Blueprint Takeoff
A roof measured from a calibrated plan set, with sheet references and a revision lock.
Lot 14, Example Ranch Estates, Prosper, TX 75078 (synthetic plan set, planned, not built). Made-up example data, not a measurement of a real home.

Recommended 12% from complexity policy v1: rated moderate (45 of 100 points). A heuristic, not a calibrated rule; adjust for your cut style.
Waste applies to the roof area only. Starter, caps, ridge and valley materials have their own allowances on the material estimate.

How each group is measured
- Shingles: Pitched roof area 4,443 sq ft (2/12 and steeper) × (1 + waste).
- Starter: Eaves 261' 6" + rakes 112' 11" = 374' 5", plus 5% for end laps and corner cuts. The same in every waste column.
- Underlayment: Pitched roof area 4,443 sq ft. Laps are inside each roll's effective coverage; no waste is added. The same in every waste column.
- Ice and water: Eaves 261' 6" × 3 ft + valleys 46' 0" × 3 ft + walls 51' 6" × 1.5 ft = 1,000 sq ft. Estimate setting, not a code determination: one 3 ft course at the eaves, 3 ft centred on valleys and 18 in along walls. Confirm the jurisdiction and manufacturer requirement. The same in every waste column.
- Hip and ridge cap: Hips 123' 1" + ridges 66' 9" = 189' 10". The cap also covers any ridge vent; the vent is its own group, not a second cap line. The same in every waste column.
- Drip edge: Eaves 261' 6" + rakes 112' 11" = 374' 5", plus 5% for corner cuts. Each piece counts at its lapped length. The same in every waste column.
- Valley metal: Valleys 46' 0". Open valleys only; a closed-cut valley needs none. Each piece counts at its lapped length. The same in every waste column.
- Step flashing: Step-flashed walls 9' 6". One piece per shingle course. Headwall, chimney and skylight flashing are not in this matrix. The same in every waste column.
- Ridge vent: 3 ridge runs totalling 66' 9", less 1 ft at each end of each run = 60' 9". Every run is counted; a ventilation plan decides which are vented. The same in every waste column.
- Coil nails: Follows the field-shingle area including waste, because the nails fasten those shingles.
The highlighted 12% column is the waste recommended from the roof's complexity score — a heuristic, not a calibrated rule.
Products in a group are alternatives: choose one per group. Rows are never added together (BOOK-07).
The waste percentage applies to field shingles and the nails that fasten them. Every other group uses its own allowance, the same in every column (BOOK-08).
Each quantity is rounded up once, at the pack, from the unrounded total; no intermediate whole-square rounding (MAT-06).
Coverage values are sample presets pending review (MAT-03). Verify coverage with current manufacturer literature before ordering.
Not included: labour, tear-off and disposal, decking repairs, permits, and any low-slope system until one is chosen.

Scope notes
- Measured from plans: the roof as drawn at the current revisions, not as built. Field-verify dimensions, pitches and heights before ordering.
- A superseded or revised plan produces a new report version with a new lock; this version stays reproducible under RL-E96247DC.
- Overhangs, returns and cornices follow the roof outline as drawn; detail sheets are referenced, not measured.
- Plan north is as drawn on A-101; it has not been checked against the site.
- An absent pitch or height is never assumed: a plane without its note stops the measurement.

Limitations
- An invented plan set for a house that does not exist: not a real lot, plan or designer.
- Quantities describe the roof as drawn. Construction changes and field conditions are not visible in plans.
- Pitches and eave heights are the notes printed on the elevations; they are read, not measured.
- No accuracy or certification is claimed; field-verify before ordering.
