Plumbing work is almost always custom-made, which explains the price differences. A key cost factor is the material chosen. Aluminum and galvanized steel are considered economical solutions, while titanium zinc and copper are significantly more expensive but offer a very long service life. The accessibility of the work surface also plays a major role.
Steep roofs, great heights, or areas that are difficult to access require additional safety measures, scaffolding, or longer installation times. Another factor is the roof geometry. Complex connections to dormers, chimneys, or skylights require precise manual work and increase the amount of effort required. In addition, hourly rates vary from region to region.
In metropolitan areas, these are often higher than in rural areas. Special requests such as individually curved profiles or custom-made products can further influence the price. It is therefore worth comparing several quotes carefully – not only in terms of price, but also in terms of material quality and design details.
