There are several types of commercial roofing materials available on the market.  Choosing the right type of commercial roofing material will depend upon your location, energy efficiency, durability, cost, as well as, cosmetic appeal.  Common commercial roofing materials include sheet metal, asphalt, tile, and slate. 

Sheet metal can be used on commercial roofing and offers the buyer a very cost effective long-term choice.  Materials for sheet metal commercial roofing may include steel, aluminum, and even copper.  Metal roofing generally lasts longer than other tiles, depending upon location; a good metal roof can last from 30 to 50 years.  As well, metal roofing is less expensive than slate or tile roofing, and in most instances can withstand bad weather.  If you would like a roof that could possible last a lifetime and more, copper is a great choice. 
This metal is durable and although more costly has a life expectancy of 100 years.

Asphalt shingles are perhaps the most less expensive to purchase, however, their life expectancy is generally shorter than most other roofing materials.  In general, an asphalt roof can last only 20 to 30 years.  As well, many times they are easily obstructed by weather.  Therefore, if you live in an area where weather is a consideration; you may want to keep searching.

Tile is a beautiful choice for commercial roofing.  Tile roofing is available in clay, rubber, and even concrete.  Although, clay is more astatically pleasing and costs more than other tile roofing materials; it offers no more durability than other tile choices; generally speaking, you can expect a tile roof to last approximately 50 years.  Most tile roofs are very heavy and when considering this type of commercial roofing material, be sure to check with your architect to see if any special building reinforcements are needed. 

Slate shingles are by far the most expensive choice when it comes to commercial roofing materials.  In general, they do offer the business owner a long lasting durability and as well, they are very energy efficient.  And in the long run, they can save you money on electric bills; but don’t be surprised to pay 400% more upfront for materials and installation.  Slate shingles offer a lifetime of coverage, some manufacturers say even 100 years if applied correctly.
