Is it time to replace your old roof?

Of all the roofing materials out there, metal is the best choice. There are several benefits of metal roofing, including durability, longevity, energy-efficiency, and safety. However, in order to make the most of these benefits, the roof must be installed properly.

In this article, we’ll tell you how to carry out a successful metal roof installation.

The Essentials of Metal Roof Installation

In order to install your roof properly, it’s important to pay close attention to four key areas.

1. Foundation

Metal roof installation must always begin with a good foundation. Before you install the metal shingles, you must first lay an initial sheeting underneath. This will prevent any damage, reducing the need for roofing repair in the future.

2. Alignment

Alignment is important to both the look and function of your roof. This means that the vertical lines of the roofing panels must run square to the eaves, which are the overhanging edges.


  • If the first panels aren’t squared up correctly, they’ll have a domino effect on the rest of the roof. All the other panels will be tilted, and in the end, the entire roof will be off.
  • Seams of panels should have a small space in between. This is needed to allow for the expansion and contraction that will occur as a result of changes in temperature.

3. Sealant

Sealant prevents moisture from getting in between the metal sheets of your roof. This not only prevents leakages, but also stops any unwanted critters from making a home inside your roof. The last thing you want is an infestation! On top of all that, it saves you money by providing insulation.


  • Sealant tape closes gaps between sheets when it’s applied under every layer and along the eaves. This stops air and water from seeping through. This is especially important during those cold Milwaukee winters, when snow starts to settle on your roof.
  • A topcoat sealant finish will then reflect heat, keeping your roof cool and your energy bills low.

4. Fasteners

It’s essential that you use the right fasteners during your metal roof installation. Otherwise, your roof won’t last as long as it should. Standard nails aren’t good enough. Instead, you should use screw fasteners, which have much more strength and holding power.


  • Pancake-head screws are ideal because they are flat, which means that the next panel can be laid flush on top of them.
  • Be sure to use the screws with metal and neoprene washers to get a good seal. When fastening, ensure that they penetrate at least one inch into the wood. The screws should be tight, but not too tight.
  • Over-tightening screws will result in broken seals, and the wood underneath could also split as a result. This will allow water to seep through cracks in your roof.

Leave It to the Professionals
