💧 1. Ponding Water — The Most Common Flat Roof Problem

Flat roofs aren’t truly flat; they’re designed with a slight slope to allow water to drain. But over time, drainage systems can clog or sagging can occur, causing water to pool.
If water sits for more than 48 hours, it can weaken materials and eventually cause leaks.

Solution: Routine inspections and cleaning keep drains clear. In some cases, re-leveling or adding tapered insulation can permanently fix drainage issues.

🧱 2. Cracks, Blisters, or Surface Damage

UV rays, temperature changes, and foot traffic can cause blisters, cracks, and splits in flat roofing membranes. Left untreated, these allow water to seep in and cause interior damage.

Solution: Professional roofers can patch or recoat damaged areas before they spread. Caruzo’s Roofing offers preventive maintenance and coating systems to extend your roof’s life and performance.

🌿 3. Clogged Drains and Gutters

Leaves, dirt, and debris easily collect on flat roofs — especially after windy or rainy weather. Blocked drains cause ponding water and speed up deterioration.

Solution: Schedule seasonal maintenance to clear debris and inspect drain lines. A clean roof surface helps prevent leaks and keeps your warranty valid.

⚡ 4. Poor Installation or Aging Materials

Many roof leaks start with improper installation or old roofing materials that have simply reached the end of their lifespan. A poorly installed roof might look fine for years before suddenly failing during a storm.

Solution: If your flat roof is over 15–20 years old, or if you notice frequent leaks, it may be time for a full roof replacement. Our team installs durable, energy-efficient flat roofing systems built to handle Bay Area conditions.

🔧 5. Regular Maintenance Keeps Your Roof Strong

Commercial flat roofs perform best with consistent inspections. We recommend semi-annual checkups — once before the rainy season and once after — to catch early signs of wear, clear drains, and repair minor issues before they turn major.

At Caruzo’s Roofing, we make commercial maintenance easy. We work around your schedule to ensure minimal disruption to your business or tenants, and we provide detailed reports with every inspection.
