Monsoon Season Flat Roof Checklist

July and August storms dump a lot of water in a short time. A spring check catches most problems before they become leaks.

Before the storms (May–June)

  • Clear every canale and scupper of leaves, nests and dirt
  • Check that canales slope out and are firmly attached
  • Look for cracked parapet caps and split inside corners
  • Check coating: chalky, cracked, blistered, or foam showing?
  • Look at seals around skylights, vents and cooler stands
  • Note any low spots with dirt rings from last year's ponding
  • Trim branches that drop debris on the roof

During monsoon

  • Watch where water leaves the roof during a storm — it should shoot clear of the walls
  • Check ceilings after big storms, especially near exterior walls
  • Clear canales again after windy storms

After a big storm

  • Look for hail marks or fractured coating
  • Check for standing water still there a day later
  • Note any new stains inside, with the date

If hail hit hard, document it with photos and call for an inspection. Your insurer decides coverage.

When to call

Any of these before July: foam showing, cracked parapets, a canale tipping back, or last year's leak "patched" but never fixed. Coating and parapet work books up before monsoon, so call early. See the best time to coat.

Common questions

Is it safe to clean canales myself?

From a stable ladder, often yes. Avoid walking near parapet edges, and skip it on wet or windy days.

My roof ponds after every storm. Is that normal?

A little water that's gone in a day is common. Water that stays longer should be fixed.
