A storm claim is paperwork plus persistence. We inspect, photograph and document the damage, meet the adjuster on the roof, and keep the scope tied to the actual work so the homeowner is not left covering the difference. Derek is the name that comes up in review after review for exactly that part of the job.
“Derek did an awesome job. What a battle it was with my insurance. They fought with the insurance and got me what I deserved…..a new roof. Crew did a great job with the work and clean up.”

Many homeowners start with a professional roof inspection to find out whether storm damage has actually occurred before filing a claim. It is free, and it means you file with evidence.
Policies vary, but storm damage claims are typically treated differently from other claims because they result from weather events affecting entire regions.
The timeline depends on the insurance company and the approval process. Once a claim is approved, most roof replacements are completed in one to two days.
Detailed roof inspection, photo documentation, meeting with the adjuster, and full roof replacement when approved. We make sure all storm-related damage is properly documented.
Honest and accurate roof assessments, quality materials built for Minnesota weather, and full support throughout the insurance claim process.
We believe homeowners deserve a straightforward, transparent process, especially when insurance is involved. Here is the sequence.

Brian, the owner, is on projects rather than behind a desk, and homeowners mention him keeping them updated and helping work through the insurance side of a claim. Derek Gajewski comes up most often in connection with insurance claims and with checking in while work is underway. Both names appear over and over in the reviews, which is the most honest introduction we can offer.
“Derek was amazing! He was both persistent and patient with our (awful) insurance company. He kept encouraging us and then was almost as happy as we were about the finished job.”Carey Erkal, homeowner review
“Derek did an awesome job. What a battle it was with my insurance. They fought with the insurance and got me what I deserved…..a new roof. Crew did a great job with the work and clean up. I need my garage sided in the near future and I will definitely be using BN again.”
“BN Builders recently replaced our roofing and siding as well as rewrapped our window frames. They were extremely efficient, showing up promptly and we are extremely satisfied with their workmanship and love the end results. The job supervisor as well as the owner, Brian, kept us updated throughout the process. Brian went above and beyond and was excellent with helping us continue to work through the Insurance for their portion of coverage due.”
“Derek was amazing! He was both persistent and patient with our (awful) insurance company. He kept encouraging us and then was almost as happy as we were about the finished job. We will recommend Derek and BN Exteriors as often as we can.”

Insurance policies vary, but storm damage claims are typically treated differently from other claims because they result from weather events affecting entire regions.
The timeline depends on the insurance company and approval process, but most roof replacements are completed quickly, usually one to two days, once a claim is approved.
That is why we meet the adjuster on the roof. We walk it together, point out every documented impact, and answer scope questions on the spot so the claim reflects the real scope of work.
Yes. Hail rarely stops at the roof. We document and repair storm damage to siding, gutters, downspouts, window frames and trim as part of the same job.
Coverage depends on the damage and your policy. We document the damage and guide you through the process so you can make an informed decision.
