Does a red-brick terrace loft take a roof window, and where does it go?
Edwardian brick terraces commonly have Welsh slate roofs, and a terrace has a front slope on the street and a back slope over the yard or garden. For a loft room the back slope is the natural place for a window. It takes the light from the rear, it is out of sight from the road, and it is usually a plain run of slate.
What we read on the roof
The flashing kit has to suit slate, and the width of the window follows the rafters behind it. Both are things we measure at the survey, not from a photograph. Our page on flashing on slate roofs explains the kit.
Planning in brief
A rooflight on a house is usually permitted development, within limits that the planning guide sets out. A roof slope that faces the side carries extra conditions, which the guide describes. In a mid-terrace the slopes face front and back, which keeps things simple, but we confirm the position for your address.
Making the loft a room
A loft turned into a bedroom is building work, so the room upstairs must have a safe route out, and our page on the Building Regulations covers what that involves. Where our roof windows need a Building Regulations notification, we make it.
Cleaning the glass on slate
A slate roof is not one to climb. Ask whether the outer pane of the window you pick can be turned and wiped from inside, and agree the method with us before you order. A window you can clean from the bedroom floor is one that stays clear.
Choosing the opening
The top of a window in a sloping ceiling can sit above head height. If you will open it every day, electric or solar opening is easier than a rod. See roof windows for loft conversions for sizes and positions.
