A metal roof can last anywhere from 15 to over 100 years, with an average of 50 years, depending on the material, installation, and environment. The specific metal is a key factor: aluminum roofs may last 20 to 45 years, while steel can last 30 to 60 years. Tin can last for up to 75 years, and more durable options like zinc, stainless steel, and copper can last from 80 to over 100 years. Factors that can shorten a metal roof's lifespan include living in a coastal region with corrosive salt air, improper installation (such as laying over old shingles), and failing to inspect and replace fasteners, which may wear out before the panels.

Hip roofs tend to cost a bit more than other common styles of roofs. Because of the complex labor needs required to build a hip roof properly, you can expect to spend more on labor if you choose to go with a hip roof over a less complicated roof style.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

Chimney caps have a solid top but perforated sides so smoke can exit safely. If rain or snow falls downward, chimney caps can protect the chimney’s interior. Just note that if rain or snow blows in sideways, there’s a higher likelihood it will enter the chimney—but it's not often a cause for concern as long as you have a cap.
