  1. Safety gear: make sure to be as safe as possible. Make sure to have harnesses or similar incase of a fall. If you don’t feel safe, hire a roofing professional.
  2. Two people: one on the roof one in the attic. Make sure to call each other and communicate.
  3. Water hose: we like using the flex hose for easy storage.
  4. Flashlight: you’ll need this for the person in the attic.
  5. A Ladder: how else are you gonna climb the roof.


Have one person on the roof and the other in the attic or leak location area. Always start at your lowest point when water testing. Run water for 5 minutes till attic person calls out the leak. Turn off the water and begin your plan of action. If you can’t locate the leak call your San Antonio roofing specialist, Rox Roofing.
