This is a really simple and unexpensive way to make roof tiles. For this we will use red foami and the following tools:

Supplies

Scissors
Ruler
Plier
Pencil
Lighter
Slim brush
2 metallic pipes (one with a bigger diameter than the other)
And a blade knife

Step 1: Wide and Lenght

For this particular roof tile model i will use stripes of roughly 1 cm (wide) aproximately and the lenght will be determined by the metallic pipe we will use to give shape to the material.

Step 2: Material Process Part 1

In the first place we put the foami over the smaller pipe and introduce it both inside the bigger pipe leaving a piece outside to pull it out later. And with the pliers we grab the whole piece to be able to heat it up a few seconds, we must avoid long or direct exposure to fire, otherwise our foami could melt (be carefull !).

Step 3: Material Process Part 2

Insert the brush (meanwhile the pipe is still warm) and press a little bit down to get the desired curvature. Remove the brush and the inner pipe, after that also retrieve the foami piece and notice the curvature in it.

Step 4: Measuring and Spliting the Tiles

On this step we take the ruler and made a mark at 1.5 cm over the foami stripe. With the scissors we split the segments.

Step 5: Final Product

And this is the final product. We can use it to build our miniature roof ceilings, we can add paint or wear signs to give a more accurate result to the tiles.
