Interlock® Aluminum Roofing — all-climates performance specs for Greenfield, 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 Greenfield
The following metal roofing FAQs are designed specifically for homeowners in Greenfield, 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 Greenfield.
How does a metal roof handle heavy snow in Minnesota winters?
Interlock's four-way interlocking panels shed snow safely and resist the ice-dam damage that degrades asphalt shingles through freeze-thaw cycling. Greenfield receives about 95 cm of snow annually across roughly 79 freeze-thaw days, where repeated melting and refreezing crack and curl traditional materials. Aluminum's non-porous surface prevents water absorption, so ice doesn't degrade the panel itself. Metal roofs installed over solid decking with proper underlayment remain quiet during snowmelt and allow snow to slide naturally when conditions permit, reducing dangerous buildup on gutters.
Why does freeze-thaw damage asphalt but not aluminum roofing?
Asphalt absorbs water into its granules and matrix; when Minnesota's 79 annual freeze-thaw days arrive, that trapped water expands as it freezes, cracking and curling the shingles from inside. Aluminum's solid, non-porous 3105-H24 and 3003-H24 alloy absorbs zero moisture, so freeze-thaw cycling cannot degrade it internally. Its oxide layer self-heals when scratched, and the Alunar 70% PVDF coating (warranted 30 years) protects the surface. Over Greenfield's ~796 mm of rain annually, this distinction directly extends roof life.
Can an aluminum roof rust in Minnesota's wet climate?
Aluminum cannot rust because it contains no iron—rust is iron oxide, and aluminum instead forms a thin, self-healing oxide layer that actually protects the metal underneath. Even in salt-air coastal environments, Interlock panels (coated both sides with Alunar 70% PVDF fluorocarbon finish) remain stable; the company has installed roofs from coastal homes to an Antarctic research station since 1998. For Greenfield's inland location with ~796 mm annual rainfall and typical wind gusts to 94 km/h, this corrosion immunity means no rust staining, no structural weakening, and no replacement cycles forced by oxidation.
Do metal roofs blow off in Minnesota windstorms?
No. Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—far exceeding Greenfield's typical wind-gust peaks of 94 km/h. The mechanical interlock between adjacent panels (not fasteners alone) distributes wind load across the entire roof assembly, so each panel reinforces its neighbors. ICC-ES evaluation report ESR-1790 confirms compliance with IBC/IRC wind standards. This design means spring squalls, summer thunderstorms, and winter gales do not lift, separate, or damage the roof.
Will my house need structural reinforcement for a metal roof?
No structural reinforcement is required. Interlock's Mediterranean Tile profile, for example, weighs only ~0.59 lb/sq ft—about 96% lighter than concrete or clay tile—and can install directly over most existing asphalt roofs without any frame upgrades. The Shingle profile weighs ~0.41 lb/sq ft and Shake ~0.58 lb/sq ft. This extraordinary lightness means Greenfield homeowners avoid the cost and disruption of reinforcing roof trusses or walls. It also simplifies roof replacement logistics and reduces long-term structural fatigue from the dead load that asphalt shingles accumulate over decades.
Does a metal roof help with hail damage and insurance claims?
Yes. Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the Guardian warranty even covers perforation from hailstones up to 1.5 inches. Many Minnesota insurers recognize this resilience and offer premium discounts for Class 4-rated metal roofs, since claims for impact damage are rare. Greenfield's climate includes occasional severe weather, and metal's proven hail resistance contrasts sharply with asphalt shingles, which dent, fracture, and lose granules under impact. Request your insurer's discount schedule when you install; the premium savings often accelerate payback.
Is metal roofing worth the upfront cost compared to asphalt shingles?
Metal roofing costs more initially but eliminates the asphalt replacement cycle, making it the last roof you buy. Asphalt shingles last 15–20 years in Minnesota's ~79 freeze-thaw days per year; you'll replace them 2–3 times over 50 years. Interlock's lifetime limited warranty covers the original owner for rusting, rotting, splitting, cracking, and curling—with no prorated deductible. Total cost of ownership (material + labor + waste disposal) over 50 years favors metal decisively. Add the one-time-transferable 50-year warranty term for the next owner, and metal roofing becomes the economically rational choice, not a premium upgrade.
How much maintenance does a metal roof require?
Virtually none. Unlike asphalt (requires spot repairs and granule replacement), wood shake (splits and rots in freeze-thaw cycles), or clay tile (cracks and needs repointing), Interlock aluminum panels are CALGreen-verified for reduced maintenance. Greenfield's ~796 mm annual rainfall and ~19 km/h mean winds keep the roof clean naturally. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading (measured to ASTM D4214/D2244 standards), so color and finish remain stable. You may rinse debris after storms, but that's optional. This low-maintenance profile means no budgeting for repairs, no contractor calls, and no surprise leaks from material degradation.
How long does metal roofing installation take, and can it go over my existing roof?
Yes, Interlock can install over most existing asphalt roofs without tear-off—eliminating landfill waste and labor cost. Typical installation takes 3–5 days for a single-story home, depending on roof size and complexity. The four-way interlocking system (no visible fasteners) speeds installation and ensures uniform coverage. Interlock Metal Roofing has served the region since 2001, with crews familiar with Wright County homes and weather windows. Over existing roof means minimal interior disruption, no disposal fees, and immediate water protection—the lightweight aluminum panels (0.41–0.59 lb/sq ft) settle easily over the old shingles' solid substrate.
Are metal roofs actually more environmentally friendly than asphalt?
Yes. Interlock panels are approximately 95% recyclable aluminum; at end of life, they return to the aluminum supply chain rather than a landfill. Asphalt shingle tear-offs—needed every 15–20 years in Minnesota's freeze-thaw climate—generate millions of tons of landfill waste annually that never decomposes. By installing a 50-year metal roof (with transferable warranty extending to 100 years of service), Greenfield homeowners prevent 2–3 asphalt-replacement cycles and their associated demolition waste, transport emissions, and landfill burden. The sustainability benefit compounds: one installation replaces multiple short-lived products.
