Flexible roof tiles, very convenient if you have complex slopes. I have just these, with dormer-windows, broken. Than to cut a metal tile, I preferred flexible, as you want, and you stack it. Of course, there are also difficulties, everyone decides for himself. I chose the soft roof of Ruflex Ornam, cut in semicircles, the color is red clay. In Rufstroy, they gave me a preliminary calculation, based on materials and money, then I went to see in their office what Ruflex looks like in real life. Prices arranged, looking even better than in the photo. And stable, neither afraid of heat nor cold. Immediately in Rufstroy and bought, agreed on delivery in a few days. However, for some reason they didn’t bring everything at once, several packages were not enough, apparently miscalculated during shipment. It happens. I did not make noise, especially since they apologized to me a day later for free. A roof with flexible tiles looks great, and what's good, it eliminates all the noise, even in a shower under the roof almost nothing is heard.
pros
Lays down on any roof, looks very good, does not pass noise
