Costco‘s existing EPDM roof system with over 150 skylights was nearing the end of its lifespan.


Incorporating a new roof system with so many skylights can make waterproofing a tricky business. Costco relies heavily upon their facilities to do business and cannot live with leaky roofs damaging inventory and turning away business.  Costco was looking for more than just a roofing contractor. They were looking for a partner that could provide condition reporting and consulting design to capitalize on return of investment.


Roof & Building Service performed inspection analysis, condition reporting, consulting solution design and project management for this client.


Roof & Building Service was able to offer significant cost savings to Costco by providing a recovery system that delivered them a quality project outcome. Throughout the project, Roof & Building Service prepared consultancy site reports for quality assurance at every stage of the project.
