“How much will a new roof actually cost me?” is usually the first question homeowners ask, and it’s also the hardest one to answer with a single number. Roofing costs vary widely depending on your roof’s size, pitch, material choice, and the condition of what’s underneath the shingles. At Lotus Roof Restoration, we provide detailed, written estimates for every new roof installation in Plano and across DFW, and this guide breaks down the factors that actually move the price up or down, so you can go into your own estimate with realistic expectations.
Roof size and complexity
The single biggest driver of cost is simply how much roof you have. Contractors typically price by the square, a roofing term for 100 square feet of roof area, so a larger home naturally costs more to re-roof than a smaller one, all else being equal. But size isn’t the only geometry factor — a roof with a steep pitch, multiple valleys, dormers, or a complicated roofline takes longer to install and requires more safety equipment and material cutting than a simple, low-slope rectangular roof. Two homes with identical square footage can have meaningfully different roofing costs purely because of roofline complexity.
Material choice
Material is the next major lever, and the range here is wide. Standard three-tab asphalt shingles sit at the more affordable end, while architectural (dimensional) asphalt shingles cost more but offer better wind resistance and a longer expected lifespan, which is why they’ve become the more common choice for homeowners planning to stay in their property long-term. Beyond asphalt, materials like metal roofing sit at a noticeably higher price point upfront, but can outlast asphalt shingles by decades, which changes the cost comparison significantly once you factor in a longer ownership timeline. We cover this trade-off in more depth in our guide to choosing the right roofing material for North Texas homes.
Decking and structural repairs
What’s happening underneath your existing shingles has a real impact on final cost, and it’s one of the harder factors to estimate accurately before work begins. If your roof deck has water damage, rot, or sagging sections, that plywood or OSB sheathing needs to be replaced before new shingles go on, and that’s additional material and labor beyond the base roofing estimate. A thorough roof inspection before your project starts helps flag likely decking issues in advance, which reduces the chance of a significant surprise once tear-off begins and the crew can see the deck directly.
Removal of the old roof
Tearing off an existing roof before installing a new one adds cost compared to installing over an existing layer, which some contractors offer for asphalt shingle roofs with only one existing layer already in place. While installing over an existing layer can save some upfront cost, we generally recommend a full tear-off for most projects, since it lets us properly inspect and repair the decking underneath and typically results in a longer-lasting, better-performing roof. If a lower upfront cost is the priority, it’s worth having an honest conversation about the trade-offs rather than assuming the cheaper option is automatically the better value.
Storm damage and insurance claims
If your roof replacement is being driven by storm or hail damage, your actual out-of-pocket cost may look very different from a self-pay project, since insurance may cover some or all of the replacement cost depending on your policy and deductible. In these cases, the estimate we provide is built to align with what an insurance adjuster expects to see, with clear documentation supporting the scope of work. It’s worth understanding your deductible amount and policy coverage before assuming a storm-related replacement will be fully out of pocket or fully covered — the real number is usually somewhere in between, depending on your specific policy.
Labor, warranties, and contractor quality
It’s tempting to treat roofing quotes as apples-to-apples and simply pick the lowest number, but labor quality and warranty coverage are part of what you’re actually paying for. A lower quote sometimes reflects rushed installation, cut corners on flashing details, or a lack of real workmanship warranty backing the work. Review our 10-year roofing workmanship warranty and the written terms for your proposed work. Some enhanced manufacturer warranties also include installation-error coverage; GAF’s warranty comparison illustrates why the actual documents matter.

Getting an accurate estimate for your home
Because so many factors affect the final number, the only reliable way to know what your specific roof will cost is a direct, on-site estimate rather than a generic online calculator or a per-square-foot rule of thumb pulled from a different climate or market. Our estimators measure your roof directly, evaluate decking condition where possible, and walk you through material options at different price points, so you understand exactly what’s driving your number and where there’s room to adjust based on your budget and priorities.
If you’re planning a new roof in Plano, Frisco, McKinney, or anywhere across our DFW service area, the best next step is a free roof inspection followed by a clear, written estimate — no generic square-footage guesses, no pressure to decide on the spot.
