HPM Standing Seam Metal


Nanakuli, Hawaii

This roofing project was for an open warehouse facility located on one of HECO’s power plant locations on the west side.

This warehouse needed a roofing system that would be resilient enough to withstand disastrous weather conditions and hurricanes as the facility was being retrofitted to serve as a housing shelter for parts and materials for field transformers for the powerplant as a means of emergency preparedness.

As such, a higher than normal gauge for metal was spec’d for this project and the roof huggers had to be custom designed to secure a 105mph roof/wind warranty due to the unique location.

This project was under high security due to location on HECO powerplant premises. Perimeter warnings were set up all around and 100% tie off executed.

No safety monitors were on site due to that high security clearance. Cranes were utilized to load on the 50’ panels of the standing seam metal roofing.

This project required the custom fabrication of a special 22 gauge metal roofing as compared to standard industry which is 24 gauge.

As such roof huggers had to be custom designed and the entire roofing project had to secure a 105mph roof/wind warranty.

The large roofing panels required fabrication on site and installation of skylights and vents.
