The efficiency of roof material is measured in terms of longevity, energy efficiency, appearance, durability, and maintenance. Metal roofs are an attractive choice due to their minimal maintenance, longevity, and energy efficiency. However, there are many factors to consider, such as cost and performance, before making a purchase decision. The following are the pros and cons of a metal roof.

 

Advantages

 

Longevity

 

When properly installed, a metal roof has a lifespan of 40-70 years, depending on the type of material used. These roofs are made to seal out water, withstand high wind, and offer resistance against insects, mildew, and rot.

 

Warranties vary from one company to another, although many roofing companies guarantee metal roof materials for 20 to 50 years.

 

Fire resistant

 

Metal roof materials have a class A fire rating due to their non-combustible properties. These roofs do not ignite or catch fires caused by wildfires or lightning sparks. In most cases, metal roofs are applied over a combustible material, such as wood shingles, since they have a lower class C fire rating.

 

Low Cost of Maintenance

 

Unlike other roofing materials, metal roof materials do not require costly periodic maintenance. Besides, they are easy to clean since homeowners can conduct periodic cleaning through hosepipe water cleaning.

 

Energy Efficiency

 

Metal roofs reflect heat from the sun, saving energy costs needed for air conditioning during the day. Although metal roofs have a lower R-value, they can be applied over rigid-foam insulation with a higher R-value.

 

Environmental Friendly

 

Metal roof materials are eco-friendly since they are mostly made from recycled material, and they are 100% recyclable at the end of their life.

 

Customizable

 

Metal roof materials can enhance a home’s aesthetic due to their uniqueness with different colors to choose from.

 

Disadvantages

 

Affordability

 

Metal roofs can be twice as expensive as other roofing materials due to their long-term durability and minimal maintenance costs.

 

Noise

 

Metal roofs have low noise insulation properties, especially during heavy rain or hailstorm. Homeowners are forced to add more insulation layers, which may increase the installation costs.

 

Performance

 

When poor installation is done, water may accumulate anywhere on the roof, causing severe damages. Moreover, it may dent easily during hailstorms or installation.
