Roof Rescue specialise in the application of rigid Polyurethane foam both in the UK and France. Applied internally to the underside of your damaged or leaking roof the spray foam hardens to form a permanent water proof seal. Not only that, the application will actually bond thousands of individual tiles or slates into a single structure of far greater strength as well as reducing heat loss by an incredible 30%. Furthermore, all of this can usually be achieved for just half the cost of roof replacement. Areas serviced: East Cornwallwww.roof-rescue.co.ukTrent Cottage Petherwin Gate, PL15 8LW
