The National Weather Service in Phoenix named Scottsdale in two flash flood warnings on Friday, Oct. 30, 2026. The first, issued at 5:49 p.m. MST, listed Scottsdale, Cave Creek, Carefree, Desert Mountain and Scottsdale Airport. The second, at 6:11 p.m., listed Scottsdale, Paradise Valley and Scottsdale Airport. On Sunday, Nov. 1, flood warnings issued at 3:30 p.m. and 9:01 p.m. described continued flow through Indian Bend Wash and flooded low-water crossings.
What the record shows, and what it does not
An NWS storm report logged for about 1:00 p.m. on Nov. 1 said roads around El Dorado Park were closed by flooding from Indian Bend Wash (NWS local storm reports). It was a delayed report, so the closure may have started earlier. These are ground-water events: washes, streets and low crossings. None of the warnings or reports says a roof was damaged.
Roof, wall or ground: how to tell
If water got into your house, where it showed up is the first clue. None of this is a diagnosis, but it helps you describe the problem to whoever you call.
- Ceiling stains or drips, especially below valleys, skylights, vents, chimneys, or where a flat roof meets a wall, often point to the roof.
- Water along the bottom of exterior walls, on garage floors or in low rooms often points to ground drainage rather than the roof.
- Dampness high on an exterior wall or around a window can come from wall flashing, stucco or the window itself, not only the roof.
- Timing helps. A stain that appeared during the heaviest rain is a different clue from one that has been slowly growing for weeks.
Trace the edge of any ceiling stain in pencil and write the date beside it, so you can tell whether it is growing. Photograph it in daylight. Stay off the roof, since wet tile and foam are slippery and tile can crack underfoot. If water is coming in, protect belongings and call for help.
Where this fits with earlier storms
Scottsdale was also named in an Oct. 22 flood advisory, which we covered in our post on what a soaking rain tells you about your roof. For drainage problems that show up at the roof edge and in the yard, see our North Scottsdale roof-drainage check. A roof that has been rained on three times in two weeks is worth a look even if nothing has leaked yet.
Apex Roofing Systems offers a free roof inspection for Scottsdale homes. We photograph what we find, and we will tell you plainly if the roof is not the source. Call (480) 808-ROOF (7663).
