Metal roofing vs. shingles

When you are in the market for a new roof, you will have to determine what kind of roof will be best for your home. Maybe you’ve narrowed the choice down between metal roofing and shingles? In that case you will want to look at their benefits and disadvantages.

While metal roofing usually costs more to install than shingles, one big advantage they have over shingles is longevity. With care, a metal roof can last 50 years or more before they need to be replaced. Most shingle roofs last on average about 20 years.

While shingle roofs may not last as long as metal roofs, they are easier to repair and the repairs usually cost less than repairs on metal roofs. At the same time, metal roofs tend to need fewer repairs and less overall maintenance. They are also highly fire and weather resistant as compared to shingle roofs. But there are also some municipalities and homeowner associations that don’t like the look of metal roofs, so you may not be able to place a metal roof on your home or will have to get permission to do so.

Another distinct advantage metal roofing has over shingles is its energy efficiency, especially modern metal roofing that is designed as cool roofing. Cool roofs release heat better in the summer and retain it better in the winter.

What color metal roof is the most energy efficient?

One major advantage metal roofing has over other roofing systems is energy efficiency. A metal roof’s energy efficiency is affected by the color you choose.  Overall, lighter colored metal roofs will be more efficient than darker colors, especially in warmer climates. Colors such as white, beige, bronze, sand or light blue will reflect the sun’s rays better than darker colors.

The list below will give you an idea of how metal roofing works for energy efficiency:

  • Metal roofs reflect sunlight away from the roof, keeping it cooler.
  • Coof metal roofs retain heat in the winter and release it hotter weather.
  • Metal roofs also protects backing insulation better than other materials.
  • Metal roofs also support high efficiency windows and skylights better than other systems.
  • Metal roofs allow for easy installation of solar panels.

Energy efficiency can be affected by several components of your home, especially if your AC is not cooling. An HVAC system that’s not working right will affect energy efficiency.

How much does a sheet of metal roofing cost?

What is the best metal roof system?

Metal roofing for houses has become popular in the last few years. What type of metal roof you choose will depend on your personal needs in roofing. Another thing to consider is location. If you’re in a coastal region or areas where salt content is high, aluminum roofs will be a great option because they are less susceptible to corrosion. Copper roofing can be very aesthetically pleasing but can be vulnerable to denting in areas where it hails frequently. Steel roofing is usually lower in price than other metals and is a flexible material. Advances in design allows for the steel to be designed to mimic other metals like copper or zinc. Because of its low cost and ready accessibility, steel roofs are becoming common in metal roofing for commercial and residential building.

Can you put a metal roof over shingles?

If local building codes allow it, you can install a metal roof over existing shingles, although installing it this way, if not careful, can cause water vapor to get trapped between the metal and the shingles. Moisture build up then creates opportunities for mold growth and rot.

What are the disadvantages of a metal roof?

One of the primary disadvantages of metal roofing is its high initial installation cost. Metal roofs are also prone to oil canning, which is the visible waviness in the flat areas of the roof. While it does not impact the effectiveness of the roof, it can affect the look of the roof, which in turn can affect overall curb appeal. Some insurance companies may charge higher premiums because the roof is worth more and a replacement would cost more. Additionally, some cities and HOAs may frown on metal roofing being installed in the neighborhood.

How metal roofing is made
