If you own a home in Gretna, a new roof is one of the largest investments you will make in it, so “how much does roof replacement cost?” is usually the first question. In 2026, a typical Gretna roof replacement runs between $12,500 and $29,000, with most homes landing near $18,000. Below, we break that number down by roof size, material, and the local factors that move the price up or down.
Please note: Every price on this page is an estimate based on what we typically run into on Gretna roofs. It is not a quote or a price guarantee. Material costs, roof conditions, and project details vary, and all pricing is subject to change. The only way to know your exact cost is a free, in-person inspection and written estimate.
Roofing contractors price jobs by the “square,” which equals 100 square feet of roof surface. Most Gretna homes, from the established blocks near downtown Gretna to the newer subdivisions off Highway 6 and the I-80 corridor, have between 22 and 36 squares once pitch and overhangs are included. Understanding squares, materials, and complexity is the key to knowing what a fair quote looks like.
Average Cost by Roof Size
How much roof you have is the biggest driver of your price. The table below shows typical installed costs for an architectural asphalt shingle roof in Gretna, grouped by home size. These ranges include tear-off of one existing layer, new underlayment, and standard installation.
Ranges reflect what we typically see and are subject to change. Not a price guarantee.
A steep or cut-up roof on a smaller home can cost more than a simple roof on a larger one. Square footage is the starting point, not the whole story.
Cost by Roofing Material
Material choice is the second major factor. Asphalt shingles are the most common choice in Gretna for their balance of cost and durability, while metal and premium synthetic options serve homeowners who want maximum longevity. Here is how the common options compare.
For most Gretna homeowners, architectural asphalt shinglesare the sweet spot and a big step up from the builder-grade shingles many newer subdivisions started with. Because Gretna sits in Sarpy County's hail corridor and its open lots leave roofs fully exposed, upgrading to Class 4 impact-resistant shingles is worth considering and may lower your homeowners insurance premium. For higher-end homes, we also install premium CertainTeed, Brava, and DaVinci product lines.
Factors That Affect the Price
Two homes of identical size can receive very different quotes. These are the factors that move your roof replacement cost up or down:
- Roof pitch (steepness): Steeper roofs require more safety equipment and labor, raising the price.
- Roofline complexity: Many newer Gretna two-stories have multiple gables, hips, and valleys, which add labor and flashing work.
- Decking condition: Soft or damaged sheathing found during tear-off must be replaced for a sound roof, especially on older homes near downtown.
- HOA requirements: Some neighborhoods require specific shingle styles or colors, which can narrow product options.
- Skylights, chimneys, and dormers: Each penetration needs custom flashing and detail work.
- Ventilation upgrades: Correcting undersized attic ventilation protects the new roof and your warranty.
- Material and warranty tier: Premium shingles, metal, and extended warranties increase upfront cost.
This is why a written, itemized quote after an in-person inspection is always more accurate than an online calculator. We walk your roof, measure it, and account for each of these factors before giving you a number.
Storm Damage? How Insurance Can Help
Gretna sits in an active storm corridor in western Sarpy County, where spring and summer storms regularly bring hail and straight-line winds across open terrain. If your roof was damaged by hail or wind, your homeowners insurance may cover the replacement — you are typically only responsible for your deductible.
Hail damage is often invisible from the ground, so the process starts with a professional inspection. We work with insurance companies regularly and help homeowners with insurance claims and adjusters. If you suspect damage, learn more about our storm damage roof repair or hail damage roof repair.

How much does a new roof cost in Gretna in 2026?
Based on the projects we typically see, most Gretna homeowners pay between $12,500 and $29,000 for a full roof replacement in 2026, with a typical architectural asphalt shingle roof landing around $18,000. These are general ranges, not a price guarantee. Your final price depends on roof size, the material you choose, pitch and complexity, and current material costs, all of which are subject to change.
How much does it cost to replace a 2,500 square foot roof in Gretna?
Many Gretna homes are ranch and two-story builds in the 2,000 to 3,000 square foot range, which usually works out to about 25 to 34 roofing squares once pitch and overhangs are included. At typical installed rates of $400 to $600 per square, a standard architectural shingle replacement typically falls roughly between $12,000 and $20,000, though every roof is different and pricing is subject to change. Upgrading to impact-resistant shingles, designer shingles, or metal increases that figure.
Why do newer Gretna homes sometimes need a roof sooner than expected?
Gretna is one of the fastest-growing towns in the Omaha metro, and many of the newer subdivisions off Highway 6 and the I-80 corridor were built with builder-grade shingles. Those neighborhoods also sit on open ground with few mature trees, so roofs take the full force of hail and straight-line winds. As a result, we regularly replace Gretna roofs that are only 10 to 15 years old.
Do HOAs in Gretna affect the cost of a new roof?
They can. Many newer Gretna neighborhoods have HOA architectural guidelines on shingle style and color, and some require a specific product line. Meeting those standards can affect price. We work with Sarpy County HOAs regularly and can help you choose an approved shingle before work begins.
Will insurance pay for my roof replacement in Gretna?
If your roof was damaged by hail or wind, your homeowners policy may cover the replacement minus your deductible. We work with insurance companies regularly and help Gretna homeowners with insurance claims and adjusters.
