Introduction
In this article, I’ll give you the typical costs for installing a new roof in Alabama in 2025, for both residential and commercial buildings. I’ve spent years reviewing contractor bids and researching roofing costs for my clients around the country. The roof cost estimates I provide here were produced by analyzing current material prices, Alabama labor costs, and other relevant factors, including roofing project values from actual Alabama building permit data. The roof systems covered here include asphalt shingles, metal roofing, slate, tile, synthetic composite, cedar shakes, and all of the common types of low-slope commercial roofing.
Roof replacement costs in Alabama are generally lower than the national average, with statewide construction costs averaging about 15% to 20% below the U.S. average. (Compare to national average roof replacement costs.)
Actual roof prices will vary depending on location, roof size, roof slope, complexity, and, of course, the type of roof system installed. Asphalt shingles are by far the most common residential roof covering in Alabama, but alternatives like standing seam metal, clay or concrete tile, and synthetic composite shingles are also used. Commercial “flat” (low-slope) roofs typically use single-ply membranes (EPDM, TPO, and PVC roofing), modified bitumen, or spray-applied polyurethane foam roofing systems.
On average, Alabama residential roof replacement prices in 2025 typically range from around $5 per square foot for basic asphalt shingles to around $29 per square foot for high-end copper roofing. This means a typical 1,700-square-foot pitched roof may cost between $8,500 and $50,000 depending on the type of material you choose.
Commercial roofing generally costs less per square foot, with commercial roof replacement prices ranging, on average, from around $4 per square foot for a ballasted EPDM overlay system with no insulation included to around $13 per square foot for a 2-ply modified bitumen system with enough insulation to meet the Alabama R-25 energy code requirement for roofs with above-deck insulation.
The tables below provide cost information for all roof types and systems.
Climate Considerations for Alabama Roofs
Alabama has a humid subtropical climate, with long, hot, humid summers and generally mild winters. Snowfall is rare throughout the state, though occasional light snow or ice can occur in the northern counties and in higher elevations along the Appalachian foothills. Summers are known for high humidity, frequent thunderstorms, and high demand on building cooling systems. Along the Gulf Coast, Alabama is vulnerable to tropical storms and hurricanes during the Atlantic hurricane season. Annual precipitation is abundant statewide, averaging 50 to 60 inches, with locally higher amounts along the coast and in the southern part of the state.
Cooling degree days far outnumber heating degree days in Alabama, making summer energy efficiency a key concern. Reflective white “cool” roofing materials can help reduce cooling energy loads. Like in other Southeastern states, asphalt shingle roofs in Alabama can develop Gloeocapsa magma colonies (roof algae), especially on shaded or north-facing roof sections. Consider that lighter-colored shingles will reduce heat absorption, but they’ll make algae stains more obvious than darker shingles will.
Given these conditions, homeowners and property managers in Alabama should think about the following:
- Asphalt shingles are the most common and affordable roof covering. Algae-resistant shingles are strongly recommended to help reduce streaks and stains and improve roof appearance.
- Proper ventilation and underlayment are essential for roof performance. Adequate attic ventilation lowers heat buildup during the long summer and helps control year-round moisture levels. Note that improper ventilation can void your roof warranty.
- Metal roofing performs well across Alabama, providing durability, wind resistance, and reduced cooling costs when paired with “cool” reflective finishes. In coastal areas, aluminum panels are preferred for their superior corrosion resistance in salty environments.
- Tile, slate, and cedar are good if installed properly. Cedar shakes and shingles should be installed as Class A fire-rated assemblies for safety. Copper or zinc strips may be used to slow algae, moss, and mildew growth.
- Insulation and attic air sealing are important for lowering cooling costs and improving comfort. High-reflectance roofing or radiant barriers are especially effective in reducing attic heat.
Things to Keep in Mind
These roof cost estimates should be fairly accurate; I make an effort to update them regularly using current material prices and labor data specific to Alabama. Keep in mind that the costs listed below are averages, and actual costs can vary significantly depending on your specific location and the size, configuration, accessibility, and condition of your particular roof.
The residential roof cost estimates provided here are for roof replacements on roofs with a 6/12 pitch and include all standard roof components (underlayment, ice & water shield, fasteners, flashing, etc.). Steeper roofs or roofs with complex designs can increase costs by as much as 30%.
Removal of an existing commercial or residential roof typically adds between $1 and $3 per square foot. For the estimates in the tables below, $1.50 per square foot for tear-off and disposal has been included in all pricing except for the “no additional insulation” commercial roof pricing, which generally indicates a roof recover project.

Table 2: Commercial Roof Costs in Alabama
For energy code purposes, Alabama is in climate zones 2 and 3, and both zones require a minimum of R-25 continuous insulation for commercial roofs with insulation installed entirely above the deck.
When performing a roof recover, these insulation requirements generally do not apply. Recover projects usually involve adding a layer of cover board over the existing system to provide a suitable substrate, followed by the new roof membrane. Roof recovery is not always permitted or advisable.
