Thanks everyone for the kind comments.
Brian Yes, most of the roofs are tiles made from cement and are about an inch thick. There are some style variations. They can be red, black and I’ve also seen green. They have a matt top surface, but glazed tiles can also be purchased at a much higher price.
The glazed ones are best as moss and bird droppings cannot adhere to them, and the tiles stay in pristine condition throughout the years. We don’t have glazed, but I wish we did. I’m not going to use tiles on the grill shed because they would make it too to heavy to move when painting the house.
Moment No, I’ve never tried that. I can imagine it could be nice. The panel boards I’m using will be painted to match the house. The have rough texture on the outside which helps moisture to dry out, so a varnish wouldn’t work too well on that surface anyway.
