Price Info on a Steel Roof

[yooperdave]

Attached is a progress picture of a new shed in the U.P.

I wanted to put the same color sheet steel over the existing adjacent garage to kind of tie them in together.

The 2 car garage is around 1,100 square feet in area.

The contractor wants to screw in new 2x4's laid flat on 24" o.c. over the existing shingles and then screw the sheet steel to the new 2x4's for around $3,400.

I initially thought this price seemed high.

What do you think?

I just had my garage done last month. It is 26X38. Two foot over hangs on the eaves and 1 foot over hangs on the gables. The initial thought was to go over the old shingles as well. But I was concerned a little bit about the added weight. It's bad enough when you have 2 feet of snow on the roof the way it is. I opted to tear everything off down to the deck. Then new builders felt. I also opted to use 1 by 4's instead of 2x4's for the nailer. I wanted to keep the height of the roof as close to original as I could so the rake trim looked about the same on the facia. I was also concerned about the wavy look you can get when spacing the nailers 2' on center, so I opted to go 16" on center. I figured this is the last time I am roofing the garage and I didn't want any reason for me to have to do it again. The next time it needs roofing, it will be someone else's problem. It is all screwed on. The entire cost to do the job was $4200. That includes everything mentioned above and a continuous ridge vent, one boot for the hanging furnace with clean up and disposal. So your price for what you have mentioned seems in the ball park to me.

Seems a little high.

I just did one myself Shed roof 22 14" panels 924 sq ft
Material cost was
$41.69 per panel
$3.78 25 ft roll butyl tape (7) goes in the lap
$14.30 250 wood screws (3) have 200 left over
$30.23 250 stitsch screws (1) self drillers in the laps
$.99 outside closure strip (22) rubber strip to seal the top surface under a soffit over hang, Flashing required to finish it off.
No other details from the metal supplier.
$1039 total material
This went up on a clean new build. It took 2 of us 5 hrs to put up the panels and screw off the field. Another hour for me to finish the wood screws and another 2 hours for 2 of us to put the stitch screws in. We drilled a hole first and then put the screw in. Cordless tools
So 15 hours of direct labor no breaks.
Use what ever labor rate is appropriate in your area.
Remember if you hire it out there is overhead and profit. That can pretty much double the direct costs.

Measure your roof. Call a Mfg or place that cuts custom lenghts of steel. I bet your looking at less than a grand in steel. So, $2,500 for installation is high. You can do this yourself, there is not a lot to it.

Nice looking barn.

Do you have much humidity there? Are you going to insulate the ceiling of the barn? Mine is done almost the same as yours, with the metal just going over the purlins. At the time, that's what I could afford, but since then, I've really wished that I had put a layer of insulation under the metal to stop the condensation. Now that's going to be one of my winter projects.

Is the $3,400 price for labor and materials? If it includes materials, then it's a good price. Labor for doing it that way should't be too much since they are doing it the cheap way and cutting a pretty big corner.

If it was my place, I would remove the shingles, check and repair the decking, install new flashing and lay down 30 pound felt paper. Then I would install the metal directly to the decking, on top of the felt paper. This is the high dollar way of installing a metal roof, but it is also the best way. While metal roofs are waterpoof and don't require felt paper under them, condensation is always a problem with them and having the metal tight on another surface is about the best way to eliminate that issue.

Most roofers will strip a roof in a day and haul away the old shingles. Ask your builder to brake down what it would cost to strip the old shingles, and then go from there. It might be cheaper to hire a crew to do this and then let him install the new roof.

If you are pleased with his work and realize that you pay for what you get, then the price is almost secondary to quality workmanship. I just got a job where I was the highest bid, but I was the only contractor who noticed things that the others missed, and asked questions about the job that none of the others asked.

Good luck,
Eddie

I see now this building is in the U.P. I would definitely strip it down to the deck and start over. With the tremendous amount of snow you get up there, my main concern would be what kind of weight the trusses are designed to with stand. That was my concern on my garage in SE MN. And you have the potential to get more snow than we do.
As far as whether or not $3400 is a good price or not, if you can, and have time to do so, get a couple more bids from local contractors. Make sure they are all bidding using the the same requirements. That way you will be able to tell if $3400 is a fair price for your area. I know that would be a fair price where I am.

I would not recommend this without knowing what the existing roof deck consists of.

Typical 1/2" sheathing is not adequate to screw the new steel to.

Weight wouldn't be a big concern of mine.

The 2x4 and steel will weight ~1#/sq ft or less.

Plus adding 2x4's and steel adds a tremendous amount of strength to the roof.

I was not suggesting that they fasten the tin directly to the deck. In my first reply to this post, I was offering another alternative that the OP may not have considered. It was something that I had just done and it worked well for me. I'm not saying it is the only way, or even the correct way. Just an alternative to consider.

I'm not aware of this, but it could either be a regional thing, or different with each metal supplier. In my area, East Texas, where we get a fair amount of rain and high winds, but don't get any snow, it is very common to screw metal into roof sheething.

It would be best to talk to the supplier of the metal and find out what they specifiy.
