Lead flashing is the preferred solution for many roofers and homeowners for a number of reasons.
Lead possesses a number of attributes that make it ideal for use in flashing. It is inherently resistant to corrosion, making it highly durable in exterior settings exposed to the elements.
Another significant benefit of lead is its malleability. This soft metal can be easily formed into different shapes based on the particular requirements of the roof design. In addition, lead is not flammable, an important consideration in areas prone to lightning strikes.
Lead is also aesthetically pleasing. Its soft, silvery grey finish is colour-compatible with many of the materials used in housing construction such as concrete, asphalt shingles, brick and glass.
One last thing to consider with lead roof flashing is that this material is somewhat heavy. Because of this, the installation of any lead components must be done correctly by qualified roofing professionals.
Considering that the average lifespan of a roof is twenty years, it makes sense that as much consideration is given to the roofing components, such as flashing, as to the quality of the roofing material and the qualifications of the roofing professionals to whom this important project is entrusted.
