Replace tired polycarbonate or single-skin glass roofs with a thermally-insulated solid roof system - typically inside a week. Use the room in January. Use it in July. Use it every day.
LABC-compliant warm-roof systems · structural assessment included · 10-year insurance-backed guarantee.
Most British conservatories built before 2015 are unusable for half the year. A warm-roof conversion replaces the failed roof - usually polycarbonate - with an insulated thermal-laminated system that transforms the room into an all-year space.
Old conservatory roofs fail in three ways at once: thermally, acoustically and structurally. The room becomes an expensive storage area.
UV exposure yellows polycarbonate within 10–15 years. Algae growth between layers is permanent. Leaks become routine.
Older glass roofs use sealed units that mist or fail at the gasket. Replacing individual panels rarely solves the underlying frame problem.
Single-skin roofs amplify rainfall to conversation-blocking levels. Heavy rain makes the room unusable for watching TV.
Polycarbonate roofs hit 40°C+ in July, drop below 5°C in January. Heating and cooling costs are prohibitive year-round.
We measure, photograph, check the existing frame's structural capacity, discuss roof tile finish, rooflight positioning, internal finish and external eaves detail.
You receive: roof system, reinforcement (if needed), rooflights, plastered finish, downlights, external gutters and downpipes - itemised in writing.
Warm-roof conversions require LABC building-regs approval. We submit the application and manage inspections on your behalf - typically 2–3 weeks.
Strip existing roof (1 day), structural reinforcement if needed (1 day), insulated rafters and decking (1–2 days), waterproof membrane and tiles (1–2 days), internal plasterboard and skim (2–3 days). Typical total: 7–10 working days on site.
LABC final inspection, certificate issued, 10-year insurance-backed guarantee registered, 25-year tile manufacturer warranty, walkthrough complete.
Use the conservatory every day - comfortable in January, cool in July.
Thermal performance jumps from U-value 2.8 (polycarbonate) to 0.18 (warm roof) - a 90%+ reduction in heat loss.
Plastered ceiling and insulated rafters reduce rainfall noise to the same level as the rest of the house.
Typically returns 100–130% of conversion cost in property value - and removes the 'unusable conservatory' deduction at sale.
Skylight rooflights retain natural daylight while delivering room-grade insulation.
LABC-approved system with full certification at completion - important at resale.
Warm-roof conversion is shorthand for a structurally engineered, building-regs compliant roof system replacing the original conservatory roof. Five variables decide the result.
Tapco SuperRoof for the most popular lightweight composite tile system, Metrotile for ultra-light metal tile finishes, and Equinox / Guardian Roof for systems with integrated insulation and structural rafters. All are LABC-certified and carry 25-year tile warranties.
Original conservatory frames were designed for polycarbonate (lightweight). Warm-roof systems are heavier - typically 35–55 kg/m². Most original frames can accept the additional load with light reinforcement (steel ties, additional supports). Some require frame upgrades. The structural assessment at survey confirms what's needed before quote.
Velux roof windows in 600x800, 800x1200 or 1200x1200 sizes integrated into the warm-roof system. Typically 1–3 rooflights per conversion to retain daylight. Solar-tube alternatives available for narrow positions.
Plasterboard fixed to underside of insulated rafters, joints taped and skimmed to a finish indistinguishable from the rest of the house. LED downlights wired and certified by qualified electrician. Coving and architraves to match existing house style.
Lightweight composite or metal tiles in slate grey, terracotta, charcoal or heather brown. Aluminium gutters and downpipes in colour-matched powder coat. Eaves trim and lead flashing to existing wall and chimney where present.
