Flat Roof Installation (Fully Adhered vs Mechanically Attached)

Learn the difference in the two common types of flat roofing membrane attachment methods, Fully adhered or Mechanically Attached.

You seem to show a simple example but I have done them all and you explain it well. We rarely did a fully adheard roof unless it was under 100 square. On 100-50, 000 square it was always mechanical attachment. Flat roofing is an art not a science. The details are where it will fail and you must follow a set of guidelines. It's hard to get an entire crew to prefect the manufacturers guidelines. I spent enough time up on those roofs to know that you really have to want it to succeed. The whole crew has to buy in to get perfect results. Otherwise the foreman is going to run around putting out fires all day everyday. I cashed in them chips when 1) I was to damn old and 2)I could make more money to do half the work. I respect you low slope guys because I've been there. Keep up the good quality work and get yourself a rinobond machine or three.

Hello! Thanks for the informative video! I need to replace my flat roof. Is mechanically tpo better than SBS adhere roofing system?

[EBPization]

Hey great vid! Question: can fleece backed TPO be welded at the seams?

[p]

so you could glue or fasten the same tpo?. can you also do both if you have a plywood wall and just fasten the flat roof?

[olahlouis]

How about wrinkles how do you eliminate the wrinkles with mechaically fastened system ?

You always need a cover board if you want any kinda warranty’s

I really like this guy. I can tell, 1 second all it takes, by the way he speaks, explains and carry’s himself he is outstanding. Better be the owner? If not he needs his own company. He also needs to teach me all he knows so I can DOMINATE like an Exterior Pro Roofing BOSS in my area/region. I shall take over all the NW region of this beautiful country with this mans help. 😁👍🇺🇸

Thank you for your explanation. One thing I still can't find is info on edges. How do you do them? I put rubber on a low slope roof years ago, adhered to aluminum drip edge. After a few years it blew up. I have a roll of pvc but don't want to move forward til I'm sure I can do it right.

What happens with ice build up and pull away?

Can I do mechanically attachment to a plywood roof?

[mister-action]

I'm a contractor and have done plenty of roofing, and roll roofing. I have a 2.5 pitch roof between two 5/12 roofs.
On the 2.5 pitch I have a rubber roof i put it on in 2012. It looks like I'm going to need to replace it soon. I'm thinking about doing a PVC roof. Menards has a 10 x 20 sheet. With 20 year warranty. It looks like that's the best solution that they carry. My question is can I glue it down over my rubber roof or would I need to put down insulation sheets again and glue it to that. Thanks for any replys!
I don't want to do it again in 10 years. So I think I want to go with PVC. I'm 62 so this is my last roof. Thanks again!!

Can I use TPO directly over wood? I’ve done it over a wood wall, but I need to do it over a wood monolith- it is a decorative part of a Dunkin’ Donuts...using insulation will raise the deck too high

I have a question, , hopefully you can answer. On a fully adhered pvc roof.
How can I weld the seam without creating a ripple effect on the other side of the weld. Seems to me, , being fully adhered, the only part that is not glued is the 6” pvc you leave for the robot to weld the seam, hot air gets trapped in on other side of the silicone wheel and now there is puckering or ripple effect. Any clues or ideas on how to get rid of that.
Thanks a lot

Can I mechanically install a pvc membrane that is 10 ft wide?

[macknumber]

So on a mechanically attached PVC membrane roof. Do you screw into the trusses or the old metal roof? Also, how far apart do you need to fasten it?

[siahleon]

Don't do this line of work. I want to swan dive off the roof everyday. I hate my life. DON'T DO IT!
