Straight bond v staggered Bond on roof

[richie9648]

Having a debate about straight bond v staggered Bond on extension roof.  Builder says they can be bonded straight - I say not as it will have higher risk of leaks

 

tell me he is talking nonsense please??

 

 Thanks

What tiles or slates are we talking about please? 

[richie9648]

Quinn concrete tiles as per below:

They will look shite straight, they need to be staggered to look correct.

[bassanclan]

"TILES The roof is to be covered with WESTERN SLATE flat tiles as per sample approved and laid in even courses of not more than 345mm gauge and not less than 75mm headlap. The tiling is to be broken bonded."

they are interlocking so would be water tight laid straight with the correct headlap, as would a single row on its own for example. But as others said would look 'different'.

they are cut with a saw, concrete interlocking as they may not be a half.

[tonyshouse]

When I used to buy them the halves worked for a perfect half bond

You can just cut a tile in half and have a perfect half bond.

[tonyshouse]

Not quite , there needs to be a big half and a small half ?
