Roofing Estimating Services in New York

Flat and pitched roofing estimates — membranes, shingles, metal roofing, insulation, flashing and drainage — for new construction, replacement and storm damage across New York.

QUICK ANSWER

What Is a Roofing Estimate?

A roofing estimate calculates the roof area, slopes, layers, insulation, membrane or shingle materials, flashing, edge metal, drains, penetrations, tear-off, disposal and labor needed to install or replace a roof. Roof area is measured in squares (100 square feet) and adjusted for pitch and waste.

Most New York City buildings have low-slope roofs, while homes upstate and on Long Island often have pitched roofs. Our roofing estimates cover both.

Key Facts

OVERVIEW

Roofing Estimates for Flat and Pitched Roofs

Roofing bids are won and lost on details: parapets, crickets, tapered insulation, drains, penetrations, curbs and flashing heights. Our estimators measure each roof area, calculate slopes, and count every penetration and edge condition so the estimate matches the real roof.

We estimate modified bitumen, TPO, EPDM, PVC, built-up, green roofs, asphalt shingles, slate and standing-seam metal for residential, commercial and industrial buildings. Storm and insurance roof estimates are available through Xactimate Estimating Services.

Roofing coordinates with insulation, framing, masonry parapets and HVAC curbs and equipment.

ESTIMATING GUIDE

Roof area: squares (100 SF)
Insulation: SF by thickness / board feet
Flashing and edge metal: LF
Drains and penetrations: each
Tapered insulation: SF by taper zone
Tear-off: squares per layer

NEW YORK COST DRIVERS

Roofing Cost Factors in New York

Green Roof and Solar Requirements

NYC Local Laws require sustainable roofing on many new buildings and major roof replacements.

Snow Loads and Ice Damming

Upstate roofs need ice and water protection and stronger detailing for snow.

Hoisting and Roof Access

Materials often must be hoisted or carried through buildings in the city.

Coastal Wind Exposure

Long Island and coastal areas need enhanced attachment for wind uplift.
