Q: I have downspouts on the north side of my house. After a few sunny days some snow melts but the spouting isn't melted and the water overflows and drips directly over the door, which is about 10 feet from the downspout. Even if the attic were properly vented and insulated to prevent ice damming, could there still be a problem when the heat from the sun warms the roof to melt the snow but the spouting is still frozen enough to not allow the flow of water to the downspout?
There is no access to any crawl space, so what would be the best alternatives to checking the situation out?
Also, there are no visible signs of vents anyplace on the building. This is a three-unit townhouse, built in 1977, and the only place it drips is the end unit
