Abstract: A reinforcement membrane for reinforcing a roofing membrane has first and second layers including a fiberglass mat and a scrim of low-shrinkage organic fibers; a third layer comprising nonwoven low-shrinkage organic fibers providing an added mass of the low-shrinkage organic fibers for possessing latent shrinkage while the reinforcement membrane is in tension, which latent shrinkage is released in the absence of tension thereon during a temperature increase within a range of about 10C to about 30C; and a membrane coating material bonds together the three layers in tension, without completely filling interstices among the respective fibers of the three layers, wherein the interstices are adapted to be filled with a bituminous roofing composition.
