Monsoon Damage: What Summer Storms Do to Phoenix Roofs and Drainage

The desert tests every home once a year

From late June through September, monsoon storms hit the Valley with wind, dust and sudden inches of rain. Homes that looked flawless in April reveal their weaknesses in August, and inspectors read those revelations all year long.

What monsoons expose on roofs

  • Lifted and slipped tiles: wind works tiles loose and exposes underlayment to direct water
  • Marginal flashings: penetrations and transitions that shed light rain but fail in wind-driven storms
  • Debris dams: valleys and scuppers packed with leaves that reroute water under the covering
  • Aged shingles: brittle edges that wind peels a little further each storm

What monsoons expose on the ground

Grading is destiny in a storm. Soil that slopes toward the foundation, low spots against stem walls and short downspouts all send water where it does damage: staining stem walls, wicking into interiors and settling slabs. During inspections we evaluate where a storms water will actually go, because in August it will go there fast.

Buying during monsoon season?

A storm-season inspection is an advantage: recent weather makes leaks and drainage failures visible in ways a dry March cannot. Interior ceiling stains, fresh efflorescence and damp stem walls all speak clearly after rain.
