At the building permit stage the lumber yard supplying the structural components creates the truss and floor layouts. They do this on a proprietary software that produces considerable detail. I attempt to review each page in order to get a greater understanding of what I am commiting to buying and building. The renderings sure help a lot!
These are the roof layout rendering of my upcoming project. This is very appealing to me because I like simple roof lines that drain well and are predicable and easy to shingle. Most of all I want the roof cavity to have clear and obvious ventilate pathways that won't collect frost in the winter during a heavy snow year. This roof passes all of my criteria. What we have seen, especially last winter, is many roof failures from ice jammed valleys and snow blocked vents. Those are a nightmare to deal with.
