How And When To Remove Snow From Your Roof


To avoid costly roof repairs, Cambridge homeowners need to understand when snow has to be removed, when it is safe to do it on their own, and when to call for professional help. Up to a certain point, having some snow on your roof can be beneficial; it acts as an extra layer of insulation against the frigid outdoor conditions, and it can give your home that peaceful “winter hush” because it also insulates against sound. Having too much snow on your roof is a problem, though, because of the additional weight, and because it can slide off and injure people or destroy property.

Some Snow Considerations

  • Density Of Snow – Wet snow weighs considerably more than fluffy, dry snow. If the snowfall in your area has been wetter, you will need to deal with snow accumulation on the roof sooner and more frequently than you would with drier snow.
  • Look Before You Shovel – Before you remove any snow, walk around your house and look for melted spots on the roof: Low points in the snow blanket or voids. These are places where it is likely your attic insulation is not doing its job. Take note of these places and have them investigated and repaired as soon as possible.
  • How Much Is Too Much? – Ultimately, the determining factor is how much snow your roof can take is weight. But since you don’t want to wait until your home is exhibiting warning signs to remove the snow, it’s a good rule of thumb to allow no more than six inches of snow to accumulate on your roof.
  • Warning Signs – You home will warn you when there is too much weight on the roof. Again, you should, ideally, deal with snow before it reaches this point, but it is important to note that these signs are serious, and you should not delay in removing snow from your roof if you experience them. Signs include interior doors sticking shut or popping open; more than usual “house settling” sounds like pops, cracks, or creaks; sagging ceilings; or sudden water leaks. These can be signs of an impending roof collapse, so if it is not possible to get the snow off the roof immediately, it may be wise to stay somewhere else until the roof is relieved of its extra load.
  • DIY Or Call In The Pros?– If you are a hardy do-it-yourselfer, you can probably do a good job of removing the excess snow from a one-storey home on your own, if you are careful and have telescoping snow rake. Be sure to leave an inch or two of snow for insulation. If you are less confident in tackling a ton of snow, or you have a multi-storey, it is time to call for help! Be sure you hire a licensed and insured roofer, because snow removal can be dangerous, and you don’t want to be liable for injuries or damages caused by unlicensed workers.
