Hip Roof / Hip & Valley Rafter Quantity Verification Checklist PDF

Full QC Checklist+

Verify dimension/pitch inputs, hip/valley geometry and cuts, jack rafter layout, and code/safety sign-off.

✓21 Inspection Points

✓4 Verification Categories

✓Dimension & Pitch Inputs+

Building (or wing) width and length confirmed from actual field measurements or plans, not assumed
Roof pitch entered matches the actual design intent, and is the SAME on both roof planes
Correct roof section type selected (Hip Roof vs. Hip & Valley wing/addition)
Rafter spacing matches the roof sheathing's span rating and the actual roof load for this project
Local building code edition, wind/seismic zone, and snow load confirmed before finalizing
Same overhang entered applies correctly to both common AND hip/jack rafter tails for a continuous fascia line

✓Hip / Valley Geometry & Cuts+

Confirmed this calculator gives hip/valley rafter LENGTH and plumb-cut angle only, not compound side-cut/backing-bevel angles
Hip/valley rafter total length checked against available stock lengths before ordering
If width and length are equal (a pyramid hip), confirmed there is no ridge board and all 4 hips converge at a single apex
Structural support for the hip rafter's load path (down to a corner post/header) verified where needed
Hip/valley rafter lumber size confirmed adequate for its actual (longer) span, not just matched to the common rafter size
Common rafter count confirmed to include king common rafters, not just the in-line commons along the ridge

✓Jack Rafter Layout+

Jack rafter length series (shortest to longest) verified against actual layout before cutting
Jack rafter side-cut angle (where it meets the hip/valley) confirmed separately, not computed by this calculator
Jack rafter count and lengths confirmed to apply identically on both walls meeting each hip/valley corner
Jack rafters (like commons) installed crown-up, and checked individually before cutting the full series

✓Code, Safety & Sign-Off+

Birdsmouth notch depth checked against the commonly-required 1/4-of-depth limit for this rafter size
Any hip/valley beam carrying unusually long spans or heavy point loads reviewed by a structural engineer
Permit and framing inspection requirements confirmed before roof sheathing covers the rafters
Unequal pitches, irregular building shapes, or any non-standard condition reviewed by a designer or structural engineer
Total rafter count reconciled against the actual architectural roof plan before ordering lumber

Inspection Notes+

Use the latest approved drawings, specifications, and site measurements.

Complete all critical checks before proceeding to the next work stage.

Record deviations and confirm rectification where required.

No. It supports verification but does not replace approved drawings, specifications, codes, manufacturer requirements, or professional inspection.
