Corrugated Roofing Installation

Metal Corrugated Roof PictureInstalling a corrugated roof on your home can provide many different benefits for the home; including increasing the roofs resistance to wind and rain and providing a roofing surface that will last for many years to come.

A corrugated roofing installation can be accomplished by a dedicated homeowner who is willing to follow the installation instructions to the letter. Disregarding the installation instructions will result in a roof that is not sturdy and will leak when it rains.

Most manufacturers that create corrugated roofing materials will include the installation instructions in with the materials. Different manufacturers may have different installation instructions so it is important to review the information before beginning the installation. There are a number of basic instructions that will remain the same from manufacturer to manufacturer and those basic instructions are outlined below.

Before You Begin

There are a number of items that will be needed to install your corrugated roofing materials correctly and these items should be purchased and on hand before beginning the project. To correctly install corrugated roofing, you will need a claw hammer, steel tape, string, chalk, nails, a nail apron, an electric circular saw, and utility knives. Each of these items can generally be found at your local home improvement store.

Before beginning, you will need to calculate how many corrugated roofing sheets will be needed to cover the entire roof of the home. This can be accomplished by measuring the total square footage of the roof and dividing by the size of each corrugated roofing sheet, taking into account the overlap that is needed for correct installation.

If you need assistance in calculating how many sheets you may need to cover your roof, you can call the manufacturer of the corrugated roofing sheets that you desire with the dimensions of your roof and they will let you know how many sheets you will need to complete the project.

Installing The Roofing Materials

In many cases, the new corrugated roofing sheet can be installed directly over previously used roofing materials. In these cases, it is important for the nails used in the project to be long enough to penetrate both the new corrugated roofing sheet and the underlying roofing materials into the deck of the roof to a depth of at least 1 inch. Anything less and the roofing materials may not be securely attached to the roof.

A chalk line can be drawn on the roof to ensure that all of the corrugated roofing sheets will line up properly during installation. Starting from the corner of the roof, the corrugated sheets should be installed in single rows stretching from one side of the roof all the way to the other side of the roof. After a complete row has been finished, the homeowner should start on the next row traveling in the same direction as when they did the previous row.

For a uniform appearance, the homeowner should start installing the corrugated roofing materials starting at the bottom of the roof and working their way up to the ridge of the roof.

The bottom of the sheets being installed should slightly overlap the tops of the sheets placed in the previous row, allowing any rain or snow to move down the entire roof without getting trapped in any valleys or uncovered areas of the roof. Both sides of the roof should be entirely covered with the corrugated roofing sheets before the ridge is added to the top of the roof.
