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

"We are new to the area and so needed to find a new company to install our new bi-fold doors. The website was clear and easy to navigate. And it was easy to get someone out to see us for a chat and to make sure we could do what we wanted."

K Jemma (Lydbrook) - June'21

"Efficient, friendly. This is the third time I have had windows fitted by Glevum."

K Lindesay (Cirencester) - May'21

"Brilliant start to finish with just one or two hiccups but these were resolved with very personal service. The issues we had were outside Glevums control and they worked with us to resolve them."

H English (Caldicot) - May'21

"The whole experience was far less stressful than we anticipated. The Team (Gavin and Luke) worked efficiently, quickly and were careful to maintain the COVID precautions. We were impressed with their professionalism and the speed at which they completed the job. Basically, an excellent service which we can happily recommend to our friends!"

T Robson (Gloucester) - April'21

"The whole process from start to finish has been so much more straightforward and efficient than I was expecting. Top class company and I am delighted with the quality of the windows, workmanship and care and attention to making it all happen so smoothly. Wish we had got the windows changed years ago!"

H Saunders (Gloucester) - April'21

"From my initial enquiry to the first visit by Mr Rose all was carried out extremely promptly & professionally... Matt & Scott have done a super job and I am very pleased with how my new bay windows look. I would not hesitate to recommend GLEVUM."

B Pickstock (Cheltenham) - March'21

"Excellent - very professional and courteous. The work was carried out to a very high standard. They kept all surrounding area covered to minimise dust etc. We had a couple of hiccups but they were rectified immediately and the after care cannot be faulted. Timing keeping was spot on. I would definitely use them again and would not hesitate to recommend to others."
