Building or renovating a home on a hill in a snowy region? The single most important design decision you'll make isn't the paint color or the porch — it's the roof slope. Get it right, and your roof sheds snow safely for decades. Get it wrong, and you risk leaks, ice dams, and even structural collapse.
