Metal Roofing and the Environment

 Metal Roofing and the Environment

Do the Right Thing!


The bottom line is that everyone cares about the environment. The choice of whether to choose a product that’s good for the environment or not so good for the environment  has become a big factor in roof choice decisions.

Metal, the Environment and our Mother Earth.

Metal has a natural ability to hold up against Mother Nature's elements while other building materials can be affected to the degree that eventually they will fail. Metal is far more durable through hot/cold temperatures, wet/dry weather cycles, high UV rays, windstorms, hail, ice and snow.

The composition of metal has recycled elements in the raw material. But Metal also has a much larger effect on the environment, on many levels, giving it a stronger position in sustainable building.

Metal Roofing Reduces Waste

When an insurance company pays for a damaged asphalt roof it always includes a tear-off of the old roof. Where do you think that roof goes? Yes, landfills!

Stone coated metal roofing is lightweight, allowing it in many cases to be installed over existing roofs. This minimizes the need to tear off and dispose of existing materials, which can save you money and has ecological savings.

Installing metal roofing over existing shingles provides an extra layer of insulation and acts as an additional sound barrier.

The life span of metal roofing is 50 + years, reducing the need to replace it. If it does ever need to be replaced, the tear-off material can be fully recycled.

Recycled Content

Most metal roofs have recycled content ranging from 25% to 95%. Conventional roof shingles have a dramatically shorter life-cycle and use oil-based products as their primary raw material.  This means they need to be replaced more often, which means more waste in the landfills, as they can't be recycled.


All of the Stone Coated metal roofing products installed by Midwest Lifetime Roof Systems are 100% recyclable.


Stone Coated metal roofing weighs a fraction of other roofing products such as asphalt shingle, slate and concrete tile. The average weight for asphalt is a minimum of 2-3 lbs per square foot, slate is 6 lbs per square foot, and concrete tile is 9 lbs per square foot. Stone Coated Metal Roofing products are only 1.4 lbs per square foot. The less weight on the roof plane, the less structural support is required in the building. This means less lumber or other materials is required in construction.

Clean Water Runs off

Metal roofing does not support mildew or algae, and is not produced with petroleum by-products. It does not contribute to the contamination of rainwater; therefore it is one less concern for well and ground water contamination. 

Interior Fungus

Metal roofing is a hydrokinetic material which allows water and snow loads to shed from the roof plane. It is also a hydrostatic material, a water barrier, which protects a roof system from growing fungus created by moisture. This fungus does live on other roofing materials.  This fungus contaminates ground water.

Algae Growth

Black algae streaks, seen everywhere now, absorb the sun's energy and increases the temperature in your home's attic. This results in increased energy costs to cool a home and premature failure of the roofing material, leading again to replacement and more waste in the landfills.

Energy Efficiency

One of the best benefits of Stone Coated Metal Roofing is that it reflects up to 70% of the sun's energy, thus minimizing heat retention. This results in less heat being transferred into your home's attic. Metal roofing can sustain up to 45% less heat gain than asphalt shingles. 

A stone coated metal roof reduces the "Heat Island Effect" which is a phenomenon in which cities can be two to eight degrees warmer than the surrounding countryside.

This effect can cook the smog that it indirectly creates, seriously damaging the atmosphere in and around urban areas.

Bottom line, Stone Coated Metal Roofing is one the most environmentally friendly products on the market!
