roofing valleys


@ tinner - I just caught you were referring to the buckling in the old copper with the picture. That has nothing to do with the nailing and certainly didn't cause any leaks. That was the fault of the way they were installed. Roofers were sent out with a copper on a coil (which is softer) and valleys formed in the field using foot tongs or even stomping them in. The copper you use is harder and breaks nice and flat. (I am thinking you already know this.)

roofing valleys


The warped valley is SS. I've also seen copper, aluminum, and steel valleys warped.
In each case, I was called to fix leaks. In each case, the open valleys had splits and tears from the constant flexing.
In closed valleys, the constant flexing had split the metal and torn the shingles.

Max width of usable valleys should be 14" which will allow nailing within 6-!/2" of center without hitting the metal. When using small slates, the max valley size is 12". That's 12" metal in the copper pix.

Hi Guys,

I suggest that you pick up a copy of "Copper and Common Sense" Published by Revere Copper Co. and read it cover to cover, twice. It was developed and produced in reaction to the significant number of problems that roofers and sheet metal mechanics were having with sheet metal. It is a very well written and illustrated little book, that will help you enormously, and keep you out of trouble.

Hi Ron,

One of the points I was trying to make with metal, and this is very well documented, is that thicker is not always better. We know that metal moves. Aluminum expands about double what steel does, That is why I spec Kynar coated galvanized steel with return hems, for copings.

If you insist on nailing through your valleys, I would stick with .024" aluminum, not .032". I guess we all have our reasons for doing what we do, but nailing through valley metal causes many of the leaks I find in MD. Maybe where you are you don't get hydraulic pressure too often.

At any rate, Have a Merry Christmas, and stay safe up there.
