  1. What is the correct installation sequence for drip edge at the rake (gable) edge of a roof?

    Answer: Drip edge installed over the underlayment

    At rake edges, drip edge is installed over the underlayment so water is directed away from the fascia and off the roof edge correctly.

  2. A home inspector observes that a flat roof has significant ponding water 48 hours after rainfall. What is the concern?

    Answer: Ponding can accelerate membrane deterioration and indicates inadequate drainage

    Ponding water that remains 48 hours after rainfall accelerates membrane degradation and indicates poor slope or blocked drainage, both of which are reportable deficiencies.

  3. Which roofing material requires the installation of a solid or spaced wood deck for proper performance?

    Answer: Wood shingles and shakes

    Wood shingles and shakes require either solid or spaced sheathing to allow airflow beneath them for drying and to prevent moisture-related decay.

  4. When inspecting a metal roof, an inspector notices white, powdery deposits near fasteners. What does this indicate?

    Answer: Galvanic corrosion from dissimilar metals in contact

    White powdery deposits near fasteners typically indicate galvanic corrosion, which occurs when dissimilar metals are in contact in the presence of moisture.

  5. What is the minimum headlap required for standard 3-tab asphalt shingles?

    Answer: 2 inches

    Standard 3-tab asphalt shingles require a minimum headlap of 2 inches to provide adequate weather protection at the overlapping joint.

  6. Which type of ventilation system works on the principle of convection to move air through an attic?

    Answer: Ridge-and-soffit ventilation

    Ridge-and-soffit ventilation is a passive system that relies on convection (stack effect): cool air enters at the soffit and warm air escapes at the ridge.

  7. What condition is described when an asphalt shingle's tabs curl downward while the bond strip area remains flat?

    Answer: Clawing

    Clawing occurs when shingle tabs curl downward while the upper portion stays flat, typically caused by moisture imbalance or improper ventilation.
