Nailing Concrete Roof Tiles

[veedee]

I have concrete interlocking tiles that need to be nailed down

Could anyone confirm whether nailing every third row is the recommended method? i.e. nail first row, then miss two rows, then nail the one above

I live in wind zone 1

I've just read that according to BS 5534

- All tiles must be fixed (nailed). As a minimum.

- In addition, a fixing calculation should be run to determine if any extra fixings, such as clips, are required.

Isn't this all a bit overkill for wind zone 1?

How much extra effort is it for an extra nail a tile versus tile repairs Next big storm ??

Yes, but it is my understanding that this was not a requirement a few years back.

That coupled with the fact that we have never had a tile fly off the roof in the 40+ years it has been on the roof

Also, nailing every tile makes future removal/ replacement cumbersome.

I am happy to follow the guideline, it just seems like overkill and I very much doubt that professional roofers are nailing and adding extra fixing to new roofing jobs

Does anyone have a link to the fixing calculator as according to BS 5534, I may have to add additional fixings.

Dont know the regs but what about nailing every other tile instead of missing complete rows that way most tiles will have a nailed one next to them holding them down, but would nail all tiles on the edge and last ones next to the ridge.

Tell that to your insurers..
