Source: This Old House, new roof cost guide (Homewyse cost data), updated October 7, 2026. Roof area, not floor area.
The average roof replacement cost for an asphalt shingle roof is about $5.16 per square foot installed, according to This Old House's 2026 cost guide. On the average U.S. roof of about 1,700 square feet, that is roughly $8,772. Metal runs closer to $19 per square foot and clay tile about $22. Your own number depends on the roof's real size, its pitch and shape, the condition of the decking under the old shingles and the product you pick.
This guide explains how a roof replacement is priced in Texas: the national ranges and where they come from, how to estimate your roof's size from your floor plan, the line items that move a quote up or down, and a few Texas specifics such as sales tax and hail-rated shingles. If you already think your roof is due, our roof replacement page walks through how we decide and what install day looks like.

Roof replacement cost by roof size and material
Roofers measure in squares, and one square is 100 square feet of roof. National guides usually quote by the square foot, so multiply by 100 to compare with a per-square number on an estimate.
This Old House's guide gives these average installed totals, using builder-grade materials and a standard pitch:
| Roof size | Asphalt shingles | Metal | Clay tile |
|---|---|---|---|
| 1,000 sq ft (10 squares) | $5,160 | $19,300 | $22,210 |
| 1,500 sq ft (15 squares) | $7,740 | $28,950 | $33,315 |
| 2,000 sq ft (20 squares) | $10,320 | $38,600 | $44,420 |
| 2,500 sq ft (25 squares) | $12,900 | $48,250 | $55,525 |
| 3,000 sq ft (30 squares) | $15,480 | $57,900 | $66,630 |

These are averages, not quotes. The same publisher's size-by-size pages, built on RSMeans data from Gordian, show how wide the real spread is: for a 2,100-square-foot house the average roof replacement comes to about $9,927, with typical prices from $7,630 to $25,270 depending on material, location and the number of stories (This Old House, updated June 8, 2026).
Most Texas homes we see are re-roofed in architectural asphalt shingles, so the asphalt column is the one most homeowners should read first. The guide notes that premium 30- or 50-year architectural lines cost more than basic three-tab shingles, so expect an architectural shingle to sit above the bare average.
How big is your roof, really?
The most common mistake when estimating the cost of roof replacement is using the home's square footage. Your roof is not the same size as your floor plan. Overhangs add area, pitch adds area, and the number of stories changes everything.
This Old House works it out this way for a 2,100-square-foot home, assuming a 6/12 pitch and one-foot eaves:
| House | Approximate roof area | Rule of thumb |
|---|---|---|
| One story, 2,100 sq ft | About 2,588 sq ft | About 120 sq ft of roof per 100 sq ft of living space |
| Two story, 2,100 sq ft | About 1,333 sq ft | About 60 sq ft of roof per 100 sq ft of living space |

