On a steep street the back roofs sit at different heights. Does that change the window?
Steep terraces branch off the main streets in Tyldesley, and houses in a row can step up or down the slope. That can put the back roof of one house higher off the ground than the next, and a roof window at the back of an upper house can be out of reach of anything but a long ladder.
Why the roofs step
Tyldesley sits at the edge of the Lancashire Plain, north of Chat Moss, on a sandstone ridge known as the Banks where the Pennine foothills begin. Steep terraces branch off the main streets on that ground. It is not a hill-country town, and weather is not the theme. The slope matters for a more everyday reason: it puts one back roof above another.
Reach from inside and outside
Inside, a window high in a sloping ceiling is out of arm's reach, so a telescopic rod works a manual one and a remote works an electric or solar one. Outside, the height of the back roof decides how the glass is cleaned. A window on a low back roof can be washed from a ladder in the yard. On a high one, a window that tilts or turns so the outer pane can be reached from inside is the kinder choice. We look at the roof from the back garden at the survey, since a front view does not show you this.
Brick, slate and the flashing
Victorian and Edwardian terraces in Lancashire mill towns are typically red brick under Welsh slate, so the flashing kit is chosen for slate. Our page on roof window flashing for slate and tile explains what the kit does.
Planning and the safe way out
A rooflight on a Tyldesley house is usually permitted development, within limits the planning guide sets out. A loft that becomes a living floor needs a safe route out, covered in the Building Regulations guide. If the work is notifiable, the notification is ours to handle.
For a steep Tyldesley street
Look at the back roof from the garden before choosing. If you cannot reach it, pick a window you can clean and open from inside.
