New Carport

[AlanB]

As someone else said, the cost of me installing it was only like $75 less, worth the money for me.

I went with extra bracing on mine, I also added a foot of height and went with the heavier wall tubing, mine was a cardinal, ended up being $1000 I think.

Of course a month or so after buying it, we lost the land we were renting and I had the pleasure of moving it. (see AlB's house rework on Projects thread) it was not that bad, but I sure wish I had not had too do it.

I would highly reccomend them.

Mine is fully enclosed with rollup door; window; and walk in door. Base size is 20x26(?) with an 8'x10' door opening to get my JD990 inside. In addition to the rebar I also added the big screw in mobile home anchors along each side. This Fall I reinforced the roofline where it meets the side wall because of high winds hitting the building sideways caused the roof to constantly chatter.

Champy,

Thats a nice looking setup you have!

What did that set you back?

PSDStu - Here is an excerpt from my prior thread......

http://www.tractorbynet.com/forums/projects/101201-new-home-my-990-a.html


Started with a basic setup from All-Steel Carports, then enclosed all the sides and cut in and mounted the doors and windows using low-rent mobile home type hardware. The normal wall height is 5' so I had to upgrade to get the 8' clearance for the 8'x10' rollup door (which goes up nicely and tucks out of the way leaving a lot of room inside) with a rough price of ~$3800. I had some quotes for a pole-barn that started at $10k-12k for the same size building so decided to go this way. Added mobile home anchors that are bolted on the inside steel frame and drilled into the ground about 3' deep. By the way, putting up one of those rollup doors is a real back-breaker since you lift the whole assembly (rolled up) to the header to mount it on brackets.........sweated that one.

One added benefit of this approach is that the county building inspectors don't require you to get a building permit, and this type of construction is considered a "temporary" building (no fixed foundation/footers) = no property taxes applied. Also it will allow me to actually move the building if we ever wanted to at a later date.........which also eliminated a lot of hassles with the Mrs. regarding deciding exactly where to put the building.

Dmace,

I'm in Brookfield and would appreciate the name & number for the local reseller.

Hey Bob,

My local reseller is A1 Auto and RV sales in Rochester, NH. They have one setup outside their shop on Route 125. PM me if you want to stop by and check it out in person. I am right off of Route 16.

As for snow load, let's see if this link will take you directly to the right photo. They can handle the load. quote]

Although there's no light weight guys on that roof it only represents about 8 pounds per square foot.
Snow loads for manufactured housing designed for Wakefield N.H. are 35 pounds per square foot. I'd get a design spec in writing. That said, I've seen these even further north in N.H. & they seem to hold up well. As for enclosing the sides, I'd also get a wind loading spec before covering. MikeD74T

I had one of these installed about five years ago. Had the heavier frame which added a foot of height, set on RR ties. With one extra sheet of metal on each side, total was about $1000 installed. I have since added metal to enclose both sides, about 1/3 of the east end & 1/2 of the west end. I keep two narrow front tractors & part of my garden tractors & attachments in it. Have been very satisfied with it! ~~ grnspot110

. . . Snip . . .
Between the weight of the carport and the anchors on each side, it's going to take a pretty tough wind to move one.

For Info, Bird and anyone else in snow/wind areas: The photo Bird linked to show 15 guys on the roof of an 18x21 unit. At 250 # each that's only 3750# total, roughly equal to a 10 psf snow load. Most areas require a higher psf capability. At my 8300' altitude in Colorado, I need 65 psf. That would be 24570# on that same 18x21 carport, or 98 guys at 250# each.

The moral of the tale is: Check it out - If you live in a snow zone get a guaranty from the manufacturer as to what load it is designed for. Same thing for wind. I built my home for 75 psf snow load and 110 mph winds.

Hey Dick, I live just north of Dallas. I think our carport had a inch of snow on it once. So what do I know about snow load? I certainly don't disagree with your numbers, but it seems to me that your calculations took the total weight of those people and spread it evenly over the entire carport, when in reality each person's weight was concentrated on one square foot or so; i.e., that person's two feet. And then of course, other parts of the carport had no weight on them at all. How would that alter your calculations, if at all?

 

[Dmace]

By calculating the total load on the roof (including roofing material) and averaging that over the entire roof area, you are really only figuring the total average load on the framing of the structure which is how Dead Load is calculated. If you want to calculate dynamic live load for the roofing material, then you would take the load (person) divided by the area (1sq.ft. for feet) and that is the load on that concentrated area which is basically how snow load (Live Load) is calculated.

I saw the installer walking on that metal roofing in between supports and it didn't budge, so I know it is strong. Plus loading the roof panels which are one piece (4ft by 21ft), just one guy picked it up in the middle and the flex was unnoticeable.

