Roofing in Dundalk, MD

Baltimore County, Maryland. Planning figures — not a quote.
What a roof costs in Dundalk
A full tear-off and replacement in Dundalk runs $11,400–$16,300 for architectural asphalt shingles on a 2,000–2,500 sq ft home. Such a footprint carries roughly 22–28 squares of actual roof surface once pitch and waste are counted, which puts the same job at about $452–$647 per square — the unit a contractor's estimate will be built in.
That midpoint sits 19% below the $17,100 median across the 935 cities researched on this basis, placing Dundalk in the 5th percentile for asphalt replacement cost.
Within Maryland, it runs 6% lower than the $14,700 median across the 32 Maryland cities covered here.
| Material | Installed range | Service life | Best suited to |
|---|---|---|---|
| 3-Tab Shingles | $8,900 – $12,900 | 15–22 years | Lowest upfront cost for straightforward rooflines and investor-owned homes. |
| Architectural Shingles | $11,400 – $16,300 | 24–32 years | Most common Maryland choice for value, curb appeal, and balanced durability. |
| Impact-Resistant Class 4 | $13,400 – $20,300 | 30–40 years | Homes that see hail claims or want stronger shingle warranties and insurance credits. |
| Corrugated Metal | $14,800 – $23,800 | 35–50 years | Garages, additions, and homes prioritizing fast water shedding and low maintenance. |
| Standing Seam Metal | $21,800 – $35,600 | 45–70 years | Long-term ownership, superior wind uplift performance, and lower lifecycle cost. |
| Synthetic Slate | $28,700 – $51,500 | 40–60 years | Historic-style neighborhoods needing premium aesthetics without natural slate weight. |
On what is and isn’t included
The $11,400–$16,300 band covers tear-off, underlayment, the new covering, disposal, and labor on a 2,000–2,500 sq ft footprint. It excludes deck replacement — on a Dundalk roof at this price, budget a further $684–$1,956 if the sheathing is soft.
Installed cost divided by service life, using Dundalk’s own figures. Corrugated Metal works out cheapest per year at about $454 — even though it is not the cheapest to buy. The bar shows best case to worst case; the dot is the midpoint. All of it assumes the roof reaches its rated life, which depends on the installation more than the product.
Each tick is one of the 935 cities researched on the same basis. Dundalk sits at the 5th percentile.
What moves the number in Dundalk
The $11,400–$16,300 band above assumes a straightforward roof. These are the items that move a Dundalk quote off it, priced against that same range rather than a national percentage.
| Cost driver | Effect | Why it costs what it does |
|---|---|---|
| Steep pitch (7:12 and above) | +$1,524–$2,632 | Staging, slower coursing, and fall-protection time. On a $13,850 Dundalk roof that is the largest single geometry premium. |
| Removing a second layer | +$1,026–$2,608 | Tear-off and disposal roughly double. Ask whether the $11,400–$16,300 quoted assumed one layer. |
| Sheathing replacement | +$684–$1,956 | The most common change order, priced per sheet once the deck is open. At $13,850 for the roof itself, an undisclosed sheet rate is where a Dundalk quote quietly grows. |
| Two-story access | +$831–$1,385 | Longer material handling on every course, worth roughly $1,108 on this range. |
| Class 4 impact-resistant upgrade | +$2,000–$4,000 | Taken from the Dundalk table above. Whether a carrier credit offsets that $2,000 depends on your own policy — price it, do not assume it. |
| Standing seam metal instead of asphalt | +$10,400–$19,300 | Roughly double the service life, so the comparison is $513 a year against $485 a year, not the sticker price. |

Does this guide cover areas near Dundalk?
