The room you stopped using is about to become your favourite.
A tiled roof is the difference between a conservatory you tolerate and a room you actually live in. Here’s what changes — and why most clients say they’d have done it years ago.
Five things you’ll notice in the first week.
It stops cooking in summer
Polycarbonate roofs turn conservatories into greenhouses. A tiled roof with proper insulation kills the solar gain — you can sit in it on the hottest day of the year.
It holds heat in winter
U-value 0.15 W/m²K is better than the Building Regs minimum for a new-build extension roof. The room stays warm with a fraction of the energy.
It quietens the rain
The drumming on a polycarbonate roof is the most-named complaint we hear on surveys. A layered tiled roof reduces that to almost nothing.
It cuts your bills
You stop trying to heat a leaky greenhouse. Most clients see a meaningful drop in their winter heating costs and stop running portable AC in summer.
It adds value to the home
An insulated, Building Regulations-compliant room counts as habitable space. That helps at survey, at sale, and when you re-mortgage.
It lasts.
40+ year tile lifespan, 10-year insurance-backed guarantee, no recurring repaint or panel-swap costs. It’s a one-time job, done properly.
The single biggest change is how often the door stays open.
Most clients tell us the same thing about a month after handover: the room is just used. Working from it. Reading in it. Eating in it. Watching telly in it on a December evening with the rain hammering down outside, barely audible.
A tiled roof doesn’t add a room. It recovers one.
That’s the gap between a conservatory you walk past and one you walk into. The thermal performance is what makes it possible. Everything else — the decor, the lighting, the furniture — you’d already do, if only the room was worth furnishing in the first place.
Tiled vs polycarbonate vs glass vs new extension.
The four real options for an underperforming conservatory roof, side by side.
| Polycarbonate | Glass | Supalite Tiled | Full extension | |
|---|---|---|---|---|
| U-value | ~ 1.2 W/m²K | ~ 1.0 W/m²K | 0.15 W/m²K | ~ 0.18 W/m²K |
| Year-round usable | No | Marginal | Yes | Yes |
| Building Regulations compliant | n/a | n/a | Yes — LABC/LABSS approved | Yes |
| Reuses existing base & frame | Yes | Yes | Usually yes | No — rebuild |
| Typical install time | 3–5 days | 3–5 days | 5–10 days | 8–16 weeks |
| Rain noise | Loud | Moderate | Almost none | None |
| Indicative cost | £ | ££ | £££ | £££££ |
All figures indicative. Real numbers depend on conservatory size, existing structure and your spec. We’ll give you specifics on survey.
You’re not building a room. You’re unlocking one.
A full single-storey rear extension typically runs £35,000–£60,000 once you factor in foundations, walls, roof, glazing, plastering, decorating and a new floor — before VAT and any planning costs. A Supalite tiled roof transforms the room you already have for a fraction of that, in a fraction of the time, and without losing any of the conservatory’s windows or doors.
For most homes, it’s the most cost-effective square-meter you’ll ever spend on a property — because you already paid for the floor space the first time round. You’re just making it count.
