As an update to this thread, I though I would just add some useful info about this roofing system. I won't describe the structural make up of the roof because it’s available on the internet.
However I will give the details of my own new roof.
I have a conservatory which is around 5 x 5 metres, which I guess is a good size, and its called a P shape. It had a polycarb. roof and the roof had been in place for about 8 years, and was showing signs of wear and had a small leak.
I'm not a fan of polycarb and the roof was already in place when we bought the house.
I looked at a number of options before deciding on the Guardian roof such as double and triple glazed.
The quotes ranged from 6 to 9 k for glass.
I opted for the Guardian roof simply for the year round use it offered.
The price was 10k which included all fitting and plastering of the new ceiling. I opted for the galvanised tiles rather than the plastic which were a higher cost. The cost also included additional work such as wiring and adjusting existing doors and windows so they closed better. Therefore without this extra work it would have been a bit cheaper.
So what difference has it made?
Well firstly its expensive, secondly it’s great and I am pleased we did it.
The room is now warm and dry and actually quite bright (once the ceiling had been painted white). I haven't noticed any reduction in light and this may be down to the polycarb being tinted.
The room is also a lot quieter and this is particularly noticeable because I have a cat that frequently jumps down from the higher roof on to the polycarb roof with such a bang it scares the crap out of me. We don't hear her now. (worth 10k just for that as I'm getting older and more prone to heart attacks).
Therefore if you can afford it get it done, I now have a permanent extra room on the house that’s warm and useable all year round.
