Roof Flashings & Lead

Roof flashing is vital to roof construction. Where a watertight junction is required where areas of the roof join, roofing lead is used. On a roof there are various elements such as pipes, chimneys, vents or roof configurations that do not come together properly. These require the use of flashing to ensure the areas are properly sealed to deflect rainwater. There are different types of flashing for different situations.

Flashing can be made from copper, aluminium, stainless steel, galvanised steel or lead. However, lead has many advantages over other materials. It is long lasting and extremely malleable. Rolled lead will last for the lifetime of a roof. Another advantage is that, if lead flashing has become badly corroded, it can be easily replaced as it is easy to handle.

Roof lead is also extremely attractive to look at. Although there are cheap alternatives to lead flashing such as plastic or UPVC, when it comes to durability there is nothing like using lead which can last a century or more. It is recommended for all types of roof flashings including chimneys, roof lights, stepped abutments and pitched or flat roof terminations.

Roofs are constantly exposed to weather and changes which reduce their effectiveness in time. Weatherproofing begins to decay and water seeps in causing damage to joists, timber and overall structures. This is where lead flashings can act as an effective sealant. All experienced builders will be able to supply and install lead flashing.
