Roofing Lead Qualification + WhatsApp Icebreakers with n8n

Capture roofing leads, qualify intent with AI, and message prospects on WhatsApp—fully automated with n8n

This n8n workflow routes every new roofing inquiry from an n8n Form into Google Sheets, uses Google Gemini to score buying intent and draft a tailored WhatsApp icebreaker, alerts your team in Slack for high-intent leads, and sends an autofilled Cal.com scheduling link—without manual follow-up.

What this workflow does

• Receives new lead submissions from an n8n Form (contact details + inquiry message).
• Normalizes and validates data, including phone number validation, and creates a dedupe key.
• Deduplicates in Google Sheets: if a matching lead already exists, the workflow posts a note to Slack and stops further outreach.
• Updates/records new leads in Google Sheets, then calls Google Gemini with a structured prompt to:
  • classify buying intent
  • generate a score
  • draft a WhatsApp icebreaker message
• Routes by intent: for High intent leads, it notifies Slack for immediate sales attention.
• Sends WhatsApp automatically for High/Medium intent leads when a valid WhatsApp number exists and no prior “WhatsApp sent” flag is recorded in Google Sheets.
• Autofills scheduling using a Cal.com scheduling URL (prefilled name/email/notes) and includes it in the WhatsApp outreach.
• Tracks outcomes in Google Sheets: marks WhatsApp sent, disqualified (Low/Spam), or skipped due to invalid phone number.

Use cases

• Instant follow-up for homeowners submitting roofing quotes via an n8n Form
• AI-assisted lead qualification to prioritize high-intent roofing prospects for your sales team
• Preventing duplicate outreach by deduping and flagging WhatsApp-sent status in Google Sheets
