Steep-slope shingle and low-slope membrane systems quantified from your roof plan — squares, flashing detail, insulation, and drainage, counted the way a roofing sub actually bids the job.
A roofing takeoff covers total roof area by system type (steep-slope shingle, standing seam metal, or low-slope TPO/EPDM/modified bitumen), flashing linear footage at every edge, valley, and penetration, insulation by R-value zone, and drainage — scuppers, drains, and crickets. We separate roof areas by pitch and system since labor and material rates differ significantly between them.
Penetration and flashing detail is the most commonly underestimated part of a roofing bid — every HVAC curb, pipe boot, and parapet detail adds real labor that a simple square-footage takeoff misses. We quantify these individually, not as a blanket percentage add-on.
Whether you're bidding a steep-slope residential re-roof or a commercial low-slope membrane system, the takeoff runs through the same AI-first, engineer-reviewed process described on How It Works — reviewed by an estimator who reads roof details for a living.
