Roof Replacement Cost

In the process of calculating the project budget and review estimates, the unfamiliar term “roofing square” is likely to come up. This is a unit of measure unique to roofing that makes it easier for roofers to calculate ordering and material costs. A roofing square is a 10-foot by 10-foot section of the roof or 100 square feet. When discussing the price per square foot, the number usually includes the cost of the roofing material, supplies, protective elements, waste removal, and labor. Some roofers still use a per-square-foot measure, so homeowners will want to be clear about the units the contractor uses while discussing the cost. If it’s helpful, homeowners can refer to an online roof replacement cost calculator for a rough estimate.

Roof Size and Pitch

The size of the roof will determine the cost of supplies, permits, and labor. A new roof on a 1,000-square-foot house costs an average of $4,000 to $5,500 while the cost to replace a 3,000-square-foot home’s roof can rise to an average of $11,200 to $16,000.

In addition, the pitch, or steepness, of the roof can add to the cost. Perfectly flat roofs require extra structure to support. Steeply pitched roofs require additional safety considerations and make them more challenging to navigate. Some very steep roofs may require scaffolding for the contractors to work safely. Additionally, the pitch determines the type of structure that needs to be installed underneath the shingles, adding to the cost. The shape of the pitch can change the cost per square foot as well.

Roof Material

The choice of shingle type or alternate materials probably has the largest overall effect on the cost of reroofing a house and, in most cases, is the choice that a homeowner can actually control. Splurging on luxury materials can mean the roof lasts longer or adds value to the home, but there are plenty of affordable options as well. Basic asphalt shingles typically cost between $2,000 and $4,000 for materials, while luxury copper can cost as much as $40,000 or more. Each material and its average cost is discussed in a section below.

Number of Stories and Roof Accessibility

The height of the home will affect the overall roofing replacement cost. This is a simple factor of time and labor: a single-story home requires less harnessing, fewer ladders, and less time climbing up and down ladders with heavy supplies. A home surrounded by stone walls or large foundation plantings can increase the cost of roof replacement, as the access to the roof is limited to where the roofers can safely place their ladders.

Roof Features

Many of the features that make a home uniquely beautiful and customized—skylights, bay windows, and dormer windows—increase roof replacement cost because of the additional flashing and waterproofing cuts necessary. Bay windows cost more than traditional windows, and replacing the roofing on a bay window also adds to the roof replacement cost. Skylights cost about $150 for a fixed model, plus an additional $500 for installation—an operable or unusually shaped skylight will exceed this cost. Chimneys can cost as much as $5,000 to replace or between $1,000 and $3,000 to partially rebuild. Plumbing vent stacks, and HVAC openings and vents can also add to the new roof cost as the flashing and caulking around these fixtures adds time and materials to the project.

Labor and Permits

On average, labor will cost between $150 and $300 per roofing square ($1.50 to $3 per square foot), contingent on the style, pitch, and accessibility of the roof. Expect labor costs to be on the higher end if the roof has a steep pitch or the roof has an unusual layout. The labor cost will comprise approximately 60 percent of the total project cost, and materials make up the other 40 percent. In most towns and cities, homeowners need a permit to replace a roof so that the town inspectors can make sure that the new roof meets local code and is safely installed. Permit costs vary, but permits are not negotiable or optional. Homeowners will want to check their contract: A professional roofer may be able to pull the permits and include the cost in the total, or the homeowner may need to go to the town offices to request and pay for the permit and schedule the inspection.

Geographic Location

The cost of a new roof can vary significantly depending on factors such as the location of the home and the materials required to withstand local weather conditions. For instance, regions like Florida and the Pacific Northwest typically have higher roofing costs due to specific materials needed to withstand heat, hurricanes, or heavy rainfall.

In Florida, where both heat and hurricanes are concerns, homeowners can expect to pay anywhere from $8,000 to $16,500 for a new roof. Meanwhile, in the Pacific Northwest, where roofs must be truly watertight to handle substantial rainfall, costs can range from $12,000 to $28,000 in California.

While a home’s location is beyond the homeowner’s control, seeking multiple estimates from local roofing contractors can help provide insight into the average costs in the area. Homeowners can search for “roof replacement near me” to explore local pricing options.
