The system

Inside the Supalite tiled roof system.

A purpose-engineered, lightweight, fully insulated tiled roof — built to drop onto your existing conservatory in days, not weeks. Building Regulations compliant, LABC and LABSS approved as a system, with a 10-year insurance-backed guarantee.

What it is

Not a conversion. A proper insulated roof.

Supalite is the UK’s leading lightweight tiled conservatory roof system. It replaces tired polycarbonate or glass with a layered, insulated structure that performs like a new-build extension roof — but is engineered to be light enough to fit onto your existing conservatory base and frame.

Outside, you get the look of a solid tiled roof in your choice of profile and colour. Inside, you get a smooth, vaulted plastered ceiling that you can light, paint and live under like any other room in the house.

Because it’s an approved system — not a one-off bespoke build — every install is built to current Building Regulations as standard. No grey areas.

How it’s built

Six layers, top to bottom.

Every Supalite roof is built up the same way — engineered for thermal performance, structural integrity and a clean internal finish.

01

Lightweight tile finish

External profile in your choice of Extralight (slate-effect / shingle) or Tapco Slate (composite), available in nine standard colours across the two systems. Engineered to weigh a fraction of a traditional clay or concrete tile so the conservatory base can carry it.
02

Tile battens & counter-battens

Treated softwood, set to the tile manufacturer’s gauge. Provides a ventilated cavity above the membrane.
03

Breathable roof membrane

High-performance vapour-permeable underlay. Lets moisture out, keeps weather and wind-driven rain out.
04

Engineered structural frame

Pre-fabricated Supalite spaceframe, sized to your conservatory. Carries all the loads down into the existing frame and base — no external props, no rebuild.
05

High-performance insulation

Multi-layer PIR and reflective insulation, sealed against air leakage. This is what gives the roof its 0.15 W/m²K U-value.
06

Plasterboard & skim finish

Internally, a vapour barrier, then taped-and-jointed plasterboard, then a plaster skim coat. Decorate it like any other ceiling. Add downlighters, a pelmet or Velux windows during the build.

Approvals & certification

Approved system. Properly built.

Replacement conservatory roofs are notifiable work under Building Regulations. The Supalite system is approved by both LABC (Local Authority Building Control, England & Wales) and LABSS (Local Authority Building Standards Scotland) — meaning the system itself has been pre-reviewed against the regulations and signed off as compliant. We install it the way it’s been approved, so every roof we fit is Building Regulations compliant as standard.

If you need a formal Building Regulations completion certificate — typically for a future sale, remortgage, or insurance renewal — we can arrange one through Local Authority Building Control as a separate process. The build itself is to current Building Regulations regardless.

Tile options

Two tile systems. Both lightweight. Both Building Regulations compliant.

Every Supalite roof we install uses one of two engineered tile systems — Extralight or Tapco. Both are approved as part of the Supalite system. The right choice for your conservatory depends on the look you’re after, the existing roofline, and how the tile sits against your brick.

Lightweight tile

Extralight

Engineered slate-effect and shingle tile in a contemporary profile. The lightest of the two systems — ideal where the existing conservatory base is borderline or where you want the cleanest possible roofline.

Available in Classic Black, Charcoal, Ember and Walnut
Lower per-m² weight than the Tapco system
Pairs well with rendered or modern brick exteriors

Composite slate

Tapco Slate

Composite slate tile with a deeper, more textured profile and a wider colour range — including warmer reds and earthy tones. A more traditional aesthetic that blends with older roof lines and period homes.

Available in Pewter Grey, Stone Black, Brick Red, Chestnut Brown and Plum
Deeper texture — reads more like a traditional slate close-up
Pairs well with brick, stone or older roof tiles

Surveyor brings real samples of both systems — Extralight and Tapco — so you can hold them against your own brick before deciding.

Glazing options

Want light? Add a Sky Vista.

Optional rooflights, designed specifically for the Supalite system. Built into the roof during the install. Not part of the standard build — you choose whether you want them at survey.

Optional rooflight

Sky Vista

A flat, double-glazed rooflight built into the tiled roof during the install. Brings daylight into the room without losing the thermal performance of the surrounding insulation. One, two or more, depending on the size of the conservatory and how much daylight you’re after.

Sealed during install — no retro-fitting later
Insulated frame, double-glazed unit
Compatible with the 10-year insurance-backed guarantee

Heated-glass upgrade for Sky Vista

Sky Vista with Glow

An optional upgrade to the Sky Vista — the glass itself is heated. The room warms from above through the rooflight rather than relying solely on a radiator on the wall. Quick to bring the room up to temperature on a cold morning, with no moving parts and nothing to mount on the wall.

Heats the room directly through the glass surface
Wired in during the build — no exposed cabling
Add-on to a Sky Vista — not a standalone product

Inside the room

The ceiling makes the room.

Standard finish is a smooth vaulted plaster ceiling. From there, it’s your call.

Recessed downlighters

Wired in during the build — no scarring the plaster afterwards. Choose dimmable LED units, switched in groups.

Decorative pelmet

A flat soffit border around the ceiling perimeter for hidden cove lighting and a cleaner finish where ceiling meets wall.

Velux roof windows

Add one or more roof windows during the build for daylight without losing thermal performance. Manual or electric, optional rain sensor.

Paint colour

The skim finish takes any standard emulsion. Most clients pick brilliant white to bounce the light, but darker tones work beautifully if you have the windows for it.
