Alto Lead from Mercury Building Products is a high performance low cost aluminium flashing suitable for use as an alternative to traditional lead in both flat and pitched roof applications.

Alto Lead is produced from sheet aluminium with a protective polyurethane coating on top and a polyisobutylene adhesive on the underside. Finished with a dimpled profile this unique construction ensures that Alto Lead is waterproof, durable and extremely malleable. The polyisobutylene adhesive ensures a strong permanent bond to all building materials without the need for a primer unless a surface is extremely unstable and forming a watertight joint requires no additional tape or sealant.


Alto Lead is extremely safe to use due to it's light-weight construction and cutting and shaping is achieved with a knife or scissors that produce no sharp edges. Consequently installation is rapid and safe with no health and safety issues. Alto Lead has a 15 year guarantee with a life expectancy in excess of 20 years. Alto Lead can be installed and worked in any direction using a mallet, roller or by hand. Cutting is achieved with scissors or knife.
