Installing a metal roof is a time-consuming procedure that requires attention to many aspects. Although it's possible that a metal roof's failure is due to its nature, it's more likely that it's due to installation issues. Improper installation can result in leaking, a substantial reduction in life expectancy, and even damage to the entire system. The following are some of the most common installation errors and how to prevent them.

One of the first steps in ensuring a good metal roof installation is to accurately and precisely calculate the roof length and slope. If each panel isn't cut to the exact size, the rough edges would be exposed to the elements, resulting in corrosion and roof coating failure. Metal roof panels are available in several different thicknesses, sizes, and profiles. To achieve panels that mold to roof contours and provide a weather-tight fit, "measure twice, cut once."
