Bespoke Conservatory Roof Specialists
Not every conservatory is a standard shape. P-shape, L-shape, T-shape, gable-end and orangery-style conservatories all need their own setting-out — and that's exactly the kind of work we do best.
We've fitted the SupaLite warm-roof system on every conservatory shape across Plymouth, Devon and Cornwall. The lightweight engineered structure is purpose-built around your existing footprint, including non-square openings, mixed pitches and multiple ridges.
Why most older conservatory roofs stop working.
Almost every project we visit starts with the same set of complaints.
Too hot in summer
Glass and polycarbonate roofs trap solar heat and make the room unusable.
Too cold in winter
Poor insulation lets warmth escape and pushes up your heating bills.
Leaks & condensation
Aging seals and single-skin roofs let damp in and cause recurring leaks.
Loud during rain
Thin roof materials amplify noise so the room never feels settled.
Why Bespoke Conservatory Roofs Fail
- More junctions = more leak points — P-shapes and L-shapes have valleys and changes of direction where old seals fail first.
- Larger volumes are harder to heat — gable-end and P-shape conservatories often have more glass than a standard Edwardian, so heat loss is significant.
- Mixed pitches confuse generic installers — non-specialists struggle with valley details and end up using silicone instead of proper lead.
- Orangery lantern roofs — old aluminium lantern frames sag, leak and lose huge amounts of heat.
- Awkward access — bespoke conservatories often sit against extensions or in tight gardens, which needs experienced site planning.

The SupaLite Warm Roof for Bespoke Conservatories
Our bespoke warm-roof builds use the LABC-approved SupaLite system. Every roof is set out individually around your existing footprint:
- Engineered to your footprint — P-shape, L-shape, T-shape, gable-end and orangery all supported.
- Proper valley detailing — Code-4 lead in every valley and junction, never silicone.
- High-performance PIR insulation — U-values down to 0.15 W/m²K across the whole roof.
- Lightweight composite tiles — slate, pantile or plain tile colour-matched to your house.
- Optional roof lantern retained on orangery conversions if you want natural overhead light.
- Multiple Velux placements across the various roof faces.
- Full Building Regulations sign-off.
- 10-year insurance-backed guarantee + 40-year tile manufacturer guarantee.

Why our warm roof outperforms a traditional conservatory.
Frequently asked questions.
What counts as a bespoke conservatory roof?+
Anything that isn't a standard Victorian, Edwardian, lean-to or double-hipped shape. The most common bespoke shapes we work with in Plymouth are P-shape, L-shape, T-shape, gable-end, orangery-style and one-off conservatories built against unusual house walls.
Can a SupaLite warm roof be fitted on a bespoke shape?+
Yes — that's exactly what the SupaLite system was designed for. The lightweight engineered structure is built around your existing footprint, including non-square openings, mixed pitches and multiple ridges. We've fitted SupaLite on every shape from simple lean-tos to elaborate P-shaped orangeries.
Do bespoke conservatories take longer to fit?+
Slightly. A standard Victorian or Edwardian is 2–4 days; a bespoke P-shape, L-shape or gable is usually 4–5 days because of the extra setting-out and additional ridge details. One dedicated crew works on site continuously.
How much does a bespoke conservatory warm roof cost?+
Bespoke roof replacements start from £6,000 fully fitted, but most P-shape, L-shape and gable projects sit in the £8,000–£14,000 range depending on size and complexity. Every quote is bespoke after a free home survey.
Do you cover gable-end and P-shape conservatories?+
Yes — gable-end, P-shape, L-shape and T-shape are all part of our regular work. The SupaLite system is engineered to handle these shapes, and we deal with the additional ridge and valley details as part of the design.
Can you fit a warm roof on an orangery?+
Yes. Orangeries are essentially bespoke conservatories with a brick perimeter and lantern roof. We can replace the lantern roof with an insulated SupaLite system, often retaining a glazed central roof lantern for natural light if you want one.
Will I need planning permission for a bespoke warm roof?+
Almost never. Replacing a conservatory roof on the existing footprint is usually permitted development, even on bespoke shapes. Building Regulations approval is required for the thermal change, which we manage on your behalf.
