How We Built Roof360 to Improve Property Listing Accuracy in the Dominican Republic
TechnBrains developed Roof360, a real estate marketplace connecting property owners, agents, buyers, and renters across the Dominican Republic. The platform combines verified property listings, duplicate-submission controls, agent authorization, and map-based discovery across web and mobile, helping users find properties while giving administrators control over listing quality.

About Roof360
A Property Marketplace Where Listings Need More Than Visibility
Roof360 is a real estate marketplace connecting property owners, agents, buyers, and renters across the Dominican Republic. Users can explore properties for sale or rent through interactive maps, advanced filters, and detailed property listings.
The platform allows owners and agents to publish properties, manage listings, and generate buyer inquiries. Paid subscription plans support agent publishing, while buyers and renters can search for properties free of charge.
-
Duplicate listing detection to identify repeated submissions from different agents.
-
Agent authorization checks supported by ownership and exclusivity documents.
-
Paid agent subscriptions with listing limits and sub-agent permissions.
-
Interactive property maps with location filters and buyer inquiry options.
As more agents joined Roof360, managing duplicate property submissions and verifying listing authorization became increasingly important. We wanted a system that could handle multiple agents representing the same property, maintain accurate listings, and give our team better control over what gets published.

Problem
The Challenge
Managing Duplicate Listings and Agent Verification Across the Marketplace
Roof360 needed to manage property submissions from multiple agents without compromising listing accuracy or buyer trust. The challenge was distinguishing legitimate property representations from duplicate or unauthorized submissions while supporting agent growth.
Key Challenges
- 01
Multiple agents submitted the same properties with conflicting listing information.
- 02
Property submissions lacked consistent checks for ownership and agent authorization.
- 03
Duplicate property listings increased administrative review and verification workloads significantly.
- 04
Agent subscription plans required clear publishing limits and account controls.
- 05
Owners and sub-agents needed separate permissions for managing property listings.
- 06
Map and list searches needed consistent property availability and filtering.
Roof360 required a real estate marketplace with reliable listing verification, agent authorization, and duplicate detection to maintain property listing accuracy, reduce misleading submissions, and build trust among buyers, renters, and property owners.
Solution
Our Solution
From Uncontrolled Property Submissions to a Verified Listing Marketplace
TechnBrains built Roof360 as a connected real estate platform across mobile applications, web applications, a public website, and an administrative panel. The solution combines property discovery with submission controls, verification workflows, and publishing permissions.
Duplicate Listing Detection & Review
Roof360 checks incoming property submissions for potential duplicates or repeat entries, allowing administrators to review cases where a property may already exist on the platform.
Less repetitive listing review and better control over duplicate inventory.
Agent Authorization & Property Verification
When an agent submits a property already represented in the marketplace, authorization or exclusivity documentation can support the review of their right to advertise it.
Multiple-agent participation without treating every repeated property submission as automatically legitimate.
Role-Based Owner, Agent & Sub-Agent Accounts
The platform supports separate account responsibilities for property owners, agents, and sub-agents. Authorized sub-agents can create property listings on an agent's behalf.
Delegated listing management with clearer responsibility for property submissions.
Subscription Plans & Listing Limits
Paid agent plans control property publishing and listing allowances, while browsing remains free for buyers and renters.
A subscription-based marketplace model with controlled inventory publishing.
Interactive Map & Filtered Property Search
Buyers can explore properties across the Dominican Republic using location-based maps and filters for property type, price, and other relevant details. Sale and rental listings are visually distinguished, with black markers for properties for sale and gold markers for rentals.
Consistent property discovery through synchronized map and list views.
Listing Visibility & Lead Generation
Property profiles display relevant details and connect interested buyers or renters with owners and agents. Publishing tools help agents present their inventory to prospective customers.
A direct property discovery and inquiry channel for participating real estate professionals.
Engineering Approach
Separating Property Identity From Agent Publishing Rights
A basic listing marketplace assumes each submitted listing represents a new property. Roof360 needed different logic because several agents could legitimately advertise the same apartment or commercial space.
TechnBrains structured the platform around property-level duplicate checks, agent-specific authorization, and controlled publishing permissions. Repeat submissions could be reviewed against existing inventory, with supporting documents available where authorization needed to be established.
The team also connected subscription-based listing limits, delegated sub-agent workflows, and synchronized map/list discovery across web and mobile. These decisions allowed Roof360 to expand agent participation without making listing volume the only measure of marketplace growth.
Impact
The Impact
From Repeated Property Submissions to Controlled Marketplace Inventory
Roof360 introduced verification and publishing controls alongside buyer-facing property discovery.
| Before | After |
|---|---|
| Multiple submissions for the same property | Duplicate detection and review workflow |
| Unclear rights to advertise existing properties | Agent authorization documentation |
| Unrestricted listing submissions | Paid plans with publishing limits |
| Agents needing assistance managing inventory | Delegated sub-agent listing creation |
| Fragmented map and listing results | Synchronized map-based and filtered discovery |
| Limited buyer confidence in property information | Property details, listing review, and reporting capabilities |
Our Engagement
Business Outcomes
Engineering the Complete Marketplace, Not Just the Property Search App
TechnBrains developed Roof360 across four connected product surfaces: the mobile application, web application, public website, and administrative panel.
The engineering scope extended beyond property search interfaces to the operational rules governing listing publication, verification, subscription limits, and agent authorization.
The project required balancing competing marketplace needs. Agents needed flexibility to advertise inventory and delegate publishing, while the platform needed safeguards against duplicate submissions and unsupported property claims.
Roof360 demonstrates TechnBrains' experience in real estate marketplace development where marketplace growth, property credibility, and commercial publishing rules must work together.
- 912Property Listings
- 414Real Estate Agents Onboarded
- 59 Property Owners
- 1,000+ Google Play Store Downloads
- 20–30% Estimated Reduction in Duplicate-Listing Review Effort
When two agents submit the same apartment, the platform needs to determine whether both are authorized to advertise it. Rejecting the second submission could prevent a legitimate agent from listing the property, while approving it automatically could create duplicate listings and confuse buyers. We addressed this by connecting duplicate detection with agent authorization, allowing the platform to evaluate each submission before publication.
