A small attic, a window that opens
The usual answer for a cottage attic is a compact roof window in the rear slope, sized to sit between two rafters so the old timbers are left alone. The sash swings out on a hinge, worked from a handle at the top. A vent bar, a slim gap at the head, lets night air in with the sash down. Over a bed, a handle within reach gets used. A pole gets left in the cupboard.
Some cottages stand hard against a neighbour's gable, so a roof window may be the only way to bring daylight into the stairwell or a back bedroom. Placing the new opening on the garden slope keeps the street view tidy.
Stone, slate and the timbers behind them
Older roofs in the village are covered in a mix of natural stone tiles, clay tiles and slate, and the rafters under them are not always where you would expect. Before quoting, we go up into the loft as well as out into the garden, and say plainly whether one unit or a pair suits the timbers. A new opening in a roof is building work: the structure around it has to be trimmed properly, and the finished window has to meet the regulations.
Charfield falls under South Gloucestershire Council for planning. Any listed cottage needs listed building consent for a roof change, and a home in a conservation area can face extra rules, so ask the council first. What counts as permitted and what needs an application is set out in our rooflight planning guide.
If an existing rooflight on a cottage has gone cloudy because the sealed glass has failed, the answer is a new sealed unit or a new frame. Taking out a whole unit and fitting a new one counts as notifiable work. We send the notice to Building Control for you. Where only the glass unit is swapped in a sound frame, that is generally not notifiable. Our misted and failed rooflights page explains the choice.
A cottage with a rear lean-to can take the work in stages. The attic gets its roof window first, because that is where heat gathers. The lean-to, a dim utility or kitchen behind the main house, can follow with a flat rooflight that opens, so cooking steam has a way out at ridge height instead of drifting up the stairs.
The weather matters too. Open ground below the Cotswold edge catches a good deal of wind and rain, so we choose glazing and flashings to suit an exposed slope, and the sash is built to stay tight when closed.
Asked whether a village roof can take a bigger opening, we measure first and answer second. Spacing between old rafters is rarely even, and a window that looks generous on paper may need a lot of timber cut away. A slightly narrower unit, set between the timbers, is simpler to fit and leaves a stronger roof.
