Methodology & Sources

Every number on this site is computed from public, sourced data.

We refuse to put a single dollar figure, percentage, or projection in front of a prospect that we cannot back up. Below is exactly where each figure comes from, refreshed quarterly. If you find a source we should add or a number you'd dispute, write us at hello@agentsundercontract.com.

1. Colorado housing volume per territory

Our 12 Front Range territories are built from US Census ZIP-code population data, residential address counts from USPS, and current sales-volume rates reported by the regional Realtor associations. Each territory's monthly listing volume figure (e.g., Denver Central 300, Colorado Springs 720) is the trailing twelve-month average of MLS-reported under-contract listings, weighted by ZIP population and adjusted down for the share of transactions that close without a listing agent.

2. Inspection-issue incidence (how often inspections flag a roof)

Our default 18 percent slider value for roofing-issue incidence reflects the share of home inspections in mature-housing-stock metros that surface roof material defects, age-related concerns, or condition deficiencies serious enough to warrant repair quotes during the under-contract period. This is on the conservative side of the published band, which runs from 15 to 30 percent depending on housing age and geography. We chose conservative because under-promising on the slider, then letting the customer move it up if their experience says so, is more defensible on the call.

3. Close rates: shared lead vs exclusive lead

The shareFactor in our calculator (0.28 for non-exclusive subscribers, 0.82 for exclusive) is the most important number on the page. It expresses the fact that a listing agent receiving your email alongside four other roofers' emails will close with you a fraction of the time, while a listing agent receiving only your email closes with you most of the time, minus the share she defaults to her pre-existing vendor relationship.

Published industry data on shared-vs-exclusive lead close rates:

We modeled the lift at approximately 3x, sitting comfortably in the middle of the published band and acknowledging that the listing agent's existing vendor relationship typically retains roughly 18 percent of closes even when you're the only roofer on the feed.

4. Real estate agent referral close rates (the upper bound)

Our exclusive close rate ceiling is informed by published data on realtor-to-vendor referrals: when a listing agent personally recommends a contractor to a seller, the close rate runs 50 percent and above. We do not model AUC at that level because most AUC engagements are not personal endorsements, they are warm intros that the agent makes by passing along an email. We sit between cold and personally-vouched.

5. Average closed-job values by trade

The $15,000 default for average closed roofing-job value reflects the median Colorado roof replacement cost in 2025-2026. The slider extends from $5,000 (small repair work) to $60,000 (premium materials, full tear-off, complex roof lines). Customers should set this to their own historical average, which most established roofers know to the dollar. Equivalent ranges for other trades modeled in the spreadsheet:

6. Competitor lead-generation pricing

The cost-per-lead figures used in the comparison panel (HomeAdvisor / Angi Pro Ads at $200 per lead, Google Local Services Ads at $130 per lead for Denver roofing) are pulled from published 2025-2026 industry analyses and customer-reported data. We use Denver-specific rates rather than national averages because per-lead cost varies dramatically by metro, vertical, and job-value richness, and the national-average figures undersell what Front Range roofers actually pay.

Why our LSA figure (130) is higher than the Google marketing-page average (15 to 80):

7. Trade revenue multiplier (40-trade pricing table)

Our pricing across 40 home-service trades scales by a per-trade revenue multiplier ranging from 0.25x (micro-ticket work like handyman jobs) to 2.50x (ultra-premium full-replacement categories like full roof replacement, foundation, major HVAC). The multiplier is derived from three inputs:

The multiplier is intentionally not exposed on customer-facing calculators, because surfacing the lever invites haggling on a number that customers do not have the data to negotiate. Our cost-per-lead bands and exclusivity premiums are end-of-line outputs of the multiplier model.

8. Cold and warm email outreach response rates

For prospects asking about Managed Outreach (we send the emails on your behalf), our reply-rate assumptions sit at 3 to 8 percent for first-touch warm outreach to a listing agent who has just received an under-contract inspection report. This is meaningfully above pure cold B2B email (1 to 5 percent), because the agent has an immediate transactional reason to read the message: she is actively trying to keep the deal together.

9. Multi-territory bulk-discount and exclusivity pricing structure

Our daily-feed pricing of $873 for the first territory and $437 for each additional (a 50 percent bulk discount, the franchise pattern) is consistent with how franchise systems and lead-gen subscription platforms structure multi-territory deals. Exclusivity pricing at $6,250 per first territory and $3,125 per additional reflects the documented practice of charging higher fees for territory-exclusive franchise grants.
