What Is Roofing Estimating?
Roofing systems demand extreme precision in calculating roof slope pitch multipliers, tapered insulation slope layouts, parapet wall flashing heights, and penetrations (pipe boots, pitch pans, skylights). An error in wind uplift fastening patterns or polyiso thickness can cause major bid discrepancies.
At F&K Estimatings, our roofing estimators use Roofmaster, Edge, Planswift, and Bluebeam Revu to measure planar roof areas, calculate exact slope pitches, model tapered insulation drainage crickets, and compile contractor-ready material order schedules.

Roofing Estimating Service Scope & Material Quantities
Select a category below to explore our specific measurement parameters and deliverable formats.
Division 07 TPO, EPDM & PVC Membrane Systems
Complete takeoff of commercial flat roofs including membrane rolls, bonding adhesives, fasteners, and plates.
Deliverable Format
Squares (SQ), roll counts (10x100, 12x100), adhesive gallonage, and fastener box counts.
CSI MasterFormat Division 07 Roofing Standards
Every roofing estimate follows CSI MasterFormat Division 07 standards and complies with NRCA (National Roofing Contractors Association) guidelines.
Our takeoff schedules separate low-slope, steep-slope, insulation, and sheet metal into distinct packages.
Thermoplastic Membrane Roofing (TPO/PVC)
Heat-welded single-ply reflective roof membranes and accessories.
Elastomeric Membrane Roofing (EPDM)
Ethylene propylene diene monomer rubber roof systems.
Roof & Deck Insulation
Polyisocyanurate flat, tapered, and cover board insulation.
Asphalt Shingles
Architectural, laminated, and designer steep-slope shingles.
Metal Roof Panels
Standing seam, architectural metal, and concealed clip panels.
Roof Specialties

Pitch Multipliers & Tapered Insulation Modeling
Roofing estimating requires calculating exact pitch multipliers (e.g., 6:12 slope = 1.118 multiplier; 12:12 slope = 1.414 multiplier) and modeling tapered polyiso crickets to ensure positive drainage toward internal roof drains.

Roofing Takeoff vs. Complete Roofing Estimating
Understanding whether your team needs raw quantity measurements or a fully priced bid estimate helps you order the exact service you require.
F&K Roofing Estimating Service Quantification & Review Workflow
Our systematic 7-step engineering process eliminates missing elements, prevents duplicate counts, and delivers defensible estimates.
Roof Plan & Detail Audit
We review roof plans, wall sections, parapet details, drain schedules, wind uplift requirements, and Division 07 specs.
Planar Measurement & Slope Pitch Adjustment
Using digital takeoff software, we measure planar roof areas and apply geometric slope multipliers to establish true area.
Insulation & Tapered Cricket Modeling
We calculate flat polyiso base layers, tapered slope panels, drain sumps, and cover boards.
Membrane & Underlayment Takeoff
We calculate TPO/EPDM membrane rolls, side/end lap allowances, starter strips, and underlayments.
Perimeter Sheet Metal & Flashings Takeoff
We measure parapet coping caps, drip edge, gutters, downspouts, scuppers, and pipe penetration boots.
Labor Crew & Equipment Allocation
We calculate tear-off and install labor hours, safety tie-offs, rooftop telehandler/crane logistics, and dumpsters.

Roofing Estimating Service Elements We Quantify
How Roofing Estimating Service Costs Are Calculated
Material and labor costs fluctuate drastically by project geography, supplier logistics, trade union jurisdictions, and site conditions. We do not use flat national averages.
Our cost database integrates regional material supplier pricing, union prevailing wage scales, open-shop labor rates, and local equipment rental benchmarks across all 50 U.S. states.
Roof Slope Pitch & Walkability
Steep pitches (8:12 and above) require roof brackets, scaffolding, and harness tie-offs, reducing daily crew productivity.
Wind Uplift & Fastener Density (FM 1-90 / 1-120)
High wind zone specifications require 50% more fasteners and plates per board in corner and perimeter roof zones.
Tear-Off vs Single-Ply Overlay
Tearing off multiple existing asphalt/gravel roof layers doubles labor hours and requires hazardous dumpster disposal.
Sheet Metal & Coping Finishing (Kynar 500)
Factory Kynar 500 pre-finished metal copings carry a premium over standard mill finish aluminum.
Manufacturer NDL Warranty Requirements
20-year and 30-year No Dollar Limit (NDL) manufacturer warranties mandate certified inspections and specific component assemblies.
