At the time I didn't need any roofs for circular buildings but I thought - I could make that and I definitely should if the opportunity arises. I mentally filed the idea away for future coolness. Fast forward 15+ years and what do you know? I've got a circular building that needs a roof!
The scaly shingle idea wasn't a winner in my wife's mind though. She never saw the original picture and I guess I wasn't selling my version very well because I never got more than a lukewarm reception to it. We pondered many ideas for roofing material including used tires or recycled highway signs cut into shingles. I couldn't shake the vision of that back cover though and in the end the dragon scale idea prevailed.
Step 1: Ye Olde Materials and Tools Lists
Next, the decision is yours go with real dragon scales or an alternative? I didn't have any dragons that happened to be shedding available so I chose to go with the next best thing- rolled roofing. It’s an asphalt material that comes in three foot wide rolls and is one of the cheapest roofing materials per square foot you can use to cover your roof with. You can get it at any big box store.
The only other thing you need is roofing nails. They are short galvanized nails and you are going to be using a bunch of them. How many is hard to estimate but you'll get a feel for it as you get into the project.
The tools I used are pretty simple -
Carpenter's pencils- several of these
Tin snips for cutting the roofing
Carpenter's tool belt to hold the nails
