Things get technical
When different types of metals come into contact with each other, and particularly when water is present, chemical reactions take place. It’s important to know which metals should never touch, both to ensure the longevity of your roof, and that you are covered by the warranty, especially when adding things like solar panels and aerials at any point.
Design, pitch and aspect
ColorCote pre-painted metal roofing and cladding offer the biggest choice of colours and substrates. These can be rollformed or pressed into a range of profiles that give unmatched design flexibility, will look great, and be warranted to last. ColorCote roofing has the strength to span wide spaces with simple and lightweight support systems and can be bent or curved to suit an almost unlimited range of innovative designs and roof pitches.
The house design will affect the life of your roofing and cladding. Avoid overhangs and designs that create unwashed areas. They won’t be naturally washed down by rainwater so caked dirt, salts and other corrosive elements will accumulate.
Good design can get rid of most unwashed areas at the planning stage. Roofs need to be washed down on a regular basis, so consider access. If the pitch of the roof is too steep to walk on safely, you might have to hire a cherry picker or crane for periodic maintenance.
The aspect of the roof is important, especially in severe environments. Salt-laden air driven in from the sea under the roof profile will accelerate corrosion. Spouting, valleys and low-pitched roofs also need to have the correct fall to prevent ponding which can accelerate potential corrosion.
