Installing a Modified Bitumen 2 Ply Torch Down Rubber Membrane over an existing Tar and Gravel is the most cost-effective way to replace a flat roof. There is no need to remove the existing roof because the fiberglass is anchored to it and performs as a barrier between the 2 ply rubber membrane that is placed over it and fused together with a torch.
Installing a Torch Down Rubber roof over tar and gravel will:
1. Save the expense of tear down and hauling away of the old roof
2. Save on labor cost
3. Save on material cost
4. Provide an added insulation
