020402a Advanced Roof Framing

If the major and minor ridges intersect and the major and minor roofs have different spans, what will change in the roof slope ratios?

• unit rise is constant, unit run varies

• unit run is constant, unit rise varies

• line length is the same but unit rise varies

• unit rise and unit runs are reversed

An unequal slope gable roof has one slope at 1:3 and the other at 1:2. The ridge would be located at?

• 1/8 of the width of the building

• 1/6 of the width of the building

• 2/5 of the width of the building

• 1/4 of the width of the building

An unequal slope gable roof has one slope at 2:3 and the other at 1:2. The ridge would be located at?

• 1/8 of the width of the building

• 1/6 of the width of the building

• 2/5 of the width of the building

• 3/7 of the width of the building

What is the longest piece of baseboard moulding that can fit diagonally (without bending) into an elevator that measures 6' by 7'

on the floor and by 8' high? Answer in the lesser whole foot dimension.

• 10 feet

• 12 feet

• 14 feet

• 16 feet

What is the best way to determine how much shortening is needed on valley rafters on intersecting unequal slope roofs?

• shorten half the diagonal thickness of the major ridge

• shorten half the diagonal thickness of the minor ridge

• measure the shortening on a full or accurately scaled plan view

• shorten the full diagonal thickness of the valley rafter

When constructing an intersecting unequal slope roof if you want to make both the fascia height and overhang dimension

consistent at the roof intersection you will need to?

• Raise the wall height of the steep slope roof

• Raise the wall height of the least sloped roof

• Lower the wall height of the steep slope roof

• Lower the wall height of the steep slope roof

What is the best way to determine how to make the cheek cuts on valley rafters on intersecting unequal slope roofs?

• measure half the diagonal thickness of the major ridge

• measure the cheek cuts on a full size plan view

• measure half the diagonal thickness of the valley rafter

• measure the full diagonal thickness of the valley rafter

On an intersecting un-equal slope roof the run of a valley rafter is?

• only 45 degrees to the plate line

• not 45 degrees to the plate line

• only 90 degrees to the plate line

When valley jack rafters join the valley on an intersecting unequal slope roof, how is the shortening determined?

• measure half the diagonal thickness of the valley

• measure the full diagonal thickness of the valley

• measure half the diagonal thickness of the jack

• measure the shortening on a full size plan layout

If the overhang is to be a uniform width and at the same elevation on all sides of an unequal slope roof, what must be done on the

shorter span roof to achieve this?

• eliminate plumb and level cuts at the birdsmouth

• furring down the soffit to meet the major soffit line

• raise the entire roof to accommodate the soffit

• raise the plate line to accommodate the soffit
