roofSec is the world’s first fully automated monitoring and leak detection system for flat roofs. Sensor cable technology combined with AI-powered cloud analysis detects moisture in real-time — before it causes costly damage.
The Problem
Flat roofs are increasingly topped with green roofing, PV systems, or walkable terraces. The waterproofing membrane becomes invisible and inaccessible. When a leak occurs, it goes undetected for months — until stains, mould, or structural damage appear. A single undetected leak can cause €50,000 to €200,000 in damage.
How It Works — 3 Steps
1. Sensor Cable
Installed on the vapour barrier in a pre-planned pattern. Up to 100 sensors per cable, each uniquely identifiable — pinpointing leaks to the nearest metre.
2. Communication Unit
Mounted inside the building. Queries all sensors at regular intervals and transmits data to the cloud. Supports up to 4 cables (~500 m²).
3. Cloud & AI
Intelligent algorithms analyse sensor data 24/7. If moisture is detected, the owner receives an instant email alert with the exact leak location on a roof plan.

Key Advantages
- Precise localisation — to the nearest metre
- 24/7 automated monitoring — no inspections needed
- Works under any roof type — green, PV, terrace, ballast
- All standard materials — bitumen, PVC, EPDM, TPO
- Free cloud service — no subscriptions, ever
- Maintenance-free — built for 25–40 years

Where to Buy
Available through specialised distributors in Austria: Austrodach and FLATTEC. Professional installation by certified roofers recommended. For other regions, contact us.
Use Cases
Green Roofs
Substrate and vegetation make visual inspection impossible. roofSec monitors continuously beneath the layers.
PV Installations
Solar panel mounting creates potential weak points. Monitoring detects damage before it spreads.
Walkable Terraces
Pavers and pedestals cover the membrane. Leaks go unnoticed for years without monitoring.
Inverted Roofs
Insulation above the membrane — traditional inspection from above is meaningless.

Installation Requirements
roofSec is installed during new construction or full roof renovation. Retrofitting requires removing existing roof layers. What you need:
- Conduit from roof to communication unit
- Power supply (see datasheet)
- Internet connection (LAN or WiFi)
- Vapour-tight conduit connection
- Tape for cable fixing at corners
- Current email address for alerts
About roofSec GmbH

FAQ
Can roofSec be retrofitted?
Only during a full roof renovation, as the sensor cable must be placed on the vapour barrier beneath all other layers.
What happens when a leak is detected?
The cloud service sends an automatic email alert with the approximate leak location on a roof plan — enabling targeted repair without unnecessary demolition.
Are there recurring costs?
No. One-time purchase, free cloud service for life. No subscriptions, no annual fees.
How long does the system last?
25–40 years (full roof lifetime). No moving parts, no maintenance. Software updates are server-side and automatic.
How much does it cost?
Depends on roof size, shape, and penetrations. Use our planning tool for an exact quote. Contact us for a consultation.
Does it replace maintenance contracts?
roofSec is an early warning system. We still recommend regular roof maintenance for drain cleaning and material inspections.
What about data privacy?
Personal data is never shared with third parties. Used solely for damage notifications. Full GDPR compliance.
