Guardian Warm Roof

Guardian Warm Roof

The Guardian Warm Roof Conversion System is the biggest revelation to hit the home improvement market in the last ten years.

A Guardian Warm Roof is a unique and innovative solution which will transform your existing conservatory into a ‘cosy’, all-year-round living space with reduced rain noise and sun glare. The roof system is designed to replace the existing glass or polycarbonate roof of a conservatory (with zero condensation risk over the life of the roof) while retaining the original windows, doors, frames and walls. At the same time providing substantial energy cost savings. The complete changeover takes our installation experts just a few days with minimal disruption.

Conservatory Roof Upgrades

Fully tested and approved to all thermal and structural standards, the Guardian roof is a high performance insulated roof system comprising of a pre-engineered lightweight frame, two layers of rigid insulation board, internal insulated plasterboard, exterior grade plywood, vapour membrane and a choice of external tile finishes.

A Guardian Warm Roof can be fitted on all types of conservatory (or Porch), including:


Lean-to: The Guardian Lean-To forms a perfect extension to any kitchen and increases the space available at the back of a house. It can be positioned with one or two slopes and is capable of going as low as 15 Degrees with roof windows.

Edwardian: This is the traditional and classic style of a Guardian Warm Roof. It helps homeowners increase their available room space and stands out due to exceptional design, with great styling and contouring of the roof.

Victorian: The Victorian tiled conservatory roof is another fabulous, classic shape that adds distinction to any home. It provides more flexibility regarding door positions and being a three facet design offers an attractive alternative shape to the Edwardian.

Porch: The Guardian Porch helps create additional space at the front of your home, as opposed to conservatory and replacement conservatory roofing. It’s extra security being another barrier and adds extra value to your property.


A Guardian Warm Roof is available in different tile styles and colours:



Metrotile: Perfect as a replacement for an old conservatory roof. The Metrotile shingle has many qualities in both appearance and performance. The colour choices available mean that Metrotiles can match or compliment virtually any UK house style. Metrotiles come with a 40 Year weatherproof guarantee and require no maintenance.

Guardian Roof Slate: A unique and full guaranteed slate which has been fully tested and approved. Designed and manufactured by Guardian, the slate has been specifically created for the Guardian Warm Roof system. Unlike natural slate, it won’t break or crack and it doesn’t become brittle or dangerously sharp.

Satisfied Customers

"I asked 5 company’s for quotes to fit a new back door and supply and fit a conservatory, Glevum were the only company to provide a quote. They have turned up on every occasion when they said they would and communicated well to confirm times. A very professional service throughout."

R Wilks (Cheltenham) - Apr'22

"Each aspect of Glevum’s service was very professional, from start to finish. From the initial visit to provide a quotation, followed by the surveyor, and finally the fitter. Like most people I was a little worried about the disruption of installation, but the fitter worked quietly and efficiently, problem solving along the way, tidied up at the end, and I am extremely pleased with the end result. Would highly recommend."

J Basden (Coleford) - Mar'22

"Very Accommodating initial contact in November and Glevum agreed to delay installation until the New Year. Good advice, very expertly measured up, even the large windows fitted within a few mm. The installation team worked through one of the gales and only returned for a couple of hours over the three days allocated to finish outside trim on four windows (out of 12). We are very pleased with the outcome..."

A Crowther (Cheltenham) - Feb'22

"I am very happy from start to finish with Glevum and would not consider going anywhere else for windows and doors and I would highly recommend."
