A 1,800 sq ft asphalt shingle roof runs about $6,320 to $10,690 installed in Florida (2026), or $2,110 to $2,430 for materials only.
$351 to $594 per roofing square, from real Florida pricing (retailer pricing at ZIP 33101 plus RoofingCalc installed ranges).
| Materials | $2,110 to $2,430 Asphalt Shingle and accessories for about 18 squares. |
| Labor | $2,610 to $5,120 Crew, install, and staging. The largest share of most jobs. |
| Tear-off and disposal | $1,090 to $2,150 Stripping the old roof and hauling it off. Rises with extra layers. |
| Permit and inspection | $510 to $990 Florida re-roof permit and final inspection. An approximate derived share. |
| Total installed | $6,320 to $10,690 Typical $8,500. Low, typical, and high across a normal range of roofs. |

What affects the cost of a 1,800 sq ft roof.
An 1,800 sq ft roof is about 18 squares, a common size for a three- or four-bedroom Florida home. By this point the fixed costs of the job are fully absorbed into the per-square price, so the estimate scales predictably: material and labor rise roughly in step with the square count, and the total sits comfortably inside the linear model. Small pricing differences between contractors at this size usually come down to crew rates and material grade rather than the size of the roof itself.
Geometry is still the main reason two 1,800 sq ft roofs cost different amounts. A simple gable installs quickly; a hip roof with multiple valleys, a chimney, and skylights uses more flashing and takes longer. Story count and pitch add labor, and tear-off condition matters, since a roof carrying two layers of old shingle roughly doubles the disposal weight and the dump fees compared with a single-layer strip.
Florida code requirements, the permit, the final inspection, a rated underlayment, and secondary water protection in the wind zone, are included in these ranges. The estimate is scaled linearly from a 30-square baseline, and 1,800 sq ft is close enough to that baseline for the figure to be a solid planning number. Treat it as a starting point and confirm with a contractor who has measured the roof before committing a budget.

All roof costsA 1,800 sq ft asphalt shingle roof costs about $6,320 to $10,690 installed in Florida in 2026, with a typical price near $8,500. That works out to roughly $351 to $594 per roofing square. Materials are only part of the bill; the rest is labor, tear-off and disposal, and the permit and inspection.
A 1,800 sq ft roof is about 18 roofing squares. Roof area is usually larger than a home's floor area because it follows the pitch and the overhangs, so a 1,800 sq ft roof does not mean a 1,800 sq ft house. Contractors price by the square, which is why the size in square feet is the number that drives the estimate.
An entry or builder-grade asphalt shingle roof typically lasts about 15 to 20 years in Florida. The state's sun, heat, and wind age shingles faster than in cooler climates, and insurers weigh roof age heavily, so a 1,800 sq ft asphalt roof past its mid-teens is often the one a carrier asks to be replaced. Architectural shingles on the same 1,800 sq ft roof usually last several years longer.
Florida homeowners insurance generally covers a roof replacement when the damage comes from a covered peril such as a hurricane or hail, not from ordinary age and wear. Because a 1,800 sq ft asphalt roof runs about $6,320 to $10,690, carriers scrutinize roof age closely, and an older roof can raise premiums or need replacing before they will write a policy. A wind-mitigation inspection can lower the premium either way.
