Part 7 — The Roof Plan | Sheet by Sheet

  The roof plan is the most underestimated sheet in any residential set. It looks simple from above — just a bunch of lines and arrows.  But those lines represent ridges, valleys, hips, and overhangs that the framing crew has to translate into three dimensions. Get the roof plan wrong and the framing crew gets it wrong with you. What it shows: Ridge lines, hip lines, and valley lines Roof slopes and pitch callouts Overhangs and eave dimensions Crickets and saddles at chimneys and vertical walls Roofing material and underlayment notes Skylight and roof penetration locations Downspout and gutter locations Key terms builders need to know: Ridge — the highest horizontal line where two roof slopes meet at the top.

Part 3 — CD & Permit Sets: Drawing It the Way It Gets Built | Blueprint to Build

What a complete set covers:
• Site plan, floor plans, all four elevations
• Building and wall sections
• Roof plan and framing notes
• Energy compliance documentation
• Door, window, and finish schedules
• Structural callouts per local code


What makes it actually work:
Dimensions that don't need interpretation. Details that reference back to plans. Notes that are specific, not generic. Energy compliance calculated, not assumed.

When a contractor builds without calling the office — good set. When the permit clears first submission — great set.
