Mixing Old-World Craftsmanship & Modern Building Science
The restoration of the tower of Independence Hall in Philadelphia has been a fascinating example of the National Park Service’s fierce dedication to preserving the building’s structural elements while supplementing and strengthening the historic site with modern building materials.
When the 14-month, $4.9 million project is completed in early 2012, its structural integrity will remain intact, preserved for future generations. Key to its rehabilitation is a complex repair and replacement of lead roofing, lead-coated copper flat seam roofing, ornamental flashing, and custom-made cedar shakes installed at various locations throughout the nine levels of tower roofing.
