There are several types of roofing to select for your commercial building. Selection of course may depend on cost, the slope of your roof, and the weather conditions in your area.
1. Asphalt Shingles
These are the most common type of shingles used on home and commercial buildings today. Reinforced with organic material, wood fibers or fiber glass, these shingles can last from 20 to 30 years. Laminated shingles are also made of asphalt but come in a variety of colors and textures that give this shingle the appearance of more expensive shake or slate tiles. These more popular shingles can last between 25 and 50 years.
2. Metal Roofing
Steel, Aluminum, Standing Seam, Metal Tie, and Copper are just a few of the metal roofing materials used today as commercial roofing. If installed correctly, metal roofing may last between 30 to 50 years, which is just as well as the more expensive asphalt shingles. Metal roofing is not as costly as slate or tile roofing. In the past colored aluminum roofing has been known to fade, oxidize and peel, but many manufacturers have found the solution to this problem. This type of roofing can withstand most extreme weather but has been known to dent when hit with hail. Now a new granulated coating is offered to prevent this outcome. Copper is another option, though more expensive than aluminum. With a copper roof you can expect it to last up to 100 years.
3. Wood Shakes
Most roof shakes are made of treated pine, spruce or more commonly, cedar. Hand split shakes off that rough and thick look many seek. Most wood shingles are actually cut using a machine. This gives it a smooth finish, making it easier to install. Cedar is the first choice in wood shakes, offering up to a 30 year life. When shakes are first installed, they appear brown or red in color but expect the weather to fade the real wood and leave it a soft gray. Installation for wood shingles can run as much as 50% higher than other types of roofing.
4. Slate Shingles
Slate shingles are heavy and harder to install. Though they are easily breakable, they can add beauty to any home. This roof can last from 45 to 70 years and some claim it will last over 100 years if installed properly. These colorful and rich shingles will add a high price to your structure, costing as much as 400% more than other materials.
5. Tile Roofing
Tile is often made from clay but can also be made of concrete or even rubber. There is a large variety of colors and styles of tile roofing available today. Clay is more expensive than concrete tiles but the basic performance, durability and look of the tiles is the same. Lasting more than 50 years, this type of tile is often very heavy and your roof may need extra support.
Whether you have a new structure to roof or are re-roofing your commercial building, be sure to select the roofing company that can do the best job for you. Selecting a company that has completed roofs for commercial structures before will be your best bet. Ask if you can view a job they have completed recently. Be sure to ask about your specific needs, such as a flat roof often found on commercial buildings, heating, air vents and other roof obstructions. Also ask to see their roof installation license.
