Warm Roof Specialists Covering Lostwithiel
Lostwithiel is part of our mid-Cornwall route from our Plymouth Barbican workshop. We've completed work for customers in the town, and we coordinate Lostwithiel visits with Bodmin and Liskeard so travel stays efficient and the price stays the same as it would be in Plymouth.
Lostwithiel is a historic river town, and its housing reflects that: older stone and rendered properties around the town centre and the bridge, plus later housing on the edges where conservatories were added through the 1980s, 1990s and 2000s. We're used to conservatories built against older, irregular walls — proper lead flashing chased into the masonry, never a bead of silicone.
We fit one system — the LABC-approved SupaLite warm roof — which means our crew is faster and the finish is more consistent than installers who switch between brands.
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 Lostwithiel Conservatories Stop Being Usable
- Valley damp and rainfall — the Fowey valley sees plenty of rain, so rain noise and ridge-bar leaks are the two complaints we hear most.
- Ageing polycarbonate — 25–30 year old sheets go brittle, discolour and lift in wind.
- Summer heat and winter cold — glass and polycarbonate roofs make the room unusable at both ends of the year.
- Condensation — cold roof surfaces drip back onto sills and frames through the winter.
- Bespoke shapes on older walls — conservatories built against irregular stone need proper lead flashing, not silicone.

Why our warm roof outperforms a traditional conservatory.
Frequently asked questions.
Do you cover Lostwithiel?+
Yes. Lostwithiel and the surrounding Fowey valley villages are covered from our Plymouth Barbican base, and we've completed work for customers in the town.
How much does a warm roof cost in Lostwithiel?+
All conservatory roof replacements start from £6,000 fully fitted, regardless of size or shape. There's no distance premium for Lostwithiel — pricing matches our standard Plymouth pricing. Final cost depends on conservatory shape, tile finish, number of skylights and any internal finishing.
How soon can you survey in Lostwithiel?+
Lostwithiel surveys are typically within 7–10 working days, as we coordinate visits across mid-Cornwall to keep travel efficient. The survey is free, takes around 45 minutes and comes with no obligation.
Will my Lostwithiel conservatory need Building Regulations approval?+
Almost always, yes — a warm-roof replacement changes the thermal envelope of the room. We handle the application, the inspector's visit and the final certificate through Cornwall Council on your behalf.
Can you work on older properties in Lostwithiel?+
Yes. Lostwithiel is a historic town with a high proportion of older stone and rendered properties, and conservatories here are often built against irregular walls. We chase lead flashing properly into stonework rather than relying on silicone.
How long does an install take?+
Most projects are 2–4 days. A 3m × 3m lean-to is typically 2 days, an Edwardian or Victorian 3.5m × 3.5m around 3 days, and a larger gable or P-shape 4 days. One crew works continuously and your home stays watertight every night.
What guarantee do I get?+
A 10-year insurance-backed workmanship guarantee, plus a 40-year manufacturer guarantee on the composite tiles.
