Belmont, MA Aluminum Shingles Review: Interlock Roof Installation, Service Challenges, and Updated Experience

Belmont, MA

David M.

Based on my original review below, Interlock reached out and was explicit about wanting to know what needed to be done to receive a better review. My experience with Interlock since that point has been excellent.

First, the customer service person (Jen) became very responsive. The technician (who I had positive things to say about below) continued to be knowledgeable and focused on doing the job right. The technician applied new caulking around the chimney, alerted me to issues with the chimney cap (not in scope), and completely re-installed the flashing where our original house meets a lower roof (what was the issue resulting in significant exterior, structural wall damage). The technician explained that installation methods for the Interlock product have changed over the years and what was installed originally is no longer the way flashing is installed today.

This latest set of interactions with Interlock gives me greater confidence that we would continue to use Interlock for any additions to the house needing roofing (e.g., a portico over the front door, an addition over the garage). If their current technician in the Boston area is an indication of current install quality, then you will have no issues or complaints about the product. I just feel badly for all the folks with older Interlock roofs, like me, where installation methods were unacceptable.

Original Review:

We bought a house with an Interlock roof. I really want to like Interlock. It seems like a nice product. Unfortunately, the roof installation cut proverbial corners and getting service for the roof has been extremely difficult.

For the sake of giving credit where due, their roofer that collaborated with our solar installer was competent. Sadly that is not universally the case.

When we first moved in, one of the first things I noticed was that the metal roof installation, over an existing composite roof, makes the unfortunate assumption that the flashing under the old roof is in good shape and will continue to operate. As such on one section of roof that abuts the main house, the flashing was fastened to the side of the wood siding, allowing rain running down the side of the house to go behind the flashing down to, theoretically, the original roof and flashing. Another roof that abuts the main house was installed by Interlock without flashing by shoving it up under the wood siding. This has expedited wood rot of the siding and has not prevented water leaks that completely rotted a significant portion of the exterior wall of the main house. It is crazy to me that anyone would install a roof without ensuring it is flashed properly.

Beyond that, trying to work with Interlock to collaborate with our solar installer was a very painful process. Due to Interlock not reading the solar installation plans or passing them along to their roofer, they were not prepared to help with the solar rail installation, leading the solar installer to have to eat the cost of a crew of 8 people that could not do the install as planned as the right roof flashing was not available. Thank goodness the Interlock roofer was willing to not proceed without the right flashing, but it would have been better had the right preparation been made.

There is now a leak around the chimney of the house. I have been trying to schedule service with Interlock for over a month and a half. Their “system” has been down for over two months so they cannot find records regarding the roof on my house. They have also been unable to schedule me for service, consistently passing messages along to a local affiliate of some sort that keeps telling me that they can’t schedule for service until their system comes back up.

I hope I can eventually update this post with some good news, but as of right now I have a list of reasons you should avoid this company.

Top 10 Metal Roofing FAQs for Homeowners in Belmont

Homeowners researching metal roofing in Belmont often have several important questions before replacing their roof. Many people want to understand how metal roofing compares to traditional materials like asphalt shingles in terms of lifespan, durability, cost, and long-term value. Roofing decisions can also be influenced by local weather conditions. Homes in Belmont may experience environmental factors such as rain, wind, snow, heat, fire, or seasonal storms that can impact roof performance over time. The following frequently asked questions help explain what homeowners should know when evaluating metal roofing and why many people choose durable roofing systems designed for long-term protection.

