We are trying to help a 92 year old gentleman fix his 10’x52’ mobile home roof.There is a lot of rust damage. He has patched it in different ways over the years. White Knight, adhesive and tar paper, even plywood and base sheets in one area.
We are wondering if there is something we can put over all of this without building trusses as the older trailer may not take the weight, and the cost of this may be prohibitive.
We have been looking at rolled roofing products, ideally with a cold application or metal like this - https://www.mobilehomerepair.com/mobile-home-metal-roof-replacement-install-diy/
Hoping there is someone who might offer us a bit of their wisdom.
