@bravo________87372 I live in Texas. I wont put anything on but a metal roof. I coat all the screw heads in NP1. No issues with the grommets failing.

@minhducnguyen9276 I work on lots of modern log cabins. Most all of them opted for a metal roof. The only real drawback to metal is something that was mentioned in the thread. You might have said it. The deterioration of the rubber grommets. That is usually caused usually by one of two things. The first being improper installation. Installers put the screw in too tight and it destroys the grommet almost immediately. Usually happens with inexperienced people put on roofs with little to no supervision.] Or the sun, heat and cold will take their toll. On RARE occasions I find one that was not tightened enough. These days I start the screw and then take it back out. I shoot a spot quality sealant in the hole and then insert the screw. It takes longer but lasts much longer. On repairs I check the scresws for being loose. Usually I can pick them out. They look different not uniform. Tilted etc. Typically I take the old screw out. Using a longer screw the process I described. Every now and then the decking below is damaged and wont hold the screw. Put the screw in, then wipe around and over it with the sealant. Dont make a mess. Then I will put a new screw above and offset by a couple inches in each direction. Not inline. After all installs and repairs let them sealant cure for 24 to 48 hours. Water test it for leaks. I have been doing this for close to 30 years.

@minhducnguyen9276 Very cool. I would have to test the rubber coated screws for my area. Not a lot of stuff lasts outside in the Texas weather.. It really takes its toll. South facing sides take a beating. UV rays, wind, driving rain, hail, exteme heat and freezing temperatures. Sometimes multiple of those in the same day. So far metal and cement based products fare much better than traditional wood framed structures. One of the things I get to repair a lot is wood decks and deck rails. It does not matter what wood or which stain and coatings. 5 to 7 years and something needs fixed or replaced. They look good but take a lot of maintenance.

@minhducnguyen9276 Yep. I climbed in one of the attics of one of these retrofits once. Three of the roof rafters were completely cracked. Plywood was holding it up. I got out there fast and showed the home owner. He was on the phone with a roofing company before I left.

@minhducnguyen9276 After having dealt with all the issues of tile, asphalt shingles, roll roofing etc. I will not put on anything but metal on my buildings I have put on several. They are not hard and easy to repair.

@minhducnguyen9276 A match? Glad we dont have those.

@minhducnguyen9276 Yep I wont work on ones I cant walk over any more. Except for a few long time clients. I painted the pop outs on a 3 story A Frame about 5 years ago. Lots of scaffold.

@minhducnguyen9276 Yep We have idiots in Texas that think they need steep roofs to shed snow. LMAO. So much wasted space in the attics.

@minhducnguyen9276 There are some shingles called Slate Tile roof and they are really expensive and durable. In the late 1980s Dallas Fort Worth had a really bad serirs of hailstorms and people showed up with Concrete Shingle Systems. Good systems but they weighed so much many of the older homes that were retrofitted later developed structural problems. The houses were not built for that kind of roof weight.
