Conservatory Roofing Materials
A conservatory is one of the most crucial home improvement additions to your home, and the roof is the most critical part of any conservatory. A strong but lightweight roof is essential as it holds the entire structure together. As well as being watertight, it has to withstand heavy snowfalls in winter and strong sunlight in summer to endure the worst British weather for many years whilst still looking good. To ensure that your conservatory is finished with the best quality and highest-performing roof possible, we are pleased to introduce the ‘ultimate’ new polycarbonate X25 roof system, an easy-to-fit, strong, and thermally efficient conservatory roof system. Roofs can be supplied double-glazed with energy-efficient glass panels to form a high-quality glass conservatory roof.
As a roof supplier manufacturer, we can build any conservatory roof design as a new or replacement conservatory roof to upgrade your existing roof. Polycarbonate conservatory roofs are very popular as a cost-effective solution for roofing conservatories, garages, sheds, greenhouses or anywhere that needs a roof that lets in light.
Lean To Roof
We have solar control sheets for south-facing garden roofs to reduce heat build-up. Solar sheets reduce heat like a solid roof system and allow natural light to come in, preventing other rooms in your home from becoming dark. The global roof system is a favourite glazed roof option among roof installers, offering Liniar conservatory roof external coverage in various lengths and sizes at a given pitch (in the plan). For standard roof projections, the dimensions below are the actual coverage of the external projection for each bar length. Dimensions change according to the pitch of the roof.
Note:
1. The overhang of approximately 40-50mm into the gutter
2. External sizes rounded to the nearest 5mm

FAQ's
Can I use self-supporting glazing bars for glass roofs? Our roof system is manufactured using different strength bars, which can be used to take glass double-glazed roof panels.
Can I replace my polycarbonate with glass? Usually, the existing roof bars will also need to be replaced. The glass is much heavier, and the bars need to be stronger.
Conservatory roof glass or polycarb? Glass is quieter. It reduces noise when it rains; glass also has a high solar gain, so it can be beneficial in north-facing or shady areas. The disadvantage of glass on south-facing gardens is that the heat build-up inside the conservatory has more options. Both opal and heat guards can dramatically reduce heat during the summer months. A heat guard is a perfect choice for a south-facing garden.
How long does a roof last? There is very little to go wrong with the roofs. The materials are all guaranteed for at least ten years, but when appropriately fitted and maintained with occasional cleaning, a lifespan of twenty to forty years is possible.
What is the best option for a conservatory roof? Lean-to-roof kits with heat guard conservatory roof sheets can reduce the heat in the summer by 85%. There is a loss of light, but it's worth it for the shade in summer. Opal sheets are cheaper and are the preferred choice for most installation companies.
