Hi All,

Short question. Long answer?

Many people are using metal roofing in my area. But, they often use barn
or garage metal roofing which is attached using exposed metal screws,
directly thru the roofing to the underlying plywood or trusses. Home
metal roofing is attached in a different manner, very expensive to
install.

Anyway, I'm told that with the garage metal roofing, the roofing expands
and contracts as it heats and cools. The screws loosen in the wood
and/or elongate the holes thru the metal roofing as the roof works back
and forth. Leaks develop, etc. Home metal roofing is installed in a
different way.

I've heard of no complaints about their metal roofing. Can anybody tell
me if the above problem is actually a problem? One may be able to
tolerate minor leaks in a garage or barn but not a house. The source of
the above information is a very good carpenter/builder, knows his stuff,
and keeps current with building codes.

Email me directly if you want.

TIA,
