Accurate roofing estimates are essential for protecting your profit margins. If you’re bidding on a residential shingle roof or a commercial flat roof system, you need precise quantities for every component. Our roofing estimating services help contractors to eliminate waste, and submit winning bids. ALM estimating delivers fast and reliable roof estimates via industry-leading software. Our experienced estimators understand roofing inside and out.ow many feet of 2-inch PVC you will need. Did you count all the fittings? What about those extra cleanouts the engineer added on page six? That is where ALM estimating comes in. Our plumbing estimating services give you exact numbers. Pipe lengths. Fitting counts. Every sink, toilet, and floor drain. Water supply. Drainage. Vent systems. We measure it all so you can bid fast and bid right. No more material shortages. No more over-ordering.

A successful roofing project starts with a logical estimate. Many contractors lose money because of inaccurate material counts or underestimated labor requirements. Our roof takeoff services deliver detailed, accurate quantities tailored to your specific roofing system.
We serve roofing contractors, general contractors, and developers across the United States. Our shingle estimating services cover everything from basic asphalt shingles to high-end tile and metal panel systems.
Our team has experience estimating all common roofing types for both residential and commercial properties.
Home builders and residential contractors need to bid on asphalt shingle roofs, tile roofs, wood shake roofs, and metal roofing. Our estimates account for the unique challenges of residential work.
Commercial projects require specialized knowledge of flat roof systems. We estimate TPO, EPDM, PVC, modified bitumen, and built-up roofing (BUR). Our commercial roofing estimates include insulation, membrane quantities, flashing, and all accessories.
Both replacement projects and new construction require different estimating approaches. We tailor every estimate to your specific project type, accounting for tear-off and disposal when needed.
Large-scale industrial facilities present unique estimating challenges. We handle complex roof geometries, multiple material types, and large square footage with confidence.
Most roofing contractors understand the importance of accurate estimates. But many still struggle with material waste and project delays. Here’s why precision matters for your business.
Ordering too much material ties up cash and cuts into profit. Industry data shows that U.S. roofers lose about 12% of material cost to over-ordering and scrap. Our estimates help you order the right quantities the first time.
Running out of material mid-job creates costly delays and can damage client relationships. We build in appropriate waste factors based on roof complexity so you never come up short.
When you know exactly what you need, you can shop smarter, negotiate better prices, and allocate resources more effectively.
Detailed, credible estimates help you win more jobs. Contractors who use professional takeoff services can deliver estimates up to four times faster and with fewer material-related errors.
The proper waste factor typically ranges from 5% to 15%, depending on roof complexity. Simple gable roofs require only 5–8% waste. While steep or multi-valley designs may need up to 20%. We apply the right percentage for every roof.
Every estimate we deliver is built on precise measurements and industry-standard calculations. Here’s exactly what you’ll receive:
We measure every roof plane, account for slope and overhangs, and calculate total surface area in squares.
Bundle counts based on the manufacturer’s coverage per bundle, plus the appropriate waste factor.
Panel counts for standing seam or exposed fastener systems, including ridge and eave trim.
Square footage of underlayment with overlap allowances factored in.
Board feet or panel counts for commercial flat roof insulation systems.
Crew hours and labor costs based on roof complexity, material type, and project location.
Nail counts, screws, sealants, and other small components.
Linear feet of drip edge, ridge cap, valley flashing, step flashing, and rake trim.
We follow a proven four-step process to deliver accurate, actionable estimates for every client.
You send us your roof plans, digital drawings, or site measurements. Our estimators review the scope of work and identify all components that need quantification.
Using professional takeoff software like PlanSwift and Bluebeam, we measure every roof plane accurately. We account for roof pitch, dormers, valleys, hips, and penetrations.
We calculate exact quantities for every material required: Shingles, tiles, or metal panels, fasteners and sealants etc.
We estimate crew hours based on standard industry production rates. For example, a simple walk-able roof might yield 20 roofing squares per crew day. While a steep or cut-up roof might produce only 8 squares per crew day.
You receive a complete roofing estimate in a clear, easy-to-read format. The report includes material quantities, cost breakdowns, and labor estimates. The estimates are ready to use for bidding or project planning.
To give you a better idea of what we deliver, here is a sample estimate for a typical residential asphalt shingle roof.
Understanding current material costs helps you bid competitively. Here are average roofing costs per square foot for the most common roofing materials.
| Roofing Material | Average Installed Cost Per Square Foot |
|---|---|
| Asphalt Shingles (3-Tab) | $3.50 – $5.00 |
| Architectural Shingles | $5.00 – $8.00 |
| Metal Roofing (Exposed Fastener) | $8.00 – $12.00 |
| Metal Roofing (Standing Seam) | $12.00 – $18.00 |
| Clay or Concrete Tile | $10.00 – $20.00 |
| Wood Shakes or Shingles | $6.00 – $12.00 |
| Flat Roof (TPO, EPDM, PVC) | $4.00 – $10.00 |
| Slate Roofing | $15.00 – $30.00 |
*Costs are based on 2025 U.S. industry averages. Actual pricing varies by location, labor rates, roof complexity, and material availability.
Our roofing estimates serve a variety of construction professionals.
Licensed roofers who need accurate material and labor quantities for bidding or project management.
GCs managing residential or commercial projects that include roofing scopes of work.
Real estate developers planning new construction or renovation projects.
Home builders and construction firms that need reliable roofing estimates for their projects.
Property management companies planning roof repairs or replacements for their buildings.
We start by measuring total roof area in squares (one roofing square equals 100 square feet). From there, we calculate material quantities using manufacturer coverage specifications. For shingles, we divide total area by coverage per bundle. For metal panels, we calculate linear footage based on panel width. We also add a waste factor of 5% to 15% depending on roof complexity.
Yes. We estimate labor costs based on standard industry production rates. Factors like roof pitch, complexity, crew size, and local wage rates are all considered.
We need roof plans, digital drawings, or site measurements. For new construction, blueprints or PDF plans work well. For replacement projects, we can work from rough sketches or satellite measurements. Contact us to discuss your specific needs.
We estimate all common roofing types. For residential projects, we handle asphalt shingles, metal panels, clay and concrete tiles, wood shakes, and slate. For commercial projects, we estimate TPO, EPDM, PVC, modified bitumen, and built-up roofing (BUR). We also handle specialty systems like standing seam metal roofs.
Standard turnaround is 24 to 48 hours from receipt of complete plans. Urgent projects can be expedited upon request.
Our estimates are based on precise digital measurements using PlanSwift and Bluebeam software. We verify every calculation and apply industry-standard waste factors. Contractors who use our estimates report significant reductions in material waste and fewer on-site shortages compared to manual methods.
