1. Why Roofing Labor Costs Matter

Roofing companies face many overhead expenses, such as equipment, materials, and insurance. But labor costs are often the biggest expense. If you don’t handle your labor costs carefully, you can end up paying too much or too little. Overpaying may cut into your profits, while underpaying can hurt employee morale and cause high turnover.

A solid labor plan helps you:

• Budget for upcoming projects more accurately
• Keep your crew satisfied
• Prevent surprises when it’s time to run payroll
• Make data-driven decisions about where to invest your resources

Understanding your labor costs in real time is important, too. Having tools to track each worker’s hours or each square of roofing they complete helps you keep your projects under budget and on schedule. When you can see how much a project is costing day by day, it’s easier to make changes quickly, so you don’t get blindsided by large overruns at the end.

Calculating Costs With an Hourly Pay System

How It Works

An hourly system means you pay your crew members based on how many hours they work each day. If the average hourly rate for a roofing crew member is about $30 per hour, then you’d multiply the total hours worked by $30 to get your labor cost for that period.

Pros of Hourly Pay

• Simplicity: It’s very straightforward to track time if you have a clock-in/clock-out system.
• Predictability: If you have a good idea of how many hours a job will take, you can estimate labor costs more easily.
• Worker Satisfaction: Many employees like the security of a steady hourly wage.

Cons of Hourly Pay

• Slower Work Pacing: If people get paid the same rate regardless of how many squares they complete, they might work more slowly.
• Overestimation: If you miscalculate how many hours the job will take, your costs could skyrocket.
• Less Motivation: Crew members might focus on clocking hours rather than finishing tasks efficiently.

Estimating Hourly Costs

To estimate your labor using hourly pay, consider these steps:

1. Look at Past Projects: Track the number of hours your crew needed to install each square of roofing. Let’s say your team usually does one square in about an hour per person.
2. Set an Hourly Rate: If your average crew member makes $30 per hour, multiply it by the total hours your project will need. For example, if you have a 30-square roof, that’s roughly 30 hours to install. Multiply 30 hours by $30/hour to get $900 as a starting labor estimate. Do the same for the tear off.
3. Adjust for Complexity: If the roof is more complex, steep, has additional layers to remove or doesn’t have access then you’ll have to add additional time in to make up for that.

Calculating Costs With a Piece Work System

How It Works

With a piece work system, you pay each crew member for each “piece” they complete. In roofing, a common piece is a “square,” which is 100 square feet of roofing material installed. If you decide to pay $30 per square, you’d multiply the total number of squares installed by $30.

Pros of Piece Work Pay

• Productivity: Crews often work more efficiently because their pay is tied to the amount of work done.
• Budget Friendly: You know exactly how much you’ll pay per square, so your labor cost is easier to predict if you know how many squares a project needs.
• Clear Goals: When workers see exactly how many squares they’ve installed, it becomes a measurable goal they can meet and exceed.

Cons of Piece Work Pay

• Quality Concerns: Some people might rush to finish as many squares as possible, so you need quality checks.
• Inconsistent Paychecks: If the crew doesn’t get enough work or if weather is bad, their income can drop.
• Pacing and Team Differences: Some workers install faster than others, which can create big pay gaps if you’re not careful to assign tasks fairly.

Estimating Piece Work Costs

1. Decide on a Rate Per Square: If the average rate is $30 per square, multiply that by how many squares the roof will require. Do the same for tear off.
2. Add Piece Rates For Details: Most roofs aren’t just a straight slope. You’ll need to decide how to pay your crew for additional details like chimneys and skylights, as well as how the pay scales for steeper roofs.
3. Consider Team Efficiency: If you have a mix of slower and faster workers, your overall progress might even out, but you’ll still pay per completed square, so keep an eye on how consistently squares get done.

