Read the installation manual for your metal shakes to prepare yourself for the installation. Contact the manufacturer of your shakes to get a manual if you don't already have one.
Set up your ladder for easy access to your roof. Place your metal shakes at the bottom of the ladder for convenience.
Prepare your roof. Metal shakes install on top of roof sheathing or a roofing membrane, as would shingles or other types of metal roofing. Remove any existing roof shingles or panels with a hammer or your drill.
Clean the roof for installation by sweeping away all loose debris with your broom.
Bring your first row or set of metal shakes to your roof using your ladder. Regardless of the type of shakes you use, they usually install horizontally in rows or sections.
Install the first metal shake at the bottom corner of your roof. Affix it to the roof sheathing or weatherproof membrane using your drill and fasteners recommended by your installation guide. Base the placement of the shingle on the manuall; whether you install the first shake in the bottom right or bottom left corner of a room might depend upon the orientation of shake seams.
Install the rest of the first horizontal row of shakes across the surface of the roof, attaching each unit as recommended by the manufacturer using your drill.
Bring the second row of shakes to the roof. Align the first shake of the second row over the first shake of the second row as instructed by the manual. Properly setting rows together ensures optimal protection from moisture presentation.
Affix the shake with your drill, repeating the process for each shake in the second row. Repeat this process, carefully following manufacturer's installation instructions, for each subsequent shake and row of shakes until you cover the whole roof.
Follow any special instructions for attaching shakes to the apex of a roof, or the point at which the sides or a roof come together in a point.
Apply weatherproof sealant or caulk as recommend by the manufacturer of the shingles to the gaps between individual shakes or rows for additional protection.
