Asphalt Shingle Roof Installation Cost Checklist
When evaluating a cost estimate from asphalt roof installer:
- Most contractors bid by the "square." A square = 100 square feet.
- Is the contractor going to overlay or “tear-off” the existing roof?
- Does the quote include removal and disposal of the existing roof?
- Does the quote include repair or replacement of any rotten or damaged roof deck?
- If the roof deck is being repaired or replaced, what type of plywood is being used (preservative treated, fire retardant treated)?
- What material is being used for the underlayment?
- What is the life expectancy of the shingles (i.e. 20 year, 30 year, lifetime)?
- Will the contractor install ridge and soffit vents?
- Will the contractor install a drip edge?
- Is there a manufacturer warranty on the shingles?
- Is there a warranty on the workmanship?
- What material is being used for the flashing (tin, zinc, copper, aluminum)?
- Is the cost subject to change? If so, what would cause the change?
- Will the contractor ensure that there are no nails or staples in your yard?
- Will you be billed for the work, or do you have to pay upon completion of the job?
- Does the contractor accept credit cards?
