Corrugated metal roofing is designed to last longer than a traditional asphalt roof. There are some steps that you need to follow when performing this task of replacing a corrugated metal roof. Any type of roof replacement, whether it is a corrugated metal roof or an asphalt roof, involves some level of risk. This is important to mention and be aware of because you need to make sure that you work carefully and safely whenever you are working above the ground.

If possible, you should work with an assistant or colleague who is as if not more knowledgeable about corrugated roof installation. This will ensure that the repair will be done right and that you will avoid any undue harm or serious injury as a result of the roof replacement. This article describes the steps, including the tools and materials needed to replace the roof.

Step 1: Purchase Materials for Replacement of Corrugated Metal Roof

Go to a home improvement center, or other retailer that sells roofing materials, and purchase the roofing shingles or panels for your corrugated metal roof. The installation of these panels should be similar to the installation of an asphalt shingle roof except for the fact that the corrugated metal shingles are heavier that the asphalt shingles. 

Step 2: Remove the Old Corrugated Metal Roof

With a claw hammer remove the old corrugated metal roof. Work from the top of the roof to the bottom in order to pull up the shingles and stack them on the roof. Because the corrugated metal shingles are heavy, work carefully and do not throw any of the discarded shingles to the ground, in order to prevent anyone below from getting hurt or causing any damage.

Step 3: Place the New Corrugated Roof Shingles on the Roof

With the old shingles removed from the roof and hauled off in loads to the ground, place the corrugated metal shingles on the roof. Secure the shingles with a nail gun, or hammer and nail. The fasteners that you use to affix the corrugated metal shingles to the roof should be strong enough to drive through the textured metal. If you have questions concerning the type of nails to use in this installation, ask a home improvement specialist to give you some guidance.

Step 4: Attach the Flashing to the Corrugated Metal Roof

The flashing is the strip that binds seams in your roof to make it difficult for water to seep in the roof and underneath the shingles. You need to apply a strip of flashing throughout the roof wherever there is a seam present in order to prevent your roof from being damaged by water. With the flashing attached, carefully climb down from the roof and remove any of the waste material that was left behind from the removal of the old corrugated metal roof and the installation of the new one.
