What is Smartseal?

Smartseal uses a flat roofing system which is based on glass-reinforced plastic, more commonly
known as GRP.

Benefits of Smartseal

Traditional bitumen flat roofs are often seen as problematic and prone to damp or leaks, but the Smartseal roofing systems can prevent these problems, thanks to their unique properties, as follows:

  • lightweight but durable – our Smartseal systems won’t damage the structural integrity of your building
  • totally seamless – meaning the traditional weak points of bitumen roofs, such as joins and corners, are avoided
  • choice of colours – meaning your roof can match your home or premises perfectly
  • not affected by extremes of weather – unlike bitumen, it doesn’t expand or bubble in the heat of summer, or contract and crack in the cold of winter
  • fire-retardant
  • completely UV-resistant
  • suitable for use on all kinds of buildings, from historic houses to new builds, and for architecturally challenging or conceptual building projects.

C100 replaces traditional lead flashings and comes with or without an integral moisture trap.

D260 is for application with abutting walls and gutter linings. It ‘floats’ unattached beneath the c100 to allow for expansion of the substrate. It also provides cross-roof ventilation.

F300 is flat sheeting used for continuous flashing under slate at the junction with the roof as shown in the example. It can be used for gutter lining, cavity trays etc.
