    Default name of roofing material

    What do y'all call this type of roof? I was calling it Brie years ago, and a roofer told me that it wasn't a Brie roof. I now call it rolled asphalt, but maybe there's a better name.

    Looks like modified bitumen. And I believe you want to see more adhesive gooshing out (technical term) along the seams.

    Okay, WTH you talkin' 'bout?

    I did some searching and came up with nothing definite on the internet, what is "Brie" roofing?

    Common modified bitumen roll roofing

    Bit-Mod

    yes the seams seem a little weak

    isuslly indication of a 2 layer installation if probably ofset on a good day u can see or feel the overlap of the seam of the underlayment somewhere in between near the missle of a top sheet... kinda where it should be if done right

    seems can be improved by the addition of some more roof pitch on the seams

    You sure it is modified bitumen?

    What little I found on the internet suggested it was a type of torch down.

    With torch down, you would not see the run out from the laps as you would with a hot mop as there is no excess "hot mop asphalt" being pushed around and out.

    However, is Brie a brand name, or a local name applied to torch down (which was modified bitumen) or was it not even torch down?

    Is it like BUR, which is an abbreviation for built up roof, in that Brie is an abbreviation for (whatever)?

    From pic looks like rock-impregnated bit mod. Depending on manufacturer rocks are finer/tighter or bigger/wider. Or maybe it's just crappy roll asphalt.

    I think Brie is a brand name of a torch down roof product. This stuff is also torched down, but it's a different company. I have to call the roofer for my project soon anyhow, so I'll see what he calls the stuff when I talk to him.

    That actually looks like mopped down mod bit, or correctly termed SBS granulated modified bitumen.

    Looks like regular rolled asphalt roofing. The seams look very professional. It is what is between the two pieces that count.

    By the way, I didn't post the Brai site because I think it is a Brai roof, but only because I suspect Brie=Brai.

    I've always called it rolled mineral aggregate roofing.

    It's Mineral Surfaced Roll http://roofing.owenscorning.com/docs...nstall_msr.pdf

    I don't know of the newer stuff but when we applied it back in the day the life span was ten years.

    Brai was and is still mfg by U.S. Intec. It comes in several forms of product.

    US Intec Website


    This does NOT appear to be Brai. This appears to be 90 lb. mineral-surfaced rolled roofing.

    Modified bitumen, otherwise known as a "torch down" roof, after the manner in which the edges are "sealed".

    Not quite correct, partially correct, but that is like saying that all birds are ducks because ducks are birds.

    Modified bitumen is NOT "torch down", but "torch down" would be an installation method for "modified bitumen" if the product was designed that way.

    Most mod-bit that I have seen has been hot mopped down, very little has been torch down.

    I think I would agree for residential work until the past 5 years or so. Tar kettles now sit idle and cold, while the torch and portable propane tank have been hard at work.

    I call it a granulated cap sheet. Roofers that I know can identify the various types by the width of the roll, the thickness of the material and the amount of asphalt at the seams. Me? I dunno...

    Sorry but i beg to differ....

    even with the torch down typ usually one would see a little more squeeze out than what's there

    This type of roof is very common in our area one brand made by Soprema dpoes require a mechanically fastened underlayment.

    True our climate here is much more harsh

    bit-mod or maod bit...... I say Tomato u say TomAto

    whatever
