As we soak up the last of summer in Southern California, it’s easy to put off roof concerns until the first drop of rain hits. But waiting until then is often too late. At Adco South Roofing, we’re already seeing signs of wear and tear on commercial roofs across Orange County – and now is the best time to act.
Here are the top 5 signs your commercial or multi-unit roof may need attention before fall weather moves in:
1. Ponding Water That Won’t Go Away
Even during dry months, leftover ponding from early summer storms or HVAC condensation is a red flag. Standing water breaks down membranes, adds weight, and attracts debris—leading to leaks over time.
Fix it before: moisture seeps through seams or decking once cooler weather arrives.
2. Cracked or Deteriorated Flashings
Flashings are the unsung heroes of any roof system. When they crack, pull away, or dry out from UV exposure, water intrusion is almost guaranteed.
If your building has aged metal flashings, now is the time to check their condition.
3. Blistering or Bubbles on the Surface
Blisters in flat roof membranes are caused by trapped moisture or air. Left untreated, they can pop or split open—especially after heavy rains—and expose the layers below to damage.
These are easy for our team to spot during a summer inspection.
4. Debris, Clogged Drains, and Overgrown Rooflines
Leaves, palm fronds, and trash collect quickly in OC, especially around drains, scuppers, and behind HVAC units. If water has nowhere to go, it will find its way inside.
Clearing these areas is one of the easiest ways to prevent a preventable leak.
5. Signs of Interior Damage or Ceiling Stains
Have tenants noticed brown spots or bubbling paint on ceilings? That’s usually the last (and worst) warning sign. Water may already be breaching the roof, insulation, or drywall—and getting worse each day it’s ignored.
