Snow On Roofs A "Concern"

It's a winter to remember for some homeowners.  Many have huge amounts of snow on the roofs of their houses which is cause for concern according to Ron Rost of Triad Roofing.   His advice is to use common sense and examine how much snow has accumulated and to act before a possible collapse.   Rost says the problem is more serious in some parts of the city.  He says his company has been answering up to 20 calls a day for snow removal services.
