Can these be used on a roof in NY? Our drains get clogged with debris all the time; we want to cover up the area to prevent this from happening, and to keep the drains open. Will they be ok in extreme wheater?

Our Vented Grid-Loc Tiles are not rubber roof approved, but they can be used as flooring on a rooftop. These tiles are UV stable and would be able to withstand the elements well. Since they are vented, they would allow your roof to drain properly. If you do have a rubber roof and are afraid it will get damaged, we recommend placing plywood down under the tiles to protect the rubber membrane below.
