Why we do not publish a price list
It would be easy to put a table of prices on this page. The trouble is that it would be wrong for almost every home that read it. Two roof windows of the same size, from the same maker, can be very different jobs once they meet a real roof. One goes into an open loft through a slate roof that can be reached from inside. The other goes through a pantiled roof over a finished bedroom, needs a scaffold over a conservatory and leaves a ceiling to make good. The window costs the same. The job does not.
A published figure would either be set low enough to catch your eye, and then grow once someone looked at your roof, or set high enough to cover every case, and so be too much for the simple jobs. Neither is fair to you. A survey followed by a written quote is the honest way to price the work, which is why the survey costs nothing and comes with no obligation.
If you would like to understand the numbers before anyone visits, our skylight cost guide for York walks through each factor in more depth, and our roof lantern cost guide does the same for lanterns on flat-roofed extensions.
What moves the price
Every rooflight job is made up of the same handful of parts. How each one plays out on your roof is what sets the figure.
| Factor | What it means for the price |
|---|---|
| Size | A larger unit costs more to buy, and a wider opening needs more structural work around it. |
| Product | Standard roof windows sit at one end; conservation, walk-on and electric units are made to a higher specification and cost more. |
| Glazing | Triple glazing, solar control coatings and laminated inner panes each add to the unit price. |
| Roof covering | Slate, plain tile, pantile and flat roof membranes each take a different amount of stripping, refixing and weathering. |
| Access | Work from inside the loft keeps costs down. A scaffold or tower adds to them. |
| Structure | Cutting rafters means fitting new trimmers, and a large opening may call for a structural check. |
| Finishing | Lining, plastering and decorating the reveal can be part of our work or left for your own decorator. |
Replacement work follows the same logic. Where only the sealed glass unit has failed in a sound frame, the job is smaller. Where the whole unit needs to come out, the price looks more like a new installation, though an existing opening usually saves some of the structural work.
How our written quote is laid out
After the survey we send you a written quote. It is set out line by line, so you can see where the money goes rather than a single figure at the bottom. A typical quote has these sections:
- The product. The make, model, size and glazing of each unit, so you can look it up and compare like with like.
- Access. Whether the work is done from inside, from a tower or from a scaffold, and what that part costs.
- Structural work. Trimming the rafters, forming the opening or building the upstand, priced as its own line.
- Weathering. The flashing kit, membrane and roof covering work needed to make the unit weathertight.
- Inside finishing. Insulation around the frame, lining, plastering and any decorating you have asked for.
- Building Control. The notification and inspection fees where the work is notifiable.
- Terms. How long the quote stands, how payment is arranged, and any deposit, all agreed in writing before work starts.
With the quote comes a plan for each day of the fit, so you know how long we will be in your home and what happens when. If there is a choice to make, such as triple glazing over double, we price both so you can weigh what the extra buys.
What is always included
Some things are part of every job we take on, and they are in the price from the start rather than added later:
- Dust sheets and floor protection on the route through the house and in the work area
- The roof made weathertight at the end of every working day
- Clearing up as we go and a clean-down before we leave each evening
- All waste taken away by us
- The Building Control notification handled for you where the work is notifiable
- Photographs of the hidden work, given to you at handover
- A handover walk-through with the product details, the paperwork and your 10-year workmanship guarantee
You should not find any of these turning up as extras on a final bill. If something is not in the quote, it is not something we will charge you for without agreeing it first.
How to compare quotes
It is sensible to get more than one quote for work on your roof, and we would encourage it. The headline figures are only useful if the quotes cover the same work, so it is worth checking a few things side by side.
- Is the product named exactly, with the make, model, size and glazing? "Velux-type window" could mean many things.
- Is access priced, or will a scaffold appear later?
- Who handles Building Control, and are the fees included?
- Does the price include the inside finish, or only the roof side?
- What happens to the waste?
- Is the roof made weathertight every night, and is that written down?
- What does the guarantee cover, and for how long?
A lower quote that leaves out the plastering or the scaffold is not cheaper in the end. A quote that sets everything out lets you see what you are paying for, and makes it plain if anything has been missed.
