Aluminum Metal Roofs vs. Asphalt Shingles
February 3, 2017 | By Mike Gonet | Filed under: Articles, Education, Green News, Metal Roofing
There are many pages and blog posts on this Classic Metal Roofs website that contrast the merits of aluminum metal roofs versus asphalt shingle roofs – to the advantage of the former, of course. We do not claim to be unbiased on this matter! Below we lay out the pros and cons of each in succinct table display form, for those who just like to cut to the bottom line, or for those of you who are just starting to educate themselves on the subject.
METAL ROOFS vs. ASPHALT SHINGLES | |
ALUMINUM METAL ROOF | ASPHALT SHINGLES |
ENVIRONMENTALLY COMPATIBLE | |
MAINTENANCE | |
Aluminum roofs when properly installed need no maintenance service. It is a good idea to inspect the roof to make sure that no damage has occurred from falling or blown debris after a significant storm. This is common sense and should be done regardless of your roofing material. | Asphalt shingle roofs need to be inspected on a regular basis. Damage can occur on several fronts. It is best to stay ahead of problems in order to minimize the cost of repairs. |
HEATING & COOLING FEATURES | |
DURABILITY | |
Aluminum roofs are made to last. Hurricane-rated wind, ice, snow, hail, and sunshine will not affect a properly installed aluminum metal roof. | Asphalt shingle roofs are effectively manufactured to fail. “Planned obsolescence” is the key concept here. Usually, failures are in high wind, and when ice dams form and water infiltrates the home due to the inherently flawed design. Sun causes asphalt shingles to break down and cup. Hail is the number one destroyer of asphalt shingles in the United States. |
STRESS ON ROOF STRUCTURE / WEIGHT | |
STYLE / DESIGN / STYLES / COLORS | |
Aluminum metal roofs are available in multiple shingle styles including a traditional shingle, a slate, a shake, and a Mediterranean barrel tile design. Standing seam in several widths is also a very popular choice among architects, homeowners, and builders. All are available in many colors and finishes. | The product is available in very limited styles. And colors? Black, brown, gray, and a few shades of each. Not much choice here. |
LONGEVITY | |
BLACK STREAKS, BUG INFESTATIONS, SQUIRRELS | |
Black streaks are a type of algae that live off the minerals in some types of asphalt shingles. Algae thrive in moist conditions, so it is most commonly found on shaded or north-facing roof slopes that do not get a lot of direct sunlight. There is no place for the algae to get a foothold on the aluminum to cause black streaks. Bug infestation is also a non-issue, as there is no place for the bugs to go because the roofs are interlocked together. And, it is impossible for squirrels to chew through a metal roof to gain access. | Black streaks are everywhere on asphalt shingles. It is true that algae do not damage roofing, but it certainly looks bad. It attaches to the granules and indentation of the shingle roof. Asphalt shingles overlap each other on the roof, which holds moisture and attracts bugs. Squirrels love asphalt roofs; they can chew right through them and gain access to the house interior.

PRICE / COST | |
RETURN ON INVESTMENT | |
Aluminum metal roofing is one of the best home improvement investments you can make to enhance the value of your home. Recent statistics here in New England assert that you can expect to recover 85% or more of your investment when the house is sold. Of course, then there are all the other benefits you reap every year that your house has an aluminum metal roof. | No return on investment, just depreciation of investment. This type of roof is considered a liability and is often a point of negotiation for lowering the offering price at the time the house is resold. |
