Interlock® Aluminum Roofing — all-climates performance specs for Windsor, Maine
| 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. |

Our house experiences high wind and exposure to the elements on the Maine coast. Interlock offered competitive pricing on aluminum shingle roofing. The entire experience was good, from quotation, removal of the old roof, and installation of the new roof.
We really like our roof.
Interlock was great, and installation was just as told to us by sales. The crew worked hard, cleaned area each day and roof looks great!

Nazar was awesome to fix roof from winter ice damage. !!
Bought this roofing 20 years ago. It was installed well. Needed improvements to my roof structure were suggested and made to ensure the longevity and worthiness of my roof. All these years later I am still happy I made the investment in my 160 year old home.

Interlock was very professional. They installed my roof in a timely manner and the workmanship was great. Glad I went with interlock. Positive: Responsiveness, Punctuality, Quality, Professionalism, Value Services: Roof damage repair, Roof installation
Positive: Professionalism, Punctuality, Quality, Responsiveness, Value To Potential Interlock Customer: We intentionally waited almost two years to write a review (roof replaced in August 2019). Replacing a roof (whether asphalt or Interlock) is an expensive project, and we felt it was important to have the perspective of someone who has experience with the Interlock roof for 2 years. Our house is an old colonial built in about 1890. It is almost 3200 square feet with an attic that could be converted to a third floor. We also have an L-shaped wrap-around porch at the front of the house. I am very familiar with the effort it takes to replace a roof, as I have helped re-roof five different houses, including my own. I did this with the help of several friends, putting a layer of asphalt shingles on my house about 20 years ago. However, after 20 years, I had shingles beginning to fail and lost a couple during wind storms. I had a couple of asphalt shingle contractors look at the house for an estimate. One never provided a quote. The second refused the work because my house is 34 feet at the peak, and he felt it was too tall for him to work on. Michael Baldarassi came to our house in June 2019. I found him to be extremely knowledgeable about the construction of old houses and correctly identified that the gable ends would need repair as it was common to not fully extend roof boards to the gable end. He explained the product extremely well, and we were happy to choose the black, " data-wpil-keyword-link="linked">slate-looking tiles for our roof. The work team started in the second week of August on a bright sunny, " data-wpil-keyword-link="linked">hot week. My roof needed to be stripped to the boards, and I was amazed at how quickly they dealt with the very hot asphalt shingles. It is an extremely hard-working team, and it was to the point that I wanted to tell them to take breaks. Sheets of plywood were carried up to the roof, gable ends were repaired, and several spots needed repair prior to installing the Interlock shingles. They did an excellent installation, along with cleanup and the weather-supported completion in 5 days. We immediately started receiving compliments from townspeople who thought we were having a slate roof put on. The roof definitely adds appeal to our house. Our experience with the Interlock roof has been outstanding. I no longer worry during the strong winds of winter. Having the snow slide off the roof has been a big benefit. Our first snowstorm in December 2019 was 20 inches. It was predicted to be followed by rain four days later. For the past 20 years, I have had to go out onto the wrap-around porch roof to shovel it off so that the 20 inches of snow with rain on it wouldn’t overload the porch. Not with Interlock. The snow had slid off during the snowstorm and before the rain, so no more shovelling the roof. I love not having to stand on a snowy roof shovelling anymore. Having the snow slide off has other benefits. It removed tons of weight from the snow on the roof. That snow weight does nothing good for a house. I used to have minor changes in door fitting, etc., during the winter, but that has stopped because the snow weight on the roof is gone. Additionally, no snow on the roof means no icicles. As one side of my house faces the sun all day, there are winters where if it is 10F and sunny for several days, massive icicles form that weigh hundreds of pounds. These become dangerous when they unexpectedly drop. Icicles do not happen when there is no snow on the roof. Our Interlock roof has been a fantastic choice, and it has added to the value of our house. One day when we sell our house, I have no doubt that our Interlock roof will help to attract a buyer, and the price of the roof will likely be recouped in part or all. What is a big question a potential homebuyer has? - how old is the roof? Being able to answer with a 50-year " data-wpil-keyword-link="linked">warranty that can be transferred to one buyer will bring a lot of weight to the sale. The warranty gives us peace of mind that the roof will never worry us again. Thank you again, Interlock. Service: Roof installation
All of the above...we had a positive experience and live the look of our roof.

