Probably the best as it can be formed into difficult shapes easily]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=840&Focus=9061#Comment_9061 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=840&Focus=9061#Comment_9061 Wed, 07 Nov 2007 23:03:32 +0000 Paul in Montreal Posted By: tonyold car tyre inner tube?

Rubber is destroyed by UV radiation.

Copper is also recyclable, as is aluminium (and lead of course). All three are long-lasting, but copper and lead are easier to work with and solder whereas aluminium is very difficult to solder without specialist equipment. Speaking from experience, galvanized steel only lasts around 95 years.

Gosh, you outed me as a Time Lord

As for the 95 years quote, there are quite a few buildings of that vintage around where I live an pretty much all of them have had their galvanized flashing in a state with so much rust that they require replacement. We opted for copper because of the heritage designation of the house and the fact that it should last a long time. The old slates had lasted around 108 years but were pretty much at the end of their life (the seasonal changes here can be tough due to the extremes of temperature from the -30s to the +35s). Lead flashing is pretty much unknown here from what I've seen, the majority being galvanized steel or copper, sometimes aluminium (the latter usually on more modern buildings).

As for thefts, copper is just started making the news (there was a story this morning). In the US, air conditioner condensers are now a popular target.

Most roofing materials should last longer than 30 yrs too.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=840&Focus=9305#Comment_9305 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=840&Focus=9305#Comment_9305 Tue, 13 Nov 2007 06:43:34 +0000 Mike George https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=840&Focus=9529#Comment_9529 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=840&Focus=9529#Comment_9529 Fri, 16 Nov 2007 19:45:28 +0000 david I get it by recycling old copper hot water cylinders. I cut the top and bottom off with a jigsaw and get quite a big piece for next to nothing.
I make a bonfire and heat it to red heat to anneal it and make it easy to work .]]>
