How to Prepare a Commercial Roof for San Diego's Rainy Season

Why fall matters

San Diego gets most of its rain between November and March. Months of dry weather let debris build up in drains and sealants dry out — then the first storm finds every weak spot.

Fall roof checklist

• Clear all drains, scuppers and gutters
• Remove debris and leaves from the roof field
• Inspect and reseal flashing and pitch pans
• Check HVAC curbs and condensate lines
• Look for ponding areas and soft spots
• Photograph everything for your records

After the first storm

Walk the top floor and look for ceiling stains. Catching a slow leak early prevents insulation and ceiling damage.
