Where there was once a void between plasterboard and the exterior cladding, there are now various layers of breathable membrane and thick foam board insulation (Celotex) to keep us toasty when using the upstairs bathroom.
Rather than use UPVC or cement board cladding to cover the exterior, I have copied many of the other neighbourhood dormers and decided on dark roofing tiles instead. These should blend in better with the existing roof tiles, be very durable and look less dirty than white cladding.

The handy blokes have done a very neat job of battening round the windows and hanging the tiles. It’s already starting to look a lot nicer than the old dormer but the key thing is whether or not the added insulation will cut down on condensation often leading to black mould on the bathroom ceiling after a few hot showers. I’ll be keeping a close eye on this.

Lashings of insulation, new rubber roof properly angled to prevent pooling water and guttering added. In short, it’s almost a completely new dormer less a full re-build.
My one gripe because there’s always something that’s less than perfect in my own little world is that they’ve left a line of exposed ragged edges at the point where the roofing tiles join the lead flashing. I would have expected a bit of brown trim or something to cover the exposed gap. Maybe I'm just fussing.

Actually, there is one other tiny grizzle and that is in the way the tiles have been hung. They are perfectly straight but I feel the overall appearance might have looked better if the overlap rows had been closer together. I realise this would have meant using more tiles, maybe a tighter overlap may have provided greater weather-proofing as well as looking less clunky. God, you’re so picky!
