Winter Roofing

Winter is best spent drinking hot chocolate and building snowmen, not roofing your house. If your home is starting to show signs of ageing and deterioration, here are three reasons why you should postpone your re-roofing until spring.

  • Asphalt shingles become more brittle when the temperature drops below 10 degrees centigrade. As such, bending, throwing, or dropping shingles during delivery and installation can break them, resulting in increased material costs.
  • Low temperatures will affect a shingles’ ability to form a proper seal. An experienced roofer will pay close attention to the temperature, humidity and sun exposure when re-roofing a home. They may choose not to re-roof if they believe the current conditions will affect a shingles’ ability to form a proper seal and compromise the roof's integrity.
  • Your warranty may not cover you. When shingles are not sealed for weeks or months, they are at risk of being blown off during windy seasons. Under such circumstances, the shingle manufacturer's standard limited wind warranty will not cover the cost to repair.

At Safe Roofing, we do not recommend winter roofing. If you have concerns regarding your roof's condition, your best option is to contact a professional roofing contractor and let them assess the roof condition before starting a project. Take advantage of the winter season to collect quotes and secure a spot and price with a trusted roofing contractor.

If you must re-roof your home, consider manually sealing the shingles with asphalt plastic cement. This process is time-consuming and may cost extra. Additionally, take the extra step in protecting your shingles by storing them in a warehouse rather than leaving them outside. Ask your roofing contractor if their supplier has stored the shingles in a warehouse, as exposure to fluctuating temperatures before installation may affect their performance.
