Will rubba-roof pro™ repair holes in rigid sheet roofing?
Holes and cracks in sheet roofing cannot easily be repaired with mastic material, as the sheet has no appreciable thickness in which to provide a key. Damage should therefore be over-banded as described above. When a hole is being patched with scrim, the overlap must be large enough to prevent the impregnation scrim sagging. Large holes in sheet roofing will necessitate replacement of the whole sheet.
