Wondering if the price tag is really the point here. A $75 saw paying for itself twice over just means you did two jobs with it, which any $20 hardware store saw would also do. The real question is whether that fancy blade actually saves you time on a normal day, not one weird backyard job where nothing else fit. Sounds like you talked yourself into liking it after the fact. A tool that costs that much should be surprising you every single week, not once a month.

Read a trip report saying Eliot Creek stays snowy into late July most years, so your uncle nailed it.

Ran into the same thing at my old place, that lip on the shingles was pushing the hangers down just enough to work them loose every freeze. Bumping them up so they sit on top instead of tucked under fixed it for me too, haven't touched them since.
