Well the ribbed galvanized roofing put on barns lasts a good 50 to 60 years.
The church I used to attend had the white painted metal. It was put on in the
early 80's and still looks white, some fading but no rust. It was put on with
ring shank nails and plastic washer. Washers still seem ok but the nails are
pulling loose in places. What is the latest. Is the screw supposed to be put
through the rib or on the flat part. I was told the latest research shows the
flat part stays better because there is no flexing as happens when fastened
through the rib? Anyone know?

Hi Folks
We need a new roof. We would like a metal roof. I am trying to learn as much
about metal roofs as I can. I will list what I have learned, tru or untrue.
1. The rubber washers used with the screws that hold down the roof can break
down in time, causing problems. The solution is to use a seamless roof, which
costs more.
2. An old shingle roof left under the metal roof will break down in time and
cause the metal roof to become loose.
3. The warranty period is based on how much the paint will fade on the roof.
So far, I have only found roofs with 30 and 40 year warranties. I have been
looking for 50 year warranties. A friend of mine got a silver metal roof a few
years ago, and the color was all the way thru the metal. This seems to be the
best kind of roof to get, but my wife does not want the silver color.
I also would like gutter helmets with the roof, and so far I have no luch
with this.
