It is important to drive or install the screws correctly. This is a really simple procedure, but quite often it is done incorrectly. If you mess this up your roof will leak, so taking the time to correctly fasten the screws is exceptionally important. This video will be an excellent guide that will clearly demonstrate the correct way to tighten a screw.

The screws that you will be using will have a rubber washer with a metal cap. The rubber washer is just a bit smaller than the metal cap. You want to tighten the washer so that it spreads to the edge of the metal cap and not past the metal cap. When you tighten the screw it’s critical that you don’t drive it too far.

It’s a natural reaction to exert too much pressure and tighten the screw as much as possible. This will over compress the washer by expanding it too much and breaking the washer. If this happens back out the screw to relieve some of the pressure. If you over-tighten the screws then they might leak and will also need maintenance sooner.

Conversely, it is common to under-tighten the screw. The easiest way to determine if the screw is too loose is to see if you can spin the washer. If the washer spins, then the screw is too loose and should be retightened. You will develop a feel for fastening the metal panels correctly, but just pay close attention to ensure that the screws are installed correctly.

Screws Should Be Installed Straight And Not Sideways

Screws that are installed sideways or tilted will not permit the rubber washer to seal correctly. This will create a possible leak point. If you notice this has happened then back the screw out and redo so that the screw is straight.

Do you have a corrugated metal roofing job? If so check out this video that discusses screw placement + screw location + overlapping on a corrugated metal roof

[gregsettle]

Very helpful video. Love the very specific instructions on each step. Thank you!

[huejanus]

Did my metal roof with a cordless drill. Predrilled all the holes when the panels were on the ground, then set the clutch to the proper setting and let her rip.

[LukeAyers]

This channel is so useful! Thank you very much

[guzman]

All these tips helped me a lot thanks!

[thejoyfulgardener]

Thanks for the tips, most useful. I will be pre drilling the sheets to make sure alignment is correct and no fuss tightening.

[albertramos]

Wow! what a good video, thank you so much, I am getting ready to do my roof.. and what a cute voice... Thanks again!

[doneown]

Awesome video, she cuts right into the main problems with these, installation fowl-ups.

[ShakespeareCafe]

When making an instructional video leave out the music or keep the volume low.

[rollformingbrotherunion]

very nice tips about roofing installation

[cynthiaayers]

Stack all the sheet metal for the roof, measure and Mark where each hole is going to go, then drill all panels at once.
Three generations of roofing and building.

Pre-drilling doesn't save time, it adds time. Second, whether you pre-drill or not you can still get a nice straight screw line with a string line. I don't recommend pre-drilling sheets prior to installation. Often the sheets will need to shift slightly upon installation and you can easily find that your holes are no longer where you want them.

[shaineriches]

You dont need to use a screwgun atall, you can use a drill with a clutch and set the torque on the drill just remember not to set the torque to high or will overtighten the fixing.

Screw gun is unnecessary for anyone with a few hours experience using a modern impact driver. Trigger is pressure sensitive and power setting exists for low power applications such as metal roof screws.

[highlanderthegreat]

does also covering the screw with some kind of silicone count and help???

[stuckster]

Good info. But you def don't need a dedicated screw gun. Most newer drill drivers have variable speed and adjustable clutches.

[frednurk]

Grabbing drilled metal bits with bare hands was the number one injury at my works.

[Steve-tnis]

18 year old corrugated metal roof. Screws with rubber washers are wearing out. Should I replace with new and larger screws or use some kind of product that will coat each screw?

[julianarodriguez]

Can I use these screws in the Philippines

[mikescalise]

the screws used in this video are prehistoric! New screws are all one piece, bottom out the cupped shaped head against the sheet metal and the internal rubber washer is seated just right. Washer is shielded from the elements.
