Know your roof’s limit

The Glengarry News - - News -

Look up. North Glen­garry Town­ship is warn­ing that a snow-loaded roof can be fraught with trou­ble.

Some area farm­ers can ap­pre­ci­ate those cau­tion­ary words. In the last few weeks, at least two farm build­ings in North Glen­garry have been dam­aged be­cause of heavy snow loads.

Be­cause of heavy rain­fall, snow­fall and ice ac­cu­mu­la­tion, many prop­erty own­ers could be faced with a heavy ac­cu­mu­la­tion of snow and ice on their roofs.

Too much weight could put your build­ing at risk. Cracked walls, dif­fi­cult to open doors and win­dows and signs of wa­ter leak­age could all in­di­cate signs of po­ten­tial roof fail­ure.

The mu­nic­i­pal­ity notes that a res­i­dence ought to be able to sup­port a load of 20 pounds per square foot of roof space.

Roofs can tol­er­ate four inches of ice, 12 inches of packed snow or 40 inches of fresh snow.

Be­yond this depth, a home owner could be in the “dan­ger zone.”

PROB­LEM­ATIC PACK: Warm weather ought to take a load off many build­ings that have been cov­ered in lay­ers of ice and snow
