Cost factors to reroof a house

The following factors affect the cost of roof replacement:

  • Roof size and shape – Complex roofs, multiple stories, skylights, and chimneys increase the cost.

  • Roof slope and pitch – Roofs with steep pitches over 6:12 require extra safety precautions and more labor, increasing costs.

  • Material – Asphalt shingles cost the least, while slate and solar shingles are the most expensive to install.

  • Roof over / reroofing – Installing new shingles or metal on top of the old roof material saves on removal costs but reduces the roof's lifespan. Most cities limit roofs to a maximum of two roof layers.

  • Roof underlaymentRoofing underlayment costs $0.10 to $0.80 per square foot

    for materials, depending on the type. Roof replacement estimates typically include new underlayment.

  • Flashing – Roof flashing is a thin piece of sheet metal installed in areas prone to leaks, such as roof valleys and chimneys. Most installers include new flashing in the estimate.

  • Roof repairs – Roof repairs cost $150 to $400 to patch small leaks or $1,000 to $3,000 for structural repairs to fix a sagging roof.

  • Roof penetrations / ventilationRoof vent installation costs $200 to $700.

  • Soffits and fascia Soffit replacement costs $4 to $22 per linear foot. Fascia replacement costs $5 to $12 per linear foot.

  • Drip edge – Installing a drip edge costs $1.50 to $3.00 per linear foot and redirects water away from the fascia into the gutters to prevent water damage.

  • Gutter installation/replacementGutter replacement costs $6 to $17 per linear foot. New gutter installation costs $5 to $15 per linear foot.

  • SkylightsSkylight installation costs $1,600 to $4,200 on average, while skylight replacement costs $800 to $2,400.

  • PermitsRoof replacement permits cost $100 to $500, depending on location.

  • Roof inspection – A roof inspection costs $100 to $400 to detect problems and gauge the remaining life of the roof.

Cost to tear off and rebuild a roof

The cost to tear off a roof is $1 to $5 per square foot for labor to remove the old material, depending on the type and number of layers:

  • Tearing off shingles or metal costs $1 to $3 per square foot on average.

  • Removing heavier materials like slate or tile costs $2 to $5+ per square foot.

Full roof replacement cost

A full roof replacement may require replacing the underlying support structure, including the decking and trusses. Replacing the entire roof is often necessary after severe water or storm damage.

  • Roof decking replacement costs $2 to $5 per square foot installed. Roof decking, also called sheathing, is a plywood layer that supports the underlayment and roof material.

  • Roof truss replacement costs $5 to $14 per square foot installed. Roof replacement may require additional trusses for structural support if installing a heavier material like slate or tile.

  • Framing a roof costs $6 to $15 per square foot installed. Replacing a flat roof with a pitched roof requires new framing.
