DEPTCOR

The roof and its components were inspected on section 13 of the building known as Central Administration. The mechanically attached EPDM stairwell roofs appear to be in poor condition at approximately 20 years of age. Several defects were noted through out the roof including delaminated flashings at all roof penetrations, damaged roof membrane and delaminating field seams. The roof has the potential to last up to 2 more years with the recommended repairs performed. A new roof should be considered within in the next two years.

The costs shown for the roof replacement, restoration and alternate specifications are for the purpose of budgeting only and may be subject to change.

The replacement specification is to remove the existing roof and replace with like system.

The restoration specification is to cover the existing roof with 1 layer of insulation and a fully adhered EPDM roof system.

The alternate specification is to remove the existing roofing and replace with a fully adhered EPDM roof system at a cost of: $201,600
