screws backing out

I've seen a couple of posts about this. A roofer who came out to reflash the chimney said we had screws backing out and we should put new/bigger ones in. Do we need to worry about this if it is not leaking? The roof was installed 12 years ago over plywood decking with felt underlayment.

I would certainly tighten any loose screws but replacing them with larger ones is not a bad idea either. This can be a point of maintenance with exposed fastener roofs vs. concealed fasteners.

Big +1 Todd. Exposed fasteners do have that potential to them. They certainly can be a great option but they are a bit sensitive to installation.		Eric Novotny An informed customer is the Best Customer! 8/14/2013	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/18674/find/
Thanks! should we worry about it if the roof is not leaking? we are selling the house and don't want to spend another bunch of money after having to re-flash the chimney. But we don't want to sell a lemon either.		Sarah Lee 8/14/2013	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/18675/find/
My guess is, if you have to go through a home inspection, this will be caught and be required at that time if you do not do it earlier.		Todd Miller Isaiah Industries, Inc. 8/14/2013	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/18676/find/
