Roofs
Roofs are the first defence in the waterproofing of any building. They take the full force of torrential downpours of rain in severe rainstorms and should also provide protection from wind driven rain.

Consequently the detailing of flashings, penetrations and guttering is very important.

Sometimes adverse weather conditions can penetrate past acceptable detailing or cause details to fail.

Roofs also bare the full brunt of the elements causing over time the deterioration of waterproofing materials, allowing water to then enter the roof cavity.

Common problems:

  • Internal gutters leaking
  • Skylights leaking
  • Broken roof tiles
  • Long run roofing iron detail incorrect
  • Torch on membranes detail failing
  • Liquid and sheet membranes punctured
  • Corrosion of metal roofing materials
  • Flashings failing in severe conditions

Solutions can involve:

  • Application of liquid and sheet applied membranes
  • Replacement of corroded flashings
  • Modification of existing detailing
