Cost by project size
Generated from the same unit pricing the calculator uses.
| Project size | Estimated range |
|---|---|
| 1,000 sq ft of roof area | $6,000 – $15,000 |
| 1,300 sq ft of roof area | $7,800 – $19,500 |
| 1,700 sq ft of roof area | $10,200 – $25,500 |
| 2,200 sq ft of roof area | $13,200 – $33,000 |
| 2,900 sq ft of roof area | $17,400 – $43,500 |
Based on Charleston pricing of $6–$15 per sq ft of roof area.
Cost by roof scope
Roof pricing moves on area, pitch, how many layers come off and what the deck looks like underneath. Every row is priced against the Charleston median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Overlay on a simple ranch roof | Single layer, 4:12 pitch, no tear-off | $10,900 – $14,400 |
| Standard tear-off and replace | One layer removed, architectural shingle, walkable pitch | $15,000 – $20,200 |
| Two-layer tear-off | Extra removal and disposal, same footprint | $17,600 – $23,800 |
| Steep or cut-up roof | 8:12+ pitch, multiple valleys, dormers, staging | $22,000 – $29,900 |
| Replacement with deck repair | Partial resheathing found after tear-off | $20,200 – $28,200 |
- • Tear-off and disposal is priced per layer — quotes that omit a second layer are the most common source of change orders.
- • Decking is unknown until the old roof is off. Reputable quotes state a per-sheet resheathing price up front.
- • Pitch above 7:12 requires fall protection and slows the crew, which shows up as labor, not material.
Basis: Each scope is priced as a multiple of the modeled Charleston median for roof replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Labor in the price
$8,800
50% of the median — the rest is material, disposal and permit.
Because labor is 50% of this job, Charleston wage levels move the price far more than material prices do. A quote well under this labor figure usually means a smaller crew, a longer schedule, or unlicensed help.

Frequently asked questions
How long does a roof replacement take?
Most single-family asphalt shingle roofs are torn off and re-covered in one to three working days. Tile and metal roofs typically take three to seven days. The overall timeline, including permit issuance and final inspection, is usually two to six weeks.
Can I replace my own roof in Florida?
Florida allows an owner-builder permit on a home you own and occupy, but you must appear in person, sign the owner-builder disclosure statement, and take on liability for code compliance and inspections. Most insurers and mortgage lenders prefer a licensed roofing contractor.
Does homeowners insurance pay for a new roof?
Insurance generally covers sudden damage from a covered peril such as a windstorm, not wear-out from age. Florida carriers commonly require a roof inspection once the roof reaches 15 years, and may offer only actual cash value on older roofs.
Can you roof over existing shingles?
The Florida Building Code allows a limited number of roof coverings on a structure, but re-covering is restricted and many jurisdictions require a full tear-off when more than 25% of the roof area is being repaired or replaced. Verify with your local building department before assuming a re-cover is allowed.
