Addressing Winter Roof Damage – The Roofing Center

Winter, with its freezing temperatures and heavy snowfall, can be particularly harsh on roofs. As the first line of defense against the elements, roofs are prone to various types of damage during this season. Here, we delve into the most common winter roof damages and how to address them effectively.

The Menace of Ice Dams

Ice dams are notorious for causing shingle damage during the colder months. They form when the roof’s main surface warms up, causing the snow to melt. As this meltwater flows down to the colder eaves, it refreezes, leading to the formation of an ice dam. Over time, the dam prevents snowmelt from draining through the gutters. This water can then seep underneath the roof shingles and freeze, causing the shingles to lift or get damaged.

Such damage makes the roof vulnerable to leaks. When water from melting snow or rain infiltrates these gaps in the shingles, it can lead to rotting of the roof decking. This can also result in mold growth and moisture damage in the attic and ceiling areas.

Solution: Sealing attic air leaks and replacing damaged shingles are effective remedies. Additionally, installing ice and water shields along the roof’s eaves can deter the formation of ice dams.

Structural Decking Woes

Roof decking provides the essential structural support to the roof. Typically made of oriented strand board or plywood, it needs to be robust enough to bear the weight of the shingles. 

However, during winter, heavy snow loads can strain the decking. A roof that adheres to building codes should be able to support up to 30 pounds per square foot of roof surface. Excessive snow, especially packed snow about two feet thick, can be too much for an average deck to handle, leading to breakage.

Solution: Regularly monitoring and removing excessive snow can prevent such damage. Additionally, roofs with slopes, like hip and gable roofs, are better equipped to handle snow as it can easily slide off.

The Deceptive Attic Condensation

Attic condensation can often be mistaken for a roof leak. During winter, as warm air from household activities rises to the attic, it meets the cold underside of the roof deck. This interaction leads to condensation, similar to how a cold beverage “sweats” during summer. Over time, this can result in mold growth, moisture damage, and even compromise the structural integrity of the roof.

Solution: Ensuring proper attic ventilation is crucial. All vents should be clear and functional. Moreover, inspecting and replacing old or damp attic insulation can prevent warm air from entering the attic, thus preventing condensation.

Flashing Failures

Roof flashing, made of thin metal strips, is crucial for directing water away from the roof. However, during winter, these strips can contract due to temperature drops, creating gaps for moisture to seep in. Additionally, ice accumulation can bend the flashing, further compromising its function.

Solution: Regular inspections, especially during winter, can help in early detection of flashing damage. Replacing faulty flashing can effectively resolve the issue.

Unwanted Critter Guests

As the temperature drops, roofs become attractive nesting spots for animals like mice, squirrels, and birds. These critters can cause significant damage by using insulation materials for their nests or gnawing on electrical wiring.

Solution: Regular attic inspections for signs of animal activity, like droppings, can be beneficial. If any signs are detected, it’s essential to contact pest control professionals.
