Most roofing businesses run on gut feel. You know which months are busy, which types of jobs pay well, and which customers are a headache. But you probably can't quantify it. AI changes that — not by writing emails, but by reading your actual business data and telling you what's happening.
If your job data is in Excel, Google Sheets, or a job management tool, you can ask AI:
With Copilot in Excel: "Analyse my job costs for the last 12 months. Break down by job type (re-roof, repair, maintenance). Show me which type has the highest profit margin and which has the lowest."
With Claude Cowork: Point it at your quote spreadsheet and your actual job cost spreadsheet. Ask: "Compare what I quoted vs what each job actually cost. Where am I consistently underquoting?"
This is the kind of analysis that would take an accountant 3 hours. AI does it in 30 seconds. And it's reading YOUR numbers, not giving generic advice.
With Claude Cowork or Copilot: "Here are all my quotes from the last 6 months — which ones converted to jobs and which didn't? What's different about the ones that converted? Is it price, job type, area, or timing?"
You might discover that your residential re-roof quotes convert at 45% but your commercial quotes only convert at 15%. That tells you where to focus your effort.
With Copilot in Excel: "Show me my revenue by month for the last 2 years. What's the pattern? When should I schedule my quiet periods for maintenance contract outreach?"
NZ roofing is seasonal — winter slows down. AI can tell you exactly when to push marketing, when to schedule maintenance work, and when to take holidays.
With Claude Cowork: "Here are all my customers from the last 2 years. Which ones gave me repeat business? Which ones referred other customers? What do my best customers have in common?"
Most roofers don't track this. AI reads your data and tells you. You might find that body corporate work is 3x more valuable than one-off residential repairs.
| What you want | Tool | How |
|---|---|---|
| Analyse Excel job data | Copilot in Excel | Open your spreadsheet, ask in the Copilot pane |
| Compare quotes vs actual costs | Claude Cowork | Give it both files, ask for the comparison |
| Understand seasonal patterns | Copilot in Excel or Google Sheets + Gemini | Ask for monthly breakdown + chart |
| Customer analysis | Claude Cowork | Give it your customer list + job history |
| Quick "what if" calculations | Any AI | "If I increase my day rate by $10, how much extra revenue per month?" |
Before: You guess. You feel like commercial jobs don't pay well but you're not sure. You think winter is slow but you don't know exactly when it starts.
After: You know. You have the numbers. You make decisions based on data, not gut feel. And it took 5 minutes, not 3 hours with an accountant.
