Interlock® Aluminum Roofing — all-climates performance specs for Excelsior, 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 Excelsior
The following metal roofing FAQs are designed specifically for homeowners in Excelsior, 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 Excelsior.
How does a metal roof handle Minnesota snow and ice buildup?
Interlock's four-way interlocking aluminum panels shed snow and ice faster than asphalt because the smooth surface has less friction—critical in Excelsior, where you average about 95 cm of snow annually and experience roughly 79 freeze-thaw cycles each year. The lightweight design (Slate installs at 0.41 lb/sq ft) means no structural reinforcement, and snow guards can be added where desired. Unlike asphalt, aluminum won't degrade from repeated freezing and thawing; the oxide layer that prevents rust also resists the expansion and contraction that cracks traditional materials.
Why is aluminum better than steel roofing in a place with wet winters?
Aluminum fundamentally cannot rust because it contains no iron—the element that oxidizes and corrodes in moisture. Instead, aluminum develops a self-healing oxide layer that thickens over time and seals any scratches automatically. With Excelsior averaging about 800 mm of annual rainfall plus 95 cm of snow melt, continuous wetness is the norm, and this chemistry gives aluminum roofing an inherent advantage steel simply doesn't have. Your Interlock roof will never experience the rust staining, structural weakening, or shortened lifespan that steel roofs face in climates like yours.
Will freeze-thaw cycles in Minnesota damage an aluminum metal roof?
No. Aluminum's crystalline structure and flexibility actually perform better through freeze-thaw stress than brittle materials like asphalt, wood, or ceramic tile. Excelsior experiences about 79 freeze-thaw days per year, which would cause asphalt shingles to curl, crack, and split—but aluminum simply cycles without degradation. The 3105-H24 / 3003-H24 alloy used in Interlock panels is engineered for this exact behavior. Combined with the Alunar 70% PVDF coating (warranted 30 years against chalking and fading), your roof emerges from Minnesota's wet-freeze climate intact year after year.
Can an Interlock metal roof withstand Minnesota's wind gusts?
Yes. Interlock's four-way interlocking system is warranted to resist winds up to 120 mph, and Excelsior's typical gusts average around 94 km/h (58 mph)—well within that rating. The interlocking design means each panel is mechanically locked on all four sides to its neighbors, distributing wind load across the entire roof rather than relying on fasteners alone. This engineering gives you protection that far exceeds the seasonal wind stress your region experiences, even during spring storms. UL 2218 Class 4 impact testing (the same standard) confirms the panels' structural integrity.
Do I need to reinforce my roof structure for a metal roof?
Not for Interlock. The Mediterranean Tile profile, though it replicates heavy clay or concrete tile, installs at just 0.59 lb/sq ft—about 96% lighter than the real thing. This exceptional lightness means most existing homes need no structural reinforcement, and you can often install directly over your current roof, saving thousands in labor and disposal costs. Even traditional asphalt can be heavier. Interlock's aluminum construction delivers the profile you want without the engineering upgrades that slate or tile would demand, making it practical for nearly any Excelsior home.
Does Interlock roofing hold up to Minnesota hail, and will my insurance notice?
Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This certification tells insurers your roof is exceptionally impact-resistant, which can qualify you for wind and hail premium discounts on homeowners' policies. Check with your carrier about incentives for Class 4 roofing. Excelsior's climate history and the documented durability of a roof that's been installed from coastal homes to Antarctica mean you're protecting your structure and potentially lowering your annual insurance cost.
What maintenance does an Interlock metal roof need in Minnesota winters?
Very little. Unlike asphalt shingles, which degrade under UV and need algae treatment and regular inspection, Interlock panels require only occasional gutter clearing—the same as any roof. The Alunar 70% PVDF fluorocarbon coating (applied to both sides) resists the salt air, freeze cycles, and moisture stress that degrade wood shakes and ceramic tile. You won't deal with curling, cracking, splitting, or moss growth. With about 3,128 sunshine hours per year in Excelsior, UV degradation is a real concern for asphalt; aluminum's finish laughs at it. Annual inspection is smart practice, but costly repairs and replacements are eliminated.
Is Interlock roofing actually better for the environment than asphalt?
Yes, significantly. Interlock aluminum is approximately 95% recyclable at end-of-life, versus asphalt shingles that end up in landfills for decades. You avoid the tear-off-to-landfill cycle entirely: when an Interlock roof eventually retires (far in the future), the aluminum enters the recycling stream with high value, never the waste stream. Over its 50+ year lifespan, one roof avoids 2–3 asphalt replacements and their disposal impact. Interlock is CALGreen-verified for reduced maintenance, which also means fewer service trips and less environmental footprint. If you care about closing the material loop, aluminum roofing is the choice that matters.
Will an Interlock metal roof improve my home's resale value in Excelsior?
Absolutely. A roof that won't need replacement for 50+ years, carries a transferable lifetime warranty, and visually replicates slate, cedar, or tile is a significant selling point. Buyers in Minnesota appreciate durability against freeze-thaw and snow load stress; they understand that asphalt will need replacement within years. The five profile options—Slate, Cedar Shingle, Shake, Standing Seam, Mediterranean Tile—let you choose the aesthetic that suits your home's character and neighborhood. Real estate professionals recognize Interlock as a premium, permanent upgrade that signals structural integrity and low future maintenance risk, making your home more attractive at appraisal and negotiation.
How long does it take to install an Interlock metal roof, and can it go over my existing shingles?
Installation timeline depends on roof size and complexity, but Interlock's lightweight design and interlocking system make installation faster than slate, tile, or standing seam alternatives. One of Interlock's key advantages is that you can often install directly over an existing asphalt roof, eliminating tear-off labor and debris removal costs—a significant savings for Excelsior homeowners. Your installer (Interlock Metal Roofing, serving the region since 2001) will assess your current roof's condition and structure; if it's sound and properly fastened, the new Interlock panels lock over it without reinforcement needed. Details and timeline are best discussed during an on-site estimate.
