Rape the home owner??
If the asphalt shingles are so good why are they being covered up with tin??
Money burning a hole?
The asphalt was good 20 years ago. But it had started to curl and shingles blow off.
I put three inch screws through firring strips, the shingles, sheeting, and into the rafters. The firring strips are not coming off. And the steel will still be there long after I am dead.
