ᐅ Roof tiles – battens spaced at 32 cm or 34 cm intervals

Hello, I have a simple question:

What is the difference between 32 mm (1.3 inches) and 34 mm (1.3 inches) battens for concrete roof tiles on the gable side?

How does it affect the installation?

I couldn’t find anything online except that it depends on the roof pitch.

I would appreciate any input.

Regards

Found something online after all

Hello Schornstein,

I actually found something online. Take a look at the following webpage or PDF. It explains the topic mentioned above quite well. I hope this helps you.

Otherwise, you should talk to the company that sold you the concrete roof tiles. They should know the details as well.

Good luck.

Hello,

If your roof pitch is low, you need to overlap the concrete tiles more. Since concrete tiles do not have a head lap, this doesn’t matter on the main field of the roof. However, because the edge tiles have a lateral notch where they overlap, you need different cut-outs—either the 32 mm (1.3 inches) or 34 mm (1.3 inches)—for the battens. Usually, the 34 mm (1.3 inches) size is used. If you want precise information, just contact me again and I will check the technical guidelines. Otherwise, I suggest you also look into clay roof tiles (like Braas V9 or Erlus Max 58). Depending on the model, they can be similarly priced to concrete tiles but offer better quality, as they are fired, have head and side laps, and so on.

Best regards

Incorrect Batten Spacing

It appears that our roofer miscalculated the batten spacing. For the tiles measuring 42 cm (16.5 inches) and a roof pitch of 35 degrees, the battens were spaced at 35 to 36 cm (14 to 14½ inches). According to the manufacturer, the batten spacing should not exceed 34.5 cm (13.6 inches). We noticed this at the gable tiles because the gaps between the recesses seemed too wide. We brought this up with the roofer, but he does not want to listen. Should we insist that he correct it, or leave it as it is? Will this cause serious problems?

Hello,

According to the professional regulations in roofing, for profiled single coverage with a raised side seam (these are usually standard tiles), a head lap of 7.5 cm (3 inches) is required when the roof slope is over 30 degrees. This explains the maximum batten spacing of 34.5 cm (13.6 inches) specified by the manufacturer. Any other spacing is considered a defect in the roof and must be corrected. I usually space the battens at around 33.5 cm (13.2 inches), depending on the rafter length and calculations.

I believe they did not want to install a small row of tiles in your case and calculated the batten spacing accordingly, which violates the professional regulations. I hope I could help you.

Thank you for the replies!
It’s good to know that one is not clueless and can trust their own eyes. Professionals often try to make laypeople feel stupid with their questions. Of course, this does not apply to everyone, but unfortunately, it is true in our case.
Thanks again.
