How do roof tiles stay in place?
Most roof tiles are fixed in place using nails. Whether it’s aluminium, steel or copper, the nails attach tiles to roof battens, which are laid horizontally across the surface of your roof. Because the nails are used at the top of the tiles, they’re usually hidden by the overlapping tiles above.
How much should roof tile overlap?
Your tiles should overlap one another by between 75mm and 100mm, depending upon their size as well as the pitch of your roof. This should mean that the gauge of your roofing battens will be around 32-35cm, measuring from the top of one batten to the top of the one below it.

Do you have to nail concrete roof tiles?
For all roof areas and rafter pitches, every tile should be mechanically fixed with at least a nail, a clip, or a combination of these options that provide adequate combined resistance to the wind uplift loads on the tiles. For roof pitches of 45° and above, each tile should be fixed with at least one nail.
Why do roof tiles slip?
The nails that hold your tiles or slates in place can eventually rust and wear away, leaving them too weak to hold the tiles. In some cases, tiles can even slip out of place because the wood has weakened. Water damage to roof battens, for instance, means there’s less integrity holding onto the tiles.

Can you screw roof tiles?

How do roof tiles interlock?
Laying interlocking tiles Start at the eaves and work right to left by hooking the nibs over the wooden battens before laying the next tile alongside it. As these are interlocking tiles, each row goes directly above the other with no need to stagger as the joints are automatically sealed by overlaps.
Do you nail interlocking tiles?
Fixing. Aluminium nails should be used in preference to galvanised nails as aluminium will not corrode whereas the galvanise coating will tend to.
