In this tutorial I shows you a bunch of different ways you can make the roofs of the medieval buildings. This is a lot of fun. You can use small pieces of wood or you can cast the roofs with plaster.

This picture is a great example of two of the techniques you can use to make the roof.

First Lets take a look at the upper roof of the building shown above. I cast that out of plaster of paris and first I made a mold. I will show you that whole process from start to finish. It's actually pretty easy and it only takes a few different materials.

Laid out some clay to form a rough roof shape and size. I did this on a piece of glass. And then I carved a piece of wood to have this shape in it. And I used that as a tool to mold in the random shingle shapes.

Then I used some pieces of wood and hot glued them around the clay form to create a box. I used a hot glue gun to glue it all together and to seal all the seams along the bottom of the wood. all the way around. This way the mold material doesn't leak out.

To make the mold you have a few different options. I used a product called Instamold. It is cheap and very easy to use. Just mix it with water and pour it in the mold we made.

INSTAMOLD - This is the exact stuff that I use. It is available on Amazon.com

And there we go. The Instamold has been poured and in half an hour we can remove it.

Quick note about mold removal. Sometimes these molds can get a little sticky and it can be tricky to remove the rubber mold from the clay. You can use a product called mold release to aid this. It is a spray on. You spray it on the clay before you pour the rubber. It helps.

And if you really wanted to be precise about it you might want to first seal the clay roof with some kind of a sealant. Then you spray on the mold release.

Carefully separate the mold from the clay and we have a beautiful mold that we can use many times to cast plaster roofs.

Now mix up a small batch of plaster of paris or hydrocal and slowly pour it into the mold.

One of the things you have to watch out for is bubbles forming in the plaster so once it is poured you should rap on the table a whole bunch of times. This loosens any bubbles and causes them to come to the surface.

And there you go. The plaster is poured into the mold. If you are still having trouble with air bubbles you can press on this with a flat object like a piece of wood or foamboard. That often helps. Just don't press so hard that the plaster squirts out of the mold.

This picture shows how the bubbles formed in one of my roof molds. So, if you have trouble with this just keep at it. Sometimes making the plaster a little thinner also helps.

Okay, lets make the wooden shingle thatched roof
