Adding corrugated metal roofing to your home can give you many benefits over other kinds of roofing. The metal sheets that make up the roofing are relatively cheap. They are also very strong and are quite resilient in withstanding the forces of nature. Corrugated metal roofing also acts as a very effective insulation. Here is a step by step guide to installing corrugated roofing on your house, garage, or shed.

Step One: Measure Your Roof

The first step to installing a corrugated metal roof is determining exactly how many metal sheets you will need. First, measure the length of the ridge of the roof. Measure it in inches from the left to the right and write down this measurement. The average metal sheet for corrugated metal roofing has a width of forty four inches. Divide the length of the roof by this number to determine the number of rows of sheeting you will need.

Now, measure the width of the roofing in feet down each slope of the building. Similarly record this number, but this time divide it by six. This is the number of columns you will need. Multiply the number of columns by the number of rows to determine the total number of metal sheets you will need.

Lastly, you need to calculate the number of ridge caps you will need to purchase. Simply measure the edges of the roof of the structure in feet. Also measure the ridges between the slopes. Add these numbers and divide by six to determine the number of ridge caps you will need to purchase.

Step Two: Cover Your Roof with Felt

The next step is to cover your roof. Purchase some standard roofing felt from your local home improvement store. Staple it onto your roof by inserting a staple every three inches on the edges of your room and every six inches in the space past the edges. Let deferent pieces of the felt overlap by at least three inches.

Step Three: Nail in the Roofing

Start this step by taking one sheet of metal roofing and placing it on one of the corners of the roof. The sheet should hang over the edge by two inches. Now take a nail approved for use in nailing metal roofing. Place the tip of the nail in the middle of the metal ridge that curves away from the roof. Also place a washer in this same spot and the nail in between it. Nail it in. Now add more nails to this center part that curves away from the roof. Each sheet should use about twenty two nails. Do not add nails near the edges of the sheet.

Now take the second sheet of metal. Place it next to the other sheet so the ridges of the two sheets are overlapping a bit. Apply a little caulk where they over lap, but not too much. Now nail in the second sheet. Keep doing this until your first row of corrugated metal roofing is finished.

Now it’s time to start the second row above the first row. The bottom of the sheets of metal in the second row should overlap the top of the first row below it by about six inches. Nail in the sheet of metal. Keep adding new sheets overlapping the sheets below them. Also overlap the sheets side to side just like you did in the previous row. Repeat this process until all the rows are finished.

Step Four: Add the Ridge Caps

The final step is to add ridge caps along the lines of the slope’s edges and along the ridges of the roof. The ridge caps will prevent water leakage under the previously installed roofing.

You would now be finished. You’ll see that by following these easy to learn steps, installing your own corrugated metal roofing isn’t really that complicated of a job.
