Thanks just the info I was looking for.
Where is the short lip and where is the fat lip? This video sucks!
the metal roofing sheets also can use the prepainted pattern ppgi, it will more beauty. such as the millitory pattern, wood pattern, etc…
Very Informational, Dude You Are Awzum!
I strongly recommend not using roofing material like this! This product has exposed fasteners, and the rubber under them WILL fail over time in the sun. Once that rubber degrades the seal is broken and you have little leaks all over the place. Only use metal roofing with hidden fasteners!
Different panels require different methods to screw off American standard requires you to screw in the flat . I have screwed on the rib before on a pole barn in on the inside when you look through if you screw it on the high rib you can see daylight to me that is a leak you do what the manufacturer says to do which is screw on the flat I know it doesn't seem like the right thing to do but it is in in the north country I live in Maine if you install a metal roof you must take the gutters off because when the snow slides off it will tear the gutters write off every time
#6 having Anything penetrate the roof in the first place. All exhaust pipes and chimneys can be done out the wall.
#7 Having Skylights in the roof. They will leak no matter what you do to seal them.
#8 Forgetting to put a dab/line of sealant under where you plan on putting the screw if you decide to put them in the valleys as a extra measure/precaulksion.
Video is clear, nicely done, and explains very well. I wonder how long does the rubber washers on the screws last before they start leaking and need replacing.
what is the point of installing the strapping to the roof ???
I install screws in the flats per manufacturer specifications and exceed our local code requirements by following the Miami-Dade screw pattern
Fibreglass is best

Lots of arguments about putting screws in flats or ribs. I've installed a lot of metal roofs. NEVER had a leak! If you put a hole in a piece of metal you create a place for it to leak…. I always put screw in ribs 12 to 16 inches on seams and a row across the roof 4 to five feet apart. On perimeter we do put screws in the flats on 8" spacing to hold edges down which keeps wind from getting under the metal. Never had a leaker and never had a roof blow off. Two points I absolutely agree with in this video… pipe flashing technique and lapping edges… long edge on bottom.
Well the guy may not be perfect but experience makes the master and even thought i went to design school i realize that the real knowledge is in the experience. Experiencing the weird and forbidden things will give us a better insight
Screw in the flats. In the north country , when you have to shovel the roof, the snowshovel will rip the screws out.
We are raising money to help the UNDERPRIVILEGED. We are almost completely funded, but are at a dead end as of now. So we decided to act to raise money publicly. We target single mothers/fathers that are putting in an effort in society to move forward and provide a healthly community for their child/children. Giving back is what life is about and hopefully when they are in a better position, they will also do the same. Thank you for everything. We appreciate anything received in advance!

Is regular felt a thing of the past ? Why does everyone use this new synthetic underlayment ? Great videos by the way .
Tio es el mejor. algundia sere como vos. de ese calibre
are you a Lic Ca contractor?
Hi Eric, we've been very busy this week – 13 home inspections. On the re-shingle, I understand your logic and if it were my roof I would want the shingles stripped off to find any underlying issues and have them repaired. But, everyone has a budget. ;-)
hi eric. what do you rec for roofing shoes for a 8 pitch asphalt shingles? what do your guys use? looking at buying a pair of cougar paws. what do you think?
rip it all off and wait for me to get there and show you.
the ICBO says that, you can install up to 2 layer of light weight shingles, or 2 layers of shingles over wood shingles, you can install up to 600 per square if you install light weight concrete tile, more than 600 lbs per 100 sq ft of roof you will need a structural engineering report
lol right on brotha. we can start tomorrow.
6lbs per sq. haha maybe you should go back to school.
this will put extra weight on your home. this is what not to do. lazy mans roofing. it will wreck your trusses and structure of your home. how long have you been roofing?? hahah
Eric, I have always wondered why install a second layer over existing shingle? Is it a matter of cost of removal only? Or are there other reasons.
good job as always,you have to open roofing school and teach ex-prisoners how to install))gov have to spare some funds for that.
