Are Metal Roofs More Expensive Than Asphalt?

Initial Costs

• Asphalt shingles are by far the least expensive roofing material. Even with the cost of professional installation, which includes shingles and supplies, it is still the most economical option. Because asphalt shingles are easy to install, homeowners can save even more money by doing their own roofing work. Metal roofing is always more expensive than asphalt. Its prices can also vary by the type of metal used. Aluminum can be cheaper than steel, and copper usually costs more than all other metals. Metal roofing is harder to install than asphalt, so homeowners will likely have to pay professional installers.

Long Term

• Metal roofing is a better long-term value. Commonly made of copper, aluminum and steel, metal roofs have a lifespan of 50 years or more. Asphalt roofing has a lifespan of 15 to 30 years, so homeowners will end up replacing it sooner than if their roof was metal. Because metal is low-maintenance, there will be fewer costs for repairs and upkeep of metal roofs. Metal also helps insulate homes and reflects heat, which means lower energy bills. Some insurance companies offer discounts for homeowners with metal roofing. Both metal and asphalt roofing may be eligible for tax credits from the Environmental Protection Agency’s Energy Star program.

Unexpected Expenses

• Other factors can increase the likelihood a homeowner will spend money on unexpected maintenance and repair. Improper ventilation can damage asphalt shingles, causing them to curl under. Asphalt shingles are also prone to algae growth, which leaves black stains on the roof and can eventually damage the shingles. Metal roofing, though quite durable, is so lightweight it can be dented when hit by tree limbs or other hard objects. It may also be dented when walked on.

Considerations

• In addition to short- and long-term costs, homeowners should consider which type of roof works best in their climate. Asphalt is acceptable in all climates, but works best in cooler areas. The sun’s UV rays can damage ceramic granules inside asphalt shingles, which results in cracks and color loss. Metal roofs work well in a variety of climates, and can be created to look like asphalt and other types of roofing material. Unfortunately, if it is damaged, it may be difficult finding an exact match in replacement pieces for a metal roof. Homeowners should get quotes from several roofers to get the best price on installation.
