djcdan Posted July 14, 2021 Share Posted July 14, 2021 The roof system we're using recommends Wakaflex lead free flashing for detailing around GRP valleys. However Wakaflex seems incredibly dear in comparison to other lead free adhesive backed flashing on the market. Has anyone used these cost effective alternatives and had a positive experience. Ultimately I want the roof to perform as expected and want to ensure that these cheaper solutions, such as this (https://www.lbsbmonline.co.uk/lead-free-flashing-5m-roll-smooth) won't fail over time. Any thoughts? Link to comment Share on other sites More sharing options...
PeterW Posted July 14, 2021 Share Posted July 14, 2021 Difference is Wakaflex has elements of flexibility and stretch that the others don’t have. The others have an aluminium mesh in the centre of layers of PIB or other flexible waterproofing materials which means the material won’t stretch as much. Few also have the self adhesive backing.
