Roof Drain Testing procedure

  1. Drain bladders are placed as stoppers at the foot of all the downspouts for the home.
  2. The roofing contractor, under the supervision of Stonemark’s construction manager, fills the drain lines with water from the roof level. Another contractor will be present inside the home at all times during the test.
  3. The water is allowed to sit in the drain for about an hour to test for pinhole leaks and incipient failures.
  4. If there is no evidence of leakage i.e., staining or wet drywall, the water is released. Homeowners can then have some degree of confidence in the integrity of the existing drain pipes.

Roof Drain Testing is performed again at the end of the re-roofing to confirm that the joint at the roof level has been properly executed. You will receive another Notice when this procedure is scheduled to be performed.
