Roofing Lead, Lead Shingles , Panels - Lead Sheet Roofing
Lead is one of the most traditional and durable metal roofing, lasting up to 200 years, when properly installed.
Lead has great resistance to atmospheric pollution. It also resists the affects of acid rain. Some roofing applications use this functionality to protect stone work, copings and cornices.
Lead oxidizes with exposure. It developers a patina that is insoluble in water. Rainwater runoff over a weathered lead roof carries little lead.
