Disclaimer: Obviously A.B. Martin believes in the benefits of using metal roofing, or we wouldn’t be manufacturing it. But we do sell asphalt shingles too. These articles attempt to make a fair comparison between asphalt shingles and metal roofing. If you decide asphalt shingles are better for your needs, we stock Tamko’s 30-year Heritage Shingles that have the best warranty on the market.


Should I worry about my metal roof being heavier than shingles?

When you think of putting steel panels on your roof, you’re smart to consider the weight.  Metal is one of the heaviest substances known to man, right?  The last thing you want to do is overload your trusses or rafters and bring your shiny new metal roof crashing down into your living room.

But before you start imagining dollar signs as you consider the expense of reinforcing your roof supports to prevent a tragedy, we need to ask a question.

Does a metal roof actually weigh more than asphalt shingles?

Many roofers will even install a metal roof over top of the old shingles to save you hundreds or even thousands of dollars in removal and disposal costs.  (Be sure to check your local building codes for possible limitations on the number of roofing layers permitted in your area.)

That’s just one of the ways you can save with a metal roof.

 

And considering that our metal panels come with 40-year paint warranties (with many metal roofs lasting over 100-years with proper maintenance), the savings over time makes metal a smarter choice.
