Energy Efficient
Outstanding insulation keeps your room warm in winter and cool in summer.
We replace outdated orangery roofs for homeowners and commercial property owners who want better thermal performance and year round comfort. Guardian Warm Roof UK works as certified installers for Guardian warm roof systems, and we design and install bespoke lightweight conservatory roofs too.
Our orangery roof replacement service covers both domestic properties and commercial buildings. We handle everything from initial survey through to final installation, working with Guardian orangery roof systems and other cutting edge roofing systems that transform how your space performs.
Guardian is the brand leader in warm roofs and the only warm roof company to have Trustmark Scheme status. This certification reflects independent testing that Guardian undertakes and the certified installer scheme it operates. When you choose us, you get access to systems that Guardian Slate and Metrotile have independently fire tested with BRE, achieving BROOF(t4) classification in accordance with EN 13501-5:2016.
Your existing orangery probably suffers from problems that make the space uncomfortable and expensive to heat. Older glazed or partially glazed orangery roofs lose significantly more heat than modern insulated solid roof systems, and heating accounts for approximately 55 percent of the average UK household energy bill.
Many glazed extension roofs installed 15 to 20 years ago were built to lower thermal standards than those required today. During UK summer heatwaves, poorly insulated glazed extensions have recorded internal temperatures exceeding 40°C. If your space becomes unbearably hot in summer and freezing cold in winter, your polycarbonate conservatory roof or existing fibreglass system is failing you.
Water ingress around roof lantern bases is one of the most common long-term maintenance issues in older orangery roofs. The UK experiences over 150 days of rainfall per year on average, and raised roof features such as lanterns are exposed to greater wind uplift pressure during storms. Moisture absorption and internal plaster damage often indicate your roof has reached the end of its functional life.
Roof only orangery replacement is significantly more cost effective than demolishing and rebuilding the entire structure. We retain your existing conservatory walls and foundations, which cuts costs and reduces disruption to your property.
Labour typically accounts for 30 to 40 percent of the overall roof replacement cost in the UK. By keeping your existing orangery structure intact, we focus our work where it matters most – installing a thermally efficient roof that transforms the space into a fully integrated living area.
Estate agents consistently report that year round usability is a key factor in whether an orangery is viewed as an asset. Over 70 percent of UK buyers now prioritise energy efficiency when viewing properties. Upgrading an outdated orangery roof can reposition the space from a seasonal room to a proper extension that adds between 5 and 12 percent to a property's value in the UK.
Adding a glass lantern transforms how light enters your orangery. We install Guardian roof lanterns, Stratus roof lantern systems, and Ultrasky roof lantern products depending on your preferences and budget.
High performance roof lantern glazing, including double or triple glazing with Low E and solar control coatings, improves energy efficiency while preserving natural light. Solar control glass reduces heat gain and glare while maintaining brightness within the space. Solar control glazing can reduce solar gain by up to 60 percent while maintaining natural light.
Larger orangery roofs, especially those incorporating lanterns, require more complex structural integration. The lantern becomes the focal point of the space, adding height and architectural impact that flat roof orangery designs cannot provide.
Beyond roof lanterns, we install Guardian Solstice skylights and Velux roof windows that add natural light without the scale of a full lantern. These options work well in lean to style extensions or where planning permission considerations limit roof height.
We fit low energy spotlights and roof downlights to supplement natural light. This combination ensures your space remains bright and usable even during darker months when natural light is limited.
Orangery roof installation costs vary based on size, material choices, and features like roof lanterns. We provide transparent pricing after surveying your existing orangery to understand the scope.
**We need your spec, options & sizes before we can give you a quote
Simple ladder kits and straightforward flat roof replacements cost less than complex designs with multiple lanterns or gable end features. Four simple ladder kits might suit a basic rectangular orangery, while bespoke designs require custom fabrication that affects pricing.
Many installation companies quote without understanding the full scope, leading to price increases during work. We survey thoroughly and quote accurately because we understand how Guardian warm roof systems and other roof systems work in practice.
We price based on material volume and installation time. Larger projects require more materials but benefit from economies of scale. A small orangery roof conversion kit might cost proportionally more per square metre than a larger commercial installation.
We serve both homeowners looking to upgrade and replace their existing conservatory and commercial property owners who need reliable year round spaces. The approach remains consistent, but commercial projects often involve multiple orangery roof systems installed simultaneously.
Since 2025, UK home improvement spending has increased substantially as more homeowners invest in upgrading existing space rather than moving house. This trend drives demand for orangery roof replacement services that transform underused spaces into valuable living areas.
