About this file
This is a roof inspection report for Ralph W. Emerson Elementary/Middle School in Detroit, Michigan, conducted on May 12, 2026, to assess the remaining surface life of the existing roof system. The inspection identified multiple roof areas with varying conditions and ages, ranging from systems installed in 2017 to those predating 1999. The report details 31 distinct roof areas (A through EE) with specific measurements, heights, structural slopes, and drainage configurations. Key findings indicate that Roof Areas A, B, C, D, H, and Y, which consist of fully-adhered TPO installed in 2017, require aggressive preventative maintenance, while 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 require complete removal and replacement of existing systems down to the structural steel deck.
The recommended solution for the 25 roof areas requiring replacement involves installing an R-30 insulation system with a fully-adhered 60-mil EPDM membrane, which is eligible for a 20-year warranty. The estimated construction cost for full roof replacement is $675,000.00, with an additional $10,000.00 budgeted for aggressive preventative maintenance on the six areas requiring only maintenance. The inspection report identifies significant deficiencies including ponding water caused by lack of slope in TPO areas, membrane deterioration, flashing issues, fire damage, and holes in drain pan flashing. Multiple roof cores extracted during the inspection revealed wet conditions, indicating compromised system integrity and potential interior water infiltration.

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.
