Dome rooflight price: what affects your quotation?
In this guide — jump to a section
Main price factors
- Dimensions, shape and quantity: standard or bespoke size, round, rectangular or another version.
- Material and build-up: acrylic, polycarbonate, layer count or TOPtermo; clear or opal layers.
- Upstand: new or existing, material, height, insulation and roof junction.
- Opening: fixed, manual or powered ventilation, roof access, or smoke and heat exhaust.
- Accessories: controls, weather sensor, safety mesh and other agreed options.
- Work on site: access, dismantling, installation, connections and agreed roofing finishes.
For replacement, check the existing upstand
Before replacing only the top section, confirm the dimensions, upstand condition, fixings and compatibility of the new dome. Photographs help with an initial estimate but do not replace verification of measurements and condition before manufacture. If the roof is being refurbished, also state any planned additional insulation.
How do you compare two quotations?
Check that both cover the same material, layer build-up and dimensions. Then compare the upstand, drives, controls, safety equipment, transport and installation. Check the scope of electrical work, roofing finishes and removal of old elements separately. Ask for a clear list of inclusions and exclusions, and whether VAT is included.
What should be clearly stated in the quotation?
Two quotations can only be compared when they describe the same solution and the same scope of supply and work. As well as the final amount, check the following items.
| Item | What should be specified | Why it matters |
|---|---|---|
| Rooflight element | Nominal dimensions, shape, material, colour and number of layers. | Two domes that look similar do not necessarily have the same performance. |
| Upstand | New or existing; material, height, insulation and geometry. | The price of the upper element does not automatically include a new upstand. |
| Opening | Purpose, mechanism, power supply, controls and sensors. | Ventilation, roof access and natural smoke and heat exhaust are different functions. |
| Work on site | Inspection, measurements, removal, installation, connections and roof junction details. | “Including installation” may cover different work in different quotations. |
| Logistics | Transport, unloading, lifting, access and disposal of removed components. | Size, quantity and roof access affect how the work is carried out. |
| Terms | VAT, quotation validity and the anticipated schedule following confirmation. | The price and schedule apply as stated in the current quotation. |

Three different scopes that should not be treated as equivalent
Supply of the element
The product without installation or alterations to the roof.
A coordinated system
A dome with the agreed upstand, opening mechanism or accessories.
Work on site
The agreed inspection, removal, installation and other clearly specified work.
If an item is unclear, check whether it is included, excluded or provided by another contractor. This avoids comparing the price of a dome alone with the price of a complete refurbishment. For a non-standard size, also see bespoke dome rooflight options (Slovenian).
For a comparable quotation
Send the location, quantity, a dimensioned sketch, photographs, room use and the required scope of supply or installation.
Why is there no universal “from” price?
Without a defined configuration and scope, such a figure could be misleading. We prepare a quotation from your project details, not from one photograph of a similar dome.
Details for an initial estimate
Send the location, quantity, measurements with labelled measuring points, photographs, room use and required opening. State whether you need supply only, a new-build installation or replacement with installation, and give your preferred approximate timeframe.
