Shingle, Tile, TPO, EPDM & Metal

ESTIMATION SERVICES FOR ROOFING

Roofing is one of the most critical scopes in protecting a building—and one of the most vulnerable to estimating errors. At Preconstruction Estimation, we specialize in roof system takeoffs for shingle, tile, TPO, EPDM, metal, and built-up systems. We measure slopes, hips, valleys, ridges, and edges to the square inch, not just square foot.

Our reports include quantities for underlayment, membranes, flashing, fasteners, drainage systems, and trim, aligned with manufacturer specs and local codes. We also account for material waste and accessory needs based on layout complexity and roof style.

From high-end residential to commercial flat roofs, our estimates ensure that your scope is airtight—literally and financially. We deliver fast, accurate roofing takeoffs that help you win jobs while staying protected from missed costs.
