Lightweight Insulated Conservatory Roofs

As a family-run business with deep roots in the Spalding and Peterborough communities, our reputation is built on every single job we do. When you choose Foster and Son, you’re not just hiring a contractor; you’re partnering with a team that genuinely cares about protecting your home.

The main reason our customers choose a replacement is for comfort. An insulated warm roof completely changes how you can use the space. It stops the sun from turning your conservatory into a greenhouse and prevents heat from escaping in winter. This creates a comfortable room you can use every day, reduces your energy bills, and cuts down the noise from rain and wind. Plus, a solid, tiled roof can significantly improve the look of your home.

To safely replace a glass or polycarbonate roof without having to rebuild the conservatory's foundations or frames, we use a specialist lightweight tile system. These tiles look just like traditional slate or concrete tiles but weigh a fraction of what they do. This allows us to create a beautiful, durable, and fully insulated roof structure that your existing conservatory can support.

This is a common concern, but the reality is often surprising. While a solid roof is not transparent, the room becomes much more usable. The walls are still mostly glass, letting in plenty of natural light. We can also incorporate roof windows (like Velux) into the new design to bring in even more light from above. Many customers find they enjoy the space more because the light is softer and there is no harsh glare.

Most projects are completed surprisingly quickly. For an average-sized conservatory, our experienced team can typically strip the old roof and install the new insulated roof system in just a few days. We work efficiently to minimise disruption and help you start enjoying your new space as soon as possible.

Absolutely. High-performance insulation is at the heart of the system. We use multiple layers of modern, rigid insulation boards between the roof timbers. This creates an exceptionally thermally efficient barrier, which is what keeps the room at a stable, comfortable temperature. The project is finished internally with plasterboard and a skim finish, just like any other room in your house.

Yes, we have extensive experience in conservatory warm roof conversions. Over the years, we have helped countless homeowners across Spalding, Peterborough, and the surrounding areas reclaim their conservatories. We understand the specific needs of these projects and use industry-leading materials and techniques to deliver a first-class service and a fantastic finished product.
