Changing the roof on the conservatory

To all experts out there, need a bit of advice.

We are looking to buy a house but we were told that the conservatory needs some work
I've attached 4 pictures on how does it look like.

Apparently, there's moist (Conservatory 2.jpg) along the wooden beam coming down from the conservatory roof?

Also does anyone know what is this white metal frame (Conservatory 1.jpg) on the ceiling of the conservatory?
Looks quite mouldy and damp.

We were thinking of replacing the roof and hopefully leave the beams alone.
The beams probably needs a bit of coating to get it back to life again.

Is that do-able?
If so, how much would it cost to get it done down South?

Thanks in advance for your help!

Anyone can help with this?
If there's not enough picture to describe the problem, let me know what it needs.
I'm going to view the house again on Sat.

The white frame is to stop cats/birds/people getting in through the skylight ( or getting out!). Its just like one I knew in Streatham, all Wickes bits. From you pics it looks OK to me. The problem is that the conservatory is colder then the house, but not vented. So every time you open the kitchen door, a puff of warm moist air comes out and the water content ends up on the conservatory roof. A better roof would help, though expensive. A nafty way of solving the dribbles would be to space the roof 6mm of all the cross beams and the one across the front. If you put a suitable flashing on the bottom beam, sort of a 4mm upstand on the inside of the beam then a 50 mm drip slope on the outside and fill the gap with foam. The water drips hopefully will stick to the roof and run down until it hits the foam at the bottom. When the foam is saturated the drips fall to the outside. its fiddley but doable and quick and cheap!!!

Ah right. I did wonder whether it was that but I was thinking, surely not?

You got it spot on that the conservatory is colder than the house.
Unfortunately there's no radiator fitted in there.

Ah OK.
Although I'm still getting my head around your "nafty" solution.

Do you know roughly how much it would cost?

That solution blew my brain's fuse.

LOL. I must be typing out loud without thinking it through.

I have a similar "sun room " and got a price for replacing polycarb with glass and that was c.£3k I fixed the leaking polycarb . That's a very low pitch you have - lower angle than mine ! If the roof structure was strengthened you could probably cover it with ply and felt it . I might do mine one day. PS I'm in Sussex, sort of down south

That structure looks strong enough to replace the poly with glass or put a proper aluminium/glass roof on it. Do that and you wouldn't need to get the council involved with building regs.

If you put a 'solid' roof on, no matter what it's made of, you need to get building control in who will want to make sure it's not going to fall down on your guests when you're having your canapes and fizz.

You can get quotes for glass all over the web, hundred quid a square meter is more than enough to budget for. If you get a new lean-to aluminium framed roof direct from the manufacturer then that's about £125 sqm unglazed list price. Fancier roofs (eg Ultraframe LivinRoof) might run £350 sqm list including glass/solid panels but you'll have to add for plasterer/sparkie etc. As these are 'solid' then you'll have to get building control involved but the roofs themselves are "pre-approved" for all loading. You'll just have to show the walls can hold the roof up, and the foundations can hold the walls up. Livinroofs are insulated to current standards and can be put on a normal extension.

Putting a modern made-to-measure roof on is a weekend job for two people who know what they're doing and can be done by a handy DIY'er. The profit margin on putting a roof on is huge, you can easily be quoted £10k for a new roof that costs £3500 to buy with a decent discount and costs £1500 in labour to fit/finish.

Thanks guys for the advice.
Will look into it.
