Questions
Quick answers, and the tool for each
How do I turn a roof pitch into degrees?
Divide the rise by 12 and take the arctangent: 4/12 is 18.43 degrees, 6/12 is 26.57 and 12/12 is 45. The converter also works the other way, from an angle back to a pitch. Roof pitch to degrees
How many rolls of ice and water shield does a roof take?
It depends on the eave length, the pitch and how far inside the wall your code wants the barrier. On a 6/12 roof with a 12 inch overhang, the IRC minimum needs about 40 inches up the slope, so two courses at the eaves. Ice and water shield calculator
What does roofing labor cost per square?
Your crew's loaded day cost divided by the squares they finish that day, plus adders for steep pitch, tear off and height. There is no single national rate; work it out from your own crew numbers. Roofing labor cost per square calculator
