Guaranteed Asphalt: all under one roof

The UK’s sole manufacturer/installers of hot melt monolithic membranes

Since the early 1980s, Guaranteed Asphalt has manufactured and supplied the industry with mastic asphalt. We then developed our own polymer modified brand, GuaraFLEX. It is with this proud heritage and knowledge that we have developed a new fully-bonded hot melt system, GuaraTEC.

GuaraTEC monolithic roofing system is a one part, hot melt, self-healing membrane. Manufactured from a blend of polymer-modified bitumen, natural rubber and ultra-light fillers, the membrane is reinforced with a high tensile heat-resistant polyester fabric to provide exceptional strength and flexibility as well as giving excellent adhesion to almost any substrate.

All contractors are trained at our offices in London or Northamptonshire and undergo rigorous practical training followed by a written theoretical examination to prove aptitude. Our own operatives have undergone a minimum four-year roofing apprenticeships and are already experienced in other forms of waterproofing such as mastic asphalting and felting.
