Environment Friendly Alternatives to Lead Flashing
Adequate drainage system for the roof is necessary to ensure continued maintenance and long life of a building. Generally flashing is used to prevent the entry of water into a building through an angle or joint in the roof. The most common flashing is lead flashing, which is used mostly because of its durability.
However, lead is a highly toxic substance even in microscopic quantities. It can even enter the body through skin contact and causes a wide range of extreme health conditions. This includes asthma and learning disabilities in children, kidney disorders as well as kidney failure and various types of nervous system disorders.
Therefore, it is highly advisable to use a suitable lead flashing substitute in the construction of buildings. Aluminium based flashing is an environment friendly alternative. It is just as effective as lead flashing in keeping water away from seams and joints and good quality anti-corrosive agent treated aluminium flashing is extremely long-lasting as well.
