Rooflight Project Costs: What to Include in Your Budget

A rooflight budget should cover the complete project, not just the glass. Compare the same specification and include the work needed to fit it before deciding what offers good value for your home.

If you are considering resale appeal, read our guide to rooflights and home value. There is no guaranteed increase in sale price. This checklist focuses on what to include in your project budget.

Start with a configured product price

Browse our rooflight range, select the listed size and available glass options, and review the resulting price. A starting price is not a quotation for a different size or specification. Check whether each amount includes VAT when comparing suppliers.

A raised roof lantern is a different product from a flat rooflight. Compare suitable alternatives for your roof and room rather than assuming the cheapest headline price describes the same product.

Separate supply from installation

SmartaView supplies the product only. Ask your installer for a written breakdown of the site work so you can see what is included and what remains your responsibility.

• Surveying and confirming the required finished order dimensions.
• Structural work and preparation of the opening, where required.
• The correct upstand or kerb, insulation and roof-weathering details.
• Access equipment, lifting and safe handling of the unit.
• Fitting, internal reveals and making good the surrounding finishes.
• Removal of an existing unit and waste, where relevant.

These are items to check, not a statement that every project needs the same work. Agree the scope with the professionals responsible for your roof.

Check standard and bespoke costs separately

An online standard size is not a confirmed price for a larger bespoke rooflight. Availability, glass construction, handling and delivery arrangements may differ. Use our sizing guide and bespoke quotation checklist to label the dimensions correctly before requesting a price.

Do not scale a website price by glass area and treat the result as a final quotation. Obtain written confirmation of the exact product and specification before ordering.

Compare quotations like for like

• Complete rooflight or replacement glass only.
• Finished dimensions and the measurement basis.
• Framed or frameless design and any visible border or finish.
• Double or triple glazing and the exact selected glass specification.
• Documented performance and the applicable guarantee terms.
• VAT-inclusive total, delivery postcode, access requirements and confirmed lead time.

Keep the selected specification with the quotation. If anything changes, ask for the revised price and delivery information before accepting it. Our rooflight buying checklist covers the final checks.
