How to Choose the Ideal Metal Roofing for Coastal Climate

by Lily Carroll

Are you fortunate enough to have a home that's near the ocean where you can sit and relax to the soothing ocean sounds? If so, you need the right metal roof that can withstand the climatic conditions at the coast without curtailing your peace of mind. The combination of humidity and salt in coastal areas can corrode and damage some types of metal, and this can affect the appearance and performance of your roof. Here you will learn some useful tips on how to choose the ideal metal roof for the coastal climate.

Choose aluminum over steel

Aluminum and steel are the two common metals that are used for manufacturing roofs. When maintained properly, aluminum and steel roofs can last for decades. However, when it comes to the coastal climate, you should choose aluminum over steel for your roof. Aluminum is not prone to rust as is steel. When aluminum is exposed to the air, it forms an oxide layer which creates a thin barrier that is highly effective against humidity.

Besides choosing aluminum for your metal roof, there are measures that you can take to improve its performance in a salty and humid environment. Aluminum can be taken through a chemical process known as anodization. When it is anodized, the oxide layer formed on the surface becomes thicker, and this increases its resistance to corrosion.

Finish with powder coatings

When finishing your metal roof, go for powder coatings instead of liquid paint. Liquid paint can peel off when scratched or exposed to physical impact, and some paints tend to fade over time when exposed to the sun. On the other hand, powder coatings are durable, resistant to scratches, and they do not fade when exposed to solar radiation. Unlike liquid paint, you may not have to refinish your roof after every few years to maintain its appearance and protect the metal from the elements.

Find wind resistant fixtures

Coastal areas are bound to experience storms once in a while. If your roofing fixtures such as the shingles aren't wind resistant, you will be faced with the task of replacing them often. Your roof can also start to leak when the fixtures become loose or come off in the wind. To avoid the headaches and the cost of fixing your roof every time there is a storm, choose roofing fixtures that are sturdy and resistant to storms and hurricanes.

Besides choosing the ideal metal roof for your coastal home, make sure that the installation is carried out by a professional roofing contractor. They can also help you find the best product that will withstand the coastal climate.
