About this file
This document is a visual survey report prepared by the State of Michigan Department of Technology, Management & Budget (DTMB) for the Muskegon Correctional Facility roof assessment. The report, dated January 5, 2023 (ATI Report No. P2225-001), contains photographic documentation and visual survey findings for roof conditions across multiple buildings at the facility, including the Administration Building, Housing Units 1-5, the Maintenance Building, and the Powerhouse Building. The survey documents the physical condition of roof systems, insulation, flashing, ventilation components, and structural elements through 42 detailed photographs organized by building section. The assessment captures existing roof configurations, material types, deterioration patterns, and repair history across steep-sloped metal panel roofs and low-sloped membrane roofs throughout the correctional facility.
The photographic survey reveals significant maintenance and repair needs across the facility's roof systems. Key findings include deteriorated paint coatings on aluminum metal panels exposing bare metal, displaced and inadequate insulation in attic spaces, failed soil pipe flashings allowing water entry, missing foam insulation panels, inconsistent roof modifications and repairs, asbestos-containing caulk at parapet joints, and various ventilation system deficiencies. Multiple roof sections show evidence of previous repairs with varying degrees of quality, including ridge vent modifications, valley flashing installations, and panel replacements using different materials and dimensions than original construction. The survey documents conditions that suggest the need for comprehensive roof restoration or replacement work to address performance, water intrusion risks, energy efficiency, and facility integrity concerns.

Appendix D1 – Visual Survey Photos (Administration Building)
ATI Report No. P2225-001 Date 1-05-23 Page 1 of 3
1. Administration Building. Main low sloped roof. General View. Frost on roof. Insulation fasteners shown.
2. Administration Building. Another general view of the main low sloped roof. No apparent heat loss due to wet insulation as frost is not melted.
3. Administration Building. Core #1 on main low sloped roof. Steel deck, 1.5” ISO and modified membrane roof.
Insulation found to be dry at core.
4. Administration Building. Core #2 on main low sloped roof at parapet wall. Wood blocking found. Insulation found to be dry at core.
5. Administration Building. View of narrow rib steel roof deck below main low sloped roof.
6. Administration Building. View of the metal roof panels on the north side. These metal panels are “newer” and have ribs at 16 inches on center.
Photographs 1-6
ATI Report No. P2225-001 Date 1-05-23 Page 2 of 3
7. Administration Building. View of “older” metal panels on south side and at east/west steep mansards. Ribs are at 12” on center. The older panels are losing their paint.
8. Administration Building. View of west mansard and the flaking paint. There is a securing camera over the entrance door.
9. Administration Building. The “older” metal panels were at one time “painted” and the added paint is flaking off and is especially visible at the west entrance door side.
10. Administration Building. The “east” steep sloped mansards have multiple rows of razor ribbon in place, as well as other security wires.
11. Administration Building. View in the attic showing the steel roof deck supporting the metal panels. Spray foam looks to be “added” at this valley location and is shown on the original construction drawings for “valley”.
12. Administration Building. Fiberglass insulation exists on the floor of the attic below the metal panels. Much of the insulation appears to be moved or displaced.
Photographs 7-12
ATI Report No. P2225-001 Date 1-05-23 Page 3 of 3
13. Administration Building. There are rectangular intake soffit vents below the metal panel roofs.
14. Administration Building. In the attics, the openings for the soffit events are visible in the building overhang. The overhang was not insulated.
15. Administration Building. Raised low slope roof near SW corner of building.
16. Administration Building. Raised low slope roof. Also, a modified roof. Slopes from west to east. No melted frost.
17. Administration Building. Raised low slope roof near SW corner of building. Roof Core #3. Core found an orange colored foam insulation that may be phenolic foam.
18. Administration Building. Raised low slope roof near SW corner of building. The parapet does not have a metal cap. The caulk joint from stone to brick is poor. Asbestos sampling of this caulk showed it as containing asbestos.
