If you’re searching for a roofing contractor in St. Peter, MN after the April 13, 2026 hailstorm, you’re probably fielding calls and door-knocks from every direction. St. Peter itself is a smaller market, so several of the area’s most established roofers are based in nearby Mankato or North Mankato rather than St. Peter proper.
We put together this guide to help St. Peter homeowners compare their options without the guesswork. Below are some of the region’s roofing companies worth considering, including a Minnesota-based contractor with statewide storm-claims experience, followed by what to look for and answers to the questions we hear most after a storm like this one.
What the April 13, 2026 Hailstorm Means for Your Roof
The storm that moved through Nicollet County on April 13, 2026 produced hail large enough to damage roofs, siding, gutters, and windows across the St. Peter area. Hail that size can bruise or crack asphalt shingles and dent soft metal — gutters, downspouts, and AC units — without always being obvious from the ground. That makes a professional inspection important even if your roof looks fine from the driveway: granule loss and cracked seals are often only visible up close, and insurance policies typically have a filing window that starts the clock on getting damage documented.
1. Innovative Building & Design (IBD)
Innovative Building & Design has been serving Minnesota homeowners since 2008 and is based in Blaine, MN, with a second office in Eau Claire, WI. IBD is licensed in Minnesota and specializes in roofing, storm restoration, siding, windows, gutters, and remodeling.
What sets IBD apart is its dedicated Claims Success Manager and extensive experience with complicated storm claims. This is especially valuable in St. Peter, where many homeowners have been told their roofs don’t have enough damage from the April 13 hailstorm to qualify for coverage. Even if your claim was already denied, IBD can perform a second inspection, document overlooked damage, and help determine whether a reinspection is warranted.
IBD is also GAF Certified Plus and employs its own carpenters for remodeling and specialty repairs—giving homeowners a full-service contractor rather than a roofing-only storm company.

2. Millersberg Construction
Millersberg Construction, based in Northfield, serves southern Minnesota including St. Peter and Nicollet County with roofing, siding, and gutter work. The company handles both residential and commercial roof replacement, giving St. Peter homeowners a regional option beyond the Mankato-based contractors.
3. Bauer Roofing & Construction
Bauer Roofing & Construction is a small, family-owned company based in Eagle Lake, just outside Mankato. The company focuses on roof repairs, replacements, and maintenance for homeowners throughout the Mankato and St. Peter area, with a straightforward, no-frills approach.
4. D&Z Construction (DZ Roofing)
D&Z Construction, based in Mankato, offers roofing and siding installation for homeowners throughout the Mankato–St. Peter corridor, handling both insurance-claim roof replacements and out-of-pocket repair work.
5. Boelter Window, Siding & Roofing
Boelter Window, Siding & Roofing is a small, family-run operation based in North Mankato. True to its name, the company handles windows and siding alongside roofing — useful if the April storm damaged more than just your roof.
6. Midwestern Construction
Midwestern Construction, based in Mankato, works across Minnesota, South Dakota, and Iowa, offering roofing, siding, and pole shed construction. For St. Peter homeowners with outbuildings or detached structures damaged in the storm, that broader scope of work is worth knowing about.
Why St. Peter Homeowners Still Choose IBD
We won’t pretend IBD has the same deep local roots in St. Peter that several Mankato-based contractors have — we’re a statewide contractor working out of Blaine and Eau Claire. What St. Peter homeowners tell us matters most after a widespread hail event like April 13th is the claims support: adjusters get backed up fast after a storm like that, and initial inspections sometimes miss damage that a more thorough second look catches. Our Claims Success Manager specializes in exactly that — documenting what the first inspection missed and pushing for a fair reassessment when a claim comes back denied or underpaid.
How to Choose a Roofing Contractor in St. Peter
A few things worth checking before you sign with any roofing contractor, regardless of who you choose:
- Response time after a storm. St. Peter is small enough that some reputable contractors are based in Mankato or beyond — ask how quickly they can realistically get a crew out for an inspection or repair.
- Manufacturer certifications. Certifications like GAF Certified Plus or similar programs typically mean stronger manufacturer-backed warranties on materials and workmanship.
- In-house crews vs. subcontractors. Ask whether the crew doing the work is employed directly by the company or subcontracted out for each job.
- Insurance claims experience. After a widespread hail event like April 13, adjusters get backed up fast. A contractor experienced in documenting damage and working directly with insurers can make the claims process significantly less stressful. Our step-by-step guide to storm damage insurance claims walks through what that process typically looks like.

Two owners who are still involved in the work every day is a big part of why homeowners can reach a real decision-maker when they call.
Frequently Asked Questions About Roofing in St. Peter, MN
Does my homeowners insurance cover the April 13, 2026 hail damage?
In most cases, yes. Standard Minnesota homeowners insurance policies cover hail damage to your roof, siding, gutters, and windows. The key is getting the damage documented quickly and filing before your claim window closes.
How do I know if I really have hail damage?
You may not be able to tell from the ground. Hail damage to shingles often looks like dark spots or bruising that’s only visible up close. A free inspection is the most reliable way to get an honest answer.
Will I have to pay out of pocket?
If the damage is covered by your insurance claim, your primary cost is typically your deductible. A contractor experienced with claims will work directly with your adjuster to help maximize what’s covered.
How much does a new roof cost in St. Peter, MN?
Most asphalt shingle roof replacements run a few thousand dollars into the low five figures depending on roof size and material. If the damage is storm-related, insurance may cover most or all of it beyond your deductible.
What if my insurance claim was already denied?
It’s worth a second opinion. Initial adjuster inspections sometimes miss damage, especially after a widespread event like April 13th when adjusters are moving quickly through a high volume of claims. A second, more thorough inspection can change the outcome.
How soon should I schedule an inspection?
As soon as it’s safe to do so. Insurance policies often have filing windows, and damage left unaddressed — even damage that looks minor — can worsen with the next rain or freeze-thaw cycle.
