This guide covers procedures that apply in Poland. Before commissioning any work, ask your local municipality whether applications are open and which costs the scheme covers. Asbestos programmes often pay for taking down, collecting, moving and disposing of waste, yet they do not always include a new roof covering. Request the scheme documents and divide your estimate into two parts: asbestos removal and fitting the new roof. Also confirm who settles with the contractor and what own contribution applies.

Start by checking the structure and deciding what needs repairing before you think about the material. Look at the roof from outside and, where possible, at its framework in the attic. Search for signs of water ingress, sagging, damaged timber and worn connections. A new top layer will not remove old faults. If load-bearing capacity is uncertain, ask a structural engineer for an opinion. Where asbestos is suspected, identify what will be removed.

In Poland, concealed gutters can suit a house with a metal roof, but only if the entire eaves detail is designed, not just the gutter hidden behind a fascia. Before deciding, check the system cross-section and establish which parts will remain accessible for cleaning and where water will leave the building. Pay attention to the sheet ending, flashings and gutter position relative to insulation. Also consider emergency overflow and whether the cover can be removed. The solution makes sense when the building form and design allow for it from the start and the contractor knows the details.

In Poland, choosing gutters for a metal roof depends primarily on the roof geometry and the arrangement of outlets, not on colour or shape alone. It is worth preparing a roof plan with dimensions, pitch and eaves lengths, marking valleys and places where water flows from several surfaces, and planning the position of downpipes. These affect the system's capacity. The selection should take into account the assumed rainfall conditions and the system's calculation rules, not merely a rule once used on a similar house.
