Your finished roof will always use more than its plan area: sheets must overlap so the seams can be welded, and the membrane also runs up parapets, kerbs and around outlets. Work out the roof in 1.05m-wide strips, add the seam overlaps and upstand heights, then add an allowance for cutting waste. For example, a 3m x 6m roof needs three 6m strips laid across its 3m width, about 18m of the 20m roll, before any parapet upstands or waste are added, so even a small roof can run close to a full roll and larger roofs need several. Measure your actual layout rather than dividing the roof area by 21.\u003c\/p\u003e\u003ch2\u003eBefore you order: what this is and is not\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMembrane only.\u003c\/strong\u003e The roll does not include insulation, vapour control layer, fixings and plates, seam cleaner, edge trims, outlets or detailing accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt needs a hot-air welder.\u003c\/strong\u003e The seams must be welded with suitable single-ply welding equipment by a trained installer, following the manufacturer's system instructions for temperatures, seam widths and fixing patterns.
