Polycarbonate Conservatory Roof Replacement
Discussion
Just had a quote to pull out the polycarbonate roof panels, retain the original aluminium roof frame and fit one of the roofing systems. Basically, simulated roof tiles over a wooden and insulated roof. The inside would be plaster boarded and then skimmed. lots of companies appertains to be offering this service or similar.
Would appreciated information from anybody who has had it done.
Cheers

We've had a insulated roof with plastic tiles put on our conservatory.
Old roof removed completely, timber frame, insulated, osb and plastic tiles on top.
A good carpenter/roofer will be able to do it for you. I looked a some of the window companies first and let's say there is still alot of profit selling the roofing systems.

Yes, i go that impression. I'm inclined to contact the roofer who did our main house roof a couple of years ago. It doesn't look like rocket science.Old roof removed completely, timber frame, insulated, osb and plastic tiles on top.

They want to use your existing glazing bars as the structural support for a new roof, plus plasterboard ? 
s. The biggest consideration when doing these, is will the additional load flex the vertical frame and cause window/door openings to jamb. That’s without taking the forces of wind uplift into account which could pull the lot off in a single gust.
It’s a murky area occupied by double glazing salesmen. Tread carefully.

Read THIS, and make sure that any system you fit has an Agrement Certificate, and preferably an LABC national type approval.V8 Animal said:
Get planning approved before you do it as it will be classed as a extension.
Unlike Building Regulations, conservatories have no special status under Planning - so the original conservatory will have either been exempt due to size rules under normal PD rights for extensions, or it will have required Planning Permission as normal.Unless special circumstances apply, the change of roof covering should be Permitted Development under Class C of domestic Permitted Development rights, which unlike Class A (extensions) do not include a stipulation that materials must match existing.

Advice taken on board. The industry does have the feel of the 1980s double glazing boom. s.

In fairness to the company that quoted, the guy did advise an additional wooden structure would be fitted as well as the existing glazing bars. This would be checked by a Structural Engineer. He also checked that the windows had metal frames. All would get buildings approval.
I had my roof converted 5 years ago. I'm very pleased with it.
I have used the same fitter many times on my own home and my rentals.
He removed the original glazing bars and fitted a new metal ring beam over the top of the windows and bolted up through into the beam and bolted the beam to the house.
A new roof was then built up from the ring beam using metal and wood.
We use the space every day, summer and winter. The original patio door somehow fell out during the construction and I really should replace it!

Carry on replace roof then sell your house and wait and see.
We had one of these roof systems fitted to our conservatory about 6 years ago, it was done by a well regarded company here in Tyneside, its was quite expensive but done to a very high standard. We got lots of quotes, some very cheap and obvious why (they were a cheap and not so cheerful alternative) and some very expensive from the 'big' double glazing firms in the area. In the end we settled for the one we went for based on service and reviews. I het the impression these systems are way cheaper these days and I'd say they are well worth it.
The only negative is that they are advertised as making th conservatory like a normal room... thats not quite 100% true, yest ours is VERY GOOD but in the winter its still colder than the rest of the house by a couple of degrees but in the summer it is fine, not the hot house/green house it used to be.
My advice, by from the better end of the market on quality rather than price.

Timely thread... We've just had a couple of quotes to do just this on our 5.5 x 3.5m conservatory and were stunned at the cost.
To replace the existing glass with insulated panels, no plastering, £7k.
To replace with a full Leka roof system, plastered inside etc.... £18k.
The chap who quoted did the conservatory originally and is highly recommended, but we were taken aback.
We're now getting quotes from builders to change the space properly into a room, go through BC, get drawings done etc

In fairness, I deal with this sort of stuff for a living.There's always some bar-room expert who thinks he knows better, though.

Having said that, not everyone else does.
As V8 says when you sell a house the solicitor ask if you have made any changes and expect a certificate or indemnity, regardless of whether the regs actually require it....

When I had my roof converted by Cosy Roofs I was asked at the time if I wanted to pay the fee for council approval they come out and check etc.
I declined but when I came to sell my house had a lot of hassle having to sort this out myself with the council, cost me more in the end.
Pay the fee about £100 I think, unless this has now changed this was in derby 2 years ago maybe I was unlucky with the comments on this thread?
Still a good idea though, never have a glass/ poly roof again.
Cheers

Then the correct process would be to obtain a Certificate of Lawfulness.It is actually not lawful for a Local Authority to grant Planning Permission on work that is Permitted Development.
I’m actually having my conservatory roof replaced with one of these systems (Guardian Warmroof) in the next couple of weeks. I ordered it back in May and it is just coming through now.
They remove the existing roof completely and replace it. The new one is insulated and plastered out etc. I had a look at various offers and I don’t remember any that wanted to retain or reuse and part of the existing roof, so I’d be wary of that.
My conservatory is 4 x 3ish and the job is coming in at just over £10k. It can’t come soon enough - it’s been an absolute inferno in there the last couple of days.

Things always cost more than I imagine, and I'm sure it's value to you to gain a useable room. They remove the existing roof completely and replace it.

But that does seem an awful lot for a roof.
