When to Remove Excess Snow From Your Roof

Before the winter starts, it's best to have a game plan for what to do when it looks like you have excess snow on your roof.  And, according to House Logic, "Calling in a professional to remove ice and snow from your roof is the smartest — and safest — option."

How to tell is you have too much snow on your roof?

The most important factor in whether or not you have too much snow on your roof it not how much appears to be on the roof, but how much that snow weighs, according to HouseLogic.

That’s because wet snow is considerably heavier than dry, fluffy snow. In fact, 6 inches of wet snow is equal to the weight of about 38 inches of dry snow.

The good news is that residential roofs are required by building codes to withstand the heaviest snows for that particular part of the country.

It's pretty easy to tell if it's wet or dry snow just by shoveling a bit of it in your driveway.  Wet snow will be much heavier by the shovelfull than dry snow.

You should also check your local weather forecasts. They should alert you if snow may be excessive.

How to tell if the snow should be removed

According to HouseLogic:

An indication that the accumulated snow load is becoming excessive is when doors on interior walls begin to stick. That signals there’s enough weight on the center structure of the house to distort the door frame.

Ignore doors on exterior walls but check interior doors leading to second-floor bedrooms, closets, and attics in the center of your home. Also, examine the drywall or plaster around the frames of these doors for visible cracks.

Homes that are most susceptible to roof cave-ins are those that underwent un-permitted renovations. The improper removal of interior load-bearing walls is often responsible for catastrophic roof collapses.

What to do if snow is excessive

According to HouseLogic, "Most home roofs aren’t readily accessible, making the job dangerous for do-it-yourselfers."

Calling a professional for snow removal is your best option.

Also, don't expect your roof to be completely snow-free after the contractor comes. According to HouseLogic:

Don’t expect (or demand) a bone-dry roof at job’s end. The goal is to remove “excessive” weight as opposed to all weight. Plus, any attempt to completely remove the bottom layer of ice will almost always result in irreparable damage to your roofing.
