Test 3: Problem-Solving and Practical Applications

Describe a scenario where improperly installed flashing causes water damage. (Page 28)

• Improperly installed flashing can lead to water seeping into walls, causing mold and structural damage.

• Improperly installed flashing can enhance the aesthetic appeal of a building.

• Improperly installed flashing can improve the insulation of a building.

• Improperly installed flashing can reduce the risk of fire damage.

How does a valley design influence the risk of water pooling?

• It increases the risk of water pooling.

• It decreases the risk of water pooling.

• It has no effect on the risk of water pooling.

• It depends on other environmental factors.

What adjustments must be made to shingle installation for roofs with a steep pitch?

• Use longer nails for better grip.

• Install additional underlayment layers.

• Increase the overlap of shingles.

• No adjustments are necessary.

If a roof requires 15 squares, how many square feet does this represent?

• 150 square feet

• 1500 square feet

• 1000 square feet

• 2000 square feet

How can underlayment be used to mitigate ice dam formation?

• By providing additional insulation to the roof

• By acting as a waterproof barrier under the shingles

• By increasing the roof's slope

• By improving attic ventilation

What are the consequences of inadequate overlap in ridge cap installation?

• Water leakage and roof damage

• Improved ventilation

• Enhanced aesthetic appeal

• Increased insulation

What role does a drip edge play during heavy rainfall?

• It prevents water from seeping under the roofing paper.

• It enhances the aesthetic appeal of the roof.

• It helps in insulating the roof.

• It supports the roof structure.

Valleys are particularly vulnerable to leaks because:

• They are often located at lower elevations.

• They have a higher concentration of water when it rains.

• They are more exposed to wind and rain.

• They have a natural drainage system.

What is the recommended fastening method for sheathing?

• Nails

• Screws

• Staples

• Adhesive

How does proper starter strip alignment influence roof aesthetics?

• It ensures a uniform appearance of the roof edge.

• It prevents water leakage.

• It increases the lifespan of the roof.

• It reduces the cost of roofing materials.
