Metal roofing is one of the most durable and energy-efficient options for most residential homes. Compared to other materials, it has a longer lifespan and can withstand corrosion. While metal roof panels are rust-resistant, it is not 100% rust-proof. Factors like improper storage, poor installation, and other elements can cause rusting and premature staining.

Fortunately, there are several ways to avoid metal roof corrosion. Read on to learn helpful tips to ensure your metal roof won’t rust and age quickly.

Check for Stains Before Installation

Check the materials first before your roofing contractor starts working. Your metal roof panels might be mishandled during storage and delivery, so make sure to check them for any damage. In case there are signs of rust or dents, ask the metal roofing manufacturer for a replacement.

Use High-Quality Metal Panels

Get more bang for your buck when you choose metal panels with a certain amount of rust-resistant properties. With premium metal panels, you can enjoy years of use and trouble-free maintenance. Forget about sub-par panels! Using low-quality materials only means that a repair or replacement isn’t far down the line.

Galvanize Your Metal Roof

Liquified zinc can be used to coat and protect the roof from rust and corrosion. Galvanizing the metal roof extends its life span and strengthens it from harsh weather conditions like heat, snow, and hail. 

Moreover, a protective layer of zinc coating enhances its durability, lasting up to 50 years. When handled and installed properly, it can protect your home and everything in it. Expect to pay from $550 to $575 for a galvanized metal roofing project.

Paint Your Metal Roof

You might be wondering if you can paint your metal roof. The answer is yes, you can! A metal roof painted with zinc-rich primer is protected from moisture and aggressive corrosive environments. Simply clean and remove all dirt and debris from your roof, then apply a layer of paint with high zinc content. You are encouraged to repaint your metal roof to prevent corrosion and update its appearance.

Use an Elastomeric Roof Coating

This type of roof coating is 10 times thicker than paint and helps waterproof any surface. Elastomeric roof coating is acrylic seals that form an effective barrier against rust and weather for up to 5 years. Like paint, you need to clean the surface and remove any dirt before you apply the elastomeric coating. It comes in various colors that can match the exterior of your home.

Hire a Professional Roofing Contractor

The installation and repair of your metal roofing should only be done by a trained and experienced contractor. Climbing on a ladder to do the work is a dangerous job. Don’t put yourself in a situation that will cause you harm. A metal roof isn’t the same as roof shingles, so there will be differences in installation methods. Let a professional roofer do the job for you. They know how to handle metal roofing materials and ensure that rusting won’t happen.

Whether you need help with painting, installation, or elastomeric coating, only count on metal roofing experts. Some inexperienced contractors may cut corners and undertake bad practices. Protect your investment by putting your trust in the hands of skilled professionals.

Perform Regular Maintenance

While metal roofs require minimal upkeep, it doesn’t mean that you will no longer care for them. Routine maintenance should be performed at least once a year to avoid the buildup of debris and degradation. This will not only avoid corrosion but also prolong the life of your roofing system.

How Often Should You Reapply Metal Roof Coating?

In general, it is recommended to recoat your metal roofing 5 to 12 years after your installation. The duration depends on your home’s size, climate, and location. Ask a roofing professional if you think the protective coating needs to be reapplied to prevent further corrosion and oxidation.
