We are about to start building a modular home in upstate New York in an area that gets 76" of average snowfall per year (Buffalo, New York, by comparison gets 82" of average snowfall per year). A 6:12 pitch shingle roof comes standard with the house. While driving around the area this weekend, I couldn't help but notice that many of the houses we saw had ice dams on their roofs, icicles hanging over the edges and broken gutters in some cases. I hear about people using ladders to climb up on the roof to break up ice or shovel snow. I also hear about people using snow rakes to clear off the edges of their roofs. What pitch roof should you install and what material should it be made of so you can stay in during the winter without the roof leaking, collapsing, etc. ? How do you find out what the codes/rules/ordinances/regulations are for your town/county ? Thanks for your help and advice in advance.
