Metal Roofing

Aside from the preferences of the property owner, there are a number of factors that have to be considered before finally setting on a specific material to use on the roof. 

When putting everything together, there are actually many reasons why metal roofs are favored against others.

Reason #1: Water-Resistant

Metal does not allow water to easily go through. The only weak spots for metal roofs are the seams which can be heavily sealed and protected to prevent any water from passing through. This is one of the underlying reasons why metal roofs are a lot better for use on low slope or flat roofs. Because these types of roofs cannot rely on the pitch to pull water down and away, there is a likelihood of water pooling. The use of a water-resistant material, such as metal, is essential in this case.

Reason #2: Rigid

In line with the high likelihood of water pooling mentioned above, the rigid structure of a metal roofs works well to actually prevent this from even happening in the first place. 

Reason #3: Better Drainage

Even when there is no pitch to allow the roof to take advantage of the effects of gravity, metal roofs are still able to integrate a good drainage system. The water on metal roofs can easily flow down to the edge to enter into the rain gutters. 

Reason #4: Wind Resistant

Metal roof materials have been tested and are designed to resist high winds, 

Reason #5: Puncture Resistant 

One of the major advantages of having a flat roof is that it is easy to walk on top, making it more convenient for homeowners, contractors, and roofers to maintain the roof. However, this means that the roofing material has to be strong enough to not be damaged by people walking atop of it. Metal roofs are successful at being resistant to wear and are also able to withstand hail and other debris.

Reason #6: Cost-Effective

Metal roofing can save you tons of cash because of the lower overall labor cost because it takes much quicker to get installed. The materials are also significantly less expensive than the other options.

Reason #7: Durable

The design and material itself, which is further protected by multiple coats protective paints, is extremely durable. On average, you can expect a metal roof to last even up to 50 years.


There are also a few cons that should be noted in regard to metal roofing on a flat roof. One of the cons is that it is a clunky material that is both heavy and difficult to work with. While installation for this type of roof may be easy, the replacement can be quite tedious as the structure is meant for more permanent usage. When needing a replacement, you’ll often have to tear away the whole roof and get an entirely new structure.
