Asphalt Shingles VS Metal Roofing

Asphalt VS Metal Roofing Choices

As you can imagine, we get a lot of Texas homeowners that would like to replace their older asphalt roofing shingles as replacement becomes a necessity. When folks just like you and I are considering a new roof, often a metal roof choice becomes an option to consider. Having said that, we have put together some ideas and considerations when choosing between a Asphalt or Metal Roof including the following considerations: Rust, Cost and the dreaded least favorite of all, complete loss or interference of your Cell Phone reception. This is something that most homeowners never will think about.

Cost of Asphalt VS. Metal Roofing

This is the biggest factor for most homeowners to consider between the two roofing choices. Let’s say the asphalt shingle roof replacement cost is $10,000 and the metal roof cost double (or more) at $20,000 +, this is most often the case that homeowners are often experiencing. Some will not mind paying the extra money that it takes to install a metal roof because that is what they have been desiring for some time.

The labor to install the two roofs is very different from one to another due to the skill level and experience in working with the two products. For instance, an asphalt roofing shingle is flexible and can be made to fit in many applications where as a metal roof panel is rigid and requires a much different set of skills and tools to fit in the same area of application. It is often common that roofers that have installed asphalt shingles in the past, will attempt to install a metal roof resulting many mistakes in installation resulting in an voided warranty. There is also a big difference in the cost of materials between the two products as well as the many options between the two roofing products as well.

This is where asphalt roofing shingles wins in my opinion. If a metal roof is going to cost you double or more, are you going to recoup this money in the long run? The short answer is yes and no and here is why: In the past, the asphalt roof will last anywhere from 12 – 25 years on average. That was in the past, today, GAF is offering a lifetime warranty on their asphalt composition roofing shingles replacement . This means, a longer replacement life if you install their lifetime asphalt roofing shingle warranty product.

Metal roofing products such as galvalume, offer a 25 year metal roofing warranty and other metal roofing products can range from 25 – 50 + years. We have even seen some lifetime warranties offered by metal roofing manufacturers as well. The reason for this range in warranty span, is RUST. These roofing panels are coated with paint or coated with a galvanized coating called, Galvalume. If they were aluminum or copper, they would never rust, however the cost would be 3 -5 times + the cost of an asphalt roof that can offer a lifetime warranty.

Having said all of that, here is some quick math thoughts for comparisons:

Should I go with a Lifetime Asphalt Roof @ $10,000 vs. a 25 – 50 Year Metal Roof @ $20,000 +? A quick math comparison quickly reveals that an Asphalt roof at half or less of the price offers the longer warranty of a metal roof, what are your thoughts? Form a cost effective perspective, the asphalt roof is less expensive in the long run if you go with the Lifetime Warranty that GAF is offering.

Rusting VS. Weathering Longevity Issues

This is where metal roofing wins big time in my opinion. When an asphalt roofing shingle gets weathered and old, it will experience granule loss and lose its structural integrity and start to fail and come apart.

Those ceramic granules are adhered to the shingle with asphalt petroleum based adhesive. As these shingles age they lose this protective coating leaving the underlying asphalt and fiberglass base to crack and become quite brittle.

No matter what one might put on top of this asphalt shingle, the base has become so deteriorated that it can no longer support anything that is coated on the surface of it. This is why roofing contractors  will re-coating metal roof over asphalt shingles.

On the other hand is the metal roof. When it starts to age the most common issue is loss of the painted or coated surface such as galvalume or Kynar 500 paint coating. When these factory applied coatings start to fade, they leave and expose the metal surface underneath to the elements. The most common response to this exposure of most metal products is surface rust.

This metal roofing panel often still holds its structural integrity and only exhibits unsightly surface rust as long as it has not been exposed for a lengthy span of time.

With this metal roofing panel still intact with only surface rust, it is the perfect candidate to be sprayed with a new fluid applied metal roof coating. This coating is completed sprayed on and has a warranty for 10 -25 years. So another words, for a “fee” you can extend the life of your roof for 10 – 25 years. Please note that I said… “for a fee”.

The Myth Of The Forever Metal Roof

When I get a call from a Texas homeowner seeking a price on a metal roof, there seems an instant connection that by installing a metal roof that it will be the last they will ever install. This is clearly not the case as the manufacturer warranties range anywhere from 25 years to lifetime. Even with a lifetime warranty from the manufacturer, you will eventually have to replace that roof after your warranty is claimed with the manufacturer due to the coating failure.

The metal roofing manufacturer typically will prorate the warranty claim that you have against them and either offer a small portion of the original price back to you or offer a discount on the replacement materials. The metal roofing manufacturer will not offer any labor money to replace the rusting and or falling metal roofing panels.

The same goes for asphalt roofing shingles should you ever need to file a warranty claim against them as well. After you have contacted them, they will come out and assess (look at) your asphalt roofing shingles and take an assessment on the service life that is left. The asphalt roofing manufacturer will make a settlement offer that is either a partial credit (rebate) towards new replacement roof shingles, or a possible cash value settlement. Either way with metal or asphalt roofing, you are going to be out of pocket some time down the road when either the warranty period ends or a claim needs to be filled due to failure.

