Branden, check out the Copper Development Association's website (www.copper.org) They have a 'Contact Us' link you could try. Pose your question to them and ask for supporting literature to show the builder. In my experience they have been helpful. While we have wide-ranging temps here in the northeast, they tend to occur over a broad span of time. I have lived in Alabama and Georgia (and visited Florida) and understand the temeperal variegates you describe. As highly-regulated as you are down there, what does Miami-Dade say about flat-lock? | ||

We see from 20 below F to over 100 F temperature ranges here in north western PA and flat lock works fine. It was 30 below here one year. I doubt they get those kind of temperature fluctuations in Florida. | ||

i've got a builder who doesn't want to let me use flat lock copper on flat roofs on a slate roof i am doing because of a bunch of info he has gotten on thermal shock. the brief description as it relates to my situation is this, down here in the summer copper can reach temps well over a hundred degrees and suddenly a rain cloud can dump six inches of rain in three minutes and drop the temp of the copper down below seventy degrees and the sun comes right back out and heats it back up to well over a hundred. this is a typical summer day and all of this can happen within twenty minutes and several times a week. his claim is that the sudden change in temperature can crack the solder joints his solution is a built up roof (not my thing). any help here? |
