow I need replicated and refined:

Key functions I need built in:

• Runs smoothly on both Android and iOS so every crew member’s phone or tablet is covered.

• Captures the full data set for each job: job address, installer name, completion date, tile type, roof area, detailed installation checks, customer sign-off, general notes, and any issues found.

• Lets installers attach images either by snapping photos inside the app or by selecting existing shots from their gallery.

• Generates a clean PDF or HTML report and emails it automatically to our office inbox once the form is completed.

• Stores submissions offline when signal is weak and syncs the moment a connection returns.

I’m open to React Native, Flutter, or any cross-platform stack that keeps maintenance light and deployment swift. Just give me the compiled apps plus the full source code, along with a brief user guide so new installers can pick it up on day one.
