We’ve all seen them, right?
You look up, waaaaay up, and see these spear-like threatening (yet somehow beautiful) icicles hanging down. Just waiting. To either:
a) drip slowly down and tickle your neck
b) crash and shatter and scare the bejeezus out of you
Well if they’re hanging from your roof, it could be a sign of insulation issues.
According to Greg Furlong, an energy analyst with EnviroCentre, large icicles means you have a hot roof. Attics should be cold in winter…if your attic is cold and your roof is good, snow will pile up but it won’t melt. But if you have a warm roof, the snow will melt and then freeze when it hits the cold eaves. (enter icicles)
Some suggestions if your house has large icicles:
– get an inspection
– seal gaps between attic and living space to keep warm air out
– make sure you’ve got good insulation
– if you’re gonna prod them with a stick like the guy below, make sure nobody’s standing there!