4. Using a Hybrid System

You might have heard about a mix of hourly and piece work called a hybrid system. In a hybrid system, you pay a lower hourly rate plus a small piece rate for each square completed. For example, you might pay $20 per hour plus $10 per square installed. The base hourly wage ensures workers don’t worry about not getting enough squares if the job runs into delays or if they have tasks that aren’t tied to a piece rate (like cleanup or prep work). The piece rate on top of that encourages them to keep up a good pace.

Pros of a Hybrid System

• Steady Income + Incentive: Crew members have some stability with the base hourly pay, plus motivation to work quickly for additional piece rate pay.
• Reduced Abuse: If done well, it’s harder to “game” the system because you don’t pay a full hourly rate and a full piece rate separately.
• Flexible: Tasks that don’t fit a piece rate model can still be covered by the hourly portion.

Cons of a Hybrid System

• Complexity: You need a solid tracking system to handle both hourly and piece work data.
• Rate Balancing: Figuring out the right balance of hourly wage and piece rate can take time.
• Risk of Overlapping Payment: If not managed properly, some workers might stretch their hours while also getting paid for squares completed, which could blow your budget.

Tracking and Job Costing

Why Tracking Matters

No matter which pay method you choose—hourly, piece work, or a hybrid—accurate tracking of labor is critical. You can’t improve what you don’t measure. Having a system that records clock-in/clock-out times and the number of squares installed each day is a strong first step. When you know exactly what each worker did, you can approve time cards, calculate wages, and pay your crew correctly.

Using Job Costing Reports

Job costing reports break down how much money you’ve spent on each aspect of a project. If you’re paying hourly, you’ll see the total hours and total wages for each job. If you’re paying piece work, you’ll see how many squares were completed and how much it cost you per square. These reports can help you figure out:

• How your actual labor costs compare to your original estimates
• Which jobs stayed under budget and which went over
• How quickly your crew completed tasks

By reviewing job costing reports regularly, you’ll see where you might need to adjust your rates or crew assignments. Maybe one crew is faster than another, so you can plan more demanding jobs for that team. Or maybe certain projects take much longer than anticipated, so you need to tweak your estimates.

Tools and Software

Manually tracking hours and squares can be time-consuming and prone to errors. That’s where a specialized tool can help. Software like Piece Work Pro (the system we created to track our crews) can take the guesswork out of tracking. It allows each crew member to clock in and record their piece work, and you can quickly see how much you’re paying out per job. With clear data at your fingertips, it’s simpler to do payroll, identify problem areas, and plan for the future.

Staying Profitable Through Better Tracking

Beyond just paying your crew, remember to keep the bigger picture in mind. If you track how much labor costs you each job, you can make better decisions about staffing, materials, and scheduling. You’ll also have a clearer idea of which pay model—hourly, piece work, or hybrid—makes the most sense for each project.

When you review your job costing reports, ask yourself:

• Are my crews finishing faster or slower than expected?
• Did I budget enough for labor, or did I run short?
• Is my current pay model motivating people to work efficiently without sacrificing quality?
• Are there particular tasks or project types that would benefit from a different pay method?

Over time, you can use your tracking data to refine your operations. You might discover that one model works better in the busy summer months, while another works better when you have smaller, more specialized projects. Or you may find that a hybrid approach is the perfect mix of stable pay and performance-based rewards.

Conclusion

Calculating roofing labor costs doesn’t have to be overwhelming. By choosing the right pay model for your company—hourly, piece work, or a well-structured hybrid—and using strong tracking and job costing methods, you can keep your crews motivated and ensure each job remains profitable. Start by estimating costs carefully. Then, track your actual spending in real time so that you can stay under budget and address issues as they come up.

Remember that every roofing business is a bit different. What works for one might not work for another. The key is to keep good records, stay flexible, and regularly evaluate whether your pay model and tracking system are meeting your goals. With the right approach, you’ll be able to pay your workers fairly, attract top talent, and maintain a healthy bottom line on every roofing job.
