Hi. Last summer, a friend and I lowered our 16' x 9'carport roof
(supported on 4 - 4x4 posts) and moved it around to my backyard where it
now sits on a couple of beams supported 4 feet in the air by (outrigged) oil
drums. The move was relatively easy as it was gradually lowered onto an old
truck chassis and then towed around back by a farm tractor.
My guess is that the whole roof probably weighs about 1500 pounds.

I now want to build a support structure (joists, floor, walls) directly
under it
and somehow lift the roof up (joists, rafters, and roof deck including
cedar shakes) onto the new walls, sort of a reverse build if you will.

Anyone done this before?
What is a good safe and simple approach for lifting the roof with a new
floor
and wall structure under it?

It will need to go up another 6 feet in order to clear the top wall plates.
The use of any heavy equipment such as cranes, backhoes or
forklifts is ruled out as the access is limited and just not in the budget.

If needed I can email some pix of the project.

Thanks, Wayne

Just reverse engineer however you lowered it to begin with. Get it
higher than your proposed walls, prop there, build walls, lower roof.
Trying to build walls then lift the roof on top is the hard way at it.
At least that seems to be what you are proposing.

I did it to raise a bar joist/hot tar roof about 6'. Used rented
shoring scaffold, screwjacks pushing on stringers fastened to the
bottom of the bar joists.

Egad, I wish this Newsgroup would permit a small pix to illustrate my
dilema.
I understand and agree with what you're saying. Lifting the roof over
already-built and standing walls was not my intent. Sorry if it came over
that way.
However, the challenge remains in devising a safe way of actually getting
the roof _even higher_ than it is currently supported on the 4 corner oil
drums ..and doing it safely and inexpensively. I need a good simple method
here. Wayne

Thanks, Dan. I'll check our local rental outfit and see what they have to
offer for this application.
My concern with this method, however, is how to insert the wall structure
and upper plates with the scaffolding in place (covering the underside of
the roof joists)?
I am pondering the idea of first building the floor deck in place. Then
using that as a platform placing the scaffolding or other supports on that
and go from there ..with a myriad of bottle jacks ..or are there special
long-extension jacks available for just this purpose? This would leave the
outside perimeter of the roof/ceiling/joists for acceptance of the new
walls.

you might to try some jacks they have for pickup truck campers where you
would work them in pair lifting to the max then shimming the second. or the
lally column screw jacks they have for houses You want to make sure you
have good side to side stability. Don't rule out a small crane they crane
in hot tubs to back yards and decks all the time I think mine was leas than
500 bucks and it would be a lot quicker!

Thanks, Wayne. A crane would be nice, but ..nyet. You might have determined
from my original post that I would like to accomplish this on the relative
cheap. It will be afterall, only a shed and I have spent way too much on it
in both building materials and time already. Me thinks the cost of building
a new roof would be cheaper than hiring a crane. And building another roof
ain't gonna happen as that would probably tip the scales of cost/rewards.

Here's some more background: this whole exercise started when I wanted to
remove an unsightly carport and nobody needed one. I had the "bright idea"
to move it and frame it out into a shed or ?? So now it sits waiting for my
decision.
What I need is a nifty diy plan with supplies at hand.

Being a guy who has done all kind of things 'on the cheap' some that
worked, some that didn't, I don't think you will be able to accomplish
the mission. It is going to cost you money. You will have to rent
(or scrounge - not likely) the proper jacks, rent the scaffolding as
mentioned above, or at least scrounge a -lot- of dunnage.

As for building the walls with the roof above them: The procedure is
to raise the roof high enough to enable erecting the walls below them
then lowering the roof into place. It is possible to build the wall
into the roof while it is blocked up but it is a frustrating job,
basically you have to have your stringers supporting the roof
parrallel to, and a short distance away, from the wall you are
building.

Harry K

If you've got the space around it, and fairly deep soil with no
piping under it, you just stick a post near each corner, anchored with
cables, and hoist the thing. Use 4' long bits of #10 rebar as
stakes. If you haven't got the space for that, build a tripod
out of 10' galvanized pipe at each corner, and hoist the roof
on a pair of 16' 4x6s slung between them.

Jeez. The more I think about this task the more I'm beginning to wonder if
it really is worth the effort ..and $$. Salvaging the carport roof was
more of a recycling project that is turning into a new building but with the
added twist (and cost) of working with an old roof. How many people
construct a building around it's roof ..especially a 16x9 shed?
Perhaps I should really weigh whether it should just be deconstructed and
another built once the walls are up ..or factor all that into it and
postpone or even nix the project.
Another twist is the cost of the concrete for the footings/pads (already
cribbed) will be picked up by the municipality as they are repouring curbs
on our street later this week and will have extra left over for me. Nice
guys.
So, if anything the pads can be used elsewhere as HD stepping stones ;^\

After asking myself 'what would I do?' I did come up with a possible
cheap way. You would need several strong guys and a few helpers.
Prop it up as high as you can without going to excess, lay strong
timbers at a slant up to the new wall plates, levers, pushing,
grunting, blocking to keep it from sliding back down, etc. Maybe a
couple come alongs over the top of the walls to pull with. My motto
always was 'if I can move it an inch, I can move it a mile given
enough time'. It doesn't have to be done all in one day.

