Some areas of my granule surfaced rolled roofing on my home addition are more worn out than others. It is almost down to the asphalt base in these areas but it is about 10% of the entire area and it is because of a gutter leak from a shingled roof above that is now repaired. This roof is not leaking yet and I want to do preventive repair.
I am not sure what to do. These is something called quick roof
that is aluminized and has several layers and is stuck by removing the release paper. There are some elastomeric coatings such as Kool Seal
and Snow roof
The elastomeric coatings also need primer.
Any suggestions anyone. The roof is sloping but the drop is about 1 in 10
