Custom Metal Roofing
Custom Metal Roofing
It’s hard to settle on a single reason why HPM’s Custom Metal Roofing reigns supreme. Is it the innovative construction technology, the years of experience we’ve spent perfecting roofing design, or the exceptionally strong, sustainable materials we use to manufacture each roof? Maybe it’s the meticulous installation process and the exceptional service that make our metal roofing supply customers so happy. Whatever the cause, one thing’s for certain: You’ll have a roof that outlasts expectations.
Superior Technology
We pioneered Custom Metal Roofing in Hawai'i in 1963, and have a deep understanding of everything that goes into it. Our customers have long relied on us to provide efficient, quality metal roofing products to meet their diverse needs.
Why HPM’s Metal Roofing?
Decades of Experience
We’ve been a leader in metal roofing for more than 60 years, offering extremely competitive pricing, expert roofing personnel and the equipment and systems to provide accurate, on-time delivery.
Sustainable
Our metal roofing panels are made with the highest recycled content of steel and aluminum, allowing for metal roofing and other metal construction products to be routinely included on listings of green and sustainable building materials.
Energy Efficient
Our Custom Metal Roofing features Durapon70 heat-reflective finish that reflects more of the sun’s rays to keep your home cool.
Variety of Colors
Choose from many different Custom Metal Roofing colors, including metallic and exotic finishes. Durapon70 provides excellent color retention and resistance to chalking and fading.
Custom Metal Roofing Profiles
Fasten-through panels are manufactured to your exact lengths and specifications at HPM’s production facility in Keaau and delivered to your jobsite. They’re fastened with exposed color-matched screws that penetrate the metal roofing and secure to the purlin or sheathing. In general, fasten-through panels are less expensive than Standing Seam panels.
HPM manufactures the Standing Seam right on your jobsite using a portable roll-former. This enables each panel to be produced to exact measurements as specified in the field as the contractor installs. Standing Seam panels are fastened using screws or concealed clips, and the ribs are engaged by either snapping together or mechanically seaming. Curved and tapered treatments are available to match unique architectural designs. Photovoltaic solar panels can be easily installed on standing seam roofing using clips instead of penetrating screws.
