While a typical asphalt or traditional tile or slate roofing will certainly need repairing or re-installing every 10-15 years, a metal roof, if properly installed, can last for as much as 50 years or even more. Metal roofs are able to withstand virtually anything that Mother Nature can throw at them. Compared to other kinds of roofs, there truly is no contest with regards to strength and durability. Most metal roofs include extended warranties for up to 30 years, and if you decide to recoat it then you'll most likely never be required to repair it in your lifetime.
Metal Roof Types:
Probably the most common type of metal roof is made from steel. Being the most developed metal industries, steel is a great option as it provides strength and flexibility, it is reasonably priced and it truly is excellent for any kind of building be it residential, industrial or commercial roof repairs. Even though other (much more costly) types of stainless steel are at times used on high end developments like commercial buildings, usually use galvanized steel.
Tin roofing has quite a long history in North America. Tin smith craftsmen used to do a roaring trade in tin roofs for residential properties for a lot of years although they're much less common now. Some are still installed, but tin is nowhere close to as durable as other types of metal, steel for instance, and needs to be coated on a regular basis as a way to preserve their condition and stop them from corroding.
Most likely the longest lasting metal roof material, aluminum can last longer than even the building does at times. Aluminum does not get damaged or degraded by the natural elements it is exposed to, nor by salt or oxidation. While the paint may fade, the roof will always last.
Highly costly, but providing reliability, beauty and style all in one, copper roofs can be something of a luxury. Unpainted copper has its personal natural elegance and classical beauty which will never go out of style. Copper is quite similar to aluminum simply because it truly is really long lasting though the colour will slowly change, but even then it doesn't matter because the 'aged copper' look is quite sought after. Simply because of its prohibitive cost, copper is hardly ever used on residential houses. Only the most exclusive houses may have copper roofs installed.
The first and most significant step for metal roof upkeep would be to maintain it clean. Cleaning will help to minimize the build up of algae, mildew and mold, and will go far towards ensuring that the roof staysin the very best possible condition.
