Understanding risks in the roof during construction

The roof during construction

Roofs during the construction phase: water and risks under control

During the construction phase, the roof is often not yet completely waterproof, materials are stored temporarily, and the load changes continuously. Inscio shows how water, moisture, and temperature behave on and inside the roof, so that risks remain manageable before leaks or other damage occur.

Why roofs are so vulnerable during the construction phase

During the construction phase, the roof is not a quiet, isolated part of the building, but a dynamic work site:

  • the roofing is temporary or has not yet been fully installed
  • rainwater drains have not yet been permanently connected or have been (partially) closed off
  • material is stored on the roof
  • ballast or installations are temporarily positioned differently than in the design
  • construction logistics causes varying concentrated loads

Combined with rain, wind, and temperature differences, this leads to risks of water accumulation, moisture in the roof structure, and leaks. Without insight into what is happening on the roof, these risks remain invisible until something goes wrong.

What does Inscio measure?

What Inscio measures on and in the roof during the construction phase

Moisture in the roof structure

  • moisture accumulation in insulation and underlayments
  • effect of temporary leaks or damaged roofing

Temperature and dew point

  • temperature differences across the roof surface
  • risk of condensation in the roof structure
  • link between outdoor climate and indoor conditions

Critical details and implementation

  • areas around rainwater drains
  • connections between upstands, roof edges, and skylights
  • implementation for installations (temporary and permanent)
Typical risks on roofs during the construction phase

Inscio observes that the same patterns recur regularly in construction projects:

  • Water that remains standing due to temporary blockages or lack of drainage
  • Roofing that is not (yet) completely waterproof, with moisture seeping into the structure
  • temporary storage of materials (pallets, insulation, installations) that causes extra load and deflection
  • damage to vapor barriers and details that lead to condensation and leaks at a later stage
  • insufficient insight into the combinations of rain, snow, and construction phasing, resulting in the roof having to bear more weight than anticipated
  • Many of these risks are visible early on in data, but much less so with the naked eye or an occasional inspection.

What Inscio adds to the construction site

Sensors continuously record water level, moisture, and temperature. The behavior of the roof becomes visible, even when no one is standing on it.

The software recognizes abnormal behavior, such as rising water levels or moisture buildup, and sends notifications as soon as threshold values are exceeded.

Instead of relying on gut feeling, decisions are made based on when intervention is needed: additional emergency drainage, relocation of storage, repair of details, or accelerated finishing.

You use data to demonstrate that you have actively and promptly addressed risks.

Our customers tell their stories

"Thanks to Inscio's sensors, we can clearly see how much moisture the wood is exposed to during the construction period."

Taco Valstar – ERA Contour

 Until last fall, we informed clients and partners about expected roof behavior based on practical experience. Now we provide objective measurement data.

"We believe that things can and must be done differently."

Imagine this: you take your car to the garage for maintenance. The mechanic stares at the shiny paintwork with a concerned look, runs his hands over the surface, and takes some photos. Then he comes back excitedly and concludes that the engine is broken and needs to be replaced.  

That sounds absurd, doesn't it? And yet that is roughly what happens during real estate inspections. We believe that things can and must be done differently.
