You should take a good look at the endurance of your rafters and purlins. Because this tile is heavy, and the width of this tile is not the same as that of the small blue tile, you need to rearrange your rafters so that they are just opposite to the fixing holes of the colored tiles. This kind of tile is usually fixed with long steel nails. You must use thicker battens for your roof rafters. On the one hand, it is to carry. On the one hand, it is also to fix the tiles. Because this kind of tile is the fixing hole of the upper piece and the lower piece, nothing else can be seen on the roof, unlike the previous tiles that need to be fixed with bricks or lime. Will be more beautiful. I hope it helps you.
