Which Tiled Conservatory Roof Conversion Is Right For Me?
A tiled conservatory roof to replace the existing roof is a very popular and functional improvement right now, it ends the decades of infrequent use that conservatories have become renowned for.
The addition of a solid roof and insulated ceiling to a conservatory enables the space to be used much more frequently and has the potential to be decorated and furnished much like a room in the home.
As with most things, there are options available and the narrative below is intended only as advice and is what I would expect you to receive from other sources. This advice is not an exhaustive list either, there will be additional points and exceptions to consider prior to making your decision.

A tiled conservatory roof is achieved by replacing or removing certain parts of your conservatory roof. Two of the common methods is to convert your existing roof frame or replace the frame completely and install a new one.
Using your existing frame to build onto and underneath the frame with the materials is a perfectly acceptable method of carrying out the work but certain factors should be considered first, such as roof condition and pitch, style and age, the span of the roof, the structural rigidity of the conservatory and the presence of brickwork relative to framework and glass. There are limitations to the level of insulation used too with a conversion because the height of the existing roof bars determines the available space for rigid PIR insulation, like Celotex.
An example of an unsuitable application of converting the roof would be a Lean-to conservatory that was 6m wide x 3m projection with roof pitch less than 14 degrees and constructed from full height glass panels, the minimal framework with no supporting brickwork or foundations.
An Edwardian style roof that measured the 3m width and 3m projection on a conservatory built with 600mm high double cavity dwarf walls and half height frames and glazing would be suitable if the conservatory and roof frame were structurally sound.

There will be other instances where the conservatory may or may not be suitable though and these are just two examples. A reputable advisor should bring these to your attention.
A converted roof relies on the roof frame being fixed correctly, in good condition and a conventional style where structural strength was considered at the point of manufacture. Of course, there may be hidden defects within that frame that aren’t immediately apparent and that could be an issue further down the line.
A replacement tiled conservatory roof for your conservatory is the other option. In component form, it uses the same materials as a converted roof with exception of the roof frame and additional insulation but again, sometimes it’s not a suitable application if the existing conservatory isn’t strong enough to sustain the extra weight.
Installing a new roof has benefits. You could change the roof style from an Edwardian to a Georgian for example. A new roof creates all new fixing points on the house wall and can be strengthened further without obstructing the material components at the point of fitting. A replacement roof allows further insulation opportunities and of course, the lifespan of the roof starts from the point of installation.

With a new roof though comes a new ring beam (the material between the top of windows and roof), this means the old one needs to be removed and this could make the window frames lose some integrity and may not re-seal as well as they were prior to the ring beam removal. An installer should check for this though during the installation.
Install time could be disrupted if the weather is unkind and the level of decoration within the conservatory may become damaged if subjected to damp weather. Should you opt for a prefabricated aluminum roof and there have been mistakes made at the point of measuring, it could mean a conservatory without a roof for longer than was planned. A timber roof could be amended on site.
There are pro’s and con’s to both options when all things are considered equally. It is worth noting that both options can get building control approval and both can be covered by a 10-year insurance backed guarantee.
Once the considerations above have been factored into your situation and conservatory, then it becomes a decision based on your preference.
