Can You Get a New Roof or a Roof Repair in the Winter?

While you might think roof repairs and reroofs only take place during the warmer months, there are many reasons a homeowner may need work on their roof during colder times of the year. Sometimes, it's due to a sudden problem, such as damage from a severe storm, and other times what began as a minor area of concern suddenly escalates into a full-blown disaster just as winter strikes.

When that happens, homeowners can feel fortunate that professional roofing contractors can (and do!) work on roofs during cold and wintery conditions.

Common Cold Weather Roof Problems

Sometimes roof difficulties are directly related to the outside temperature and precipitation. And some regions of the country are known for their severe winter storms, like New England's Nor'easters and the blizzards across the Great Plains. Here are a few roof problems common to winter conditions. Homeowners can feel confident that professional roofing contractors can (and do!) work on roofs during cold and wintery conditions.

Ice Dams

When snow or ice melts on the rooftop, the water flows down into the gutters. But occasionally, brisk winds and cold temperatures cause this runoff to freeze along the eaves. When that happens, water begins to pool behind the ice dam, giving it a chance to infiltrate any tiny holes or cracks in the shingles. Using a quality synthetic underlayment and a specialty ice and water barrier can help prevent the formation of ice dams. Adequate attic insulation and proper ventilation can also help prevent ice dam formation by controlling the temperature of the indoor air directly beneath the roof's surface.

High Winds

Winds can take their toll on a home's roof. Wind-driven debris can damage shingles and the roof deck, while powerful gusts can even strip shingles right from the roof. Fortunately, Owens Corning offers warranties for their shingles against damage from various wind speeds through independent lab testing and proper installation. There are shingle options available, certified up to even 130 mph winds, to give you peace of mind.*

Excess Snow

Many parts of the United States receive yearly snowfalls in excess of 12 inches, and some New England states can average over 70 inches of snow. Besides adding considerable weight onto your roof deck, rooftop snow can help contribute to ice dams, leading to damage to your roof and gutters. Local building codes may call for specific roof framing systems, roof shapes and roof slopes to help combat excessive snow. Snow guards are also a frequent addition in regions with high winter precipitation rates.

Below Zero Temperatures

Sometimes winter snow isn't the problem at all; it's the accompanying chilly temperatures that can negatively affect your roof. When the outside air temperature drops into the teens and below, homeowners want to maximize their home's energy efficiency. Having the proper amount of insulation and the right kind can go a long way towards lowering winter heating bills. Adding more insulation is an easy way for attic spaces remain warm in the winter and cool in the summer. Use the Owens Corning insulation estimation calculator to see how your attic checks out.

Winter Weather Roof Work

While no one wants to be exposed on the roof during a blizzard, every winter season has its share of milder days. Many roofing contractors are experienced in dealing with the harsh winter climate, and they can adapt their workload accordingly.

Interior Work

Working in the attic and other interior spaces is relatively easy, winter or summer. Your roofing contractor can install insulation, check for leaks, and verify the roof's frame, all within your home. Other inside work includes sealing around vents and ensuring adequate ventilation.

Exterior Work

Should a storm or other event trigger an immediate problem with your roof's integrity, roofing contractors can place emergency tarps to cover damaged areas. Once the weather allows, the contractor can begin to make repairs. If the area that requires work is small, a tent can be placed on the roof temporarily to shield workers, if necessary.

If your roof is threatened by excessive snow or an ice dam, roofing professionals can also help with that. Always use a professional for any on-the-roof work, as improper snow removal can be damaging to the shingles, and can be dangerous to the workers as well.

Complete Reroofs in the Winter

It's possible to schedule a complete reroof in the winter if you're willing to wait for a stretch of good weather. Many contractors have flexible schedules during this time of year and are experienced with winter roofing techniques.

If you do choose to have your roof worked on in the winter, keep these things in mind:

• Your project may take longer, depending on the variability of the weather.
• You will need to designate a place to store the shingles that follows the manufacturer's recommendations.
• Shingles may take longer to thermal seal and may even need additional hand sealing.

SBS Modified Asphalt Shingles

Shingle manufacturers provide handling instructions that include optimum installation temperatures. SBS modified shingles, such as Owens Corning® TruDefinition® Duration FLEX® shingles, are more pliable, helping them resist splitting during less than favorable installation conditions. Duration FLEX® shingles also are durable, which may help them to withstand severe weather events. And, with Duration FLEX shingles meeting a Class 4 rating, they may qualify homeowners for an insurance discount.*
