Roofing is quoted by the square, which is 100 square feet of roof surface. Your price moves with roof area, pitch, material, how many old layers come off, and decking condition. Coastal addresses add corrosion resistant flashing and fasteners. David measures your roof and sends a written line item price within 48 hours.
How is a roof actually priced in the Rio Grande Valley?
Roofers here quote by the square. One square covers 100 square feet of roof surface.
A 1,800 square foot single story house usually measures closer to 20 or 24 squares. Pitch and overhangs make the roof larger than the floor plan.
The square sets the base, but it is not the whole estimate. Tear-off, decking replacement, flashing and ventilation are separate line items with their own units. An estimate that shows one number for everything hides where your money goes.
Ask for the estimate broken out by line. You cannot compare two roofs until you can see which parts each contractor priced.
| Line item | Unit it is quoted in | Why that unit is used |
|---|---|---|
| Roofing material and labor | Per square, or 100 square feet | Pitch and overhang make roof area larger than the floor area |
| Tear-off of the old roof | Per square, per layer | A second layer doubles the dump weight and the labor hours |
| Decking replacement | Per sheet of plywood or OSB | Nobody knows the real count until the old roof is off |
| Drip edge, flashing and valley metal | Per linear foot | A cut-up roof has far more edge than a plain gable of the same area |
| Pipe boots, vents and turbines | Each | The count is fixed and visible from the ground before work starts |
| Ridge vent and intake | Per linear foot of ridge | Airflow is sized to the attic, not scaled off the roof price |
| Permit and inspection handling | Per job | Rules change by city, so the work is a task, not a percentage |
What moves the price of a roof, and how much does each one move it?
Two houses on the same street can carry very different roof prices. The reasons are measurable, and a good estimator names them out loud before quoting.
The table below ranks those variables by how hard each one pushes on the total. High means the variable can change a large share of the price. Low means it lands as a line item you barely notice.
Use it as a checklist on your own house. Ask which of these apply to your roof and by how much. If that answer is vague, the number behind it is also vague.
| Variable | Weight on the total | What it does to your quote |
|---|---|---|
| Squares of roof area | High | Sets the base. Every other cost on the job rides on top of it |
| Material choice | High | Standing seam metal sits well above architectural shingle per square |
| Pitch and walkability | High | A steep roof needs staging, slows the crew and raises the labor line |
| Layers to tear off | Medium to high | Each extra layer adds labor, disposal weight and a day of exposure |
| Decking condition | Medium to high | Unknown until tear-off. Get a per sheet allowance in writing first |
| Roof complexity | Medium | Valleys, dormers and hips add cutting, waste and linear feet of flashing |
| Coastal corrosion package | Medium | Coated or stainless fasteners and heavier flashing near the bay |
| Second story or hard access | Medium | Longer ladders, more staging and slower material handling all day |
| Ventilation corrections | Low to medium | Adding ridge vent or intake is small next to a roof that fails early |
| Distance from Rio Grande City | Low | Travel follows a zone rule you are told up front, not a percentage |
| Color and profile choice | Low | Mostly a stock and lead time question rather than a cost question |
Does metal really cost more than shingle in the Valley?
Up front, yes. Standing seam metal costs more per square than architectural shingle at every supply house in the Valley. That gap is real and it is large.
The comparison changes when you divide by years of service. Architectural shingle lasts 18 to 25 years inland in this heat. Standing seam metal runs 40 to 50 years.
So metal is more expensive per job and often cheaper per year in the house. Exposed fastener metal sits between the two, and its screws and washers need changing around year 12.
| Material | Cost per square, relative | Service life here | Cost per year, relative |
|---|---|---|---|
| Three tab shingle | Lowest | Shortest of the common options in 160 degree surface heat | Highest |
| Architectural shingle | Low | 18 to 25 years inland | Medium |
| Exposed fastener metal | Medium | 25 to 30 years, with a screw change around year 12 | Low to medium |
| Standing seam metal | High | 40 to 50 years | Low |
| Clay or concrete tile | Highest | 50 years or more where the framing already carries it | Low, if the structure allows it |
Why does a coastal address in Cameron or Willacy County change the quote?
Salt air is the difference. It corrodes fasteners, flashing and valley metal years before the roof surface itself wears out. The roof looks fine from the street while the metal holding it down fails.
