Roofer vs. Plumber: two professions, one roof – differences & similarities
*The image was AI-generated for illustrative purposes.
Roofers and sheet metal workers are two trades that are indispensable for any roof. Both work closely together but have different focuses and tasks. In this article, Roofify explains the key differences, commonalities, and why roofers are increasingly taking on sheet metal work. You will also learn about the tools and skills that characterize both professions – and why teamwork on the roof is more important than ever today.
Why Roofers and Sheet Metal Workers are Important for Every Roof
Whether new construction, renovation, or repair: the quality of a roof depends on the interplay of various trades.
- Roofers are responsible for waterproofing, roofing, and the roof structure.
- Sheet metal workers deal with metallic components such as gutters, flashing, and edge profiles.
Especially in 2026, when roofs are expected to become increasingly complex, sustainable, and durable, both professions are more important than ever.
The Roofer: Waterproofing, Covering & Protection
Tasks of the Roofer
The roofer ensures that roofs are weatherproof. Key tasks include:
- Covering with tiles, slate, or concrete roof tiles
- Waterproofing of flat roofs
- Insulation and energy-efficient renovation
- Installation of roof windows, fall protection, and solar technology
- Repairs and maintenance
A master roofer also handles planning, client consultation, and project management – an important component of modern construction projects.
Roofer Tools
Professional roofing companies rely on high-quality roofer tools, including:
- Slate hammer and slate nailer
- Lathing hammer and framing square
- Cutters, tin snips, and circular saws
- Gas burner for bitumen waterproofing
- Personal protective equipment for working at height
Modern roofers increasingly use digital aids such as drones for inspection or laser measuring devices for precise planning.
The Sheet Metal Worker: Metal Processing on the Roof
What Does a Sheet Metal Worker Do?
The sheet metal worker (also called "Blechner", Flaschner or "Klempner" in Southern Germany and Austria) specializes in metal processing around the roof. Typical tasks include:
- Gutters and downpipes
- Sheet metal flashings and connection plates
- Metal cladding of dormers and chimneys
- Sheet metal roofs made of aluminum, zinc, copper, or stainless steel
- Individual edge profiles for challenging roofs
An experienced master sheet metal worker ensures that all components fit perfectly and the roof is optimally protected.
Sheet Metal Worker Tools
Typical sheet metal worker tools are:
- Brake press & beading machine
- Folding pliers, setting hammer, raising hammer
- Tape measure, templates, tin snips
- Soldering tool for metal connections
These tools enable precise shaping, folding, and mounting of sheet metal – a craft that requires a lot of experience.
Regional Differences: Spengler, Klempner or Flaschner?
The terms and traditions in the trade differ by region:
Southern Germany and Austria
In Bavaria, Baden-Württemberg, and Austria, the term Spengler is widely used. Here, the Spengler is an independent, highly respected profession with a clearly defined scope of tasks.
Northern Germany
In Northern Germany, people tend to speak of Klempner or Blechner. However, the activities are comparable: metalwork on the roof.
Switzerland
In Switzerland, the Spengler is often called Flaschner. The training is technically oriented, as many Swiss buildings have complex metal roofs.
Why are Roofers Increasingly Taking on Sheet Metal Work?
The demands in the construction trade are changing. Important reasons why roofers will increasingly take on sheet metal work in 2026:
- More complex roof systems: Modern roofs consist of many components such as transitions, dormers, solar mounts, and ventilation pipes. Precise metalwork is required. Skilled labor shortage: In some regions, there is a lack of sheet metal workers, especially in rural areas. Roofers take on typical sheet metal work to avoid delaying construction projects.
- Efficiency in the construction process: Site managers prefer companies that cover multiple tasks. Master roofers are therefore trained in sheet metal work such as gutter installation and sheet metal covers.
- Economic advantages: A broader range of services offers higher order opportunities, better customer loyalty, and more flexibility.
Many companies work closely with sheet metal workers or employ their own metalworkers in their team.

Differences Between Roofer and Sheet Metal Worker – At a Glance
Training
- Roofer: 3 years of dual vocational training, focus on roofing, waterproofing, insulation
- Sheet Metal Worker: 3–3.5 years of training, focus on metal processing, soldering, folding
Materials
- Roofer: Tiles, slate, bitumen, wood
- Sheet Metal Worker: Zinc, copper, aluminum, steel sheet
Tasks
- Roofer: Roof covering, waterproofing, maintenance
- Sheet Metal Worker: Gutters, sheet metal cladding, metal profiles
Commonalities: Why Both Professions Form a Team
Precision and Responsibility
Roofers and sheet metal workers work on the most sensitive part of the building: the roof. Errors can cause costly damage. Both professions must:
- Work precisely
- Process suitable materials
- Know and comply with building standards
Durability and Sustainability
The demand for sustainable materials such as copper, titanium zinc, or recyclable roof tiles is increasing. Roofers and sheet metal workers are in demand for modern energy and water management systems.
Two Professions, One Goal
Roofers and sheet metal workers are indispensable partners on the roof. While the roofer takes care of the basic waterproofing and roofing, the sheet metal worker performs precise metalwork. Together, they make buildings weatherproof, energy-efficient, and visually appealing – in Germany, Austria, and Switzerland.
With the expertise of master roofers and master sheet metal workers, a roof is created that is functional and technically at the highest level. More and more roofing companies are therefore expanding their services to include sheet metal work, so that builders benefit from one point of contact and consistent planning.
Frequently Asked Questions
What is the difference between a roofer and a sheet metal worker?
A roofer specializes in the waterproofing, covering, and insulation of roofs. A sheet metal worker (also called Flaschner, Klempner, or Blechner) processes metals on the roof, for example for gutters, sheet metal covers, and metal profiles. Both professions complement each other on the construction site.
How long does the training for a roofer or sheet metal worker take?
The training for a roofer usually takes 3 years, and for a sheet metal worker, 3 to 3.5 years. Both trainings are dual, combining practical experience in the company with theoretical education in vocational school.
What tools do roofers and sheet metal workers need?
Roofers use tools such as a slate hammer, lathing hammer, tin snips, gas burners, and personal protective equipment. Sheet metal workers work with a brake press, folding pliers, soldering tools, and various hammers. Modern companies also use digital measuring devices and drones.
Why are roofers increasingly taking on sheet metal work?
Due to more complex roof systems, a shortage of skilled workers, and efficiency reasons, roofers are increasingly taking on sheet metal work. This allows them to offer complete solutions, implement construction projects faster, and leverage economic advantages.
What are sheet metal workers called in other regions?
In Southern Germany and Austria, "Spengler" is common, in Northern Germany, people speak of "Klempner" or "Blechner", and in Switzerland often of "Flaschner". However, the tasks are similar.
