In Buffalo, the large ice dams on homes this winter are causing roof leaks. This does not mean that your roof needs to be fixed or replaced. Ice dams at the roof’s edge cause melting snow to back-up under your shingles. In most cases, when the ice dams are gone the leaks will not return.
If you have ice dam leaks don’t replace your roof.
Adding ventilation is not the answer either this only pulls more heat out of the house and not only adds to the problem it drives up energy cost due to the fact that it is releasing the heat through the roof and the furnace kicks on more to replace what has left the house. To prevent this you need to air-seal and insulate your attic. The roof deck must be cold to stop snow melt. A warm roof melts the snow, the water runs down and re-freezes at the overhang causing an ice dam to form, and subsequent leaks. A lack of insulation and propper air sealing is the direct cause to a warm roof deck and melting snow. Most people call a roofing contractor when they are experiencing an ice dam leak. The roofing contractor will remove the ice and shovel snow off the roof. This will temporarily stop the leak but it will not stop the ice dams and leaks from happening again after it snows again. The roofing contractor may then suggest that your roof needs replaced. Most of the time this is not true! if the roof doesn’t leak when it rains you don’t need it replaced. We have been in several homes and talked to several home owners and several have signed new roof contracts but the roofing companies have not suggested a way to stop it from happening again!! And to top it off the roof is fine! Bottom line is call a good insulation contractor that will air seal and insulate the attic FIRST!
