Hi I have a small hole about 4 inches x 2 inches in my lean to conservatory roof (reinforced polycarb type) It is a neat rectangle in the direction of the slope without crossing the metal reinforcing bars. This was damage by a contractor working on the roof on the window above. He realised what he had done and sqaured out the whole but never returned to repair it and has now disappeared.
The hole does not let in the rain as it is close to the house wall. Only the out layer is holed but it is starting to fill with loose debris.
Can anyone suggest a way to repair or is it to be a whole new roof ?
Cheers
Chris
