The back roof of our terrace runs a long way. Where should a loft roof window go?
Victorian terraced houses in northern England usually have natural slate roofs, often with a long uninterrupted rear slope. For a loft room, that slope is the natural place for a roof window, because it is out of sight of the street and there is plenty of room to choose a position.
Where along the slope
A window set low in the slope gives a view of the garden from a chair or a bed. One set higher puts more light into the middle of the room and keeps the sill clear of furniture. In a bedroom a good answer is somewhere between: a window you can see out of when seated, with the handle within reach of someone standing. We mark the position with you at the survey, because the rafters decide what is possible.
The covering
The flashing kit that seals the window to the roof is chosen to match the covering, so we note whether it is slate or tile, and its condition. The slate and tile flashing guide explains why. We note the state of the slates around the position too.
Sharing the room
Think about who else will use the loft. A young child may need a handle out of reach and a window that opens only a little, provided the room's escape window, if it has one, still opens fully for an adult (see the Building Regulations guide), while an older relative needs controls that do not ask for a stretch. Those decisions are far easier to make before the window is ordered than after it is in.
Controls and blinds
Choose how the window will open at the same time as the position. A manual window with a pole is enough for a study. A bedroom used daily suits a motor and a blind on the same handset. Our blinds and controls guide compares them, and the loft conversion guide covers sizes.
