What Types Of Metal Roofing Are Available?

Overview

Metal roofing is available in a number of colors, styles, and textures. The advantages to choosing one of the various types of metal roofing on the market are numerous. Metal roofing products are durable, fire-resistant, and lightweight. They are also recyclable.

A number of different metals have been used to construct metal roofing materials. Manufacturers have used aluminum, zinc, copper, steel, titanium, and stainless steel for this purpose. The most common material used is coated sheet metal.

There are two basic types of metal roofing on the market. The first type is known as structural metal roofing. The second type is called architectural (or non-structural). Please continue reading to learn more about the differences between each of these types of metal roofing.

Structural Metal Roofing

Structural metal roofing is attached to lathe boards and does not need any support underneath it. This type of metal roofing is available in a number of finishes, including painted, clear acrylic, and a mill finish.

Non-Structural Metal Roofing

With a non-structural type of metal roofing, the gravity load is transferred to the roof deck underneath it. The non-structural panels are available in styles that are manufactured to look like tile, standard shingles, slate, or wood shake. The non-structural metal roofing will likely be treated with a coating. This coating is designed to be both durable and pleasing to the eye. Customers have the option of choosing between a number of paint and stone finishes.

Low Slope Metal Roofing

It is not uncommon to see metal roofing used for factories and industrial buildings of all types. Special clips and fasteners are used when this type of metal roofing is installed to compensate for the fact that the roofing material will expand and contract with changes in temperature.

It is possible to install a metal roof over top of an existing leaky roof. If the worn-out asphalt shingles do not need to be removed and placed in a landfill site, then this is a better choice as far at the environment is concerned.

Maintenance

If you choose to install a metal roof, you are getting a product that is virtually maintenance-free. You may want to rinse off the surface with a hose or a pressure washer occasionally. This will help to keep the surface free of bird droppings. Generally speaking, algae developing on a metal roof is not a concern.
