Pros and Cons of Metal Roofing: A Complete Online Resource

Pros and Cons of Metal Roofing


A complete guide for home-owners.



When it comes to weighing the pros and cons of metal roofing against traditional asphalt roofing, the comparison isn’t a difficult one, home owners find.

Investment grade roofing is commonly known to provide far more advantages than traditional asphalt roofing-- namely, increased energy efficiency, protection from the elements and even tax credits – thusly, there's a surplus of information online and readily available for consumers seeking out this information.

Fewer comparisons, however, are available for pro and con weighing home-owners, between the various types of metal shingles available within the residential metal roofing market.

For home-owners considering Investment Grade Roofing, we’ve put together this comprehensive comparison guide covering pros and cons of metal roofing, stacked up against asphalt shingles, and cross compared across the various metal roofing types.

Q/A on Perceived Possible Disadvantage of Metal Roofing



A recent question posted by a home-owner in our Ask-The-Experts forum deals with the topic of expansion and contraction.

Dan writes:

Looking at the advantages of installing a metal roof, I have come across information referring to expansion and contraction problems; that over time, with heat and cold, the panels expand and contract lossening the fasteners and causing leaks. Is this a concern?


Answer: This question is probably best raised with individual metal roofing manufacturers. There are various methods by which various products deal with expansion and contraction. There are lots and lots of metal roofing products available today which have no problems with expansion and contraction. Some of the methods for accomplishing this include clip fasteners (rather than fixed fasteners) and accordion-style folds in the metal …

Comparing Advantages of Different Metal Roofing Types



Steel Roofing - Advantages



Galvanized Steel(steel with a coating of zinc/aluminum)
& Galvalume Steel (steel with a coating of aluminum/zinc)

Extraordinary outdoor corrosion resistance and longevity

Broader range of application than other roofing materials

Broader range of price levels and products than many other kinds of metal roofing

Due to their strength and weight. Steel roofs have passed the UL 90 wind tests

Aluminum Roofs - Advantages



Light weight - Consumers can re-roof their home and reduce the weight on their housing structure

Does not require structural reinforcement

Resistance to rust and corrosion over time

Aluminum roofing shingles are completely recyclable and often have a high recycled content


Does More for the Environment.



Perhaps the most important of advantages a metal roof provides, is its positive impact on the environment.

The decision to purchase and install metal roofing can have a greater positive impact on the environment than even a lifetime of household recycling.

Homeowners may not be aware that the recycled content in metal roofing is extremely high, which conserves both natural resources and the energy needed to convert those resources into usable materials.

  1. I am considering a metal roof for my unheated pole barn to go over a leaky asphalt roof. Is this a good idea or should the old shingles come up first?

  2. You'll want to check with your installer; however, in many cases, a metal roof can be installed on top of an asphalt shingle roof. Of course, your contractor will also want to check for the integrity of the support system, and address any repairs needed to the underlying structure prior to installing the new roof.

  8. If you install a metal roof before December 31, 2010, you may be eligible for a Federal tax credit. You can receive a tax credit for 30% of the cost (up to $1500) for Energy Star metal roofs with pigmented coatings. Ask your roofer if your choice of roofing contains pigmented coatings. Pigmented coatings increase the energy efficiency of these roofs.

  11. Metal roofs are an excellent choice in roofing. Leaves and debris are washed off during rain storms. Check out Kynar baked enamel finish. They are the superior choice.

  13. Someone I know lives in Orange County (Newport Beach)and is planning on getting a new roof. They are thinking of going with this roofing company: hoytroofs.com. However, they don't do metal roofs, and I am wondering if you would recommend a metal roof more so than any other type of roof in the "beach environment". Is there any benefit to metal roofing over tile (for example) when it comes to the wear and tear of the ocean climates and weather conditions?

  14. Metal roofs perform very well in extreme weather conditions, and are very popular in beach environments. Check out the MRA site for a list of contractors who install metal in Newport Beach - I'm sure there are a few.

  22. My sister is about to redo the roofing on her new home, so it's nice to know what her options are. We hadn't even thought about considering metal roofing before.

  23. I totally agree with the comparisons above. Asphalt roofs are very affordable, but the cost of maintenance accumulated over time rises exponentially. Metal roofs, on the other hand, are very efficient and durable. If you want to find a balance between longevity and upfront costs, metal roofs are the best option for you.
