Replacing Asphalt Shingles with a Metal Roof

Keeping tabs on home maintenance is one of the best ways to preserve its value. When you find a problem, keep in mind that– regardless of upfront expenses– addressing these issues before they degrade far enough to cause further damage will also end up being economical in the long run.

So if it looks like 2020 is the year to replace your deteriorating roof, the first question you should ask yourself is “Do I stay with the existing roofing material, or try a different option?” For example, despite its higher initial cost, metal roofing is likely to save you time and money over the years. Compared to asphalt shingles that typically last 15-18 years, metal roofing has a lifespan of 60 years or more and requires only minimal maintenance. A metal roof also reflects heat, making it more energy efficient than a traditional asphalt roof.

If you’re intrigued by the benefits of metal roofing over traditional asphalt shingles, there are a few things to keep in mind. When you get the quote, remember that you’re buying a higher-end, more durable product that requires a more complex installation. There are other factors that will play a role in determining the cost of your new metal roof including:

Location. A new metal roof with identical specs in an expensive market like Washington, DC or northern Virginia is likely to cost 30-50% higher than it would in the middle of the country.

What’s Your Square Footage? Contractors measure roofs in square. One square is equal to 100 square feet. Typically, the greater the square footage of your roof, the less you will pay per square foot. Surprisingly, very small orders (200 square feet or 2 squares of custom-sized sheet metal panels) can be very expensive.

Design type matters. Another significant (but fortunately more controllable) factor to determining metal roofing costs is the type you decide upon. The least costly metal roofing option, corrugated or ribbed steel, could run $6.00 to $8.00 per square foot installed, depending on the gauge of the metal and the type and quality of the paint finish required for your climate. A metal shingle roof could cost between $8.00 and $13.00 per square foot installed, while a standing seam metal roof may be $10.00 to $16.00 per square foot installed.

How complex is the installation? If you have a complex roof with chimneys that require flashing, many angles, dormers, sidewalls, and/or skylights, sidewalls, your installation will be higher.

What type of metal do you want?
Steel is a common and acceptable metal for roof fabrication. For most residences and buildings in the Frederick area, we recommend:
– G-90 Galvanized or “hot dip” steel with a zinc oxide coating and Kynar paint finish is the most affordable option. Interlocking steel shingles and tone-coated shingles and tiles are typically made from G-90 galvanized steel.
– Galvalume to fabricate residential, standing seam panels. Galvalume steel provides longer-lasting protection against rusting and corrosion than does galvanized.
Aluminum provides longer-lasting protection from corrosion, and is generally considered a more durable option than steel for use in coastal areas.
– Aluminum shingles start at around $9.00 per square foot including trim.
– Aluminum standing seam panels are fabricated and cut to order. Expect an initial base cost of around $12.00 per square foot.
Copper and Zinc are premium quality metals whose price depends on the weight and thickness of the shingles or standing seam pans. Installation is more complex and expensive, especially when dealing with 16-20 oz. copper standing seam panels, which require soldering.
