Interlock® Aluminum Roofing — all-climates performance specs for Onamia Township, Minnesota
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
From the start to finish, we loved their work and communication. There were no nails, metal bits, or excessive noise. They listened to all questions and addressed our concerns. They were careful to make no promise of a start date that they could not fulfill. The rain this year made it hard to predict! I would do a commercial for them free to endorse their work and product!
Hi Peter, we wanted to convey to you how much we love our new Interlock roof! Several of our neighbors and friends have said they do, too! We love the look of it, and are so impressed with how beautifully finished it is integrated into the flashing materials. The Interlock scheduling staff was great to work with, and we are so happy with Jessie and his Interlock installation team. They are true craftsmen, and part artists! We loved how they treated our home with respect, and were always willing to address any questions we had. We watched as they worked on items until they had them just right; when we asked about some areas of concern multiple members of the installation team converged on the item and came down to explain and even illustrate with photographs how it was addressed. Again, we couldn't be happier and are enjoying our Interlock roof!
To: Peter Brylinke My Interlock Shake style system was installed in June of 2019. We have now had it for an entire year and experienced the roof through all season, climate and weather conditions. Not only do we value the new look of our roof but the performance of the new roof has been exceptional. In the winter we have seen the snow pile up on it only to slide off as soon as the sun warms it enough. We have noticed a difference in the summers also with a cooler house. The roof has met all of our expectations and we are extremely happy with our decision to install this roof. Last summer when the workers were working on the roof, we were so pleased with the time and effort the workmen put into making sure all aspects of our roof were taken care of. They were courteous, hard working, respectful and considerate of our needs as homeowners. Carlos was instrumental in making sure that we were happy with every aspect of the work that was being done. In closing, we are very impressed with our roof and have recommended this same system to many people we know and many people who just " data-wpil-keyword-link="linked">walk by and ask about it. We feel that we have made a great decision in putting this system on our home. ">" alt="Minneapolis MN 55409 Interlock Roof" width="2560" height="1920" />
Dear Peter, Thank you for your help with the installation and warranty transfer of our interlock roof. We have since sold our house and had good feedback about our roof from potential buyers. Neighbors loved our new roof and we had people drive by and actually snap pictures of it! You were right that the new roof would help sell our home! Thanks for all your help!
Dear Peter, I had Interlock Roofing install my black slate roof in the fall one year ago, and I couldn’t be happier! My roof still looks like new, and really stands out in my neighborhood. My old asphalt shingle roof was leaking. I had to shovel it every time it snowed because of " title="ice dams" data-wpil-keyword-link="linked">ice dams in my older 1950’s house. I have had no issues at all with my new Interlock roof. It was so nice only to have to shovel my driveway this winter and not worry about snow on the roof. It all just slid off in only a few days after each snowfall. Also, the team that you had out to install my roof was exceptional. I was very impressed with the quality of the team that installed my roof. They were all very polite and worked well together as a team. They worked very hard, and got the job done, and completed in less than three days. I’ve never had to have anyone come back to fix or touch anything up. Thank you for the great job the Interlock team did to replace my roof. I would recommend Interlock to anyone needing a new roof without hesitation!
Dear Peter, We remain delighted with our new Interlock roof. It’s now been through 2 Minnesota winters, a hailstorm, and several rain deluges and is still the top-notch performer that you said it would be. Thank you for your and Interlock’s integrity throughout the sale, installation, and service of our roofing project. We remain convinced that Interlock is indeed “the Midwest’s Best Roof”.
Dear Peter, I Wanted to let you know how pleased I am with my new Interlock roof. It looks terrific, and I am anticipating that I will never have to roof rake my roof again now that your product has been installed. My house is small, a 3-bedroom rambler, but the visual impact the Interlock roof has added makes it look like a castle! All of the contact I have had with your personnel, from yourself to the lead foreman on the job and the men doing the install was pleasant and professional. The cleanup after the job was done was great and it only took 1-1/2 days for a complete tear-off to complete the installation. Please use this letter as a personal recommendation for your company and your product.
Dear Peter, Installing the Interlock roof on our home has completely transformed and improved our home’s appearance. The installation of the roof along with the greatly improved flashings have made a great difference. Because of that, our stucco was able to match our home so we look like new. An improvement I didn’t expect was the change in temperature of our second floor. Usually unbearable " data-wpil-keyword-link="linked">hot on a 90-degree day. It’s now 10-15 degree cooler and livable. We also received a sizeable discount on our homeowners’ insurance because of the roof’s resistance to fire. We’re sure that having to “Never roof again” will help us sell our house should that be necessary. Thank you from two satisfied customers.
