With a Topline conservatory roof conversion, we provide a real live-in all year round room, allowing the light to shine in too. The choice of colours are Matt Grey, Matt Black and White, these can be chosen with any combination on the inner and outer frame, construction is thermally efficient aluminium with A – rated energy glass.

By fitting a modern self-clean glass lantern, upgrades an existing glass or polycarbonate conservatory roof, making your room more modern and better insulated. Often the complaint of old style conservatory roofs is that it’s too cold in the winter and too warm in the summer.


Our glass lantern roofs are built to regulation standards for your peace of mind, the work would include plaster finish inside, ready to paint, with LED downlights in the ceiling.

The new roof is guaranteed by Topline for a 10 year period as is the lantern (please enquire through our office for full details of the terms of our guarantee).

Our refurbishments can include existing Edwardian style or Victorian style conservatories.

Our roof conversions with glass lanterns are available across Portsmouth, Waterlooville, Southampton, Chichester, Emsworth, Havant, Petersfield, Fareham, Winchester and local areas of Hampshire & West Sussex.
