Green roofing material-Armorlite roofing?

Just posted over in the remodeling forum with this question.

Am looking for a green roofing material to replace asphalt shingles. Have looked at metal varieties, but don't have the question answered yet if we can keep the copper gutters using metal. Forgot the term, but something about metal fatigue (?) using two metals together. Saw on HGTV pro site a line about Armorlite roofing. It's a GE developed polymer product, has a limited lifetime warranty with pro installers, a 50 year one when self-installed. Seems to be fairly new, and used mostly in California. Has anyone used this? or know someone who's used it? We're in New England states, apparently it hasn't gotten nationwide yet, so can't get opinions around here. It seems very light weight, which would be good, especially for shipping these days. I know, is a polymer green? but that's what I trying to find out. Hoping this forum is active as the kitchen one, I practically lived there on-line when building ours- year and a half ago, and that one has great people. TIA for any info.

Dissimilar metals dont get along well and will corrode through osmosis. Some metals together are okay, others not.

Here's a link that might help:

Osmosis? Not quite, you may be thinking of electrolysis which is not the correct term either but many people think it is. Galvanic corrosion is the correct term.

Reminds me of a story... NC State was playing basketball in I believe the ACC tournament which was being televised nationally. Charles Shackleford was interviewed after the game and stated something like "I can play with my right hand, I can play with my left hand, I'm amphibious".

Actually, I must continue to disagree as well:-) I don't think you are aware of the facts behind this technology nor how rapidly it is progressing and becoming commonplace. Seattle is by no means on the forefront of green roof activity - we are well behind Portland and Vancouver BC in this regard - but the real hotbed of activity is in the midwest. Chicago has more green roofs than any other US city - over 200 and covering more than 2.5 million square feet. Dearborn, MI has the largest, 10.4 acres covering the Ford Motor Company truck plant. Minneapolis, Philadelphia, Baltimore, Washington DC, Raleigh NC, Atlanta, New York City and Toronto are all very active green roof areas as well. And then of course there are the dozens of green roofs scattered across California, both commercial and residential. This is not an isolated movement nor is it a flash in the pan technology. Modern green roofs have at least a 30 year history in this country. There is a very active and increasingly growing community of architects and contractors specializing in this approach and scores of companies dedicated to the technology and materials to build and plant living roofs - a simple search through Google will turn up literally hundreds of them. One of the incentives that stir this on is the same you claim to be a deterrent - the downturn in the economy has made it even more appropriate to pursue this technology. Initial costs may be higher to design and install a living roof compared to a conventional roofing system, but this is easily offset by the extended lifespan, the lower maintenance and the energy savings realized over the life of the structure - an investment in a living roof actually saves money.

DIY Sedum Green Roof
Q
Comments (21)
Okay, so we have our green roof all in except for a couple of planters on our overhangs,,collected all the sedums we could last year and had to finish with others this year,, what we have in place is a commercial building system roof, which uses epdm to finish off, since we did not like the suggested toss gravel on the roof and let it ride, I did the green roof, have to admit ours varies from the site above, when we planted ours I wanted patterns so what we did was first make sure everything was well sealed and ready, the littles puncture will leak so if you do the nails or staples you must place a patch over them,, next we laid another layer of blue foam on ours for added protection because we do have a problem with the deer jumping onto it,,after that I custom missed a very light weight soil, drew out patterns on the roof,, from there I used a combination of barks to do intricate designs,and outlines to emphasize the sedums,, I layed in 4 inches of soil , the original 3 did not seem to be enough,, then planted with various sedums based on their foliage colors basically creating a large mosaic,these are beginning to fill in this growing season,, so hopefully in the next couple of years it fully fills in ,, right now it is still nice to look at however because it is complimented by the barks,, gb

Grass as a Green Roof?
Q
Comments (3)
Where exactly do you live? In my opinion unless you live in a big City with bad air or live in a place were its hot and your garage is overheating I'd say that grass isn't the permaculture answer to your problem, you need to maintain it and pull weeds or spray it with harmful chemicals, or just let it be a safe launching point for invasive plants, and its on a roof so thats one more obsticle to pulling weeds, Could you possibly install an irigation system and grow some moss up there? You will need to get an EDPM membrane to cover your roof and protect it from the moisture, and soil, other than that and the wieght on your roof its just like planting in shallow soil on the ground.

Green Roof/ fiberglass gardening materials

Mel! what's up? There doesn't seem to be a whole lot of action in this forum... I can't say whether your garage/building is built strong enough for building and putting raised beds on!? But from my knowledge of having a one car flat roof garage many moons ago. I never gardened on it, but he is my 2 cents... I myself wouldn't put raised beds on it, seems to me like alot of weight in one place all the time. If I was to utilize the roof I would go with a few containers ie 5 gallon buckets ( tomato's or peppers etc ) A) they can be moved around B) and or taken off if needed without disturbing your plants! The down side imh would be; A) Wind! would want to make sure your containers don't get blown over or OFF the roof and B) might want to put some kind of white ground clothe down to reflect the heat! That tar or asphalt shingle like to absorb heat and you might find yourself watering 3 or more times a day if you aren't using swc's. Well that's my opinion.. goodluck to you ya if you procede with your 'green roof'.

Well, thank you sierraeast and mike13, Loved your remarks and helping me out with the correct term. And yes, went to roofing101. Living on the edge of woodsy,land trust land in Connecticut, going with a true "green" vegetation roof would be interesting. Wow, Would need a heavy duty water barrier though. And not sure the construction here (mid-fifties) would hold it up. Haven't seen the weight per square for it in charts like other materials. Ours is looking pretty green now anyway with all the licken on it. Truly like the metal roofs, but even with some barrier for fasteners (copper to steel/aluminum/galalume,if there are any) between gutters and roof,there's the run off from roof into gutters. Read somewhere galalume shouldn't be used near ponds and streams, which we have, a brook and pond,naturally occuring. Ok, still hoping someone with a composite roof will speak up here, how about Tamko Lamarite Slate composite roofs? TIA

Went out roof shopping today. One place handled only Certainteed products, Grand Manor squares at $90. My builder said that's down from when he was using it on Ct. shoreline a couple years ago when it was $200 sq. Then went to a place that handles Tamko products, asked about their laminate/composite product Lamarite. Guys kept laughing, saying they couldn't remember the price it was so stupid. I wanted to laugh too, so asked them to look it up. It's $500 a square here. For that probably could go with real slate, even copper! Who knows? One good thing, you can install yourself without voiding warranty. That's good for people like me who've been remodeling a couple of homes for years now. But for the real bottom line, will probably go with the Certainteed...Grand Manor (or one that weighs slightly less.) Gotta check the live and dead weight specs for my roof rafter situation. Thanks all.

Our grand manors were 185.00/sq. in oct. '06. Glad to see some things have come down! We got semi lucky w/ our copper flashing costs as copper went up again,( after going up), tripling over costs previous years soon after ours was installed. I believe the grand manors are in the area of 425-450 #'s /sq. If you need that info, go to their website:
