Method of securing multiple layered roof structures

DETAILED DESCRIPTION The present invention deals with solutions to the problems of securing a roof in place and the inability to quickly and accurately determine the location of roof leaks.
The instant invention therefore comprises a hold down device, a modified hold down device for use in detecting water leaks in a roof, and a method of securing a roof in place as well as a method for detecting leaks in a roof.
Thus, the present invention deals with a hold down device consisting of two joinable pieces.
The device is designed such that the bottom half of the device is securely attached to a roof deck over the water-impermeable membrane and after the multiple layers of the roof are installed, the top half of the device is operably joined with the bottom half and tightened down such that the top plate of the top half compresses the top layer of the multiple layer roof and holds the top layer and all intervening layers to the roof deck.
The result is a novel hold down device which has penetrated through but has not destroyed the water-impermeable membrane and has provided secure anchoring for the roof layers.
This device can be modified in order to enable the easy detection of roof leaks.
This is accomplished by providing electrical leads in the bottom plate where it is anchored to the roof deck.
The leads pierce the water-impermeable membrane and enter the roof deck but the bottom plate is compressed over the penetrations made by the leads and acts as a seal on the penetrations when the plate is securely fastened to the roof deck.
The electrical leads are continued through the internal stems of the device and terminate in electrical contact points.
The top half of the device is similarly constructed so that the two halves, when joined, provide electrical contact points at the upper surface of the roof that can be used to ascertain water leakage in the roof.
When such devices are used in combination to secure a roof, they provide a regularly spaced layout of such devices that one can use to determine the exact location of a water leak in the roof
