Moved to Fl to retire and purchased a double wide mobile. It has what looks like a diy metal roof install over shingles. It was installed in 07 using 1x4's. and note the overhangs. This is the first metal roof on something I owned. I was inspecting the screws that are popped to do maintenace. I was able to reset some and others just spun. I would like to go over the roof before hurricane season. Should I use a longer 1-1/4-1-1/2 screw in for repair or caulk the hole and put a 1 inch screw beside it. Regarding the end overhangs, were they finished like this for a purpose ? I would like to cut them off at the drip edge and put the normal metal gable trim. Any thoughts on the screw replacemnt idea or the overhang change. Thanks GBY

Yes, the ends were done that way for a reason, it is called laziness. You can cut them back and install standard metal roof edge trim.
Thanks for comments. I'd consider a re-do but getting helpers during quaratine and having a low immune system is going to be an issue. That would be the ideal though.I guess longer screws would do the trick but I'm leary of piercing deeper in the roof decking and leak. I guess since it was ignored and allowed it to get into this shape it would be better to not let it get this far.

Based on my metal roof installation the guys used # 10 diameter screws . They explained to me that IF at some point in the future they started to leak then the right thing to do would be to replace with # 12 screws . That way going into the existing holes fills the space due to the larger diameter . In my opinion 1 " long screws seems quite short I would go at least 1 1/2 " or 2 " . Also if you are going to pull existing screws and replace with larger/longer I would also add a shot of caulk to each hole before installing the new screws . Doesn't cost much and your up there any way why not .
That was my first thought !!

Wonder how well those 1x4's are attached to the roof below..........
IMO a 1" screw is long enough provided it's screwed thru the flat part of the roof panel. You want a longer screw if it goes thru the raised portion. My house and barn have the old 5 crimp metal roof panels. While most of it was originally nailed, I've replaced a lot of the nails with 1.5" screws and added 1" screws where needed on the flats - have had no issues with the screws and living on top of a hill I get a LOT of wind.
The biggest thing I don't like about your roof is how it's open on the sides. That is where wind could get under the roof.

That is what I want to fix before the winds start blowing. There are no screws on the raised sections.
I missed the part where you said the roof was installed over shingles. That and the 1x4s would indicate the need for the longer screw. Roof screws usually don't pop loose unless the wood they are screwed into is puny. The 'rubber' washer is prone to deteriorate and fall away.
I was suprised to see the screws popped , but those that did came out rusty with the pine deteriorated. The new screws placed beside them went in solid. My thought was to get a blister pack of #12 and #14 and see what works best before I get a bulk box.
