In most cases, plumbing work is customized to individual requirements. The most important cost factor is the material chosen. Aluminum and galvanized steel are considered economical, while titanium zinc and copper require higher investments but are particularly durable.
Accessibility also influences the price. Steep roofs, great heights, or confined spaces require additional safety measures, scaffolding, or longer installation times. The shape of the roof also plays a role: many connections, valleys, or transitions at dormers and chimneys significantly increase the amount of craftsmanship required.
In addition, there are regional differences in labor costs and custom-made products such as specially bent profiles or individual detail designs. It is therefore always worth comparing quotes—not only in terms of price, but also in terms of material thickness, fastening systems, and quality of workmanship.
