Thinking about improving your home, but worried about the cost? You’re definitely not the only one. With home improvement prices rising across the UK, it’s no surprise that big projects like extensions or new kitchens can feel out of reach.
The good news is, you don’t always need to spend a fortune to make a big difference. If you’d love more space but can’t justify the cost of a full extension, replacing your old conservatory roof could be the smartest, most cost-effective upgrade you make this year.
A tiled conservatory roof gives you the same warmth, comfort and style as an extension, but for a fraction of the price. It’s one of the most affordable home extension ideas around, helping you make better use of the space you already have, without the stress or the sky-high costs.
Conservatory Roof Replacement vs a Full Extension
When you think about adding space to your home, a traditional extension might be the first thing that comes to mind. But while extensions can look great, they often come with lengthy build times, significant disruption and a hefty price tag.
It’s not just the price of materials, either. With a full extension, you’re paying for groundwork, new walls, flooring, plumbing, electrics, and often months of building work – not to mention the planning permission process, disruption to your home, and builders on-site for weeks at a time!
A conservatory roof replacement, on the other hand, avoids all that. It makes use of your existing structure, meaning there’s no groundwork, no planning permission in most cases, and it can usually be installed in just three to four days for a typical 4m x 4m Edwardian-style conservatory. That’s why it’s always going to be the more affordable, less stressful option, especially if you already have a conservatory and you’re happy with the space it gives you.
You’ll also benefit from:
- Brilliant energy efficiency – U-values as low as 0.15 W/m²K to keep your space comfortable all year round.
- Quick installation – completed in days, not months.
- A seamless look – your conservatory will blend beautifully with your home.

How Much Does a Conservatory Roof Replacement Cost?
So, what does it actually cost to replace a conservatory roof in the UK?
While prices vary depending on the size, shape and features of your conservatory, most tiled roof replacements start from around £10,000. Larger or more complex designs will naturally cost more, but even at the higher end, a SupaLite roof is still far more affordable than building a brand-new extension.
A new home extension typically costs around £3,000 + VAT per square metre. For a modest 10m² build, that’s roughly £30,000 + VAT.
By comparison, a SupaLite tiled conservatory roof replacement (without frames) costs around £1,000 + VAT per square metre, or about £10,000 + VAT for the same size. If you’re replacing the frames too, the price rises slightly to around £1,500 + VAT per square metre (£15,000 + VAT for 10m²).
That makes a SupaLite conservatory roof up to 60% cheaper than building a new extension, with the added benefit of less upheaval and a much faster turnaround.
Because SupaLite works through a network of Premium installers, we can’t set or guarantee exact prices. Costs will depend on your location, roof design and chosen finishes. For an accurate figure, it’s always best to speak to your local installer, who can provide a tailored quote for your project.
What Affects the Cost of A Tiled Conservatory Roof
Every conservatory is different, and a few factors will influence your overall roof replacement cost, including:
- Roof shape and size – larger roofs need more materials and time to install.
- Tile choice – select from ExtraLight shingle, ExtraLight classic, or Tapco Slate tiles in a range of colours to suit your home.
- Optional extras – add glass features like SkyVista panels or an S1 Roof Lantern to let in more natural light.
- Location and installer rates – costs can vary slightly depending on where you live in the UK.
Whatever you decide, you can be confident every SupaLite roof is precision-built, fully tested, and designed to meet Building Regulation standards.
What’s Included in the Price?
Every SupaLite roof installation includes the removal of your old conservatory roof, a fully insulated replacement system, internal plasterboard finish, and your chosen tile style. Optional extras, such as downlights or glass panels, can be added by your installer for a bespoke finish.
This transparency ensures you know exactly what you’re paying for, with no hidden surprises.
New Conservatory vs Extension – What’s Cheaper?
Even if you’re planning to build a brand-new conservatory with a SupaLite tiled roof, it’s still much cheaper than building a traditional home extension, and they often give the same results. Here’s how they compare based on current UK market averages:
Even if you start from scratch, a new conservatory with a SupaLite tiled roof can cost less than half the price of a full extension, and gives you the same look, comfort and value!
