Got all my roofing supplies on order. Missing anything?
 
Hi Guys,
First off, thanks to all that helpmed me with the decision process, especially AaronB.

Update on my roof tear-off / replace project. This is a flat roof, my personal house. Let me know if you guys see anything that I might be missing.

1. Firestone APP170 13 rolls
2. Firestone Base sheet, 12 square
3. 2" IsoBoard 36pc
4. 240' Cant strips
5. 10 Gal Karnak Primer
6. 10 Gal #169 Aluminum Paint
7. 160' Copper reglet counter flashing :thumbsup:
8. 10 Gal Bulldog Flashing
9. 1000pc 2 7/8" screws and olympic plates.

Also picked up 7" scraper, $30 skill saw, assortment of blades, hooked knife blades.

Still have to get skylights, 2x6 for curbs, deck screws, propane, fire-extinguishers, hose, etc.

Supplier is going to make a rooftop delivery, which is just sweet.

Gonna have 3 of my guys rippinging the old roof off.

If that includes 10% waste, and adding for flashings, you could darn near get to FM 120 with that many screws.

You mean FM 1-120? LOL.

500 screws was $70, and 1000 was $89. Plus the supply company is cool, and said I can return anything I don't use, even by the screw, by each cant strip, etc...

One question, I am still not 100% convinced that ISOBoard is a good idea on wood decking flat roof. Can you confirm one way or another if this is a good idea or not?

Thanks.

All these views and no one can anser this?

Ok, what is the configuration of the roofing assembly? Cold roof assembly or warm roof?

There should be no inherent issues with installing ISO board over a wood deck. What, exactly, are your concerns with it?

Thanks Aaron.
Warm Roof Assembly.

I was reading the directions on the ISO board, and it only mentions metal roof deck. Doesn't mention that it is only meant for that, but stated that ISO insulation boards should be used on metal roof decking. It has vague terminology, that is why I am asking about it.

I plan on placing the base sheet over the ISO board and screwing it down to the decking. Is this fine? Should I be putting some type of sheet, (water/vapor barrier) under the ISO board? Thanks.

We have done it your way many times. Be sure to screw and plate every corner of the ISO board before you install the base sheet. If you don't over time, the ISO board will cup and model through the base and mod.

YOU MUST BE VERY AWARE OF THE FIRE RISK. I still think you should take a torching safety certification at minimum, and know how to cut the base sheet and fire block all corners, penetrations, etc. This is very risky and I still recommend you NOT do this yourself because of risk of fire. Remember to keep a water supply on the roof, preferably a live water hose, and set a fire watch for two to three hours after you shut the torches down, and then another. Roofs can smolder for many hours before you will see any smoke.

I know you're going to do this anyways, but I really recommend against it.

Thanks for confirming.

There is a torching safety certification? I am glad someone has concern about this. Every supply I have been at, all tell me its not problem go for it. I've torched Mod before, so not as scared. Slightly concerned because this won't be over old roofing. I will deffinatelly sit there and watch for smoke/fire for a while. Have the garden hose ready also. Cost me a ton for 100' hose. Got fire extinguishers too.

I'll be honest, I asked around for the peel and stick stuff, but I swear, no one carries it. Not even HD or Lowes, but they have the torch mod. Plus the supply where I ordered all my stuff from said they don't even want to buy the peel and stick because they are conserned with people using it improperly. BS flag on this one, but whatever.

Then everone did tell me that torch is pretty much the best in our area for flat roofs. So I gave up on the peel and stick.

I am honestly more concerned about rain. If it starts to rain on me, I will have a heart-attack. I pretty much have 5 days to get this done, I know I can manage in 3, but next week is all rain so far, and I really can't/don't want to reschedule this project.
