A warm roof is a fully insulated roofing system designed to replace traditional conservatory roofs made from glass or polycarbonate. Unlike older conservatories that can be too hot in summer and too cold in winter, a warm roof uses insulated panels and internal plasterboard to create a room that feels much more like a normal extension.

Yes. In most cases an existing conservatory roof can be replaced with a modern insulated warm roof system without needing to replace the existing frames or structure. This is one of the most popular upgrades for homeowners who want to make their conservatory usable all year round.

Yes. Warm roofs are designed with multiple layers of insulation which significantly reduce heat loss compared to glass or polycarbonate roofs. This helps the room retain warmth during colder months while also preventing overheating in summer.

Yes. Many warm roof systems can include roof windows or glazed panels to allow natural light into the space while still benefiting from high levels of insulation.

In most cases, planning permission is not required when replacing an existing conservatory roof, as the work is generally considered an improvement to the existing structure rather than a new extension. However, building regulations may apply because replacing a glass or polycarbonate roof with a solid insulated roof changes the thermal performance and structural load of the conservatory. LEKA insulated roof systems are designed specifically to meet these requirements. LEKA systems are supported by MFA (Modern Fenestration Approval), an industry-recognised compliance scheme that helps ensure the roof system meets current building regulations for structural integrity, insulation and safety. Working with an installer who registers the installation with MFA helps simplify the process, as the roof design, calculations and compliance documentation are already recognised within the industry. This helps provide reassurance that the installation meets the required standards while avoiding unnecessary complications.

Most warm roof installations can be completed within 2–4 days, depending on the size and complexity of the conservatory. This makes it a relatively quick way to transform the space without major building work.

Yes. Warm roof systems are commonly used not only for conservatory upgrades but also for new extensions, garden rooms and orangery-style spaces where strong insulation and a traditional roof appearance are desired.

The cost of a warm roof depends on several factors including the size of the roof, the shape and the specification. As a guide, most homeowners find warm roof replacements to be significantly more affordable and time saving than building a new extension while still delivering a similar improvement in comfort.

Most conservatories are suitable for a warm roof replacement, but the structure will usually be assessed first to ensure it is strong enough to support the new roof system. Modern systems are designed to be lightweight while still providing excellent insulation.

Many homeowners find that replacing their conservatory roof transforms a space that was rarely used into a comfortable room that can be enjoyed all year round. It can also improve energy efficiency and add value to the property.
