Currently I create this by having two roof composites that together make the full flat roof build-up, the first being a totally flat timber deck with OSB and plasterboard the otherside, the second being the 1 degree sloped firring, insulation and EPDM finish.</P><P>I wondered if there was a way to create a roof composite to incorporate part of the element being on a sloped angle such that this could be one composite?</P><P>This would be useful to me because this would make flat roof skylights look cleaner as I will not need to create a second opening.</P> Sat, 18 Jun 2022 09:52:02 GMT ardy97 2022-06-18T09:52:02Z https://community.graphisoft.com/t5/Modeling/Flat-roof-composites-with-a-in-built-1-75-fall-slope/m-p/341647#M159692 <P>Hi All,</P><P>For my projects it is necessary for flat roof build ups to have a sloped element above the timber roof deck to ferry the surface water to a trough gutter.

I always have to split it. Set the skylight in to the flat element and then cut a hole in the sloped part. It would be good to be able to do this.&nbsp;</P> Sat, 18 Jun 2022 16:04:48 GMT https://community.graphisoft.com/t5/Modeling/Flat-roof-composites-with-a-in-built-1-75-fall-slope/m-p/341672#M159700 Lee Hankins 2022-06-18T16:04:48Z https://community.graphisoft.com/t5/Modeling/Flat-roof-composites-with-a-in-built-1-75-fall-slope/m-p/341717#M159708 <P>You could try using the opening tool to cut through both then add the rooflight as an object and complex profile beams to trim the opening inside&nbsp;</P> Sun, 19 Jun 2022 17:57:51 GMT https://community.graphisoft.com/t5/Modeling/Flat-roof-composites-with-a-in-built-1-75-fall-slope/m-p/341717#M159708 Tim Ball 2022-06-19T17:57:51Z
