What Is The Best Flat Roofing?


I have been a residential roofer for 12 years. So I have done many asphalt shingle and metal roofs. Friend of the family owns a motel with a 30,000 sq ft flat roof. What is the best product out there now for this project? And what is the best way to price a job this size?

Re: What Is The Best Flat Roofing?


where at? several factors involved. you could always go over an existing mod bit or b/u with a 1" iso and a single ply tpo or pvc. not a fan of epdm but different regions have had better luck with it.

Since your not experienced with doing flat roofs,I'd suggest getting local bids from qualified installers ,follow up on their references and hire the one you feel is capable of getting it done right.
Its an expensive system,and warranties will be void unless installed by certified roofing company.

Keep in mind, single ply is COMPLETELY different than shingles. Requires different equipment. You may want to follow the advice above or find yourself in a big mess or at the very least get someone qualified to assist you. Do your homework before!

Re: What Is The Best Flat Roofing?


I really do appreciate the advice olfrt n Brand. I've been doing homework since I was approached with the opportunity. I've researched the web, talked to friends and associates, and talking to you guys. But again, if nobody ever let me cut, I wouldn't know how to cut. If no one ever let me measure, I wouldn't know how. If I were never given a chance, I wouldn't have my own successful business. I do appreciate all the advice and opinions.

This is NOT the flat to cut your teeth on. You have been warned, best of luck to you. Put your ego aside and listen to what everyone is telling you.

Every contractor should be familliar with 3 phrases, I can't, I shouldn't, and I won't. This one falls under you shouldn't.

As much as I wish I was, I'm not fortunate enough tobe able to pick n choose my work. My three phases are: I'm hungry, need to eat, and gonna feed my family.

I'd find a qualified person willing to do a joint venture. I understand your situation, I really do. Got myself into some trouble on a siding gig being in your shoes. I'm pretty decent on a flat and I would not take that on alone, equipment alone would be a hassle and if you have no clue, you will struggle to make cost.

Re: What Is The Best Flat Roofing?


I'm not trying to come off sounding like a jerk. But what I am asking is what do professionals think the best product is and an equation on pricing this job. Thanks for all the warnings. I will be the first to post if I totally screw this up,but don't leave your computer waiting to see that.

Re: What Is The Best Flat Roofing?


Part of this equation will be which product can you get certified by the manufacturer to install?

You evidently have the CAN DO attitude...

Just don't let your ego over ride the common sense you hopefully have...

If you can get certified through IB roof systems, they have great support along with factory install technicians. It would also be about the best product on the market but it is BIG$$$$.

TPO is a great product as well , also a plastic membrane. These are probably your most user friendly applications.

The place is getting solar panels. They are required to get a New roof. They are getting prices under $100,000. Everything I've researched is telling me this job is minimum $120,000 for torch down; $200,000 for TPO and EPDM.

Re: What Is The Best Flat Roofing?


When something like this comes up, I find it's best to call the different manufacturers and talk to them about installation techniques. They know more about what they're selling than anybody here will know. Then do as much research as you can on the product since you haven't installed it before.

But I am with you as far as having the confidence to do it yourself. It amazes me how often pro's on here say "Hire someone else to do it". Once you've done enough carpentry, it's not that hard to learn something new, I do it all the time. Difference of opinion I guess, I don't understand it.

If that's what you've researched then keep it at that, don't even think about lowering it to be competitive. I remember on a roofing job I was helping with, the guy I was working for got multiple bids for putting on some 3-tab. He got one price at $30/square, one at $40/square, and one at $58/square. He figured the guy priced at $58 a square was way out of the ball park and that he didn't want to do it.

So he hired the $30 a square guy, he lasted about two days then left, said he couldn't do it for that low. Then he hired the $40 a square guy, they lasted a couple weeks before we fired them. They had their rows going up and down like a roller coaster, never heard of a chalk line I guess. Then we found out he was unlicensed, had no insurance. So we resorted to the $58 a square guy who worked out fine.

The guys priced under $100,000 might be skipping something, like workers comp. You don't want to stoop that low and do the same thing to be competitive. Let the builder know that you are properly insured, provide WC, and provide a warranty consistent with the manufacturers warranty. If he still wants to do it cheap, then let him do it cheap. He can hire the lower priced guy, but he may be calling you back anyway to finish.

Re: What Is The Best Flat Roofing?


Your attitude is commendable for sure. But cutting your teeth on a flat that is 30,000 square feet with (i'm guessing) multiple penetrations that need to be properly flashed and (I'm guessing) some substrate repair needed before roofing.... is borderline insane. And I don't mean ANY offense by that at all. It's a huge project that a typical commercial roofer would probably use a fairly large crew on. They would bring in a dozen guys and have that roof torn off, all repairs done and the new roof back on in a couple of days.

If you've got access to that many experienced roofers who know what they are doing on a flat that size, then do your research, pick a product (I agree on the TPO rec), get certified with the manufacturer, figure our your costs and desired profit and price out the job and go from there. If this is something you think you and a couple of buddies can handle, don't. That's my best advice.

Cut your teeth on residential flats or even small commercial flats before you take on a 300 square project.

That was my point exactly. I really wish this guy the best. But as you say, this is borderline nuts. It might seem like the answer to the OP's problems, but in reality, will probably come back to bite the OP and leave him in a worse predicament.
