Gutters aren't the most exciting part of your home, but they're protecting your foundation, your fascia, and your landscaping from concentrated water runoff. Mililani Roofing & Maintenance installs seamless aluminum gutters custom-formed on-site from continuous coil stock. No factory seams means no seam leaks.
Hidden hangers screwed into rafter tails or fascia boards every 24 inches maximum. No spike-and-ferrule hardware that loosens over time. Proper pitch at one-quarter inch per 10 feet toward each downspout outlet. These details are what separate gutters that work from gutters that overflow.
Our Gutter Installation Process
Gutter Assessment
We inspect your current gutters and fascia, measure your roof's effective drainage area, and calculate the gutter size and downspout placement needed to handle Mililani's rainfall. You get an honest recommendation, repair or replace.
Seamless Gutter Forming
Coil stock fed through our forming machine produces a seamless gutter to the exact measurement of your fascia. Custom miters, end caps, and outlet drops fabricated on the spot. Your color, your length, formed right in your driveway.
Precision Hanging
We hang with hidden hangers. No exposed hardware. Each hanger is screwed through the fascia into the rafter tail for maximum hold. Gutter pitch checked with a level at every section. Downspouts placed for optimal drainage away from the foundation.
Cleanup & Test
After installation, we run water through the system to verify proper flow and check for leaks at every connection point. Old gutters removed and hauled off. Job site clean.
