  • Patent number: 6023906
    Abstract: This invention is a method for sealing pitched shingled roofs. The object is to minimize the cost associated with sealing a roof against standing water such as the case with an ice dam. The method involves placing a continuous waterproof membrane over existing roofing shingles and placing the new shingles on the membrane. The membrane is self adhesive on one side, which is used to adhere to the existing shingles. It is further durable enough to withstand the forces between layers of shingles and thin enough so not to present torque problems with the fasteners used to affix the new shingles to the roof substrate.
