It is possible to install new roof materials over the existing layer, but this is not recommended. Any bumps or valleys that are in the existing material will show through the new material. In addition, by not removing the existing roof material, we are unable to inspect the roof deck for hidden damage. This may result in having to remove both layers of roofing should a problem surface later on.
