Roofing in winter conditions is a concern for many homeowners …”Will the roof properly seal?” …”Will the cold and snow/ice adversely affect the deck sheathing?” …”Will the caulking adhere to cold surfaces?” …these questions and other concerns are often expressed by Winter customers. Shingles can be properly installed in temperatures as low as –10 to –15 Celsius if the roof deck is cleared of snow/ice; if the temperature goes below –15, nails driven by an air gun will tend to damage the asphalt shingle, the glue in OSB Sheathing becomes ’super hard’ preventing airnails from ’seating’ properly and the fastening quality will become compromised (hand-nailing is recommended in –15 temperatures), and the asphalt becomes extremely difficult to properly form and cut
around vents, flashings, and roof protrusions.
Shingle sealant is designed to adequately seal up to one year after Installation, when the warmer temperatures begin to activate the process; but, until the roof seals, high wind force will cause lifting, and/or ‘blow-offs’ to occur— the repair costs will be covered by product manufacturers under their warranty, or by your homeowner’s insurance policy if you-do not have manufacturer ‘hurricane coverage’.
Roof sheathing is usually OSB, which has a high glue content which protects from moisture deterioration if shingled while wet (this type of sheathing will usually dry after roofs are shingled because there is still some air flow between the sheathing gaps). Caulking applied around vents, flashings, and roof protrusions will properly adhere during cold temperatures if the surfaces are clean and dry and if a winter grade caulk is used.
If proper care is taken, roofing in winter conditions is not a reasonable argument to be made against Winter Roofing — and there are a number of pluses to support having a roof replaced during the Winter:
1. A 10% (or greater) discount can be realized because companies want to keep their employees working during this slow season;
2. By year-end the roof will have a better seal because EVERY warm day of the year is working on those ‘self-sealing strips’ to create a superseal;
3. Companies will usually agree to a Springtime roof and clean-up inspection on any roof installed during Winter months, and all roof inspections are good;
If roofing in winter conditions is a concern for you contact good roofing experts to ensure you make the right decisions. When you have your roof done during the Winter months you’re not bothered during Spring or Summer with the mess and bother of doing home renovations Buildings are constructed ‘yearround’, and if Winter Roofing was a concern to builders, they would have a temporary roof covering installed — such as a Water and Ice membrane, and then the permanent roof covering installed in the Spring; but, that is just not the case.
