So you would like to roof your house with some sort of metal roofing. Not a bad idea but still you have lots of decisions to make. You must ask yourself couple of questions:
1.) what durability do you require from your metal roofing material?
2.) is your desired roofing material in harmony (or adjustable) with/to the other roof paraphernalia (gutters, chimney caps, snow guards)?
3.! how much are you ready to pay?
The aluminum roofing has some advantages you cannot just omit: The aluminum roofing is available in all the required forms/shapes (well, as well as the steel roofing or copper roofing, I have to admit, its the general advantage of all roofing metals, that they can be molded into almost any shape); you can use the aluminum roofing panels, aluminum roofing shingles or aluminum roofing sheets.
Aluminum is a light-weight material, causes no health problems, does not corrode and therefor presents no contamination risk for the rain water. Varnishings used for this type of metal roofing are organic and medically non-problematic as well.
Aluminum is a very stable element suitable for any outdoor conditions. Its minimum durability is 50+ years (if your aluminum roofing contractor states something else, just go to another), and it could be well recycled. In fact, aluminum is the most ecological metal ever, as it can be 100% recycled and using then recycled aluminum you save about 96% of energy needed to produce the new aluminum.
The aluminum roofs offer: – roof stability; – the aluminum roofing shingles are light-weight; – newest ever roof shingle coloring processes (epoxi-polyester cover powders); – chemical stability, its the corrosion-proof material; – no protective penetrating paintings are necessary.
The aluminum vs. steel roofing: – The price of aluminum (Al) roofing is higher; even though not as high as of the copper roofing, but its 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 dont 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.
OK, the moral of this story is – if you have a good aluminum roofing contractor at hand just do not waste your time with steel. If not, you should consider steel, rubber or asphalt to be YOUR roofing materials.
