Architectural shingles run about $543 to $755 per square installed in Baltimore, which puts a typical 25-square roof at roughly $13,570 to $18,880. That is 18% above the Maryland baseline. 2026 planning estimates, not quotes.
Roof replacement in Baltimore, Maryland runs roughly 18% above the Maryland state baseline in 2026, driven by local labor rates, permit fees, and code requirements. Historic slate/tile common; permits required for re-roof. Use this guide to size a per-square budget for asphalt shingles, standing-seam metal, or concrete/clay tile on a typical Baltimore home, then refine your estimate with our project estimator.
Baltimore runs about 18% above the Maryland state baseline, so the state figures are scaled by 1.18 to give the local ranges below.
| Material | Per square installed | 20 squares | 25 squares | 30 squares |
|---|---|---|---|---|
| Architectural asphalt shingles | $543 – $755 | $10,856 – $15,104 | $13,570 – $18,880 | $16,284 – $22,656 |
| Standing-seam metal | $1,156 – $1,770 | $23,128 – $35,400 | $28,910 – $44,250 | $34,692 – $53,100 |
| Concrete or clay tile | $1,274 – $1,947 | $25,488 – $38,940 | $31,860 – $48,675 | $38,232 – $58,410 |
Figures are per square — 100 square feet of finished roof — for installed work including tear-off, and are 2026 planning estimates rather than quoted prices. Squares shown allow for a typical 6/12 pitch and 10% waste. Always get three written quotes before committing.
| Roof size | Squares | Asphalt shingle range |
|---|---|---|
| 1,200 sq ft footprint | 15 | $8,142 – $11,328 |
| 1,500 sq ft footprint | 18 | $9,770 – $13,594 |
| 2,000 sq ft footprint | 25 | $13,570 – $18,880 |
| 2,500 sq ft footprint | 31 | $16,827 – $23,411 |
| 3,000 sq ft footprint | 37 | $20,084 – $27,942 |
The Maryland state permit average is around $320; large metros frequently sit above that and may add inspection or scaffolding requirements of their own.
A typical 25-square asphalt shingle roof in Baltimore works out at roughly $13,570 – $18,880 installed. That is the Maryland baseline scaled by the local factor of 1.18.
Historic slate/tile common; permits required for re-roof. Metro labour rates, permit and inspection requirements, and disposal fees all differ from the state average, which is what the 1.18 multiplier represents.
In almost every jurisdiction yes, and a licensed contractor will pull it as part of the job. Replacing a roof without one can cause problems at resale and can give an insurer grounds to dispute a later claim.
Three, from licensed and insured local contractors, each written against the same scope. Ask specifically whether flashing, drip edge, underlayment, ridge vent and decking replacement are included, because that is where quotes usually differ.