My Interlock ">Shake Style Roof in Aged Copper color was installed between December 21st and December 31st. Snow has covered most of the house and garage since it was installed, so I haven’t been able to enjoy the new look yet, but during the installation and before the snow it was obvious it I going to look great. I am glad I had them put Interlock ">Shakes on my 8ft x 16ft hip-roofed storage shed as well. There are a lot of huge oak trees close to my house and they had caused the heavy cedar hand-split shakes to deteriorate from moss growing on them. I knew I needed a roof that would not have this problem in the future. I am a retired mechanical engineer and had built the house and garage myself. I studied the specs on steel, stone coated steel and several aluminum style shakes, before finally settling on the Interlock product. I believe it will prove to be a good choice. I was very impressed with the quality and design of all the types of flashings, ridge vent, and fasteners that were expertly installed. I truly expect this roof to last and look great for generations. I was also very impressed with the crew who did the work under Juan and Carlos’ direction. They worked tirelessly in some difficult weather conditions and short daylight hours. A number of minor changes were made on the fly with gutters, snow guards and roof penetrations and they were all executed precisely. They were very careful in making sure the roofs were protected overnight, on weekends and during the Christmas holiday. They did a great job of cleaning up the difficult mess made removing the decayed shakes. I guess I won’t know for sure if there are any problems until we get some heavy rains in the spring and summer, but as of now, I would be happy to show the roof and talk to any prospective clients that are considering the Interlock product.
I love my new roof. It looks great and I know the house is in better shape without the heavy deteriorating asphalt shingles. My house is the only one on the block with no snow on the roof, and I can't wait to hear it in the rain
We are delighted with the workmanship and quality of our new roof. It has exceeded our expectations, and we highly recommend an Interlock Roof to anyone looking to replace an old roof.
Dear Interlock Roofing, We are writing to share with you our experience with you, your employees, and the new roof. We built a brand new home and moved in January 1997. Within a few years, we were experiencing shingles that were curling and being removed by the wind. By the summer of 2007, it was imperative that we re-roof our home. Fortunately, we saw an ad in the local paper for your product. Below are just a few of the benefits we appreciate with the aluminum interlocking roofing shingles: The service and attention to our roofing project by Scott Bohnen from signing the contract to follow-up after the installation. The fact that the workforce followed safety procedures by wearing safety gear (we have a steep roof). Daily attention to our project until it was completed, about one week in total. Aesthetically pleasing roof, with numerous comments by friends and neighbors and those just passing by. EXCELLENT CURB APPEAL! The roof is quieter during rain storms than with regular asphalt shingles. We often have to verify that it is raining by visually looking or going outside. The roof reflects light so that we have experienced reduced air conditioning costs in the summer. In the winter, the heating bill is reduced as well and that may be in part to the aluminum shingle along with the polypropylene lining between the old and new shingles. No matter the reason, our heating and cooling bills are reduced. The fact that the roof is aluminum and it can be recycled at the end of its life expectancy. The 50-year, one time transferable, warranty. We could go on and on but we are very pleased with our roof and thankful that we will never have to re-roof again. Thank you.

Metal Roofing FAQs for Homeowners in Onamia Township
The following metal roofing FAQs are designed specifically for homeowners in Onamia Township, Minnesota. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Onamia Township.
How does a metal roof handle Minnesota's heavy snow and ice dams?
Aluminum's smooth, slippery surface naturally sheds snow and ice better than asphalt shingles, reducing ice dam buildup during Onamia's typical 107 cm annual snowfall. The four-way interlocking panels lock together so tightly that wind-driven snow cannot find gaps to enter, and the ultralight weight—about 0.41 lb/sq ft for the Shingle profile—means snow load never stresses your home's frame the way heavy slate or clay tile does. Optional snow guards can be installed if you want to slow shedding for safety. With 74 freeze-thaw days per year here, the aluminum's self-healing oxide layer flexes through temperature swings without cracking or splitting, unlike wood shakes or concrete tiles.
Will freeze-thaw cycles in Minnesota damage my metal roof over time?
No—aluminum is actually more durable than materials that absorb water during freeze-thaw stress. Onamia experiences about 74 freeze-thaw days annually, which can crack wood, tile, and asphalt, but aluminum's non-porous surface doesn't absorb moisture that expands when it freezes. The roofing-grade 3105-H24 aluminum alloy simply expands and contracts uniformly with temperature swings; the Alunar 70% PVDF fluorocarbon coating—warranted 30 years against chalking—stays intact through those cycles. Your roof's weakest point is actually the fastener system and seals, which we install to breathe with seasonal movement. Steel roofing rusts at fasteners in this climate; aluminum fasteners won't.
Can aluminum metal roofing rust like steel roofs do?
Aluminum cannot rust because it contains no iron—the element that oxidizes and creates rust. When aluminum's surface scratches, it forms a new oxide layer automatically, creating a self-healing barrier that protects the metal underneath. This matters in Onamia because our 650 mm of annual rainfall and 108 km/h wind gusts mean moisture constantly contacts your roof, and salt spray from road treatments in winter accelerates corrosion of steel. Our panels use roofing-grade 3105-H24 aluminum alloy per ASTM B209 and apply the Alunar 70% PVDF fluorocarbon finish to both sides of each panel—extra insurance against salt air. Steel roofing rusts at fasteners and seams within 15–20 years in this climate; aluminum won't corrode at all.
Do I need to reinforce my roof framing for a metal roof?
