That was one of the many things that occurred to my worry-wart mind... Sometimes that *is* a good thing, since you can prevent so many future problems that way...
Another thing that flitted through -- would the lubricant destroy the asphalt shingles as it gets rained off? If I spray as little as necessary, it seems like it shouldn't be a problem...?
And yes, I'm still afraid of cutting a hole in the roof. But there are already plenty of holes for vents, and there are plenty of substances that will seal the rain out...
Any roof I ever put on will be light-colored metal, but these asphalt shingles aren't ready to be replaced yet.
Another thing -- I went to the big box store and looked at the turbines they have. OMG. I would not buy one of those. I might not put it on my roof if they gave me one. Flimsy aluminum, "internal bracing" that obviously won't stand up to much wind, and when I spun it, I could feel a womply place in the spin. Those bearings won't be lasting very long.
This one I got at the ReStore is very sturdy galvanized metal, has very sturdy exterior bracing, and even after sitting outside waiting for me for a couple of years, its rotation is silky-smooth and totally silent. I don't see a brand-name on it anywhere, but if I put a second one on my roof, it will be one like this.
