- The roof area is approximately 2500 sq ft or in roofing terms 25 “square”. Each square measures 10′ by 10′.
- It takes 280 slates, 8″ x 16″ to cover one square or over 7000 slates to cover the entire roof.
- Slate is much more durable and long-lasting than other roofing materials and is substantially heavier. The weight of slates on one square exceeds 700 lbs!
- All metal components on the roof are solid 20 oz copper.
- The flashings, valleys, ridges, hips, gutters, braces, brackets and drip edges are all custom made on site with specialized metal forming equipment.
- The profiles and shapes of the new copperwork are being replicated as near as possible to those original to the building when built in 1895.
- The chimney will be rebuilt back to its 1895 profile.
