Tips for Caring for Metal Roofs

One of the problems with metal roofing in Utah is rust. However, these roofs have been around for a while and come with an array of benefits. Metal roofs can withstand mildew, resist fire, and withstand weather extremities. Apart from these attributes, metal roofs are durable, easy to install, and affordable.

However, rust may be the only challenge that adds cost to the maintenance of metal roofs. Rust forms on metal roofs when moisture and oxygen contact each other, oxidizing the metal and making it weak. Rust can cause severe damage to a metal roof if left unattended for long. Fortunately, the following preventative measures can help homeowners protect their metal roof against rust:

Galvanization

The simplest way to galvanize metal roofing is to treat it with liquefied zinc. The zinc will form several layers of coat over the metal roof, which will protect it from rust and corrosion. Galvanizing a metal roof with zinc will also extend its lifetime and ensure that it remains protected underneath the coat for several years. Galvanization also toughens the roof for conditions such as excessive heat, snow, and hail, which can all cause corrosion and rust. Galvanized metal roofs are useful as they don’t require any other treatment to keep rust and corrosion at bay. After galvanizing a metal roof, no maintenance is needed, except for regular cleaning and painting as the need arises.

Coating

One way to prevent rust and corrosion on a metal roof is to coat it. The elastomeric layer contains an acrylic sealing system that roofers can apply onto a metal roofing to protect it from rust and corrosion. As with painting, builders have to clean the roof before applying the elastomeric roof. These coatings are available in a variety of colors to meet your unique needs.  With elastomeric coating, homeowners can enjoy changing the color of the roof to give it a new look and prolong its lifespan. A layer of elastomeric coating can last up to half a decade. However, homeowners might need to reapply their coat after every ten years if they decide to apply multiple layers.

Painting

Another way to protect a metal roof from rust and corrosion is to paint it. Use a primer with at least 80% zinc as it is excellent at preventing corrosion and rust. A primer rich in zinc works excellently if the roof is cleaned and prepared before application. Painting necessitates thorough cleaning to remove rust and dirt that may have formed on the roof.

Metal roofs are a popular choice for their longevity, strength, and resilience. However, rust and other reactions can sometimes cause problems to a metal roof and reduce its life cycle as well as its performance. Knowledge and awareness of causes of rust and corrosion can help homeowners mitigate these problems.

Understanding the potential pitfalls of corrosion and rust and how to mitigate them can help prolong the life of a metal roof. Simple measures such as galvanizing, coating, and painting can go a long way to eliminate the threat of rust or corrosion before it occurs. Experts recommend treating rust and corrosion before holes or cracks develop, but urethane roofing cement can help make patches if it is too late.
