Clippert Academy Roof Inspection Report Summary
This document is a roof inspection report prepared for Detroit Public Schools' Clippert Multicultural Magnet Honors Academy located at 1981 McKinstry Street, Detroit, Michigan, dated June 10, 2026. The inspection, conducted on May 20, 2026, evaluated the existing roof systems across nine distinct roof areas (A through I) totaling approximately 27,652 square feet to determine remaining surface life and condition. The facility's roof systems vary significantly in age and type, ranging from pre-1999 installations including asphalt shingles and modified bitumen membranes to more recent systems installed in 2004 and 2024. The inspection identified severe deterioration across multiple roof areas, including compromised shingles, membrane blistering, deteriorated flashings, and failed penetrations documented through photographic evidence.
The inspection recommends full replacement of Roof Area A at an estimated cost of $115,000 and comprehensive replacement of Roof Areas B, C, E, F, and G with R-30 insulation and fully-adhered 60-mil EPDM membrane systems at an estimated cost of $340,000, eligible for a 20-year warranty. Preventative maintenance for Roof Areas D, H, and I is recommended at an estimated cost of $3,000. The total estimated construction cost for all recommended work is $458,000. Roof Area D, installed in 2024 with a fully-adhered EPDM membrane, requires only preventative maintenance. The remaining roof areas installed prior to 1999 have exhausted their serviceable life, and the report notes that repairs to severely deteriorated areas will not extend roof life but only address immediate problems.

EXECUTIVE SUMMARY
On May 20, 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
Area A existing system consisted of an asphalt granular surface architectural style shingle installed prior to 1999. Roof Areas B, C & E existing systems consisted of a modified bitumen granular surface system installed prior to 1999. Roof Area D existing system consisted of a fully-adhered
EPDM membrane installed in 2024. Roof Areas F & G existing systems consisted of a 4-ply aggregate surface BUR membrane installed in 2004. Roof Areas H & I existing systems consisted of an asphalt granular surface architectural style shingle installed in 2004.
Recommendations:
Roof Areas A: Full-replacement.
Roof Areas B, C, D, E, F & G: 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 D, H & I: Preventative maintenance
Estimated Construction Costs:
Roof Area A: Full-replacement with new asphalt shingles: $115,000.00
Roof Areas B, C, D, E, F & G: Full replacement with a R-30 Insulation System with a fully-adhered 60-mil EPDM: $340,000.00
Roof Areas D, H & I: Preventative maintenance: $3,000.00
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.
