We install and repair EPDM rubber, GRP fibreglass and torch-on felt systems on extensions, dormers, garages and bay windows.

Correct falls, sound decking and clean edge detailing mean a flat roof that sheds water properly.

Signs you may need this

  • Standing water (ponding) after rain
  • Blisters, cracks or splits in the felt
  • Soft or spongy decking underfoot
  • Damp inside below the flat roof
