Project Details

PRC was retained by the client to perform an initial Roof Evaluation and offer recommendations for replacing the existing roof system on a four story office building located in downtown Portland, OR.  After a thorough evaluation, PRC was able to determine that the existing EPDM (Ethylene Propylene Diene Monomer) roof system had remaining service life and repairs could defer replacement for 3-4 years.  A scope of work was developed to repair the existing roof and presented within the report. 

In planning for the future replacement, the client was interested in exploring options for vegetative roof coverings to reduce the amount of storm water runoff and to provide additional outdoor space usable by the occupants.  PRC established design criteria appropriate to the facility and presented four roof replacement options with associated budget projections for the client to consider.
