You've got a $4M mixed-use job with a roof scope that needs pricing by Friday. Your roofing sub's estimate lands in a PDF, your own takeoff lives in a separate app, and neither one talks to the steel, framing, or electrical numbers sitting in your main bid. That disconnect is where roof estimating software either saves your week or quietly costs you margin.
Most roof estimating software gets built for single-trade roofing companies — not for general contractors juggling a roof scope alongside eight other trades on the same bid. This article ranks the tools that actually work for GCs, not just roofers, and tells you which one fits your specific workflow. If you want the feature checklist rather than the rankings, see our guide to roofing estimating software features.
Quick Picks: Best Roof Estimating Software for GCs
If you're a general contractor who needs roof estimates to plug into a full project bid — not live in a standalone app — Struvia is the best roof estimating software for 2026 because it takes off the roof with every other trade on the plan set, prices it from your own price book, and levels roofing sub bids against that same scope.
The right tool depends on how you work and what else you're estimating.
- Self-perform GC with in-house roofing crews: Struvia or STACK — both handle roof takeoff alongside your other self-performed scopes without exporting to a third app.
- Comparing multiple roofing sub bids: Struvia — built specifically for bid leveling across subs, not just measuring your own takeoff.
- Small residential crew, roofing-only: Roofr — purpose-built aerial measurement for single-trade roofing shops.
- Budget-conscious GC estimating occasional roof scopes: Free tools paired with manual takeoff (more on this below) or STACK's free tier.
- Enterprise GC already running Autodesk Construction Cloud: Autodesk Takeoff — native integration beats bolting on a separate roofing tool.
How to Score Roof Estimating Software Before You Buy
Every roof estimating tool claims to save time and improve accuracy. Here's the framework to actually test that claim before you sign a contract.
Takeoff Speed and Measurement Accuracy
A tool that measures a 3,200 sq ft roof in 90 seconds but misses a 6/12 pitch adjustment costs you more than a slower, accurate one.
Test any tool on a roof with at least two pitch changes and one dormer. If it can't calculate waste factor automatically for architectural shingles (commonly 10-15% on cut-up roofs), it's not ready for real bids.
Pricing Transparency and Contract Terms
Watch for auto-renewal clauses and multi-year lock-ins when vendors hide pricing behind sales calls. Enterprise tools like Procore often require custom quotes because pricing scales with company revenue and user count, which is a different model than per-seat SaaS tools like STACK.
Ask directly: is this per-seat, per-project, or flat annual? Multi-year contracts with auto-renewal clauses are common in this category and can lock you into a tool that stopped fitting your workflow 18 months ago.
Bid Leveling and Subcontractor Management Fit
Most roof estimating software measures your own takeoff well but ignores sub bid comparison entirely. If you're a GC who subs out roofing 80% of the time, that's the wrong priority.
You need a tool that lets you drop four roofing sub proposals next to your own quantity takeoff and see where scope — not price — creates the spread.
Integrations With Your Existing Estimating Stack
The STACK vs Procore estimating debate comes up constantly because both integrate differently with roofing-specific data. STACK handles takeoff-heavy roofing scopes well; Procore leans toward project management with estimating as an add-on module.
If you're currently in Bluebeam for markups, look for Bluebeam alternatives for estimating that keep your PDF markup habits but add real quantity takeoff — Bluebeam wasn't built for automated pitch and waste calculations.

Roof Estimating Software Reviewed: Pricing, Pros, and Cons
Struvia: Best for GCs Who Sub Out Roofing
Struvia takes off the roof from your plan set alongside every other trade on the job, prices it from your own price book, and delivers the estimate in your own Excel template with your formulas intact. When roofing sub bids come in, its bid leveling lines them up against the same scope and flags gaps and exclusions, like the missing parapet flashing in the example further down.
Pricing is usage-billed credits with no seats or subscription. Reading the plan set is free, and new accounts start with 600 free credits.
Poor fit: residential re-roof contractors working from satellite imagery. Struvia works from plan PDFs and doesn't produce aerial measurement reports, so a shop selling re-roofs directly to homeowners is better served by Roofr. Switching trigger: you're retyping a roofing sub's numbers into your master bid on every job.
