Start Tracking Roofing Leads Free →In residential roofing, a single storm season or a few months of heavy Google Local Services Ads (LSA) spend can bring in dozens of lead inquiries. Yet every year, high-volume roofing contractors find themselves cash-flow poor despite completing hundreds of jobs. The primary culprit is miscalculating the true Maximum Allowable Customer Acquisition Cost (CAC).
When contractors evaluate marketing budgets, they often look only at gross profit after materials and labor—ignoring the real impact of sales commissions, office overhead, warranty reserve funds, and the two-stage drop-off rate between inbound lead, scheduled inspection, and signed contract.
For example, if your average full replacement is $13,500 and materials plus crew cost $7,800, you have $5,700 in gross profit. But after paying a 10% gross sales commission ($1,350) and preserving an 18% net profit target ($2,430), your actual ceiling for client acquisition is $1,920 per closed job. If it takes 15 raw inquiries to close one roof, your absolute maximum bid per raw lead is $128.
Not all roofing leads convert or cost the same. Understanding the economics of each acquisition channel prevents you from overpaying on low-intent platforms:
Google Local Services Ads (LSA) & PPC: These capture high-intent retail buyers or homeowners suffering active leaks. While cost per lead is higher ($60–$160), close rates on completed inspections frequently exceed 35% because the homeowner initiated the search.
Shared Lead Platforms (Angi, HomeAdvisor, Modernize): While the upfront lead cost looks attractive ($30–$70), these leads are sold to 3–5 competing roofers within seconds. Blended close rates often drop below 8%, making the effective cost per closed job far higher than exclusive Google traffic.
Door-to-Door & Storm Chasing Campaigns: In post-hail environments, canvassing produces high volume at a low direct lead acquisition cost. However, the heavy burden shifts to sales commissions (often 40–50% of gross profit) and lengthy insurance claim processing cycles.
| Channel | Typical Lead Cost | Avg Inspection Close Rate | Effective Cost/Job |
|---|---|---|---|
| Google LSA (Verified Calls) | $55–$120 | 25–40% | $250–$480 |
| Google Search PPC (Exclusive) | $80–$180 | 20–35% | $400–$900 |
| Facebook / Instagram Ads | $30–$70 | 10–20% | $300–$700 |
| Shared Aggregators (Angi) | $35–$75 | 5–10% | $500–$1,500 |
| Direct Mail / Storm Radius | $40–$90 | 15–25% | $350–$600 |
Across the United States, the average cost per closed residential roof replacement ranges from $350 to $900. Contractors with dialed-in call answering and rapid inspection booking processes consistently stay at the lower end ($350–$500), while those with slow follow-up times drift over $1,000 per closed job.
Sales commissions directly compete with your marketing budget for gross profit. If your company pays a 10% to 12% top-line commission on a $15,000 roof ($1,500 to $1,800), your maximum allowable marketing acquisition ceiling drops substantially. To maintain healthy cash flow, many contractors adjust commission tiers when jobs are generated via expensive company-paid digital advertising vs. rep-generated referrals.
Tracking only form submissions and phone calls creates misleading data because a $40 lead from Facebook might produce zero signed contracts while a $140 lead from Google PPC turns into a $22,000 roof replacement.
