Where a lead roof makes sense
Small flat roof areas, dormers, bay windows and porch roofs are all well suited to a lead covering, where the material's longevity justifies the higher upfront cost.
How lead roofing is laid
Lead is laid in individual sheets or 'bays', sized to allow for thermal expansion and contraction, with rolls and welts joining each section so the whole roof moves without cracking.
Longevity and maintenance
A properly installed lead roof can last many decades with minimal maintenance, though periodic inspection of the joints and welts helps catch any early movement before it becomes a leak.
