Conservatory Roof Replacement St Albans

Most of the conservatories we work on around St Albans date from the late 1990s to the mid 2000s, which means a polycarbonate roof on a white uPVC frame. Those roofs hold almost no heat. The room is cold from November, unbearable in a July heatwave, and rain on the panels is loud enough to carry through the house.

There are two ways to fix that. A full tiled roof replaces the structure entirely and turns the conservatory into a proper room. An insulated ceiling fits inside the roof you already have, costs considerably less, and lifts the thermal performance without structural work. We will tell you which one your conservatory actually needs when we survey it.

Our workshop is at Overstone Grange Farm in Moulton, a straight run down the M1 into AL1, AL2, AL3 and AL4.

Conservatory Insulation and Insulated Ceilings in St Albans

Where the frame and glazing on your conservatory are still sound, an insulated conservatory ceiling fitted inside the existing roof is the quicker and cheaper route. We build an insulated layer beneath the glazing and finish it in plastered board or uPVC panelling, both of which sit flush and leave the room looking like part of the house rather than a conservatory.

An insulated ceiling holds heat in through winter, keeps the worst of the summer sun out, and cuts the rain noise sharply. Most installs take a single day. If your roof is past saving, or the polycarbonate seals have already failed, we will tell you that insulation is the wrong answer rather than take the easier sale.

Tiled Conservatory Roof Conversion in St Albans

A full conversion replaces the glazing and framework while keeping your existing base and walls, which is what keeps the cost well below an extension. We build a solid tiled roof around a custom timber frame cut to your conservatory rather than assembled from a standard kit. Timber conducts far less heat than aluminium, and the extra depth lets us pack in more insulation, bringing the finished roof to a U-value of 0.15. A ventilated void above the insulation stops moisture building up in the structure.

At survey we check the base and the wall plate first, because a tiled roof is heavier than polycarbonate. We build to Edwardian, Gable, Lean To, P-shape and Victorian conservatory shapes. Building control sign-off comes through Stroma and the work carries an insurance-backed guarantee of up to ten years.

Replacing a Polycarbonate or Glass Conservatory Roof

Polycarbonate discolours and the seals between the panels fail, which lets in draughts long before anything leaks. Glass roofs hold up better but still leave you with a room that overheats badly in summer. Patching individual panels on either rarely buys more than a season.

We strip the old roof, take it away, and build the new structure onto the existing frame, usually inside two to three days. Same footprint, same doors, and a room you can use in February.

Conservatory Roof Replacement in St Albans: Your Questions Answered

How much does a replacement conservatory roof cost in St Albans?

It depends on the size and shape of the conservatory and on whether you want a full tiled roof or an insulated ceiling, which is the cheaper of the two. [CONFIRM: publishable price range]. We give a fixed written price after survey.

Do I need building regulations approval?

For a full tiled roof, yes, and we handle it for you with sign-off through Stroma Building Control plus an insurance-backed guarantee of up to ten years. An insulated ceiling fitted inside the existing roof is not usually notifiable, and we will confirm which applies to your job at survey.

Can my existing conservatory take a tiled roof?

Often, though not always. The base and wall plate have to carry the additional weight, and our surveyor checks both before quoting. Where the structure will not take it, an insulated ceiling gives you most of the comfort benefit without the load.
