About this file
This is a roof inspection report for Ralph W. Emerson Elementary/Middle School in Detroit, Michigan, prepared by Detroit Public Schools on June 10, 2026, following a visual inspection conducted on May 12, 2026. The inspection evaluated the remaining service life of the existing roof systems across 31 distinct roof areas (A through EE) to inform replacement planning and budgeting decisions. The report identifies that roof areas installed in 2017 utilize fully-adhered TPO membrane systems, while older roof areas installed prior to 1999 consist of 4-ply hot asphalt with aggregate surfaces, smooth 4-ply with aluminum coating, or in one case a 2019-installed EPDM membrane. The inspection reveals widespread deterioration issues including ponding water caused by inadequate slope, wet cores indicating moisture intrusion, membrane splits and holes, open flashing, and severe membrane deterioration. The report does not specify response dates, due dates, site visits, or bidder meetings, as it is a diagnostic inspection document rather than a solicitation notice.
The report recommends full roof replacement for 24 roof areas (E, F, G, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Z, AA, BB, CC, DD, and EE) with removal down to the structural steel deck and installation of R-30 insulation systems with fully-adhered 60-mil EPDM membranes eligible for 20-year warranties, at an estimated construction cost of $675,000. An additional six roof areas (A, B, C, D, H, and Y) are recommended for aggressive preventative maintenance at an estimated cost of $10,000. The total estimated construction cost for all recommended work is $685,000. The report serves as supporting documentation for the related state and local contract opportunity 27-0052 FMP Series 6 Roof Replacement for Cass Tech and Emerson facilities in Michigan.

EXECUTIVE SUMMARY
On May 12, 2026 a visual inspection of the existing roof system was performed. The purpose of this inspection was to determine the estimated surface life left of the existing roof system. Roof
Areas A, B, C, D, E, H, I, J, K, L, M, N, O & Z existing systems consisted of a fully-adhered TPO.
Roof Areas F, G, P, Q, S, T, W, X, Y, AA, BB, CC & EE existing systems consisted of a 4-ply in hot asphalt with an aggregate surface system installed prior to 1999. Roof Area R existing system consisted of a fully-adhered 45-mil EPDM roof membrane installed in 2019. Roof Areas U, V, & DD existing system consisted of the smooth surface 4-ply with a aluminum coating, installed prior to
1999.
Note: TPO areas are failing due to ponding water caused by lack of slope. Many of the cores taken were wet.
Recommendations:
Roof Areas E, F, G, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Z, AA, BB, CC, DD & EE: Remove existing roof systems system down to the structural steel deck. Install a R-30 Insulation system with a fully-adhered 60-mil EPDM membrane. This system is eligible for a 20 year warranty.
Roof Areas A, B, C, D, H & Y: Aggressive preventative maintenance
Estimated Construction Costs:
Roof Areas E, F, G, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Z, AA, BB, CC, DD & EE: Full replacement with a R-30 Insulation System with a fully-adhered 60-mil EPDM: $675,000.00
Roof Areas A, B, C, D, H & Y: Aggressive preventative maintenance $10,000.00
ROOF PLAN:
Note: Remaining life of existing roof systems is based on the estimated age of the roofs, visual inspection and assuming no maintenance being performed. Preforming repairs to roof areas that are red will not add any years to the roof life. It will only stop the current problem.