I will put some pics up today or tomorrow since it has 9" of pretty heavy snow on it now. Boy is it nice not cleaning off the truck or all the snow that would be in the bed.

RE: one inch of snow - Point taken, Bird! Sometimes, snow load isn't a concern - I'll bet you've had more weight in ice loading than in snow loading

RE: Concentrated vs average loading: The concentrated loading of one man on his 2 feet would be be of more concern in figuring penetration - seldom a problem on a roof, but consider if you were standing in the attic on the drywall ceiling (?straddeling a joist ?) instead of standing on the joist.

Averaging the load over then entire roof considers the structure holding everything up. The usual failure mode in snow loading is that one structural member fails when unable to support it's share of the load, which places higher loading on another . . . Dominoes!

DMACE - RE Live vs Dead load - I understood just enough of that in school to be dangerous - I'm a chemical engineer and mostly handle that stuff with the old "a 4x4 seems OK?, Use a 6x6!" approach

I looked into T-N-T and it seems like a great product. I'm going to do it...period. The rep I spoke to told me that Vermont area gets an extra post (6 vs 5) for the 18wide by 21 deep gable (B) model. I'm going with the heavier gauge steel.

QUESTION to you guys who have them. Did you guys consider the vertical roofing option? Also, does the (B) type come in the same size range as the others? I am going to order the vertical metal roofing which is a $300 option...that keeps the ribs from holding back the snow from sliding down the roof.

Unfortunately, my zoning administrator takes any type of building very seriously and requires a full-blown 5 page permit, inspection, the works. ANY assembly of materials is considered a structure...and must be permitted. Even a pre-fabbed plastic shed requires a permit, fees, inspection with measuring tape, and a "pretty please with sugar on top" attitude to get approval. A neighbor of mine built a garage for $3,000....maybe it's 20x30, simple stick built with T-1 siding and metal roof. He told me it was appraised by lister for $30K for property tax purposes. Ouch... I think this type of carport will help me avoid such a hit and give me the shelter I need.

I bought mine from gaport.com They don't list Vermont but you can look at another state to figure options. I got the vertical roof and boxed eave style. I does not cost much more to go taller. I even went 5' longer. JC

 

[BTI]

We have sold a few of these.
If you are worried about snow load, you can ask them if you can buy extra bows for them.
They will pretty much build them any way you want.
They can even put the steel on the roof with the ribs of the steel up and down instead of long ways.
This helps the snow come off much better.

I've been thinking of one of these as a firewood shelter. Getting tired of trying to burn damp wood and the makeshift arrangements for keeping it covered haven't worked that well...in addition to being eyesores. Anyone using theirs for firewood? Stone floor sounds about right with old skids to keep the wood up a little.

I thought of devoting half to two-thirds of it to firewood and then leave one side open so as to back in implements from the side.

[Bird]

Did you guys consider the vertical roofing option?

I can understand that being a worthwhile option some places, but I didn't consider it because I knew we'd never see enough snow to worry about it. In fact, I didn't worry about heavier gauge metal even because I only wanted shade in the summer to keep the interior of the vehicles from being so hot, and protection from rain when getting to and from the vehicles. Of course having a roof over the vehicles also almost entirely stops any dew from forming on the vehicles at night.

 

[Dmace]

QUESTION to you guys who have them. Did you guys consider the vertical roofing option?

If I had seen that option, I probably would have gone with it to help with snow removal. Since the ribs of the roofing run along the roof line, I leveled the ground so that it had about a 5% slope towards the rear of the carport. When it rains, the water flows right down the roof and off the backside.

Today it got another 8" or so of snow on top of the 6" that was already on it. Boy is it nice not to have to clean off the truck before plowing, and the load of sand in the back doesn't get all wet and frozen either.

Pics to following once the sun comes up again.

I had this eye-sore, small pole barn made when I had my garage built. It works well for my firewood but now I need a larger one to house my tractor and tent trailer as well as the firewood. So, I am going to dismantle it and rebuild it twice as large and farther away from my house.

 

[Engine66]

Is crushed rock ok for a foundation when there's frost in the ground? I figure the whole enchalada will lift a few inches, but a shed I have that's 12x16 has had no problems in the frost and it sits on crushed stone. I'd like to avoid having to pour a monolithic slab and was thinking a well-compacted bed of 3/4" crushed stone mixed with smalls and fines would form rock hard like my driveway. Any thoughts?

 

[Dmace]

The whole driveway where my carport sits is 1/2" crushed gravel which is also known as "road base". I don't see having just crushed stone as a base being a problem, just as long as the structure has a good base/foundation and is not just a few posts sitting on the ground.
