Hawaii Metal Roofing: 5 Easy Tips For Ensuring Your Roof Lasts


No roof lasts forever. But in Hawaii, metal roofing that’s kept in good condition can last for decades. It’s not uncommon for a metal roof to offer reliable protection for 50 years or more. That’s saying something given Hawaii’s wet, corrosive climate.


Compared to other roofing materials, such as asphalt, wood, and shake, metal roofing requires much less ongoing maintenance. That’s one of the many advantages of investing in a metal roof. Having said that, here are five simple things you can do to prolong its life.


Tip #1: Look For Loose Screws And Tighten Them


Thanks in part to Hawaii’s trade winds, particularly during the winter months, screws on your roof can loosen, leading to loose flashings, fasteners, and panels. That in turn can set the stage for moisture intrusion and corrosion.


In Hawaii, metal roofing should be inspected every few months. If you notice loose screws, tighten them immediately.


Tip #2: Keep The Panels Clean


Keeping the panels clean is more than just a matter of aesthetics. It can lengthen the life of your roof. Dirt and moisture, allowed to accumulate unchecked around the seals and seams, can lead to the growth of mold and algae. Both, combined with Hawaii’s wet climate, can open the door to rust.


Tip #3: Examine Sealants And Replace As Needed


Sealants can break down over time, and compromise the seal between the panels and the underlayment in the process. When this happens (or ideally, beforehand), they need to be replaced.


During your periodic inspections, keep an eye out for signs that the sealant needs attention.


Tip #4: Remove Accumulated Debris


In Hawaii, metal roofing seldom accumulates a significant volume of leaves, branches, and other types of debris. Its sleek surface allows for such things to fall off the sides, with help from the wind and rain.


Occasionally, debris can get stuck, when this occurs it’s important to clear it away. Debris can trap water in the seams of your roof, leading to rust and possibly allowing moisture to penetrate the panels.


Tip #5: Clear Out The Gutters


Some of the debris that falls off the side of your roof will land in your gutters. This can become problematic if the buildup causes a blockage. A blockage will prevent water from draining out of your gutters, which in turn will prevent the edges of your roof from drying out.


When you inspect your roof, examine your gutters. If you notice leaves, twigs, pebbles, and other debris, clear them out.


Given the climate in Hawaii, metal roofing is your best option when it comes to protecting your home from the elements. Invest a little bit of time every three months to inspect and maintain it. You’ll be rewarded by a roof that can literally last a lifetime.
