People usually prefer steel metal roofing because steel roofs are economical and can withstand extreme weather conditions like heavy rain, scorching heat, occasional hailstorms, and wind of more than 100mph.

If you install them properly, these steel roofs will have a lifespan of 30 to 50 years or more. Other metal roofs like copper are more costly but also have many advantages. For instance, you don’t have to apply paint on copper metal roofs because they don’t rust.

People nowadays typically don’t use tin directly as metal roofing, as tin roofs rust easily. Instead, the popular new choice is tin coated with steel.

Aluminum metal roofs are very light and usually prone to dents. Aluminum metal roofs should not be used in areas that regularly receive snowfall.

You should always make sure you have a ladder you can access easily from the roof for safety purposes. Having the ladder present and secure will give you peace of mind and make your work easier.
