Does anyone know anyone in the New York/Long Island area that uses this cool roof system and knows the proper application?
I could be wrong, but since I have never heard of Hydro-stop, it must be relatively new, therefore nobody is going to have a hydro-stop roof that is over 20 years old. Once again, you are talking about a coating, not a roof system, A roof "System" by definition includes everything from the structural roof deck uo ie Thermal Insulation, coverboard, and roof membrane, which can be one of many many types, Single Ply, Built up, Modified Bitumen. You have subsets of all, mechanically fastened, fully adhered, ballasted.So if you are not a fan of HydroStop, what do you recommend if one wants a +50 year life from initial install + maintenance?
Do you have direct experience with HydroStop / Premium Coat when it's installed over a properly cleaned-repaired-prepared flat concrete deck, tapered isoboard, then only HydroStop per manufacturers specs?
Anyone have a HydroStop - Premium Coat roof that is over 20 years old? 30? Maximum?
Thanks in advance;

Jagans reply includes: "Let me try this again. A roof waterproofing membrane is a matrix which consists of one or more reinforing layers and at least two layers of waterproofing material. If a roof system fails, and you paint a waterproofing material onto the failed roof, the failure usually telegraphs through the overlay (Paint)".
Ok, yes, fully AGREE! Roof System includes multiple components.
Why does Jagan NOT agree that QCP - GAF is a FULL ROOFING SYSTEM? Per the company and above QCP has:
*Primer to go down on almost any base - new construction concrete or old roof systems.
* Water proof comprised of a base coat of liquid applied HydroStop Foundation Coat PLUS a polyester membrane PLUS a top layer of HydroStop Foundation Coat. Just had a fairly long and detailed conversation with the GAF Area Technical Rep.
* Multiple COATS of the PremiumCoat - or paint pe Jagans. This, as explained by the GAF Area Technical Rep is a Sacrifical or Barrier that protects the Foundation Coat + Membrane that provides the true water proofing. Hence over the years, the top coat that is exposed to the environment wears away and roughly every 7 to 10 years is cleaned and reapplied!
Yes, like repainting a house, one does NOT get a new house each time it's painted! Agree. BUT as long as the level of protection is fully updated - whats the difference? Not seeking a new building each 10 years, simply seeking to KEEP an effective building envelope!
Seems to me that GAF - QCP has a full roofing system, with multiple components. Guess am not clearly explaining as Jagans is focused ONLY on the coating of Premium Coat. So exactly how does one get a title of 'Roof Master' on here? Does this mean one has simply made x number of posts - or is some level of skill and expertise required?

Is this NOT a Roofing SYSTEM? Maybe am very, very slow and dense, but sure looks like a multi component system to me... But again, am simply a 'newbie' on here!

Sorry about the misspelling, I am usually pretty particular about that. Well I consider the day I do not learn something a sad day, so I am always open to learn new "Tricks". Unfortunately, most of the new tricks in roofing really are tricks LOLOL. There are some very good sources on here including 1985GT, and Eric fro WOW, so I would listen to what they have to say, as well as myself. I have EPDM roofs that I designed approaching 25 years but in the design I included a 12 inch cover strip over the field fabricated seams, because at the time I was in contact with Walter Rossiter who worked for NIST and his findings alerted me to the fact that EPDM fails due to T-Peel at the field fabricated seams. I have had good luck with multiply Built up roofs with an SBS cap sheet, EPDM, and with Thermoplastic membranes I have some fully adhered Sarnafil (PVC) roofs that are still performing that were installed in 1984. Fibertite (EIP) is also an excellent single ply and I have many of those that are quite old. It might interest you to know that the preferred roof in the middle east is white Sarnafil. I think that is what is on the KABA, if I got that spelling right. That's the box with the meteorite (Black Stone) that Muslims circle during their Haaj.From Jagans Profile:
About jagans "BiographyProficient in Carpentry, Plumbing, Electrical, HVAC, Profesional Registered Roof consultant for 25yr"Humm... Professional is misspelled and maybe it's time that an old dog learns new tricks?
Can anyone advise of another Roofing System that advertised "Roof for the life of the building" with the backing - reputation similar to GAF? Am very interested if anyone can, as we are about to spend +$1/4 million US on a new one and want it to be the best on the market for our building and climate!
Thanks in advance;

Jagans - reposting from my post above:
"Not trying to promote this company - product, just trying to find others with experience, either good or bad, to help decide if we should install this roofing system. Again, we plan to tear off the old TPO and ISO, inspect - repair the deck, then install tapered ISO for insulation and provide some slope, followed by roof system as recommended by manufacturer - general contractor hired to professionally install."
Fully agree and not focused on the Warranty offered - trying to focus on real solutions as we have to replace our currently roofing system. We hired a licensed Roof Inspector to do a Nuclear Survey on 5'x5' grids, and +85% of the results on this moisture survey were above spec. Therefore have been informed per local code - we HAVE to tear off and start over!
The condo has flat concrete structural deck with Post-Tension Cable system. It is 13 stories tall, and roughly 76' wide x 236' long; roughly 18,000 square feet.
Current plan, subject to revision:
We have hired a licensed professional engineer to do a building inspection of structure + electrical + roof + all mechanical systems + paving-foundation + sea wall + anything that we need to address for the next 12 years. We are required to pass a Structural and Electrical Recertification in April 2017. Therefore putting together a plan of what to do - when to do it and estimated costs between now and the 40 year recert due in 2017, and up to the 50 year recert required in 2027! This will ensure we don't have any deferred maintenance - overlooked projects that impact the building.
Back to the repairs as we have to replace the ROOF and do exterior repair/repainting of the entire building. Current Rough Plan:
Finalize 12 Year Reserve Study - Projects and Timeline
Tear OFF the entire current roofing system, down to building structural deck
Clean - inspect - repair as needed with plan not to see it for +100 years!
Install anchors for work over the side of the building, as needed
Install base waterproofing system OR LightWeight concrete / ISO board for TAPER of at least 1/8" per 12" up to 1/2" per 12" (optimal?) followed by waterproofing.
Paint with non-skid material
Complete other building repairs which will require work on/from the roof
Once ALL other repairs are finished and roof traffic back to minimal, THEN clean roof and install final coats of sealant per contractor and manufacturer recommends for a +20 year warranty.
Once all this is done, hire the Registered Professional Engineer AND someone from manufacturer to come do yearly inspections as needed to maintain the roof and to a lesser extend the roof warranty. One sheet of paper will do NOTHING to make the roof leak free. But incorporating contractor and Manufactures Best Practices into our 12 Year Building Management Plan should go a long way to remaining leak-free at the lowest overall total install + maintenance cost for the next +50 years! THIS is our goal, not having a limited warranty. We have one now from JP Stevens - DOW for a TPO that was installed 12 years ago, and if one has any real roofing experience, they can advise what this warranty is worth...
Sorry for long post, but I DO understand it's the product - application - maintenance that makes a difference. So seeking input on HOW we can improve our plan detailed above. Thanks for your time and consideration!
