    I've roofed since 1974, I do Inspections and repairs these days. I cannot stand roofing videos on YouTube, But my response is to applaud you for your presentation, Very well done and you are in my thoughts, a Professional!! Hands Down, well done Brother. I enjoyed this ☮️☀️👈🏽
  • Got a corrugated galvanized roof put on 1980. Back then we used neoprene washered roofing nails nailed into the elevated ribs not on the flats. Neoprene is still holding up and no leaks. I’ve painted the roof once with aluminum paint to stop a small amount of rust that started appearing around the 25 year mark. Not bad for 40 years in upstate New York weather. I am sure I would be on my third roof with shingles

    You've just increased my knowledge about this important subject. Thank You. No exposed fasteners. Striations to combat expansion/contraction. Useful.

    Just found your channel. I’ve have learned more in this 7 minute video than in the past year watching others. You are direct and to the point and for that I am thankful !

    When I install these metal roofs with gasketed screws, I use a screw gun with a clutch set correctly, as not to overdrive the screw, blowing out the gasket. Lastly, I use an appropriate colored Geoseal tripolymer sealant bead over EVERY, screwhead, EVERY screwhead. In 35 years, I've never had a callback for a leak. Only call back, was for when a huge oak fell on their home, to redo their section damaged with new metal. Good day, sir.

    Very professional video. Easy to understand, especially by contractors, who do quality work.
  • @davidbrown8303
    When I watch YouTube videos about abandoned houses most with metal roofs are in good shape while the ones that have shingles are falling down from water damage.

    We have had this type of roofing, we call it V-crimp, corrugated is different in Australia over 60-70 years, we screw in the hill not valleys stops leaks.

    GOOD SHOW, installed a "GALVALUME" corrugated panel roof in 2009 and placed screws only in the high spots, tops of the panel's peaks to prevent / limit leaks. No leaks yet . THANKS Standing seam seems like the better choice because there are NO EXPOSED SCREWS. I also used acrylic roof cement caulking at entry points of the screws for added seal... The proof is in the missing ceiling stains, NO LEAKS is what it's all about.

    This fella here is right I have a friend that has a metal roof on his house, and he had a leak shortly after installation from a contractor that he knew. I met my friend years later with him asking me to find his leak. It had taken me three tries to find the leak. Here they never put a sealer down each length of a valley, and a lot of other work that this contractor had done wasn't done correctly. We have been slowly making things right for him.
  • We also use drip edge up the rake and fold over like you did on the eve. We use the Malco edge roller. If you don't want oil canning on the flat panels run half inch foam backer cord underneath the center of the panel vertically.

    Good video , I'm a retired roofer and have laid thousands of sq. feet of metal roofing. Nice presentation
  • @razony
    I'm planning on a metal roof and Luke described this in a way that even I can understand. Straight Talk. This video made me a bit more wiser and knowledgeable to make Better decisions! Thanks Luke!
  • @terryhill4732
    Great tips and I love the old style snap-on panels those will be around when we're long gone, most of all I love that all the fasteners are hidden

    I helped a friend at work build a 30x60 foot log house between 2000-2002. The roof peak was 21 feet above the slab, with a 40 degree pitch. We installed 19 foot-long red corrugated panels...took several days. I often wondered about the rubber washers and their lifetime before failing. The standing seam is a far superior design, taking the washer failure possibility out of the question. Great video.
  • @kermitefrog64
    That was an excellent video. I have used the first type of metal roofing on my storage shed. I will use the 2nd type of metal roofing when it is time to do my roof on my house.
  • Great video, do you recommend drilling 5/32 pilot hole to allow for expansion and contraction?
  • @Chris_at_Home
    I did a roof with a similar 3’ wide product called Norclad here in Alaska.i did the roof and lived there for 30 years with no problems. My new house has standing seam roof.
