Which kind of roof window suits the low-pitched roof on our estate house?
Council estates of the 1950s and 1960s in England typically have concrete interlocking tiles on low-pitched roofs, and some have flat-roofed blocks. Bredbury has the Shakespeare Estate, built by Manchester City Council as an overspill development. Whether your own house is one of that kind, we see from the street and the loft at the survey, because the roof decides what can go in it.
The covering sets the kit
A roof window is fitted with a flashing kit made for the covering around it. Interlocking concrete tiles need a different kit from slate, and the wrong one lets water in. That is why we look at the tiles before we suggest a model, and why the guide to flashing on slate and tile roofs is worth a read.
A shallow slope in summer
The shallower the slope, the more directly the glass faces the sky. A room under it can run warm on a sunny afternoon. A blind on the inside takes the edge off, and solar control glass is a further option. The guide to solar control glass sets out what it does.
Reaching it
On a low roof the window can sit closer to head height, which suits a hand-operated one. On a landing or stair where you cannot reach, a rod or remote is the answer. We note where you will stand to work it, and whether anyone shorter than you will need to use it too.
Some blocks have flat roofs
Where a flat-roofed block or a flat-roofed part of a house is the place for the light, a flat rooflight or a lantern is the choice, and the questions become cleaning and shade rather than flashing. The guide to upstands and roof coverings explains how the covering is checked around the opening. If the block holds flats rather than houses, a rooflight on a flat goes through a planning application, and the freeholder usually has to agree as well, as the planning guide explains.
