How to Track Cohort Analysis for Roofing

Most homeowners only buy a new roof once every 20 to 30 years. This makes roofing uniquely challenging: your customer base naturally turns over. Cohort analysis helps you work smarter by showing which customers refer neighbors, which properties will need repairs soon, and where your marketing dollars generate the best return.

Why Cohort Analysis Matters for Roofing

Track referral patterns. Some neighborhoods generate more referrals than others. When customers from a specific HOA or subdivision refer three neighbors, cohort data tells you to focus advertising there.

Predict repair cycles. A roof replaced five years ago may need minor repairs now. Cohorts based on installation date help you time follow-up outreach precisely when customers are most likely to need service.

Measure marketing ROI. Did that Google Ads campaign in March bring customers who converted at a higher rate than the Facebook ads in April? Cohort analysis by acquisition source answers this.

Build a service niche. Even if most customers never need a second roof, many need gutters, siding, or emergency repairs. Cohorts reveal these cross-sell opportunities.

How to Check in GA4

Create a cohort report in GA4:

1. Open Explore and choose User Cohort
2. Set the cohort basis to First session date
3. Select Weekly granularity
4. Add Conversions as your primary metric

Track two key numbers for roofing:

• Lead-to-job conversion rate by cohort month
• Referral rate: how many customers from each cohort refer at least one other customer

Look for cohorts with referral rates above 15%. These represent your most satisfied customers and best marketing sources.

The Easier Way

ClawAnalytics integrates with your roofing CRM and automatically builds customer cohorts based on actual project data.

Questions ClawAnalytics answers for roofers:

• Which neighborhoods have the highest concentration of roofs over 15 years old?
• What’s the average time between our initial roof replacement and a customer’s first repair request?
• Which customers have referred multiple neighbors, and can we thank them with a loyalty discount?

You get a dashboard showing Customer Lifecycle by Project Type. Instead of guessing, you see exactly when to reach out to past customers about gutters, siding, or that aging roof on the house next door.

Quick Wins

1. Tag roof installation dates in every project. This lets you create precise cohorts based on when each roof was installed, not just when the customer first contacted you.

2. Create a neighborhood outreach calendar. If cohort data shows certain areas have clustering of aging roofs, schedule direct mail or door-knocking campaigns six months before storm season.

3. Develop a referral reward program. Cohorts show which customers generate the most referrals. Offer them a discount on future services or a thank-you gift.

4. Follow up at the 5-year mark. Most roofs need minor repairs around year five. Send a friendly check-in letter offering a free inspection.
