Class 4 impact-resistant shingles carry a UL 2218 rating — the highest impact classification available for residential roofing. To earn this rating, the shingle must withstand a 2-inch steel ball dropped from 20 feet without cracking. In Maple Grove's hail corridor, that means significantly better performance after the spring and summer storm events that cause most of the local roofing damage each year.
Several Hennepin County homeowner insurance carriers offer premium discounts of 15 to 30 percent for homes with Class 4 rated roofing systems. The discount requires specific documentation from your installer — the UL 2218 rating certificate and the manufacturer's product data sheet. We provide both after installation and can walk you through the process of submitting to your underwriter.

The UL 2218 test simulates real hail impact conditions. Class 4 is the highest achievable rating and is what Hennepin County carriers recognize for premium discount eligibility. We install only products that carry this certification.
We provide the manufacturer's product sheet and UL rating certificate after installation. Most carriers require you to submit these to the underwriting department — we give you exactly what you need and can guide you through the submission process.
Class 4 shingles outperform standard architectural shingles under repeated hail exposure and thermal cycling. For Maple Grove homeowners replacing a roof in the 1990s housing stock, upgrading to Class 4 is often the most cost-effective long-term decision when factoring in insurance savings and reduced future repair frequency.

We serve homeowners across the Maple Grove west metro corridor — including Rogers, Dayton, and Champlin. Whether you are dealing with storm damage on a Rogers acreage property, a Dayton home with an aging 1990s shingle roof, or an HOA-governed replacement in Champlin, we bring the same permitted process and honest assessment to every job in the service area.
From full residential roof replacement to storm damage repair, hail assessments, ice dam prevention, and emergency response — we handle the complete scope of residential roofing for Maple Grove homeowners and surrounding west metro communities.
Frequently Asked Questions
Residential Roofing can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
Most Maple Grove homes built between 1990 and 2005 are now 20 to 30 years old — right at the point where asphalt shingles start failing. We inspect the decking, flashing, and granule loss to give you an honest replacement vs. repair call before small problems become expensive ones.
Minnesota freeze-thaw cycles and hail seasons are hard on roofing systems. We recommend a spring inspection after ice dam season and a fall inspection before snow loads return. Catching cracked flashing or lifted shingles early in Maple Grove typically costs a fraction of emergency repairs after a winter storm.
Maple Grove residential roof replacements require a permit through the city. We pull all Hennepin County permits, schedule the required inspections, and handle the paperwork — you don't have to coordinate anything with the building department.
Class 4 impact-resistant shingles are rated to withstand 2-inch hail strikes without cracking. Several Hennepin County insurance carriers offer a documented premium discount — typically 15 to 30 percent — for homes with Class 4 shingles. We provide the certification documentation your carrier requires.
Most complete residential replacements in Maple Grove take one to two days depending on roof size, pitch, and whether decking repairs are needed. We stage materials the evening before so work starts early and your home is fully weatherproofed before we leave.
We work with all major carriers. We document the damage thoroughly — photos, measurements, material samples — so your adjuster has everything needed to process the claim. We also do supplemental requests if the initial estimate misses items, which is common after significant hail events.
For most Maple Grove homeowners, yes. The insurance premium savings alone frequently offset the modest price difference within three to five years, and the product lasts significantly longer under Minnesota hail exposure than standard architectural shingles.
Several Hennepin County carriers including major regional underwriters have documented discount programs for Class 4 impact-rated materials. We provide the UL 2218 impact rating certification and the manufacturer's product sheet, which is typically what the carrier requires to apply the discount.
We provide the UL 2218 Class 4 rating certificate and the manufacturer's product data sheet after installation. Most carriers require you to submit these to the underwriting department — we can walk you through that process to make sure the discount is applied correctly.
Class 4 shingles require the same installation process as standard architectural shingles and should always be installed by a contractor who understands the manufacturer's warranty requirements. We install to full manufacturer spec on every project, which is required for the warranty to be valid.

We had a 28-year-old roof on a 1995 build in the Elm Creek area. They came out, gave us a straight assessment, and had it replaced in one day. The permit inspection passed first visit. No drama.

We went with Class 4 shingles based on their recommendation. My insurance agent confirmed the discount was applied. That's the kind of advice that actually saves you money — not just an upsell.
Sandra Kowalski

Called them after the June hail event. They were on-site the next morning, documented everything we needed for the claim, and handled the supplement when the adjuster initially underestimated the damage. Got a full replacement approved.
