Conservatory Roof Replacement FAQs (Answered by Experts)

What are the main types of conservatory roof replacement?

The most common replacement options are polycarbonate, glass, tiled roofs, and insulated roof panels. Polycarbonate is usually the cheapest but offers the weakest insulation. Glass is brighter but often loses heat quickly. Tiled roofs provide strong insulation but are the most expensive and involve more structural work. Insulated roof panels such as Cosy Panels provide a balance of insulation, cost, and ease of installation.

How much does a conservatory roof replacement cost?

Costs vary depending on the size of the conservatory and the type of roof chosen. A small polycarbonate roof is at the lower end, while a tiled roof conversion is often at the higher end. Insulated roof panels usually fall in the middle, making them a practical choice for homeowners who want value as well as performance.

How long does installation take?

A tiled roof replacement can take a week or longer because of the extra structural work. By comparison, insulated panels are often installed in just a few days. This is because they are designed to slot into the existing frame, reducing disruption.

Do I need planning permission?

In most cases, replacing a conservatory roof does not require planning permission. However, if the replacement changes the overall height or structure, or if you live in a listed property or conservation area, checks may be needed. Building regulations may apply depending on the type of roof.

How long do replacement roofs last?

The lifespan depends on the material. Polycarbonate can discolour or weaken after a decade or so. Glass often lasts longer but requires regular cleaning and maintenance. Tiled roofs are designed for long-term use but at a higher cost. Insulated roof panels from Cosy Panels are built to last many years with minimal upkeep.

Will a new roof improve energy efficiency?

Yes. A well-insulated roof helps to retain warmth in winter and keep the space cooler in summer. This reduces the need for heating or cooling, leading to lower energy bills. Insulated roof panels are particularly effective for this purpose.

Can I still use my conservatory during installation?

Some disruption is unavoidable during roof replacement, but it is usually limited. With insulated roof panels, installation is quicker and less intrusive, meaning the conservatory can be used again soon after the work is finished.
