Rusty nails and roof tiles are not a good combination.
15 to 20 years is how long it takes for a regular , bright (non-galvanized) nail to rust. So if you find yourself with a leaky roof, a rusty nail might be your problem.
When roofing nails rust they expand so much they can cause the top of a roof tile to split. This is usually only noticed when your roof begins to leak. By this stage a lot of avoidable damage has already occurred and an unnecessary repair to your tiled roof needs to be carried out. I have found this to be a very common problem throughout many Melbourne suburbs.
So, what happens if you have a leaky roof due to rusty nails? Here begins a long and lengthy process of locating the tiles with the rusty nail and replacing them with new tiles and, of course, galvanized nails. It is not as simple and just finding the cracked roof tiles and replacing those, because even if the other rusted nails haven’t split the roof tiles, it’s only a matter of time before they will, causing even more damage to the internal areas of your home.
Rusted nails and split roof tiles are easily prevented, if the roof tiler uses the right, galvanized nails in the first place!
