Bespoke Conservatories - Roofing Options
As you imagine yourself relaxing in your bespoke conservatory, remember that you can enjoy perfect comfortable temperatures all year round. In fact, your dream conservatory will be the most temperate room in the house.

You may opt for solar glass roof that reduce heat loss in the winter and prevent heat build-up in the summer affording perfect temperatures all year round.
Or you may opt for our polycarbonate roofing. This advanced roofing material is able to reflect 80% of the sun’s incident radiation so it doesn’t enter your bespoke conservatory through the roof, keeping your room cool in the summer. It also reduces glare which means it creates, soft ambient lighting. In addition polycarbonate roofing radiates rising heat in the winter and pushes it back into the room so you stay warm and cosy.
Remember also that all our roof materials are manufactured to the highest standards and John Williams’s roofs are guaranteed for 10 years.
