ive heard guys talk about mars bars. is that from this system? i figured they weren't talking about candy bars.:laughing:

 

MARS Bar

That’s right – MARS Bar. Only one I ever saw that worked was on a barrel roof. I guess with enough slope anything will keep the water out. On a low slope roof candy bars may have worked just as well.

 

Carlisle MARS system or other?

Came across an older EPDM roof system this week that I could not definitively identify. May be a Carlislel MARS system but need verification. The roof is a 45 mil EPDM with 30' wide rolls, glued seams, installed with non-penetrating caps (2") that snap into under-membrane mechanically fastened plates (8"). 4 foot grid pattern.

Any clue as to manufacturer and vintage?

Thanks

 

Very close to the style I was talking about. Except instead of the little button things these had a plastic slider then another plastic lock for that. I will post some pictures of it monday when I get to the office. I have one of the attaching clips in the office.

 

I haven't seen that exact style of button before. Sorry. It is basically what we were discussing previously, however.

 

Used it a few times, but not a big fan.

Our company, Palm Beach Roofing used this system a couple times, but really weren't impressed. I guess it depends on the type of roof you are working with. Does anyone know a good safety system for us to try to protect workers from falling off the roof? We have to replace the one we have. Thanks.

 

Your company has been around since 1994 and you dont know what a good fall protection system would be? I guess ill bite and ask what kind of roofing you do? Depends on type of roofing and building styles, I would guess the a harness and lanyard with a ridge anchor, would be just fine.

 

He's just spamming his website.

 

Yeah figured as much.

 

that dosent lool like the Carlisle one, is there any name on the material, pipe boots etc.. that would be a clue. There were a lot of strange systems back then.

No batch numbers, date stamps or other markings on the membrane or any other item. I have one contact that believes this is an old Carlisle NP (non-penetrating) system. Different from the MARS bar and mushroom cap. Still haven't found any one that is absolutely sure of the system...still searching.

 

SingleSource was the ones who sold the products im refering too. Sorry still didnt get that pic up.

Ok finally took some pictures of the non penitrating roof clip things.

That's a very unique fastening system. New to me. Any idea when this system was installed?

The Argument for Appeal is a typical example of the games that get played in court. No one ever really seems to win in these cases except the lawyers.

 

Sigh, I hate when I preview post then move on instead of submit!

I beilve the roofs were installed in the early to mid 90's. These building are the only ones ive seen like it and they have 1000's of squares of it. I had heard that it was all out of towners that did the work and im sure thats not far off base as there is only a few contractors in our area that could manage a job of that size. I would guess of 90% of them need to be replaced as most have pulled from the walls and other leaks caused by the locks. As you can guess leaks can be a PITA with these. They seem to be worse in the winter and again the roofs have little to no slope on them.

I thought it was funny that after looking up single source the 2nd link was that to a law suit. Yes generally the lawyers are the ones who fair far better then any of the partys involved.

I will make sure to hit Submit Reply so I dont have to type this over again!

 

According to me, the best material, but a little expensive would be the rubber roof membrane. However, you have to make sure that you obtain a written agreement with the installer.

I prefer roofing membranes and synthetic rubber roofing compounds for flat roofs.

i said this on other replies on this thread i love my single ply too, as an installer, but do agree that coal tar pitch is the best roof. thing is almost nobody does them any more. cost, liability, and lack of knowledgble installers are making it a dinosaur. ive worked with alot of old timers on single ply jobs and theyre awesome til its time to start kicking out rolls, and god help me do any detail work. when i see that it keeps me motivated to not become a one sided roofer, cuz i dont want that to be me. who knows what it'll be like 20 years from now i'll probably have some young punk like myself saying the same sh--.

 

natural stone slates,hard work but it looks beautiful and solid

 

Not on flat roofs though.

 

I support that. Even though natural stone slates looks beautiful and solid its not suited for flat roofs.

I have been using mule hide self adhering roll roofing. I like the face it sticks down just as good as torch down without the flames

I find it easier to work with then epdm for flat roofs but some applications call for epdm when the roll roofing can not be used.

 

Duro- Last

 

At least that is what they say. :whistling:

 

Probably EPDM Single ply membrane.

Biggest seller of ours and we like it.

Either that or GRP

definitely EPDM or TPO

 

In my personal opinion I think that most of us like green roofing and reason is very obvious that it looks beautiful and create a green natural environment and have a soothing effect on the eyes.
