Cost of Peaked Roof Calculation:

FORMULA  =  Truss Count x Sum of ( LF per Truss + Labor per Truss)  or:

• Count = # of Trusses based on 24″ OC + 1 )
• LF of a Truss material. This is roughly the W + L of the kit x 2
• Constant per LF is: Truss-Material-LF
• Count repeated x LABOR per Truss

Actual formula is:  (ceil(({field.61f9f93f98c117.91059867.value}*12+8)/24)+1) *(2*({field.61f9f93f98c117.91059867.value}+{field.61f9f93f98c122.81380793.value})*{Truss-Material-LF} + {Labor-per-Truss})

 

Cost of 2′ Overhang for Sloped Roof

FORMULA  =  Count x # of Joist x 2′ overhang x $/LF + Count # of sheeting needed x $/LF x Length

• Count x # of Joist x $/LF +
  (floor(({field.61f9f93f98c122.81380793.value}*12+16)/24)+1)*2*{2×4-Clear-LF}
  note: 16″ = twice the standard eave and 24 is for O.C. to get the count + 1 truss at the end
• Span (2′ minus 8″) / 5.5″  (5/4 x 6 material)  x $ / LF x ( L of sauna + 2)
• Roofing Material: 2′ overhang or 24″ x (Length (of sauna) + 16″)

+ Truss: Adds 1 Truss X (Length of A Truss  X $ Truss-Material / LF + $ Labor / Truss)

+ Sheeting:  this.value = 2 ft X (ceil ( L/2 ) + 1) ft X $ Cedar-Sheeting-SF

+ Metal Roofing:   this.value = 2 ft X (ceil ( L/2 ) + 1) ft X $ Metal-Roof-SF

+Knee Braces:  10 LF of 4×4-S4S-LF material

 

Actual formula: {Roofing-Multiplier}*(

(floor(({field.61f9f93f98c122.81380793.value}*12+16)/24)+1)*2*{2×4-Clear-LF}+
ceil((2*12-8)/5.5)*ceil(({field.61f9f93f98c122.81380793.value}*12)+16)/12*{5qtrx6-Utility-LF}+
({field.61f9f93f98c122.81380793.value}+2)*{Metal-Roof-SF})
