Why is there ice on my roof?
Hanging icicles and ice buildup on your roof is something that should be taken very seriously. Not only does the ice weigh 5 times as much as snow on the roof per sq inch, but it can also be a sign of bigger issues inside the roof. Snow only melts on its own for two reasons: the warmth of the sun or heat escaping from the home. In both cases the water will fall to the lowest point on the roof and, in most cases, during the winter it will freeze as icicles and create ice dams. The refreezing of water has a damming effect creating an even bigger ice dam behind it. Continuous feeding of the ice dam by melting and refreezing snowmelt can cause significant damage to the roof and well damage to the interior of your home.

How much snow does it take for an ice dam to form?
An ice dam only needs a tiny bit of snow to form on your roof. An ice dam can form with as little as an inch of snow (or even less). We’ve seen ice dams form when there’s no visible snow on any major part of the roof. Why? Because Old Man Winter loves to pile snow in the spots you can’t see from the ground – especially drifted snow in roof valleys and areas where your roof meets an exterior wall. Eventually those drifts can melt, trickle down, hit the overhangs and/or valleys, and slowly form an ice dam.
Why is a flat roof more susceptible to collapse than a sloped roof?
A flat roof is often times more susceptible to collapse than a sloped roof, simply because a sloped roof disperses weight whereas a flat roof cannot. Generally, the steeper your roof angle the more snow it can hold (e.g. a 10/12 or 12/12 pitch roof handles more snow than a flat roof).

In either of those cases, you might want to remove the snow even when there’s only a foot or so up there.
