The answer is: Yes! Roofing can be done in winter. Whether if you need to install a roof or to repair it, cold weather and snow shouldn’t stop you. There are lots of materials that don’t act differently during cold temperatures and have no issues with winter installation.
For example, metal roofs can be installed without any problems during winter time, since the quality is not compromised by cold weather.
BUT, if you need to install asphalt shingles in winter, make sure you do it right and don’t compromise the quality of the roof or warranty. You will have to pay attention to the products you use and change the application technique.
What happens to the asphalt shingles in cold weather
Asphalt shingles are not designed to waterproof the roof, they have the purpose of shedding water away down to the ground.
Asphalt shingles have a seal between them, designed to firmly bind and secure the shingles together when exposed to sun and warm temperatures.
So, if it is warm outside, after installation a seal will be activated, acting as an obstacle protecting the roof from any water, ice or snow going under the shingles.
Because of the cold temperatures, there is a high risk of that seal not to happen. This is the reason, why contractors and roofers need to make sure the seal is applied manually – a process named hand sealing.
Hand Sealing is a must
Hand sealing involves lifting up the asphalt shingles manually and applying a line of cement or a special adhesive using a caulking gun. Since this is a manual process, it will take more time to complete the job. Most of the time, more roofers are needed and it requires buying extra materials.
Read manufacturer instructions about hand sealing during cold temperatures. The majority of the manufacturers will advise you exactly the proper ways to hand seal. It is the ideal technique to make sure that the shingles will seal properly. Hand sealing will prevent shingles to be blown off by the wind and will make sure they’re perfectly bonded to avoid leaks or water damage.
Roofing in winter is more expensive
If you are a homeowner who needs a roof installation or repair in winter, expect to pay your contractor much more than in summer. There are numerous reasons why roofing during winter is more expensive.
First of all, it’s more dangerous for roofers. The risk of slipping or falling off the roof is much higher in winter since the surface of the roof is extremely slippery. All the crew needs to take extra safety measures and equip themselves with the latest security equipment: harnesses, fall protection systems, non-slip shoes, ropes, brackets and more.
Furthermore, as we said above roofing in winter requires more labor and more materials, so it is understandable that the price goes up a bit, usually up to 30%. Hiring more people and buying more materials are a must in order to get the job done properly.
Read the instructions carefully to prevent voiding your warranty
Most manufacturers specifically say in their terms what exactly they recommend for cold applications. Most of them, specifically mention that the shingles MUST be hand sealed during cold temperatures, or in sandy, dusty areas.
So, if you don’t follow the instructions and you decide to not handseal – if something bad happens you’ll lose the warranty.
What are the cold temperatures?
If you install when the weather shows temperatures below 40 degrees, then it is considered cold temperatures.
You Should Wear Proper Shoes with Anti-Slip Soles
During winter, the surface of the roof can get extremely slippery. You need shoes with added traction soles that can stick onto the roof and make you feel safe.
You need boots with rubber outsoles since rubber grips firmly on slippery and wet surfaces. That’s why the majority of the people working on decks, or on boats user full rubber footwear.
