Interview Questions for Roof Leak Detection and Repair

Roof leaks can stem from various sources, broadly categorized by their location and cause. Understanding these categories is crucial for effective diagnosis and repair.

• Shingle Damage: This is the most common type, often caused by age, wind damage (lifting, cracking, or missing shingles), improper installation, or impact damage from falling debris. Think of it like a hole in a boat; water will enter where the protection is compromised.
• Flashing Issues: Flashing, the metal material used to seal areas where the roof meets vertical surfaces (chimneys, vents, walls), often deteriorates over time, leading to leaks. This is akin to a poorly sealed seam in a waterproof suit; the vulnerable points will leak.
• Valley Leaks: Where two roof slopes meet (a valley), water can collect and cause leaks if the flashing is improperly installed or damaged. Imagine a river flowing – if the riverbank is compromised, flooding occurs.
• Chimney Leaks: The area around a chimney is especially prone to leaks due to movement and potential cracking of the mortar. Similar to a poorly fitted window, it needs a solid seal to prevent leaks.
• Skylight Leaks: Damaged or improperly sealed skylights can allow water to penetrate the roof. Imagine a poorly sealed sunroof in a car; water will inevitably enter during rainfall.
• Pipe Boots and Vents: These roof penetrations require careful sealing; failure here can lead to significant leaks. This is akin to a weak point in a pipeline system; leaks will occur if not adequately sealed.

Identifying the *type* of leak helps pinpoint the *cause* – whether it’s aging materials, poor installation, or damage from external factors.

My experience encompasses a wide range of leak detection methods. The selection depends on the specific circumstances and the accessibility of the roof area.
