The Advantages of Corrugated Metal Roofing
What is Corrugated Metal Roofing?
Corrugated metal roofing is rippled metal sheets used for roofing applications. Corrugated metal roofing is most commonly used for commercial, agricultural, and industrial purposes, yet is now also being recognized as an excellent form of residential roofing. Corrugated sheet metal roofing has been in use since as early as the 1840’s, and has since been developed to prevent rusting and even enhance its attributes. The galvanizing of corrugated metal sheet roofing also protects against corrosion in air and water, and has allowed corrugated metal roofing to become one of the most durable and withstanding roofing materials available.
Characteristics of Corrugated Metal Roofing
As already mentioned, a corrugated metal roof is one of the strongest kinds around, so tough that it has an expected life of around 50 plus years. Corrugated metal sheet roofing is also extremely weather proof, and can withstand extreme weather conditions such as hailstorm, heat, snow, storms, and even hurricanes, as they are able to contract and relax with heat. Galvanized corrugated metal roofing is also non-combustible and fire resistant, and contrary to common doubts, is the safest roofing option for lightning strike prone areas. Furthermore, corrugated metal roofing is environmentally friendly and is completely recyclable. It is also able to reflect some of the sun’s rays, and can hence partially reduce your heating and cooling bills. Another important advantage of corrugated metal roofing is that it is lightweight, which not only puts less stress on the underlying walls and materials, but also means that it doesn’t require much framework and support. The lightweight also makes installing corrugated metal roofing a simple and therefore inexpensive process.

We want to span the 21 foot width without supports in the middle. We've placed (8) 6×6 posts in existing concrete using (4) 3/8 1.5" concrete screws in metal post holders. We can't use longer 5/8 inch bolts, we're hitting rebar in the concrete.
4 posts are 11' tall and 4 are 6' tall (12/3 pitch) on the 24' sides (8' apart). We pre-built two 28' beams with 1/2 plywood in between 2×10s. We plan on placing these on top of the 2 sets of posts with hangers.
We then pre-built four 24' beams with 1/2 plywood in between 2×12s. We plan to span the 21' opening every 8' directly on the 2×10 beams. We will then use 2×12s every 2' in between the beams. I was told by a contractor that using 2×12s to span 21' would sag without the help of the "sandwich" beams every 8'. We are going to put 2×4s across the joists & beams with a metal roof.
Any flaws in my plans? I'm worried about the weight of the roof, use of small screws in the post holders and the 21' span. Thank you!!
Thanks Bhop. I'm using the only connection method I found to anchor posts to existing concrete. I've seen lots of examples of people building complete decks, with spas on top, on these top of connectors. They are the raised metal post holders that are meant to be bolted on top of concrete and then nailed to the posts. The only difference is I can't get the single 3" 5/8 inch bolt as recommendend and instead are using four 1.5" 3/8 inch concrete screw for each post.
I'm also beefing up the railing to add support between the posts instead of the posts only being connected by the roof.
You ask what would keep the roof from blowing over. The eight post connectors are nailed 8 times to the post and screwed into the concrete 4 times. In order for the roof to blow over, all 32 concrete screws or 64 nails would need to fail. Is there any way to beef up the post to concrete connection? Thanks Again!

The restaurant industry has slip resistant shoes that work very well in greasy conditions. But they won't have steel toes or shanks.

Warranties on roofing materials are rarely used, for several reasons:
1. The bulk of the cost is in labor, rather than materials.
2. Manufacturers only cover defective materials, and the vast majority of problems with your roof are caused by incorrect installation, inappropriate materials given your location, "acts of God", etc.
3. Even if you do determine that you have defective materials, the warranty is typically pro-rated after a few years, so that after 10 years you'd only get a percentage of the amount you had originally spent.
It is much more important to get a guarantee from the roofing contractor that you hired.
Finally, although proof of purchase is helpful, it isn't usually required by manufacturers. Most roofing materials include a serial number or other method of identification, and this should be adequate should you wish to invoke the warranty. This article provides more detail: http://www.roofery.com/shingles/warranty.html.

Hcl eats metal. If there were holes in the enamel the acid when applied would attack the roofing. The damage would be immediate and obvious.
Hcl becomes diluted (weaker) when you add water. If the contractor was careful to rinse well and then you had three days of rain it's hard to imagine any acid residue could have remained or done any damage.
You might buy one piece of roofing and duplicate the cleaning and flushing process to see if it damages the metal. This could provide some insights.
good luck.

You have to have ventilation. Metal is not an insulator, it's a conductor. If it's shiny it will reflect, but it won't stay shiny. If there is insulation under the metal, then the reflective quality will be helpful, but if not, the metal will heat up and it will get hotter than hell in your attic, and make your AC work harder. The more ventilation you have, the better. Ridge vents are good.
The problem with your existing fans is that they were made to install on a shingle roof, and the flange is probably full of nail holes and roofing cement, and hard to tie in on a metal roof. They can probably be modified in various ways, (e.g. curb mounted), by a good sheetmetal mechanic to work with a metal roof, and hopefully, your roofer is a good sheetmetal mechanic. Alternatively you could put gable fans, if you have gables.

A metal roof is not installed by a plumber, it would be installed by a roofer or a sheet metal worker.
