We all want our Metal Roofing and Cladding to exceed their expected life expectancy.
But how do we accomplish this? With Proper Installation.
Extend the Lifespan of Your Roof with the right fasteners and proper installation
Proper installation attributes to life expectancy, however, this may vary based on the project, roof type, and geographical location of the roof. Taking this into consideration, how do you ensure proper installation?
For this, we look at the one thing all roof installations have in common, specifically pierced fix roofs, and that is the use of a proper long-lasting fastener.
The life of your exposed fastener should match or exceed, the life expectancy of the metal roof itself. There are a variety of long-lasting roofing fasteners commonly known in South Africa as Class 3, Class 4, and Class 5 roofing fasteners.
Therefore, it is important to know your requirement for each roofing project to properly inform your client, contractor, or buyer.
The proper installation of each fastener is crucial as well. Roofing screws that are over-tightened or under-secured can lead to a bad seal, which ultimately leads to leaks and other complications.
To install Metal roofing or Cladding means you are making a reasonable-sized investment. So it’s normal for homeowners, clients, or roofing contractors to want to save money wherever they can.
In some instances, the homeowner, client, or roofing contractor may use an inferior fastener or opt for a Class of fastener one lower than what is required. Instead of Class 4 fasteners, they instead opt for Class 3 fasteners, instead of Class 5 fasteners, they choose the Class 4 fasteners.
In many cases, the inferior or incorrect Class of roofing screw will rust prematurely and need to be replaced. When rusted fasteners are not noticed in time, it will inevitably cause damage to the roof sheeting, and may lead to the metal roof sheeting having to be replaced, resulting in an unexpected expense.
Although long-lasting roofing screws can be more expensive initially, it truly saves you time and money in the long run.
Failure to use long-lasting fasteners can reduce the lifespan of your metal roof significantly. Class 1 or 2 non-long-lasting fasteners will rust sooner than anticipated.
If you are unsure which Class of fastener to use for your next roofing project, consult our Fastener Guide, or contact Corroshield SA to help you make the right choice to help extend the lifespan of your roof.
