If you've started calling around Lewisville for a roof replacement quote, you've probably noticed the numbers don't agree with each other. That's not necessarily anyone lying to you — roof pricing genuinely swings based on size, pitch, material, and what a crew finds once they pull the old shingles off. Below is a realistic breakdown of what roof replacement costs in the Lewisville and Denton County market, what moves that number, and how to read a quote so you're comparing apples to apples instead of guessing. Alpine Exteriors serves Lewisville as part of our North Texas service area, and the ranges here reflect what we actually see on jobs in this market, not a lowball number designed to get a foot in the door.
For a typical Lewisville single-family home — roughly 1,800 to 2,800 square feet under roof once you account for pitch, hips, valleys, and waste — a full asphalt shingle tear-off and replacement generally falls between $9,000 and $19,000 installed. That's a wide range on purpose, because a simple single-story hip roof and a steep two-story roof with multiple dormers and valleys are not the same job even at identical square footage.
Priced by the square (one roofing square equals 100 square feet of finished roof area), builder-grade 3-tab and entry-level architectural shingles typically run $350–$450 per square installed in this market. Mid-grade dimensional (architectural) shingles, which is what most Lewisville homeowners end up choosing, run closer to $425–$550 per square. Class 4 impact-resistant shingles — worth serious consideration in a hail corridor like this one — usually add another $75–$150 per square over a standard architectural shingle, sometimes offset partly by an insurance premium discount. Standing seam metal roofing is a different tier entirely, generally $900–$1,400 per square installed, which puts a full metal re-roof on an average home in the $22,000–$45,000+ range. Tile is uncommon here and usually not cost-effective on typical Denton County framing, so we won't spend much time on it.
What actually sets Lewisville pricing apart from a national average isn't exotic — it's a combination of DFW-area labor and material costs, a housing stock split between older single-story homes near Old Town and Lake Lewisville and newer two-story construction with steeper, more complex rooflines further out, and City of Lewisville permitting requirements that add a modest but real line item to every job. None of that is dramatic on its own, but together it's why generic “national average” price guides rarely match what you'll actually be quoted here.
A handful of variables account for most of the spread between the low end and high end of any quote:
A complete Lewisville roofing quote should spell out, in writing, more than just “shingles and labor.” At minimum, look for:
If a quote is missing several of these, it's not necessarily a bad contractor — but it is an incomplete quote, and incomplete quotes are where change orders come from later.
The best defense against a bad roofing experience is comparing quotes on identical scope, not just the bottom-line number. A few practical steps:
Lewisville and the rest of Denton County are not part of the coastal Texas windstorm insurance pool (TWIA) — that program applies to counties along the Gulf Coast, not here. Instead, wind and hail damage in this area is typically covered under a standard homeowner's policy, often with a separate wind/hail deductible. That deductible matters a lot: many North Texas insurers have shifted from a flat-dollar wind/hail deductible to a percentage-based one, commonly 1% to 3% of your home's dwelling coverage. On a $350,000 dwelling coverage limit, a 2% deductible is $7,000 out of pocket before insurance pays anything — a very different number than the flat $1,000 deductible many homeowners assume they still have. It's worth pulling out your actual policy declarations page and checking this before you assume a claim will cover most of the cost.
Also worth knowing: some insurers have moved toward settling older roofs (commonly those over 10–15 years) on an actual cash value (ACV) basis rather than full replacement cost value (RCV), which means depreciation gets subtracted from the payout regardless of the damage. If your roof is in that age range, ask your agent directly which settlement type applies before you assume a claim will fully cover a new roof.
If you suspect hail or wind damage, an independent inspection before you file a claim is worth the time — it tells you whether there's a legitimate claim to file at all, rather than starting the claims clock on damage that may not qualify. Be cautious with public adjusters who solicit door-to-door after storms; they typically take a percentage of your payout, which can be reasonable in a complex claim but isn't necessary for a straightforward one.
For homeowners paying out of pocket or covering a deductible, financing is common in this market — many roofing contractors, including Alpine Exteriors, offer financing plans, and a home equity line or personal loan are the other typical routes. Compare the total cost including interest, not just the monthly payment, before committing.
Most single-family homes fall between roughly $9,000 and $19,000 for a full asphalt shingle replacement, with the exact number driven mainly by roof size, pitch, material grade, and how much decking needs replacing. Metal roofing and larger or more complex homes run higher.
Often yes, but the coverage depends on your specific policy, your wind/hail deductible (which may be percentage-based rather than a flat dollar amount), and your roof's age. An adjuster inspection determines the actual payout — no contractor can guarantee a coverage outcome in advance.
A straightforward asphalt shingle tear-off and replacement on an average Lewisville home typically takes one to three days, weather permitting. Steep or complex rooflines, extensive decking repair, or metal roofing all extend that timeline.
It's worth considering given how frequently this area sees hail. Class 4 impact-resistant shingles cost more upfront but may qualify you for an insurance premium discount, and they hold up better to the kind of hail events that are common in North Texas. Whether the math works out depends on your specific policy discount and how long you plan to stay in the home.
Cost ranges are useful for planning, but the only way to get a real number for your specific roof is a physical inspection.
