Flat roof, #30 felt or roofing cement?
Hi all, I’m working with a friend of mine who is a handyman couple years bebore me. I just have him help me to build a patio about half inch per foot for my regular client,the house is about under ten miles from the beach, but he keeps opposing me about things.
First, I told him the rafter start from ledger board, he said why don’t we start from the 2×6 fascia, I told him fascia is built just enough to support itself.
Second, I told him that I want plywood have to be screwed to beam and rafter, he said nobody screw roof sheathing, I had to lied to him that’s what H.O wants. He said screwing is time consuming, I finally told him we’re going to apply liquid nail and screw every 12″. I thing I’m going to put some more screws on it.
Third, I told him my other friends told me that roof under 2″ per foot, using Henry of Black Jack under roof roll is the way to go. But he keeps told me that way would be time consuming and labor intensive.
Would you pro please tell me what should I put under roof roll, #30 felt or roofing cement? I would use your suggestion to talk to him instead of argue to him.
Any input would be great appreciated.

You are not planning on using 30lb felt as a roof surface are you?
You need some more study time on built up roofing.
60 or 90 lb roll roof and BUCKETS of cement, not tubes.
I won't evenget into it any further, Piffen is the expert here.

Use Certainnteed self-stick Lo-slope roll roofing, Prime the deck, roll the roof and tell him to shut up. If it's too labor intensive to do it right ask him how labor intensive is it to fix it every three months? If he still won't shut up, hire a roofer to come out and give a consult. Throw him fifty bucks for a half an hours time, or even some suds, and your bud won't be able to argue.
Remind him that this is your client. If they're not happy, you look like an ####, loose work all while your bud is ten miles away on his non-laborintensive butt.
Hi Tungle, is your buddies name Tangle?
I would not do either of those on this roof. Roll roofing was OK in it's time, but that time is past history. It is a product that will last five years at best on this roof you are building.
There are several peel/nstick roof products that have a surface finish like the old roll roofing, but are ten times as good a product and easier to install. They work a lot like ice and water shield, but have re-inforcing membrane inside and the mineral surface on top for wear and weathering.
Up here, the brand available is Polyglas. You have already heard about another one. There are instructions on the label. have your helper read them to you so you know that he has read them. Then go to it.
To lay it, I roll it out in place to get it positioned and straight, weigh down half the rool, then backroll to it, and peel the backing off while rolling back out again, then backroll the other half, and repeat.
flashings? you two know how to do flashings to tie this roof into the shingle roof?

Another thing you might look at is Resource Conservation Technology's paint-on fabric reinforced system:

I don't know that anything can truly be idiot proof, but this one looks like it should be fairly idiot resistant. ;-)

Folks, thanks for all inputs. Peel and stick stuff sound good to me but they require torch down which I never work on before, so I told the H.O to order EPDM. This is kind of simple to me, from what the sales rep. told the H.O on the phone this requires three steps:
First, apply the base coat with a roller about 36" wide.
Second, put a sheet of fabric on when the base coat still wet.
Last, apply the top coat with roller again, when the other coat still wet.
The product will be arrived by next five business days, I'll tell you how good it is after I work on it.
The material cost about $460 plus about $100 for shipping to cover the 19'x 16' patio. It also come in sheet which cost double the price.
Again I appreciate all of you for the great suggestions.

That sounds a lot like the Resource Conservation Technology system. Is it from them?

Sounds like a liquid product then. I think there are some liquid EPDM s out there, but haven't heard of them using a fabric.
The polyester re-infoprced syustems are pretty good though. I would be interested in hearing about the product you use and confirmation of its name.BTW, th epeel'n'stick products do not use a torch to apply. Torchdown is called modified bitumen and there is no peel off backing.
