Shovel off the stinking roof!!!!!!!
We had to do it a few times every winter in NYS because of lake effect. That’s a lot or weight and they are asking for trouble by not addressing it.
Much of my roof in SE Idaho has a very steep pitch. Local building codes require a roof that can support 65 lbs per square foot to accommodate snow load. The part of my roof that doesn't have a very steep pitch is 32 feet above ground level. Getting up there to shove snow off is dangerous in warm, dry weather. Attempting it with deep snow and ice is begging for a trip to the hospital.
By comparison, my parents home in Chula Vista had pretty easy roof access. I could climb up on the 6 ft high gate in the side yard and step up onto the roof. I spent many hours up there painting the trim at the roof line at age 10.
Easier said than done.
