A properly designed snow country roof “manages” the departure of the snow from your roof. While getting snow off the roof quickly is desirable, roof avalanches can be dangerous. They can rip off roofing material, gutters, take out landscaping below, threaten passersby, and block entries. Snow retention devices hold snow on the roof until its removal can be controlled. Summit Roofing uses everything from small snow clips to larger snow fences depending on the location of the home, pitch and type of roof.
