I am considering using steel metal shingles to re-roof my home. The gauge of these types of steel metal shingles varies from 28-30 Does the stamping process increase the strength of these shingles? Would dings from hail etc. be less obvious than with a standing seam product? Has anyone used metal shingles for a project ? Pros or Cons? I have only seen one roof locally with a slate look steel shingle . The roof pitch was low like 4:12, so it was hard to get a good look. My pitch is ~ 9:12, so more of the roof would be visible.

Just out of curiosity, how big of a problem are hail dents in metal roofing (standing seam or otherwise)?  I like the idea of metal roofing, but if I have to replace it because of hail damage, then it's not nearly as low maintenance as one might think.

If you use a good quality 29 ga. or heavier, high tensile steel, with a solid decking underneath, hail dents should be a non issue. Several metal roofs that we have installed have gone thru hail storms that have destroyed nearby shingle roofs, (and cars) with no damage whatsoever.

where  is the project ?

will the  mfr. warrant the installation  where you are ?
some coastal applications are not covered

The forming of metal roofing does add strength. It also creates a situation which can hide any indentations that may occur. The various metal shingles as well as other heavily formed products will do well in hail but keep in mind that whopper storms can destroy any roof. You may want to look into whether the paint finish is warranted against hail damage and also whether the product is warranted to not leak due to hail. I have an educational site on residential metal roofing at www.asktoddmiller.com if you're interested.

Seems to be a great idea, just precide by as to what ever is in your mind.....

These shingles are galvanized or galvalumed before painting?

Texans have had a hail of time with celestial ice balls. (sorry) Here is the insurance dept's list of impact resistant roofing: http://www.tdi.state.tx.us/home/roofingx.html

Hah, darn if you aren't a kidding my friend. I'm from Texas and I know I'm going to be looking for Dallas roofing contractors; once I see those storm clouds coming, and I know my roof's going to "Hail in a Hand Basket". And yes, you can go ahead on and use that one if you'd like, free of charge.

Hail has been known to damage asphalt shingles as well, that is why we have insurance, if you sustain damage turn in a claim

And we'd like said insurance to pay our claim, which introduces some complication. In Texas, asphalt shingles are covered if enough grit is knocked off to compromise them. But pockmarks on metal roofs are deemed a cosmetic problem and not covered, at which point the homeowner is shouting at his agent "(a) pocks on your house, too." Your state's insurance rules probably vary.

.29 ga. is too thin, we never use any less than 24 ga. standing seam that will resist denting and oil canning. For resistance against "pock' marks from hail , stone caoted , shingles, shakes and barrel tile work and have a 50 year warranty

Seems to me that metal sitting directly on wood would be more resistant to dents than metal raised or suspended over rafters or furring strips.

Great thing that you are doing it with metal shingles. I would like to suggest you about SPF Roofing which is also a good technique used for roofing safety.
