Metal roofing shingles are a popular alternative to asphalt and other roofing shingles, providing a unique appearance for your home. Metal shingles are also available in different shapes and styles, so you should be able to find something that best suits your home. Unlike many other materials, metal shingles are particularly durable. They are especially practical in colder places, as snow and ice tends to slide off metal roofs rather than building up and causing damage. Installing metal roofing shingles are not any more complicated than installing shingles of different materials. However, it is a time-consuming and labor-intensive job.

Step 1 – Take Measurements

Before you order the number of shingles you need, you will first need to determine the area of your roof. To do this, measure the width and the height of the roof and multiply these two figures together. Purchase the necessary number of shingles from your hardware store. Make sure that you add an extra 10 to 20 percent just in case you underestimate the amount that you need. It is always a good idea to have some spares handy as well, in case you need to replace some at a later time.

Step 2 – Remove Any Old Shingles

Assuming you are replacing an old roof, remove the old shingles one by one. Be careful not to damage the existing roof beneath. If there is any damage to the roof beneath the shingles, it should be repaired now rather than later. To remove the existing shingles, use a pry bar to lift them up and pull the roofing nails out that hold them in place. Remove any existing roofing felt as well, as this will likely end up becoming damaged in the process.

Step 3 – Lay New Roofing Felt

Install a roll of roofing paper over the roof to thoroughly cover the surface. Start from the bottom and work your way towards the top of the roof. Be sure that any separate sections of the roofing felt overlap each other by about an inch. Staple the felt in place.

Step 4 – Install the Shingles

Metal shingles are installed from the top down rather than the other way round as with asphalt shingles. Install the first row of shingles at the top, along the entire length of the roof. Install the metal flashing and ridge cap on top of this. Use metal roofing screws to attach the shingles in place. For the second row, start with a half shingle and then work your way to the other side of the roof. Stagger each row that you install, making sure that the seams don’t line up. The second row and onwards should slide under the previous row and lock in place.

Finally, the edge of the roof will need to have drip edges and end caps on it. Install these after all of the metal roofing shingles have been installed.
