Before you let 3 contractors quote your reroof, know what it should cost. Independent NM market pricing per square, per material, per complexity — with the scope defined so you can competitively bid apples-to-apples. No contractor pitch, no free-bid catch.
Current NM market pricing per square (100 sq ft) by material
Complexity multipliers: pitch, stories, cutup, access, tear-off count
Defined scope package to send to 2–3 roofers for competitive bids
Code-upgrade line items required at replacement (per NM 2021 IRC)
Repair-vs-replace second opinion if replacement isn't actually necessary
Written estimate + scope package — no contractor kickback
Site measurement — full roof square footage, per-slope pitch, story count, cutup index, access difficulty. Layer count and tear-off scope (single-layer vs double-layer, tear-off vs overlay eligibility per NM code). Decking probe for soft-decking replacement allowance (rot, delamination). Current NM market pricing calculation: • Material cost (shingles/tile/metal wholesale + retail markup) • Labor cost (per material type at current NM crew rates) • Underlayment, ice/water, drip edge, valley metal, flashing, ventilation, ridge/hip • Dumpster + permit + cleanup + disposal • Complexity multiplier (steep pitch, two-story, cutup, access) • Code-upgrade items (drip edge, ice barrier per R905.1.2, valley flashing) Defined scope package: line-item scope you send to 2–3 roofers so every bid quotes the same job. Repair-vs-replace second opinion — if the roof doesn't actually need replacement, I say so with a repair scope instead.
Homeowners planning a roof replacement in the next 6–24 months. Owners collecting contractor bids who want to know what's fair vs padded. Buyers negotiating a real estate deal where seller is offering a replacement credit. Investors budgeting capex on multiple rental properties. Sellers pricing their listing accurately when the roof is near end-of-life. Insurance claim owners verifying the carrier's Xactimate scope is complete.
Standard Roof Replacement Estimate — $249 With defined scope package for competitive bidding — $349 With repair-vs-replace second opinion — $449 Multi-material or complex historic properties — quoted per building Most estimates are $249–$449. Independent pricing typically catches $3k–$12k of scope padding or lowball missing scope on the contractor bids you subsequently collect.
You should — but AFTER you know what the actual scope and cost range should be. Free contractor bids all trend toward what that contractor wants to sell, which is often more scope than you need at higher pricing than the market supports. Independent estimate first means you can spot padding and lowballs in the bids you collect.
Within 10% of actual bid pricing for standard residential in NM metros. I use current material costs (shingles/tile/metal wholesale + retail), current NM labor rates by material type, and complexity multipliers for pitch, stories, cutup, and access. Where accuracy drops: complex historic buildings, custom architectural specs, or supply-chain disruptions.
Yes — the estimate is priced against a defined scope: tear-off count (layers), decking replacement allowance, underlayment type, ice/water coverage, flashing replacement scope, ventilation upgrade, drip edge, valley metal, and dumpster/permit/cleanup. That's the scope you send to 2–3 roofers for competitive bids on apples-to-apples pricing.
Vigas, canales, parapet caps — NM specialty.
Manufacturer + workmanship defect audit.
Yearly punch-list + service-life estimate.
Pre-listing & buyer due-diligence reports.
I've watched too many neighbors sign contracts they didn't understand for roofs they didn't need. That stops with a written report they own.
