A newer innovation for metal roof replacement is the metal roof retrofit method. This method allows for a single ply roofing system to be installed directly over the existing metal roof system where the metal roof then becomes the roof deck.
The area between the metal panel ribs is filled in with insulation board. This creates a flush surface. After the infill is installed an additional layer of insulation board is installed creating a solid surface to apply the roof membrane to. Finally a new single ply membrane is installed.
One of the best solutions is OMG’s RhinoBond System. RhinoBond is an alternative membrane attachment system for TPO and PVC roofing membranes and ideal for the metal retrofit method. OMG’s RhinoBond metal retrofit method is an approved Factory Mutual system and secure the membrane without penetration.
