Interlock® Aluminum Roofing — all-climates performance specs for Heidelberg, 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 Heidelberg
The following metal roofing FAQs are designed specifically for homeowners in Heidelberg, 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 Heidelberg.
How does a metal roof handle Minnesota's snow and ice with 95 cm falling most winters?
Interlock's four-way interlocking panels shed snow efficiently and resist ice dam formation because aluminum doesn't absorb moisture or expand when frozen. With about 95 cm of snow per year and roughly 77 freeze-thaw cycles annually in Le Sueur County, your roof needs a material that won't crack, curl, or split—asphalt and wood do exactly that. Interlock aluminum profiles lock together to channel meltwater safely off the roof, and because the panels are non-porous, freeze-thaw cycling won't degrade them. Optional snow guards keep snow in place if aesthetics demand it.
Can a metal roof rust in Minnesota winters, and why should I choose aluminum over steel?
No—aluminum literally cannot rust because it contains no iron. Instead, it forms a self-healing oxide layer that seals instantly when scratched, protecting the metal underneath indefinitely. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) coated on both sides with Alunar 70% PVDF, warranted 30 years against chalking and fading. This dual-sided protection matters in cold climates where snow melt and freeze cycles accelerate corrosion in steel. Your roof will outlast the house without the rust maintenance that steel demands.
Will a metal roof crack or warp after 77 freeze-thaw cycles every year?
No—freeze-thaw cycling is actually where aluminum roofing excels. Asphalt and wood expand and contract with temperature swings, eventually cracking and losing flexibility. Aluminum expands and contracts uniformly without retaining moisture, so the roughly 77 freeze-thaw days Le Sueur County experiences annually won't degrade the material. Interlock panels lock four-ways to accommodate this movement without separating or leaking. The Guardian warranty covers cracking and curling for the original owner's lifetime, and transfers 50 years to the next owner—confidence backed by nearly three decades of field performance since 1998.
How secure is a metal roof in Minnesota wind gusts up to 99 km/h?
Very—Interlock panels are warranted to resist sustained winds up to 120 mph (193 km/h), which exceeds the peak gusts Heidelberg typically experiences. The four-way interlocking design prevents panels from lifting, separating, or rotating, even in the strongest regional wind events. With daily-average winds around 21 km/h and occasional gusts approaching 99 km/h, your roof stays locked down across all seasons. This mechanical interlock is far superior to fastener-dependent systems; the panels themselves are the structural security.
Do I need to reinforce my home's structure for a metal roof, or can it install over what I have?
No reinforcement needed—that's the defining advantage of Interlock's weight. The Slate profile installs at roughly 0.41 lb per square foot, the Shake at 0.58 lb/sq ft, and the Tile at about 0.59 lb/sq ft, making the Tile profile approximately 96% lighter than concrete or clay tile. This extraordinary lightness means Interlock installs directly over most existing roofs without structural modifications, saving thousands in labor and engineering. In Minnesota, where snow adds roughly 95 cm of weight annually, a metal roof actually reduces total load on your framing compared to heavier roofing materials.
Is metal roofing worth the upfront cost, or should I just re-roof with asphalt again?
Metal roofing is the last roof you'll likely install, which changes the math. Asphalt needs replacement every 15-20 years; Interlock's lifetime limited, non-prorated warranty for the original owner and 50-year transferability to the next owner eliminate that cycle. Over a 50-year horizon, you avoid multiple asphalt tear-offs, disposal fees, and re-roofing labor. Energy efficiency also cuts heating and cooling costs—energy-efficient colors achieve up to 0.55 solar reflectance, meaningful during Heidelberg's 3,163 annual sunshine hours. The upfront investment recouped through longevity, energy savings, and avoided replacement cycles makes it the economical choice over time.
How much maintenance does a metal roof require compared to asphalt or tile?
Virtually none. Asphalt requires granule replacement, moss treatment, and annual inspection; wood shake demands preservative recoating every 5-10 years; tile needs mortar repointing and regular clearing. Interlock aluminum requires only occasional gutter cleaning and perhaps annual inspection—no coating renewal, no sealing, no treatment. The Alunar finish is self-protecting and warranted 30 years against fading and chalking. In a climate with 861 mm of rain and about 95 cm of snow annually, the self-draining, non-absorbing nature of aluminum means no moisture damage, no rot risk, and no structural decay. You've essentially eliminated roof maintenance from your home-care list.
Will hail damage a metal roof, and can I get insurance discounts?
Interlock achieves UL 2218 Class 4 impact rating—the highest classification available—and the Guardian warranty covers perforation from hailstones up to 1.5 inches. This proven durability often qualifies you for insurance premium reductions; contact your agent with the ICC-ES ESR-1790 and Intertek listing 33876 specifications. Class 4 means aluminum panels resist impact damage far better than asphalt, wood, or concrete tile. Although Heidelberg's climate data doesn't indicate severe hail frequency, the protection is there if storms strike—and the warranty backs every panel against impact failure.
Is metal roofing actually better for the environment than replacing my asphalt roof again?
Yes—Interlock aluminum is approximately 95% recyclable, ending the asphalt tear-off-to-landfill cycle permanently. Every time you replace asphalt, tons of shingles enter landfills; Interlock roofing ends that waste stream. At end-of-life, the aluminum is worth recycling and returns to the supply chain. CALGreen verification confirms reduced maintenance requirements, which also means fewer truck trips for repairs and treatments over decades. In a state conscious of environmental footprint, choosing a roof that doesn't degrade into landfill waste and won't require replacement for 50+ years aligns economic sense with ecological responsibility.
Can a metal roof catch fire or spread flames like asphalt or wood shake?
Non-combustible aluminum eliminates the fire hazard that asphalt and wood roofing carry. Interlock achieves Class A fire classification—the highest rating—because aluminum doesn't ignite or propagate flames. This matters for insurance ratings, wildfire-adjacent properties, and simple peace of mind. The ICC-ES ESR-1790 evaluation confirms code compliance for fire performance under IBC/IRC standards. If you've ever worried about a spark igniting your roof, aluminum roofing removes that risk entirely. Many insurers recognize non-combustible roofing with discounts; check with your agent about savings on a Class A-rated metal roof.
