Yesterday morning with the melting snow I noticed a leak from our butterfly roof. As I currently have scaffold up, I got onto the roof and shovelled off most of the snow that was on the roof and also in the central channel and this stopped the leak. Should I worry about the leak? It is raining quite heavily today and there doesn't seem to be a leak. It has only happened due to the melting snow and ice. Can the snow and ice get under the tiles?
 
We had a couple of leaks into our house this weekend. The areas are directly below valleys were snow had accumulated on the valley and the first row of tiles each side.

I haven’t been able to brush the snow off (too high) so I’m keeping my fingers crossed it’s a one off.

This problem hasn’t present itself in lighter snow and very heavy rain - so I’m hoping it just the volume of snow and subsequent defrost.
 
This very fine dusty snow has literally blown up the roof with loads of people seeing something of some sort. Hopefully next couple days everything back to normal.

I take it from your username you are in the trade? If so that’s a reassuring comment!
 
I went up in the loft room on Friday, and found a 3" pile of snow that had blown in through the vent on the Velux window. I've never seen the likes of this snow before.
 
My soffits in my not yet finished extension are open at the minute. Had snow inside. Mad wind and super dust like snow. Really weird weather.
 
Thanks for all the replies - no more leaks now the snow has gone and have read a few US websites that talk about ice dams getting formed on the roof so the melting water backs up.
