Raising the (workshop) roof?

In message , T i m writes

Probably a fairly major undertaking if you are not familiar with them, but quite doable

What make is it ?

e.g. Banbury and Compton use quite different construction techniques

You would Have to renew the roofing sheets, the old ones will probably be very brittle, the holes not in the correct place and, yes, too short

Screws and clips will probably be well rusted as well

Is the front gable not concrete? You would have to remake F & B out of wood

Well I was with the guys when they assembled it and it all looked fairly straight forward (luckily I had provided them a very flat / true base to work from and they seemed grateful for that (that and plenty of tea and a Pizza for lunch ). I had them assemble it rather than doing it myself as I wouldn't have been covered for any panels / sheets that broke during construction etc. Plus, it would have been a pretty heavy job (8' eves).

Sturdy I think Geoff (it was about 15 years ago now).

Possibly. The bits inside still look ok.

Tongue / groove wood. I was thinking of replacing them with waterproof ply (noise / insulation), skinned with gavl steel (for some security) and plastic cladding (for looks).

My outstanding question is still the ridge pieces. The existing ones [1] are set at a fairly shallow angle and I don't know if there are others of greater angles or if you imply use a different technique (like a traditional clay ridge tile bedded on cement)?

All the best ..

A level base is absolutely critical for a good construction

That said, we built some where the front posts were on two bricks (having a) got a waiver and b) a bit of extra in the back pocket for the extra work

Prolly sensible, they would know how to go about it and know the work arounds when a problem came up

It's all technique, two of us would put up three in a day

Not one I know

I was going to mention that, then the wife came back from her dance class, ... and I forgot

the best workaround I could think of would be to pack the space out with a mortar fillet

Wow.

I think these are them Geoff ..

Doh!

Ok, so I have this straight (and this might account for the lack of replies) ...

On my existing garage roof the ridge tile (as you would call it on a tile / slate / roof / hip) is actually moulded out of the same cement fibre as the roof sheets. It covers the width of a ridge tile and a good 12" either side of the roof (like a sombrero) and is set at the same angle as the pitched roof. It is bolted down in the same way the roofing panels are.

I was assuming these might be available in a range of angles but maybe that's not the case and if I was to move up to a steeper pitch I may have to go back to a more traditional mortar beded ridge tile of some sort (or I could use a hip tile if the angle wasn't that much)?

I must admit I like the existing setup as there is no mortar to apply and crack up.

Hmm, maybe I need to re-think this .. :-(

All the best ..

Same basic design as Compton

Why would they do more than one angle ?

I would think that they would have just one standard pitch of roof

you might find them at a building suppliers

I think it's the same basic design as many pre-fab garages Geoff but the bit that interested me was the especially tall eve height (more space for racking and motorbikes on lifts etc) ;-)

Because they often also do 'Deluxe garages with higher roof angles but they also seem to use either 'tile look' corrugated steel sheets [1] or real tiled / slated construction (and therefore using traditional building techniques).

I guess I could also use some sort of a galvanized metal ridge (do they make such a thing)?

All the best ..

You'd be surprised, there are a number of different constructions

The message from T i m contains these words:

Yes, of course they do. Bend to shape! :-)

Some asbestos-cement ridgings are actually made up of two overlapping pieces so will handle a wide range of angles.
