TYPES OF STEEL ROOFING MATERIALS

ALUMINUM ROOFS

Aluminum is the most common option for a residential roofing system because of its lightweight, durable, and corrosion-resistant.

Pros:

● Rust free

● Comes from a large percentage of recycled material

● Energy efficient

Cons:

● More expensive than steel

● Not very hail-resistant

GALVALUME STEEL ROOFS

Galvalume is a coating of zinc, aluminum, and silicon that is used to protect a metal from oxidation. Galvalume steel is corrosion resistant which gives roofs a longer life span. However, with Galvalume steel you do need to worry about tension bend staining. Tension bend staining occurs when moisture or other corrosive elements make their way into the cracks of the roof panels and causes it to rust.

Pros:

● Corrosion-resistant

● Strong

● Relatively inexpensive

Cons:

● Receptive to tension bend staining

GALVANIZED STEEL ROOFS

Galvanized metal roofs are made of steel or iron and have a zinc coating to prevent rusting. Zinc is added as a protective barrier to prevent the base metal from corroding. This is one of the most common metals used for roofs since it is inexpensive, sturdy, and can last for a long time. However, Galvanized steel is not a good option for people living in coastal areas. The moisture in the air can speed up corrosion which will shorten the life of the roof.

Pros:

● Inexpensive

● Easy to customize

Cons:

● Doesn’t last as long as the other metals

● Install issues can lead to rusting

● Difficult to work with

SANGOBUILD STONE COATED STEEL ROOFS

Sangobuild stone coated steel roof panels offer superior durability, protection, and design that makes them the best choice in stone coated steel.

Sangobuild panels are made with ZINCALUME® which combines the corrosion protection of aluminum with the sacrificial protection of zinc, giving it the advantage of both metals. As a result, ZINCALUME® has a significantly longer service life than a galvanized steel product using only zinc.

Part of Sangobuild roof performance is due to its installation. Each metal tile is horizontally fixed into battens, which provides integrity to the entire roof and eliminates wind uplift issues.

Pros:

● Easy, fast installation

● Superior protection against wind, hail, and fire

● Lightweight

● Look like traditional asphalt shingles

Cons:

● Slightly more expensive than traditional asphalt shingle roofs
