Sheet lead flashings in roofing applications

Friday, 26 February 2016

Sheet lead remains a commonly used roof flashing material in modern home construction and plumbing practitioners need to ensure they select the right lead for the job.

Sheet lead needs to be a minimum thickness of 1.7mm, which equates to approximately 20Kg/m2, as per Table 8.1.2 of SA HB39:2015 – Installation code for metal roof and wall cladding.

Where roof tiles are to be flashed by apron lead, the lead is to be dressed to suit the contours and cleats of the tile and must have a minimum cover of 150mm.
