Replacement Conservatory Roof

Many conservatories built years ago have sound walls and frames but a roof that makes the room too hot in summer, freezing in winter and noisy in the rain. Old polycarbonate sheets discolour and leak, and early glass roofs may lack modern solar control coatings. A replacement conservatory roof can transform how usable the room is without rebuilding the whole structure. This page explains the options in general terms from our base in Weston-super-Mare.

Glass roof replacement

Replacing an old polycarbonate or tired glass roof with modern glass keeps the bright, open feel of a traditional conservatory. Today's roof glass can include coatings that reflect solar heat and reduce glare, along with self-cleaning finishes. Glass is heavier than polycarbonate, so the existing frame and base must be able to carry it.

Solid and tiled roofs

A solid or tiled roof turns a conservatory into something closer to an extension. Lightweight tiles or slates sit on an insulated structure, often with a plastered ceiling inside, and can include roof windows or glazed panels to keep some daylight. The room usually feels warmer in winter, cooler in summer and quieter in heavy rain. Because the roof is heavier and more substantial, the condition of the walls, frames and foundations has to be checked.

Conservatory conversion

A conservatory conversion goes beyond the roof, for example replacing some glazed side frames with insulated walls, upgrading doors and improving the floor. The aim is a room you can use all year. Depending on the extent of the work and how the room joins the house, Building Regulations may apply, and an insulated solid roof normally needs building control approval. Check with your local building control team before committing to a design.

Conservatory roof replacement cost

We do not publish prices, because every conservatory is different. The cost of a replacement roof depends on the size and shape of the conservatory, as Victorian and P-shaped roofs are more complex than a lean-to; the type of roof chosen; any work needed to strengthen the frame or base; internal finishes such as plastering and lighting; access around the property; and building control requirements. A survey gives the information needed for a fair quote.

Signs your conservatory roof needs attention

Common warning signs include leaks at the ridge or where the roof meets the house wall, discoloured or brittle polycarbonate, condensation dripping from the roof bars, loud rain noise, and a room that is too hot to use for much of the summer. Gutters that overflow or have pulled away can also point to wider roof problems. Noting which of these you see helps a survey focus on the right issues.

Keeping light in the room

One worry with a solid roof is losing daylight. Roof windows, glazed panels set into the solid roof and light colours on the ceiling inside all help keep the room bright.

Before you decide

Ask how the existing frames and base will be assessed, what building control involvement is needed and how the junction with the house will be weatherproofed. For an overview of conservatory styles, see our conservatories page, and when you are ready, send photos of the roof and its frame through the quote form.
