Conservatory Roofs

Thanks Richard that is really useful, do you find it is also a bit cooler in the Summer?Sounds exactly what we want to maximise use all year round.

When we re-built our house three years ago, our builders installed an insulated roof on the conservatory in much the same way as Richard Pitman describes.  3x2 battens bolted to either side of the aluminium roof framework and then felted and tiled using Marley composite tiles that look just like slate but without the weight.  The inside of the roof  - between the tiles and the plasterboard ceiling was then insulated using Rockwool and that 'space blanket' material and the room has been transformed.  It's now part of the house, rather than just being 'stuck on' and is cool in summer and warm in winter and no noise when it rains.  I can't be certain as to cost because it was included in all the other works but I believe the builder allowed about £2000 for the job.  It really was very straighforward and was completed in a couple of days.  Our Building Inspector arrived just after it had been completed - at a time in October when we had no heating (that was another part of the work) and immediately commented on how the temperature of the house had improved dramatically.

Picture above says it all really. 45x95 treated C16 timber joists, sitting on top of existing aluminium joists, strong enough for me to walk on, although I did prop it from below, just in case.

Small roof light was replaced with a larger Velux, and proper guttering fitted at eaves.

Main reason for doing this was to reduce heat in summer. I'd already fitted an extra layer of opaque white polycarbonate sheeting, multichambered 50mm thick, internally, and this makes an acceptable ceiling, didn't bother with plaster boarding it.

As I seem to got the hang again of posting pictures, here's the finished job. I secured the wooden joists to the aluminium frame using 150mm stainless self drilling screws from Screwfix. Entire job only cost a few hundred quid, these firms that charged 10K or more must be laughing all the way to the bank.

And the roof is now fully waterproof, used to leak in heavy rain and strong winds.

Nice job, Richard......you should take it up for a living!

Looks very smart. The downside is the reduction in light in the house though.

Thanks Richard great pics just what we want to do....not expecting major lack of light CY our conservatory is 18ft X 10ft so plenty of light flooding in beyond the roof.

TOPman Richard i love to see anyone get stuck in to diy and what agood job to you have given me the push i needed to do ours bet i do it this sumer thanks  Alan