Almost certainly not. Interlock's Slate profile installs at just 0.41 lb/sq ft, and even the heavier Tile profile weighs only 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. For perspective, a typical asphalt shingle roof weighs 2–4 lb/sq ft, so metal roofing is actually lighter than what you may already have. Because the weight is so low, you can install metal panels directly over most existing roofs without tearing off and rebuilding, saving money and eliminating the asphalt-to-landfill waste that hits Mille Lacs County landfills every year. The four-way interlocking design transfers wind loads evenly across your structure rather than concentrating stress at nails. Your home's frame was engineered for the roof it currently has; metal roofing typically needs no structural changes.
Will a metal roof blow off in Minnesota windstorms?
No—the four-way interlocking panels are engineered to resist wind speeds up to 120 mph when installed to spec, and Onamia's typical gusts of 108 km/h (67 mph) are well below that threshold. The interlocking design means each panel locks to its neighbors on all four edges, so wind cannot get underneath and lift the roof the way it can separate loose shingles. Our ICC-ES ESR-1790 evaluation confirms this system meets IBC and IRC codes for your region. The warranty backs up the installation: if your roof fails due to wind under 120 mph, we cover it. Straight-line derechos and microbursts do happen in Minnesota, but they're rare; your much more common 20–30 km/h daily winds won't move a properly installed metal roof at all.
Does metal roofing hold up to Minnesota hail, and can I get insurance discounts?
Yes—Interlock metal roofing carries a UL 2218 Class 4 impact rating, the highest available, and the warranty specifically covers perforation from hailstones up to 1.5 inches. Class 4 means the panel resists impact from 2-inch steel balls dropped from 20 feet, a test far more severe than typical Midwest hail. Many homeowners and insurers don't realize metal roofing often qualifies for premium discounts because it's so impact-resistant; call your agent with the UL 2218 Class 4 rating and ask about a reduction. Mille Lacs County experiences hail occasionally, and when it does, aluminum panels simply dent—they don't shatter, split, or lose integrity like asphalt, wood, or tile. Even a visible dent doesn't compromise the roof's waterproofing or wind resistance.
Is metal roofing worth the upfront cost compared to asphalt shingles?
Over the roof's lifetime, metal roofing is substantially cheaper. Asphalt shingles typically last 15–25 years before you replace them; metal roofing lasts 40+ years with proper installation, meaning you buy asphalt three or four times while metal pays for itself once. Our Guardian Warranty is lifetime limited and non-prorated for the original owner, covering rusting, rotting, splitting, cracking, curling, and impact damage—the exact failures that send Onamia homeowners up to the hardware store. Factor in zero-maintenance costs (no power washing, re-sealing, or shingle replacement), no tear-off and disposal fees (asphalt adds up), potential insurance discounts for Class 4 hail resistance, and energy savings from energy-efficiency colors with up to 0.55 solar reflectance, and the math shifts fast. The upfront premium vanishes when you plan to stay 20+ years.
What does the installation process look like, and can you install over my existing roof?
Yes, Interlock installs over most existing roofs without tearing off, which saves thousands in labor and disposal costs. Our installer measures your roof, orders panels in the profile and color you choose (Slate, Cedar Shingle, Shake, Standing Seam, or Mediterranean Tile), and typically completes installation in 1–3 days depending on complexity. We secure panels with stainless steel fasteners into your existing sheathing or over asphalt shingles, and the four-way interlock creates a unified system that moves as one. Tearoff is only needed if your framing is damaged or if local code requires it (rare). Since our aluminum panels weigh roughly 0.41–0.59 lb/sq ft versus asphalt's 2–4 lb/sq ft, your existing structure handles the load easily. Interlock Metal Roofing has served this region since 2001 and coordinates every detail so you're not disrupted.
Is metal roofing better for the environment than asphalt shingles?
Significantly. Aluminum roofing is about 95% recyclable at end of life, and recycled aluminum takes just 5% of the energy to produce compared to virgin aluminum. Because it lasts 40+ years instead of 15–25, you eliminate multiple tear-off cycles that send asphalt shingles to landfills. Onamia and Mille Lacs County see thousands of tons of asphalt roofing disposed annually; metal roofing breaks that cycle for one home at a time. The energy-efficient energy-efficiency colors—with thermal emissivity 0.84—reflect heat that asphalt absorbs, reducing cooling loads and your carbon footprint over decades. Even manufacturing our roofing-grade aluminum in Delta, BC, and shipping it here uses less total energy than replacing asphalt every 20 years. If environmental impact matters to you, metal roofing is the choice that pays dividends for 40 years straight.
Is metal roofing fire-safe, and does it meet Minnesota building codes?
Yes—aluminum is non-combustible, and Interlock offers Class A fire-rated panels, the highest fire classification available. Our system meets ICC-ES evaluation report ESR-1790, which covers the 2024 and 2025 editions of the International Building Code (IBC) and International Residential Code (IRC), so you're compliant with Minnesota state and Mille Lacs County code. Non-combustible roofing matters if you live in a wildland-urban interface area or if your insurance or mortgage lender requires Class A ratings. Asphalt shingles are Class C or lower and will ignite; wood shakes are highly flammable. Metal roofing with Class A fire resistance gives you peace of mind and may lower insurance premiums in fire-prone regions. Our aluminum core will not burn; the Alunar 70% PVDF coating is also Class A rated.
