Where should the loft window go on a slate terrace with a long back slope?
A Victorian terrace in a northern mill district usually has natural slate on its roof, and the back slope is often long and unbroken. That gives plenty of room to place a window, and it means the decision is less about whether one will fit and more about where it will do most good.
Position
A loft room needs the window high enough to see out of when you stand, and low enough to reach from where you sit or lie. A single wide window gives a lot of light. Two smaller ones give a more even spread and let you shade one while keeping the other open. We mark the positions on the slope and inside the room at the survey, so you can see what each choice would mean.
The slate itself
The flashing kit is chosen to match the slate, and the slates beside the window are lifted and put back. Our guide to flashing for slate and tile explains why the right kit matters.
A bedroom under the slope
A loft bedroom needs a blind that makes the room dark, and a window that opens without a climb. A rod, or an electric or solar motor, suits a window above reach. The new floor also needs a safe way out, which our Building Regulations guide explains. We take care of the Building Regulations notification for the windows we fit, where one is needed.
Light across the day
A rear slope faces whichever way the terrace happens to point, and that decides when the room is bright. A window that suits a morning bedroom may be too hot as an afternoon study. We ask which hours you use the room, and then pick a blind, or a glass, to fit them.
