Estimating the Cost of Architectural Shingles

If you choose a heavier shingle, known as an architectural shingle, the cost will be up to twice as much as asphalt shingles. However, you can then choose a 40 year or 20-year shingle. Groome said that you can expect to pay an average of $4,500 to $5,500 for an average-sized roof with complete tear-off (if no repairs are needed) for this type of shingle.
