Metal roofing questions

Axhammer · 08-01-2010, 09:21 AM

I am building a 30 x 26 carport adjacent to my house, I hung the truss's yesterday, so I'm getting close to the roofing part of this project...

I like to looks of metal roofing, and with a 25-40 year paint warranty, I am thinking it is a good long term investment...

My plan is to install a metal roof on the carport, and later on down the road when the house composite roofing needs replacement, to replace the house roofing with the same metal roofing on the carport, so it all matches...

My house has white (or silver) composite roofing, so this is the color I plan on staying with...

I have talked to the folks at the local hardware store, it sounds pretty easy to install, just screw it down...

Can anyone tell me more about metal roofing? I like the looks, but I really don't know the in's and out's of roofing in general, and I don't want to make a mistake, I would like to think this could and would be the first and last roof for this carport, and the last roof on my house, later on down the road...

Thanks in advance!

Sounds like you are looking at an exposed-fastener panel. Won't hurt on your carport but I never recommend them for a residence or heated space of any kind.

You know the old adage "The devil is in the details" ? Well, it really really really applies to metal roofing moreso than most things. Not sure what you are asking for as far as in's and out's go but not really something one can explain thoroughly on a forum.

If you go with a metal roof don’t do the type with the exposed screws. You can get it with a nail flange similar to vinyl siding. Much cleaner looking, watertight product.

OK, no exposed screws, the nailed flange style is OK?

Any other suggestions?

There are two manners of installation for metal roofs, the concealed fastener and the exposed fastener system. The exposed fastener system uses lap screws and do not allow for the metal to expand and contract that could result in leaks in the long run. The concealed fastener system is better but is definitely the more expensive of the two. Ensure that the screws you are using comes with rubber caps or washers to guarantee a proper seal.

So when you said "Ensure that the screws you are using comes with rubber caps or washers to guarantee a proper seal" that is in regards to the exposed fastener style or both?

What style fasteners does the concealed fastener style use? nails or screws?

There should be enough details here for you to understand it better. I ddi this one 2 years ago. http://www.albertsroofing.com/Tin%20...to_gallery.htm

For a concealed fastener system, stainless steel clips hold down the metal panels 12" O.C. and are attached to the roof deck with two flat head screws, using special quick-drive screw-gun as this video states.

Ax, tin and KD show you a couple different types of hidden fastener metal roofs. Neither of which is the type we typically use over here.

The bottom line is metal roofing manufacturing is basically a regional thing so product styles and installation procedures can vary. Your best bet is to go to your local lumber yard (not box store) that’s been their forever and see what products are available to you in your area. Then whatever that manufactures installation instructions for that product is will be all the info you need.

Never heard of it.

**kwikfishron** · 08-02-2010, 10:56 PM

Never heard of your’s, never heard of his, I was going to post mine but I’m sure you all never heard of it either.

That brings us back to the regional thing.

Heard of most out there, but that's part of my job.
You are correct, though, mfrs tend to be regional. Most profiles are not proprietary though so you will find that 100 regional mfrs are selling the same basic two or three profiles under their own name. Doesn't make them any better or worse than the other. Anyone with $50k to invest can run 90% of the profiles these mfrs sell with their own portable roll-former.

Most of these middle-of-the-road profiles don't come with anything more than a paint warranty so the quality of the roof boils down to the quality of the installer as to how good the system is.

Axhammer, you will get much better information checking with local metal roofing mfr and installers than you will from your local lumber yard or big box.

Copper is the Cadillac. That stuff you guys are posting is the Kia Sorrento of metal roofing.

To the OP: I'd steer clear of exposed fastener roof over finished ceiling. There are numerous profile and gauge choices, but finish is the prime consideration. I'd only consider kynar.
