Will a roof window cope with wind and rain at 230 metres?
Chapel-en-le-Frith is on high ground, about 230 metres above sea level at the centre, with moorland close by. On ground this high, wind-driven rain is a fair thing to plan for. A well-fitted roof window is built to cope. The weak points are usually the flashing around it, which must be the right kit for the roof covering, and the habits of the people who open it.
Closing it when you are out
An open window on a rainy morning can leave a wet sill. VELUX offers a rain sensor on its electric and solar roof windows. When the first drops land on the glass, the sensor shuts the window. If you are at work or away for a weekend, nothing else in the house will do that job. Our guide to rain sensors on rooflights explains how they behave.
Condensation in cold rooms
High ground means colder mornings, and a loft bedroom can show moisture on the glass or round the frame. That is usually about ventilation and the room more than the window. We talk about it at the survey, and our page on condensation on rooflights covers the causes and what can help.
Keeping the outside clear
Leaves, moss and grit settle on glass over time, and a steep roof makes the outside hard to reach. At handover we explain how to clean the window safely, so you know the safe way to reach the glass and when to leave it alone.
Which window for which room
A bathroom or kitchen under the roof gives off steam, and an opening window clears it. A bedroom wants the opposite: a window that stays shut in a storm yet opens a crack for air on a still day. Some makers' controls allow a part-open setting, and we go through the controls at handover.
Weather first, then style
On high ground, choose the opening method for the days you are out, not the days you are in.
