An Overview of Metal Roofing Systems

Metal roofing systems are the subject of many frequent questions from home owners looking to choose a roof for their residence. This is more so in areas where metal roofing isn’t very common and where people consider traditional asphalt shingle roofing more durable and sturdy than metal roofing systems.

This limited exposure to metal roofs leads to some mistaken perceptions such as the belief that standing seam roofs are the best metal roofs in existence. But that simply is not true. Every kind of roofing system has some drawbacks and limitations.

How To Compare Metal Roofing Systems?

There are many different kinds of metal roofing systems. Each has unique advantages and drawbacks. Many are better alternatives than standing seam roofs. And to compare them against each other in order to make an informed decision, you’ll have to consider issues like system design, quality of the roofing material, installation ease and cost of the roof. Generally, the easier a roof is to install, the cheaper it will be.

Steel and Aluminum Shingles

Interlocking metal shingles have locks on all sides that hold the shingles in place. They prevent water or ice from seeping through, and the roofing contractor will install them using nails or clips to hold the shingles tightly to the deck. This form is versatile and can adjust to any kind of roof. Steel and aluminum shingles can be fitted onto valleys, sides and end walls, while fitting them around skylights and chimneys is easy too.

Standing Seam Roofing

There are benefits and drawbacks to using standing seam metal roofing. The biggest advantage is that they are extremely durable and will stay for decades. The level of protection afforded to your home is great, and these roofs can tolerate extremes of weather and temperature. The more sturdy forms that allow walking on them are slightly costlier.

The downside to standing seam metal roofs is that the cost escalates for more complicated installations and for steep roofs. Moving around while installing these roofs is difficult and dangerous. Special kinds of ladders and equipment is required for installing these roofs.

The design of standing seam roofs is also flawed. Ribs on the panels make them even harder to install. With specific kinds of roofs such as ones needing flashing, this can become an intricate and complex procedure, which naturally increases the cost involved. That’s why, even if standing seam roofs are a good choice for ‘simple’ roofing projects, they can be a nightmare for more complex roofing needs.

Corrugated Steel Roofing

Metal roofing systems that are based on corrugated steel are another option. Fasteners are exposed, and the material is cheap (usually 29 GA) and can be painted using acrylic colors. They rust easily and have limited durability and also are more prone to leaks. This makes them unsuitable as metal roofing systems of choice, especially when compared to more efficient systems like standing seam and metal shingle roofing.

In the final analysis, even if standing seam roofs look very attractive and aesthetically appealing, your best choice for a metal roofing system will be the interlocking metal shingles made of steel or aluminum. They will give you the same level of protection and durability at less than one-half the price of a standing seam metal roof. Your roofing contractor will also be happier at installing the simpler metal roofing system.
