Higher upfront cost
The most significant drawback is cost. Metal roofing generally costs more upfront than asphalt shingles — both for the material and for the installation, which is more specialised. The exact difference depends on the product, the roof's size and complexity, and the contractor. Standing-seam systems generally cost more than corrugated panels, and copper and zinc cost more than steel or aluminium. Our guide to roof replacement cost factors explains the other factors that affect a replacement's cost. The higher upfront cost can be offset over time by the longer lifespan, but only if you stay in the home long enough to benefit from it.
More specialised installation
Metal roofing needs to be installed by someone experienced with the material. Panels need to be cut, fitted, and fastened correctly, and the details around valleys, ridges, chimneys, and skylights need careful flashing. Poor installation can lead to leaks, noise, or panels that do not perform as they should. That is why it is worth asking a roofing professional about their experience with metal roofing specifically, not just roofing in general. See our guide to roofing contractor red flags for warning signs to watch for.
Noise in heavy rain
A common concern is noise. Rain on a metal roof can be louder than rain on a shingle roof, especially in heavy rain. With proper underlayment, insulation, and the roof deck underneath, the noise is often less noticeable than people expect, but it can still be a factor, particularly in a home with little insulation above the living space. If noise is a concern, ask the roofing professional about the underlayment and insulation that will be used.
Denting from hail and falling branches
Metal can dent in hail, especially thinner metal, and can be dented by falling branches or other debris. Small dents are often cosmetic, but larger dents, or dents that break the protective coating, can be a concern, because a broken coating can lead to corrosion. Hail damage on a metal roof is often easier to see than on shingles, because the dents are visible — see our guide to hail damage signs. The type and thickness of the metal affect how easily it dents, so ask about the gauge (thickness) of the product you are considering.
Repairs can be more involved
A damaged metal panel may need to be replaced, and matching the existing panel — in colour, profile, and coating — can be harder than matching a shingle, especially if the product is older or discontinued. Repairs can also be more specialised, and not every roofing professional works with metal. If you choose a metal roof, it is worth asking how repairs are handled and how easy it is to source matching panels later.
Appearance and neighbourhood fit
Metal roofing has a distinct look, and it does not suit every home or every neighbourhood. Some homeowners love the clean, modern look of standing-seam panels; others prefer the more traditional look of shingles. Metal shingles and tiles that mimic other materials can bridge the gap, but they generally cost more. It is worth looking at homes in your area with metal roofing, and considering the style of your house, before deciding.
