One of the most damaging effects of cold weather on roofs in Wisconsin is ice damming. When snow accumulates on your roof, heat from your home melts it from below. The water then refreezes at the colder eaves, forming ice dams. This blocks drainage, causing water to back up under shingles and leak into your attic or walls.
In areas like Oconomowoc, where temperatures often dip below freezing, ice dams lead to interior water damage, mold growth, and structural weakening. To prevent this, ensure proper attic insulation and ventilation. Windlickers Exteriors recommends professional inspections to identify vulnerabilities before winter hits.
Snow Load and Structural Strain
Heavy snowfall is a hallmark of Wisconsin winters, and the weight can exceed 20 pounds per square foot which is enough to stress even sturdy roofs. Flat or low-pitched roofs are especially at risk of sagging or collapse under accumulated snow.
Roofing materials like asphalt shingles may crack or shift under the pressure, compromising waterproofing. Our team at Windlickers has handled numerous emergency repairs from snow overload in Waukesha County. Regular snow removal with safe tools and reinforcing older roofs can mitigate risks. Always consult experts like us for assessments tailored to Wisconsin’s climate.
Thermal Shock and Material Degradation
Rapid temperature fluctuations which are always common in Wisconsin’s unpredictable weather, cause thermal shock. Roofs expand in mild spells and contract in deep freezes, leading to cracks in shingles, flashing, or seals. Over time, this accelerates wear, especially on aging roofs.
Metal roofs, popular for their durability, can still suffer from condensation buildup in poorly ventilated spaces, promoting rust. Siding and gutters aren’t immune either; ice expansion can crack gutters, pulling them away from the roofline. At Windlickers Exteriors, we specialize in durable materials suited for cold climates, ensuring long-term protection.
Wind and Freeze-Thaw Cycles
Strong winds combined with freezing conditions lift loose shingles or blow snow into crevices, where it melts and refreezes, prying materials apart. Freeze-thaw cycles increase the intensity of this, turning minor issues into major leaks.
Homeowners in Southeast Wisconsin should watch for granule loss on shingles which is a sign of weathering. Proper installation and maintenance are key; our affordable roofing services include wind-resistant options to combat these elements.
