How much will my roof cost depends on three numbers you can measure or choose: your sloped roof area, your material, and your stories. Everything else is adjustment. This guide gives you the per square foot rates, the size tables, and the adjustments, so you can answer the question for your own home without waiting on a sales visit. Our roof repair cost calculator does the same math with a repair versus replace verdict attached.
The single most important discipline is to price the sloped area, not the footprint. A 2,000 square foot home does not have a 2,000 square foot roof unless it is flat. At 6/12 it has 2,236 square feet, at 10/12 it has 2,604, and at 12/12 it has 2,828. Every estimate that skips this step is wrong by the pitch factor, and pitch is the largest single source of estimating error.
Cost Per Square Foot by Material
| Material | Installed range per sq ft | Typical lifespan | Best for |
|---|---|---|---|
| Asphalt shingles (architectural) | $4.50 to $7.50 | 20 to 30 years | Most Lake County homes; best value |
| Metal roofing | $9 to $16 | 40 to 70 years | Long term ownership; steep and low slope alike |
| Flat roof (TPO / EPDM / mod-bit) | $6 to $10 | 20 to 30 years | Low slope and flat roofs; additions and garages |
These are installed ranges, including tear-off and disposal, for the Lake County market. They are not material-only prices, and a material-only price quoted as if it were installed is the most common way a low quote misleads. Always confirm whether a per square foot figure includes labor, tear-off, disposal, underlayment, and flashing before you compare it with another figure.
Cost by Home Size
| Home footprint | Sloped area at 6/12 | Asphalt range | Metal range | Flat range |
|---|---|---|---|---|
| 1,000 sq ft | 1,118 sq ft | $5,500 to $9,200 | $11,100 to $19,700 | $6,700 to $11,200 |
| 1,500 sq ft | 1,677 sq ft | $8,300 to $13,800 | $16,600 to $29,500 | $10,100 to $16,800 |
| 2,000 sq ft | 2,236 sq ft | $11,100 to $18,400 | $22,100 to $39,400 | $13,400 to $22,400 |
| 3,000 sq ft | 3,354 sq ft | $16,600 to $27,700 | $33,200 to $59,000 | $20,100 to $33,500 |
These ranges assume a single story home with the moderate pitch handling factor the calculator applies at 6/12. Two stories add about 15 percent, three stories about 30 percent. A simple gable roof lands near the bottom of each range; a cut-up roofline with valleys, hips, dormers, and skylights lands near the top. Your own roof sits somewhere inside its row, and the calculator places it more precisely from your inputs.
What Your Roof Will Cost If You Only Need a Repair
Not every roof question ends in replacement. A patch repair for a lifted flashing or a few shingles typically runs 350 to 1,200 dollars, and a partial section repair typically runs 6 to 12 dollars per square foot of the repaired area. If your damage is under 25 percent and your roof is under 20 years old, a repair is usually the better spend, and the money you save against replacement is real money, not a delay tactic.
The trap is paying partial prices repeatedly on a dying roof. Three patches at 800 dollars each on a 24 year old roof is 2,400 dollars that does not reduce the replacement price, and the fourth leak is already forming. That is why the decision rule uses age alongside damage: a young roof earns repairs, an old roof earns a replacement, and the threshold between them is the 25 percent damage line combined with the 20 year age line.
Getting Your Exact Number
Tables give ranges; your roof has one price. The fastest route to it is the pillar calculator: enter footprint or sloped area, pitch, material, damage extent, age, and stories, and it returns patch, partial, and full replacement ranges plus a verdict and a fairness check for any quote you already hold. Then get two written quotes at the same scope and material, and compare lines before totals. A final quote is confirmed only after an on-site inspection, because no table can see your deck, your flashing, or your valleys.
One last caution on per square foot figures you find online: national averages blend regions with very different labor and disposal costs, and Lake County sits above the national middle. A figure that looks typical nationally can look low locally, and a local quote that looks high nationally can be perfectly normal here. Judge quotes against local ranges like the ones on this page.

Frequently Asked Questions
How much will my roof cost for a 2,000 square foot house?
For a 2,000 square foot footprint at a 6/12 pitch, the sloped roof measures about 2,236 square feet, and a full asphalt shingle replacement typically falls between about 11,100 and 18,400 dollars for a single story home. Metal runs roughly 22,100 to 39,400 dollars for the same roof, and a flat system 13,400 to 22,400 dollars. A final quote is confirmed only after an on-site inspection.
How much does a new roof cost per square foot?
A new asphalt shingle roof typically costs 4.50 to 7.50 dollars per square foot installed, including tear-off and disposal. Metal roofing typically costs 9 to 16 dollars per square foot, and a flat roof system typically costs 6 to 10 dollars per square foot. Multiply your sloped roof area, not your footprint, by the rate for your material.
How much does roofing cost per square foot for labor alone?
Labor is typically about 40 percent of the installed total, which works out to roughly 1.80 to 3.00 dollars per square foot on an asphalt job, with the rest going to materials, tear-off, and disposal. Labor share rises with pitch, stories, and roof complexity, and falls on simple low slope roofs where crews move fast.
How much does a roof cost on a house with a steep pitch?
A steep 12/12 roof has about 41 percent more surface than its footprint, so the area alone pushes the total up, and steep-roof handling adds further cost for safety setup and slower work. Expect a steep roof to cost roughly 25 percent more than a low slope roof of the same footprint, before any material difference.
How much will my roof cost if I only need a repair?
A small patch repair typically runs 350 to 1,200 dollars, and a partial section repair typically runs 6 to 12 dollars per square foot of the repaired area. If damage is under 25 percent and the roof is under 20 years old, a repair is usually the better spend. The roof repair cost calculator prices all three scopes for your roof.
