Relevant observation 2
Last winter at the height of ice-dam season I tried to observe patterns in ice-dam formation. I couldn't find any clear correlation.
All the houses of this species have formed 5" high ice dams. No other houses have visible dams. Remarkably sharp correlation.
Also unlike last year, I'm not seeing a growing trend of raking. It's just me and the other predictable regular. Not coincidentally, the other regular raker is one of the abovementioned OEM owners, and not coincidentally his house is the only exception to the abovementioned rule. 
I started with hypotheses that steep roofs should be better and newer houses should be better. Nope. Shape and age are IRRELEVANT. Even the steepest roofs and the newest houses can form ice dams. Some metal roofs have icicles, but on a metal roof it doesn't matter because there's no way for the water to force its way through the membrane.This year (almost the same date!) the pattern is far more distinct. My morning walk includes a dozen houses of this species. Nice late-50s ranchers, well maintained, often still occupied by OEM owner.