Metal roofs in Belmont commonly last 40–70+ years, while asphalt shingles typically have shorter lifespans (often 15–30 years). Belmont experiences significant annual precipitation and snowy winters—roughly ~49 in. of rain and ~50+ in. of snow on average—which drives heavy snow loads and frequent freeze–thaw cycles that accelerate wear on roofing materials. These local factors (snow loads, ice dams, repeated freeze–thaw and steady rainfall) favor long-lasting, low-maintenance systems: metal sheds snow, resists moisture-related degradation better than asphalt, and stands up to wind and winter stress. Homeowners choose durable metal roofs to reduce replacement frequency and ice-dam maintenance. Interlock Metal Roofing systems use heavy-gauge aluminum and include a lifetime limited 50-year transferable warranty designed for long-term protection.
Metal roofs in Belmont generally cost more up front than asphalt shingles, but final price depends on roof size, slope, complexity, tear-off, flashing, skylights, and local labor and permitting. Durable metal systems often reduce future repair and replacement costs, so many homeowners weigh lifetime value over initial price. Local factors to consider: Belmont experiences cold, snowy winters with substantial snowfall and frequent freeze–thaw cycles—conditions that increase snow loads, ice-dam risk, and demand for robust flashing and roof ventilation. Those conditions can raise installation complexity and material choices (standing seam, thicker gauges, snow guards), affecting cost. Interlock Metal Roofing focuses on long-term ownership value—providing durable systems and proper detailing that lower lifetime costs rather than competing as the lowest‑cost option up front.
Short answer: Yes—often, for Belmont homeowners who prioritize durability and long-term protection, metal roofing is worth the higher upfront cost compared with asphalt shingles. Belmont experiences cold, snowy winters with frequent freeze–thaw cycles and regular precipitation/humidity that can accelerate shingle wear and encourage moss in shaded areas. Differences: • Lifespan: Metal typically lasts 40+ years (often 50–70); asphalt usually 15–30. • Maintenance: Metal needs less frequent repair and resists ice/damage; shingles require more inspections, sealing, and moss/algae control. • Durability: Metal better resists snow loads, freeze–thaw stress and wind; shingles are more vulnerable to granule loss and ice dam damage. • Long-term value: Higher initial cost for metal but lower lifetime maintenance/replacement costs—better value if you plan to stay long term. Interlock Metal Roofing systems appeal to homeowners seeking long-term performance and architectural curb appeal because they pair engineered durability with lifetime warranties and finished looks tailored for New England conditions.
Is a metal roof noisy when it rains in Belmont, MA? This is a common myth. Modern residential metal roofs installed over solid decking with proper underlayment and insulation do not sound like barn roofs. The perceived noise level depends on the roof assembly—insulation, attic space, underlayment, and ventilation all absorb and dampen sound. Quality of installation and fastening methods matter; poor installation can increase vibration and noise. Properly installed residential metal roofs are typically similar in sound to asphalt, tile, or composite roofs. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes, incorporating deck attachment, underlayment, and ventilation to minimize noise.
In Belmont, MA, a metal roof can be energy efficient because reflective coatings and light-colored panels reduce solar heat gain, lowering summer cooling loads. Actual savings depend on the full roof assembly — underlayment, insulation levels, and attic ventilation — which together control heat transfer and moisture management. Belmont’s seasonal swings mean reflective benefits are useful in summer, while insulation and airtight details matter more in winter. Homeowners researching a roof replacement often weigh energy efficiency to reduce utility bills, improve year‑round comfort, extend roof and HVAC life, and increase resale value (and to qualify for local incentives). Proper color selection and professional installation further improve outcomes. Interlock Metal Roofing systems are designed to support long-term home performance.
Belmont, MA roofs face nor’easters, heavy snow, strong seasonal and coastal wind gusts, and occasional hail and thunderstorms—weather that commonly stresses roof coverings and flashings. Metal roofing can perform very well: interlocking or mechanically-seamed panels resist wind uplift, standing seams shed snow and water, and thicker gauges or impact-rated finishes reduce hail damage. Performance depends on: • roofing system design (panel profile, seams, underlayment) • installation quality (fasteners, flashing, attachment) • material durability (gauge, coating, warranty) Homeowners consider weather resilience to avoid leaks, reduce repair/insurance costs, and extend service life. Interlock Metal Roofing systems are engineered for durability, hail protection, and wind resistance, but achieve best results only with proper design and professional installation.
Corrosion and rust resistance in Belmont, MA: Metal roofing performance depends on the metal—steel, galvalume, copper, zinc, and aluminum each behave differently. Materials with natural oxide layers or corrosion-resistant alloys (aluminum, copper, stainless steel) resist rust better than plain steel. Aluminum is especially well-suited for wet or coastal environments because it forms a protective oxide film, resists saltwater corrosion, and won’t develop iron-based rust. Homeowners should prioritize corrosion resistance to extend roof life, reduce maintenance and repair costs, maintain appearance, and protect home value—especially in Massachusetts’ humid and coastal microclimates. Interlock Metal Roofing systems use aluminum construction engineered for strong corrosion resistance and are further protected by the Alunar Coating System for extra durability and long-term performance.
Metal roofing in Belmont, Massachusetts is generally low maintenance: durable panels and standing seams resist rot, pests and many leak causes. However, no roof is completely maintenance‑free. Homeowners should inspect roofs periodically—after major storms and seasonally—for loose fasteners, damaged flashing, clogged gutters, and buildup of leaves, needles or branches. Pay special attention to roof penetrations (chimneys, vents, skylights) and perimeter flashing where leaks often start. Remove debris, keep gutters flowing, and arrange professional checks after wind, ice or heavy snow events. With proper occasional care, metal roofs offer a long‑lasting, low‑maintenance choice well suited to Belmont’s New England weather. They provide strong value over time.
Yes — in Belmont, MA, metal roofing can increase a home’s resale value. Buyers often prioritize durable, low‑maintenance roofs, so a metal roof that resists weather and reduces upkeep is attractive. Premium materials and finishes also enhance curb appeal, which matters in Belmont’s established neighborhoods. The long lifespan and warranty of quality metal systems boost buyer confidence and can justify higher asking prices. However, architectural style matters: a metal roof should complement the neighborhood’s character and local historic homes to maximize value. Interlock Metal Roofing systems offer multiple architectural profiles—slate, cedar shingle, Mediterranean tile, shake, and standing seam—in heavy‑gauge aluminum and solid copper, enabling both visual fit and long-term performance. Local appraisal impact varies.
Yes. Interlock Metal Roofing systems accept solar panels when fitted with custom solar brackets installed by Interlock Metal Roofing – New England. Belmont averages about 49 in of precipitation and roughly 53 in of snow annually, which increases moisture exposure and snow/ice loading on roofs. Winters are cold and often snowy, driving freeze–thaw cycles that stress roof materials. Because panels last decades, roof lifespan matters: choose long-lasting materials (like Interlock metal) and plan for solar when re‑roofing to avoid removing panels later. Interlock systems are solar‑compatible and designed to support solar mounting solutions.
