Roofing Estimating Services
Our roofing estimating services cover commercial flat roof systems (TPO, EPDM, PVC, modified bitumen, built-up) and residential steep-slope systems (asphalt shingles, standing seam metal, clay/concrete tile). We quantify roofing in squares (100 SF), measure insulation board layers, calculate perimeter and penetration flashing lengths, count roof drains and overflow scuppers, and itemize all accessories including fasteners, adhesives, walkway pads, and edge metals.

Measure all flashing at perimeters, penetrations, curbs, and transitions
Deliver roofing material schedule Excel with marked-up roof plan drawings
Common Roofing Estimating Project Types
Typical construction project types that require professional roofing estimating services.
Commercial Flat Roofs
TPO, EPDM, or PVC membrane systems over polyiso insulation for office buildings, retail centers, and warehouses.
Industrial Metal Roofing
Standing seam or through-fastened metal roof panels for manufacturing facilities, hangars, and large-span structures.
Residential Re-Roofing
Tear-off and replacement of asphalt shingle systems including underlayment, ice/water shield, and ventilation.
Multi-Family Roof Systems
Mixed roof types combining flat membrane sections with sloped shingle areas common in apartment and condo developments.
Roofing Estimating Challenges We Solve
Multiple Insulation Layers
We calculate each insulation layer separately (cover board, base layer, tapered crickets) accounting for different thicknesses and R-values specified at different roof zones.
Penetration & Curb Flashing
Every roof penetration (pipes, ducts, equipment curbs, skylights) requires individual flashing measurement. We count and measure each penetration from the roof plan and mechanical drawings.
Tapered Insulation Cricket Systems
We calculate tapered insulation cricket layouts to achieve proper drainage slopes, accounting for varying panel thicknesses at different roof zones and transitions between drain areas.
