Replacing an architectural shingle roof typically costs $4–$6 per sq ft installed nationally in 2026, or about $6,700–$13,400 for a roof on a 2,000 sq ft house, according to HomeGuide. Most crews finish in one to three days. The first decision is shingle grade, and whether the decking underneath needs replacing.

What does a roof replacement cost in 2026?
Here are the three numbers most Greenville homeowners ask for first. They are national installed figures; your quote depends on roof size, pitch, layers to remove and decking.
| What | Typical national cost |
|---|---|
| Architectural shingles, installed | $4–$6 per sq ft |
| Whole roof, 2,000 sq ft single-story house (6:12 pitch) | $6,700–$13,400 |
| Replacing rotten decking | $2–$5 per sq ft |
One local roofer, Mighty Dog Roofing of Greenville, publishes its own estimate of $12,000–$18,000 for a typical shingle replacement (their FAQ); that’s one company’s range, not a market average.
How do you know it’s time for a new roof?
Age is the first clue: HomeGuide gives 3-tab shingles 15–20 years and architectural shingles 20–30. Inside that range, these signs mean a replacement is closer than a repair:
- Granule loss: bare, shiny patches on shingles and granules collecting in gutters.
- Curling, cupping or cracked shingles across whole slopes, not one spot.
- Repeated leaks in different places.
- Soft or sagging decking when walked on, or daylight through the roof boards in the attic.
Why Upstate heat and humidity shorten those ranges is covered in how long a roof lasts in South Carolina; if you’re unsure, read repair or replace your roof?
Shingle, metal or flat roof?
Most Upstate re-roofing jobs are asphalt shingle, and this page covers them. For other materials, start on the page that owns them.
- Asphalt shingles: architectural (dimensional) shingles are the standard choice; 3-tab costs a little less and lasts less. The difference is explained in architectural vs 3-tab shingles.
- Metal: about twice the cost up front, with a much longer life; see metal roofing and metal roof vs shingles.
- Premium materials: cedar and synthetic shake and slate and tile.
- Low-slope sections such as porches and additions: TPO and flat roofing.
What should a full roof replacement include?
Hold any roofer to this list. A cheap quote is often cheap because it leaves one of these out.
- Tear-off of every old layer down to the deck.
- A written per-sheet price for replacing rotten decking, so there are no surprises on install day.
- Synthetic underlayment over the whole deck.
- Ice-and-water shield in valleys and around chimneys, skylights and other penetrations.
- New drip edge at the eaves and rakes.
- New flashing at walls and chimneys, and new pipe boots. Reusing old flashing is a common shortcut.
- Ridge vents or other attic ventilation sized for the attic.
- The shingle product named on the contract, installed to the manufacturer’s nailing pattern.
- A magnetic sweep for nails in the yard and driveway, and disposal of the old roof.
- Who pulls the permit, if one is required.
- Manufacturer warranty registration and the roofer’s workmanship warranty, both in writing.
Doing gutters at the same time? See gutters; one crew can usually coordinate both.
What happens on install day?
- Protecting the house: tarps over landscaping, and the driveway kept clear for the dumpster.
- Tear-off: the crew strips the old roof; this is the loudest part, and debris can fall into the attic.
- Decking check: soft or rotten boards are replaced at the agreed per-sheet price.
- New roof: underlayment, ice-and-water shield, drip edge, flashing, shingles and ridge.
- Clean-up: magnet sweep, debris haul-away and a final walk-round with you.
HomeGuide puts a new roof installation with asphalt shingles at 1–3 days. Rain pauses the job, so ask how the roof will be protected overnight.
Do you need a permit to replace a roof?
Permit rules differ between the City of Greenville, Greenville County and each town. Ask your roofer who will pull the permit, and check with your city or county building office before work starts.
What if storm damage or insurance is involved?
A roofer can document storm damage, but under South Carolina law they can’t negotiate your claim or cover your deductible. Read roof insurance claims in South Carolina before you sign anything, and see storm damage roof repair.

Frequently asked questions
Can you roof over old shingles?
Sometimes, but most roofers recommend a full tear-off. Building codes limit how many layers a roof can carry, and a second layer hides rotten decking and adds weight. Ask the roofer and your permit office before agreeing to an overlay.
How do I know if decking needs replacing?
Usually not until the old roof is off. Signs in advance include sagging rooflines, soft spots and water-stained boards in the attic. Agree a per-sheet price in writing so replaced decking is billed at a known rate; HomeGuide puts decking at $2–$5 per sq ft nationally.
Do I need to be home during the replacement?
Not for the whole job. Be there at the start to agree access and at the end for the walk-round. Keep vehicles out of the driveway and pets indoors while the crew works.
Will a roof replacement disturb my attic?
Some dust and debris can fall through gaps in the roof boards during tear-off. Cover stored items in the attic or move them, and ask the crew to check the attic at the end.
What warranty should I get in writing?
Two: the shingle manufacturer’s warranty, registered in your name, and the roofer’s workmanship warranty covering installation. Ask how long each lasts, what it covers and whether it transfers to a buyer.
