Everyone has seen movies depicting trailers with tire covered metal roofs. A more elegant solution to excess wind noise from metal mobile home roofs is called a rumble button.
A rumble button is a 50 cent size metal washer with a neopreme rubber disk to go under it, drilled for a screw that pulls it tight against the roof. You drive the screw through the roof metal into the roof truss below. You can put in as many as it takes to silence your roof.
The buttons themselves are cheap, but if you are going to drive very many and/or do other repairs suggested by the Mobile Home Doctor, you will want to check out a reversable, cordless drill and kneepads.
The trusses in mobile home roofs are not very wide and you will have to feel around to find them. I would suggest successfully attaching a button at the roofline and the drip edge of the roof and snapping a chaulk line between those two points. That will reduce the chances you miss the truss when you drive the screws.
If you do miss, don't try to convince yourself it will be OK and the metal will hold the button tight enough to prevent a leak around the screw. It won't. This makes a great place for a small square of Peel & Seal to solve the problem.
Finally, I would suggest looking at my legal and safety issues page before you or someone you hire start this project.
