Yes, you can replace your roof in the winter.
Winter roof replacement will be slower and more expensive due to the challenges of the weather. Roofers might have to hand nail your shingles down to try and prevent the shingles from breaking. They might also have to use roofing cement to seal the shingles down (since they won’t seal properly in the cold). So in summary, you can replace your roof, just be prepared it is a trickier and more costly option.
Emergency winter roof replacement
Ice dams, icicles, heavy snow, and condensation can damage your roof throughout the winter. If you must replace your roof in the winter, talk to your roofing professionals about the roofing warranty and whether that will stay intact. If you don’t have a roofing emergency, it’s best to avoid replacing your roof in the winter.
Issues with winter roof replacement include:
Problems with thermal sealing
Most shingle manufacturers recommend installing shingles around 40 degrees Fahrenheit. This is because new shingles need multiple days of 40 degrees or warmer weather for proper thermal sealing.
Issues with shingle installation
Fiberglass shingles can crack when being nailed down.
Some shingles need to be cut around your chimney, vents, and other roof accessories. As you can imagine, it can be hard to cut these shingles in cold temperatures.
It’s best to wait until the spring when temperatures are above 50 degrees. Early spring is a great time to replace your roof. The end of summer and fall are typically the busiest time of the year for roofing companies.
