Far from the often dented tin roofs that adorned warehouses of the past, metal roofs have come a long way. To be sure, only recently, roofing choices, for the typical homeowner, were limited to asphalt shingles or rolls. Commercially, roofs have consisted of many alternative materials, but these were largely out of the reach of the middle class.
- Stable cost: Being comprised of far fewer materials than asphalt shingles, the cost of metal roof tends not to vary as much as conventional roofing shingles.
- Fewer weak points: Because metal roof seams run vertically and not horizontally, there are less total seams — which are typically a roof’s weakest point — and the ones that are there are raised above the level of the roof panel.
- Increased durability: Less likely to be damaged by sun, wind and rain, metal roofs are historically more durable than asphalt shingles.
- Aesthetic appeal: Metal roofs tend to give a house a very modern look.
- A “Cool Roof”: Because metal roofing can be painted any color, it is classified as a “cool roof” by the US Environmental Protection Agency.
- Higher cost: Often finding a contractor willing to install metal roofing can be a challenges and for that reason, the cost can be greater than conventional roofing.
- Not appropriate for every roof: Not advisable for roofs with a pitch of 2:12 or less (2 feet of vertical rise for every 12 feet of horizontal rise), standing seam metal roofs may not work for roofs with a high slope.
- Non-traditional look: Some homeowners will be deterred by the industrial look of a metal roof, as the more earthy colors associated with less modern houses may not be available.
