Celsius Solid Conservatory Roofs

We are proud to fit Celsius solid roofs to conservatories in Liverpool, which can be retrofitted onto existing conservatories – making them warmer, more environmentally friendly, and more economical.

A Celsius Solid Roof is a fantastic idea if you want to get year-round use from your conservatory, save money on energy bills and ensure a strong, long-lasting structure.

Each roof is bespoke and delivered in an easy-to-assemble kit, meaning less time spent on labour and less disruption to the household.

The interior roof will also look beautiful, with a plaster-boarded internal finish and a choice of either a ridge apex or orangery-style pelmets for the perimeter. This allows you to incorporate downlights or a speaker system.

We have recently had a replacement Guardian Solid Roof System installed on our existing conservatory by Allerton Windows. We are extremely happy with the finished job and could recommend the company. Many thanks to Tony and the team from Allerton Windows.

After having several companies quote for our extension we went with Allerton due to the amount of positive reviews and the person's knowledge and honesty. I can’t fault them and would highly recommend them. Thank you.

I spent a while looking for prices and Allerton windows were the most competitive I could find. The person I dealt with was really helpful with advice on what was available and the fitters themselves were gents. Will definitely be using them again for future work. Thanks lads!!!

Allerton Windows did an amazing job for us on our Aluminium lean-to roof. We were told by numerous different companies that we could not have what we wanted until we got in touch with Allerton Windows. We will definitely be using Allerton Windows again in the future couldn't be more happy with the service and our glass roof looks amazing.

How Our

Roof Replacements Work

Allerton Windows has over 25 years of experience improving homes and fitting replacement conservatory roofs in Liverpool.

At our showroom in Bootle, we can show our complete range of all our roofline products, so that you can find the design that best suits your home.

  • How do replacement conservatory roofs improve a home?
  • Our UPVC technicians will be able to transform your home appearance by installing a full specification roof line. Our hard-wearing and low-maintenance materials will play an essential role in preventing damp getting into your home.

  • What are your thoughts on using a cover board?
  • We often see customers wanting to opt for using cover board. This is not best practice as if their rotten timbers are covered up this does not mean they will not still deteriorate. This will leave all roof line insecure.

  • Why choose UPVC against original timber fascia and soffit?
  • When looking at any property first impressions count. Looking at the front elevation people will look at windows, doors and the roof line. With UPVC there is virtually no maintenance apart from cleaning out the gutters and wiping down the fascia and soffit.

Types of

Conservatory Roofs

  • Edwardian-Roofs


    The Edwardian style of conservatory roofs features a symmetrical shape and plain glass. They are less ornamental than Victorian-style conservatories and tend to maximize floor space in comparison. This unfussy style is suitable for a wide variety of conservatories and homes.

  • Lean-to Conservatory Roof


    A simple lean-to-conservatory roof maximizes space at the rear of your home, without the need for extensive groundwork. These types of roofs are perfect for accompanying kitchen extensions and can go as low as s 15º with roof windows.

  • Victorian Conservatory Roof


    Victorian conservatory roofs are a great choice for those who are limited by the space they have in their garden. Typical features include a steeply-pitched roof and a bay front. They may also feature more gothic shapes and details.

  • Gable-ended Conservatory Roof


    Conservatories with this type of roof feature a generous interior space thanks to its continuous height and gable-ended main feature. This allows you to benefit from more light and space, making it a more enjoyable space all around.
