What roofing coating would you recommend for a 10-degree single-pitch roof? Tintan galvanized sheet or trapezoidal sheet roofing or tile roofing? What are the advantages/disadvantages? With a tile roof, we are only talking about flat tile (e.g. Tegalite) because we would like to have only that. Will an under-roof with rain protection be mandatory?

There will also be a photovoltaic system installed on the roof.

We cover the roof with trapezoidal steel sheets for our 6° single pitch roof. Unfortunately, I can't tell you about my experience yet since we haven't moved in yet, but it's already waterproof.

here are roofing recommendations for this. Up to 7° (5°) typically trapezoidal sheets, Eternit wave, zinc seam roofing. possibly double seam, etc. goes. Depending on the requirements, you may need a waterproof roof UNroof with sealed counter battens. With specially designed shingles (Braas) presumably a durable roof covering in the 12°-7° range is possible. Whether this really makes sense and looks good remains to be questioned. Clean waterproofing with roofing membranes is also usually possible, but it must be ventilated and either be approved by the building authorities as a "soft roof" in the appropriate situation (bitumen membranes), have a gravel load of at least 5 cm, or meet fire safety requirements as a plastic/elastomeric waterproofing membrane with building authority approval. Therefore, the decision in favor of one or the other material depends first of all on the construction, then on the design and finally on the price. Panel roofing and trapezoidal sheets are pretty close in price, including all the extra work. Eternite is about 1/3 more expensive, zinc roofing is about 2-3 times more expensive, depending on the shape of the roof.

Neither; below 12° always bitumen and then slate.

Installing a PV system is always possible, regardless of roofing.