Roofr: Best for Standalone Residential Roofing Crews
Roofr built its reputation on aerial measurement reports that roofing companies can turn around in minutes. If you're a single-trade roofing contractor selling directly to homeowners, it's a strong, focused tool. The Starter plan is free with pay-per-report measurements (about $19 each), and paid plans run roughly $209 to $349 a month with unlimited users.
The problem for GCs: Roofr doesn't connect to your framing, siding, or electrical estimates. You're stuck exporting numbers manually into whatever tool runs your master bid, which reintroduces the exact disconnect this article opened with.
Best-fit customer: a roofing subcontractor or residential re-roofing company. Poor fit: any GC managing roofing as one line item in a larger project.
STACK: Best for GCs Who Need Multi-Trade Takeoff
STACK earns its spot because it treats roofing as one scope among many, not the whole product. You can take off a roof, a foundation, and a framing package in the same project file.
For a full breakdown of pricing tiers and feature depth, see our STACK construction software review. The short version for roofing specifically: STACK's pitch and waste factor calculations are solid, but you'll spend more setup time than you would in a roofing-only tool.
Switching trigger: if you're currently juggling Roofr for roofs and a separate tool for everything else, STACK consolidates that into one file.
Autodesk Takeoff: Best for Enterprise GCs Already on Autodesk Construction Cloud
If your company already runs Autodesk Construction Cloud for document control and BIM coordination, Autodesk Takeoff (now being folded into the Autodesk Forma brand) is the logical roof estimating add-on. It pulls directly from the same model federation your project engineers already use.
Full cost breakdown lives in our Autodesk Takeoff pricing guide — list price is $1,250 per user per year, and it makes the most sense when you already pay for the rest of the ACC stack.
Poor fit: a $5M-revenue GC not already on Autodesk. The ecosystem lock-in isn't worth it without the existing investment.
Togal AI: Best for Fast AI-Powered Roof Measurements
Togal AI reads plans and auto-generates quantity takeoffs, including roof area and pitch, in a fraction of the time manual takeoff requires. On a simple gable roof, the speed advantage over manual tracing is real. Togal stops at quantities, though: it has no cost database and doesn't produce a priced estimate, so you export to Excel and price elsewhere. Growth runs $299 per user per month, billed yearly, and teams of four or more move to a custom Business plan.
The tradeoff shows up on complex geometry. Multiple dormers, valleys, and mixed pitches are where AI-read plans need the most correction. Verify AI output against at least one manual spot-check per project until you trust the tool on your specific roof types.
PlanSwift: Best Legacy Option for Manual Roof Takeoffs
PlanSwift has been around long enough that plenty of estimators learned takeoff on it before AI tools existed. It's a legitimate Bluebeam alternative for estimating because it adds real quantity extraction on top of PDF markup, something Bluebeam alone doesn't do.
You own every line item — no automated guesswork, no black box. That's also the limitation: every measurement is manual, so a full commercial roof takeoff can take hours longer than an AI-assisted tool.
Best-fit customer: an estimator who wants full control and doesn't mind trading speed for certainty.
Buildertrend: Best for Residential Roofing Project Management, Not Estimating Accuracy
Buildertrend markets itself heavily on client communication, scheduling, and change orders — and it's genuinely good at those things for residential roofing contractors managing homeowner relationships. Where it falls short is granular estimating math.
Buildertrend's estimating handles basic square footage but lacks the pitch-specific and waste-factor automation that dedicated takeoff tools offer. If your business lives and dies on precise material counts, Buildertrend shouldn't be your estimating engine — use it for project management and pair it with a real takeoff tool.
Why Roofing-Only Software Breaks Down on Multi-Trade Projects
Roofing-specific software reviews almost always skip this: a GC doesn't estimate a roof in isolation. The roof scope has to reconcile against structural loads, gutter and drainage tie-ins, and whatever the roofing sub actually priced — which rarely matches your takeoff line for line.
Standalone tools like Roofr solve the measurement problem. They don't solve the "does this sub bid actually match my scope" problem, which is the one that actually costs GCs money on bid day.
