Premolded corners?

[grumpydasmurf]

What are your opinions on premolded/pre-manufactured corners for flat roofing?

Are you talking about in the corners inside the parapet walls? I've never done much of flat roofing.

[grumpydasmurf]

Yes. INside and outside corners for parapets, heck even curbs.

Like I said.. never done any flat roofing before. Typically isn't it done with the sheet goods - cut to form the rounded portion and overlayed with torch applied? Wouldn't it be quicker with premolded? I have no idea what I'm talking about though.. haha.

With torch applied yes it would. Even with a glue down SBS or APP it would... Same principal for modified bitumens. When we are talking single ply roofs it's a whole new ball game. I think the pre-molded pieces are intended for use on a single ply system.

I think quicker yes, but quicker isn't always better. Ther Versico rep was showing me when roofing with EPDM to just "pig ear" inside corners. This is basically just folding the roof over it's self and glueing down the loose flap. On a torch roof we'd cut off the flap but the Versico rep made a good point. No cut = no leak.

Makes sense to me.
