Question about snow build up on my roof?

Terry, I have a question for you. When your bungalow was built, Was there a 'building permit' issued? If there was then the blueprints for it had to be looked at by your local building/zoning dept. which then had to p all weight(snow,ice,live) barring loads on the roof. If there wasn`t a building permit issued and ped for 'occupancy' then there might be a problem here. Even still I would try to shovel off some snow, just around all the pipes sticking up through the roof shingles an off of the top of the chimney(if you have one). This will keep any harmful fumes from coming back down into you house. Don`t recommend hiring someone to shovel due your insurance company issues here-(getting sued by falling off roof).Don`t know if your bungalow has rafters or trusses. Either way, your local building dept. inspector would be the best person to talk to here. 4 to 5 feet of snow is a lot of snow even on a roof, it will only get worse when it turns to solid ice-(more weight). Hoped this take a little weight off your shoulders and your roof... Good Luck an keep warm.
