Considerations When Choosing a Metal Roofing System
Commercial Metal Roofing Systems
Roofing systems can become much more durable when they are drafted with metal. And when they’re not only properly installed along but manufactured as well, they go on to last for quite a long time and they also produce a better overall roofing quality when compared to other systems used. However, they can of course be somewhat more expensive than other systems and often range from $12 to $5 for every square foot. So, if you’re looking at the bigger picture of longevity, then any owner should close their eyes and dive into a metal system that provides a solid 30 or even 40 years!
When it comes to making decisions, buyers and contractors are faced with a couple tough choices. First, the biggest factor to be considered is the harsh weather conditions along with structural integrity as well as other building code restrictions. And they will also need to choose the type of metal to be used. Roofing steel comes in either zinc, copper or aluminum and are the most common when it comes to commercial roofing materials.
Additionally, in an effort to combat the elements the steel is usually coated or galvanized for better protection and metals such as aluminum are either anodized or painted to increase their strength. If you’re interested in using copper, we have some pretty great news for you! Copper is known to have a pretty long lifespan and it adds some extra beauty to your building. Zinc on the other hand is wildly popular for its low gloss finish and its amazing resistance to corrosion.
And when it comes to the metal’s gauge or thickness, these are determined by the overall exposure as well as the cost being spent along with the strength of the building to support something on the heavy side or the lighter side. However, when it comes to selecting the proper gauge for your system, a professional contractor will advise you since gauges start from 3 and go all the way up to 30. In essence this just simply means that it can range from a cost of $120 to $350 for each square inch that your system requires when being installed.
A product that falls into the 26-gauge category weighs 0.9 to 1 pound for every square foot and if you’re looking at something in the 29 range, it can weigh between 0.65 to 0.60 pound for every square foot used. Simply put, the lower the gauge, the thicker your material and lower gauges are chosen because of their outstanding durability. However, due to the increased weight the installation process becomes a bit difficult and of course thicker materials mean that the metal will be harder to bend and work with.

When it comes to the connections and configurations, there are several available on the market. These being either vertical panels or sheets and even horizontal ones. Additionally, the option of a shingled choice is also available along with tiles. However, the initial connection between the panels used can be created with various profiles which go on to affect the systems overall durability as well as the need for future maintenance.
Some contractors prefer to use the vertical option since the panels can be either fastened together, they can also have a standing seam as well as a batten seam. Standing seams are formed with two adjacent panels are brought together in either a double or single fold that is done perpendicular to the plane. Fastened planes are mechanically attached via washers or fasteners. And Batten seams are created with the use of wooden strips at their joints which are then flashed with metal caps locking them into place.
When it comes to insulation as well as underlayment choices, some are either single ply at a slope of more than 18 degrees, two plies at a slope of less than 18 degrees, synthetic sheets, self-adhering membranes and asphalt saturated felt sheets. However, in some cases contractors use a slip sheet between the underlayment and the roof in order to prevent sticking due to high temperatures. And sometimes an insulation layer is used to prevent unwanted sounds and even excessive heat from coming in.
Insulation can also be installed over solid decks with the use of polystyrene panels, insulation boards and fiberglass insulations.
And last but not least, owners or even property managers should ensure that their contractors are following the building code requirements. Codes are typically used for thermal insulation values, vents, flashing details, the initial pitch of the roof, connection type and even load bearing requirements. As such, these should be properly looked into along with others by an industry professional.