The Subcontractor Bid Leveling Problem With Roof Scopes
Picture a 6-story mixed-use build with a 22,000 sq ft low-slope roof. You send the scope to four roofing subs and get bids ranging from $198,000 to $261,000 — a 32% spread on paper.
Line the bids up side by side and the real story emerges: two subs included tapered insulation for drainage, one didn't spec a warranty upgrade the owner requires, and one quietly excluded parapet flashing. The price spread is mostly a scope spread wearing a price disguise.
A Chicago-based estimator told us something that's stayed with us: "I stopped comparing roofing bids by the bottom line years ago. Now I build my own takeoff first, then every sub bid gets measured against that — not against each other." That's bid leveling done right, and it's exactly the workflow roofing-only software was never built to support.
Free and Low-Cost Roof Estimating Options for Small Contractors
If you're running two or three small jobs a year with roof scopes under $50,000, you probably don't need a $200/month subscription. Google Sheets templates paired with manual pitch multipliers still work — slowly, but accurately if you're careful.
For a full rundown of what's genuinely usable at $0, including which "free" tools have hidden per-project caps, check our guide to free construction estimating software. The short version for roofing specifically: most free tiers cap you at 1-3 active projects or strip out waste-factor automation, which is exactly the calculation you can't afford to get wrong.
Budget-conscious GCs scaling past a handful of roof scopes per year will hit that ceiling fast — that's the point where a paid tool starts paying for itself in reduced rework.
What Roof Estimating Software Actually Costs in 2026
Pricing in this category splits into three tiers: monthly SaaS (roughly $200 to $350 a month, per seat or per company), one-time licenses (PlanSwift's is $1,595), and enterprise custom pricing (Procore, Autodesk) that scales with company revenue and user count.
The trap most GCs fall into: signing an annual contract for a multi-trade platform when they only needed roof-specific takeoff. Procore's estimating module, for instance, isn't sold standalone — it's bundled into broader project management pricing, which we break down fully in our Procore estimating pricing guide.
Autodesk follows a similar bundling pattern through Construction Cloud. If you're evaluating that ecosystem specifically for roof takeoff, our Autodesk Construction Cloud pricing breakdown covers the tiers in detail rather than repeating them here.
More AI takeoff tools means more sales calls promising accuracy numbers. Verify them yourself on one of your own past roof scopes before you buy.
Frequently Asked Questions
Is there roof estimating software that integrates with Procore?
Yes — several takeoff tools, including STACK and Autodesk Takeoff, offer integrations or data export compatible with Procore's project management workflow. Native, real-time sync is less common; most integrations involve exporting quantities or line items rather than live two-way syncing.
How accurate is AI roof measurement?
On simple gable and hip roofs, AI takeoff tools are generally reliable. Accuracy drops noticeably on complex geometry with multiple dormers, valleys, or mixed pitches, so a manual spot-check on your first few AI-measured roofs is worth the extra 15 minutes.
What's the cheapest roof takeoff tool?
Free spreadsheet templates paired with manual pitch multipliers cost nothing but take longer and carry higher error risk. Among dedicated roof tools, Roofr's free Starter plan, with measurement reports at about $19 each, is the lowest-cost option.
Can GCs use general construction takeoff software for roofing?
Yes, and for multi-trade GCs it's often the better choice. Tools built for full project takeoff — STACK, Struvia, PlanSwift — handle roof scope alongside framing, siding, and other trades instead of forcing you into a separate roofing-only app.
How do you compare roofing sub bids properly?
Build your own quantity takeoff first, then line up every sub bid against that baseline rather than against each other. Scope gaps — missing flashing, insulation, or warranty tiers — usually explain price spreads better than actual pricing differences do.
Does STACK do roofing takeoffs?
Yes. STACK supports pitch calculation, waste factor, and material takeoff for roofing alongside other trade scopes in the same project file, making it a solid fit for GCs who don't want a separate roofing-only tool.
Roof scopes don't belong in a standalone app disconnected from the rest of your bid — they belong inside the same workflow where you're comparing every sub's numbers against your own. Upload a plan set free and run the roof takeoff and your roofing sub bid leveling in one place, or book a demo and walk through a live roof scope with the team.
