Hello - I wonder of anyone could offer some advice on this or an alternative approach. I like to get more natural light and ventilation into a north facing bedroom. It only has one external wall with no scope to extend the current small window in it. It's a bungalow with a shallow (17 degree) slope concrete tiled roof. The most obvious way to go seems to be a roof window, but the roof trusses are pre-fabricated items at ~17" centres. I want to avoid cutting the trusses as I would have to essentially build a new section of roof for the window to sit in. 400mm wide roof windows don't seem to exist (I could have two side by side - or is there a custom builder out there?), so I was thinking I could get a wider top opener and fit it on a short upstand and centred across two trusses so you can still get at the handle easily. I can live with tidied up exposed trusses inside and it does not need to be a means of escape. Thinking it through, I get a bit stuck at the flashing stage, as I assume I will end up with a gap or very small overlap along the edge of the window between the flashing and the window trim. I suppose I could just bridge it with a flashband or custom trim...but feels a bit messy. Or I forget the factory flashing kit and make my own, but I am not sure where to start with that.
Any advice gratefully received!
Thanks, Ian