Cell Phone Reception Interference

This is an area where most Texas completely forget to consider and is one of the most frustrating to find out onee the new metal roof is installed. Oh my and no fun.

Something to think about, when you have a metal roof installed on your home, you now have installed a shield that stops some of your cell phone signal from coming into your home. What you have now created is what is called the Faraday cage effect.

One of the ways around this is to install a signal booster that has an outside antenna to receive better reception. Sometimes this works and sometimes this will not depending on your existing reception situation. If your signal is already poor or marginal, you will probably have none with an addition of a metal roof replacing your non interfering asphalt roof.

  • Installation cost

Final Thoughts on Asphalt VS Metal Roofing

You have to choose between which roof is better for your home when you consider the cos, rust and possible cell phone reception issues associated with a metal roof. If you are liking that standing seam ribbed metal roofing look, then by all means go with that type of roof. Keep in mind that you are going to pay 2-3+ times more without really getting much longer of a warranty out of a metal roof. Should you decide on the Asphalt roofing shingle, you be saving money up front and in the long run if you get the lifetime warranty shingle that is offered by GAF.

Well done!

    Help me understand the difference between 1.Stone Coated Metal Roofing Shingles, 2.asphalt roofing shingles, and 3. Metal Roof. Thank you.

    • Greg Kapitan says:

      Gary,

      Thanks for these great questions. 1 the Stone coated metal roofing is metal based roofing shingle that is covered with the same 3M ceramic granules that asphalt shingles use that have a 2 flexible fiberglass base. 3 the metal roofing has no coating other than a painted surface and a metal base. I hope that answers your questions. Greg

  12. Tamra Jones says:

    I’ve been surfing online more than three hours today, yet I never found any interesting article like yours when it comes to roofing situations for shoppers. It’s pretty worth enough for me. Personally, if all site owners and bloggers made good content as you did, the net will be much more useful than ever before! Cheers!!

  14. Danny L James says:

    Hey you guys, as a newbie on the web, I am always exploring online for articles that can benefit me. Thank you for the website article of the differance between asphalt and metal roofing products. You forgot to mention that asphalt is the same as composition roofing. I learned this when installing shingles roofing back in the day in Ohio and then when I moved to Texas many years ago. Anyhow, I am not trying to sound bossy or anything like that, just wanted to put that out there.. That is, asphalt and composition roofing shingles are one in the same thing! OK, have a nice day.

    • Greg Kapitan says:

      Danny,

      The two roofing shingles are the same on the surface. However the asphalt has an organic substance in the middle. This product is very similar to tarpaper. The composition can have a fibreglass matt in the middle. They look the same on the outside for the most part. Sometimes the asphalt shingles are thicker becuase of the thickness of the product in the middle. That is mostly true here that your comment you said that, “asphalt and composition roofing shingles are one in the same thing” It is interesting that you have noticed this. Most homeowners do not know the differance that we have spelled out here. Thank you for your valuable input.

  15. Jodi Crudgington says:

    I’m getting a new roof and am considering Class 4 shingles vs a metal roof. Were you referring to Class 4 in your article?

    • texashomeexteriors says:

      Jodi,

      To answer your question, no I was not comparing to class 4 impact roofing shingles. “Class 4, UL’s toughest impact test (shingles show no evidence of cracks or ruptures on front or back of shingle immediately after impact). Compare to “standard” shingles, which may have ruptures or cracks visible on the front or back of the shingle immediately after large hail impact”

  16. Bill Jackson says:

    I enjoy the efforts you have put in this asphalt vs metal roofing article. Often it is hard to find clear information on home improvement comparisons. I also like the photos that you have posted to prove the point!! Bill Jackson.

    • texashomeexteriors says:

      Bill,

      Hey sir, thank you for your comments! Most Texas homeowners think that metal roofing is the end all to all of their roofing problems. That often is not the case and we believe that homeowners should be informed. That is why we posted this blog post for all to see.

    Hi Texas Home Exteriors!

    My name is Mike also known as MPS. For some time I have been considering installing a metal roof. One assumes that a metal roof is an end all to any roofing problems. Now sir that I have thoroughly read your article, I can honestly say that their is a difference between the two roofing products. This was brought up many things to my mind that I have not thought of. I am now reconsidering my options.

    Thank you for sharing this valuable piece of information.

    • texashomeexteriors says:

      Mike,

      Wow! Thank you for your response to our home improvement blog. I feel strongly that homeowners need to look at their options before making a decision to install a metal roof on their home. This is a big expense and should be thought out completely.

  18. Roof Repair Fort Lauderdale says:

    I must appreciate your efforts you put on this article. It’s really a very useful article because most homeowners get confused at the time of choosing the best roof for them. Metal roofing is good as compare to asphalt roofing as it remains long lasting in the south.

  19. Sophia James says:

    Excellent roofing post and beautiful comparison. Both option are valid at a place but when you need to repair the roof you need Roof Repair it is excellent for both.
