Make sure that any roof repairs, cleaning or replacement work isn't put off and is carried out by a qualified roofing contractor. Pay particular attention to roof tiles that may be damaged in bad weather and make sure that you stop heat escaping by installing roof insulation. Whether you have a timber or metal roof structure or need your flat roof waterproofed, a roofing contractor can help. You also need to regularly inspect and clean your guttering; brickwork and stonemasonry also need specialist attention. If you need to carry out demolition work then contact a company trained in this field.
