Replacement Conservatory Roofs Liverpool

Celsius Solid Conservatory Roofs Near me

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.

These are just a few of the benefits:

  • Surprisingly quick install time means your home isn’t exposed
  • Great value for money
  • Updates the look of your conservatory
  • No condensation build-up
  • Environmentally-friendly materials and construction

What makes Celsius solid roofs different?

These conservatory replacement roofs are made from Structured Insulated panels without the aluminium framework that most other conservatories have. The ridge and hip covers are made from 100% recycled polypropylene and don’t need battening down. The Kingspan TEK Building System Panels are made from timber and interlock together for a strong, insulated structure; they are then connected with Rapierstar stainless steel fittings, and insulated with Synseal Envirotiles, which come in a range of colours. Our retrofit roofs are also perfect for Velux windows, allowing you to let a little more light in!

Standard PVC-u guttering and fascia fit onto the outside of our Solid Roofs, and can even be supplied as part of the kit.

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.

A Celsius Solid Roof is a fantastic idea if you want:

  • To get year-round use from your conservatory
  • To save money on energy bills
  • A strong, long-lasting structure

    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 can Allerton Windows transform my home's appearance?
    • 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.

    Guardian Warm Roof System Explained


    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. All the options were explained and there were no hidden costs. We were provided with a start date and they arrived the day before to check there were no access issues. They began work on 05/11/19 and finished on 04/12/19, every day we were informed what would be happening the day after. We were so impressed, all the workers were helpful and answered any questions. 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. Whole house done in under 2 days with a minimum of fuss or mess. 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. They were excellent and searched tirelessly to find a glass company that would make the glazed units that we required which were 4 metres long. They even managed to fit the Glass roof a week earlier than first estimated as they knew we were in a mad rush to get into our new house as my wife is 37 weeks pregnant. 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.
