Monsoon Roof Checklist for Glendale Homes

Arizona's monsoon season runs from June 15 to September 30. Storms can bring dust, wind and heavy rain in the same hour. A little preparation keeps most of that water outside.

Tile roofs and underlayment

Most Glendale roofs are concrete or clay tile. The tiles last decades, but the underlayment beneath them wears out in the heat, often after 20 to 30 years. Many 1980s and 90s roofs are reaching that age.

Cracked and slipped tiles

Look from the ground or with binoculars for cracked, slipped or missing tiles. Each one exposes underlayment to sun and rain.

Valleys and gutters

Debris collects in roof valleys and gutters, especially after dust storms. Water backs up under tiles. Clear them before and during the season.

Flashing and penetrations

Vents, skylights, solar mounts and walls where the roof meets them need sound flashing. Ask a roofer to check them.

Before June 15

  • Roof inspection
  • Clear valleys and gutters
  • Clean slider weep holes
  • Check door thresholds
  • Note ceiling stains

Flat sections

Patios and additions often have flat roof sections that drain through scuppers. Clear them and look for cracks.

Sliders and windows

Clean slider tracks and weep holes so water can drain out instead of backing up inside. Check window seals.

Doors and grading

Make sure soil slopes away from the house and doors have good sweeps and thresholds. Keep sandbags if water has entered before.

Inside

Note existing ceiling stains so you can tell if a new one appears. Keep buckets, towels and a flashlight ready.

During a storm

Close windows, move patio items that could blow into glass and stay off the roof. Put buckets under drips and protect belongings.

After a storm

Walk around the house, check ceilings and photograph any damage with the date. Call a roofer for the roof and a restoration provider for the inside.

Roof replacement vs lift and relay

If underlayment is worn but tiles are good, a lift and relay replaces the underlayment and reuses the tiles, often for much less than a new roof. Check roofers with the Arizona ROC license lookup.

Why storms find old underlayment

Monsoon storms often arrive with strong wind that drives rain sideways under tile laps. On a newer roof, the underlayment beneath catches that water and sheds it. On a roof with 25 or 30 year old underlayment, cracks and tears let the water reach the roof deck and drip into the attic. That is why ceiling stains often show up in the second or third big storm of a season, as worn spots finally give way.

Solar panels and roof mounts

Many Glendale homes have rooftop solar. The mounts penetrate the roof, and poor flashing around them can leak. If a stain appears after solar was installed or serviced, ask the installer to check the mounts. Also ask anyone working on the roof to walk only where the tiles can take the weight, since cracked tiles are a common source of leaks.

Dust storms first

Monsoon storms often begin with a dust storm that fills valleys, gutters and slider tracks with dirt. Then the rain comes and has nowhere to drain. Clearing debris after a dust storm and before the next rain reduces leaks at both the roof and the doors.

Lift and relay

When underlayment is worn but tiles are in good shape, roofers remove the tiles, install new underlayment and battens, and put the tiles back, replacing broken ones. It costs much less than a new roof and can add many dry years. Ask for photos of the old underlayment so you can see why the work is needed.

Documenting storm damage

Photograph damaged tiles from the ground, ceiling stains and any water inside, with the date. Note when the storm hit. A roofer's written report on the cause helps insurance decide whether the damage is sudden storm damage or wear.

Help after a storm

Ceiling stain after a storm? Catch the water and call (623) 624-9995 for a local provider.

Inside prep

Keep buckets, towels, a tarp and a flashlight where you can find them. Know which breaker controls each room's lights. Save (623) 624-9995 in your phone so help is one call away during a storm.

Insurance

Sudden storm damage, such as wind lifting tiles, is often covered. Leaks from worn-out underlayment may be treated as wear and tear. A roofer's written note on the cause helps.

Last word

Most storm leaks start with a roof or door that was due for attention. Check before June 15 and the storms stay outside.
