The Pros and Cons of a Metal Roof

If you are considering a metal roof for your home, it’s important to weigh the benefits vs drawbacks, especially in comparison to other roof types like asphalt, tile, slate, or wood.

First, it’s important to understand how a metal roof is constructed and installed in each home.

  1. Thin sheets of metal are measure and cut into panels
  2. It is seamed for custom installation over roof underlayment
  3. The metal can be formed to replicate tile, slate, asphalt shingles, or shakes.


Lightweight & Durable. Depending on the type, metal roofing is usually the most lightweight option. It can weigh as little as 50 to 150 pounds per square, compared to tile, which is about 750 pounds per square or concrete which is about 900 pounds per square.

Long Lifespan. If a metal roof is properly installed, it should last as long as the house. It is capable of surviving high winds, sealing out water, and easily shedding snow. Because of the way the panels interlock, metal roofing is less vulnerable to leakage or sealant problems. In addition, the hard and slippery surface makes the roof basically impervious to rain and snow!

Fire, Mildew, Insect and Rot resistant. Metal roof materials are noncombustible and won’t cause any mildew or rotting by leaking or trapping water in between shingles. In addition, insects don’t consider metal roofs as a comfortable home, so there won’t be any problems with an insect infestation with a metal roof.

Excellent Insulation. Especially for attics, metal roofs provide great insulation in comparison to other roof materials.


Expensive Purchase & Installation. The initial cost can often be steeper than other types of roofing. Why? This is because of the long-term durability and strength of the material. If you are planning to stay in your home for the long term, this is a great investment because you’ll ultimately save the difference by avoiding future roof replacements.

Noisy During Heavy Rain. Although some enjoy the sound of rain and romanticize rainy days, for others it can be more drum-like. During rainstorms or hailstorms, metal roofing is generally louder than other roofing materials. This can be avoided by using structural barriers and utilizing sound-deadening insulation though, so if your heart is set on a metal roof, rain won’t get in your way!

Surface Dents Visible. If an avocado or large pine cone falls on your car, you will presumably get a dent. Metal roofing is similar due to the easily dented and malleable structure of the material. During a hailstorm, or if large shrubbery falls onto the roof, it can be impacted permanently.


With all home improvements, there are pros and cons to think about before choosing the right option for your family’s sanctuary. If you have any more questions, contact Willamette Power Roofing and Roof Cleaning today!
