It's a good question - is a metal roof worth the extra money? The answer varies from one project to the next, but here are a few questions that can help you determine whether a metal roof is worth it. 
1. Are you planning on staying in your home for the foreseeable future?
If you answer "no" to this one, you can stop reading now - the cost of a metal roof isn't worth it. Beyond its inherent characteristics (eco-friendliness, performance, durability, choice of styles, colors, etc.), one of the most attractive features of a metal roof is its lifespan. Most metal roofs will last 50 years or longer - and that's part of what you pay for from the start. If you're not going to stay in your home for the long-term, save yourself the money and replace your roof with something temporary. By the time it requires replacement (and it will, if you're using something besides metal), it'll be someone else's problem!
2. Are factors like eco-friendliness, longevity, performance and aesthetics important to you?
This is an important consideration. If your goal is simply to get something up there that will keep the elements out, then again, a metal roof probably isn't worth the upgrade. But if you're house-proud and the quality of your roof matters, it's time to take a serious look at metal roofing. Nothing else can compare across the board in terms of green factor, energy-efficiency, longevity, good looks, safety and resilience.
3. Are you willing to consider a greater up-front investment for a material that likely won't require repairs or replacement for the remainder of the time you live in your home?
If price is your sole consideration, again, a metal roof is not worth it. You'll pay more for a metal roof than most other material options, and the pay-off is a great-looking, high-performing roof that likely won't require repairs or replacement for upward of 50 years. And, in fact, over a lifespan like that, a metal roof actually costs less than other roofing options that require replacement. Here's how it works:
Say a new metal roof will cost you roughly $30,000 for material and installation. That's a lot of money, particularly when you compare it to an asphalt composition roof that would cost around $10,000. BUT - and here's the kicker - that comp roof will require replacement in roughly 10-20 years. When you replace that roof (the labor cost of which roughly doubles every 15 years!), it's likely to cost more than $20,000. Now you've spent the same amount as you would have on the metal roof and in exchange you've had the pleasure of re-roofing twice and adding to the increasing burden on our landfills. Keep doubling the cost and tacking it onto the original price of that comp roof and you'll see that the "cheap" option doesn't seem like such a smart move after all!
If you've read through these questions and aswered "yes" to all three, do yourself a favor and get some prices for a new metal roof system. It's highly likely that a metal roof is definitely worth it in your case.
