Conservatory Roofing Eastbourne

Conservatory Roofing in Eastbourne

Eastbourne's conservatory stock spans three main generations: 1990s lean-to and Victorian-style uPVC with polycarbonate roofs, 2000s–2010s glass roof systems, and more recent tiled solid roof conversions. The coastal climate accelerates failure in all three types — UV degradation of polycarbonate, seal failure in glass units from thermal cycling, and mortar and flashing failures in solid tiled systems if not correctly specified for coastal conditions.

We cover all conservatory roofing work across Eastbourne — repair, replacement and full conversion. Our standard for coastal-adjacent properties is code 4 or 5 lead on all abutment flashings and sill junctions, stainless fixings throughout, and GRP or aluminium rather than felt on any flat sections.

Polycarbonate vs Glass vs Solid Tiled Roofs

Polycarbonate has a useful life of 7–10 years near the Eastbourne seafront and 10–15 years inland due to UV degradation. Glass conservatory roofs — self-cleaning thermally broken units — are significantly more comfortable and have a 20–30 year seal life. Solid tiled roofs are the warmest and quietest option but require a structural assessment of existing conservatory base walls. We carry out all three types.

Abutment Flashings — The Critical Junction

The junction between conservatory roof and house wall is the most common failure point. The correct specification is lead code 4 stepped flashing over a lead soaker course, dressed into a raked mortar chase minimum 25mm deep. We find DPC tape, self-adhesive flashing band and silicone on a significant proportion of Eastbourne conservatory surveys — all are temporary measures with a 2–5 year lifespan. Correct lead flashing, done once, will outlast the conservatory structure.

East Sussex Planning Position

Conservatory roof replacement — polycarbonate to glass or polycarbonate to solid tile — is generally permitted development in Eastbourne. Converting to a fully habitable room (with full insulation and heating) requires building regulations compliance. Solid roof conversions often trigger a thermal bridging assessment. We advise on planning and building regulations position at survey stage.
