Why calculating ROI on a roofing sales rep matters

A good sales rep can be a growth engine. A bad one can burn through your margins fast.

Most roofing companies underestimate the real cost of hiring—benefits, ramp-up time, or the tools reps need to close. This calculator helps you see the full picture, not just the paycheck.

According to JobNimbus Peak Performance 2024 data, roofing companies that invest in a defined sales process with dedicated reps see:

• 32% faster revenue growth
• 4–6× annual ROI compared to overhead cost
• Higher close rates when paired with a CRM that tracks lead-to-close performance
  

If you’re wondering whether it’s time to scale your team, this is your proof point.

How to use the calculator (Step-by-Step)

1. Enter base salary – What you plan to pay your rep each year.
2. Select commission type – Choose whether commissions are based on gross sales or profit.
3. Adjust commission rate (%) – The percentage your rep earns on each sale.
4. Set jobs sold per month – Estimate how many jobs a rep can realistically close.
5. Add average revenue per job – Your typical contract value.
6. Input gross margin (%) – Profit after COGS.
7. Add benefits & payroll (%) – Employer taxes, insurance, and benefits.
8. Include ramp-up time – Months before the rep is fully productive.
9. Add hiring cost – Recruiting, onboarding, and training.
10. Add tools/software cost – CRMs, phones, vehicles, or anything else that supports sales performance.

Interpreting your results

Once you calculate:

• Annual revenue generated shows what that rep should bring in.
• Total compensation + benefits tells you the all-in cost.
• Gross profit accounts for cost of goods sold.
• Net profit from rep reveals your true gain or loss.
• Break-even month shows when they’ll start paying for themselves.

If your net profit and break-even look healthy, congrats—you’re ready to hire.

If not, tweak assumptions like deal volume, margins, or commission structure to find your sweet spot.

Example scenario

Let’s say you hire a roofing sales rep at a $60,000 base salary, with 10% commission on gross revenue, selling 12 jobs/month at $12,000 per job, and 35% margin.

Your rep would generate roughly $1.7M in annual revenue, earn $172K in commission, and produce $355K in net profit—breaking even in their first month.

That’s the power of having the right rep with the right structure.
