How Much Does It Cost To Replace A 1000 Sq Ft Roof?
The average lifespan of a roof can range from 15 to 50 years. How long your roof lasts can depend on your location, roofing materials, and how well the roof was initially installed. Sooner or later, however, every roof requires replacing.
Knowing what to expect when that time comes can help you budget, prepare, and make smart choices. Here’s a breakdown of how much it costs to replace a 1,000 square foot roof on average.
Asphalt Shingle Roofs
Asphalt shingle roofs are one of the most common types of roofs nationwide. Asphalt shingles come in three types:
3-tab shingles are durable, economical, and the most affordable type of asphalt shingle. Architectural shingles provide more creative and aesthetic options for roof finishing and typically last longer than 3-tabs.
Luxury shingles tend to mimic the appearance of slate or cedar roofing. They offer the highest level of visual appeal and durability, but also cost substantially more than the other types of shingles.
On average, asphalt shingles cost between $3.50 and $5.00 per square foot.
The total cost to replace a roof can be influenced by:
- Roof slope
- Roof complexity
- The need to remove previous roofing or make repairs before replacement
- Local building codes
- Geographic location
When all of those factors are taken into account, the average cost of roof replacement service for a 1,000 square foot roof using shingles comes out to between $5,000 and $11,000.
Metal roofing comes in a variety of materials, including:
Metal roofing can be an excellent investment as most metal roofs last a minimum of 40 years and many remain in good shape for twice that long. Replacing old roofs with new metal ones, however, can be relatively expensive upfront.
Pricing ranges from around $6 per square foot for Galvalume to nearly $30 per square foot for Copper. This puts the total cost of replacing a 1,000 square foot roof between $6,000 and $30,000.
Slate or Tile Roofs
The durability and elegance of slate and tile roofs have made them popular choices in the United States since the early 1600s. Like metal roofing, slate and tile often last between 50 and 100 years making them cost-effective choices in the long-term but expensive to install.
Tile costs an average of $5 to $8 per square foot, while slate costs between $6 and $15 per square foot. Thus the average cost of replacing a 1,000 square foot roof with tile is between $5,000 and $8,000 and redoing the same roof in slate would cost between $6,000 and $15,000.
Tile and slate, it should be noted, are particularly subject to price variations related to the shape, slope, and complexity of a roof. If your roof is steeply sloped, multi-hipped, or contains other special features, expect to see your baseline cost at a higher price point than these plain roof estimates.
Flat Roof Systems
As with most other categories of roofing materials, flat roof systems come in a variety of types. The most common for residential properties are:
- Single-layer membrane roofing
- Modified bitumen roofing
- Built-up roofing (BUR)
Single-layer membrane roofing may also be called elastomeric or plastomeric membrane roofing, and can be further sub-divided into an array of types including:
- PVC (polyvinyl chloride)
- Neoprene (polychloroprene)
- Chlorinated polyethylene and chlorosulfonated polyethylene sheets
- EPDM (ethylene propylene diene monomer)
While pricing can vary widely depending on which type of system you use, in general, flat roofing systems cost between $4 and $6 per square foot. This makes the price to replace a 1,000 square foot roof between $4,000 and $6,000.
Other Roofing Materials
There are a few other less common types of roofs whose costs are worth exploring.
Wood or cedar shake roofs last between 30 and 40 years and cost around $8 per square foot. The cost of replacing a 1,000 square foot roof with them starts around $8,000.
Vinyl roofing lasts an average of 25 to 40 years and costs around $4.50 per square foot. A 1,000 square foot roof would cost around $4,500. Spray Polyurethane Foam roofing lasts about 20 years but costs the same as vinyl roofing.
Concrete roofing lasts between 40 and 100 years and costs around $15 per square foot. The cost of replacing a 1,000 square foot roof would start around $15,000.
Solar roofing, also called photovoltaic shingles or building-integrated photovoltaics, starts at around $22 per square foot. That puts the cost of a 1,000 square foot roof at about $22,000.
Calculating Roof Replacement Costs
When planning a roof replacement project, experts advise adding an extra 10 percent to your original estimate. So, for instance, if you plan to install a Galvalume roof for a base price of around $6,000, you would add an extra $600 and anticipate a price of closer to $6,600 altogether.
This allows you to comfortably accommodate the various factors that can bump up roof pricing such as:
- Unexpected sub-layer repairs
- Old roof removal
- Additional supplies or labor needed to accommodate irregularities or special roof features
- Taxes, service charges, and other unexpected fees
Costs of Repairing a 1,000 Square Foot Roof
Damage to roofs can occur from storms, accidents, and other unfortunate events. While damage can lead to the need to replace a roof, in some cases where it is localized roof repairs can be made instead.
Here are the average costs nationwide to repair common types of damage to a roof.
- Broken or Missing Shingles: $30 and higher
- Ice Dams: $50 to $120
- Cracked Flashing: $20
- Skylight leaks: $25 to $80
- Cracked Vent Booting: $10 to $20
Most homeowners spend between $360 and $1,500 each time they need to repair their roofs, but small repair projects can cost as little as $150.
The exact cost of repairing your roof will depend on:
- The type of damage incurred
- The extent of the damage
- What kind of roofing you have
- Your geographic location
- Local demand
