Metal is an ideal roofing material due to its durability, recyclability, resistance to vegetation growth, light weight and fire resistance. Very popular nowadays, metal roofs are suitable for people who prefer a uniform look or want to have the opportunity to customize the aspect of their roof.
Although metal roofs are more expensive, they come with very few risks, as well as very few maintenance requirements, being a great investment for any type of building.
Metal has been used for a long time in the construction of roofs and has become more and more popular lately due to the advancements in the roofing industry. The oldest metal tiles were made back in the `50s, but metal shingles as we know them today did not appear up until the early 80s. Over time, the technology has evolved greatly, constantly improving performance in terms of durability, corrosion resistance and ability to withstand mechanical shocks. Even metal panel fastening systems have evolved, thus reducing the time required for installation, improving the impermeability and lifespan of the roof system.
Metal shingles are made of steel, a material that is covered with a layer of zinc or a mixture of zinc and aluminum. This layer provides anticorrosive properties and mechanical protection against hail. In general, the outer layer is covered with paint and varnish, these having the role of protecting, but also of offering the possibility to the clients to choose colors and finishes they like. A roofer confirms that some manufacturers also produce stone coated metal shingles, with considerably improved resistance.
Aluminum and copper are also used for metal roofing; they do not rust, but their costs are quite high, being more difficult to install.
Metal roofs are reflective and also provided with a space between the cover and the frame, which acts as a thermal insulation layer (think of the air space between two layers of glass of a double glazing window!). The tests performed revealed that the amount of heat accumulated by a metal roof is reduced by no less than 40%, compared to a regular asphalt shingle roof. In areas with cold climates, however, the roof must be well insulated, to improve its thermal performance.
The most difficult test for a roof is that of resistance in time, a test that metal roofs have passed with flying colors. Such a roof can last for over 50 years, with minimal maintenance. It has high resistance in different climates, due to the properties of the metal from which it is made and the outer layers (zinc, aluminum, volcanic rock, liquid coating). In conclusion, a metal roof made of quality materials, installed by professionals, will not be affected by the weather and will offer you comfort and peace of mind for a long time.
If you are looking for the right solution for your home, a respected local Littleton roofer highly recommends a metal roof, even if it involves a higher upfront cost compared to some other materials, because its exceptional qualities and longevity make it worth the extra money.
