The biggest concern many have about winter re-roofs is improper sealing. There is a strip on the back of each shingle that heats up when warmed by the sun to cause the shingle to seal to one below it. This prevents wind blow off. If the shingle does not reach adequate temperature then they will not seal properly. What many people do not consider however is that a roof is on average 20 degrees warmer on the roof. If its 50 degrees outside it can be 70 degrees on the roof. In addition all of the warm air from your home is blowing up into the attic and warming the underside of the shingles as well which aides the sealant with proper adhesion.
If its just to cold out and an ideal temperature cannot be reached to get the sealant to warm up and adhere hand tabbing is suggested. Roofing cement is an asphalt based products that can be purchased in a caulking tube. By distributing a few quarter size dabs on the corners of the shingles you can easily achieve the necessary seal and wind resistance requirements until the temperatures warm up to seal the shingles.
