Flat Roof Inspection

The place where we made the hole is right beside the existing PVC membrane we have done. From the edge of the roof to the hole on the roof is 6 feet apart.

These pictures as you can see will be cover with PVC membrane as per manufacturers specifications. The new PVC membrane will overlap and seal together on to the existing PVC membrane.

Flat Roof Inspection

When removing the piece of insulation on the flat roof to do a core test we found that the metal was rusted and corroded. Then we place the piece of insulation back in its spot and put on some asphalt roof mastic on top.
