How to Replace a Tile Roof Shingle

Loose tile shingles expose the roof to water damage.

Roofs are a relatively low maintenance component of a house. It is necessary to clean tile roofs regularly to prevent the build of moss and lichen. This dampness may cause rotting or leaks of the tile. Cut back trees over the roof to aid in drying and to prevent damage from falling limbs. If a roof tile is damaged, water may leak into the roof causing interior home damage. Replacing one or several tiles may reduce damage inside the home.

Things You'll Need

• Chisel
• Measuring tape
• Disc cutter
• Adhesive
• Grout
• Putty knife

Instructions

1. Lift up the damaged tile by hitting the grout around it with a chisel and hammer.

2. Remove the broken tile by lifting it. If it is stuck, hit it with a chisel to break it into pieces. Remove any excess adhesive from the roof using a putty knife.

3. Slide a new tile into place, checking that it fits. Measure the spot if the tile doesn't fit and mark the tile for cutting. Cut the tile with a disc cutter if it will not fit.

4. Apply 1/8-inch of adhesive to the back of the tile and set it in place on the roof. Push down on the tile to spread the adhesive.

5. Take the grout sample to the hardware store and have the grout color matched. Allow the tile adhesive to dry for 24 hours. Apply the grout around it using a putty knife.
