Silver Spring Roofing: Article About Roof and Snow Concerns
Cold weather poses unique challenges to rooftops, especially when snow is involved. From weight concerns to possible water leaks into the home, snow affects the roof in several different ways. A Silver Spring roofing professional can help homeowners understand these challenges and how to keep the roof as structurally sound as possible through consistent preventive maintenance appointments.
Flat or low-slope roofs are often used in conjunction with standard roof slopes to create a stylized architectural appearance. However, flat rooftops are perfect locations for snow accumulation. Snow cannot slide and fall off to the ground because of the flat surface it resides on. Although most normal snowfall doesn't damage a rooftop, a big storm with excess precipitation amounts can add too much debris to the roof's surface. Contractors may need to remove the accumulated snow and reduce weight strain on the home's flat rooftop.
Some homeowners are turning to metal roofs as durable alternatives to traditional shingle installations. Metal is incredibly strong, but it reacts to cold weather much differently than other roofing materials. As the roof warms after a storm, snow doesn't just melt in place. It actually slides off the roof in large chunks.

Porches and landscaping are often damaged from these released snow drifts. Homeowners must have roof snow guards installed by a professional to prevent these miniature avalanches on the property.
Even in the coldest regions, proper roof ventilation is essential to the entire structure. When snow accumulates on a roof, it might melt slightly if the roof has too much trapped hot air within the attic. As the snow slides down the roof, it freezes again at the eaves. This process is referred to as ice damming. Any snow, rain or other precipitation pools at this roof edge, creating possible water leaks into the home. Contractors can add or adjust ventilation into the attic to reduce temperature differences at the roof surface. Air moving through the attic at a constant rate reduces the risk of snow melting and reforming across the entire structure.
Each roof is distinctly different when it comes to its reaction to cold and snowy conditions. Before winter arrives, homeowners should hire a contractor to survey the roof for any weak points. From poor ridge vent ventilation to lifted shingles, contractors can fix all the rooftop issues before snowy conditions arrive. The home's interior won't be vulnerable to water damage with proper roof care in the spring, summer and fall.
