Interlock® Aluminum Roofing — all-climates performance specs for Forest Lake Junction, 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.) |

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 Forest Lake Junction
The following metal roofing FAQs are designed specifically for homeowners in Forest Lake Junction, 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 Forest Lake Junction.
How does a metal roof handle Forest Lake Junction's winter snow and freeze-thaw cycles?
Interlock's four-way interlocking aluminum panels shed snow effectively because the smooth, slippery surface prevents ice dams that trap water behind debris — a critical advantage given Forest Lake Junction's average 92 cm of annual snowfall and 83 freeze-thaw days per year. The aluminum alloy (3105-H24) remains dimensionally stable across temperature swings, unlike asphalt or wood shakes that crack and curl. Snow guards are available if you prefer to manage snow retention. The panel's lightweight construction (Slate at 0.41 lb/sq ft) means no structural reinforcement is needed, even in heavy snow years.
Why won't an aluminum metal roof rust, and does that matter in Minnesota?
Aluminum physically cannot rust because it contains no iron — instead, a thin, self-healing oxide layer forms instantly when the bare metal is exposed to air, sealing it against further corrosion. In Forest Lake Junction's climate of high humidity, rain (778 mm annually), and freeze-thaw stress (83 days per year), this distinction is decisive. Steel alternatives require paint maintenance to prevent rust bloom. Interlock panels are coated both sides with Alunar 70% PVDF fluorocarbon (warranted 30 years against chalking and fading per ASTM D4214), providing an extra shield that aluminum's chemistry doesn't require but benefits from in wet climates.
Can freeze-thaw cycles damage an aluminum metal roof?
No, freeze-thaw cycles do not damage roofing-grade 3105-H24 aluminum alloy because aluminum's crystalline structure does not absorb water and expand — it simply cycles with temperature without internal stress. Forest Lake Junction experiences approximately 83 freeze-thaw days annually, a regime that destroys asphalt (which embrittles and cracks) and wood shakes (which split and cup). Aluminum panels retain their integrity through these swings indefinitely. The Alunar coating, warrantied 30 years, provides additional protection, and the interlocking seams (ICC-ES ESR-1790 compliant) prevent water infiltration that would otherwise pool in micro-cracks.
Will a metal roof hold up to Minnesota wind gusts?
Yes — Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification, far exceeding Forest Lake Junction's typical gusts of 100 km/h. The mechanical interlock between adjacent panels distributes wind load across the entire roof plane rather than relying on fasteners alone, which is why UL testing validates the system at Class 4 impact (UL 2218). Installation over solid decking with continuous nailing ensures no uplift. Spring wind events and severe gusts common to Washington County pose no structural risk to properly installed Interlock panels.
Can an existing house structure support a metal roof, or do I need reinforcement?
No reinforcement is required for Interlock aluminum roofing. The Slate profile weighs just 0.41 lb/sq ft, the Shake 0.58, and even the Mediterranean Tile — which replicates the look of heavy clay or concrete tile — weighs only 0.59 lb/sq ft, approximately 96% lighter than real tile. This means most homes can install Interlock over their existing roof without structural modification, saving tens of thousands in framing costs. A structural engineer will confirm your deck is adequate for normal roof loads (30–50 psf snow load); aluminum's featherweight character means existing framing built for asphalt shingles handles it easily, even across Forest Lake Junction's potential 92 cm winter snow accumulation.
What maintenance does an aluminum metal roof need?
Interlock aluminum roofs require significantly less maintenance than asphalt, wood, or tile. Twice-yearly gutter cleaning and occasional rinsing of heavy pollen or salt spray (if nearby) is sufficient; the panel profiles drain well and do not trap debris. Unlike asphalt, which needs re-sealing and shingle replacement, wood shakes that split and rot, or tile that cracks, aluminum neither absorbs water nor deteriorates. Forest Lake Junction's 778 mm annual rainfall and freeze-thaw environment (83 days per year) would cause asphalt to degrade rapidly; Interlock's sealed, interlocking construction and Alunar PVDF coating remain CALGreen-verified for reduced maintenance throughout the roof's life. No pressure washing, no algae, no structural repairs.
Do aluminum metal roofs help lower cooling costs in Minnesota?
In Forest Lake Junction's climate of 3113 annual sunshine hours and modest summer heat, energy-efficient Interlock colors reflect solar heat more effectively than asphalt, lowering cooling costs and reducing thermal stress on the roof structure. Emissivity reaches 0.84 and solar reflectance up to 0.55 (Aged Copper Penny), meaning less heat is absorbed and re-radiated downward. While Minnesota summers are mild compared to southern regions, this reflectivity extends the life of ventilation systems and reduces attic temperature swings. The Cool Roof Rating Council certification ensures these values persist: the Alunar 70% PVDF coating (30-year warranty) maintains color stability and reflectance, unlike asphalt that oxidizes and darkens over time, reducing reflectance and increasing heat absorption.
Does a metal roof hold up to hail, and can it lower my insurance costs?
Interlock aluminum panels are rated UL 2218 Class 4, the highest impact classification available, and the Guardian warranty even covers perforation from hailstones up to 1.5 inches — an exceptional safeguard. Aluminum's hardness and the solid interlocking structure distribute impact energy rather than denting and cracking like asphalt or tile. Many insurers offer premium discounts for Class 4-rated roofs because claims are rare. Forest Lake Junction's typical wind gusts (100 km/h) can accompany hail, but the panel's four-way interlock and 120 mph wind warranty mean the roof stays intact under both stresses. Document the UL 2218 Class 4 rating when requesting an insurance review — this single specification often qualifies homeowners for discounts.
How long does it take to install a metal roof, and can you install it over my old roof?
Interlock aluminum panels install quickly — typically 2–5 days for a standard residential roof, depending on size and complexity. The exceptional lightness (Slate at 0.41 lb/sq ft) makes handling and fastening faster than slate, tile, or standing seam alternatives. Yes, installation over an existing roof is possible when the deck is sound: no tear-off means no labor, no disposal costs, and no days of exposure to Forest Lake Junction's rain (778 mm annually) or wind gusts (100 km/h). Local Interlock Metal Roofing installers verify deck condition and add appropriate underlayment. Installing over existing roofing reduces timeline and logistics while maintaining a fully sealed, interlocking weatherproof system compliant with ICC-ES ESR-1790 codes.
What's the warranty on an Interlock metal roof, and is it transferable?
The Guardian warranty is a lifetime limited, non-prorated material warranty to the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance — no depreciation over time. The next owner receives a 50-year term from installation completion, making Interlock a one-time roof investment that preserves resale appeal. The Alunar PVDF coating is separately warranted 30 years against chalking and fading (ASTM D4214, D2244 measured), protecting color stability through Forest Lake Junction's 3113 sunshine hours annually. A typical asphalt roof lasts 15–20 years in this climate and requires replacement; Interlock eliminates the cycle of tear-offs to landfills and the financial burden of re-roofing every two decades. This is genuinely the last roof you'll install.
