This could be stupid, but, I have a question about my Marley garage. In case you don't know what I'm talking about it is a concrete panel bolt together unit with a sloping roof on top. Cheap and cheerful. It is structurally sound.

It's a double garage so plenty of room for my bikes and workshop and toilet but it is a little bit of a low ceiling height and I want something just a little bit higher, perhaps to give me a bit of storage space for odds and ends in the rafters.

OK my daft question, do you reckon it's possible to remove the sloping roof panels and construct an apex type roof to go on top of the existing panels.

The sloping roof is held by metal support beams, that themselves are simply placed on top of the outer panels. So how about a raised structure, a timber frame or something going around the perimeter with a roof on top.

I'm only thinking of raising it about 18/24 inches or so around and then an apex maybe 4 feet higher in the middle.

Stupid, or possible?

In a word no Si, so you would need to get some trusses made up, my last garage used 1"x1" angle iron welded and cross braced, spaced about 2 feet apart.

Never say no that was my motto. All things are possible si. If you had loads of time you could strip the existing roof of
jack the walls up by the required height put six or eight coarse of bricks round then sit the panels back down to give extra height  put a timber plate strapped to the top of the walls. Get trusses made as these would be a lot lighter than a cut roof felt batten and tile jobs a good en easy as that init.[biggrin]

I was thinking just now while out walking Molly in the snow. Can't I just put on a wall plate and then build trusses to go on top of that?

That way the plate would add 4/5 inches, then the added truss sizes maybe another 4/5 inches at the edges, and the pitch of the truss maybe another 18inches in the middle. I'd settle for that little extra.

The existing roof bearers are a [ beam shape and could be left for structural strength as they only intrude slightly.

I'd prefer some assurance from someone who knows, if I'm thinking something sensible for a change.

My lad is a chippie on new builds and refurbs, I'd get him to make some wood trusses like a proper roof

Do you need extra height at the side too Simon? if not just go with trusses, you don't want to go more than about 600mm from the top of the wall though, the problem as I see it will be stability in high winds, if you add to the wall, and then add trusses I think you may have problems.

I assumed the trusses need to bolt to something, much like when we built an extension which was brick walls, then a plate, then trusses.

Built proper darn good too it was. My better half built it all in her own. As project manager and contractor. She even convinced a proper architect at a proper builder to visit, design it and then submit for planning consent all for £50. He was a friend of the family. Bruv in law dug footings (we had terrible problems) 2 cousins did the brickwork. Friend did the plastering. bruv in law's bruv in law did all the wood working. 2 friends of my lad did the roofing. Another friend did the electrics. Another plumbed in the radiator. Another bruv in law of a bruv in law laid the carpets, a chap across the road worked for Hillarys Blinds did them and the double doors and windows. Joe Muggins had to wield a paintbrush and also lay the insulation in the attic of the pitched roof (all done proper like ). Oh, and she also convinced BuildBase to open an account and give her trade price on all the materials.

When the footings were dug down the correct distance and we called in the council chap for approval to go further. He didn't like a soft spot in the middle and we had to did it down, and down, and down, and down. Then he came back and dp said he'd looked on some old plans and found a sewer pipe running where we were digging. He insisted it was found.

It was found, finally about 8 feet down and going away under our house foundations. It was cracked!

So we wire brushed it clean and invited him back to see it and tell us what to do next. He looked down the hole, looked at the ladder placed for him to go down, and simply said it's fine, fill it in and shield the pipe with pea gravel.

That cracked pipe is now well shielded under 15 tonnes of concrete!

Not sure I'd bother with a wall plate unless it helps with the height, just more work and expense, bolt trusses direct to the wall panels,

We had similar issues with the houses extension,

hi

if it was mine i would look at jacking it all up and building a concrete block wall under it and then lowering it down again

you can hire things called toe jacks and jack it up a bit at a time


years ago i did this to a house that had the outer wall built really badly and needed the roof supporting so that the walls could be knocked down and re built

Yep, now you can't even change a lightbulb unless you are a 'competent person' with suitable accreditation - which precludes retired folk with a lifetime working experience of doing just that as your 'competency' ends on retirement.

Okay, I exaggerate, but now you can't run a even a simple circuit without building control approval - oh, and permission costs only £240 in my neck of the woods for that.

You are allowed to do your own electrics just when you sell up  get a sparky to part p it and sign it of
providing its been done correctly its not a problem.  Only problem is its expensive round here they charge anything from
£250 up because they know you don't have a choice.

I think it was about 4 years ago but not sure. Same sort of thing with gas I can do the pipework and connect it all up
but then have to get a gas safe guy to test and sign it of. Just another money spinner although I agree if its just a diy'er

doing it then it needs to be checked and certified as safe for everyone's benefit.
