With a building length of 8600 mm and width of 8400 mm, a (level) roof overhang of 600 mm,

the roof is 9800 mm long and 9600 mm wide.

At an angle of 23 °, the overall height above outer wall is 1864 mm. (Rise per 1000 Run = 424)

The ridge top is 1854 mm above top of wall, ridge bottom is 1779 mm

The roof area is 102.2 m² and sheathing angle is 47.37 °

Rafter Centres = 1200 mm

Creeper shortening = 1303.6 mm

38.8 lineal metres Fascia.

38.8 lineal metres Eave @ 600 mm overhang = 23.3 m² Level ( or 25.3 m² at 23 ° )

Roof Volume (top of wall/plate to under rafters) = 43.43 m³

Roof Volume (top of wall/plate to top of rafters) = 49.31 m³

End Frieze Block (Bird Block) Plumb Angle 21.3° - Side Angle 40.6° (Blocks perpendicular to roof angle)

224.7 lineal metres Batten, including battens beside hips and 15% waste

Batten Spacing Adjusted Evenly to 856.2 mm

Batten Mitre Cut = 47.37° - Batten Bevel Angle = 16°

You need: 1 Ridge @ 250 × 75 × 50

6 Common Rafters @ 5219 × 75 × 50

4 Hips @ 7073 × 75 × 50

Creepers * Total Lengths INCLUDING plumb-cuts

8 @ 3931

8 @ 2628

8 @ 1324

* 4 of each set of 8 creeper lengths are right side and 4 are left side.

(opposite side cuts) See Creeper Templates and top diagram.

Optimum Creeper Length 12 @ 5255 * No Waste what's this?

Total Cubic 0.461 m³ (No Battens)

224.7 lineal metres Batten (including 15% waste)

Running Batten setout points: (from lower end of rafter up)

If using a Circular Saw or Compound Mitre saw, set saw bevel angle to 45° to obtain Creeper and Hip side angles.

With the saw bevel angle set to 45°, cutting hips and creepers at the plumb cut angle will produce correct side angles.
