I amazed at the problems you are having in North America with metal roofs.

As with Much in Life, 'Context is King' Given Sir Jay's 'context' (the 'Pacific North Wet', as he aptly calls it) Water intrusion - whether from just-plain Spring / Summer Deluges, or from many Freeze/Thaw Cycles over Winters - is more of a concern.

But, for Others (like myself - and perhaps You - Not sure Where 'Down Unduh' you are Been a Lifelong Dream of mine to Live in AU, btw.. ) but obviously, there are Many regions that don't see much Rain for a spell - Same Here (AZ)

EDIT: I now see, 'Bendigo' - Noice.  So, if the 'Homework' is correct, ya's get about 20 - maybe 30" of Rain - Annually? - is that Correct?  If so - I'd bet there's Some months the 'PNW' gets that inside a Month. Some areas there get over 140 inches Annually - while others, only ~20, so, again.. "Context"

Thus, for those who live where it's only an 'Occasional gully-washer' - perhaps just using the 'OEM' washers is sufficient. But - for someone in the 'Pacific North Wet', well.. Again, the 'Ounce of Prevention...' principle would seem to apply - in That Context.

Leak Risk: Because metal roofs expand and contract with temperature changes, shifting snow and loose screws can degrade or crack the rubber washers over time, opening up entry points for water."

..And thus, again - RTV's yer Uncle.

A solution - though, granted, "extra work" would be to lay-down a 'ring' - then 'finger-sculpt it tight' (ie: the way you do for caulk on a bathtub, etc) - of RTV Silicone < link to example..) around Each of those self-tapper / washer combos - Which would serve to both 'protect' those washers from the UV, and provide an Excellent, super weather / sun-proof Additional seal around all those punctures. (and, once it's fully cured, won't 'leech' anything bad into yer catchment-water)

"Overkill"? Maybe from Some perspectives, but.. To Me, that's one of those 'Ounce of Prevention...' things that may 'cost more' in cash / labor upfront - but 'pay dividends', later in durability. I have personally seen this technique work Very well on (granted) smaller applications, but.. It should 'scale'.

RTV is also the cat's pj's when it comes to sealing any 'accessory / mount-holes', etc in yer RV / trailer / Camper-van Roof, etc - Really, Any place water needs to be kept Out on passthrus / holes, etc - RTV is yer Hero.

Fwiw..

My Oldest Son took - and Passed - Bill's Course, taught by Geoff - and ref'd permies.com in some of his comms to me about the whole ball of kale..

And many arduous months / a Very Grievous Heartbreak / recuperation, later.. I joined. Loving it here, thus far - have learned SO much (and just how little I Knew..)

Proving that, indeed, you Can 'Teach an Old Dog new tricks'.

I'll ask him if I can post-up his 'Final Exam' Perm-Plans - all hand drawn, and Excellently-Well thought out.

I have adored moss for a very long time, and in the right location... seems like a decent possibility.

Indeed, and, again - I think a Lot of the 'doability' - and future Serviceability - would be driven by the Size of the roof / area to be Mossified.

Bummer, but an Important consideration - Last thing you want is to end up with a House-top made of Tinder..  (O_O)

Yah, I meant no particular 'endorsement' of that guys Vid It was just the first one that showed the 'Concept' I was envisioning / had heard of from others..  Sort of like trying to 'partially Wofati when you Can't fully Wofati'..

Cheers / Godspeed to whatever you end up with (felt / steel-over-shingles sounds like the best bet, thus far..

Jay Angler wrote:What crazy ideas can we come up with, that might help stop metal roofs from becoming snare drums in rainstorms?

Well.. if "Crazy Ideas" are fair game, here... First thing that came to my mind (besides - of course - 'industrial-roof grade felt' was, well...Intentional Moss. (and, I see that it Might not be The stupidest idea on the internet, afterall..

https://www.youtube.com/watch?v=EhmifPCnxF0 Hmmm.. So.. "Doable", but.. 'Practical'? I dunno, but.. My thoughts would be:

- I see the 'Practicality' of this idea being 'Size Related'.. Ergo: If your place is a Smallish Cabin, and the Roof isn't Too monsterous, well.. Maybe this could work (it Certainly would be Gorgeous / Cool (literally, too..  
 but if you've got a 4000 sq ft 'McMansion', well.. Maybe not so much practical.

- I also (having Installed Roofing quite a few times back in the 'Kitchens & Baths days', including Rework, etc) always think of Serviceability, down the road...

ie: What if an 'Uninvited Tree-Branch Visit' during a bad storm necessitates a roof repair - Or someday just presents with your 'garden-variety roof-leak' - Methinks trying to suss-out a leak and/or do a repair on a Mossy-Roof - might just lead to ripping it all off.. Or, perhaps your Better Half spots / falls in love with those Awesome Fiber Optic Solar Skylights and they Just Have to Have them, Now.. etc, etc, etc..

Regardless, it Certainly would present a unique 'Safety-challenge' for the Roof-climber, so.. Just thinking ahead, here.

But.. I'm Also betting it would be about the Quietest and Prettiest Roof on the block - Maybe even the whole durn State.  Just a 'crazy' thought.

a) This Site is Wonderful - including all the occasional kerfufflery over life-minutia like "foul language"  - Really, a Very subjective issue, and - in the Context of the 'Big Picture of Life' - So Not Important getting all upset over (In my Opinion..) Quite entertaining.

Same with this whole kerfuff over 'real names vs pseudonyms' - Not really sure Why it's So Hard for some people to Not grasp the "My House - My Rules" concept (that is to say, Your House, Your Ru... aww, you get it..  

As you astutely put it elsewhere - If Thoust Don't Liketh the manner in which Sir Wheaton and Staff are running The Castle - Please - feel Freeth to Go, thereforth - and D I Y.  (which is Not to be misinterpreted that I am covertly saying DIE, no - D I Y = "Do It Yourself" - which is just what I meant... Yep, Amen.
