What a New Roof Costs in the Triangle (2026)

Roof quotes in the Triangle can differ by thousands of dollars for the same house. Usually that's because the bids don't describe the same job. The fix is to understand how roofers price, then make every bid show its work.

The national benchmarks

HomeGuide's roof replacement guide (updated November 7, 2025) lists these national figures:

• a typical replacement at $5,700 to $16,000;
• $300 to $600 per square (100 square feet) installed, including materials;
• roofing labor at $150 to $300 per square;
• architectural shingles at $4 to $6 per square foot installed, or $7,500 to $16,000 on average;
• 3-tab shingles at $3 to $5 per square foot installed;
• roofing underlayment at $0.10 to $0.80 per square foot for materials.

Those are averages across the country, not Triangle quotes. Use them to sanity-check bids, not to set a price.

How a roofer builds a price

1. Roof size in squares. Roof area is larger than the house footprint because of pitch and overhangs. A sprawling one-story ranch often has more roof than a two-story house with the same living space, and a steep, cut-up roof has more than a simple gable. Ask each roofer how they measured.

2. Waste factor. Hips, valleys and dormers mean more cut shingles. Complex roofs get a higher waste allowance.

3. Pitch. Steeper roofs need more safety equipment and go slower.

4. Layers. Tearing off two layers costs more than one.

5. Decking. Most bids include a per-sheet price for replacing damaged plywood or OSB and an estimate of how many sheets. That unit price matters.

6. Accessories. Underlayment, ice-and-water membrane, drip edge, starter strips, ridge caps, pipe boots, step and counter flashing, and vents.

7. Disposal and cleanup. Dumpster, haul-away and magnet sweep.

8. Overhead, insurance and profit. Legitimate companies carry liability and workers' compensation insurance, which costs money.

A worked example

Take a hypothetical 1990s two-story house in Cary or North Raleigh measured at 20 squares of architectural shingles, a few valleys and one layer to remove. Using HomeGuide's per-square range of $300 to $600, the installed cost works out to roughly $6,000 to $12,000 before extras like significant decking replacement, a skylight reflash or a chimney cricket. That calculation is only arithmetic on national averages. Real Triangle bids for that house can land above or below it, which is why itemized quotes matter.

Common add-ons

• Decking replacement: priced per sheet.
• Skylights: reflash or replace while the roof is open.
• Chimney flashing or a cricket behind wide chimneys.
• Ventilation changes: new ridge vent, more soffit intake.
• Gutters: often a separate trade.
• Attic insulation: Duke Energy's Smart $aver program includes an insulation rebate through participating contractors; check current terms.

Permits and their cost

Under North Carolina's G.S. 160D-1110, replacing roofing in a single-family home is generally exempt from a building permit for jobs of $40,000 or less, unless structural work is involved. Cary, for example, says same-material re-roofs don't need a permit, but solar reinstallation does. See Cary re-roofing. Ask your roofer whether a permit fee is included.

Making bids comparable

Ask each roofer to list:

1. the number of squares and waste factor;
2. shingle brand, line and color;
3. underlayment type and where ice-and-water membrane goes;
4. new flashing, drip edge and pipe boots;
5. ventilation changes;
6. the per-sheet decking price and how many sheets are included;
7. disposal and cleanup;
8. warranty terms, manufacturer and workmanship;
9. payment schedule.

When the squares differ a lot between bids, ask why. One roofer may have measured more carefully.

Ways to save without cutting corners

• Re-roof before leaks cause interior damage.
• Schedule in a slower season if your roof isn't failing.
• Pick a standard architectural shingle rather than a designer line.
• Combine gutter replacement with the roof.
• Don't skip flashing or underlayment upgrades to hit a number.
