Roofer vs. sheet metal worker: two trades, one roof - differences & similarities
*The image was AI-generated for illustrative purposes.
Roofers and sheet metal workers are two skilled trades that are essential on every roof. They work closely together but have different areas of focus and responsibilities. In this article, Roofify explains the key differences and similarities, and why roofers are increasingly taking on sheet metal work as well. You'll also learn which tools and skills are characteristic of both professions - and why teamwork on the roof is more important than ever.
Why roofers and sheet metal workers are important for every roof
Whether for new construction, renovation, or repairs, the quality of a roof depends on the collaboration of various trades.
- Roofers are responsible for waterproofing, roofing, and the roof structure.
- Sheet metal workers handle metal components such as gutters, sheet metal flashings, and folded profiles.
Especially in 2026, as roofs are expected to become increasingly complex, sustainable, and durable, both professions are more important than ever.
Roofers: Waterproofing, roofing & protection
Roofers' tasks
Roofers ensure that roofs are weatherproof. Their main tasks include:
- Roofing with tiles, slate, or concrete roof tiles
- Flat roof waterproofing
- Insulation and energy-efficient renovations
- Installation of roof windows, fall protection systems, and solar technology
- Repairs and maintenance
A master roofer also handles planning, customer consultations, and project management - an important part of modern construction projects.
Roofing tools
Professional roofing companies rely on high-quality roofing tools, including:
- Slate hammer and slate nailer
- Claw hammer and carpenter's square
- Utility knives, tin snips, and circular saws
- Gas torches for bitumen waterproofing
- Personal protective equipment for working at height
Modern roofers increasingly use digital tools such as drones for inspections and laser measuring devices for precise planning.
The sheet metal worker: metalwork on roofs
What does a sheet metal worker do?
A sheet metal worker (also called a “tinsmith,” “flaschner,” or “plumber” in Southern Germany and Austria) specializes in working with metal around the roof. Typical tasks include:
- Gutters and downpipes
- Sheet metal flashings and connection plates
- Metal cladding for dormers and chimneys
- Metal roofs made of aluminum, zinc, copper, or stainless steel
- Custom-fabricated edge profiles for demanding roofs
An experienced master sheet metal worker ensures that all components fit to the millimeter and the roof is optimally protected.
Sheet metalworking tools
Typical sheet metalworking tools include:
- Folding bench & beading machine
- Seaming pliers, planishing hammer, chasing hammer
- Tape measure, templates, tin snips
- Soldering tools for metal joints
These tools enable the precise shaping, seaming, and installation of sheet metal - a craft that takes considerable experience.
Regional differences: sheet metal worker, plumber, or tinsmith?
Trade names and traditions differ by region:
Southern Germany and Austria
In Bavaria, Baden-Württemberg, and Austria, the term sheet metal worker is widely used. Here, sheet metal work is a distinct, highly respected trade with a clearly defined scope of work.
Northern Germany
In northern Germany, people tend to use the terms Klempner or Blechner. However, the work is comparable: metalwork on roofs.
Switzerland
In Switzerland, sheet metal workers are often called Flaschner. The training is technically focused because many Swiss buildings have complex metal roofs.
Why are roofers taking on more and more sheet metal work?
Requirements in the construction trades are changing. Key reasons why roofers are increasingly taking on sheet metal work in 2026:
- More complex roofing systems: Modern roofs consist of many components, such as transitions, dormers, solar panel mounts, and ventilation pipes. Precise metalwork is in demand.
- Skilled labor shortage: Some regions, especially rural areas, lack sheet metal workers. Roofers take on typical sheet metal work to prevent construction projects from being delayed.
- Efficiency in the construction process: Site managers prefer businesses that can handle multiple tasks. Roofers therefore receive training in sheet metal work such as gutter installation and sheet metal coverings.
- Business benefits: A broader range of services offers more opportunities to win contracts, better customer retention, and greater flexibility.
Many businesses work closely with sheet metal workers or employ their own metalworkers on the team.

Differences between roofers and sheet metal workers - at a glance
Training
- Roofer: 3 years of dual training, focusing on roof covering, waterproofing, and insulation
- Sheet metal worker: 3–3.5 years of training, focusing on metalworking, soldering, and folding
Materials
- Roofer: Tiles, slate, bitumen, wood
- Sheet metal worker: Zinc, copper, aluminum, sheet steel
Work
- Roofer: Roof covering, waterproofing, maintenance
- Sheet metal worker: Gutters, sheet metal cladding, metal profiles
What they have in common: Why both professions make a team
Precision and responsibility
Roofers and sheet metal workers work on the most sensitive part of a building: the roof. Mistakes can cause costly damage. Both professions must:
- Work precisely
- Use suitable materials
- Know and follow building standards
Durability and sustainability
Demand is growing for sustainable materials such as copper, titanium zinc, and recyclable roof tiles. Roofers and Spenglers are in demand for modern energy and water management systems.
Two professions, one goal
Roofers and Spenglers are indispensable partners on the roof. While roofers take care of the basic waterproofing and roofing, Spenglers handle precision metalwork. Together, they make buildings weatherproof, energy-efficient, and visually appealing—in Germany, Austria, and Switzerland.
With the expertise of master roofers and master Spenglers, the result is a roof that is functional and technically first-rate. More and more roofing businesses are therefore expanding their services to include sheet metal work, so that property owners benefit from a single point of contact and seamless planning.
Frequently Asked Questions
What is the difference between a roofer and a Spengler?
Roofers specialize in waterproofing, roofing, and insulating roofs. Spenglers (also called Flaschner, Klempner, or Blechner) work with metal on roofs, for example making gutters, sheet metal coverings, and metal profiles. The two professions complement each other on the construction site.
How long does it take to train as a roofer or Spengler?
Training to become a roofer usually takes 3 years, while training to become a Spengler takes 3 to 3.5 years. Both programs are dual, combining on-the-job experience with theory at vocational school.
What tools do roofers and Spenglers need?
Roofers use tools such as slate hammers, lath hammers, tin snips, gas torches, and personal protective equipment. Spenglers work with folding brakes, seaming pliers, soldering tools, and various hammers. Modern businesses also use digital measuring devices and drones.
Why are roofers taking on more and more sheet metal work?
Due to more complex roofing systems, a shortage of skilled workers, and efficiency considerations, roofers are increasingly taking on sheet metal work. This allows them to offer complete solutions, complete construction projects faster, and benefit economically.
What are Spenglers called in other regions?
In southern Germany and Austria, “Spengler” is the common term, while in northern Germany people say “Klempner” or “Blechner,” and in Switzerland, often “Flaschner.” However, the tasks are similar.
