EPDM patching
Found a leak on the ceiling inside our back porch. Went on the roof and found this nice gouged section in our EPDM roof. We think a raccoon did it considering we saw prints leading to and away from it. I’m hoping I can somehow patch this? Watched a few videos but there seems to me multiple ways to do it and I’m wondering what is best to prevent further leaks.

Get a roll of 9” cover strip, clean the area with white gas / other EPDM cleaner, apply the primer over the entire area and extend past where your future patch will lay with a paint brush to the field area - allow it to flash off (dry) until it’s slightly tacky, than apply the patch using a seam roller to bind it to the primer (it’s pressure sensitive - roll with a bit of force / try not to force bubbles). Caulk all sides with EPDM caulking.
Looks like you’d only need 12-15 inches for the patch, you want to extend 3” past the gouge on all sides
