Real-World Calculation: How a 5-Person Roofing Company Saves 20 Hours a Week with Digital Measurements

The number of commercial employees in the roofing trade is 61,723 people - a decrease of 1.0% compared to the previous year. The reason: retiring specialists from the Boomer generation cannot be fully replaced by younger talent, even though the number of trainees is growing.

For a 5-person roofing company with a full order book, this means: every hour of work counts. And yet, week after week, dozens of hours are lost in one process that has barely become more efficient in decades - traditional roof measurement with ladder, folding rule, and notebook.

This article shows you, with concrete numbers, how much time and money you really save by switching to digital drone-based measurement - and how quickly the Airteam Flatrate pays for itself.

The problem: Measurement costs more time than you think

Ask yourself honestly: how long does your company really need for a complete roof measurement - from the first drive out to the finished quote?

Most owners would spontaneously estimate 2 to 3 hours. The reality looks different when you count every step:

• Travel & on-site preparation: 1 hour (drive + setup)
• Roof access & measuring: 2.5 hours (climbing ladders, measuring areas, drawing sketches)
• Data rework & transfer: 1.5 hours (transferring hand sketches to the office, typing in measurements)
• Costing & quote creation: 2 hours (calculating material requirements, preparing proposal documents)
• Corrections & follow-up questions: 45 minutes (inaccurate dimensions, later corrections)

Total: around 7.75 hours per measurement. For a company that measures 4 properties per week, that's a good 31 working hours every week spent purely on the measurement process - almost one full working week of a skilled worker.

This is exactly where modern construction measurement software and a digital measuring tool for construction like Airteam come in.

Step by step: What really costs time

To make it clear where the hours are lost, here is a typical process in comparison:

The digital workflow with the Airteam Fusion Plattform works fundamentally differently:

1. Drone flight on site (~15-20 min): One person flies the drone once around the building. No roof access required - safe operation from the ground.
2. Upload & AI processing (~automatic): The images are uploaded to the cloud. Within a few hours, the AI generates a DIN-compliant 3D model.
3. Data export & quote (~30 min): The finished measurement data flows directly into your costing or job costing for contractors software - no manual typing.

Result: ~1.4 hours instead of 7.75 hours - a saving of more than 6 hours per measurement.

The cost calculation: What this means for your business

Now let's get specific. We will use a realistic charge-out rate of €50/hour - a conservative average for an experienced roofer who, under the applicable collective agreement, earns an hourly wage of over €21, plus social costs and overheads.

What these numbers mean:

• With the roughly 25 hours saved per week, your company can take on additional jobs or complete existing projects faster.
• Every additional job - even a small repair roof - generates several hundred to several thousand euros in contribution margin.
• The Airteam Flatrate is minor compared to the personnel costs you save.

This also makes your time tracking for contractors much easier, because measurement time becomes predictable and significantly shorter.

The often underestimated factor: Errors cost money

In addition to the pure time spent, there is another often underestimated cost factor: measurement errors and rework.

Anyone who has ever ordered too much material due to inaccurate measurements - or worse, too little - knows the frustration. Typical follow-on costs in the traditional measurement process include:

• Additional material deliveries when you under-order: express fees, waiting time on site
• Returns or storage when you over-order: logistics effort, tied-up capital
• Extra trip for remeasurement: time and travel costs
• Corrected quotes after customer questions: loss of reputation, wasted office time

The Airteam Fusion Plattform delivers DIN-certified accuracy of up to 99.9% with a tolerance of 1-3 cm at a flight height of 40 m - that is eight times more accurate than satellite data. When you calculate with this data, you avoid errors structurally, not by chance.

If you factor in just one avoided remeasurement visit per week (2 hours travel + measurement = €100 personnel costs), your weekly savings increase even further.

More jobs through faster quotes

Another business case that often gets overlooked: the faster you cost a project, the more jobs you win.

In roofing, customers often decide after the first or second quote. Demand remains high, full order books are the norm - but at the same time, the shortage of skilled workers makes capacity and quality more challenging.

With digital measurement, you benefit from:

• Quotes within 24 hours instead of 3-5 days: you are often the first to respond.
• Professional 3D visualisation in your proposal: customers see their roof digitally - this builds trust.
• Fewer lost quotes due to errors: precise data = convincing figures.

As master roofer Harnack shares in his success story, he saves 90% of the time on roof measurement with Airteam - and wins the capacity to serve more customers professionally.

When does the investment pay off?

Let's take the most conservative scenario: a company starts with an Airteam Starter Set - including drone, software, training, and support.

With a weekly net saving of around €1,340 (4 measurements × €50/h × 6.35 h time saved minus Airteam costs), the payback period is just a few weeks to a few months - depending on the starter model you choose.

If you want to start without your own drone at first, you can book Airteam pilots and use the Flatrate models flexibly - then there are no upfront hardware costs, and your savings start with the very first job.

Real-world numbers confirm this: Dachdeckerei Mann GmbH used Airteam to measure 6,000 m² of roof area with over 100 dormers in just 2 days - instead of in weeks. A clear proof that digital measurement makes a measurable difference not only for small projects, but also for complex jobs.

Conclusion: The calculation is clear

You cannot simply wish the shortage of skilled workers away - but you can compensate for it by working smarter. A 5-person company that carries out 4 digital measurements per week wins back around 25 working hours. That is more than half an extra full-time position in available capacity - without hiring a single new employee.

The key numbers at a glance:

• ~6.35 hours saved per measurement (from ~7.75 h down to ~1.4 h)
• ~25 hours less measurement effort per week with 4 projects
• Up to ~€1,340 net savings per week (at a €50/h charge-out rate)
• Payback on the drone investment in just a few weeks
• More quotes thanks to faster costing = more revenue

For companies that see themselves reflected in this calculation, it is worth taking a look at the Airteam success stories - and of course at your own ROI using the calculator above.

The first step is easier than you think: you can test Airteam free for 14 days and without risk. No long onboarding, no CAD expertise required - just fly, upload, done.
