Different metals undergo varying amounts of expansion and contraction during summers and winters respectively. The surface of the metal undergoes any change in dimension due to change in temperature, the first. This may lead to the cracking of the paint. As soon as there is a change in temperature, it will cause a considerable change in the dimension of the metal roof depending on the time of the day and the weather of the year.

It is important that the paint has the same expansion and contraction as that of the metal roof. This will prevent the paint from leaving the metal surface due to the difference in the expansion coefficient of the two. If the coefficients of expansion are not similar, the paint may crack and chip off. This expansion should be same for the primer as well as the top coat for a better life of the paint.
  • Choose the right paint: for the paint to last long, you must choose the right kind of paint for metal roof painting mi. It is always better to choose acrylic paints that are water-based.
