Thanks for sharing the photos. There is one showing a metal rooftop with logs and rocks on top. Why are the logs and rocks on top of the roof?

- bahador 10y agoIt's probably a temperature thing? A metal roof probably gets really hot. I have no idea what the temperatures there are though...
- cr1895 10y agoNot OP but I'd guess they're to help keep the sheet metal from blowing off the roof.
- kweks 10y agoRight, I had always assumed that it was to keep the roof on. For the reply below, temperatures vary wildly, as it's in altitude - even between the shade and sun in summer, there's a large variation, and in winter, it gets coooold.
- JulianMorrison 10y agoI've seen the same sort of thing in pre-industrial-era Japanese house design. My guess, is that although the roof is fixed down, it helps to have it also weighted down with big rocks when the wind picks up. Japan gets typhoons, and I think Tibet is kinda windy on account of being high up.
