The cost of a new roof in Minnesota varies widely depending on factors like the size and complexity of your home, the materials you choose, and the condition of your existing roof. Additional elements—such as ventilation, insulation, and necessary repairs—can also impact the final price. Because every home is different, getting a professional inspection is the best way to determine an accurate estimate.
Is your roof past its prime, leaking, or showing storm damage? We get it! Between Minnesota’s rainy, snowy weather and the wear and tear of time, your home’s roofing system eventually needs replacement.
Since roofing is so important in protecting your house’s value and performance, it’s not worth delaying its replacement. But we realize you want to be practical with your budget too. Let’s take an honest, realistic look at how roof replacement costs are calculated—so you’ll know what to expect.
Different Factors That Affect Your Roof Replacement Estimate
Once you receive a proposal for your new roof, give it a once-over. You’ll see different elements noted on your paperwork—and of course, you can ask our team for more details anytime. Here’s how we calculate your estimate:
Roof Size
The first factor in your roof replacement’s cost is size. Roofing contractors normally start with a roof’s square footage, which accounts for 40-50% of the total estimate. A larger roof requires more materials, labor, and additional equipment, which all impact replacement pricing.
To calculate your roof’s square footage, multiply your house’s length times its width. Then multiply it by a number between 1.05–1.15 (if your roof is steep, choose the higher end of that range). This gives you a rough sense of its cost per square foot.
Beyond that, your estimate will take other factors into account, including:
The Materials You Select
When you hear the word “roof,” you might think of traditional asphalt shingles, which are popular. They’re also fairly straightforward to install, making them more affordable in many cases.
Asphalt shingles come in different styles—from the basic, 3-tab design to architectural shingles with added texture and color variety to give your home a visual boost. Some shingles offer unique protective features that resist hail, high winds, and algae growth. Pricing varies by brand, style, and product line.
Of course, asphalt isn’t the only material available. You might select traditional cedar shingles to match a historic home’s requirements, ceramic tiles to complement Mission-style architecture, or metal roofing to provide a sleek modern look that is exceptionally moisture-resistant.
Bottom line: Each material has its own unique cost per square foot. Compare them by price, durability, warranty, and more before making your final decision.
Steepness
This might surprise you, but your new roof’s overall price is influenced by how steep (or pitched) your house happens to be. It may seem like a small detail, but highly sloped surfaces mean your roofers will need to use extra safety equipment.
Steep roofs are more challenging to work on, and the crew will move slowly so they can do things properly and safely. The added cost reflects the added risk involved.
Any Underlying Issues
Once your old roofing materials are removed, a well-trained team (like ours) will do an inspection of the roof deck—the surface that your roofing system is attached to. This underlying structure can sometimes reveal moisture damage, rot, or signs of pest infestation.
If this happens, repairs will be required so your new roof adheres properly and gives you the high performance you deserve. Repair costs may be mentioned in your initial estimate if a leak or storm damage is evident upon inspection. Other repairs may not show up until old roofing is removed, meaning some costs may need adjustment as work gets done.
Crew Size and Experience
Clearly, the more workers needed to complete a job, the higher the overall investment. But there are other factors to think about (and appreciate!) when it comes to the roofing crew you hire.
If your house has many intricate elements, such as chimneys, skylights, dormers, and solar panels, you’ll want a roofer who knows exactly what to do to preserve those important features.
Teams like ours continually stay updated on our skills, and we like to retain people who are professional, experienced, and attentive to details. Sure, their expertise may cost a little more, but their excellent level of craftsmanship is well worth the peace of mind you’ll have in a job well done.
Complexity of Roofing Design
Have you ever noticed how some houses have a simple roof structure, while others have a lot of intricate dormers and other design elements? Well, the more complex the roof, the more labor and detailed work is required to update it.
All those nooks, crannies, and irregularly sized features need added care, labor, and materials, which are reflected in your roof replacement quote.
Time of Year
Did you know replacing a roof has an off-season and a peak season? Most homeowners have their roof updated during late spring, summer, and early fall, when the weather is easier to work around—but it means roofing contractors are busy, and that may affect the budget.
Colder weather may mean some delays (since we can’t work on an icy roof!), but since winter is a slower season, your estimate might be lower too.
A quick additional thought to consider: If a harsh storm has recently passed through St. Paul or Minneapolis, it might have left a lot of damage in its wake. In the storm’s aftermath, roofers will be busy, and that may affect pricing.
Additional Needs
If your house requires add-on tasks, it’ll affect the overall project cost. This can include to-dos like a gutter replacement, installing new roof vents, or repairs to your chimney. Usually, these needs are included in your estimate.