How about lifting it as high as you can (like I kind of remember it
already is sitting on steel barrels), and then lift one end up about 5
or 6 feet and build a temporary wall under it -- don't forget to add
diagonal braces! Jack the other end up to the desired 8 feet and build
a real wall under it -- don't forget the diagonal braces! Now jack the
first end up off the temporary wall, knock down the wall and build a
real wall. Frame the 2 sides and tie it all together and you're done.

Bob

Nice idea, Bob. However, the scary thing about that idea is having the 1500
pound load skidding out on me and collapsing to the ground, pinning me there
with blood rushing out of my mouth. And my wife doesn't get home until 5.
lol
Seems to me we would be talking about one end on the barrels (which could
present a stability problem when boosted even higher) and the other end
being elevated further. At some point -- not too far up -- the barrels
will become super unstable and slide out OR the other end will do the same.
Either way the force on either the barrels or the temp wall will be
exagerated. So it seems to me the angle ratio will be quite steep and I'll
bet some physics laws come into play here.

Further comments..?

Wayne


Actually, what I think I'll do is make another pix of the site and post it
to a link, then share this with you. A 'visual' may be a better demo of my
situation.

How about this; make a bunch of A-frames out of 12 foot or 14 foot 2x4's
bolted together with a single carriage bolts near the top. Suspend the
roof from the A-frames with short pieces of safety chain. Have some of
the frames going this way, and other's going that way. YOu don't want
the m parallel or they might tip over. You'll need some sober friends
to help you -- lift the thing a little at a time. Nail braces all over
the place to stabilize it.

I think you need to sit back and consider two things:

- does the roof meet your requirements? Or should you abandon
it and start over?

- if it does, it will be _extremely_ unlikely for you to be able
to jury-rig _anything_ to hoist the roof cheaper than a 1-2 hour
visit by a crane.

Heck, even if building "tripods" of 2x4s or steel pipe, or any of the other
ideas I've seen proposed here would work at all, I don't give two bits for
their safety. I'm convinced that it'd be cheaper to hire a crane than
try cobbling together tripods (the pipe isn't free either) or even
renting scaffolding.

A heck of a lot safer too.

In the scheme of things, 1500 pounds isn't that much. A delivery truck
crane (ie: those used for delivering shingles) could handle it.

The cranes they use for erecting trusses should be able to handle it too,
and they're cheap for short jobs.

It's not just anyone who gets a Starship Cruiser class named after them.

Thanks, Chris. But as I indicated at the beginning, I can no longer get any
heavy equipment to the site. So I am left with doing this chore by hand.
Having a crane at the front of the house and maneuvouring it over to the
rear is far too expensive for something that was supposed to be a lowly
salvage/recycle operation.

added twist (and cost) of working with an old roof. How many people
construct a building around it's roof ..especially a 16x9 shed?
Perhaps I should really weigh whether it should just be deconstructed and
another built once the walls are up ..or factor all that into it and
postpone or even nix the project.
Another twist is the cost of the concrete for the footings/pads (already
cribbed) will be picked up by the municipality as they are repouring
curbs
on our street later this week and will have extra left over for me. Nice
guys.
So, if anything the pads can be used elsewhere as HD stepping stones ;^\

I think you need to sit back and consider two things:

- does the roof meet your requirements? Or should you abandon
it and start over?

- if it does, it will be _extremely_ unlikely for you to be able
to jury-rig _anything_ to hoist the roof cheaper than a 1-2 hour
visit by a crane.

Heck, even if building "tripods" of 2x4s or steel pipe, or any of the
other
ideas I've seen proposed here would work at all, I don't give two bits for
their safety. I'm convinced that it'd be cheaper to hire a crane than
try cobbling together tripods (the pipe isn't free either) or even
renting scaffolding.

A heck of a lot safer too.

In the scheme of things, 1500 pounds isn't that much. A delivery truck
crane (ie: those used for delivering shingles) could handle it.

The cranes they use for erecting trusses should be able to handle it too,
and they're cheap for short jobs.

According to Wayner :
Thanks, Chris. But as I indicated at the beginning, I can no longer get any
heavy equipment to the site. So I am left with doing this chore by hand.
Having a crane at the front of the house and maneuvouring it over to the
rear is far too expensive for something that was supposed to be a lowly
salvage/recycle operation.

You'd be surprised at the reach of some moderate size cranes. Like the
ones they use for lowering trees in awkward places. I've seen one reach
over a house to lower a big chunk of tree.

Can't hurt to call around and see how much it'll cost to come visit for an
hour or two.
