Onoff Posted November 22, 2018 Share Posted November 22, 2018 1 hour ago, PeterW said: And then what on top..?? How are they detailing around the rooflights..?? Usually a 45deg fillet at the base of the upstand then an inch thick or more up the sides with a wrap of expanding mesh to support if you feel the need (not essential but do so on a steel post). Needs to return into some form of rebate / tuck in the top. Sides sometimes straight not tapered. Nice lead cap to finish off. ...imho Done a good few plinths like this over the years but always subbed out the asphalting. Top of lead cap usually 6" off of main roof. As the Welshman says, never lost a patient yet! Only got a Sharpie on me... 1 Link to comment Share on other sites More sharing options...

Only difference would be the upstand ( still have the fillet ) would be thinner otherwise walk on glass frames won’t fit . That was his suggestion.

Pocster Posted November 22, 2018 Author Share Posted November 22, 2018 (edited) Also , which I didn’t realise the hot bitumen isn’t bonded to the concrete ! ? This was to allow for any movement and prevent cracking . As for the parking area he said cover in polythene and just cement pavers ontop . He did indicate UV was the biggest problem ; but as mine is entirely covered not an issue . Edited November 22, 2018 by pocster Link to comment Share on other sites More sharing options...

(Not in THAT sense...unless he's minted! ) You can mitigate UV damage by painting on solar reflective paint direct to the asphalt. I'll take a pic of a can if I have one. 1 Link to comment Share on other sites More sharing options...

Pocster Posted December 16, 2018 Author Share Posted December 16, 2018 (edited) Right ! SIG guy recommended roofer . Roofer guy recommended guy to screed a fall . The screed has been done ; I can’t walk on it but looks to be a proper job . Problem is 1 up stand in particular is low - real low . Maybe just 20mm above the screed . Bearing in mind hot bitumen has to go ontop the screed so the upstand will be even lower . I know upstands are meant to be a min of 150mm but that was always impossible in this situation . I could timber across all the upstands to raise them before the bitumen . But then I’ll be much higher than the house damp course and much higher than the street entrance way . ? Trying to think how to make a ‘feature ‘ out of a raised corner ( stilted tiles sitting around glazing ) . Or just not worry - see what happens . The screed does look spot on fall wise so perhaps it’s less of an issue than I imagine . Just when it’s meant to be 150mm and I will struggle to get 15mm I worry .

Pocster Posted December 16, 2018 Author Share Posted December 16, 2018 (edited) Hey @Onoff ! Suppose I fitted this 1 walk on glass frame before the bitumen . Could he bitumen too it ? Essentially embed it in the bitumen ? . Then he could fillet away from it on each side . Hope that makes sense !?

Pocster Posted December 16, 2018 Author Share Posted December 16, 2018 Actually that might be a dumb idea and cause other issues . i did consider raising all the up stands but then the gates would also need a rising hinge or something to clear the driveway !! ?

Onoff Posted December 16, 2018 Share Posted December 16, 2018 I'm lost...aren't you having block paving atop the asphalt? With the top of the glass level with top of the blocks? Need a section view to remind myself. Link to comment Share on other sites More sharing options...

Too be fair his screeding is like perfect !! Can't help feeling that should have "tuck" on all 4 sides of the upstand. As if you'd put say a 20x20 batten around the shuttering before you cast it. Something for the asphalt to key into. Like my little hand sketch a while back. Then you bed the skylight on whatever goop you're using. Link to comment Share on other sites More sharing options...

He also suggested the screed to falls . i’ll try to get him back out to take a look ... Edited December 17, 2018 by pocster Link to comment Share on other sites More sharing options...
Mr Punter Posted December 17, 2018 Share Posted December 17, 2018 Should you run a course of brickwork around for the bitumen to dress up, or does this upstand get done in timber? Make sure the detail is OKed by SIG. I used adjustable pedestals from Castle Composites but the minimum height is 30mm. They also do fixed height ones down to 10mm.
