The Answer
What a roof costs in Round Rock, per square
The published planning ranges
A square is one hundred square feet of roof surface. These are the ranges The Roof Shepherd publishes for Central Texas, approved September 2026 and valid until December 2026. They are planning ranges, not quotes, and they are the same ranges our own assistant gives.
| Roof type | Planning range, per square installed |
|---|---|
| Architectural asphalt shingle | $545 to $670 |
| Class 3 impact resistant | $545 to $670 |
| Class 4 impact resistant | $600 to $735 |
| Standing seam metal | $1,500 to $2,200 |
Two roofs of the same size in Round Rock can land at opposite ends of that range. The next section is why.
The Variables
What moves the price on a Round Rock roof
The five things that actually change the number
| What changes | What it does to the price |
|---|---|
| Roof pitch from 7/12 to 12/12 | adds about $20 to $45 a square |
| A second story | adds about $20 a square |
| A cut up roof with many valleys and facets | adds about $25 a square |
| Decking replaced beyond the first two sheets | $80 a sheet installed |
| Solar panels detached and reset | $255 to $545 a panel |
Decking is the one nobody can price from the driveway. The old roof has to come off before anyone can see whether the wood underneath is sound, which is why an honest estimate names a decking allowance and a per sheet price rather than pretending to know.
Worked Example
A worked example, and the assumption behind it
One roof, start to finish
The assumption, stated so you can check it: a single story home with about 2,400 square feet of living space, a common 6/12 pitch, and ordinary overhangs, works out at roughly 26 squares of roof. A two story home with the same living space has about half the footprint and therefore about half the roof.
At 26 squares, architectural asphalt at $545 to $670 a square is $14,170 to $17,420 before anything below. Class 4 impact resistant on the same roof is $15,600 to $19,110. If four sheets of decking turn out to be soft, add $160, because the first two are included. If the pitch is 8/12 rather than 6/12, add $520 to $1,170.
That is arithmetic on published ranges, not a quote for your house. Your roof gets measured and photographed before anyone gives you a number.
Local Detail
What is specific to Round Rock
The local part of the number
NOAA has recorded 110 hail events within ten miles of Round Rock since 2018, the largest stone measuring 4 inches. That history is the argument for asking about Class 4 impact resistant shingles here rather than defaulting to architectural.
The storms behind that number, most recent significant first:
- September 24, 2023, 4.0 inch
- September 24, 2023, 3.75 inch
- September 24, 2023, 3.5 inch
If your roof was on the house for any of those dates and has not been looked at since, that is the first thing to establish, before price.
Permit: Round Rock does not require a permit for a residential re-roof, which is unusual and worth knowing before a contractor bills you for one.
Half the homes in Round Rock were built before 2001. A roof put on with the house is at or past the age where the question stops being repair and starts being replacement, so roof age is worth establishing before you price anything.

Questions
Five questions homeowners ask us about cost
Why is the price given as a range instead of a number?
Because the two things that move it most, the pitch of your roof and what the decking looks like once the old roof is off, cannot be known from the street. A firm number before anyone has been on the roof is a guess dressed up as a quote.
What is a square?
One hundred square feet of roof surface. Roofers price in squares, not in the square footage of your house, and the two are never the same number because of pitch and overhangs.
Is Class 4 worth the extra money here?
That depends on your hail history and your insurer. Class 4 costs about $55 to $65 more a square than architectural, and many Texas carriers discount the premium for it. Ask your carrier what the discount is on your policy before deciding, because it varies and we cannot promise it.
Does insurance change what I pay?
It changes who pays, not what the work costs. What your policy covers is a decision your insurer makes under your policy, and no roofer can promise that outcome. Texas law requires you to pay your deductible.
What should make me walk away from a quote?
A price given without anyone getting on the roof, pressure to sign the day of the knock, a refusal to itemise, and anyone offering to cover your deductible, which is a criminal offence in Texas.
