Roofing Systems

ALT roofing and waterproofing membranes are seamless, cold applied, flexible reinforced, UV, chemical and root resistant MMA membranes for flat or inclined decks. They are the ideal solution for most every substrate including modified bitumen, asphalt built up roof (BUR), concrete, wood, steel, zinc, lead, copper and plastics. Single coat application makes our membranes cost effective, especially for large projects. ALT roofing systems include various roof assemblies such as insulated roofs, inverted roof membranes (IRMA), recovery, flashing only, protected roof membrane, green roofs, built up roof (BUR), recovery and direct to deck.
