Roofing Project Management Platform

I need a web application that lets both homeowners and roofing contractors submit project details, have those details verified, and manage every step of the job from one dashboard. The core workflow is straightforward: a homeowner (or contractor) fills in a structured form, uploads plans, photos, and measurements; the system routes the submission to the appropriate party for verification; once approved, everyone involved can track progress, update documents, and see real-time status changes.

Key functions I expect to see in your solution
• Role-based accounts for homeowners, contractors, and administrators
• Clean, responsive UI for form submission and document upload (desktop & mobile)
• Verification workflow with notification triggers and an auditable approval log
• Project dashboard showing milestones, messages, and file history
• Secure data storage with routine backups and permission controls
• Deployment script and user/admin documentation so I can maintain the platform after launch

Please send a detailed project proposal outlining your preferred tech stack, architecture, timeline, and any post-launch support options. Source code, build instructions, and a short hand-off session are required on delivery so I can run and extend the platform confidently.
