Proper performance from shingles installed and used in cold weather can be achieved by following the recommendations listed below:
Make sure that the roof is properly ventilated.
Be careful when using shingles in cold weather. They tend to get brittle and may crack or break. Try not to throw, drop or bend shingles.
If you are in an area that experiences freezing winter temperatures, eaves protection should be used to reduce water damage from ice dam formation. Use self-adhering eave protector membranes.
Hand seal asphalt roof shingles in cold weather with an asphaltic cement recommended by the manufacturer.
When applying ridge caps, keep the shingles that are being used as ridge caps in a warm place so that they will be flexible enough to bend.
When re-covering an existing roof with new shingles, make sure that the old shingles are flat.
In areas that receive high amounts of snowfall, try not to damage shingles when removing snow. Damage caused by snow removal is not covered under our limited material warranty.
Use caution if walking on a roof in the winter time. The sealant bond between shingles can become quite brittle in cold weather. Therefore, traffic on the roof may cause sealant bonds to break.
