I don't know about going over the shingles with the metal, Baz.
I would have to tear off the old shingles, then proceed with the metal roof.

Over a comp roof maybe. But the wood even tho it would provide some insulation value, would seem to be at risk of rot under the metal.

Cheers Richard

Is this taking our hobby too far?


Oops, not my photo, sorry.

I don't often shop at retail garden centers but there's a Lowes in Port Orange that I check out when I'm in the neighborhood. The other day they had triple trunk Adonidia Palms in 3 gal. for $10.00 so I picked up a few along with a small topiary with a very well balanced habit and a narrow leaved variety of Cordyline that I will put in a pot somewhere and propagate. I plan to separate the Adonidias into singles and a couple doubles with more of a "V" positioning of the trunks. For $10, these are pretty nice liners!

Yeah, very sore topic. Been in litigation for four years(next month) on substantial property damage due to a ruptured water main. This is one of many points needing addressing. Attorneys doing what they do best........ Delay

I favor the system described in the photo if furring runs vertically and roof is ventilated at the eave and ridge (to prevent the rot feared) for the following reasons. Air Cavities are important and so are back up layers.

Condensation, or in other words the "dew point" will be on one side or another of the metal roofing. No problem if condensation forms on the outer surface, it just rolls down the roof.

However in a typical temperate northern climate the moisture from the air will condense on the other side of the material, and it needs a path out to prevent rot.

Building system designs be they wall or roof are continually moving towards a multi-layer system using air-cavities. The advantages are that both sides of the outer material are either cold or warm thereby preventing the typical delamiation (paint peeling - etc...) issues and buckling issues from expansion and contraction.

Below a photo from a project I did last year, just to meet the picture posting requirement.

Thanks for your input, George....I feel confident this could be done without any issues going forward. In addition, and not mentioned in my initial post, there's a possibility I may add a second and possible third story to my one story home, and if that happens...the entire roof will be removed anyway. The metal, in theory, could then be removed and re-purposed possibly. I'll have to wait and see what happens down the road. For now, this method works for me.

Nice outdoor living area, BTW. Something more property owners could use and an excellent opportunity for landscape designers and architects.

Like I said, providing a path for the moisture and condensation to escape (top and bottom) is key. However I said vertical furring, looks like they used horizontal in the blog below, but it's slotted to allow water to pass down and through. In any case, follow the manufactures guidelines, call their tech department if you have questions.

Another project of mine:


They had closed the highway north of the city, which diverted a lot of traffic downtown this summer. A real bugger trying to click a photo with all that extra traffic on Main Street.
