Common Causes of Roof Leaks

Cracked or Broken Roof Tiles: Shifting weather conditions can cause tiles to crack, leading to water ingress.

Damaged Roof Flashing: Poorly sealed or corroded flashing around chimneys, vents, and skylights is a major cause of leaks.

Blocked Gutters: Clogged gutters cause water to back up and penetrate roof structures.

Aging Roof Sarking: Degraded sarking under tiles allows moisture to seep through.

Poor Workmanship: Improper repairs or low-quality materials can lead to recurring leaks.

Our Advanced Roof Leak Detection Process

At Red Leaf Roof & Gutter, we employ cutting-edge leak detection technology to identify even the most elusive roof leaks. Here’s how we do it:

Visual Roof Inspection: We start with a thorough examination of your roof, checking for visible damage, water stains, and weak points.

Moisture Mapping: Using advanced moisture meters, we detect hidden dampness and water ingress behind roof surfaces.

Thermal Imaging: Our thermal cameras identify temperature variations caused by water penetration, allowing us to find leaks that aren’t visible to the naked eye.

Drone Inspections: For hard-to-reach areas, we use drones to capture high-resolution imagery and pinpoint external damage.

Detailed Report & Photos: We provide a comprehensive report with before-and-after photos to give you a clear understanding of the leak source and our proposed solution.
