Rooflights for the Whitworth Valley's terraces

Skylights and rooflights for Whitworth homes in the Pennine valley

Whitworth is built around its valley in the Pennines, about 230 metres up. We choose a rooflight that copes with that ground and suits the room, from the handle to the blind.

21 road miles north of Stockport

Whitworth is a town and civil parish in Rossendale, Lancashire, built around the Whitworth Valley in the Pennines. The valley takes in Healey, Broadley, Whitworth, Facit and Shawforth, linked by the A671. By the 19th century quarrying and coal mining were the chief industries, though yarn manufacture stayed important, and a turnpike road built through the valley in the middle of that century helped development.

Whitworth's mill terraces are likely to have stone walls under a stone-slate or Welsh-slate roof. The town stands about 230 metres up, which is high ground, so wind and wind-driven rain are fair things to plan for. In daily use that shows up as a few plain questions. Can you reach the handle? Will the window stay shut when it should? Does the glass mist on a cold morning, and how does the outside get cleaned? We settle them at the survey, before the fixed written quote.

What a valley of stone roofs calls for

Slim windows for stone and slate, glass that copes with the cold, and light for the stairs. These five are chosen for the ground as well as the room.

Using one on a hillside roof

A loft window in a terrace may sit beyond your reach, so a rod covers an occasional opening and a remote covers a daily one.
A blackout blind on a loft bedroom window can run in side channels on some makers' models and work from the same control as the window.
On high ground, a window left open is easily caught by a shower, so a rain-sensing model, where the maker offers one, is worth discussing.
Centre-pivot windows turn over so the outside glass can be cleaned from the room, and we show you how at handover.

Whitworth, from valley floor to the rooflight

High ground, stone terraces, a conservation area and glass that mists on a cold morning give Whitworth surveys four familiar questions.

How much should the weather on high ground shape the window we choose?

Whitworth stands about 230 metres up. That is high ground in the Pennines, and exposure and wind-driven rain are fair things to think about here. A roof window is made to keep weather out when shut. The difficulty is the hours it is not shut, and those are the hours the household chooses.

Open and unattended

A window that is left open on a sunny morning and then caught by a shower is one way a loft room gets wet. A manual window stays as left. Some makers offer a restrictor that holds it a little open so that wind does not swing the sash wide, which is useful in a bedroom. For a room that is empty all day, an electric or solar window with a rain sensor can close itself. VELUX offers sensors on some electric and solar models, and we check whether the one you want has it. Our page on how rain sensors behave goes through the limits.

Hot days as well

High ground has bright days too, and a loft room under a big pane warms up. A blind on the window helps, and solar control glass can be added to the specification. Neither is a reason to avoid a rooflight. Both are reasons to choose with the blind in mind, and to ask about the glass at the survey. Our page on solar control glass for roof windows sets out what the coating does.

In a gust

A window that opens outward and upward catches wind. In an open spot it is worth asking how far the sash opens. We go through this with each maker's product. We do not promise how a window will cope with a particular storm.

Afterwards

Weather also leaves marks on the glass. Rain on a sloping pane leaves streaks, so how you will clean the outside matters from the start.

Dealing with weather, by window type

Manual: You close it; a restrictor limits the swing
Electric: Closes from a remote or a wall switch
Solar: As electric, with no cable
Rain-sensing: On some VELUX models; closes the sash itself

We have a stone terrace with a loft room. How do we reach and shade the window?

A terrace of that kind usually has stone walls and a slate roof of one sort or the other, which the survey confirms. A loft window in such a terrace may sit well above the floor. A window that you can see from the street is a window that should be chosen carefully, and a slim frame set flush in the slope looks better against stone slate than a deep one.

Handle and rod

If the lower edge is within reach, a handle is all that is needed. Higher up, a telescopic rod works for a window opened now and then, and a remote does for one opened daily. A solar model avoids running a cable through the ceiling of a room you have just finished. See centre-pivot or top-hung windows for how the types behave.

Blackout

For a bedroom, blackout is the usual choice. Some makers run it in channels at the side of the window, so that early light does not creep round the edge, and it can be worked from the same remote. For a landing or a study, a light filtering blind may do.

