I searched and searched on the internet for some other guy who made his own shingles. I was amazed that I couldn’t find a single post. So maybe this will help somebody else out who is in a similar situation as me. What I was interested in was the pattern. I’ve never installed any kind of shingles before. So I searched for pictures and looked at a bunch of them. I also looked at the available sizes on the
James Hardie website. For individual shingles, it seems to boil down to 12, 8, and 6 inch widths. This just did not seem like enough variation to me. There are more than three widths when you get the 4-ft panels. But since I was going to make my own, I needed to keep it somewhat simple. My local Home Depot only stocked primed siding in an 8.25 inch width. But Lowes just happened to stock the 12 inch width too. I came up with a pattern on graph paper that involved 12, 8, 6, and 4-inch widths. All I had to do was rip a 12 and an 8 to get the other widths I needed. This pattern took me awhile to figure out (see pic). But it works perfectly. Yes my 8 is actually 8.25 inches but it doesn’t matter as long as you are consistent. Also note that each row is offset 16 inches, similar to what is stated in the installation instructions from the website. In case the picture is not clear, the pattern is 12, 8, 4, 6, 8, 4, 6 and 8.
