    initially i wasn’t going to say anything about ridge vs flat screwing. but
    when you blamed the manufacturing process for your ridge misalignment i had
    to put in my 2 cents…The reason manufacturers want you to screw in the
    flats and use stitching screws for the ridges is exactly to avoid
    stretching the sheet metal profile and causing a misalignment of metal
    closure strips, fitted ridge caps (such as yours) or other profile
    sensitive accessories… on that note, i love your vids

    Good to see you fastened at the rib instead of the field. Good point on the
    water getting through. The gentleman’s comment on the manufacturer is
    correct but in the end they’re just trying to compensate for the fact that
    many metal workers often over tighten when fastening. Good rule of thumb is
    to drive the fastener to slightly compress so that the material can still
    move. Often this is not done instead they are driven so tight that
    distortion to the material is caused and the neoprene washer is damaged.

    Would it be possible to use sheets of glass fiber to cover the roof and
    sides, and then soak all the walls in epoxy, for a perfect fit? Or would
    the contraction of the epoxy make the shed implode?

    If you use a punch, and tap it with a hammer to start your holes, the
    screws will grab a lot quicker…that, or use real self tappers.

    Nice shed! You may want to consider an opening or door on the gable end.
    This makes loading and unloading long stock easier.

    I’m kind of worried about those angle-ground front panels. if the sheets
    aren’t touched up with oxide paint you might get rust along the cuts.

    You are referring to the screens? Difference is, this stuff and the tin
    ships I already had! And the squirrels may not that much of an issue – with
    the metal siding, there’s no place for them to hang on.

    So what happened to the next video. Also, seems like you need a slightly
    heavier hammer or a framing gun. I enjoy the videos. Other than that, I
    can’t help but wonder why you didn’t assemble and then roof rather than
    roof and then assemble. Seems like it creates more work and effort on the
    tail end. I expect the assembly video might shed some light on that. Keep
    up the good work.

    The metal roof on my garage had plenty of loose screws (at least half) on
    the ridges when I bought the house. The garage was about 12 years old. Even
    aside from the loosening, the ridge shape and size is such that very little
    of the sealing washer is in contact with the roof. I don’t know which way
    is better, but if I was doing my own installation I would seal each screw
    with polyurethane caulking in either case.

    Hadn’t thought of the heat issue. Though haven’t had problems with where
    it’s been cut on 25 year old roofs.

    Ha! Just thought that too… but I can’t judge as I have welded with flip
    flops before – not for too long mind you!

    So enjoyable to watch someone who is as talented as you are at work. There
    is an ease and economy of motion that is a thing of beauty. Thank you. I
    always learn something when I watch your videos.

    The point you sort of bring up is the pitch. If you have the screws on the
    ridges, it would cause issues when you go to shovel off a roof that doesn’t
    have enough pitch for the snow/ ice build up to slide right off. The screws
    would cause the shovel/ snow rake to catch on the screws possibly causing
    the screws to rip out after constant abuse every winter. Also, a side note,
    the fact that matthias doesn’t care for his own safety after being told
    plenty of times means, he just doesn’t care.

    hi mattthias, ive always screwed metal profile sheets in the hollows
    because when you screw on the ridge you distort the profiles shape, thats
    why your ridging doesnt line up! the sheets are wider because you pressed
    the profile flat. still love the videos 🙂

    In general, product manufacturers recommendations are not designed to be
    the best way to install stuff. They are the fastest way to install it in a
    professional setting, perhaps with comparatively unskilled labour. A
    careful person willing to put in a little more time can achieve lots better
    performance often. Plus – it’s not their shed that leaks, and they can
    blame leaks on installation, or screw failures.

    After next week’s barn or shed raising video it will be a treat to read the
    comments from the Self Appointed You Tube Safety Committee and from the
    Building Code Experts. At least one guy on the crew will be on camera
    without glasses for a few seconds. That will be good for 10 or so Safety
    Committee comments. Oh then I’m sure there will be comments about improper:
    gloves, ear plugs, hard hats, face shields, shirt tails. The footings will
    be too shallow, too narrow on & on & on.
