Can I have a bit of advice, my roof was recently re-done. The trade person had just laid the tile down hanging it on the roof wood bars. He add no nails, while previously there were some nails. I can see that the tile itself had an edge to hang over the wooden bar, but I'm concerned that this is not safe enough. When I asked he said nails are not needed to fix the tile. My roof is pitched by almost 50 degrees.
Is it a routine practice to do the tile this way, shall I be worried about safety?
