It is not a common practice to replace a roof in cold winter months but if it is needed “yes”. If there is a major issue with your roof and did not have the budget to get it done last fall, better now than before the heavy rain begins in spring.
Shingles do freeze in winter but if its kept in a worn place prior to installation, it will make a big difference. I remember re-roofing a house in december and had all the material boomed on the roof. When we started to install and couldn’t separate the sheets apart because of the cold temperature tought me a lot about replacing roofs in winter. There are lots of details that needs to be taken to a consideration when replacing a roof in winter. For example if the pressure is too high when using an air roofing gun, it will puncture the shingle and next time there is a wind storm your roof will be waving like the ocean. It is very important to have the right pressure, just enough for the nails to be flush with the surface of the shingles. Also all the ice and water shield should be heated just enough to bound to the plywood. Caulking should be applied warm on all the exposed nails and around the vents. Cold caulking does not have the stickiness to actually seal properly. Keep caulking warm in the truck prior to applying to get better results. Before the heavy rain fall your roof should be inspected for proper bondage.
