What a roof costs in Dunwoody
A full tear-off and replacement in Dunwoody runs $9,800–$18,600 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 $389–$738 per square — the unit a contractor's estimate will be built in.
That midpoint sits 17% below the $17,100 median across the 935 cities researched on this basis, placing Dunwoody in the 7th percentile for asphalt replacement cost.
Within Georgia, it runs 6% higher than the $13,425 median across the 56 Georgia cities covered here.
| Material | Installed range | Service life | Best suited to |
|---|---|---|---|
| 3-Tab Shingles | $7,600 – $14,700 | 15–22 years | Budget-first replacements on simple rooflines and rental properties. |
| Architectural Shingles | $9,800 – $18,600 | 24–32 years | Most common Georgia choice balancing durability, curb appeal, and cost. |
| Impact-Resistant Class 4 | $11,600 – $22,900 | 30–40 years | Storm-prone corridors and owners prioritizing hail and wind resilience. |
| Corrugated Metal | $8,800 – $23,300 | 35–50 years | Low-maintenance performance and strong rain-shedding on secondary structures. |
| Standing Seam Metal | $16,000 – $39,600 | 45–70 years | Long-term ownership, premium durability, and strong wind performance. |
| Synthetic Slate | $18,800 – $49,100 | 40–60 years | Premium aesthetics for historic or luxury homes without natural-slate weight. |
On what is and isn’t included
The $9,800–$18,600 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 Dunwoody roof at this price, budget a further $588–$2,232 if the sheathing is soft.
Installed cost divided by service life, using Dunwoody’s own figures. Corrugated Metal works out cheapest per year at about $378 — 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. Dunwoody sits at the 7th percentile.
What moves the number in Dunwoody
The $9,800–$18,600 band above assumes a straightforward roof. These are the items that move a Dunwoody 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) | +$1,562–$2,698 | Staging, slower coursing, and fall-protection time. On a $14,200 Dunwoody roof that is the largest single geometry premium. |
| Removing a second layer | +$882–$2,976 | Tear-off and disposal roughly double. Ask whether the $9,800–$18,600 quoted assumed one layer. |
| Sheathing replacement | +$588–$2,232 | The most common change order, priced per sheet once the deck is open. At $14,200 for the roof itself, an undisclosed sheet rate is where a Dunwoody quote quietly grows. |
| Two-story access | +$852–$1,420 | Longer material handling on every course, worth roughly $1,136 on this range. |
| Class 4 impact-resistant upgrade | +$1,800–$4,300 | Taken from the Dunwoody table above. Whether a carrier credit offsets that $1,800 depends on your own policy — price it, do not assume it. |
| Standing seam metal instead of asphalt | +$6,200–$21,000 | Roughly double the service life, so the comparison is $526 a year against $408 a year, not the sticker price. |
What the weather does to roofs in Dunwoody
Across the 1991-2020 climate normals, Dunwoody averages summer highs averaging 88°F, 53 in of precipitation a year, and 39 days a year above 90°F — the loads a replacement here is bought to survive.
The dominant stressor is high-intensity rainfall. Dunwoody’s 18 days a year of 1 in-plus rainfall sits in the 95th percentile among the 1,037 cities covered here. 18 days a year drop an inch or more, and 39 drop at least half an inch. Those are the days that overwhelm an undersized valley or gutter and push water sideways under the course above. Drainage capacity belongs in the Dunwoody scope conversation, not just shingle grade.
53 in of annual precipitation compounds it — in the 88th percentile among the same set. 53 in a year arriving across roughly 18 days of 1 in-plus rainfall means volume and intensity both. Water finds any lap detailed against the slope, so underlayment coverage, valley metal width, and pipe-boot type matter more in Dunwoody than in a market where the same total arrives gently.

What matters at inspection here
Driven by Dunwoody’s measured climate
- Valley and penetration detailing. 53 in a year across 18 heavy days finds every lap detailed against the slope. Name valley metal width and pipe-boot type in the scope.
- Deck condition and fastener holding. With no single climate hazard dominating in Dunwoody, sheathing that will not hold a nail is the most likely reason a scope changes mid-job.
