Good video fellas
Awesome tips. I've been doing tpo roofs for years, and instead of a pre weld, we just do a quick small tack weld every 2 feet or so at least 3 inches in to ensure the tpo doesn't move when welding it, and they NEVER leak, it'll save you some time for sure.
I been doing roofing for 23 years and well this is the first time, that im taking to learn the right way, I haven't done tpo too much and watching this video makes me think how wrong I been doing it and some of my coworkers that think they are the number one roofer ... I'm gonna keep on watching this because I want to be good at it.... thanks great video

Been with Centimark for about 4 months ive learned a lot. Just kinda felt the need to see what you guys have to offer. So far so good! thanks for this video i look forward to watching what you guys have on here and UP my game. I do have a question about the robot.. When we start running the seam the robot seems to be welding slower than the speed of the robot moving and it wants to wrinkle the 10 foot wide sheet.. Any ideas

Hi i work in nv crew i work this People every layer install is strech to much whit big Steel strap is in residencial roof is a good idea ? Or maybe faulure about the guaranty were can find that rules strech or not ?
Hi, there. Please reach out to our team at (877-423-7663) for questions about TPO. Our experts will be happy to answer any questions you have!
And I have been taught to keep the roller about an inch from the tip of the lister. Is this true?
What happens if your hand weld is greater than 1.5"? Isn't more better?
That is my question too. I thought he mispoke at first but then he repeated it later in the video.
Hi. The hand weld must be a min of 1" and a max of 1.5". If you'd like more information, please send us a message on Facebook or Twitter and will share the EverGuard Mechanically Attached Manual with you.
@@gafroofing Thanks for the reply but we asked a "why" question and your sending us to a place where were not going to get a "why" answer. It's just going to say the same thing you just said.
No, its not better. The standard hand welder nozzle is 1.5" or 40mm wide. The thing is, when welding the lap, youll have the welders nozzle at a 45 degree angle, not perpendicular to the lap, so you lose a tiny bit of that 1.5". On top of that, you gotta leave an 8th to a 1/4 inch of the nozzle out of the lap to make sure it welds. These people have it dialed in. You dont have to reinvent the wheel.
If the weld is stronger than the sheet itself, why can you pull it apart? Good luck trying to tear a sheet of TPO in half with your bare hands.
You can pull it apart because you have leverage from the two strips. if you cut the seam and compared ripping a strip along the seam vs ripping a strip of TPO the seam would be substantially stronger. If you epoxy glued two ropes to a random piece of TPO you could do this experiment too.

Why do these guys continue to tell people hand welds are maximum 1.5”. This is not Industry standard which says hand welds are to be minimum 2”. And btw, never tack weld membrane as it causes damage if windy during install. Bad habits die hard.
