What to Know Before Buying Metal Shingles What to Know Before Buying Metal Shingles

The installation of metal shingles is unlike other types of shingle installation. Choosing to install a metal roof with metal shingles requires in-depth knowledge on how the shingles work and what problems may occur after improper installation.

Thermal Movement

Metal shingles are extremely durable and flexible. They can provide a lifetime of protection, with little periodic follow-up care. This requires that the shingles be properly installed initially to take into account shifts or thermal movement that occurs as the weather changes. The metal expands and contracts as the temperature goes from hot to cold. This movement must be accounted for when the shingles are attached to the roof.

Types of Shingles

There are a variety of types of metal shingles available on the market. They can come as stone-coated steal, copper, aluminum and other metal alloys that can be made to look like traditional organic asphalt shingles. The type of shingles you should choose depends on many factors including your budget, color preference, installation expertise (if installing yourself) and the durability of the shingles.

The good thing about the different types of metal shingles is that they do not curl up after installation like asphalt tiles do. They are also resistant to algae, fungus, mold and other bacterial growth. Finally they are non-combustible so metal shingles do not present a fire hazard for the home.
