aluminium roofing benefits

When it comes to the roofs over our heads, we all want to ensure there's no compromise when choosing the very best materials to shelter us. Whilst there's certainly pro's and cons to using any kind of roof, there are specific benefits to aluminium roofing that have made it the best choice for contractors and home-owners alike, with a sterling reputation that's not likely to cease.

But why is aluminium so useful for roofing? In this entry of the Austen Knapman blog, we list the indisputable reasons why aluminium angles and bars are the best thing to have lined up above your head!

Easy to Install

Requiring no complicated fixings or additional materials, aluminium roofing panels simply need to be cut to roof trusses length, and fixed together with nails. Cut-to-size aluminium can easily be shaped into the necessary lengths and edge trims, can be installed on a reasonably light supporting structure and because they are easy to dismantle and transport, more and more home-owners opt for this non-ferrous metal when the time comes to re-roof their abode.

Light Weight

Speaking of handling, one of the most lauded pro's for using aluminium angles in roofing is it is supremely lightweight. Because of this, conveying from one point to another is extremely easy, whilst it's impact on a building's weight and structural effects are virtually non-existent. Aluminium doesn't contain any iron, which helps to reduce its weight dramatically, to the point where its actually one third the weight of corrugated galvanized steel sheets and one seventh that of standard asbestos corrugated sheets. All this weight, or lack thereof, reduces labour costs and effort, and makes aluminium a consistently efficient choice from the moment installation begins.

Rust and Corrosion Resistant

Once it's shining on the top of your house, aluminium pretty much looks like new forever. Due to their anti-corrosive properties, an aluminium roof can remain rust or wear free for years, even decades. This is a huge departure from asphalt roofing, which requires replacement and re-roofing roughly every 15-20 years. For long term benefit, the weatherproof and maintenance free qualities of aluminium angles are a good fit for its durability, outstanding strength and flexibility.

Does not Require Structural Reinforcement

Unlike heavy tile and slate, aluminium roofing doesn't require structural reinforcement. Aside from the obvious uses this has in the construction process, it means the overall weight on your house is significantly reduced. Even though rafters may be an attractive choice in many regards, they need to be thick to prevent twisting under pressure, which ultimately makes them difficult to handle on site, and very expensive. The high strength-to-weight ratio of aluminium meanwhile makes it a popular choice for facades and cladding of non-residential buildings; with its low load on the supporting structures of buildings helping to add to its insulation properties, and increase energy efficiency.

Environmentally Friendly

Lastly, we can't mention aluminium's efficient nature without tipping a hat to its environmental excellence. As we mentioned in our previous blog on why aluminium leads the way in green architecture, the amount of waste materials in construction is ground to a halt with aluminium. With the potential to recycle 100% aluminium without any loss to its natural quality, the recycling process itself also takes up to 95% less energy than its original production. For anyone questing for the ultimate green home, the best place to start is with an aluminium roof.
