You may well have seen all the advertisiments offering different ways of achieving a solid roof on your conservatory, many different companies offer different solutions to conservatory roof replacement, some good and some not so good. So how do you know which type of roof you should have installed on your conservatory?

As specialists in conservatory roof replacement throughout the whole of Cornwall & Devon we know the difference between a good glazed and solid conservatory roof and the not so good. We know all the important things that homeowners looking for replacement conservatory roofs or new conservatories need to be asking about before purchasing.

1. Solid Conservatory Roof for New‐build or Refurbishment?

Most of the replacement conservatory roof systems manufactured by reputable companies have been designed and engineered to be lightweight, this means that most solid conservatory roof systems are suitable for installation on to existing conservatory window and door frames. Solid conservatory roofs are suited to both existing conservatories and new builds.

Often referred to as a ‘retrofit’ in the industry, homeowners in Cornwall and Devon are choosing to retrofit solid conservatory roofs in order to transform old conservatories that are too cold in the winter and too hot in the summer into living spaces that can be used the whole year round, no matter what the season.

When looking to build a brand‐new conservatory with a solid roof, you will need a company like Best Glaze that can build everything, from the base and the walls to fitting the window frames and of course installing the solid roof.
We recommend using Durabase for the base and the walls, its a modern method of building conservatory or extension bases, its much faster than older building methods, cleaner because there are no footings to dig out and becuase there are no messy footings to dig, no services or drains need to be moved.

2. Planning Permission and Building Regulations for Conservatories

Most new‐build conservatories with a glazed roof, solid roof or tiled conservatory roof will not need planning permission, they are usually fall into the catergory of a ‘permitted development’. There aresome limits and conditions pertaining to the placement and size of the conservatory, which you can find details of on the Government’s Planning Portal.

Building Regulations almost certainly apply if you are going to build an extension on your home, but not for a conservatory, if certain conditions are met. So that your conservatory is classed as a conservatory and not an extension, it will need to meet these following building regulations requirements:

The conservatory will need to be separated from the main house with external quality walls and/or windows and doors that meet Building Regulation requirements.
The conservatory will need to an independent heating system that has on/off and temperature controls seperate from the main house’s heating system.

If any of the above measures are not adhered to, the conservatory is classed as an extension of the exisitng home, in which case separate Building Regulations will apply. The work done on the conservatory such as windows and glazing and electrical work will have to adhere to specific Building Regulations. More details about solid conservatory roof projects is available on the Planning Portal.

3. Is your Installer Certified?

It is not a legal requirment for someone to be certified to be able to carry out work such as conservatory roof replacements. Not all building work carried out by builders, installers and contractors is certified as certification with governing bodies is volunatary. Installation companies usually choose to register with Fensa or another government approved certification scheme. Nobody wants a ‘cowboy builder’ look for trusted, reliable tradesmen they usually have the best standards of workmanship.

4. Insulation and Energy Efficiency What To Look For?

One of the selling points of a good quality replacement conservatory roof is the insulation & energy efficiency levels. Do a comparison on solid roofs to check for the ‘U-value’ this will inform you of the energy efficiency of any tiled roofs you may be considering.

What is a U‐Value?

‘U’ values measure how effective a building material performs as a thermal insulator. So thermal efficiency is actually measured by how much heat is lost through the building material. The lower the ‘U’ value the greater the performance in terms of how much energy is required to maintain a comfortable temperature within a property.
The lower the U‐Value = The lower heat loss = low U‐Values equal good energy efficiency.

Ideally, when looking for a solid conservatory roof replacement, you should be looking for U‐Values which are below 1.0 W/m2K. Any roof in this range will have very good insulation and therefore be very energy efficient, Keeping your conservatory warm in the winter by retianing heat and cooler in the summer by keeping the heat out.

5. Can you Fit a New Roof to your Old Conservatory Frames?
