In a traditional hip roof, the king rafter would be the same length as the common rafters you are using. However, since sheds take on all shapes and sizes, you should not take this rule as set in stone. That new vertical and the horizontal line you drew extending toward the inside of your shed are the cuts you’ll make – a triangle. This notch allows the beam to rest flush onto the top plate. Is it necessary? While you may be tempted to avoid the admittedly tedious process of making birdsmouth cuts in each rafter, don’t do it. Let’s get down to business and build some rafters. Now that you’ve got a decent idea of how big your rafters are going to be, we’ll go through how to build them step by step. First, you’ll want to find the pitch of your rafters, which will help you find the length of your rafters. Use this calculator to find your rafter length.

After all, it’s the job of the walls to hold the roof up. This prevents the rafter from potentially shifting, causing your roof to sag, or worse, collapse inward.

To start, I already know that my rafter length is going to be 5’ 3 ½”. I’ll use my speed square to measure my first cut on one end of my 2×4 rafter. I’ll use the corner of the speed square on one edge of the 2×4, where it says “pivot”. I’ll then rotate the square on the pivot until the 4 is lined up with the outside edge of the rafter. Get some scrap 2×4 pieces. Cut four of them into lengths of a couple of feet or so. Screw each piece so that there is one above and below each rafter. Do it carefully so that rafters are not out of place. You can now remove your rafters and insert another pair – you’ve created a jig to cut your birdsmouth joints.x2" / 100mm x 47mm 5"x2" / 125mm x 47mm 6"x2" / 150mm x 47mm 4"x4" / 100mm x 100mm 6"x6" / 150mm x 150mm
