01
Identify the reviewing authorities
Federal, state and local programs have different roles and submission requirements. Engage the preservation professional and program staff early.
02
Document significance and condition
Record original slate, patterns, dimensions, flashings and previous alterations. Demonstrate why proposed repair, selective replacement or full replacement is necessary.
03
Keep approvals aligned with construction
Substitutions, hidden conditions and mockup changes may require additional review. Maintain photographs, meeting records and approved samples through project completion.
