Liquid Applied Roofing Systems

Our liquid-applied systems provide seamless waterproof membranes that are easily applied and conform to any penetration shape. This is ideal when faced with a confined urban space, numerous roof penetrations or restricted use of hot asphalt or heat welding.

For roofs where standing water is a problem, our JM PMMA Liquid Membrane System forms an exceptional bond, creates an elastomeric, highly protective surface and delivers exceptional waterproofing performance.
