Roof Penetration Inventory
Record every vent, pipe, mount, and antenna.
Keep the Roof Penetration Inventory brief focused on plumbing and exhaust vents; chimney, skylight, and roof hatch; antenna, satellite, or service mount; future solar or equipment plans; each flashing and trade owner. Every Roof Penetration Inventory line needs a known condition, a remaining uncertainty, and a named person responsible for the final answer. Stay on the ground or in a safely accessible interior area. Roof access, destructive inspection, and installation belong with qualified people using proper protection.
Planning factors
Five decisions worth documenting
Use the headings as a proposal check. The actions beneath them are specific to this project decision.
Plumbing and exhaust vents
Mark plumbing vents and exhaust terminations on a roof plan using qualified inspection. Do not infer every pipe’s purpose from a ground-level silhouette.
Chimney, skylight, and roof hatch
Record chimneys, skylights, hatches, and curbs with model or construction information where available. Each interrupts the water-shedding surface differently.
Antenna, satellite, or service mount
List antennas, satellite dishes, service mounts, and abandoned attachments. Ask who removes, relocates, reinstalls, or closes each connection.
Future solar or equipment plans
Discuss future solar or equipment before the new covering is installed. Planned access and attachment coordination can prevent avoidable later penetrations.
Each flashing and trade owner
Assign every flashing and connection to a responsible trade. The inventory is complete only when the proposal explains both active and removed penetrations.

Before authorizing work
What record belongs with “plumbing and exhaust vents” before work begins?
Request a dated description and the evidence supporting the proposed treatment. Cross-check entries: chimney, skylight, and roof hatch; antenna, satellite, or service mount. Named responsibility: future solar or equipment plans. Closeout file: each flashing and trade owner. Identity check for Roof Penetration Inventory: confirm the business, applicable County license, roofing insurance, and current Harrison permit steps separately.
