\"metal-roofing\"In almost every case, the answer is yes, you can lay down a new metal roof over an existing shingle roof. This is one of the many reasons metal roofs keep growing in popularity<\/a> \u2013 their installation doesn\u2019t require completely tearing off the existing roof, which is a time-consuming and expensive job.<\/p>\n

Metal, although super-strong, is very light, weighing less than a pound per square foot compared with as much as four pounds per square foot for asphalt shingles. Adding a metal roof over existing shingles doesn\u2019t significantly increase the overall load for the home structure to bear.<\/p>\n

Along with saving the cost of completely removing the existing roof, installing a new metal roof over a current roof also brings the benefit of additional insulation above your home to prevent heat and cool from escaping.<\/p>\n

And since we mentioned insulation, we should also mention that metal roofs are heat-blockers \u2013 they reflect heat away from their surfaces rather than absorb it. This means the extra insulation from your shingle roof will not act as a heat trap for heat emanating through your metal roof.<\/p>\n
