How to install Metal Roofing

How to install metal roofing
There are many steps involved to installing a metal roof. To give you an idea of what is involved, we’ve complied a list of tips starting with the very first panel.

To begin with, just like a home should be built on a firm foundation, you want your new metal roof to be installed to a structurally sound roofing system. You will want to replace any damaged or rotten wood, address any wood rot and water damage, and be sure that all of the rafters are undamaged and ready to accept the fasteners for your new metal roof.

If you have an existing shingle roof, it may be possible to install your new metal roof over the existing roof; be sure to refer to your local building code.
More on how to install metal roofing:

  • Make sure the first panel is installed square because the other panels will follow it and if it is not is square, the rest won’t be either.
  • On exposed fastener panels: While you are not required to, consider pre-drilling holes for your screws. Pre-drilling panels will make it easier to get the screw lines straighter. We’ve found that you can pre-drill about 10 panels at a time without too much trouble. Make sure to measure twice, drill once!
  • We found that using blue chalk, if you pop lines for your screws, will usually wash off with rain the next day as compared to other colors like red chalk which can be very difficult to remove.
  • When you begin to fasten the panels, be sure to screw your fasteners in straight. Be sure to not over-tighten the fasteners as this may cause gasket failure and potential water damage over time.
  • Consider your safety while installing and be sure to wear protective rubber coated gloves while working with metal roofing and flashings. This not only protects you from the sharp metal edges, it also gives you a better grip on the metal roofing.
  • Lastly, when it comes to how to install metal roofing, after you finish installing the metal roofing, make sure to brush off any metal filings / shavings that are on the roof. Otherwise they will cause unsightly rust spots where they rest on the metal roofing.

We hope this helps as you consider the task of either installing a new metal roof yourself or having a qualified metal roofing contractor assist you. Either way, we’re sure you’ll be pleased with your new metal roof.
