What is the average cost to replace a roof in Texas?
Most Texas roof replacements are quoted per square, meaning per 100 square feet of roof, not per square foot of house. The number that lands on your estimate is driven by six things: how much roof there is, how steep it is, how many layers have to come off, what condition the decking underneath is in, what material goes back on, and whether it is an insurance job or one you are paying for yourself. Any figure quoted before someone has been on the roof is a guess.
Roofs are priced by the square, not the square foot
A square is 100 square feet of roof surface. It is the unit the whole trade estimates in, and it is the reason a 2,000 square foot house does not have 2,000 square feet of roof: overhangs, pitch and multiple planes all add area that the floor plan does not show.
This is also why online calculators that ask for the size of your house produce a number with very little to do with your roof. A single-story ranch and a two-story house with the same floor area can differ by a third in roof area alone.
The six things that move the number
Area is the base. Everything else is a multiplier on it.
Pitch matters because a steep roof is slower and more dangerous to work on. Past a certain angle a crew cannot simply walk it, and the labor line goes up accordingly.
Layers matter because every existing layer has to come off and be hauled away. A roof carrying two layers costs more to tear off and more to dispose of than one carrying a single layer.
Decking is the variable nobody can price in advance, and the honest answer is that nobody knows what is under the shingles until the shingles are off. Soft or rotten decking has to be replaced. A good estimate says what the per-sheet rate is rather than pretending the question will not come up.
Material is the obvious one. Three-tab, architectural, Class 4 impact-resistant and standing-seam metal are four different price tiers, and the gap between them is wider than most homeowners expect.
Complexity is the last one: valleys, dormers, chimneys, skylights, low-slope sections and steep-to-flat transitions all add detail work, and detail work is where roofs leak, so it is not a place to cut.
An insurance job is priced differently
If the roof is being replaced because of storm damage, the price is not really a negotiation between you and a roofer. The insurer writes a scope based on what the adjuster documents, and the settlement is built from that scope.
What you pay out of pocket in that case is your deductible, not the cost of the roof. This is the single biggest reason two neighbors with identical houses can pay wildly different amounts for the same work.
It also means the useful work happens before the adjuster arrives, not after the estimate. Damage that is not documented is not in the scope, and what is not in the scope is not paid for.
Why we do not publish a price per square
A published rate would be either meaningless or misleading. It cannot know your pitch, your layers, your decking or your material, and the roofs it would be wrong about are exactly the ones a homeowner most needs a real number for.
What we do instead is inspect the roof for free and put the scope in writing, so what you are comparing between contractors is the same work rather than two numbers with different things hidden inside them.

Can you quote a roof over the phone?
Not honestly. Area, pitch, layers and decking condition all change the number, and none of them can be established from a phone call. We can tell you what the process looks like and book a free inspection.
What is a square?
100 square feet of roof surface. It is the unit roofing is estimated in, and it is measured on the roof rather than on the floor plan.
Why do estimates from different roofers vary so much?
Usually because they are not for the same work. Different underlayment, different flashing treatment, different assumptions about decking replacement and different disposal all land in the same-looking total. Comparing written scopes rather than totals is the only way to see it.
Does a more expensive shingle actually last longer?
Generally yes within a manufacturer range, and Class 4 impact-resistant shingles are made specifically for hail regions. But installation quality decides more roofs than material choice does. A premium shingle installed badly still fails at the flashing.