So a coastal roof gets specified differently. Fasteners, drip edge and flashing move to corrosion resistant material. That choice appears as its own line in an honest estimate.
There is a second layer near the coast. The Texas Department of Insurance requires a windstorm inspection for a home to remain insurable through TWIA. Whether your home falls inside that requirement is verified by address.
We check your address before we quote. A roof installed without the inspection your address needs can cost you a policy. That is a far larger problem than any roof line item.
- Fasteners and flashing specified for salt air instead of standard galvanized
- Edge and eave detail tightened, because wind uplift starts at the perimeter
- Windstorm inspection scheduled as part of the job, not left to you afterward
- Documentation kept with dated photos, so your carrier sees what was installed
What does the age of Valley housing do to a roof price?
Starr County housing is mostly owner occupied, about 72 percent of it. The median home here was built in 1987.
A house from the late eighties is usually on its second or third roof. Second layers, tired decking and undersized attic ventilation are common findings once the crew opens it up.
Owner occupied also means the bill is personal. The median household income here is near 38,000 dollars a year.
A surprise line item after tear-off is a serious problem for a family. That is exactly why the decking allowance belongs in writing before anybody starts.
What is usually missing from a cheap roofing estimate?
A low number is very often a short scope. The savings come from line items that were never written down, and they come back later as change orders.
Read any estimate against the list below before you compare it with another one. Each missing item is money that moves from the quote into your pocket at the worst moment.
- A decking allowance priced per sheet, so a rotten deck is not a renegotiation
- Tear-off and disposal of every existing layer, stated layer by layer
- New flashing, drip edge and pipe boots instead of reusing the old ones
- Underlayment named by type, not just the word underlayment on a line
- Attic ventilation measured and corrected, rather than assumed to be fine
- Permit handling for your city, and the windstorm inspection if your address needs one
- Daily magnet sweep and debris haul-off written into the scope
- A workmanship warranty on paper, with a term in years and a name on it
- Who is actually on the roof: the company crew or a subcontractor nobody named
What should you ask so two roof estimates are comparable?
Two estimates are only comparable when they describe the same roof. Most of the time they do not, and the cheaper one is simply smaller.
Ask every contractor the same questions and ask for the answers in writing. Differences that looked like price almost always turn out to be scope.
- How many squares did you measure, and did you measure the roof or estimate from the street?
- How many layers are coming off, and is disposal of all of them included?
- What is the decking allowance per sheet, and what happens if we go past it?
- What underlayment goes down, and what protects the valleys?
- Is every piece of flashing new, including chimney and wall lines?
- What is the workmanship warranty term, and do I get it on paper at handover?
- Who pulls the permit, and does my address need a windstorm inspection?
- What is your start date, and what happens to it if weather moves us?
When do you get a real number for your roof?
Nobody can price your roof over the phone, and a contractor who tries is guessing. Squares, pitch, layers and decking are all found on the roof, not on a call.
A phone number gets corrected upward once the crew arrives. That correction is the most common complaint homeowners in the Valley have about roofing work.
David walks the roof himself. He measures it, photographs every problem and checks the decking from inside the attic. The visit takes about 45 minutes.
You get a line item price in writing within 48 hours of that visit. It shows squares, material, tear-off, the decking allowance and cleanup. Hold it next to any other bid and the difference shows.

Questions we get02
Before you call
Can you price my roof from satellite images?
We can measure roof area from aerial imagery, and we use it to check our own numbers. It cannot tell us about layers, decking condition or flashing. Those three are where roof estimates go wrong, so David still walks the roof before any price goes out.
Is a roof cheaper in the off season?
Scheduling is easier in late fall and winter, and lead times on material are shorter. The scope of work does not change with the calendar, so the line items stay the same. What you gain in the slow season is a start date you can count on.
Why does the decking allowance matter so much?
Because nobody can see the decking until the old roof is off. An estimate without an allowance leaves that cost open, and you find out on day two. With a per sheet number agreed in writing, a bad deck becomes arithmetic instead of an argument.
Does my insurance claim decide what the roof costs?
It decides what your carrier pays, not what the work costs. The scope of repair is settled between you, your adjuster and us, with dated photos of the damage. We give you a written scope that matches the roof, and you see any difference before signing.
Do you charge for the estimate?
No. The roof walk, the measurements, the attic check and the written line item estimate are free. You get the document within 48 hours whether you hire us or not.
