Hi Kempo, u ever had to do a single ply roof with a curved (internal & external) upstand wall? if so how did u finish it a the upstand?

[kempouk]

@grac7228 i would mark a 100 mm line on the flat using a 100mm block and pen, then pre bend my up-stands and where the flat over lapped the pen mark i would cut the up-stand on the flat to this point and fit a but or joint strap.

you could end up with but or joint straps 100 mm apart so the curved up-stand so your up-stand would wrap around the curve but on the flat you would have v shapes in the up-stand that would require a butt or joint strap .

@kempouk

Thanks. I was thinking of having a flat piece of coated metal (175mm)bent around the curve and have the end of the flat sheet/s turned up the wall and weld onto the metal say 50mm as they're non fleece, with a lead cover flashing that covers the upstand weld. What do you think?

@grac7228 yea that would work, you could even do it your self by cutting the metal on the flat to form the curv, and where the cuts are just put a 100mm joint strap over the cuts to the top of the metal, this way you could use some off the shelf once bent trim.

the flashing on the pipe 120 mins in to the video... is that a non-reinforced tpo flashing split boost? or did u stretch or two piece it

[kempouk]

@griish i wrapped some un-reinforced around the pipe and welded that together, then on the flat i made the circle then cut the center hole 20 mm smaller than the pipe then warmed the center hole to form a flange.

then using the small attachment on the heat gun gently worked around the base welding the flange to the vertical wrap round.
