Standing Seam Metal Roof Pros and Cons in New England

What are the main advantages of standing seam?

The main advantages of a standing seam roof are concealed fasteners, raised seams that keep water away from joints, and long, uninterrupted panels with few places for leaks to start. With no exposed screws in the field of the roof, there are no rubber washers to dry out and loosen over the years. Standing seam is also light. Aluminum panels weigh a small fraction of what slate or multiple asphalt layers do, which helps on older framing. The smooth surface sheds rain quickly, and many solar racking systems clamp to the seams, reducing the number of roof penetrations. Then there is the look. Standing seam has become a favorite on modern farmhouses, coastal contemporaries and new additions throughout New England, and it pairs well with board-and-batten, shingle and clapboard siding.

What are the drawbacks of standing seam?

The main drawbacks of standing seam are cost, oil canning, sliding snow and a look that does not fit every house. It usually costs more than asphalt shingles and many other metal roofing styles because of material, flashing details and the skill it takes to install well. Oil canning is visible waviness in the flat pans between seams. It is cosmetic rather than a leak, but it shows in low-angle morning or evening light. Narrower panels, stiffening ribs, a flat deck and correct clip attachment reduce it. The vertical lines that look sharp on a modern farmhouse can look out of place on a Federal Colonial or an ornate Victorian, and complex roofs with many dormers and valleys need a lot of cutting and custom flashing. Some homeowners prefer a metal roof shaped like slate or cedar for those houses.

How does standing seam handle New England snow and ice?

Standing seam handles snow well because its smooth panels let snow slide off rather than pile up, which shortens how long heavy wet snow sits on the roof after a nor'easter. That is a real benefit on steep roofs in the White Mountains, the Green Mountains and western Maine. The flip side is where that snow goes. A roof full of snow can release all at once onto walkways, entries, decks, cars, shrubs, gutters or a lower roof. Snow guards are a design decision for those areas, and placing them well depends on roof pitch, panel length and what is below. Talk through each eave with your installer. Ice dams are a separate issue. They form when heat escaping from the house melts snow that refreezes at the eaves. No roof prevents them on its own; insulation, air sealing and attic ventilation address the cause.

Is standing seam a good choice on the coast?

Aluminum standing seam is a strong choice on the coast because aluminum does not rust in salt air. On Cape Cod, the Islands, the North Shore, the Rhode Island and Connecticut shoreline and the Maine coast, that matters more than almost any other material property. Steel standing seam relies on its metallic coating and paint to resist corrosion, and cut edges, scratches and fasteners are where coastal problems tend to start. Aluminum removes that particular concern, though the whole system, including clips, fasteners and flashings, still needs compatible materials. Wind matters on the coast too. Standing seam performance in high wind depends on the panel, the clip spacing, the deck and the edge details, so ask for the manufacturer's installation specification and make sure the installer follows it, with extra attention at eaves, rakes and ridges.

Does standing seam suit historic New England homes?

Standing seam can suit some historic New England homes and look wrong on others; it depends on the house and what it originally had. Metal roofs have a long history on porches, barns, outbuildings and some nineteenth-century houses, so on those buildings it can be a natural fit. On a center-chimney Colonial, a Greek Revival in a town center or a Victorian with patterned shingle roofs, a profile that looks like slate or wood may suit the architecture better. Interlock makes Slate, Cedar Shingle and Shake profiles for that reason, alongside Standing Seam. If your house is in a local historic district, check with your local historic district commission before you choose. Commissions differ in how they view metal roofing, and some care about seam spacing, color and edge details as much as the material itself.

Are standing seam roofs worth it?

Standing seam is worth it for many New England homeowners who plan to stay in the house, want low maintenance and like the look, especially on steep, simple roofs and on the coast. It is less compelling on complex, cut-up roofs with many dormers and valleys. The value comes from service life and low upkeep rather than a low upfront price. When you compare quotes, compare the full system: panel material and thickness, seam and attachment type, underlayment, flashing details and the written warranties.
