They are made of a seamless rubber that can be customized to your roof in a wide variety of widths to create a waterproof seal.

Hot Tar Roofs

Hot tar is a time-tested commercial building material, used throughout the U.S. for nearly 100 years, that is both long-lasting and cost-effective. This is comprised of a multi-ply system in which multiple layers of fiberglass-based asphalt are laid on top of each other with reinforcing plies to create a completely waterproof membrane.

Torch Down Roofs

Sometimes referred to as Modified Bitumen, torch down roofs are similar to hot tar roofs. They are made up of an activated heat membrane (comprised of rubber asphalt) that creates a waterproof seal. Torch down roofs are very low maintenance and highly durable against all types of heat and wear over time.
