Is it worth saving? There had to be a reason that they sprayed to coating over it. Is it dry and cracked? did you try a power washer? good luck with that one. | ||

Hello, We're trying to remove a bitumen coating from a 8500m2 slate roof. We're trying to find a method of cleaning the tiles so we can sell them on or use them. There's about 3-5mm of bitumen. We took a sample tile and coated it in a soy based solvent, which cracked it, and the we let it soak in a "heavy duty" Cleaner overnight. And a pressure washer did the rest. Although this worked, its a lengthy process for 1 tile, and we have an entire roof to do. If anyone has ideas, or experience in this sort of cleaning help would be appreciated. Thanks. |
