It’s almost that time of the year again, where the temperature starts falling and so does the fluffy snow. Snow and Ice can be very heavy, with ice weighing up to 57 pounds per square foot, and snow can weigh up to 21 pounds per square foot if it’s wet heavy snow. A flat roof is more susceptible to downfall, more flat roofs will collapse with 1-2 foot of snow on it. Drainage maintenance is very important for a flat roof, if the drainage were to freeze or clog snow would need to be removed by hand as if it melts and sits on the roof it can add unwanted weight causing the roof to then collapse.

Sloped roofs can disperse weight so that all the stress isn’t on the one part of the roof and the water tends to run off the roof into gutters. The steeper the slope, the more weight the roof can sustain. There are many reasons your roof could collapse, such as poor design, lack of maintenance, structures built prior to building code requirements, or all the above.

Weathershield Roofing recommends you get your roof inspected twice a year to ensure your roof is able to sustain the next thing that life might throw at it.
