hot rubber

hello to all,(first time/ long time) i'm working on a hot rubber roof on which a green roof will eventually be placed.i'm wondering if many of you have had experience with this type of roof.i know i've seen green roofs discussed on the forum before but don't know how to retrieve the links!.My query is concerning the protection board placed on top to protect the membrane from foot traffic and u.v. rays. Do you guys lap it (as per the manufacturers data sheet) or do you go seam to seam as per our reps instructions.

thanks Vaa,yea thats the stuff and we use a crafco hot oil kettle as you described (heated at 350 degrees)which has been giving trouble the last few days. :( .Interesting that you say there were problems with the system and as I had not seen it before I was curious if many on here were familiar with it.My own experience with commercial systems is limited but a few of the guys on the crew claim to have installed it before mainly in Florida.It will be well seperated and protected from the soil and elements in general.The flood test will be interesting :silly:

hi to all,and thanks,sorry for not getting back sooner,yes it is rubberized hot mop or hot fluid applied although we also refer to torchdown as "hot rubber" which is confusing because when i worked in new york they referred to epdm as rubber, :unsure:thanks Vaa for the photos,true craftsmanship,neat to say the least, I know what you mean about the project management bit, its a full time job to keep other trades from making holes in the deck.Fortunately this is a conc. deck and no penetrations this area(apart from drains/overflow),its my/our first time with this system so thats always a little nerve wrecking.Anyway our issue has been resolved thanks to the inspector meeting with the owners engineers who are a pain needless to say,(know-it all but know little)I was wondering if many on here have experience with this system.After the protection board goes down we have insulation sandwiched between mira drain protective mat and also weed-barrier so we should be safe from damage,naturally a water test will be performed before we proceed to that stage.After all that its stone at the perimeter and topsoil the remainder. I'll get some pics up when I get time. :woohoo:

I don't have to admit it; it gives me great pleasure to admit it. I assure you I quite willingly I admit it. Great guy, great work. Have enjoyed every minute.

I'm not at all convinced he is referring to torchdown. I'm thinking it may be rubberized hot-mop.

Very clean Vaa,Good work..
