Houston Roof Replacement Cost Calculator

A roof replacement on a typical Houston home costs $8,000 to $20,000. The range is wide because a 1,600 square foot one-story roof and a 4,000 square foot two-story with steep pitches are genuinely different jobs.

Our estimator measures your roof from satellite imagery, not an average one. No salesperson, and it works at two in the morning.

Asphalt shingle

$350–650/square

Metal roofing

$700–1,200/square

Decking, if needed

$75/sheet

A square is 100 square feet of roof surface, not floor area, so it is always more than the footprint of the house. A typical Houston home is roughly 20 to 30 squares.

The variables

Six Things That Move a Roof Replacement Cost

Why one Houston roof costs $9,000 and the one next door costs $19,000, and what to ask any contractor about each.

Roof size and pitch

The biggest single variable

Size is measured in squares of 100 square feet, and it is roof surface rather than floor area: a 2,000 sq ft house does not have a 2,000 sq ft roof. Pitch matters as much. Anything above 6/12 slows the crew and brings in fall-protection equipment, and above 10/12 is quoted separately.

Ask: how many squares did you measure? If two contractors disagree on the size of your roof, one of them is wrong.

Material

Where the price tiers come from

Asphalt runs $350 to $650 a square installed, depending on the shingle and system; metal runs $700 to $1,200. Within asphalt, the spread comes from the shingle line, the warranty tier registered, and the components that go underneath.

Ask: what goes under the shingle? Two quotes naming the same shingle can still be very different roofs.

Complexity

Facets, dormers, valleys and penetrations

A simple gable roof is quick. Multiple levels, dormers, skylights, chimneys and long valleys all add labor, material and cut waste. Every penetration is a place water can get in, so each one is detailed properly rather than sealed over.

Complexity is why an online estimate is a range. It reads the shape of the roof, not what is on it.

Layers coming off

One tear-off or two

Two layers means twice the removal and twice the disposal. It is common on older Houston homes where a previous contractor laid over instead of tearing off. It is also why we never lay over: it makes the next replacement more expensive for whoever comes after.

The estimator cannot see this. It is one of the first things we check on site.

Decking

The line that grows a quote after signing

Soft or rotten sheets only show once the old roof is off. Our packages include up to five sheets; beyond that it is $75 a sheet during a replacement, photographed and shown to you before we replace anything.

Ask: what is your per-sheet price? It varies enormously, and it is the line item nobody thinks to check.

Labor, permits and access

Local, and often overlooked

Permit requirements vary across the Houston metro by jurisdiction. Access matters too: a house with no driveway space for a dumpster, or landscaping that needs protecting, takes longer.

A contractor who asks you to pull the permit yourself is worth a second question.

Offsetting the cost

The Class 4 Insurance Discount, Accurately

There is a great deal of confusion about this, including from roofers. Here is what the Texas Department of Insurance actually says, in its own words rather than ours.

“A Class 4 roof covering would receive the highest premium credit. The amount of discount for each class of roofing material is established by the insurance company on a company-by-company basis.”

Class 4 = highestTDI states Class 4 receives the highest premium credit of the four classes.
Your carrier sets itThe amount, the test criteria and the paperwork are decided company by company.
Never automaticYou have to request it and submit the documentation.

What we will not tell you is a percentage. You will find roofing sites quoting 20%, 35%, even 70%. There is no statewide figure, because TDI is explicit that each company sets its own, so any roofer promising you a specific saving is guessing.

What we can tell you: Class 4 earns the largest credit available, your carrier decides how large, and you have to ask. We provide the UL 2218 documentation with every impact-rated installation. The number is a conversation with your agent, ideally before you choose a shingle rather than after.

The question nobody tells you to ask

Some carriers attach a cosmetic damage exclusion to the impact-resistant discount. Under that arrangement, hail that dents shingles without functionally damaging them may not be covered at all: you take the lower premium and give up cosmetic hail claims.

That may be a perfectly good trade on a Class 4 roof, which is built not to be functionally damaged in the first place. But it should be a decision you made, not one you discovered after a storm.

Ask your agent: is any endorsement required to receive the credit, and what does it exclude?

Ask your carrier four things: whether they offer an impact-resistant credit at all, what it is for a UL 2218 Class 4 roof, whether an endorsement is required to get it, and when it takes effect. Some apply it at renewal rather than immediately.

Common questions

Roof Replacement Cost Questions, Answered

How much does a roof replacement cost in Houston?

A typical Houston home runs $8,000 to $20,000. Asphalt shingle systems cost $350 to $650 per square installed, depending on the shingle line and warranty tier, and metal $700 to $1,200 per square.

A typical Houston home is roughly 20 to 30 squares. At $400 a square, a 25-square roof works out to about $10,000.

How accurate is the online estimate?

It is accurate on what it can measure from satellite imagery: roof area, facets, pitch and ridge lengths. That is most of what drives the price.

It cannot see decking condition, how many layers are already on, or whether the ventilation is adequate. That is why it returns a range rather than a price, and why the free on-site inspection produces the firm written number.

Why do quotes vary so much between contractors?

Usually because they are not quoting the same job: a different shingle grade, warranty tier, underlayment, ventilation, and treatment of decking once the roof is open.

A single line reading “tear off and replace roof” commits a contractor to almost nothing. Compare the itemized detail rather than the totals, and ask each one what they charge per sheet of decking.

What is a roofing square, and how many will my roof need?

A square is 100 square feet of roof surface, not floor area, so it is always larger than the footprint of the house. Pitch adds to it too: a steep roof has more surface than a shallow one over the same rooms.

A typical Houston home is roughly 20 to 30 squares.

What happens if you find rotten decking?

The first five sheets are free. Beyond that it is $75 a sheet during a replacement, photographed and shown to you before we replace anything, so it never appears as a surprise on the invoice.

Ask every contractor this before you sign. Per-sheet prices vary a great deal, and most include no free sheets at all.

Does the price change after you inspect?

The online figure is a range; the written estimate after inspection is a price. Once that is signed, the only thing that changes it is decking we could not see until the old roof came off, and you approve that with a photograph in front of you.

Is it cheaper to repair than replace?

In the short term, almost always. Repairs start at $195, with most single-issue repairs between $350 and $900.

The honest test is whether the repair buys you years or months. On a roof already fifteen-plus years old, a substantial repair is often money spent twice. We credit up to 25% of a repair cost against a later replacement we carry out. See repair prices.

Can I finance a roof replacement?

Yes, through the Wells Fargo Home Projects credit card issued by Wells Fargo Bank, N.A., and through Service Finance Company, a Truist company. Promotional 0% APR is available to qualified applicants, subject to credit approval.

Compare financing against a HELOC and the alternatives.
