Sense Smart Roofs Let's talk

Two sensors and one platform for flat and low-slope roofs

One system for the roofs of large buildings. S-One measures how the roof structure deflects under snow and rain load, DSW measures ponding water at the drains, and the Smart Roofs Platform turns both into alerts for your team.

What each part does

  • S-One sensor on a steel bracket at a roof support inside a warehouse, status light on

    S-One

    Measures how much your roof structure deflects under snow and rain load, around the clock.

  • DSW sensor with a small solar panel on a concrete ballast block, next to a roof drain on a flat roof

    DSW

    Measures ponding water next to your roof drains, every minute, so you know when a drain stops keeping up.

    Smart Roofs Platform

    One place for every roof you manage, with live readings, alerts and weather warnings.

Weather Alerts

The platform compares 48-hour and 7-day forecasts from OpenWeather, which covers locations across the United States, with the design parameters of your building. If it sees a risk, you get an alert in advance, with tips on how to protect the roof. It works without any sensors on the roof.

How the system fits together

From the roof to your team's phones in four steps, on every building you manage.

  1. Step 1

    Sensors measure the roof

    S-One measures deflection every 3 minutes. DSW measures the water at the drains every 60 seconds.

  2. Step 2

    A gateway on site collects the readings

    S-One sends over a self-healing wireless mesh, DSW over LoRaWAN. The DSW gateway connects through its own cellular modem, not the building's network.

  3. Step 3

    The platform checks every reading

    The Smart Roofs Platform analyzes the readings 24/7 against the thresholds set for each measuring point, and adds weather forecasts.

  4. Step 4

    Your team gets the alert

    SMS, email and app notifications when a threshold is crossed, and a history of every snowfall and rainstorm.

Backed by structural engineers

Sense has its own structural engineers, and its CCO and co-founder is a civil engineer licensed in Poland.

  • Sensor layout from the structural design

    Our engineers analyze the structural design documentation and decide how many sensors a roof needs and where they go.

  • Thresholds from the allowable deflection

    Alert levels come from the allowable deflection in the building's design, confirmed with its designer. Without documentation, a structural assessment comes first.

  • Engineering experience behind the monitoring

    In Europe, the same team prepares snow-removal plans, roof load-capacity assessments and drainage audits.
