The Roofing Lead Waste Index: How It's Calculated
Direct Answer
What is the Roofing Lead Waste Index and how is it calculated?
The Roofing Lead Waste Index is a 0–100 estimate of how much of a roofing company's lead investment is lost to unworkable leads — duplicates, wrong numbers, out-of-area requests, price shoppers, and leads that went cold before first contact. It combines four inputs (bad-contact rate, out-of-area rate, slow-response loss, and shared-lead dilution) into a single directional figure. It is a diagnostic estimate, not an audited measurement.
Purpose
Roofers often blame their close rate when the real problem is that a large share of purchased leads were never workable. The Waste Index turns that hidden loss into a single number owners can track, so they can decide whether to fix lead sources, response speed, or both.
Why measure waste, not just cost
Cost-per-lead looks cheap until you remove the leads that could never close. The Waste Index reframes spend around workable leads, exposing the gap between what you pay and what you can actually act on.
What it does not claim
The index does not assert that a specific vendor is bad or that a specific lead was worthless. It estimates aggregate waste from inputs you provide, and those inputs vary by market, source, and season.
Inputs
- Bad-contact rate (30%)
- Share of leads with wrong numbers, fake info, or no reachable contact.
- Out-of-area rate (25%)
- Share of leads outside your service area or for jobs you don't do.
- Slow-response loss (25%)
- Estimated share of workable leads lost because first contact was too slow.
- Shared-lead dilution (20%)
- Estimated loss from leads sold to multiple contractors at once.
How the calculation works
Waste Index = (BadContact × 0.30) + (OutOfArea × 0.25) + (SlowResponse × 0.25) + (SharedDilution × 0.20)
Each input is expressed 0–100, weighted, and summed. The result rounds to the nearest whole number.Example calculation
| Bad-contact rate | 40 × 0.30 = 12.0 |
|---|---|
| Out-of-area rate | 20 × 0.25 = 5.0 |
| Slow-response loss | 50 × 0.25 = 12.5 |
| Shared-lead dilution | 60 × 0.20 = 12.0 |
| Estimated Waste Index | 42 / 100 |
Assumptions & disclaimer
- Inputs come from your own records and estimates and can be imprecise.
- Weights reflect our current view of what drives wasted spend and may be revised.
- The index estimates aggregate waste, not the outcome of any single lead.
- This report is designed to become RooferFuel.ai's ongoing benchmark dataset. Until live client data is available, calculations are based on disclosed assumptions and should be treated as estimates, not guaranteed outcomes.
The Roofing Lead Waste Index is a diagnostic estimate for informational purposes. It does not guarantee savings, lead quality, or revenue, and it is not an audit of any lead vendor. Results vary by market, source, and factors outside RooferFuel.ai's control.
