How to Estimate a Cedar Shake Roof
Contractor method to estimate a cedar shake roof by area, grade, ventilation and install with clear materials and labor lines.
A cedar shake roof is a premium job priced by area and grade of shake, and the ventilation and underlayment matter as much as the shakes themselves. This guide covers measuring the roof, choosing the shake grade, and pricing the ventilation and removal.
THE SHORT ANSWER
How to Estimate a Cedar Shake Roof
1,200 sq ft of No. 1 cedar shake with ventilation and install at $5/sq ft totals about $13,200.
Measure the roof and choose the grade
Price by the roof area and the shake grade. Premium grades are thicker and cost more but look better and last longer.
- Roof area
- Shake grade
- Ventilation
- Underlayment
Ventilation keeps the shakes alive
Cedar needs air on both sides or it rots. Ridge and eave ventilation is not optional on a shake roof; include it.
Underlayment protects against leaks
A quality underlayment under the shakes adds a second line of defense. It is a small line with real value.
Removal and disposal
If the old roof comes off, removal and disposal add a real line. Confirm whether the bid is a re-cover or a tear-off.
