Lopez Ramirez Roofing | Roofing Services in Fontana, CA 92335

In Fontana's climate, look for white, chalky deposits (efflorescence), rust streaks, or visible gaps around chimneys, vents, and skylights. You might also notice water stains on interior ceilings or walls near these areas after rain. These are key indicators that the metal flashing, which seals roof transitions, is corroding and needs professional inspection and repair to prevent leaks.

Fontana's temperature fluctuations can cause underlayment—the waterproof barrier beneath your shingles—to become brittle and crack over time. This often happens due to poor attic ventilation trapping heat and moisture. We fix this by first addressing any ventilation issues, then carefully removing the affected shingles to replace the compromised underlayment with a modern, high-performance synthetic underlayment designed for durability in our local conditions.

We recommend a professional inspection at least once a year, ideally in spring or fall, and always after any major weather event. Our local sun, heat, and occasional Santa Ana winds can accelerate wear on materials like flashing and underlayment. A proactive inspection allows us to catch and repair minor issues like small corrosion spots or underlayment tears before they lead to significant water damage inside your home.
