Too hot in summer. Freezing in winter. For many homeowners, conservatories have become an annoyance — prone to leaks, uncomfortable year-round, and often used as little more than a storage room.
At Onyx Roofing, we replace outdated glass and polycarbonate roofs with fully insulated warm roof systems that turn your conservatory into a comfortable, maintenance-free, energy-efficient and thermally regulated living space you can enjoy all year round.
Whether you’re creating a dining room, home office, playroom or extra lounge, our warm roofs are designed to maximize comfort, significantly reduce heat loss, save on energy bills and add value to your home.
A conservatory warm roof is only as good as the team installing it.
At Onyx Roofing, every roof is custom built on site to your conservatories exact dimensions. We don’t use low quality one-size-fits-all systems or cut corners.
From the structural framework to the final light-weight tile, our focus is on quality workmanship, long-term performance and a finish that’ll last a lifetime.
We combine high-quality materials, expert installation and thoughtful design to transform your conservatory into a comfortable, energy-efficient living space you can enjoy all year round.
Fully insulated to keep heat in during winter and out in summer.

We put out an enquiry as we had been badly let down by a previous roofer. James contacted us and came that day. He was charming, knowledgeable and reassuring. He started within two days, his work was exemplary - with a great attention to detail - and great value for money. James noticed a few little niggly problems and went above and beyond to fix those too. Wish we had contacted him first. Would thoroughly recommend him.Posted on Google![]()

This company is definitely trustworthy, I had them to do a full roof for me plus all faschias and gutters and had no problems at all, turned up on time every day, whatever the weather, cleaned up after themselves every day and were honestly the most politest and respectful lads you could wish for and also gave us the best quote, not necessarily the cheapest but we certainly were not ripped off! credit where it's due!

In most cases, replacing a conservatory roof with a warm roof does not require planning permission. However, building regulations or specific property restrictions may apply depending on your home and the type of conversion. We’ll be happy to advise you on any requirements.
A conservatory warm roof is a fully insulated, lightweight, solid roof replacement designed to replace an existing glass or polycarbonate roof. It helps regulate the temperature inside your conservatory, keeping it warmer in winter and cooler in summer, while improving energy efficiency, comfort, home value and overall appearance.
Most conservatory warm roof installations are completed within 3 days, depending on the size and complexity of the project. Before work begins, we’ll provide a clear installation schedule and keep you informed throughout the process to ensure everything runs smoothly.
The cost of a conservatory warm roof depends on several factors, including the size and style of your conservatory, your choice of roof finish, and any optional features such as roof windows or spotlights.
