new standing seam metal roof ?s

[nybirdman]

Boy,I havn't seen a standing seam roof installed since the 60's.Lost art.
The one on my parents 1860 farm house is still good.Snow/water will come off in a hurry.

I have a similar roof design and the metal is 26 gauge, which is considered plenty strong for my snow country region. 29 gauge is still sometimes used in economy situations. Standing, sealed seams are very worthwhile to have if you expect a lot of snow to collect, stay, slide. If heavy snow accumulation is rare then the overall tightness and hiding of fasteners matters less. We have a fairly long run in our shed roof and put in a french drain with a storm pipe and drain rock along the drip line to convey most of that water away from the foundation.

Its good to hear that others here have and like this type of roof construction. It seems to me that these types of roofs would add equidy to property more than other types any how.
I'm some what commited to standing seam/metal as the 30' x '30'lower part is 2/12 pitch and the upper 30'x30' is 4/12 pitch ...so there is not many options with a 2/12 lower that is going to see alot of water by design . I intend to capture the run off into an underground tank/ tanks for irrigation use mostly.There is'nt much price difference$ 0.35 /sq ft between 26 g and the thicker 24 guage ... maybe +/-$150 or so, plus many more colors to choose from in the 24g.
BeezFun: don't laugh, but I did down size it a bit because it looked funny RR

What does the contractor say about moisture condensing between the metal and felt? When the ambiant temp. is cool and the sun heats the metal there will be condensation when the humidity relevant.

Condensation does not happen when something cool is warmed up by the sun? It happens when warm, moist air is cooled down.

$2 per square foot sounds like a fantastic deal to me. I got a quote when for a standing seam roof when I built my house about 8 years ago, and it was well over that - around $5 per foot IIRC.

Decided not to go with the metal at that time - went shingles, will go standing seam as an upgrade down the road.

We have a shed roof design on our house. Instead of 30# felt, there was a plastic type of underlayment used. It stood up to wear and tear during construction quite well.

The roof over the garage has a segment that is around 60' long. You can see where they brought in a machine to form rolled stock and make the roof sections. This roof was called a "Modified Standing Seam". Fasteners were screwed into the underlayment and the formed roof snaps in. It's basically quicker (and hence cheaper) than standing seam. I'm sorry and I don't know more about these procedures and can't explain it better.

The design of the house was a shed roof because I hate roof problems. No dormers, hips, valleys, seams --> No Leaks! (well, hopefully less...). An added bonus was much lower cost. Someone I know was building a house at the same time as we were. They had 1/3 the roof area but the same cost. It added about $1K per dormer for all the custom metal work. They also had some valleys in there.

We put 6" gutters on this, and then 4" pipe (including burying the gutter drains at the ground). I also put snow guard rails on so the rare snow we get would not come crashing to the ground all at once, saving those on the ground and the gutters from undue wear and tear.

As for cost, we just got a job quote and not a per square foot. But this seems analogous to the OPs roof challenge. I do know that the cost of this roof was less than doing shingles twice. We also had insulated/sealed attic space, so the metal roof really helps there too.

Thanks for the pics.

I looked up my records, Our quote was $5.65/sq ft 6 years ago for 24ga color crimped standing seam. I thought that was plenty then, and still do :laughing:

The contractor was a local area family business with a good reputation, if I have a problem, they are around and responsive.

I 'm about to put a new 30x60' standing seam roof on my tractor building. One of the the Quotes I've rec'd is for 24 guage concealed fastener painted 16" pans @ 2$ a sq ft.. The method they use to fabricate/extrude I've no experience with .. What I understand they do is bring a linear extruder/bender to the job site and make the exact pans required from coil stock..so they build the job on site.
Have any of you TBNERS any experience with this method ?

With that roof it is the only way I would do it. $200 a square installed for painted is a bargain. Most standing seam uses just under 24" pans,with the 16" pans you are getting more fastening power and hence a more secure roof. Ask them what the spacing is for the fasteners. Important for high winds. I have seen many metal roofs peeled in a high wind storm. What is the substrate material. Most roofers I have talked to like 1" poplar as it really holds a nail. That however is not common in todays market unless you saw your own.

My roofs were done that way. It is a slick on-site operation. Pick up truck with the coil of 24 ga. roofing on it, feeds into a trailer behind it with the forming bender, cut off to the exact length needed. Another truck had a generator and compressor that powered everything. They had an air motor driven seam crimper that runs up the seams. My roofs are not old, installed in 2005 and 2006, but so far, so good.

24ga is heavy enough roofing at least where it installed over continuous sheathing. Supply stores sell 29 and 26 gauge in the pre-cut steel I think.

$2/sqft sounds like a steal deal to me.

I agree

my first thought after seeing your LOOOOONG roof is how much water is really running off that roof at the end?! you literally could fill a pond with that much runoff.

Have you asked for customers of contractor work theye did that has simalar long roof like yours? Do you get sudden downpours of rain?

With a metal roof you need to prepare for a snow pile, it happens inevitably. With that much run in your roof you are going to have a monster pile. Be advised. If you do put gutters (maybe culverts in your case) make sure you hang them low so the snow doesn't take them down when it comes off.
