Claim One:
1. A method of monitoring moisture in a building comprising: providing a plurality of moisture detectors, each having a detector parameter with a range of values ranging from a dry value in the absence of moisture and different wet values in the presence of moisture depending on the quantity of moisture; dividing the building into a plurality of zones; providing a plurality of sensor units each associated with a respective one of said zones; locating the moisture detectors such that each zone contains at least one of the moisture detectors; connecting each sensor unit to said at least one moisture detector in the respective zone; providing a common monitoring unit for cooperation with a plurality of the sensor units; causing the common monitoring unit to periodically poll each of the sensor units to obtain the value of the detector parameters of the at least one moisture unit connected thereto; and performing a risk assessment calculation of potential damage for at least a part of the building using the wet values from the moisture detectors for the sensor zones in said at least a part; wherein the risk assessment calculation is effected using the different wet values from a plurality of the moisture detectors in conjunction with at least one additional factor indicative of potential damage to the part of the building.
