    Anybody have metal roof experience?

    Trying to decide the difference between furring strips. 1x2, 1x3, 1x4, pressure treated, not treated, felt between shingles and furring strips, foam insulation or this new radiant double air insulation?

    Any advice/experience good or bad would be appreciated.

    Oh yeah, budget definitely important.

    Are you planning on covering up the shingles with a metal roof? They put a lot of metal roofs on down here in the Keys and they always strip the shingles off before putting on the metal.

    Yes, Florida building code allows you to cover 2 layers of singles and that leaves an extra layer of protection. Plus I'm doing this by myself so pulling old roof would take me forever.

    My first thought would be furring strips would create a place for strong winds to get under it. Keep us posted on what you do as at some point I will have to do the same.

    I have seen 1x4's used almost exclusively as purlins, (what you refer to as furring strips.) And never pressure treated! (Some sort of chemical interaction.)

    If roofing over bare decking a layer of felt is definitely called for. Probably not as necessary over shingles, but your call.

    I don't see the need for insulation myself.

    My present metal roof was installed over an existing metal roof! No problems.

    The biggest controversy seems to be the screw pattern. Some only screw on the crimps and never on the flat while others fasten on both. Not sure what the answer is- it may just be fodder for barroom discussions...

    (edit)- You definitely need to instal with purlins. Air circulation is absolutely necessary and if well secured will not pose a wind problem. Sometimes, depending on the direction of wind-driven rain and the shallow pitch, a barrier strip between the roofing and the ridge cap will prevent water from being driven up the roof slope.

    Be sure to install a weather barrier around the perimeter of the entire roof. I ran 2 plys of the 24" with the top ply 6" set back from the first layer. This will keep out any water that blows under the metal.

    Check the installation guidelines suggested by the manufacturer of the metal roofing. When placing metal roofing on top of existing shingles, some manufacturers require wood strips on top of the shingles and some manufacturers require 1/4" of insulation over the shingles and the metal applied on top of the insulation.

    Many homes in my rural area now have metal roofs. One company uses wood stripping as required by the manufacturer and the other company does not in accordance with their metal manufacturer.

    Many of these roofs were done several years ago and they still look practically new. I have not heard any complaints from those who have had a metal roof installed. Mine is 8 years old and I have had no issues. They are, however, very slippery to walk on compared to shingles (use caution)

    I had an experience in using metal roof on my house. I do not know how it is complicated as I paid an agency and their exprts installe deverything and I've just paid. The only thing I know they also installed snow guards for roofs. They suggested me to do this as there is alwasys a lot of snow during winter.
