Our customer at Heathrow had experienced many years of water ingress from glazed lights that were cast into the flat concrete roof deck.
Numerous attempts had been made over the years to seal around the rooflights using a variety of mastic material, however these repairs were rarely successful.
The client was keen to maintain natural daylight provided by the rooflights, therefore covering them over using roofing felt was not an option.
RoofTech were contacted and we installed new clear polycarbonate domes over the failing glazed rooflights complete with ventilated kerb details to disperse any trapped moisture.
The new dome rooflights and surrounding flat roof are was then weathered using two layers of high performance bitumen based roofing felt.
The works were completed within timescale and budget.
