Icicles.

[nonomaybe]

Belatedly, my thoughts have turned to icicles.Talking about them to a person from the very far North(NOT HIM!!) it has been suggested that the presence of Icicles indicates a heat leak.I know that there is a horde of heat/ventilation experts lurking by their keyboards, so chaps and chappettes what do you say??

I would have said that the presence of icicles indicates a drip....

Woof, I think your needed on the Body and Soul site!!!

[nonomaybe]

that should have read...."you're" rather than your.

Well my loft is fully insulated and boarded out, and I have double glazing throughout my bungalow...................I have massive icicles at the mo.

Gutters full of snow, then a slight thaw would give you some nice icicles (nicicles?).

A hot-spot somewhere would cause it, but would be fairly evident by looking at the snow-covered roof, I would think.

[woofgang]

lol there's a lot of them about...

We may be "sliding" to a concensus but my house is,a la "craft" well insulated and double-glazed with massive icicles but only at one corner.Following Naz's line I should surely have icicles along the whole gutter line as we have had snow and sub-zeros for a couple of months.Looking at the snow on the roof gives no indication other than that there is plenty of snow on the roof which will stay until after Easter(usually!!)

[woofgang]

aha!! I bet you've got water lying in the corner of your gutter and a slow leak!

[nonomaybe]

I'll have a look.

Here, nearly every building locally is festooned with big icicles. It would seem that heat leaking from the inside of the roofs is melting the underside of the snow. The meltwater runs down the roof and drips into the guttering, where it freezes. The guttering fills with ice and further meltwater then overflows to form the icicles. What's strange is why the snow, wet on its underside, hasn't slid off the roofs. With a rise in temperature forecast for later this week, everyone had better watch out. Some icicles are 3 to 4 feet long or more. Being impaled by one of these could be lethal.

How come we have icicles on our shed when there is no heat source there?
