How to Install Metal Roofing in Six Easy Steps

Metal roofing is sturdy, energy-efficient, and looks beautiful. You can always install metal roofing to your house at a later stage too. You can hire a contractor to install the roof for you. If you have decided to install metal roofing by yourself, you will need to follow some simple steps.

Before you can install the metal roofing, you will need to measure the area of the roof and order materials for the job. It is also better to assemble all the tools you will need for the job beforehand and keep them organized nearby at the work site. You will need fasteners, staple gun, power shear, drill, roofing nails, self-sealing screws, jigsaw, and other tools. You will also need a sturdy ladder and a trash bag to collect the debris from the roof.

Here are the six steps to install metal roofing.

Step 1 – Remove Old Roofing Material and Repair the Frame

First, you will need to remove the old roof. It is possible to add corrugated metal over shingles. But it is better to start from scratch and remove every bit of old roofing materials before putting in new ones. Make sure to remove any nails sticking out of the frame. Reposition the gutters as well.

When the roofing structure is exposed after you have removed the existing materials, inspect it and repair any damage to the frame.

Step 2 – Add an Insulation Layer

Insulation stops moisture from seeping into the rest of the house via the roof. You can use a single layer of roofing felt for the purpose. You will need to secure it over the roofing frame using nails and a staple gun.

If the house you are working on is in a location with extreme weather conditions then you can add an additional layer of insulation. But make sure to stick the two layers together.

Step 3 – Add the Edging

Edging or the eave flashing refers to metal strips used to seal the roofing perimeter. It is an essential step to install it on the roofing frame to secure the roof. You will need nails measuring 1¼ to install it.

Step 4 – Affix the Metal Panels

Now, it is time to fix the metal panels. It is best to begin doing at the longest line between the edge and the peak of the roof.

Spread the roofing sheet from the peak to the eave. It should cover the edge also. Ensure that the sheet hangs by at least ¾ inch off the edge. You can extend it, even more, depending on the kind of overhang you want.

Use roofing screws at least 12 inches apart from one another to fix the entire roofing material. Overlap the sheets a bit to secure them properly. If you are using exposed fasteners then refrain from fastening them too tightly. Exposed fasteners contain rubber sealants that keep the screws safely in place. Tightening them excessively can break or displace the rubber seals.

If required, use a good quality sealant before spreading the sheets over the roofing frame. You can use 100% silicone or even adhesive silicone for the purpose.

Step 5 – Install the Flashing

To further strengthen the roof, you need to add flash to it. Flashings are metal pieces or trimmings used over the place where one metal sheet overlaps or meets another.

When you add the flashing, you can protect the house from rain, hail, and other weather elements. You will need one or two rows of screws to fix it depending on the size of the flashing.

If you need to use the flashing on the top of the roof, you can do so by bending it into a ‘V-shaped trim’. Trim the flashings if you need to before installing them.

Step 6 – Inspect the Work

The roofing work is not complete until you have inspected it for any omissions or errors. Check for loose fasteners or any part of the roof not covered properly. Remove all the tools from the roof including any spare screws. Stop the work only if you are fully satisfied with it.

Your new metal roof is ready for you to enjoy.
