Lead system
Lead has been used in the roofing industry for many years. It’s mainly used for weathering chimneystacks, flat roofs and turrets. It’s available in different weights and sizes. The weight is determined by the thickness of the lead. The thickness of lead will be specific to that roof. Each roof is different and will need a different thickness. Lead can only be installed in maximum lengths of 1.5m. This is due to the movement of the lead as it expands or contracts during warm or cold weather. If it’s installed on a flat surface of timber mop sticks or welting is required. All lead is treated with patination oil to prevent staining to other materials.
