- Longevity. It will serve 50 years minimum, and if you opt for zinc or copper, its longevity may double.
- Low expenses in prospect (to be discussed in detail in the next passage).
- Lightweight. It’s easy to transport and install, and it poses no threat to the structure of the house.
- Low maintenance. Just be ready to remove the debris every 6 months.
- Fire resistance. It’s a Class A fire-rated and nonflammable.
- Weather resistance. It holds up easily to rainfall, snowfall, winds, extreme temperatures.
- Eco-friendliness. The roofing and its polypropylene underlayment are recyclable.
- Energy efficiency. You can easily install solar panels or similar energy-saving devices on your metal roof. Or you can buy cool roofing that will retain heat in cooler temperatures and release it when it becomes warmer.
- Diversity of looks and a rich palette. You can easily choose a desirable size, shape, and coloring.
- Higher one-time costs if compared to asphalt.
- Labor-intensive installation and a restrictive choice of experienced contractors. This Norristown roofing contractor is qualified enough to work with metal.
- Oil canning, which creates considerable waviness in the flat areas.
- Noise risks. If faults were made during installation, metal might be noisy.
- Community concerns. Certain Home Owners Associations won’t allow you to purchase metal roofing since its looks don’t fit into the surrounding area.
Metal roofing normally costs 20% less than the asphalt. But to install it you’ll need to buy screws, flashing, and ridge caps, or, better, ask for professional help. But even though you’ll pay these additional expenses, some metal roofs come with a 40-year warranty and require no maintenance. This said metal roofing should be regarded as a far-sighted investment.
Also, if your aim is to economize as much as possible, you can do retrofitting — that is, installing a new roof over the existing one. One more argument in favor of metal roofing is that it might be eligible for tax credits and insurance discounts.
- Low one-time expenses.
- Easy installation. Shingles are normally prepackaged and you need just to nail them to the deck.
- Affordable repairs. Shingles are easy to fix, remove, and replace.
- Availability and wide warranty coverage.
- You will quickly find a skilled installer.
- Short lifecycle (hardly longer than 25 years) and higher long-term expenses.
- Heavyweight, which might be stressful over time to the structure of your home.
- Intrusive installation. Asphalt shingles may compromise the structure of the building because you need to create holes in the roof to install them. You can’t resort to retrofitting and need to remove the old roof before installing a new asphalt one.
- Fire concerns. Even though the shingles are Class A fire-rated, they are partially composed of flammable asphalt.
- Damage risk. Asphalt shingles lift and rip off easily. They are not as weather-resistant as metal. Mold, mildew, algae can grow on an asphalt roof, and granules can flake off the coating over time.
- Limited palette. Asphalt shingles usually come in dark colors.
- Poor energy efficiency. A dark roof quickly absorbs the summer heat, so there will be an additional workload to the air conditioners.
- Low recyclability. Asphalt is recyclable, but very few contractors are aware of it.
The average price range for an asphalt shingles roof is from $2,100 to $4,800. The average price range for its metal counterpart is from $7,500 to $15,000. Thanks to its more attractive price asphalt shingles turn out to be a more common option among homeowners.
Asphalt shingles and metal roofing belong to approximately the same price range. Shingles may be more affordable as a one-time expense, but their lifecycle is twice as short if compared to metal. You should choose asphalt if you have no plans to stay in your house for longer than 25 years or if you will be ready to reinstall the roofing after that time.
You’d better opt for metal if the following characteristics are relevant for you:
A metal roof will serve you up to 50 years. Unlike asphalt, it comes in a wide color palette. But you’ll need to coordinate it in advance with your community if a metal roof is acceptable in your area.
