Roof access on third floor coming up to a TPO roof with multiple plumbing vents witches is hats and thaler. Thaler drains. 6 to 9 feet of the entire perimeter of the roof is metal flashing with metal venting.
Interior Condition, Leaks, Insulation, Roof Deck Type
Collect pictures to help depict the issues presenting on the interior of the building, if accessible collect images of any below deck insulation and the roof deck type.
Visual inspection of room 301 centre of the building
Corner room on the third floor 12 feet from the edge you can see the water staining following the wood joice
Attic/Crawl Space Inspection
Check vent/insul/deck/struct/plumb/wire/pests/moisture. Note damage, leaks, ventilation, & insulation. Photo any issues
No attic or crawl space, from third floor right to roof tpo roof
Exterior Roof Inspection
Exterior roof inspections assess the visible condition, including damaged shingles/tiles, leaks, flashing, and gutters. Flat roofs require close membrane scrutiny: blisters, cracks, seams, and ponding areas. Check for rot, mold, structural issues, ventilation, and chimney condition. Document findings with photos, noting membrane type and condition. Prioritize safety and thoroughness.

Exterior Roof Materials
Meticulous documentation of the existing roofing system is essential. For color, capture well-lit photos from various angles, noting manufacturer and color names. If unknown, compare physical samples to color charts under natural light. A cut test requires careful removal of a small section, noting material layers, thickness, and degradation. Photograph the cut and surrounding area, recording markings. Additionally, document insulation type (fiberglass, foam, etc.) and thickness. Record fiberboard composition and condition (water damage, delamination). Specify the vapor barrier type (polyethylene, kraft paper) and condition (tears, punctures). During the cut test, examine underlayment and roof deck type (plywood, OSB, etc.). Ensure thorough documentation of all materials for accurate matching and assessment.

Metal vents and drains are Thaler
Overall inspection of the roof, professional opinion determination to redo the roof in a different system other than TPO
