How to Use This Tool
Enter length, low height, and slope
Set the wall length and the height at the low end, then define the single slope by roof pitch or by entering the high-end height - the tool derives the angle either way. Shed roofs, lean-tos, and half-gables all frame this way.
Set stud spacing and add openings
Choose 16 or 24 inch on-center spacing and drop in any window or door openings at their rough-opening sizes. Layout runs horizontally from the low end starting at 15-1/4 inches, so sheathing breaks stay on stud centers regardless of the slope.
Verify stud lengths and export
The tool draws the wall with every stud length calculated from its position along the slope and the bevel angle marked at each stud top. Export the blueprint and cut list, set the saw to the listed bevel, and cut the entire wall in one session.
Single slope stud math
A single slope wall is the simplest rake: one plate angle, one bevel setting, and stud lengths that grow linearly from the low end to the high end. Each stud is the low-end height plus its distance from the low end times the tangent of the slope angle.
If you know both end heights instead of the pitch, the tangent is just the height difference divided by the wall length - the tool accepts either input and shows the matching pitch and bevel angle.
stud height = low height + (distance from low end x tan(slope angle))
tan(slope angle) = (high height - low height) / wall length
bevel at each stud top = slope angle
at 16 OC, each stud grows by 16 x tan(slope angle) over its neighbor
Frequently Asked Questions
What is a single slope rake wall used for?
Any structure with a shed-style roof: lean-to additions, single-slope sheds, modern shed-roof houses, porch enclosures, and the side walls under a half-gable. The two side walls of a shed-roof building are both single slope rakes, mirror images of each other. The Angled Wall Builder frames one wall; flip the layout for the opposite side and the cut list is identical.
How do I figure the slope if I only know the two wall heights?
Divide the height difference by the wall length using the same units. A wall 144 inches long that runs from 84 inches to 108 inches high rises 24 inches over 144, so tan of the slope is 0.1667 - a 2/12 pitch, with a bevel angle of 9.46 degrees. The builder accepts both end heights directly and shows the resulting pitch, so you never have to do the trig by hand.
What is the minimum pitch for a shed roof over an angled wall?
Asphalt shingles generally require at least 2/12 pitch with special underlayment, and 4/12 or steeper for standard installation. Metal depends on the seam type: standing seam panels can go as low as 1/4:12 per IRC R905.10.2, while exposed-fastener panels need at least 3:12. Membrane roofs handle near-flat slopes. Pick the roofing first, because the minimum pitch it allows sets the height difference your angled walls must produce. Check manufacturer specs and local code for the final call.
Do studs in an angled wall get cut at an angle on both ends?
No - only the top. The bottom of each stud sits square on the level bottom plate; the top gets a single bevel cut at the slope angle so it beds flat under the sloped top plate. Measure each stud to its long point. The one saw change from a normal wall is dialing in the bevel once, then working through the cut list from shortest to longest.
How do openings work in a sloped wall?
Windows and doors stay level - the header and sill are horizontal even though the top plate slopes. Kings and jacks frame the sides as usual, and the cripples above the header are each a different length because they die into the sloped plate with a bevel cut, just like the common studs. The builder calculates every cripple length above the opening and includes them on the exported cut list.
Can I use the Angled Wall Builder for a full gable and back-to-back slopes?
A full gable peaks in the middle with slopes falling both directions - that is the Rake Wall Builder's job. Use the Angled Wall Builder when the wall slopes in one direction end to end: shed sides, lean-tos, and half-gables. If you are unsure, look at the top plate: one straight sloped line means angled wall; two lines meeting at a peak means rake wall.