Washing the glass

On a stone-slate or Welsh-slate slope, nobody wants to climb to wash a window. A centre-pivot roof window turns over so the outside glass can be wiped from the room, and that makes a real difference in a loft where you are indoors anyway. A fixed window needs another plan, such as a long-handled brush from a safe position or a clear arrangement for who goes up and when. We say which applies to the window you choose, and show you at handover.

The covering

The covering is checked at the survey. Stone slate and Welsh slate differ in thickness and in how they are laid, so the flashing is chosen to match. The page on flashing for slate and tile roofs explains why that choice matters for a dry window.

For a stone terrace

Slim frame, reachable handle, blind on the same control. Get those three right and the rest is detail.

Why does the glass mist up on a cold morning, and will a new window fix it?

Condensation forms when warm, damp air meets a cold surface, and a pane of roof glass can be one of the coldest surfaces in a room. In a bathroom, a kitchen or a bedroom with several sleepers, it shows on a cold morning as a film on the inside of the glass. It is not a leak, though it can look like one.

What the glass can do

Energy-efficient glazing keeps the inner pane warmer, which makes condensation on it less likely. Makers describe their products in their own terms, and we do not quote figures on the page. At the survey we explain what each glass does and what it will not do. Our page on condensation on rooflights goes through the causes.

Bathrooms and bedrooms

The rooms that mist most are the ones where people wash, cook or sleep. A bathroom with a roof window can steam up after a shower, and a bedroom with two sleepers can show a film by morning. We ask which room the window is for before we talk about glass, because the answer changes what is worth paying attention to.

What you can do

Wiping the glass at the start of the day is the simplest remedy. Opening the window when the room is in use lets the damp air out. A blind closed overnight can trap damp against the glass, so we think about how the blind and the window work together.

Misting between the panes

If the mist is inside the sealed unit, between the two panes, that is a different problem and wiping will not clear it. It means the seal has failed, and the unit or the window needs replacing. See why rooflights mist between the panes.

Misting, in plain words

Condensation: Damp from the room settling as water on a cold surface, such as the inner pane.
Sealed unit: The pair of panes joined at the edge with a gap between them.
Failed seal: A leak in the edge of the unit that lets mist form between the panes.
Energy-efficient glazing: Glass made to keep the inner pane warmer in winter.

We live near Whitworth Square. Does the conservation area change anything?

Whitworth Square Conservation Area was designated in 1974. Living inside a conservation area in England leaves the usual permitted development for a rooflight in place unless something else removes it. What can remove it is an Article 4 direction, and the town has areas covered by them. Because what each one restricts is not something we assume, we check your address with Rossendale Borough Council before we quote.

Listed buildings here

Historic England lists the Church of St John Evangelist, Orchard Cottage and Whitworth House, each at Grade II. A listing belongs to the named building. Where your own house is listed, expect a rooflight to need listed building consent in almost every case, and for that consent to fix the design. See listed homes and rooflights for the steps.

The usual position

With no listing and no direction, fitting a rooflight on an English house usually comes under permitted development, with limits the planning guide lays out, together with the extra conditions on a roof slope that faces the side. An earlier permission with conditions attached can withdraw those rights, so we read the council's record.

A conservation-style window anyway

Where the roof is stone slate and in view, a conservation rooflight with a slim frame and a central bar looks right whatever the rules say. Our page on choosing a conservation rooflight has the options.

Which council handles planning for a Whitworth house?

Rossendale Borough Council. Building control can be done by the council or by an approver registered for building control. Where the work is notifiable, we make that notification ourselves for the windows we fit.

Can an old window in a stone-slate roof be replaced without redoing the room?

It can be, if the new window is the same size as the old one. The old label carries a size code. Reusing the old opening is explained in the page on same or new openings.

Is a rooflight safe in a child's bedroom?

It can be. Some makers offer restrictors to limit how far the sash opens, though the room's escape window, covered in the Building Regulations guide, has to stay fully openable by an adult, and electric models can be run from a remote kept out of reach. We explain each at the survey. See child-safe opening.

Could a sun tunnel brighten a dark stair?

With loft space above, yes. A sun tunnel needs an opening in the ceiling for its diffuser and a clear run to the roof dome. It lights the stair but does not open. See sun tunnels.

How long can a misted window be left?

A window with mist between the panes still works as a window, but the seal has failed and the view and the insulation suffer. See how long a misted rooflight can wait.
