Skylights and rooflights in Cotgrave

Cotgrave counts as both a town and a civil parish, within Rushcliffe borough in Nottinghamshire and five miles south-east of Nottingham. Its modern shape comes from one decision. Cotgrave Colliery opened in the early 1960s, and large numbers of miners and their families were moved from other mining areas of England, especially the North East, to live on a large purpose-built housing estate. In 1962 around 500 experienced mining workers took up the National Coal Board's offer of tied new houses complete with furnishings, coming from the area of the recently closed Radford Mine on the north-west side of Nottingham.

A planned estate is a gift to a surveyor and a puzzle to a designer. It is a gift because roofs built to one plan usually repeat their pitch and build, so what we learn on one street helps on the next. It is a puzzle because the houses were designed for one kind of family life, and the families who live in them now want something else. They want the kitchen opened up, the loft used, the back bedroom lighter. That is where a rooflight comes in. It adds light without moving a wall, and the roof is often the one place where nothing stands in the way.

The town also grew a centre to match. A shopping parade called the Precinct was built at the same time as the large housing estates, with a Co-op, a library, a fish and chip shop, take-aways, other retailers and a medical centre. A third pub, the Black Diamond, was built in the early 1980s, closed in 2006, and was demolished and replaced with housing known as Diamond Cottages. Those are small details, but they show a place that was added to in stages rather than all at once, and newer homes sit among the older plan. Where a more recent house stands beside a 1960s one, the roof construction can differ even though the street looks uniform, so we confirm the timbers house by house.

Reading a regular roof carefully saves time on the day. We check the pitch of the slope, the position of the ridge and the eaves, the depth of the rafters, and the height from the loft floor to the underside of the roof. From those four measurements we can say which of the standard size codes will sit in the slope and how much headroom the finished window will give. For a code such as MK04, width is the letter and height is the number, and a short slope above a tall room can pull the choice two ways.

The land around Cotgrave has changed more than most towns' surroundings. The extensive former mining area has been landscaped as a country park, with a long section of the Grantham Canal partially restored, including at least two locks. The canal is not presently navigable, and some nearby road bridges have been removed. The A46 runs nearby, and during improvements in 2012 and 2013, excavations uncovered Ice Age flint tools. Windmill Hill stands about a kilometre away on the mapping data. For anyone with a view of that open ground, the sky is a big part of the outlook, and a rooflight puts more of it in the room.

Wind is worth a paragraph of its own. On open ground a roof takes more weather than a sheltered terrace does, so the fixings, the flashing and the way a kerb is tied to the roof structure matter more. We write those details into the quote, and we dress the flashings against the covering that is actually on your roof, whether that is tile, slate or a flat membrane, so the junction is made for the material.

Open ground changes how a roof is used. There is less shade from neighbouring buildings and more wind. A flat-roof unit sits on a kerb, a low box of upstand around the opening, and on an exposed site the kerb needs to be well fixed and the flashing dressed with care. We specify both at the survey so the quote covers the detail.

Choosing between the two is mostly a question of height and width. A flat roof rooflight sits low and suits a modest extension, or one where a neighbour overlooks the roof. A roof lantern stands above the roof and gives a room a ceiling of glass, with a skyline that is part of the house. It needs more headroom outside and a stronger frame inside, and it looks best on a room wide enough for the proportions to work.

Think, too, about what the room is for. A loft study wants steady, even light for a screen, a bedroom wants the option of darkness, and a landing wants only enough to find the stairs. The same roof can hold a fixed unit in one place and an opening one in another. Blinds that fit the frame, sold by the manufacturers for their own units, give the dark when it is wanted. We talk through the room at the survey and fit the plan to the use, so the first quote already reflects the way the space will really be lived in.

Houses built to a standard of the early 1960s were not designed to the insulation levels expected today. When a new rooflight goes in, the glazing is a chance to improve the room it serves. Part L 2021 limits heat loss in an existing home to 1.4 W/m²K through a roof window (Window Energy Rating band B is the alternative route) and 2.2 W/m²K through a rooflight. We choose a unit that meets those figures, and we line the reveal so that the cold does not find a way round the frame.

The railway that served the pit has gone from the picture. A branch of 2.75 miles was extended in 1960 from the Nottingham to Grantham line, across the River Trent past Radcliffe on Trent to the colliery, but the mapping data finds no station within 2 km of the town now. Getting here is by road, and from Leicester the journey is about 29 minutes.

Rushcliffe Borough Council, a Nottinghamshire authority and not a Leicestershire one, takes the planning questions, so a Cotgrave job is dealt with by a different office from the ones we see most. On a house, planning permission is seldom the hurdle, since Class C in the 2015 permitted development order allows rooflights. What it asks is easy to meet: no more than 150mm of glass standing off the slope, nothing taller than the roof's own peak, and on any side-facing slope a frosted, fixed window unless the section that opens is over 1.7m up.

On conservation, the register is silent: it holds no conservation area inside 1.5 km of Cotgrave. The source itself says council submissions can be incomplete for some authorities, and that the absence of a record should not be read as a statement that there are none. We treat it the same way. Designation by itself leaves Class C intact, whereas an Article 4 direction would withdraw it, so check your address with Rushcliffe early.

Escape from a loft room is a Building Regulations point worth settling early. Under Approved Document B an escape window counts only on floors 4.5m or less above the ground. Convert the loft of a two-storey home and the escape is a protected stair, while the roof window brings light. If a bedroom in the roof is the plan, we say so during the survey and the stair is discussed before the glass.

Getting started is a short message. Fill in the quote form, or write over WhatsApp, naming the room and street and attaching a roof photograph if you can. We survey for free and then send a fixed quote in writing for you to read when it suits.
