Classification of roof depends upon the material which is inside the surface which can ignite in intense heat. Most of the metal roofing is applied over combustible materials like wood shingles which have a lower fire rating of class C.

  • Heat conduction

Metal will generally reflect heat from the sun and it will minimize the midday heat intake. This means that it will improve the energy efficiency of your home and reduce the energy bills on air conditioning units. However this material is itself is low on R- value of insulation as many of the system is utilizing dead air space between rood deck and metal for increasing energy efficiency.


  • Cost

But anyways this material has a really long lasting durability and hence the whole high costing can be covered up as it don’t need replacement and last for lifetime.

There are certain types which are guaranteed that they will not dent but you still have to remain conscious and not to walk on the roof. Even in the cases of chimney cleaning and occasions of plumbing, you cannot walk on all the types of metal roofing.

  • Expansion and contraction

Metal is a material which expands and contracts when it warms and cools. Many of the new products possess fastening system which accommodates movement or else fasteners which secure the roofing will tend to become loose. Along with that contraction and expansion on hot days can also cause wavy effect.

  • Modifications

Metal roofing materials are such which are installed in large panels and hence it becomes very much difficult to replace them when they get damaged.
