METAL ROOFS

Some of the longest lasting roofs.

Metal roofs are long lasting, lightweight, and easy to install.  Unfortunately, they require maintenance and can be costly to repair.  Luckily, metal roofs can be coated in both silicone and acrylic based coatings depending on your needs.

Overview

Metal roofs are one of the best roofs for Hawaii. Most metal roofs can be easily repaired and made to last the lifetime of the building.

If you want a new roof we recommend local manufacturer HPM who has serviced Hawaii for decades.  We also use Kloeckner Metal (formerly MacSteel) for both standing seam metal roofs as well as standard corrugation.

LeakMaster's Opinion

The one thing you have to watch out for on older roofs is rust.  Most rust can be stopped with NXT Metal Primer if its not too far gone. These can also be topcoated with a silicone, which come in a white, grey or tan color.  If you desire more custom colors for design reasons, we use NXT Cool Coat which will reflect UV sun rays and keep the interior of the building cool, even with dark colors.

Pros & Cons

Pros

  • Standing seam metal requires very little maintenance and looks beautiful

  • Standing seam metal doesn’t have exposed fastened that can back out, or rust out

  • Their Kynar paint finishes are very durable

Cons

  • Standing seam roofs cost more than regular corrugation, which has exposed fasteners which can rust

  • Corrugated roofing, if not coated, will rust over time.

Calculations are estimates only. Additional materials may be required dependent on roof condition and other factors.

Step 1

Clean and let your roof dry completely! We suggest using a mild organic cleaner and a pressure washer if available, if not a hose and hard bristled brush should get the job done. CAUTION, metal roofs can be incredibly slippery.

Step 2

Reinforce and seal any weak areas and seams in the roof, as well as your hip and ridge grouting and any exposed fasteners. We recommend any acrylic roof mastic, and metal peel and stick tape.

Step 3

Prime with a metal etching primer, such as NXT Metal Prime.  Do not apply if it is expected to rain within 4-5 hours. If using NXT Metal Prime, be sure to apply top coat within 24 hours for best adhesive performance.

Step 4

Once roof is primed, again making sure it is dry, apply desired top coat according to product instructions. There are many options with many benefits. Do not apply if it expected to rain within 1-2 hours.

Your newly coated roof should last for many years if applied properly.