Metal Roofing FAQs for Homeowners in Windsor
The following metal roofing FAQs are designed specifically for homeowners in Windsor, Maine. 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 Windsor.
How does a metal roof handle Maine's heavy snow and ice buildup?
Metal's smooth, hard surface sheds snow and ice far better than asphalt shingles, reducing dangerous accumulation and ice-dam pressure. Windsor receives about 148 cm of snow annually, and freeze-thaw cycles occur roughly 94 times per year—conditions that crack and curl asphalt over time. Interlock's four-way interlocking aluminum panels lock together so tightly that wind-driven snow cannot infiltrate seams. The panels resist thermal cycling without splitting or warping. Snow guards are available if you want to retain snow for insulation or prevent sliding onto walkways.
Will freeze-thaw cycles damage an aluminum metal roof in Windsor's climate?
No. Aluminum has no iron content and cannot rust, and its oxide layer self-heals when scratched—so repeated freezing and thawing causes no degradation. Asphalt and wood shingles crack under the same freeze-thaw stress that Windsor experiences 94 times per year. Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloys are ASTM B209 certified and retain their structural integrity indefinitely. The Alunar 70% PVDF coating is independently tested to resist chalking and fading for 30 years, staying flexible even during Maine's temperature swings.
Can a metal roof withstand Windsor's winter and spring wind gusts?
Yes. Windsor experiences typical gusts up to 127 km/h, and Interlock panels are warranted to resist winds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking design locks each panel to its neighbors on all edges, preventing wind from lifting or separating them. This is far superior to asphalt shingles, which rely only on nails and sealant. ICC-ES evaluation ESR-1790 documents the panel's compliance with IBC/IRC wind load standards. Proper installation by Interlock Metal Roofing (New England) Inc. ensures your system meets or exceeds all local building codes.
What is Interlock's hail rating, and does it affect insurance?
Interlock metal roofing earns the highest available hail impact rating: UL 2218 Class 4, the same standard that requires resistance to steel balls dropped from increasing heights. The warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize Class 4 impact ratings and offer discounts on premiums. Aluminum's density and hardness absorb impact energy without denting permanently or losing integrity. In Maine's severe weather seasons, this resilience reduces both physical damage and long-term maintenance costs compared to asphalt or wood shingles, which dent, split, or lose granules after hail events.
Do I need to reinforce my roof structure for a metal roof?
No. Interlock's aluminum panels are extraordinarily light—the Slate installs at just 0.41 lb/sq ft, and the Mediterranean Tile profile weighs only 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. Most existing roof framing easily supports this weight, so structural reinforcement is rarely necessary. This also means Interlock installs directly over most existing asphalt roofs, eliminating costly and wasteful tear-off and disposal. Because Windsor receives about 148 cm of snow annually, weight efficiency is practical: the metal roof itself adds minimal dead load, so snow load capacity remains high and your home's foundation shoulders less burden.
How much maintenance does a metal roof really need?
Minimal. Interlock aluminum panels require no painting, sealing, or granule replacement—tasks that consume time and money on asphalt or wood roofs. Occasional gutter cleaning and inspection of flashing are standard for any roof. The non-porous aluminum surface resists algae and mold better than asphalt or wood, and the Alunar 70% PVDF coating is CALGreen-verified for reduced maintenance. Windsor's 930 mm annual rainfall and 2977 sunshine hours mean your roof experiences heavy washdown and UV exposure; the coating's 30-year warranty against chalking and fading reflects real-world durability. Most homeowners report they never have to climb the roof after installation.
Is a metal roof worth the upfront cost over asphalt?
Yes, when you calculate total cost of ownership over the roof's life. Asphalt shingles typically last 15–20 years and require costly tear-offs and disposal; Windsor's freeze-thaw cycling (94 days per year) accelerates that degradation. Interlock's lifetime limited warranty from The Guardian covers rusting, rotting, splitting, cracking, and curling—the failures that drive replacement cycles. The warranty transfers once, giving the next owner 50 years of protection. Current financing includes no payments and no interest until Spring 2027, or 10% off installation. Over 40–50 years, one durable roof beats two or three asphalt replacements, plus avoided labor, landfill fees, and structural damage from leaks.
Is aluminum roofing actually more sustainable than asphalt?
Yes. Interlock's roofing-grade aluminum is approximately 95% recyclable at end of life, so it cycles back into manufacturing rather than a landfill. Asphalt tear-offs and disposal create tons of waste and transportation emissions yearly. The aluminum panels are manufactured in Delta, BC since 1998, reducing transport distance compared to distant suppliers. At installation, Interlock often fits over your existing roof, eliminating tear-off waste entirely. Windsor's 930 mm annual rainfall and freeze-thaw stress make asphalt roofs fail faster, driving more frequent replacements and higher landfill burden. One aluminum roof avoids multiple asphalt replacements, reducing your home's lifecycle environmental impact significantly.
What does the metal roof installation process look like?
Interlock Metal Roofing (New England) Inc. begins with a site inspection and measurements, then confirms your existing structure can support the installation—often no reinforcement is needed due to aluminum's light weight (0.41–0.59 lb/sq ft). The contractor typically installs over your existing roof, avoiding costly tear-off and debris removal. Panels install in courses, with each locked four-way to its neighbors. Flashing, gutters, and trim are sealed with high-quality sealant. Installation usually takes 3–5 days for a typical residential roof, depending on complexity and weather. Because Windsor experiences about 2977 sunshine hours annually, crews can often complete the job without extended weather delays. Your local installer has served the region since 1999.
Is a metal roof fireproof, and does it affect my insurance?
Aluminum is non-combustible and does not burn. Interlock metal roofing is available with Class A fire classification, the highest rating under the ASTM E84 test standard, and complies with ICC-ES evaluation ESR-1790 (reissued 2025) and CALGreen requirements. This means it will not ignite or spread flame, protecting your home and potentially lowering fire insurance premiums. Many insurers recognize Class A ratings and offer discounts. In regions with wildfire risk or high fire-danger zones, Class A roofing is often required by code. Even in lower-risk areas like Windsor, the non-combustible rating adds long-term safety and resale appeal, eliminating one major failure mode that asphalt and wood roofs cannot match.