That is why a sprawling single-story ranch in McKinney or Allen can cost more to re-roof than a larger two-story house down the street. The two-story home stacks its living space under a smaller roof. A steep pitch pushes the area up further, and so do porches and garages under the main roofline.
What drives the price of a roof replacement
Two homes with the same roof area can still get quotes thousands of dollars apart. These are the items that move it.
Labor and access
This Old House puts labor at about 65% of total project cost. Anything that slows the crew raises the price: a steep roof that needs extra safety setup, a third story, tight side yards where the dump trailer cannot get close, or a roof over a pool and landscaping that needs extra protection.
Valleys, hips, dormers and penetrations
A plain gable with two long slopes goes quickly. Every valley, hip, dormer, skylight, chimney and vent pipe needs cutting, flashing and extra care. A cut-up roof costs more per square than a simple one of the same size.
Tear-off and disposal
Stripping the old shingles and underlayment, hauling them off and paying the disposal fees is real labor and real tonnage. This Old House lists old-roof removal and debris disposal among the costs homeowners overlook. Most codes allow a second layer of asphalt over the first, which is cheaper up front, but a tear-off is the only way to see the decking.
Decking
Soft or rotted boards under the old roof have to be replaced before anything new goes on, and nobody can count them until the shingles are off. In This Old House's 2026 survey of 1,000 homeowners, about 23% of those who found hidden roof damage paid more than their estimate, against 13% of those who did not. Ask any roofer how decking is priced on their estimate, per sheet or per board, before you sign.
The small parts
Underlayment, drip edge, flashing, pipe boots, ridge vents and ice and water barrier in valleys are all part of a full replacement. They are easy to leave off a low bid and expensive to skip on the roof. Attic ventilation belongs on the list too: in a Texas summer, a roof that traps heat in the attic ages faster from the underside.
The shingle you choose
Three-tab is the cheapest asphalt option, architectural costs more, and impact-resistant shingles cost more again. Metal is a different price band altogether; our guide to standing seam metal roof cost covers that side.
Texas specifics: sales tax, hail and Class 4 shingles
Sales tax on a residential roof
In Texas, the labor to repair, remodel or restore residential real property is not taxable, according to the Texas Comptroller's guide to real property repair and remodeling (publication 94-116). Under a lump-sum contract, the contractor pays tax on materials when buying them, so you should not see sales tax added to the total of a home re-roof. Commercial buildings are different: the Comptroller treats the full charge for nonresidential repair as taxable.
Hail and impact-resistant shingles
Hail is a regular part of spring across Dallas-Fort Worth, and it is the reason many homeowners in Prosper, Frisco and Plano ask about Class 4 shingles when they replace. Class 4 is the top rating under the UL 2218 impact test. A Class 4 shingle costs more than a standard architectural shingle, and it is still not hail-proof.
Some insurers credit impact-resistant roofs. The Texas Department of Insurance says each insurance company sets its own discount for each class of roofing, along with its own testing and paperwork rules. Before you pick a shingle, call your agent and ask what, if anything, a Class 4 roof would take off your premium. A yearly credit changes the real cost of the upgrade over the life of the roof.
Is a new roof worth the money?
A roof is not a project people take on for fun. In the same This Old House survey, 40% of homeowners replaced because of weather damage and 25% because of active leaks, and 54% were in homes 16 years or older. About 79% said the final bill came in close to what they expected.
If you plan to sell, a new roof also comes back at closing. This Old House cites the 2025 Journal of Light Construction Cost vs. Value report: a new asphalt shingle roof recovers about 68% of its cost at resale and a metal roof about 50%. A buyer's inspector flags an old roof quickly, and a recent replacement removes that conversation.
The other question is repair or replace. Scattered damage on a roof with plenty of life left can usually be repaired. Granule loss, hail bruising across every slope, or a leak that keeps coming back usually means the roof is wearing out as a whole. Our roof repair page covers how we make that call.
What goes into a quote from us
We do not publish prices, because a figure that fits one house can be far off for the house next door. Here is what a roof replacement estimate from Viva Roofing covers:
- A free inspection with photos. We inspect the shingles, flashing, vents, valleys and edges and show you the same photos we see. If the roof does not need replacing, we say so.
- A written estimate. The scope of work and your shingle line and color are in writing before anything starts, and there is no pressure to sign the day we visit.
- Decking handled openly. If we find soft or rotted boards during tear-off, we show you photos and talk it through before that wood is replaced.
- Shingle and metal options. We install architectural, Class 4 impact-resistant and metal roofs, so we can price more than one option on the same house.
- Financing, if you need it. Financing is available on approved credit through a third-party lending partner. The terms come from the lender.
Viva Roofing is a family-owned roofing company with our office in Frisco, working across Dallas-Fort Worth, San Antonio and Austin since 2021. Homeowners from Little Elm to Schertz and Cibolo get the same inspection. To find out what your own roof replacement would cost, request a free inspection.
Roof replacement cost questions
How much does a roof replacement cost in Texas?
National averages are a fair starting point: This Old House's 2026 guide puts asphalt shingles at about $5.16 per square foot installed, or about $8,772 for a typical 1,700-square-foot roof. Roof size, pitch, decking and the shingle you choose move a Texas quote above or below that.
How do I estimate the size of my roof?
Start from your floor plan and adjust for stories. This Old House estimates about 120 square feet of roof per 100 square feet of living space on a one-story home and about 60 on a two-story, at a 6/12 pitch with one-foot eaves. A roofer's measurement is the only exact number.
Why is replacing a roof so expensive?
Mostly labor. This Old House puts labor at about 65% of total project cost, and a roof is slow, physical work at height. Tear-off, disposal, decking, flashing and underlayment add to the material cost of the shingles themselves.
Is sales tax charged on a residential roof replacement in Texas?
Labor to repair or remodel residential real property is not taxable in Texas, according to the Texas Comptroller. On a lump-sum job the contractor pays tax on materials when buying them. Commercial work is treated differently and is taxable on the full charge.
Do Class 4 shingles lower insurance in Texas?
They can. The Texas Department of Insurance says each insurer sets its own discount for impact-resistant roofing and its own paperwork rules. Ask your agent what a Class 4 roof would take off your premium before you choose a shingle.
Does a 20-year-old roof need to be replaced?
Not automatically. Age matters less than condition. Widespread granule loss, hail bruising on every slope, curling shingles or a leak that keeps coming back are the usual signs that a roof is done. A free inspection with photos tells you which you have.
