SNOW ON ROOFS– some roofs can handle more snow than others. In New England, roofs should be designed to hold between 40 and 70 pounds per square foot. The total accumulated weight of two to four feet of snow could be as high as 60 pounds per square foot! If there is ice, it is much heavier – one inch of ice equals a foot of snow. You should not climb on your roof to remove snow – rather, use a snow rake while standing at ground level, or have it professionally removed.
