KattoHoiva (RoofCare) provides roof inspections, roof maintenance and roof repairs to commercial, industrial and residential buildings.

KattoHoiva also provides an new innovative product, Controlit conductive underlays, for flat roofs that are installed under the bitumen or pvc roof membranes to ensure that roofs are waterproof after the installation of the roof and to effectively conduct electronic leak detections and repairs on roofs during the life-cycle of the building.

Closest reference to a data center with Controlit conductive underlays is in Tallinn Estonia, where the owner / user wanted to be 100 % sure that the roof is waterproof. References in Finland for Controlit installations are Technopolis and Vilpe Oy. This new innovation is something that we wish to promote and inform about in addition to our other services.
