Parameter TypesReference
number → a measured number (Roof Area = 2,450)
picklist → a dropdown that drives a value
(Shingle Type → Architectural / 3-Tab)
formula → a calc built from other parameters
MEASUREMENT TYPES (from on-screen takeoff/sync):

↳ these feed real numbers into your formulas
Why it mattersBuild measurements as number/measurement params, options as picklists, then layer formulas on top. EagleView, Hover & Rendr land their values into these.

The Waste MultiplierPattern
( 1 + {Roof Waste %} / 100 )
Full example — squares with waste:
{Roof Area} / 100 * ( 1 + {Roof Waste %} / 100 )
Waste % set to 10 → multiplies by 1.10
Why a parameter, not a numberStore waste once. Bump steep roofs to 15% in one cell and every material line updates.
Auto-Waste by Pitchif() Pattern
if({Predominant Pitch} >= 8, 15, if({Predominant Pitch} >= 5, 12, 10))
Returns15% on steep (8/12+), 12% on medium, 10% on low — automatically, straight from the report's pitch. Tune to your own waste policy.
Waste Strategy — One Pitch-Aware SettingCritical
The principle:
EagleView and Hover both sync slope-adjusted roof
area into JobTread — you do NOT hand-correct for
pitch anymore. Apply waste ON TOP as a single
{Roof Waste %} parameter.
Starting points (tune to your supplier):
• Low pitch (≤ 4/12): 10%
• Medium (5/12 – 7/12): 12%
• Steep (8/12+): 15%
Automate it:
Drive {Roof Waste %} with the Auto-Waste by Pitch
if() formula above — set it once, every material
line re-prices from one cell.
⚠️ Always confirm output against your supplier's
actual waste table before ordering.
❌ Common Formula Mistakes (What NOT to Do)Learning
WRONG: {Total Roof Area} / 100 * 3
Result: 67.88 bundles → quote 67, SHORT 1 bundle
RIGHT: ceil( {Total Roof Area} / 100 * 3 )
Result: 68 bundles → quote safely ✓
---
WRONG: {Total Roof Area} / 100 * 1 + {Roof Waste %} / 100
Result: Waste gets ADDED, not multiplied = wrong math
RIGHT: {Total Roof Area} / 100 * ( 1 + {Roof Waste %} / 100 )
Result: Waste multiplies the squares ✓
---
RULE: Always test with real numbers before deploying. Plug in actual roof area and verify output matches your tool's own waste table.

Worked Example — Real EagleView ReportProof
Roof Area = 6,788 sq ft Pitch = 10/12 (steep)
Ridges = 120 Hips = 315 Valleys = 288
Rakes = 114 Eaves = 276
Squares @ 15% waste: 6788 / 100 * 1.15 = 78.1 sq ✓ matches EagleView's table (78.1)
Shingle bundles: ceil(6788/100 * 1.15 * 3) = 235 bundles
Ridge/hip cap: ceil((120 + 315) / 20) = 22 bundles
Starter (eaves+rakes):ceil((276 + 114) / 110) = 4 bundles
Drip edge (10' stk): ceil((276 + 114) * 1.10 / 10) = 43 sticks
Valley metal: ceil(288 * 1.10 / 10) = 32 sticks
Why this mattersThe squares figure (78.1) lands exactly on EagleView's own waste table — proof the formula logic is right before a dollar is quoted.
Shingle BundlesFormula
ceil( {Total Roof Area} / 100 * ( 1 + {Roof Waste %} / 100 ) * 3 )
ReturnsWhole bundles to order, waste included. {Total Roof Area} is slope-adjusted from EagleView.
Synthetic UnderlaymentFormula
ceil( {Total Roof Area} / 100 * ( 1 + {Roof Waste %} / 100 ) / 10 )
ReturnsWhole rolls. Change
/ 10 to your roll's square coverage (15# felt ≈ 4, 30# ≈ 2).Hip & Ridge CapFormula
ceil( ( {Total Ridges Length} + {Total Hips Length} ) / 20 )
ReturnsCap bundles. Use {Ridges Hips LF} if you have it as a combined formula parameter.
Starter StripFormula
ceil( ( {Total Eaves Length} + {Total Rakes Length} ) / 110 )
ReturnsStarter bundles for eaves + rakes. Drop
{Total Rakes Length} if you only start the eaves.Drip EdgeFormula
ceil( ( {Total Eaves Length} + {Total Rakes Length} ) * 1.10 / 10 )
ReturnsWhole 10 ft sticks with overlap. EagleView also reports a separate measurement if you prefer.
Valley MetalFormula
ceil( {Total Valley Length} * 1.10 / 10 )
ReturnsWhole sticks of valley metal. Skip for woven/closed-cut valleys.
Standing Seam PanelsFormula
{Total Roof Area} * ( 1 + {Roof Waste %} / 100 )
ReturnsPanel square footage (metal is usually ordered by SF or by panel run). For panel count:
ceil({Total Eaves Length} / (panel width in ft)).Install Labor (by square)Formula
{Total Roof Area} / 100 * ( 1 + {Roof Waste %} / 100 )
ReturnsBillable squares (decimal OK). Set unit price = your $/square labor rate.

Hover → JobTread
Native integration · exterior (roof + siding + trim)
Hover orders and syncs natively inside JobTread — measurements pull straight into your parameters, no PDF retyping. Field names below match Hover's exterior glossary (facade, openings, soffit, fascia, trim, corners). Windows and Doors are the only counts that overlap with Rendr. Hover now also supports interior captures; for full interior remodels, the Rendr parameter set below applies.
