Instant roof replacement estimator · Houston's roof cost calculator
A typical Houston home runs $8,000 to $20,000. That range is wide because a 1,600 square foot single-storey roof and a 4,000 square foot two-storey with steep pitches are genuinely different jobs.
Houston Roof Replacement Cost Calculator. The estimator below measures your roof rather than an average one. No phone call, no salesperson, and it works at two in the morning.
Asphalt shingle
$325–650/square
Metal roofing
$700–1,200/square
Decking, if needed
$90/sheet
A square is 100 square feet of roof surface, not floor area — always more than the footprint of the house. A typical Houston home is roughly 20 to 30 squares.
Instant estimate
Measured from satellite imagery. It cannot see decking condition, existing layers or ventilation, so the figure is a range — the free inspection gives you a written price.
The variables
Why one Houston roof costs $9,000 and the one next door costs $19,000 — and what to ask about each. Houston Roof Replacement Cost Calculator.
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 any quote how many squares they measured. If two contractors disagree on the size of your roof, one of them is wrong.
Where the tiers come from
Asphalt runs $325–$650 a square installed depending on the shingle and system, metal $700–$1,200. Within asphalt the spread comes from the shingle line, the warranty tier registered, and which components go underneath.
The shingle is one of eight components. Two quotes naming the same shingle can still be very different roofs.
Facets, dormers, valleys and penetrations
A simple gable roof is quick. Multiple levels, dormers, turrets, skylights, chimneys and long valleys all add labour, 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 but not what is on it.
One tear-off or two
Two layers is twice the removal and twice the disposal, and it is common on older Houston homes where a previous contractor laid over rather than 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.
The one that grows a quote after signing
Soft or rotten sheets are only visible once the old roof is off. Our packages include up to five sheets; beyond that it is $90 a sheet during a replacement, photographed and shown to you before we replace anything.
Ask every contractor their per-sheet price before you sign. It varies enormously and it is the line item nobody thinks to check.
Local, and often overlooked
Permit requirements vary across the Houston metro by jurisdiction. Access matters too — a house with no driveway access for a dumpster, or landscaping that needs protecting, takes longer.
A contractor who asks you to pull the permit yourself is worth a question.
Offsetting the cost
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.”
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, or worse.
What we can tell you is that Class 4 attracts the largest credit available, that your carrier decides how large, and that you have to ask. We provide the UL 2218 documentation with any 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 rather than 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 any endorsement is required to get it, and when it takes effect — some apply it at renewal rather than immediately.

Common questions
It is accurate on the things it can measure — roof area, facets, pitch and ridge lengths, taken from satellite imagery. 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 is what produces a firm written number.
Usually because they are not quoting the same job. Different shingle grade, different warranty tier, different underlayment, different ventilation, and different 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 itemised detail rather than the totals — and ask each one what they charge per sheet of decking.
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. At $400 a square, a 25-square roof works out at about $10,000.
The first five sheets are free. Beyond that it is $90 a sheet during a replacement — photographed and shown to you before we replace anything, so it never appears as a surprise on the invoice.
Worth asking every contractor this before you sign. Per-sheet prices vary a great deal, and most include no free sheets at all.
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.
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 is buying 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. Repair prices in full
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.
The estimator gives you a range in about a minute. The free inspection gives you a written price — and sometimes the answer that your roof does not need replacing yet. Houston Roof Replacement Cost Calculator.
