The landing in our terrace has no window at all. Sun tunnel or roof window?
Ashton-in-Makerfield sits on the Lancashire Coalfield, and in 1867 there were 13 collieries in the district. A house with its stair and landing in the middle of the plan can leave the top of the stairs dark even at noon, because it sits away from the outside walls. A rooflight can fix that, and the choice comes down to what you want from it.
What a sun tunnel does
A sun tunnel is a small dome on the roof joined by a tube through the loft to a diffuser in the landing ceiling. It brings in daylight and nothing else. It does not open, it gives no view, and there is nothing to reach or clean on the inside. It suits a landing, a bathroom or a hall with loft space directly above. Our guide to which rooms suit a sun tunnel lists the rooms it works in.
What a roof window does
A roof window needs a way through the ceiling and a short light shaft down to the landing. It gives a view of the sky, and it can open to clear steam or cooking smells from a stairwell. It also sits high, so the opening method matters. A rod will do for a window you seldom open. A remote or a solar motor is easier if you will open it daily.
Who is it for?
Think about the people on the stairs. A landing used by a child or an older relative is helped by steady daylight on the way down and little else. A landing where you hang washing in winter may call for a window that opens. We look at the loft from above during the survey and tell you which of the two your roof will take. Our guide to roof windows for loft rooms covers the other route.
For a landing
Choose the sun tunnel for daylight alone, and the roof window when you want to open it or look out.
