Snow and cold weather damage to flat roofs in Oxfordshire

With the sudden change in weather i have had lot’s of enquiries about leaking flat roofs. The cold weather, snow and ice have caused the felt to start cracking more and with the rain the ingress of water starts. I have sheeted over some roofs as a temporary measure before I can replace it with a new system. Early signs of leakage should be detected and dealt with before the weather takes hold and damage escalates.
