What a roof window actually is
A roof window sits in the slope of a pitched roof, in line with the tiles, rather than in a vertical wall. Because it faces the sky rather than the horizon it takes in far more daylight than a wall window of the same size, which is why one in a loft or a back extension changes a room so completely. Most open by pivoting on a centre hinge, so the sash rotates and you can clean the outside face from inside the room. “Roof window”, “skylight” and “rooflight” all describe much the same thing; what matters is that the unit is rated for your roof.
- It sits in the slope of the roof, in line with the tiles, not in a vertical wall
- Facing the sky rather than the horizon, it takes far more daylight than a wall window the same size
- Most pivot on a centre hinge, so the outside of the glass is cleanable from indoors
Why people choose us for this
Three things that are true of every skylight we fit.
Josh surveys every job himself
One point of contact from enquiry to finish, and the person who surveyed the roof is the one who fits it.

Not a separate subcontractor brought in for the roof, which is where the flashing detail usually gets missed.

New install, replacement, or repair?
What we do with skylights
- New installationA general roofer can fit a roof window, but the flashing-by-covering detail is where a glazing specialist earns their keep.
- ReplacementSwapping an old or failed roof window for a new unit, matched to your existing opening.
- RepairA roof window can often be repaired rather than replaced. We've done exactly this job before.
A leading-brand roof window, or a budget one?
A fair question, and an honest answer: a budget unit is genuinely cheaper, it's just not the same thing.
| A leading-brand roof window | A budget own-brand unit | |
|---|---|---|
| Recognition | A name most buyers already recognise | Less recognised, which can matter at resale |
| Product range | A dedicated range for low-pitch and flat roofs | Range varies a lot by brand and stockist |
| Price position | Sits at a higher price point | Genuinely cheaper, honestly |
| Parts and aftercare | Widely stocked parts and blinds for years to come | Can be harder to source parts for later |

Which roof have you got, and will a roof window fit it?
The flashing kit and the pitch range it can go in both depend on which of these is yours.
Profiled interlocking tiles
Prone toThe wrong flashing kit fitted for the tile profile, which is the most common cause of a leak.
How we treat itA dedicated interlocking-tile kit, matched to your tile profile.
Natural or artificial slate
Prone toA tile kit fitted on a slate roof, or a slate that's too thick for the kit rated for it.
How we treat itA slate-specific kit, matched to your slate thickness.
Flat or low-pitch roof
Prone toA standard roof window that isn't rated for a pitch this shallow.
How we treat itThe dedicated low-pitch or flat-roof product range, built for this pitch.

Cost
What actually drives the cost of a roof window
Every job is quoted
We don't publish a price list because it genuinely depends on your roof and what you want fitted. What you get instead is a proper survey and a fixed, written quote with nothing hidden in it.
- How many windows, and what size
- Your roof covering, and the flashing kit it needs
- Whether a rafter needs trimming to open the roof
How it works, survey to finish
No salesman, just the job done properly.
The survey
Josh comes out himself, checks your roof covering and confirms which product fits it.
The quote
You get a written, fixed quote back with the flashing kit and product already worked out.
The fit
We open the roof, fit the window and flashing, and make good behind us.

AKI 95
Very happy with our skylights installed by Josh, very professional, Polite and very clean and has changed our whole kitchen I very highly recommend if you are from Bournemouth or Surrounding areas
Andy
Josh installed our new windows, triple track doors, roof lights and front door at our house in Bournemouth. A very professional, tidy and efficient service from beginning to end. Would highly recommend Wilshaw Glazing.
Natasha Evans
Josh and his team worked incredibly hard replacing all of the windows and doors in our house, including fitting a beautiful bifold door in place of our old French doors. We could not be happier with the results. The quality of the workmanship was excellent, and Josh was fantastic with communication throughout the whole process. He was reliable, professional, and kept us updated every step of the way. We would highly recommend him to anyone looking for high-quality work and great service.
The bits people worry about
Will it actually look right on my roof, not obviously bolted on?
A well-matched flashing kit sits flush with your roof covering, which is most of what makes it look fitted, not stuck on.
What if my loft conversion doesn't meet Building Regs?
We'll flag anything that looks off at survey. We never promise compliance before we've actually looked at the room.
How long is my roof open to the weather while it's cut?
We open, fit and weather it back up as one continuous job on the day, not left open overnight.
What goes wrong when it's fitted badly
Nothing dramatic, just the sort of thing that shows up a year or two later.
The wrong flashing kit
Fitted for the wrong roof covering, it leaks at the frame, usually not straight away.
A rafter cut without trimming
Cut without proper trimmer rafters either side, it can sag over time.
Condensation
Poor ventilation around the opening can stain a newly plastered ceiling.
Fitted properly
The flashing mistake most fitters skip
AluSpace, our internal aluminium screening system, is a separate product and isn't covered on this page. The part that actually decides whether a roof window performs well over time isn't the window itself, it's the flashing kit around it. Flashing kits are matched to the roof covering they're going into, and fitting the wrong one for your roof is one of the most common causes of a leak at the frame.
- Interlocking profiled tiles take their own dedicated flashing kit
- Natural or artificial slate needs a different kit again, rated by slate thickness
- Plain tile, recessed slate and flat-tile roofs each have their own matched kit too
Turning your loft into a proper room
Will the council let you fit one, and is your new room legal?
If your loft is becoming a habitable room, not just a storage space, the new roof window may need to double as an escape route. That means a clear openable area of at least 0.33m², with neither side smaller than 450mm, and a cill no higher than 1,100mm off the floor. Planning permission is a separate question from Building Regs, and it's always worth checking the current edition of the regs before we quote a specific job.
- Clear openable area of at least 0.33m², minimum 450mm each way, cill no higher than 1,100mm
- Planning permission and Building Regs are two separate questions
- Always confirmed against the current regs and your local authority, never assumed
Ventilation, and the duty most quotes skip
Building Regs Part F requires background ventilation, typically trickle vents, on most new and replacement windows, and a roof window is no exception.
A loft conversion room is particularly prone to condensation if this gets skipped, because it's often smaller and more enclosed than the rooms below it. It's a five-minute detail to get right at quoting stage, and an expensive one to fix after the ceiling's been plastered.
How much does it cost to have a roof window fitted?
It genuinely depends on the product, size and your roof covering, so we don't publish a fixed price. Book a survey and we'll come back with a written, fixed quote.
Do I need planning permission to put a roof window in my loft?
Most roof windows fall under permitted development, so usually no. See the Building Regs section above for the escape-window and ventilation rules that can apply, and always check with your local planning authority if there's any doubt.
Is a budget roof window worth it?
It genuinely can be, it's just a different product with different aftercare and resale recognition. See the comparison above for the honest trade-offs.
Do roofers fit roof windows, or do I need a specialist?
A roofer can physically fit one, but matching the flashing kit to your roof covering is glazing work, and it's the most common thing that gets missed.
Can a roof window be repaired rather than replaced?
Often, yes. We've carried out skylight repairs before, not just full replacements.
What happens next, and how long does fitting take?
We'll book a survey, confirm the product and flashing kit needed, then send a written quote. We won't promise a fitting time until we've actually seen the job.
