- The price of aluminum (Al) roofing is higher; even though not as high as of the copper roofing, but it´s still too expensive when compared to the steel roofing shingles; - To be honest, the installation price of the aluminum shingles or sheet usually discourages the DIY roofer from using it, but the homeowners are wrong. When just put in the juxtaposition, in 10 years, the aluminum is even more economical roofing material than the steel. Do not forget that all the protective paintings are not necessary with aluminum, and over years it makes more than enough; - performance of both aluminum and steel roofing materials is the same providing that the steel shingles or sheets are maintained with penetrating anti-rust dyes each 3-4 years (based on the weather conditions). With aluminum, you don´t have to climb your roof for much longer time (the promised 50+ years); - aluminum roofing sheets are little thicker than the steel roofing sheets, but who cares… the weight is the same.
