It appears the snow has departed the Barrington area for at least a day. The long term forecast shows a few days of light snow on Saturday, Sunday and Wednesday and after that the temperatures will rise into the high 20’s. Total amounts with winter storm Hercules and the lake effect snow we had on January 2nd are about 15 inches in our neighborhoods. So how much snow is too much snow for your roof?
Snow is either light and fluffy or wet and heavy. Heavy snow can be dangerous on roofs, especially if your pitch is shallow. Shallow roof pitches are more common in older homes, especially ranches. As our snow was light and fluffy I think our roofs are safe for now. The last time I had to remove snow from our house was when we lived in Deer Park and we had about 24 inches of heavy wet snow.
Mother nature may have some tough winds ahead and darn cold wind chills but there’s always a silver lining to wind. With light and fluffy snow on your roof and wind in the forecast, you can bet a lot of your snow is going to blow off the roof and end up somewhere on the ground.
What if you don’t have any snow on your roof? That means the heat you are paying for inside is rising through the attic, heating the roof and melting the snow. If that’s happening you have an insulation crisis. Actually your attic must be void of insulation or have so little it’s not at all effective. Time to get someone in to lay new insulation, you’ll be pleasantly surprised at the lower heating bill. Don’t wait, do it today!
Icicles. Very pretty no doubt but these can also damage your roof. As snow melts the icicles form. It’s not the icicles that matter, except maybe to passers by walking under them. It’s more that once formed, melting snow can travel backward underneath your roof coverings and cause damage. Many new roofs have an ice barrier which prevents the damage but it’s a good idea to knock of your big icicles.
