Allow the patch to dry completely before applying a reflective coating or roof sealant.

- New roofing material (membrane, EPDM, PVC, TPO, or bitumen)
- Adhesive (roofing cement or rubber sealant)
- Scissors or utility knife
- Wire brush or sandpaper
- Paintbrush or roller
First, remove the damaged section of roofing material with a utility knife or scissors.

To ensure proper drainage and prevent future leaks on your flat roof, you can do the following:
