DIVISION 07
Low-slope TPO single-ply & tapered insulation takeoff
OVERVIEW
WHERE ROOFING BIDS FAIL
Uncalculated tapered crickets, missing parapet wall height flashings, and inaccurate perimeter edge metal details sink roofing contractor margins.
01 MISSED TAPERED CRICKETS
Drainage Slopes & Crickets
Tapered polyiso insulation board fill and valley crickets estimated as flat square footage instead of volume board-feet.
02 PARAPET FLASHING LF
Wall Wraps & Terminations
Vertical wall membrane turn-ups, termination bars, and counterflashing LF uncounted across complex parapet offsets.
03 PENETRATION COUNT
Curbs, Drains & Boots
HVAC unit curbs, pipe boots, pitch pockets, and roof drain assemblies missed when scanning roof plan sheets quickly.
04 FASTENER & ADHESIVE
Attachment Method Costs
Mechanically attached versus fully adhered membrane fastener patterns creating uncaptured material cost swings.

FAQ
FREQUENT QUESTIONS
We add exact roll lap percentages (typically 5–10% based on roll width and seaming specifications) to net roof area, separating field membrane rolls from wall flashing rolls.
We calculate average insulation thickness across tapered zones and crickets, providing total board-feet requirements for 4'x4' or 4'x8' polyiso panels.
Yes. Existing roof removal square footage, wood blocking replacement LF, and deck repair assumptions are itemized separately from new assembly materials.
We need roof plan drawings, roof insulation plans, building elevation sheets, wall section details, roof edge/parapet details, and Division 07 specs.
Standard commercial roofing packages are delivered in 24–48 hours depending on building size and roof complexity.
