Our group is going to start installing metal roofing on top of asphalt (not wood) shingles on 200+ sheds. The existing roofs are 20 years old. We have already purchased the metal roofing.
Should the existing roofs be treated for mold and other problems before the new metal roof is installed?
We plan to remove the fascia and reinstall it.
Do you have any other cautions?
Will you please send me the general instructions also?

Installation instructions should be available from your manufacturer or if you let me know what profile of metal roofing you are installing I will try to help you.
No special treatment necessary but you should use underlayment over the old shingles.

I'm in the same situation, but I've been given conflicting advice on underlayment.
One contractor says no to its use because it creates 2 vapor barriers and that is bad.
The other contractor uses it.
Who is correct?
www.advancedmetalroofing.com says no vapor barrier when installed over shingles.
Who do I trust?
