Roof Sailing Types of Roofs 3 — Questions and Answers
Question 1: Which roof type is most commonly associated with Mediterranean and Spanish-style architecture in the US?
- Flat roof
- Green roof
- Barrel tile hip roof (Correct answer)
- Skillion roof
Correct answer: Barrel tile hip roof
Barrel tile roofs on hip-style structures are iconic in Mediterranean and Spanish Colonial Revival architecture, especially prevalent in Florida, California, and the Southwest.
Question 2: What structural advantage does a hip roof have over a gable roof in hurricane-prone regions?
- Hip roofs are cheaper to build
- Hip roofs have inward-sloping sides on all four faces, reducing wind uplift (Correct answer)
- Hip roofs are heavier and resist flooding better
- Hip roofs have no overhangs, reducing rain exposure
Correct answer: Hip roofs have inward-sloping sides on all four faces, reducing wind uplift
Hip roofs slope inward on all four sides, which reduces the surface area exposed to wind and minimizes uplift forces during high-wind events like hurricanes.
Question 3: A green roof (living roof) is best categorized by which characteristic?
- A roof painted green for heat reduction
- A roof surface covered with vegetation and growing medium (Correct answer)
- A roof with recycled green-colored shingles
- A roof designed with solar panels
Correct answer: A roof surface covered with vegetation and growing medium
A green roof (or living roof) is partially or completely covered with plants, soil, and a waterproofing membrane system, providing insulation and stormwater benefits.
Question 4: Which roof type is created when two gable roofs intersect at a right angle, forming a cross shape?
- Intersecting gable roof (Correct answer)
- Dutch gable roof
- Saw-tooth roof
- Shed roof
Correct answer: Intersecting gable roof
An intersecting gable (cross-gable) roof is formed when two gable roofs meet at a perpendicular angle, common in homes with L- or T-shaped floor plans.
Question 5: What is a Dutch gable (Dutch hip) roof?
- A flat roof common in the Netherlands
- A hip roof with a small gable added at the top of each hip end (Correct answer)
- A gable roof with no overhanging eaves
- A multi-layered roof with varying pitch angles
Correct answer: A hip roof with a small gable added at the top of each hip end
A Dutch gable roof combines hip and gable elements — it has the hipped slopes of a hip roof but features a small triangular gable at the apex of each hip end.
Question 6: In which climate is a low-pitched or flat roof most commonly an appropriate primary design choice?
- Snowy mountainous regions
- Arid desert climates with minimal rainfall (Correct answer)
- Humid tropical rainforests
- Cold subarctic climates
Correct answer: Arid desert climates with minimal rainfall
Flat and low-pitched roofs are best suited for arid climates because minimal rainfall means drainage is less critical, and the reduced roof mass helps manage heat.
Question 7: What is a skillion roof also known as in the construction industry?
- Lean-to roof (Correct answer)
- Sawtooth roof
- Gable roof
- Pyramid roof
Correct answer: Lean-to roof
A skillion roof is the same as a lean-to or shed roof — a single flat, sloped surface attached at an angle, often used for additions or modern architectural designs.
