Improper fastening of the roof tiles – Your assessment

Hello everyone! I would be interested in your assessment regarding the following issue. As additional information: We live in a newly built house, moved in about 5 months ago.

It concerns the fastening of our roof tiles (specifically the verge tiles) and storm damage caused by storm Sabine. Several tiles were damaged/lifted by this storm, predominantly at the verge. This side of the roof and position correspond to the main impact area or edge.

On the tile that fell to the ground, it can be seen that it was not fastened at its intended pre-drilled hole/recess. The recess is not pierced; there could be no screw or nail here (see attached picture). According to the manufacturer and, as far as I have read, the professional rules of the DDH, every verge tile is to be fastened.

For us, this means that we can no longer assume that we have a properly roofed or fastened roof on our house. This would mean an intensive inspection and rework by the manufacturer. In addition, in our opinion, the manufacturer is now obliged to cover the repair costs of the roofer, whom we commissioned directly the next morning (i.e. yesterday). Of course, this should be resolved as quickly as possible to avoid consequential damage. Furthermore, we think our insurance will not cover this damage if there is suspicion of incorrectly fastened tiles.

How do you see the whole situation? Are our views justified/understandable? We have also reported the problem directly to the house builder and are currently waiting for feedback there.

Maybe the bricks weren't screwed at all but fastened with storm clips? That's how it was with us anyway.

Storm clips are said to have been used according to the manufacturer. However, it is not explicitly stated where. According to the roofer who briefly inspected the damage yesterday, clips are more commonly used across the surface.

As I understand the specification for eaves tiles, however, screwing or nailing is required here. The tile manufacturer also specifies: "Each eaves tile is fixed with a wood screw, diameter 4.5 mm, with a screwing depth of 24 mm in softwood (support battens). "

Sorry for the double post but I have taken the advice from to heart and asked two roofers in the area. The statements were quite clear: one clamp is not enough at this point, every verge tile must be screwed. The second roofer also pointed out our exposed location (the house stands on a hilltop at just under 470 m above sea level).

In the structural calculations for our house, I have now also found the calculation for the storm clamps. It is described here that in the area where clamps are used at all, only every third tile is clamped. In my opinion, that would be far too little for the verge anyway.

It’s best if you report it to the insurance and then have the new craftsman screw the verge boards...

What does the creator say about that?
I wouldn’t want to argue with the manufacturer about it, which could possibly end up in a legal dispute.

What kind of damage are we even talking about?

To what extent is the "manufacturer" (=of the brick or the house?) involved here? If there is a defect in the execution, as you suspect, claim it under the warranty.

Do I understand correctly that "the roofer" is now another party that has already been commissioned? Why? Did damage have to be averted and the roofer who originally covered the roof was not reachable?
