Generally speaking, the cost of replacing your roof can be anywhere from $2,000 for a small, single story house, to $12,000 for a larger house with complicated roof lines, dormers and the like.
That being said, most roofing contractors (and many insurance companies) will price their roof replacement services within $3.50 to $5.00 per square foot or $350 to $500 per square of architectural shingles installed. A square is equal to 100 square feet of roof surface. An average roof size is about 1,700 square feet.
