Tempe Roof Leak Repair
We follow the water back to where it got in, then fix that spot instead of smearing sealant around it.
A ceiling stain rarely sits directly under the hole. Water lands on the underlayment, runs downhill along a batten or rafter, and drips somewhere else. That's why so many leak "repairs" don't hold.
We start in the attic when there's access, mark where the decking is stained, and then trace uphill on the roof. On tile roofs we lift tiles around the suspect area. On shingle and foam roofs we check every seam and penetration nearby.
Most Tempe leaks we find come from four places: roof-to-wall flashing, valleys, plumbing vents and the edges of rooftop AC stands. Each one has a proper fix.


Where a roof meets a stucco wall or chimney, old flashing pulls loose and water gets behind it.

Debris dams up the valley and rust opens holes in older metal pans.

Cracked rubber boots and dried-out lead jacks around plumbing vents.

Stained decking in the attic shows how far the water has traveled.
| Situation | What we usually recommend |
|---|---|
| One leak, underlayment still flexible | Repair the flashing or penetration and reset the tiles |
| Repeat leaks in one area | Replace the underlayment in that section |
| Leaks in several areas of a tile roof | Tile underlayment replacement across the roof |
| Shingles brittle and curling everywhere | A new shingle roof rather than another patch |
Wind-driven rain gets pushed sideways under tiles and into flashing laps that stay dry in a gentle shower. Those leaks usually point to a flashing detail or worn underlayment, not a hole you can see.
Usually. Water leaves stains and rot on the decking, and worn flashing is visible once tiles are lifted. We can also water-test a suspected spot with a hose.
Rarely for long. Sealant shrinks and cracks in Tempe's summer heat. We use it only as a secondary seal behind proper metal flashing.
No. Fix the roof first and let the drywall dry out. Then repair the ceiling once you know the leak has stopped.
Tell us where the stain is and when it shows up. We'll trace it to the source and send photos.
