| Quick Answer: There is no single number, because roof replacement cost is driven by measurable things: the roof’s size and pitch, the material you choose, how much decking has to be replaced, how many penetrations and layers of flashing are involved, and how easily crews and materials reach the roof. The only honest figure comes from measuring your specific roof. Inside & Out Roofing, Painting & Gutters gives a written, line-item estimate at no cost. Call (214) 449-4306. |
Every homeowner researching a roof replacement wants a number, and every article that offers one is guessing. Two houses on the same Denton street can differ by a wide margin because one has a steep, complex roof with several valleys and the other is a simple gable. What is genuinely useful is knowing which factors move the price, because that is what lets you read two estimates and understand why they differ, rather than assuming the cheaper one is simply the better deal.
What actually determines the price?
Cost is largely a function of measurable quantities plus labor difficulty.
- Size, measured in roofing squares rather than the square footage of your house. A large single-story footprint can carry more roof than a compact two-story.
- Pitch and complexity. Steeper roofs are slower and require more safety work, and every valley, dormer, chimney and skylight adds cut-in labor and flashing detail.
- Material. Three-tab shingles, architectural shingles, impact-resistant shingles and metal sit at very different price points, and the gap widens on a large roof.
- Decking condition. Rotted or delaminated decking is only visible once the old roof comes off, and it is replaced by the sheet.
- Flashing, vents and penetrations. Doing these properly costs more than reusing what is there, and it is where roofs leak first.
- Tear-off and layers. Removing multiple existing layers means more labor and more disposal.
- Access. Tight lots, limited driveway space, landscaping to protect and steep terrain all slow a job down.
Because most of these are quantities rather than opinions, a good estimate reads like a list of measured items, not a single lump sum.
Why do estimates from different companies vary so much?
Usually because they are not quoting the same work. One estimate may include full replacement of flashing, drip edge, pipe boots, underlayment and ridge ventilation, while another assumes reusing existing components. One may allow for a set number of decking sheets, another may leave decking as an open charge that appears later. Materials may be different grades that carry different manufacturer warranties. Disposal, permits and cleanup may be itemized in one and absent from the other.
That is why comparing bottom-line numbers is close to meaningless. Compare line items instead. Ask each company what happens if decking replacement is needed, whether the price includes new flashing and boots, which specific shingle product is being installed, and what the workmanship warranty covers. The Federal Trade Commission’s guidance on avoiding home improvement scams makes the same point about home projects generally: get it in writing, get details, and do not automatically choose the lowest bidder.
What about impact-resistant shingles and metal?
They cost more upfront, and in a hail-prone area that can be worth considering rather than dismissing. Impact-resistant shingles are built to hold up better under hail, and some insurers offer a premium discount for qualifying products. Whether a discount applies to you, and how much it is, depends entirely on your carrier and policy, so ask your agent before choosing rather than assuming.
Metal costs considerably more upfront and lasts substantially longer. Whether that pays back depends on how long you intend to own the house. We install both, along with GAF shingle systems, so the comparison can be priced side by side on your actual roof rather than argued in the abstract.
Does insurance change the cost conversation?
It changes it substantially, because the question becomes what your policy covers rather than what the total is. If a storm caused the damage, your coverage type matters: replacement cost coverage pays up to current repair cost, while actual cash value coverage subtracts depreciation for age and wear. Your deductible is your responsibility, and in Texas it is illegal for a contractor to waive it.
Whether a claim is approved, and for how much, is decided by your policy language and your adjuster. What a contractor can do is document the damage properly and give you a written scope so you have real evidence in hand. That is how we handle storm and hail insurance claims, with you remaining the one dealing with your carrier on coverage and settlement.
How can I keep the cost sensible without cutting corners?
A few things genuinely help. Time the work outside the post-storm rush if you can, when schedules are less compressed. Deal with problems while they are small, since decking rot and interior damage cost far more than the repair that would have prevented them. Bundle related exterior work, because having gutters replaced during a roof project avoids paying twice for setup and access.
What is rarely worth it is choosing the cheapest bid without understanding why it is cheapest. The savings usually come from somewhere specific: thinner materials, reused flashing, no allowance for decking, or a warranty that will not be there later.
What should a good estimate include?
A written, itemized document that names the specific products, states the measured quantities, spells out what happens if decking replacement is needed, and includes tear-off, disposal, cleanup and the workmanship warranty term. It should be something you can take away, read without anyone standing over you, and compare against another estimate line by line.
If a company will not put the scope in writing, that tells you what you need to know before any number does. Our assessments are free and produce exactly that kind of document, along with photographs of what we found on the roof.
Frequently Asked Questions
Can you give me a ballpark price over the phone?
Not an honest one. Without measuring the roof, seeing the pitch and complexity, and knowing the material, any number would be a guess that could easily be wrong in either direction. The assessment is free, and it produces a real figure.
Do you offer financing?
Ask us when we assess the roof and we will tell you what options are currently available and what the terms are. We would rather answer that accurately for your situation than describe something generic here.
Will my roof cost more because it is steep?
Usually, yes. Steeper pitches take longer, require additional safety measures, and are harder to move materials on. Complexity, meaning valleys, dormers and penetrations, tends to add more than pitch alone.
How much decking usually needs replacing?
It varies a great deal and cannot be known until the old roof is off. A good estimate states the per-sheet price up front so there is no surprise, and we show you any decking we replace.

Key takeaways
- Roof replacement cost is driven by size, pitch, complexity, material, decking and access, not by a single average figure.
- Estimates differ mostly because they quote different scopes, so compare line items rather than bottom lines.
- Ask specifically what happens if decking needs replacing, and what the per-sheet price is.
- Impact-resistant shingles cost more upfront and may qualify for an insurer discount, which varies by carrier.
- With a storm claim, your coverage type and deductible matter more than the headline price, and a contractor waiving your deductible is illegal in Texas.
- A trustworthy estimate is written, itemized, and yours to take away and compare.
