OneRooff is a roofing solutions company that needed a way to provide 24/7 customer support on WhatsApp without hiring a full-time support team. The solution was an AI-powered WhatsApp agent that handles customer inquiries, provides quotes, answers FAQs, and routes complex issues — all automatically through WhatsApp, the platform their customers already use daily.

The entire system is orchestrated through Make.com (formerly Integromat), which acts as the central automation hub connecting all services together. When a customer sends a message on WhatsApp, the flow is as follows:

The automation stack is built with reliability and scalability in mind. Make.com serves as the workflow engine, connecting 360Dialog (WhatsApp Business API provider) for message sending and receiving, Supabase for persistent chat session storage and user context, and Vapi.ai for the AI agent that understands roofing-related queries and provides accurate, helpful responses. The session management in Supabase ensures that the AI agent remembers previous conversations, creating a seamless experience for returning customers.

The WhatsApp AI agent has transformed OneRooff's customer support operations. Customers now receive instant responses at any time of day, whether they're asking about roofing services, requesting a quote, or following up on an existing inquiry. The automation has significantly reduced response times from hours to seconds, improved customer satisfaction, and freed up the team to focus on actual roofing work instead of being tied to their phones answering repetitive questions.
