We install premium conservatory roof replacements for homeowners and businesses throughout the country. Our team at Guardian Warm Roof UK specialises in p shaped conservatory roof replacement services, transforming outdated and underperforming structures into comfortable spaces you can use throughout the year.
As Guardian certified installers, we bring manufacturer-approved expertise to every project. This certification means we follow strict installation standards and use only genuine Guardian products, giving you complete confidence in the work we deliver.
We serve both domestic and commercial properties. Whether you need a roof replacement for your home conservatory or a larger commercial structure, we have the experience and accreditation to complete the work to the highest standards.
P shaped conservatories combine two distinct architectural styles in one structure. The design joins a lean to section with a Victorian or Edwardian projection, creating a unique shape that maximises floor space and provides distinct areas within a single extension.
This conservatory style is typically found on detached homes and larger properties where there is sufficient garden space to accommodate the extended footprint. The rounded part of the structure usually projects into the garden, while the lean to section runs along the property wall.
The combination creates versatile design opportunities. Many homeowners use the separate sections for different purposes, with one area serving as a lounge area and another functioning as a dining area or combined dining area.
Around 20 percent of UK homes have a conservatory, and p shaped conservatories represent a significant portion of installations on larger properties. The UK market includes an estimated 3 to 4 million conservatories, making it one of the largest conservatory markets in Europe.
The size and complexity of p shaped conservatories mean roof performance becomes particularly important. With greater roof surface area and multiple sections meeting at different angles, heat loss and temperature control issues become more noticeable than with simpler conservatory styles.


Guardian is the brand leader in warm roofs and the only warm roof company to have Trustmark Scheme status. This certification is a testament to both the independent testing that Guardian undertakes and the certified installer scheme it operates, giving you complete peace of mind.
Guardian Slate and Metrotile have been independently fire tested with the roof system by BRE and in accordance with EN 13501-5:2016, achieving BROOF(t4) classification. This fire rating demonstrates the safety and quality built into every Guardian Warm Roof installation we carry out.
There are cheaper warm roofs on the market. We acknowledge that upfront, because we believe in transparency about your options.
However, Guardian represents the Rolls Royce of warm roofs. The difference lies in rigorous testing, certified installation networks, and proven long-term performance that cheaper alternatives simply cannot match.
When we install a Guardian warm roof on your p shaped conservatory, you receive a system that has been engineered specifically to work with existing conservatory frames. This reduces the need for full structural rebuilds and keeps costs considerably lower than complete demolition and reconstruction.
We also design and install bespoke lightweight conservatory roofs when specific project requirements call for custom solutions. Our experience with both Guardian systems and bespoke designs means we can recommend the perfect approach for your property and budget.


Not every homeowner wants a solid roof. Some prefer to maintain maximum natural light while still upgrading thermal performance and weather protection.
We install high-performance glass roof systems that deliver modern thermal efficiency without blocking light. These systems use advanced glazing technology including solar control coatings and argon-filled sealed units.
Solar control glass reduces heat gain during summer months while maintaining excellent light transmission. Self-cleaning glass can be incorporated into replacement roof systems to improve comfort and reduce maintenance, particularly useful for the higher sections of p shaped conservatory roofs that are difficult to reach.
Glass panels in modern roof systems achieve thermal performance that would have been impossible with older glazing technology. While not matching the insulation values of solid tiled roofs, contemporary glass systems perform vastly better than the polycarbonate or basic glass in your existing roof.
The glass roof option suits homeowners who use their conservatory primarily as a bright, airy space for plants or as a seamless transition between house and garden. The natural light creates an airy feel that some people prefer over the room-like environment of a tiled roof.
