Water coming through the ceiling during a storm is the one foam-roof problem that can't wait for April. Here is what to do in the first hour, and a number that is answered.
After any event above: look for ponding past 48 hours, new blisters, and drips at scuppers. Read the October 2026 storm review or get an emergency leak repair.
Single pinhole or bird hole, blister split, seam at a parapet, coating intact elsewhere. Elastomeric patch and a spot coat holds through the season.
Saturated foam over a wide area, multiple leaks, or heavy chalking everywhere. A temporary dry-in now, then a cut-out and recoat once the roof is dry — coating a wet roof traps the water.
Updated after each significant event (NWS Phoenix). The monsoon season runs June 15 – September 30; the off-season cut-off lows below are why a foam roof is checked after October rain too. Sky Harbor's wettest monsoon on record was 9.56 in (1984); the driest was 0.15 in (2023). Full write-ups on the storm watch page.
Outflow winds ahead of a storm drive rain horizontally and lift coating edges at parapets; haboob dust fills scuppers so the next rain ponds; hail bruises a chalked coat. None of it is unusual, and none of it is a reason to replace the roof. The monsoon leak guide →
Most foam roofers run extended hours in storm weeks rather than true 24-hour dispatch. Our partner extends to 7am–8pm during monsoon and answers within four rings; night calls go to voicemail and are returned first thing.
Sudden storm damage (wind, hail) is typically covered; wear — a chalked coating that was overdue — typically is not. Photos before and after, and the roofer's written cause-of-leak, decide it.
No. Coating over saturated foam seals the water in. The roof must be dried (or the wet foam cut out) first — which is why a dry-in and a scheduled repair is sometimes the honest answer.
